Biomedical engineers at Brown University have created a wound dressing that releases antibiotics only when harmful bacteria are detected. In a new study, the team found that the material may quickly eliminate wound infections and speed healing while cutting back on unnecessary antibiotic use. Overuse of antibiotics is a key factor behind antibiotic resistance and difficult-to-treat “superbug” infections, which kill tens of thousands of people worldwide each year.

The material is a smart hydrogel packed with antibiotics and designed to be applied directly to a wound beneath a bandage. It responds to an enzyme made by many harmful bacteria. When that enzyme is present, the hydrogel begins to break down and releases the antibiotics stored inside. If harmful bacteria are absent, the hydrogel remains intact and keeps the medication sealed away.

“Antimicrobial resistance is a major problem worldwide, so we need better approaches for how we use antibiotics,” said Anita Shukla, a professor in Brown’s School of Engineering who led the development of the smart hydrogel. “We’ve developed a material that releases antibiotics only when harmful bacteria are present, so it limits exposure to antibiotics when they’re not needed but still provides these important medications when they are needed.”

In the study, published in Science Advances, the researchers tested the hydrogel and found that it was highly selective for enzymes produced by common bacteria that cause wound infections. The findings also suggest that the material may clear infections and support wound healing more effectively than a hydrogel dressing currently used in clinical care.

For decades, the semiconductor industry has boosted computing power by making transistors smaller and fitting more of them onto a single chip. That strategy has fueled remarkable advances in electronics, but it is now approaching fundamental physical limits. As devices shrink toward atomic scales, engineers must contend with the constraints of material properties and the effects of quantum mechanics.

Researchers believe the next major advance may come not from making chips smaller, but from building them upward.

A team at the University of Illinois Grainger College of Engineering has demonstrated a new way to stack layers of silicon circuits directly on top of one another, creating compact three-dimensional chips that could deliver greater computing power while using less energy. Their work, published in Nature, overcomes a major obstacle that has long prevented widespread adoption of this approach.

“Take something as simple as static random-access memory, which is universal in CPUs and GPUs. Today it takes six microelectronic devices called transistors on a single plane to store one bit of information. With vertical integration, you can distribute them across multiple layers. It’s like replacing a sprawling suburb with high-rises: you get the same functionality, but the spatial footprint is reduced while making communication between layers faster and more efficient,” said Qing Cao, a professor of materials science and engineering at Illinois Grainger Engineering.

Researchers at the University of Houston's College of Pharmacy have discovered an unexpectedly simple strategy to improve the performance of mRNA vaccines and gene therapeutics: adding salt. The findings, published in Small, address one of the biggest challenges facing modern gene medicine—getting fragile therapeutic material to the right place inside cells.

"We are introducing salt-loaded lipid nanoparticles as a novel and broadly applicable design principle for gene delivery," said Fanfei Meng, assistant professor and Presidential Frontier Faculty member in the Department of Pharmacological and Pharmaceutical Sciences. "What makes this exciting is that we can significantly improve delivery efficiency without needing to invent entirely new materials."

Lipid nanoparticles, or LNPs, are tiny fat-based delivery vehicles widely used to transport fragile genetic material into cells. They became widely recognized during the COVID-19 pandemic through mRNA vaccines developed by Moderna and Pfizer. Today, scientists are also using LNPs to develop new treatments for cancer, rare diseases and genetic disorders.

Despite their success, a major obstacle has remained. After entering cells, much of the therapeutic cargo becomes trapped inside endosomes—membrane-bound compartments that prevent the genetic material from reaching the interior of the cell, where it must go to function properly.

Researchers have long considered this "endosomal escape" problem one of the major bottlenecks limiting the effectiveness of mRNA vaccines and other gene-based medicines.

"Many gene therapies fail because of this," said Meng. "We found a surprisingly simple way to help more of that cargo escape."

The escape plan
Meng and his research team discovered that loading salt into lipid nanoparticles creates pressure inside the endosomes, helping release the therapeutic material into the cell, where it can become active. The team believes the strategy could eventually help improve a wide range of treatments, including mRNA vaccines, gene-editing technologies and other nucleic acid-based therapeutics.

The approach relies on basic physical principles rather than complex chemical redesigns, making it easier to adapt for future therapies and large-scale manufacturing.

