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 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.

Can the conflict between dark matter and gravity be resolved?

Can the conflict between dark matter and gravity be resolved? To date, we’ve accounted for this by invoking dark matter and dark energy, which together apparently make up much of the universe.Epicycles accounted for everything we could see — until suddenly we could see more, and that explanation was no longer sufficient.

Extreme science: the biggest, fastest and hottest breakthroughs of 2016

Extreme science: the biggest, fastest and hottest breakthroughs of 2016 Where LCLS-II is like a microscope, used to image specific tiny things, proton colliders like the LHC are closer to sledgehammers.Remember that photons and electrons have both wavelike and particle-like properties, and they both have the mass-related property of momentum.

Researchers claim they compressed hydrogen into a metallic state

Researchers claim they compressed hydrogen into a metallic state If it exists, metallic hydrogen could fundamentally transform the way we used energy.Now, two scientists claim they’ve successfully created solid metallic hydrogen, but the scientific community is not yet convinced.

Optical shock: Scientists have imaged light going faster than itself

Optical shock: Scientists have imaged light going faster than itself Louis has taken images of a laser pulse generating an optical Mach cone: the equivalent of a sonic boom, but for light.To make an optical Mach cone, a pulse of light would need to be traveling faster than the waves it’s emitting can propagate forward.

Explosions used to make large quantities of graphene

Explosions used to make large quantities of graphene The problem is that graphene is incredibly difficult to make, but researchers at Kansas State University (KSU) might have stumbled upon a solution.The KSU team was working on creating carbon soot aerosol gels with combustion.

Scientists finally make 'triangulene,' which is good, we think

Scientists finally make 'triangulene,' which is good, we think On paper, triangulene is made of six benzene rings, put together edge-on to make a flat triangular flake of a molecule that has a seemingly innocuous set of unpaired electrons.The icing on the proverbial cake is that the scientists who made triangulene have no idea how to handle it nor what to do with it.

The only sample of metallic hydrogen on Earth has vanished

The only sample of metallic hydrogen on Earth has vanished The physics world was abuzz with excitement (and skepticism) last month when scientists from Harvard University claimed they had created a stable sample of metallic hydrogen.As the name implies, metallic hydrogen is a solid form of hydrogen with properties like a metal.

The Newly Discovered TRAPPIST-1 Star System Was Hiding In Elite: Dangerous All Along

The Newly Discovered TRAPPIST-1 Star System Was Hiding In Elite: Dangerous All Along Now, it turns out that Elite: Dangerous actually predicted the existence of the TRAPPIST-1 star system where they’re located.Using some of the leftover “unaccounted mass,” the game, unprompted, created a star system very much like TRAPPIST-1.
