A New Cosmic Tension: The Universe Might Be Too Thin

Cosmologists have concluded that the universe doesn’t appear to clump as much as it should. Could both of cosmology’s big puzzles share a single fix?

The cosmos is starting to look a bit weird. For a few years now, cosmologists have been troubled by a discrepancy in how fast the universe is expanding. They know how fast it should be going, based on ancient light from the early universe, but apparently the modern universe has picked up too much speed — a clue that scientists might have overlooked one of the universe’s fundamental ingredients, or some aspect of how those ingredients stir together.

Now a second crack in the so-called standard model of cosmology may be forming.

New Hubble data suggests there is an ingredient missing from current dark matter theories

Recent observations have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why researchers have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters.

How Did The Universe Make Our Existence Possible?

From the largest cosmic scales down to the smallest subatomic ones, the same laws of physics define the entire Universe. The building blocks from which life arose on Earth weren't something that the Universe was born with, but rather needed to be created, astrophysically, over cosmic timescales.

We can learn a lot about the history of the Universe just by looking at each of our own bodies. A fully grown adult human is an incredibly complex system, made up of trillions of cells and somewhere in the neighborhood of 1028 atoms: the building blocks of all matter on Earth. The scientific story of what it takes to make a human teaches us an enormous about about not only the evolution and history of life on Earth, but of the entire Universe as well. Continue to read

This is Your Brain. This is Your Brain as a Weapon

Cutting-edge neural technologies can erase traumatic memories and read people’s thoughts. They could also become the 21st century’s next battleground.
On an otherwise routine July day, inside a laboratory at Duke University, two rhesus monkeys sat in separate rooms, each watching a computer screen that featured an image of a virtual arm in two-dimensional space. The monkeys' task was to guide the arm from the center of the screen to a target, and when they did so successfully, the researchers rewarded them with sips of juice.

But there was a twist. The monkeys were not provided with joysticks or any other devices that could manipulate the arm. Rather, they were relying on electrodes implanted in portions of their brains that influence movement. The electrodes were able to capture and transmit neural activity through a wired connection to the computers.

Making things even more interesting, the primates shared control over the digital limb. Continue to read

That’s not our Moon, that’s Dwarf planet Ceres. The largest object in the asteroid belt between Mars and Jupiter and the only dwarf planet located in the inner solar system. It was the first member of the asteroid belt to be discovered when Giuseppe Piazzi spotted it in 1801. And when Dawn arrived in 2015, Ceres became the first dwarf planet to receive a visit from a spacecraft.

Water on Mars: discovery of three buried lakes intrigues scientists


Two years ago, planetary scientists reported the discovery of a large saltwater lake under the ice at Mars’s south pole, a finding that was met with excitement and some scepticism. Now, researchers have confirmed the presence of that lake — and found three more.

The discovery, reported on 28 September in Nature Astronomy1, was made using radar data from the European Space Agency’s Mars-orbiting spacecraft, called Mars Express. It follows the detection of a single subsurface lake in the same region in 2018 — which, if confirmed, would be the first body of liquid water ever detected on the red planet and a possible habitat for life. But that finding was based on just 29 observations made from 2012 to 2015, and many researchers said they needed more evidence to support the claim. The latest study used a broader data set comprising 134 observations from 2012 to 2019.