Plants, animals and microorganisms constantly communicate through chemical signals. A research team has now shown that these signals merge in the environment to form complex "chemical landscapes" that have effects far beyond those of their individual components. Published in Nature Ecology & Evolution, the findings open new perspectives on understanding biodiversity, ecosystems and the impacts of global environmental change. The study was coordinated by Bielefeld University.

How does a butterfly find a suitable mate and then the right host plant for its offspring? How do pollinators locate the most attractive flowers? Many organisms rely on chemical signals to accomplish these tasks. These invisible messages permeate air, water and soil, helping organisms navigate complex environments.

Researchers say that these chemical signals do not act in isolation. Instead, compounds released by different organisms mix within their shared environment and form complex chemical patterns. Together, they create a dynamic "chemodiversity landscape"—the total chemical diversity present within a habitat.

"We already know that individual chemical compounds convey important information. Our work shows that when many compounds interact, new properties can emerge that cannot be predicted from the individual components alone," says Dr. Thomas Dussarrat of Bielefeld University, one of the study's lead authors.

When diversity creates new functions
In their review article, the researchers synthesize findings from across the field of chemical ecology. They argue that chemical mixtures operating at the landscape scale can generate novel ecological effects. Scientists refer to these as "emergent functions"—properties that arise only through the interaction of many components. Such effects may influence how plants interact with pollinators, herbivores and microorganisms, thereby shaping entire ecosystems. Such chemical patterns could also arise at the interfaces between terrestrial and aquatic ecosystems, thereby influencing interactions between different habitats.

Relevance for biodiversity and climate change
Another lead author of the study is Dr. Robin Heinen of the Technical University of Munich (TUM). "With the concept of the chemodiversity landscape, we expand our perspective from individual organisms to entire ecological communities. This enables us to better understand ecological processes in natural ecosystems," says Heinen.

The new concept not only advances an understanding of ecological relationships. It may also enable practical applications in the future, for example in biodiversity conservation, the development of sustainable agriculture, and the prediction of climate change impacts.

The researchers therefore see a strong need for further research to better understand the significance of these largely hidden processes. Environmental changes such as drought, climate change and species loss may also alter nature's chemical landscapes, with consequences for numerous interactions among organisms.

For decades, physicists have pursued a goal that sounds nearly impossible: to build a clock that keeps time using an atom's nucleus rather than the electrons orbiting it.

Now, researchers have demonstrated the first functioning nuclear clock  — an advancement that could eventually lead to more robust timekeeping devices and new ways to search for dark matter and physics beyond the Standard Model.

"Having worked in this field for more than 15 years, it is just beautiful, how a very 'wild' idea such as manipulating an atomic nucleus with a laser has turned into reality," Thorsten Schumm, a professor of quantum metrology at the Vienna University of Technology and a member of the research team, told Live Science via email.

How is a nuclear clock different from an atomic clock?
Today's most accurate clocks are optical atomic clocks, which measure the frequency of electrons jumping between different energy levels inside atoms. These clocks are so precise that they would lose less than a second over a 100 million years.

A nuclear clock works similarly, but it uses a transition within the nucleus itself, where the nucleus jumps between energy levels. Because the nucleus sits deep inside the atom, it's far less affected by external disturbances from things like electric or magnetic fields. According to Schumm, the nuclear transition can be 1,000 to 10,000 times less sensitive to environmental noise than atomic transitions are.

Stars shine because atoms fuse in their interiors, releasing energy. When a very massive star has exhausted its nuclear fuel, radiation pressure can no longer provide sufficient counterforce to gravity. The star then collapses under its own mass until only a single point remains: the singularity.

While the formation of a black hole appears plausible, black holes themselves continue to pose major challenges for science. How can 10 billion solar masses concentrate at a single tiny point? How can spacetime be curved infinitely at that point, the singularity? At this stage, the laws of physics break down, making it impossible to predict what happens. Moreover, black holes conceal all information from observation: Everything, including light, disappears irretrievably beyond the event horizon.

Filled with dark energy
It is therefore possible that black holes are in fact entirely different objects, such as ultra-compact stars, which cannot be seen because of their intense gravity and are therefore also called gravastars. In addition to ordinary matter present in their outer layers, they would be filled with dark energy, which exerts an outward pressure and stabilizes their mass, which wants instead to collapse. Gravastars are easier for physicists to accept than black holes because they do not possess a singularity or an event horizon and yet are almost as massive and compact as black holes. What had remained unclear, however, was how such gravastars could form in practice.

