Ordering of atoms in liquid gallium under pressure
Ordering of atoms in liquid gallium under pressure
Liquid metals and alloys have exceptional properties that make them suitable for electrical energy storage and generation applications. Low-melting point gallium-based liquid metals are used as heat exchange fluids for cooling integrated electronics and in the manufacture of flexible and reconfigurable electronic devices and soft robotics.

Risk aversion as a survival strategy in ants
Risk aversion as a survival strategy in ants
Ants are excellent navigators and always find their way back to the nest. But how do they react when an obstacle or a predator blocks their path? An international team including Antoine Wystrach, a CNRS researcher at the Research Centre on Animal Cognition (CNRS/Université Tou-louse III - Paul Sabatier), has shown that ants are capable of changing their familiar route to avoid traps thanks to an aversive learning mechanism: by associating visual cues with negative experiences, they can memorise potentially dangerous routes.

Neanderthal cord weaver
Neanderthal cord weaver
Contrary to popular belief, Neanderthals were no less technologically advanced than Homo sapiens . An international team, including researchers from the CNRS, have discovered the first evidence of cord making, dating back more than 40,000 years 1 , on aflint fragment from the prehistoric site of Abri du Maras in the south of France 2 .

World's most complex microparticle: A synthetic that outdoes nature's intricacy
World’s most complex microparticle: A synthetic that outdoes nature’s intricacy
Synthetic microparticles more intricate than some of the most complicated ones found in nature have been produced by a University of Michigan-led international team. They also investigated how that intricacy arises and devised a way to measure it. The findings pave the way for more stable fluid-and-particle mixes, such as paints, and new ways to twist light-a prerequisite for holographic projectors.

Center for Astrophysics Scientist and Team First to Measure Wind Speed on an Object Outside the Solar System
Harvard & Smithsonian-today announced the first measurement of atmospheric wind speed ever recorded outside the solar system using a novel technique. Researchers focused their efforts on 2MASS J1047+21, a cool brown dwarf located 33.2 light years from Earth, and clocked wind speeds at 650 meters per second, or 1,450 miles per hour.

Researchers develop new coronavirus test for frontline NHS workers
A new test for infection with SARS-CoV2 that which inactivates the virus at the point of sampling, has been developed by a team of researchers at the Cambridge Institute for Therapeutic Immunology and Infectious Disease (CITIID). It is now being used to test and screen frontline NHS staff at a Cambridge hospital.

Fine-Tuning Magnetic Spin for Faster, Smaller Memory Devices
Fine-Tuning Magnetic Spin for Faster, Smaller Memory Devices
Unlike the magnetic materials used to make a typical memory device, antiferromagnets won't stick to your fridge. That's because the magnetic spins in antiferromagnets are oppositely aligned and cancel each other out. Scientists have long theorized that antiferromagnets have potential as materials for ultrafast stable memories.

3D printed corals could improve bioenergy and help coral reefs
Researchers have designed bionic 3D-printed corals that could help energy production and coral reef research. We hope that our technique will be scalable so it can ultimately reduce greenhouse gas emissions that are responsible for coral reef death Daniel Wangpraseurt Researchers from Cambridge University and University of California San Diego have 3D printed coral-inspired structures that are capable of growing dense populations of microscopic algae.

COVID-19: genetic network analysis provides 'snapshot' of pandemic origins
COVID-19: genetic network analysis provides ’snapshot’ of pandemic origins
Study charts the "incipient supernova" of COVID-19 through genetic mutations as it spread from China and Asia to Australia, Europe and North America. Researchers say their methods could be used to help identify undocumented infection sources.   Phylogenetic network analysis has the potential to help identify undocumented COVID-19 infection sources Peter Forster Researchers from Cambridge, UK, and Germany have reconstructed the early "evolutionary paths" of COVID-19 in humans - as infection spread from Wuhan out to Europe and North America - using genetic network techniques.

Launched to understand mental health implications of COVID-19
Study launched to understand mental health implications of COVID-19 The University of Glasgow is leading a new study, in partnership with Samaritans and SAMH (Scottish Association for Mental Health), into the mental health and wellbeing effects of the COVID-19 pandemic in adults across the UK. The study will aim to understand the impact of the pandemic, and the unprecedented social distancing measures introduced across the country, on mental health indicators such as anxiety, depression, loneliness, self-harm or positive mental wellbeing.

’Freeze frame’ chemistry to unlock drugs of the future
Researchers are taking snapshots of chemical reactions in a trillionth of a second in the hope of developing the next generation of antibiotics and anti-viral drugs. Using state-of-the-art laser technology, scientists at Cardiff University and the Rosalind Franklin Institute are creating ‘freeze frame movies' of chemical reactions, with a starring role for a specific enzyme that could be used to make new drugs that are active against viruses, such as COVID-19.

Bristol leads archaeologists on 5,000-year-old egg hunt
Bristol leads archaeologists on 5,000-year-old egg hunt
Long before Fabergé, ornate ostrich eggs were highly prized by the elites of Mediterranean civilisations during the Bronze and Iron Ages, but to date little has been known about the complex supply chain behind these luxury goods. Examining ostrich eggs from the British Museum's collection, the team, led by Bristol's Dr Tamar Hodos , were able to reveal secrets about their origin and how and where they were made.

Vexing Nemo: motorboat noise makes clownfish stressed and aggressive
Vexing Nemo: motorboat noise makes clownfish stressed and aggressive
Working on the reefs around Moorea in French Polynesia, an international team of scientists exposed 40 pairs of clownfish to recordings of natural reef sounds or motorboat noise for up to two days. Motorboat noise caused clownfish to hide in the protective tentacles of their host anemone, move less into open water to feed and to be more aggressive towards domino damselfish that also reside in the anemone.

Kids or teen smokers are less likely to kick the habit as adults
A new study from the University of Minnesota  School of Public Health (SPH) and its international partners found that the younger people start smoking, the more likely they are to smoke daily as an adult, even into their 40s, and the harder it will be to quit. Their findings were recently published in the Journal of the American Heart Association.  Researchers analyzed smoking information on more than 6,600 people (57% female) between the ages of 6-19 and during their 20s and 40s, from Finland, Australia and the United States.

Agriculture began in the Amazon 10’000 years ago
As a new study shows, more than 10,000 years ago, people in the southwest of the Amazon began growing manioc and squash, 8,000 years earlier than previously thought. The area is thus one of the early Holocene centres of plant domestication in the world. People also changed the landscape by creating thousands of so-called forest islands.
