A Physicist Just Explained Why the Large Hadron Collider Disproves the Existence of Ghosts

Recent polls have found that 42 percent of Americans and 52 percent of people in the UK believe in ghosts - a huge percentage when you consider that no one has ever come up with irrefutable proof that they even exist.

But we might have had proof that they don't exist all along, because as British theoretical physicist Brian Cox recently pointed out, there's no room in the Standard Model of Physics for a substance or medium that can carry on our information after death, and yet go undetected in the Large Hadron Collider.

The Blood of Komodo Dragons Could Help Us to Slay Antibiotic Resistance

Protein fragments in the blood of Komodo dragons have antimicrobial properties that help them resist toxic bacteria, and they could be used to develop new drugs to counter antibiotic resistance, researchers have found.

The Komodo dragon is the world's largest lizard, growing up to 3 metres (9.8 feet) in length and weighing up to 70 kilograms (154 lbs). It lives on five small islands in Indonesia, where its massive size and sharp teeth enable it to feast on prey as large as water buffalo – but there's another, less obvious reason why you definitely don't want to get bitten by one.

This Is What Earth's Magnetic Field Sounds Like

The ancients believed that Earth was surrounded by celestial spheres, which produced divine music when they moved. We lived, so to speak, in a huge musical instrument.

This may sound silly but modern science has proved them right to a certain extent. Satellites recording sound waves resonating with Earth's magnetosphere – the magnetic bubble that protects us from space radiation – show that we are indeed living inside a massive, magnetic musical instrument.

Tiny 'MoonWatcher' Satellite Will Beam Home Live Lunar Views

Soon, a tiny satellite will start beaming home live, high-resolution views of the moon for all the world to see, 24 hours a day, if all goes according to plan.

The startup Lunar Station aims to launch a cubesat called MoonWatcher to Earth orbit early next year and then air webcasts based on the spacecraft's sharp imagery. The company has launched a Kickstarter campaign to help fund the effort and hopes to raise $150,000 by March 12.

Physicists Have Detected a Friction-Like Force in a Perfect Vacuum

One of the most fundamental tenets of modern physics is that in a perfect vacuum - a place entirely devoid of matter - no friction can possibly exist, because empty space cannot exert a force on objects travelling through it.

But despite the conventional wisdom, physicists in the UK discovered that a decaying atom travelling through a complete vacuum would experience a friction-like force, and now they've figured out how this reinforces - rather than breaks - Einstein's theory of general relativity.

A Giant Neuron Has Been Found Wrapped Around the Entire Circumference of the Brain

For the first time, scientists have detected a giant neuron wrapped around the entire circumference of a mouse's brain, and it's so densely connected across both hemispheres, it could finally explain the origins of consciousness.

Using a new imaging technique, the team detected the giant neuron emanating from one of the best-connected regions in the brain, and say it could be coordinating signals from different areas to create conscious thought.

Scientists Have Found a Way to Rapidly Thaw Cryopreserved Tissue Without Damage

Researchers have developed a technique that allows them to rapidly thaw cryopreserved human and pig samples without damaging the tissue - a development that could help get rid of organ transplant waiting lists.

Cryopreservation is the ability to preserve tissues at liquid nitrogen temperatures for long periods of time and bring them back without damage, and it's something scientists have been dreaming about achieving with large tissue samples and organs for decades.

Not only for the life-extending applications we've read about in sci-fi novels, but, more feasibly, because the technology could allow hospitals to safely store organs for long periods of time.

DNA could be the future of data storage

The world is churning out so much data that hard-drives may not be able to keep up, leading researchers to look at DNA as a possible storage medium. DNA is ultra compact, and doesn’t degrade over time like cassettes and CDs. In a new study, Yaniv Erlich and Dina Zielinski demonstrate DNA’s full potential and reliability for storing data. The researchers wrote six files—a full computer operating system, a 1895 French film, an Amazon gift card, a computer virus, a Pioneer plaque, and a study by information theorist Claude Shannon—into 72,000 DNA strands, each 200 bases long. They then used sequencing technology to retrieve the data, and software to translate the genetic code back into binary. The files were recovered with no errors. We spoke with Erlich about the results, and what they mean for the future of data storage.

First hint of how DNA calculators could supercharge computing

By making DNA endlessly change, researchers have shown how a biological computer might one day solve problems much faster than conventional computers or even quantum computers. It’s still a long way from being functional though.

The DNA-based system is an experiment in how it may be possible to make a theoretical type of computer known as a non-deterministic universal Turing machine.

Such a machine could solve tricky problems much faster than existing computers. Imagine that a computer is trying to find the centre of a maze and has a choice between left and right. A conventional computer would turn in one direction and follow that path to the end, then try a different route if that one leads nowhere.

But a non-deterministic universal Turing machine would explore both paths simultaneously, and do so again every time the path splits until it has found the right route to the maze’s heart.

First Solid Sign that Matter Doesn't Behave Like Antimatter

One of the biggest mysteries in physics is why there's matter in the universe at all. This week, a group of physicists at the world's largest atom smasher, the Large Hadron Collider, might be closer to an answer: They found that particles in the same family as the protons and neutrons that make up familiar objects behave in a slightly different way from their antimatter counterparts.

NASA Considers Magnetic Shield to Help Mars Grow Its Atmosphere

The Planetary Science Vision 2050 Workshop is happening right now at NASA headquarters in Washington DC. The workshop is meant to discuss ambitious space projects that could be realized, or at least started, by 2050.

One of the most enticing ideas came this morning from Jim Green, NASA's Planetary Science Division Director. In a talk titled, "A Future Mars Environment for Science and Exploration," Green discussed launching a "magnetic shield" to a stable orbit between Mars and the sun, called Mars L1, to shield the planet from high-energy solar particles. The shield structure would consist of a large dipole—a closed electric circuit powerful enough to generate an artificial magnetic field.

To advance science we need to think about the impossible

HOW does science advance? The number of papers published annually doubled every 9 years in the second half of the 20th century; the number of working scientists now doubles roughly every 18 years. So we might expect science today to be advancing at a breakneck pace. And so it is, but in a great many small steps, rather than giant leaps of understanding.

That’s fine: science has always advanced in small steps, paving the way for occasional leaps. But sometimes fact-collecting yields nothing more than a collection of facts; no revelation follows. At such times, we need to step back from the facts we know and imagine alternatives: in other words, to ask “what if?”