The theoretical physicists Daniel Jampolski and Professor Luciano Rezzolla have now presented, for the first time, a dynamic solution to the field equations of Albert Einstein's general relativity describing the collapse of a star that could lead to the formation of such a gravastar. The solution showed that the collapse may trigger the creation of a mini-universe inside the collapsing matter, not very different from the Big Bang from which our universe emerged. Like our own universe, its expansion is driven by dark energy. The findings are published in the journal Physical Review D.

In this way, the expansion of the new universe counteracts the gravitational forces and halts the collapse of the star before a black hole can form. In this process, an equilibrium is established between the expanding mini-universe and the collapsing matter, and this equilibrium is what leads to a stable gravastar. With this solution to general relativity, the Frankfurt physicists have provided the first answer to a question that scientists have been debating for 25 years: How do gravastars form during the collapse of ordinary matter?

An international team of researchers has identified at least two biologically distinct forms of autism by examining how different regions of the brain communicate with one another. The findings could help advance more precise and personalized approaches to autism care and support.

The researchers found two recurring patterns of brain connectivity. In one group, known as the “hyperconnectivity” subtype, communication between brain regions was stronger than usual. In the other, called the “hypoconnectivity” subtype, communication was reduced.

Brain Connectivity Patterns Reveal Autism Subtypes
According to the research team, this work represents the first systematic attempt to interpret human brain imaging patterns (via fMRI) by tracing them back to underlying biological mechanisms identified in mouse models. By connecting specific brain connectivity patterns to particular biological pathways, the study provides a potential framework for future precision medicine strategies.

To investigate these relationships, the researchers analyzed functional connectivity in 20 mouse models and examined brain scans from 940 children and young adults with autism, along with scans from more than 1,000 neurotypical individuals.

The analysis uncovered two reproducible autism subtypes. The hypoconnectivity subtype was associated with synaptic pathways, while the hyperconnectivity subtype was linked to immune-related biological systems. Together, these two groups represented approximately 25% of the people with autism included in the study.

From self-driving cars navigating busy streets to drones surveying disaster zones, lidar has become one of the most important technologies for helping machines perceive the world in three dimensions. By sending out rapid pulses of infrared light and measuring their reflections, lidar systems can build highly detailed maps of their surroundings in real time.

But today’s most powerful lidar sensors often come with major drawbacks: they are bulky, expensive, and rely on moving mechanical components that can wear out over time.

Researchers at MIT have now demonstrated a potential solution. They developed a new silicon-photonics chip that could enable compact, durable lidar systems with no moving parts. Silicon photonics uses semiconductor technology to manipulate light rather than electricity, opening the door to lidar sensors that are smaller, cheaper, and easier to manufacture at scale.

One of the biggest obstacles facing silicon-photonics lidar has been its limited field of view. Existing chip-based systems struggle to scan wide angles, while methods for expanding their coverage typically introduce noise and reduce measurement accuracy.

To overcome this challenge, the MIT team designed an array of integrated antennas that dramatically reduces unwanted interference, known as crosstalk, between neighboring antennas. Their approach allows a lidar chip to scan a much wider area while maintaining the low-noise, high-precision performance needed for demanding applications such as autonomous vehicles, aerial mapping, and construction-site monitoring.

Solid-State Lidar Could Transform Autonomous Navigation
The breakthrough could support the development of advanced lidar sensors for applications such as autonomous driving, aerial surveying, and construction site monitoring.

“The functionality we demonstrated in this work solves a fundamental problem for integrated optical-phased-array technology, enabling future lidar sensors that can achieve significantly higher performance than we could demonstrate previously,” says Jelena Notaros.

We often hear about glacier melting and predictions of what climate change could do. But very little is mentioned about the effects on ecosystems or the animals that call them home. To redress some of this imbalance, an international team of researchers set out to map this hidden biodiversity. Their findings are published in the Proceedings of the National Academy of Sciences.

