Scientists Observe Year-long Plateaus in Decline of Type Ia Supernova Light Curves
A team of scientists, including a researcher from the University of Birmingham, has discovered that the fading of infrared light following Type Ia supernovae explosions can be interrupted, with brightness staying the same for up to a year. This is a surprising finding as astronomers had expected that the light curve would not only continue decreasing but even experience a sharp drop, rather than flattening into a plateau.

’Picoscience’ and a plethora of new materials
The revolutionary tech discoveries of the next few decades, the ones that will change daily life, may come from new materials so small they make nanomaterials look like lumpy behemoths. These new materials will be designed and refined at the picometer scale, which is a thousand times smaller than a nanometer and a million times smaller than a micrometer (which itself is smaller than the width of a human hair).

Quantum Vacuum: Less than Zero Energy
Quantum Vacuum: Less than Zero Energy
Is it possible to borrow energy from an empty space? And if yes, do we have to give it back? Energy values smaller than zero are allowed - at least within certain limits. Energy is a quantity that must always be positive - at least that's what our intuition tells us. If every single particle is removed from a certain volume until there is nothing left that could possibly carry energy, then a limit has been reached.

A metronome for quantum particles
A new measurement protocol, developed at TU Wien (Vienna), makes it possible to measure the quantum phase of electrons - an important step for attosecond physics. It is like a microscope for time: Today's methods of attosecond physic allows us to measure extremely short time intervals. With the help of short laser pulses, physical processes can be investigated on a time scale of attoseconds - that is billionths of a billionth of a second.

Quantum material goes where none have gone before ?
Alloy behaves strangely while traversing potential 'spin liquid' state Rice University physicist Qimiao Si began mapping quantum criticality more than a decade ago, and he's finally found a traveler that can traverse the final frontier. The traveler is an alloy of cerium palladium and aluminum, and its journey is described in a study published online this week by Si, a theoretical physicist and director of the Rice Center for Quantum Materials (RCQM), and colleagues in China, Germany and Japan.

Growing old together: a sharper look at black holes and their host galaxies
Some relationships are written in the stars. That's definitely the case for supermassive black holes and their host galaxies, according to a new study from Yale University. The "special relationship" between supermassive black holes (SMBHs) and their hosts - something astronomers and physicists have observed for quite a while - can now be understood as a bond that begins early in a galaxy's formation and has a say in how both the galaxy and the SMBH at its center grow over time, the researchers note.
