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.”

Study on the Violent History of Andromeda Galaxy

An international team of galactic investigators has put together the intense history of the Andromeda galaxy, which is now looking at the Milky Way as its next victim.

Quantum Vacuum is More Complicated than Previously Believed

Energy can be described as a quantity that should constantly remain positive—at least that is what people’s intuition tells them.

The Possible Application of Spintronics in Modern Electronics

3D structures are currently being studied in order to boost the efficiency of microchips. However, spintronic components, which depend on electron spin instead of charge, are constantly flat.

Physicist Maps Quantum Criticality Where Electrons Follow Different Sets of Rules

Qimiao Si, a theoretical physicist at Rice University, has been mapping quantum criticality for more than 10 years. Now, he has finally identified a traveler that can cross the ultimate frontier.

Researchers Detect Fundamental Nucleobases in Simulated Interstellar Cloud

An experiment has revealed that nucleobases could have formed inside giant gas clouds interspersed between the stars. Nucleobases are one of the fundamental units of life.