Rich glacial ecosystems
Glaciers are more than just massive chunks of moving ice. They are also teeming with a wide variety of terrestrial and freshwater animals. In their study, the team combed through prior research and identified at least 152 species known to live on glaciers. These include rotifers (microscopic animals), springtails (small hexapods closely related to insects) and tardigrades (microscopic, eight-legged invertebrates known as water bears).

To find out exactly what lives in these frozen worlds, the study authors reviewed 2,695 published papers, narrowing them down to 124 studies about terrestrial and freshwater glacier habitats.

They created a global map containing 482 verified records of glacier-dwelling animals, including the name of the glacier where each lived and its habitat type. The organisms were divided into two groups: glacier animals (use glaciers but can live elsewhere) and glacier specialists (found only on glaciers). The researchers then overlaid these maps with predictions of glacier melt from climate change models to estimate how much habitat would disappear by 2100.

What if some of the Universe’s oldest objects are actually older than the Big Bang itself?

A new study from the University of Portsmouth suggests that ancient black holes may have survived from a time before the Universe as we know it existed. These hypothetical relics, described as “cosmic fossils,” could have endured a dramatic cosmic transition and may still be scattered throughout the cosmos today. If they exist, they could help solve one of astronomy’s biggest mysteries: the identity of dark matter, the invisible substance that appears to outweigh ordinary matter and shape the growth of galaxies.

The research challenges the conventional view that everything began with a singular Big Bang. Instead, it explores a “bounce” scenario in which the Universe was once contracting before reversing into the expansion we observe today. In that picture, some structures may have survived the transition, carrying information from a cosmic era that predates the Universe’s earliest observable light.

Recently, somewhere in the Southern Ocean, a team of fishermen hauled this up from the deep: an adult colossal squid, an animal the size of a school bus and the biggest invertebrate on the planet. But despite its size, we've never found and filmed a fully grown one alive in its natural habitat. Why? For 100 years, people assumed we hadn't seen a big one in the deep because they were rare, elusive, maybe even close to extinction.

But we were wrong. Sperm whales constantly eat colossal squid. In fact, around 77% of the squid biomass in Antarctic sperm whale stomachs is colossal squid. And if you back-calculate to work out how many colossal squid must exist to sustain that many sperm whales, the answer is tens of millions in the Southern Ocean right now. So, we're talking about an animal the size of a school bus. There are tens of millions of them, and yet they're invisible to us.

I've spent the last few years dropping cameras into the deep ocean and the more I understand about this animal, the more I realize that this isn't really a story about an animal that's hard to find. It's a story about how we've been looking and why pretty much everything we've done in the past has been wrong, and what we could possibly do to fix it.

Should you marry that person? Quit a steady career to retrain? Move across the country, away from aging parents? Sit with any of these and watch your mind spin. You weigh what you'd gain against what you'd lose. You run the numbers. And still no answer arrives.

Big decisions do this to us. They are rare, life-shaping and hard to undo, and they refuse to be solved like a sum.

Researchers recently used AI to analyze more than 100,000 real dilemmas posted online. They found choices pulled in dozens of directions at once, far from the tidy two or three variables we imagine. Big decisions are messier than they look.

I study how people make life's biggest decisions. In research, I asked more than 600 people to describe their 10 biggest decisions. Thousands more have since mapped their own choices in an ongoing study. Marriage, children, career changes, house purchases and relocations come up again and again.

My study didn't hand me a checklist you can use when faced with a big decision. But it did show what separates the decisions people are later glad of from those they regretted. Read alongside the wider research, those factors fall into a rough order worth trying.

Does it seem as though more people are coming out as neurodivergent these days? Perhaps you've heard complaints that social media—particularly TikTok—is driving a trend. Or maybe you've encountered the suggestion that neurodivergence has somehow become fashionable, a label people adopt for attention, status or belonging.

For neurodivergent people, these claims can be deeply dismissive. They reduce complex experiences and real struggles to a passing cultural craze.

My research suggests something quite different. Far from being a modern phenomenon, neurodivergence has a long history. In other words, people whose ways of thinking, sensing or behaving differed from social expectations have always existed. Members of my research project have described discovering these historical figures as like finding neurodivergent ancestors.

Of course, this is not about diagnosing people who lived centuries ago with autism, ADHD or other conditions. Diagnostic categories have their own history. They change over time and can be shaped by specific cultural and geographical contexts. Moreover, I am not a doctor or a psychologist, and I am not interested in retrospectively diagnosing historical people.

