Physicists Further Narrow Down Range of Search for Dark Matter

In the 21st century, the search for dark matter is one of the most fascinating challenges in fundamental physics. For a long time, scientists have been aware that it does exist, as it would have otherwise been hard to explain numerous astrophysical observations.

Scientists Discover the Presence of Axions in Weyl Semimetal

Researchers from the Max Planck Institute for Chemical Physics of Solids in Dresden, Princeton University, the University of the Chinese Academy of Sciences, and the University of Illinois at Urbana-Champaign have discovered a prominently elusive particle—the axion.

Not Long Ago, the Centre of the Milky Way Exploded

Researchers find evidence of a cataclysmic flare that punched so far out of the Galaxy its impact was felt 200,000 light years away.

This is How a “Fuzzy” Universe May Have Looked

Dark matter was likely the starting ingredient for brewing up the very first galaxies in the universe. Shortly after the Big Bang, particles of dark matter would have clumped together in gravitational “halos,” pulling surrounding gas into their cores, which over time cooled and condensed into the first galaxies.

A Filament Fit for Space - Silk is Proven to Thrive in Outer Space Temperatures

Scientists from the universities of Oxford, Shanghai and Beijing who discovered that natural silks get stronger the colder they get, have finally solved the puzzle of why. Their initial discovery had seemed like a contradiction because most other polymer fibres embrittle in the cold.

Study of Genuine 2D Effects Starting from a Single 1D Wire

Restriction of movement of quantum particles to one, two, or three dimensions has resulted in the observation of several striking phenomena. An ideal example is the quantization of the Hall conductance recorded in 2D materials in the presence of a strong magnetic field.

Scientists Report New Method for Electrical Cooling Using Quantum Wells

Scientists at the University of Tokyo have reported a new method for electrical cooling that can be executed even in the absence of moving parts. When a bias voltage is applied to quantum wells made of aluminum gallium arsenide, a semiconductor, electrons release some of their heat by a process known as “evaporative cooling.”
