Sound waves let quantum systems ’talk’ to one another
Researchers at the University of Chicago and Argonne National Laboratory have invented an innovative way for different types of quantum technology to "talk" to each other using sound. The study , published Feb. 11 , is an important step in bringing quantum technology closer to reality. Researchers are eyeing quantum systems, which tap the quirky behavior of the smallest particles as the key to a fundamentally new generation of atomic-scale electronics for computation and communication.

What makes a man? Testosterone only half the story, scientists say
Scientists have identified for the first time the details of an ‘alternative' biological process required to develop male genitals in an unborn baby. The findings by researchers at the universities of Aberdeen and Glasgow along with French and Swedish collaborators also sheds more light on the reasons for babies being born with undescended testes or with malformed penises.

Tidal Tails - The Beginning Of The End Of An Open Star Cluster
Tidal Tails - The Beginning Of The End Of An Open Star Cluster
In the course of their life, open star clusters continuously lose stars to their surroundings. The resulting swath of tidal tails provides a glimpse into the evolution and dissolution of a star cluster. Thus far only tidal tails of massive globular clusters and dwarf galaxies have been discovered in the Milky Way system.

Live better with attainable goals
Live better with attainable goals
Those who set realistic goals can hope for a higher level of well-being. The key for later satisfaction is whether the life goals are seen as attainable and what they mean to the person, as psychologists from the University of Basel report in a study with over 970 participants. Wealth, community, health, meaningful work: life goals express a person's character, as they determine behavior and the compass by which people are guided.

High success rate for hip and knee replacements
High success rate for hip and knee replacements
After reviewing thousands of case studies going back 25 years across six countries, generalisable survival data is now available for the first time to estimate how long hip and knee replacements are likely to last. The findings of researchers, funded by the National Joint Registry , from the Musculoskeletal Research Unit at the University of Bristol have been published in The Lancet .

Explains how rabbits adapted to survive myxomatosis
An unprecedented study of rabbit DNA spanning 150 years and thousands of miles has revealed the genetic basis for the animal's fightback - and ultimate triumph, against the deadly myxoma virus. The revelation of how rabbits evolved genetic resistance to myxomatosis through natural selection, comes as part of an international research collaboration, nearly seventy years after the lethal disease decimated species' populations of Australia, Britain and France.

New Molecular Blueprint Advances Our Understanding of Photosynthesis
New Molecular Blueprint Advances Our Understanding of Photosynthesis
Berkeley Lab research will shed light on the process by which plants convert carbon dioxide into sugar, helping scientists engineer crops that produce sustainable bioproducts including biofuels. Researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have used one of the most advanced microscopes in the world to reveal the structure of a large protein complex crucial to photosynthesis, the process by which plants convert sunlight into cellular energy.

Ers create ultra-lightweight ceramic material that can better withstand extreme temperatures
UCLA-led team develops highly durable aerogel that could ultimately be an upgrade for insulation on spacecraft Matthew Chin UCLA researchers and collaborators at eight other research institutions have created an extremely light, very durable ceramic aerogel. The material could be used for applications like insulating spacecraft because it can withstand the intense heat and severe temperature changes that space missions endure.

Cannabis use in teens raises risk of depression in young adults
Cannabis use in teens raises risk of depression in young adults
Cannabis use among adolescents is found to be associated with increased risk of depression and anxiety in adulthood. Cannabis is the most commonly used recreational drug by teenagers worldwide. In Canada, among youth aged 15 to 19 years, the rate of past-year cannabis use is 20.6%, while in England, 4% of adolescents aged 11 to 15 years used cannabis in the last month.

Where is the Universe Hiding its Missing Mass?
Astronomers have spent decades looking for something that sounds like it would be hard to miss: about a third of the "normal" matter in the Universe. New results from NASA's Chandra X-ray Observatory may have helped them locate this elusive expanse of missing matter. From independent, well-established observations, scientists have confidently calculated how much normal matter - meaning hydrogen, helium and other elements - existed just after the Big Bang.

Solar-powered supercapacitors could create flexible, wearable electronics
A breakthrough in energy storage technology could bring a new generation of flexible electronic devices to life, including solar-powered prosthetics for amputees. In a new paper published in the journal Advanced Science , a team of engineers from the University of Glasgow discuss how they have used layers of graphene and polyurethane to create a flexible supercapacitor which can generate power from the sun and store excess energy for later use.

Satellite images reveal interconnected plumbing system that caused Bali volcano to erupt
A team of scientists, led by the University of Bristol, has used satellite technology provided by the European Space Agency (ESA) to uncover why the Agung volcano in Bali erupted in November 2017 after 50 years of dormancy. Their findings, published today , could have important implications for forecasting future eruptions in the area.

Media and industry not always interested in the same topics
Hardly a day went by in the summer of 2018 without a report on the continuing water scarcity at the time in Switzerland. Again and again, newspapers, radio and television were coming up with questions like: "How much water do nature, agriculture and people need?", "How can we find ways to save water?" and "Which regions have the least water reserves?" On the other hand, Swiss municipal governments, cantons, engineering firms, NGOs and public sector agencies appear to be less concerned with the relationship between water scarcity and water-saving measures.

The lizard and the egg: lizards break golden rule of biology
Researchers at The Australian National University (ANU) have made a remarkable discovery about a group of lizards, and how they've managed to thrive in extreme conditions on one of the world's highest mountain ranges. The Liolaemus lizards - found mainly around South America's Andes Mountains - reproduce in a way that challenges one of biology's best known rules, Dollo's Law.

Earth’s atmosphere stretches out to the Moon - and beyond
The outermost part of our planet's atmosphere extends well beyond the lunar orbit - almost twice the distance to the Moon. A recent discovery based on observations by the ESA/NASA Solar and Heliospheric Observatory, SOHO, shows that the gaseous layer that wraps around Earth reaches up to 630 000 km away, or 50 times the diameter of our planet.

Giving keener "electric eyesight" to autonomous vehicles
On-chip system that detects signals at sub-terahertz wavelengths could help steer driverless cars through fog and dust. Autonomous vehicles relying on light-based image sensors often struggle to see through blinding conditions, such as fog. But MIT researchers have developed a sub-terahertz-radiation receiving system that could help steer driverless cars when traditional methods fail.

More older people with depression could benefit from non-drug treatments
Depression is common in older age and with an ageing population how late-life depression is managed will become increasingly important. Researchers from the University of Bristol and University College London (UCL) suggest mental health in later life should be given greater priority by healthcare professionals.