What interests me is something broader: the many people in the past who were understood—by others or by themselves—as different.

One example is Hannah Allen. She was an English widow who published an account of her experiences in 1683. She wrote about periods of profound melancholy and hearing voices, drawing on journal entries she kept during those difficult years. Stories like Allen's remind us that people have long searched for language to describe minds and experiences that did not fit comfortably within accepted norms.

People have always adapted and reshaped the language available to them. Today, clinical terms regularly spill into everyday conversation. People talk about being "anxious" about an exam or "depressed" by bad weather, without necessarily claiming a diagnosis. Literature has always transformed and enriched our understanding of medical and psychological concepts.

In my work, I define neurodivergence as ways of thinking, sensing or behaving that diverge from social expectations. What's also important is that those expectations vary across time and place. Behavior regarded as unusual in one context may be entirely acceptable in another.

People who are hesitant to try insect-based foods may enjoy the experience more than they expect—and can become more open to expanding their diets in the future, according to research published by the American Psychological Association.

The study, published in the Journal of Neuroscience, Psychology, and Economics, examined how consumers respond emotionally and physically to insect-based foods, which are increasingly being explored as a sustainable alternative to traditional animal protein sources. For example, the European Union officially recognized insects as a novel food source in 2018 and has approved several insect food sources since then. The lineup includes yellow mealworms, migratory locusts, house crickets and lesser mealworms sold frozen, dried or even powdered.

Lead author Andreia C. B. Ferreira, a Ph.D. candidate at the University of Beira Interior in Portugal, and her colleagues wanted to find out more about how consumers might respond to these new options. To do so, they combined traditional surveys with neuroscience tools that measured participants' brain activity and heart rate while they sampled insect food products.

The study involved 38 adults in Portugal between the ages of 18 and 55 who had never tried insect-based foods before. Participants first completed a survey about their awareness and opinions of insect-based products. They then sampled both an insect protein bar and a cereal bar while researchers recorded their physiological responses using electroencephalography (EEG) and electrocardiography (ECG).

The researchers expected participants to have low awareness of insect-based foods, prefer the cereal bar and show stronger physiological reactions to the insect-based product. Instead, the findings revealed that people were often more curious and receptive than expected.

In addition to molecules, it can also help scientists track the weather on these exoplanets. By measuring precise Doppler shifts in these spectral lines, researchers can determine orbital velocities—in other words, how weather is moving on a planet light-years away. Doing so will require a coronagraph to block out the light coming directly from the exoplanet's star, but no coronagraph is perfect and will always let some starlight through. Higher-resolution spectrographs will make it much easier to separate that "noise" from the signal of the light from an actual planet.

This all sounds great in theory, so why haven't we done it already? Simply put, the technology was too big, too heavy and too overcome with noise to be useful. Weight is a critical factor in any telescope, as it directly ties to the cost of the mission. And sensitivity to "dark current" (i.e., electric current caused even when there is no light hitting a sensor) made much of the data older generations of higher-resolution sensors collected useless anyway.

According to Jaffe and his team, though, those problems have largely been solved—at least on the ground. The first is by a new technology called silicon immersion gratings and grisms. These force light to diffract from inside a high-refractive material like silicon, compared with traditional gratings that bounce light off a mirrored surface. This allows engineers to drastically reduce the size (and therefore weight) of the spectrograph and has the added bonus of not requiring any moving parts to adjust mirrors.

The second technological breakthrough is in the area of avalanche photodiode arrays (APAs). These new detectors have near-zero "dark current," and the noise introduced by the sensor itself is less than the signal introduced by a single photon. These baselines make it much more feasible to capture the right kind of light from an exoplanet and ensure it can be differentiated from the starlight of its host star.

Memory is one of the strangest abilities you possess. Your brain uses an incredibly complex biological system to preserve moments from your past that no longer exist, allowing you to revisit experiences from years ago. But memories are not always recordings of reality. In fact, every time a memory comes under the spotlight of your attention, it can melt and change a tiny bit.

What exactly is a memory, how is a moment in time stored inside your brain, and why does remembering something slowly rewrite the story of your life?

Researchers at Yale University have developed a new brain-computer interface (BCI) that allows people to play video games using only their brain activity. By using real-time fMRI (functional MRI), the team demonstrated that users can control a computer efficiently through their thoughts alone.

