New particle collider can smash electrons into ‘holes’

New particle collider can smash electrons into ‘holes’ There are colliders that smash together special types of particles, or which smash together particles using only a specific type of controlling energy.But now, a team of German scientists has published a study in Nature describing their new form of collider, which can smash so-called “quasiparticles” together.

Science may be close to understanding where heavy elements come from

Science may be close to understanding where heavy elements come from It seems so simple: where do the elements come from?Signals collected from the brightest stars in a tiny galaxy called Reticulum II show far higher concentrations of heavy elements than theorized.

The universe is expanding even faster than we thought

The universe is expanding even faster than we thought The universe is a very big place, and science has proven that it’s only getting bigger as time goes on.Based on the newly published data, it’s happening even faster than we thought.

Gravitational wave science gets go-ahead to revolutionize astronomy

Let’s be honest: while the recently announced proof of the existence of gravitational waves was undeniably an enormous, exciting moment for science, it didn’t really accomplish much all on its own.It’s important that scientists have proven the existence of gravitational waves — but not in the least bit surprising.

Scientists could get first ever image of a black hole in 2017

Despite all the depictions of black holes in science fiction movies and TV, scientists have never actually seen one.Even the largest black holes scientists have located are still very obscured and distant.

This quantum ruler is the latest win against the many ‘nevers’ of quantum science

Its wavelengths, as we were able to create and use them, were in many cases too large for our purposes — even in the smallest range.Yet today, high-level quantum experiments regularly use entanglement as a tool to make even larger discoveries.

Why gravitational wave detection may have also revealed dark matter

These would be very large for primordial black holes, but technically allowable based on preexisting model for their creation.What this means is not only that gravitational wave detectors could be used to investigate the nature of dark matter, via investigating these black holes, but that gravitational wave detectors already have investigated dark matter.

Data stored at the atomic level with super-high density

Data stored at the atomic level with super-high density Researchers from Delft University of Technology in the Netherlands have devised a way to store data on the atomic scale by manipulating single atoms.The density of the proof-of-concept atomic storage created for the study is 500 terabytes per square inch.

This is your brain on physics: Scientists figure out how humans learn abstract concepts

This is your brain on physics: Scientists figure out how humans learn abstract concepts Scientists from CMU report that the brain handles scientific abstractions “using inherent, re-purposed brain systems,” according to Robert Mason, coauthor of their latest study.Then they fed those brain scans into a machine learning model, and found that the brain lit up in certain places in response to certain physics concepts, regardless of which person was doing the contemplating.

Scientists isolate the brain’s ‘physics engine,’ could lead to faster, more agile robots

Scientists isolate the brain’s ‘physics engine,’ could lead to faster, more agile robots Now, for the first time, Johns Hopkins scientists have located the part of the brain responsible for this basic, fundamental processing.These brain regions are also part of the multiple demand network, a widespread set of functional areas.

An ‘acoustic prism’ can split sound the way a regular prism splits light

An ‘acoustic prism’ can split sound the way a regular prism splits light Here’s a new invention that, while potentially useful, is even more interesting as an illustration of the nature of sound: the acoustic prism.Now, researchers have created a similar device for sound, which passively and naturally splits sounds into their component frequencies.

Scientists are closing in on turning hydrogen into a metal

Scientists are closing in on turning hydrogen into a metal This isn’t about making lead into gold, but turning elemental hydrogen into a different, never before seen form of hydrogen.Scientists are tantalizingly close to producing the first samples of solid metallic hydrogen using powerful lasers, electrical impulses, and other cutting edge equipment.

The so-called fifth force of nature is starting to look more and more real

The so-called fifth force of nature is starting to look more and more real They found that this new particle should be about 30 times heavier than an electron, or about 17 MeV (megaelectronvolts).Such a dark force would be useful in revealing the nature of WIMPs, the theorized mass-carrying particle that makes up dark matter.

Scientists create liquid light, get one step closer to spintronics

Scientists create liquid light, get one step closer to spintronics “We have made a field-effect light switch that can bridge the gap between optics and electronics,” says Dr.“We’re reaching the limits of how small we can make transistors, and electronics based on liquid light could be a way of increasing the power and efficiency of the electronics we rely on.

Astronomers observed a nova explosion for the first time by accident

Astronomers observed a nova explosion for the first time by accident For the first time, a team of scientists have captured all phases of a classical nova explosion — before, during, and after the event.Our sun will most likely become a white dwarf at the end of its life.

Scientists develop a memristor that can be conditioned just like a real synapse

Scientists develop a memristor that can be conditioned just like a real synapse The memristor is made of a silicon-oxygen-nitrogen material laced with clumps of silver nanoparticles at the electrical terminals.When current is applied across the memristor, the silver nanoparticles shuffle around within their parent oxynitride matrix, to line up within a lightning-bolt-like path of least electrical resistance.

The 2016 Nobel Prize in Physics goes to mathematicians working in Flatland

The 2016 Nobel Prize in Physics goes to mathematicians working in Flatland Michael Kosterlitz for “theoretical discoveries of topological phase transitions and topological phases of matter.When cooled to just a few degrees above absolute zero, and subjected to a perpendicular magnetic field of 15 Tesla (just barely weaker than the magnetic field required to levitate a frog), that conductive 2D layer started acting very differently.

Oxford scientists call into question the idea that the universe’s expansion is accelerating

Oxford scientists call into question the idea that the universe’s expansion is accelerating Type Ia supernovae are affectionately called “standard candles” in astronomy.When the Oxford team did their own analysis of the universe’s expansion scenarios, their best-case, most-certain outcome was much less confident that the universe is expanding at an accelerating rate.

Oxford scientists call into question the idea that the universe's expansion is accelerating

Oxford scientists call into question the idea that the universe's expansion is accelerating When the Oxford team did their own analysis of the universe’s expansion scenarios, their best-case, most-certain outcome was much less confident that the universe is expanding at an accelerating rate.Instead, the data “lends itself” to the conclusion that the rate of expansion is constant.

LIGO's black hole detection survives the gravatstar test

LIGO's black hole detection survives the gravatstar test The original idea was that the first confirmed detection of gravitational waves was the result of a binary black hole event: two black holes meeting in space, spiraling inward, and eventually merging.Now, a new test has examined the idea that what LIGO actually saw was not the merger of two black holes, but the merger of two gravastars.
