Search for heavy bosons sets new limits

Since discovering the Higgs boson in 2012, the ATLAS Collaboration at CERN has been working to understand its properties. One question in particular stands out: why does the Higgs boson have the mass that it does? Experiments have measured its mass to be around 125 GeV—yet the Standard Model implies it has much larger mass and requires a very large correction to the mathematics in order to align theory with observation, leading to the "naturalness problem."

The Future of Satellites Lies in the Constellations

Numerous companies are planning to launch and operate swarms of small satellites in coming years. Earth orbit is about to get crowded.

Remembering the Crew of Soyuz 11, the Only Astronauts to Die in Space

The ill-fated replacement crew of Soyuz 11 spent three weeks performing experiments on the world's first space station. But their return trip ended in tragedy.

A new piece of the quantum computing puzzle

Scientists have developed a groundbreaking quantum logic gate that brings quantum computing closer to reality.

Hunting dark energy with gravity resonance spectroscopy

Dark Energy is widely believed to be the driving force behind the universe's accelerating expansion, and several theories have now been proposed to explain its elusive nature. However, these theories predict that its influence on quantum scales must be vanishingly small, and experiments so far have not been accurate enough to either verify or discredit them. In new research published in EPJ ST, a team led by Hartmut Abele at TU Wien in Austria demonstrates a robust experimental technique for studying one such theory, using ultra-cold neutrons.

How an Obscure Underwater Lab Has Influenced Sea Research and Space Exploration

Florida's 30-year-old Aquarius Reef Base has housed hundreds of ocean researchers, divers and NASA crews preparing for space, for days on end.

New 2D alloy combines five metals, breaks down CO2

A new, two-dimensional material has been synthesized to act as a catalyst for reducing CO2, into CO, with potential applications in environmental remediation.

Polymers in meteorites provide clues to early solar system

Meteorites that do not experience high temperatures at any point in their existence provide a good record of complex chemistry present when or before our solar system was formed. So researchers have examined individual amino acids in these meteorites, many of which are not in present-day organisms. Researchers now show the existence of a systematic group of amino acid polymers across several members of the oldest meteorite class, the CV3 type.

Identifying a topological fingerprint

Australian theoretical physics study just out has identified a 'smoking gun' in long search for the topological magnetic monopole referred to as the Berry curvature. This breakthrough in search for topological effects in non-equilibrium systems opens paths towards low-energy topological electronics viable for large-scale, room-temperature operation.

This crystal impurity is sheer perfection

Scientists have developed a nanoparticle composite that grows into 3D crystals. The new 3D-grown material could speed up production and eliminate errors in the mass manufacturing of nanoscale photonics for smart buildings or actuators for robotics.