The study revealed that brain activity follows established neural pathways. Researchers found that learning to use a BCI becomes much easier when the system is designed to work with those existing pathways rather than against them. When a BCI aligns with the brain’s natural organization, users gain control quickly, and their brain activity adapts to support learning. Systems that do not match this structure produce little or no improvement.

Why Natural Brain Pathways Matter for BCI Learning
“The implications are broad, from helping people with motor or communication disorders to developing treatments for depression or anxiety to building the next generation of consumer games and technologies: interventions designed around the brain’s natural geometry are likely to be faster, more effective, and more accessible,” said Erica Busch, the first author of the study, who recently completed her Ph.D. at Yale.

Although researchers have worked on these systems for years, many human BCIs have had limited success. Earlier fMRI-based systems, which rely on real-time neurofeedback from scans that track changing patterns of brain activity, often required as many as 10 lengthy training sessions. Even then, improvements were relatively small. Roughly one-third of participants never learned to control the system, regardless of how much they practiced.

Busch and her colleagues believed the problem stemmed from how these systems were designed. Often, BCIs required the brain to learn patterns that did not fit its natural organization. The researchers proposed that more advanced tools capable of tailoring neurofeedback to each brain’s underlying structure could significantly improve both learning speed and performance.

“Could we build a system smart enough to discover that geometry in real time, using noninvasive brain imaging?”

Fentanyl has become one of the deadliest drugs in the United States, with fentanyl and related synthetic opioid variants now claiming more lives each year than car crashes and gun violence combined. When taken in excessive amounts, these drugs disrupt critical brain functions and can stop the signals that control breathing. Although existing treatments can reverse an overdose, they must be administered quickly to be effective.

Researchers at Scripps Research are exploring a very different strategy. Instead of treating an overdose after it happens, they have developed an experimental vaccine designed to train the immune system to neutralize fentanyl before the drug can reach the brain. Their findings, published in the Journal of Medicinal Chemistry, suggest the vaccine may protect not only against fentanyl itself but also against many fentanyl-related “designer drugs” that are modified to increase potency or avoid detection.

“What this research shows us is that we don’t have to keep playing catch-up with every new synthetic designer drug that emerges,” says senior author Kim Janda, the Ely R. Callaway, Jr. Professor of Chemistry at Scripps Research. “By training the immune system to recognize the entire fentanyl class—not just individual structures—we can stay ahead of illicit drug traffickers.”

A prototype quantum sensor developed by researchers at Imperial has demonstrated for the first time that a key principle behind next-generation quantum detectors can work under realistic conditions.

The study shows how comparing two long-baseline atom interferometers, instruments that use lasers to precisely measure the behavior of atoms, allows experimental noise to be effectively canceled.

This enables signals to be recovered even when individual measurements are overwhelmed and opens the door to searches for gravitational waves from the early universe and signatures of exotic forms of dark matter.

Canceling noise in quantum measurements
Understanding what the universe is made of and identifying new sources of gravitational waves remain major challenges in modern physics.

Both problems require measuring extremely small signals that can easily be lost in background noise. Finding reliable ways to detect them is essential for exploring parts of the universe that current experiments cannot access.

It is an oft-quoted—and always alarming—statistic that 34 percent of the world’s carbon emissions are caused by the construction industry, with a significant portion borne specifically from the production of concrete required to erect a standard structure today. At the same time, we are facing a global housing crisis, as a large population of people moves from rural towns into cities, outpacing the number of affordable, high-quality units being built to accommodate them.

So how does one put these two crises in alignment? Around the world, innovative architects, scientists, and engineers are exploring building techniques and materials that can create places to live without hastening climate change. The secret? Keeping it local.

The concept of embodied carbon—the emissions released across the lifespan of a material, from extraction, manufacturing, and transportation down to disposal—dictates that the most sustainable architecture is built from its surroundings. Forward-thinking minds are tapping both high- and low-tech building methods and materials in every region of the world. From solar-powered pods that can handle the most extreme weather on Earth to residences built, literally, from the earth that surrounds them, each project presents a solution specific to its site, culture, and vernacular—but that can potentially be adapted for use in farflung places.

The design lessons that can be gleaned from all the examples below are found in their commitment to both planet and people.
