Phys.org / Climate change is now causing more local extinction in temperate regions than the tropics, study shows
Imagine returning to a favorite hiking trail 15 years after your first visit and discovering that many of the plants and animals that once lived there are gone. While these species may still exist elsewhere, these disappearances—known ...
Phys.org / How to train your magnet: Excitons as a new knob for magnetic control
Scientists can learn a lot about a quantum material by watching how it responds to light. In magnetic semiconductors, one especially useful messenger is the exciton: a pairing of a negatively charged electron and the positively ...
Phys.org / Medieval Moroccan bathhouse steps reveal rare game board
Archaeologists have discovered a game board carved into the steps of a medieval bathhouse in the Moroccan town of Walīla (the Roman city of Volubilis). The find is a rare example of a medieval game board that can be securely ...
Medical Xpress / Chewing sugary gum may enhance the cardiovascular benefits of nitrate-rich vegetables
For the first time, researchers at King's College London have discovered a link between chewing sugary gum after consuming vegetables high in nitrate, such as beetroot, spinach and kale, and lowering blood pressure. The study ...
Phys.org / What if there is no one to farm? Scientists reveal a hidden risk to future food security
The cause of future food shortages may not be a lack of farmland, but a shortage of agricultural workers. Amid low birth rates and rural decline, a joint international research team from KAIST has developed a new data-driven ...
Phys.org / Long gamma-ray bursts may trace collapsing stars rather than neutron-star mergers
Long-duration gamma-ray bursts are some of the most energetic events in the universe, releasing more energy in just a few seconds than the sun emits in 10 billion years. Los Alamos National Laboratory scientists, having discovered ...
Phys.org / Famous 'Pink Planet' harbors a salty surprise
Northwestern University-led astronomers have discovered salty skies surrounding the universe's famous "Pink Planet." For more than a decade, the ancient, rosy-hazed world kept astronomers guessing. One of the coldest known ...
Medical Xpress / Gene therapy shows promise in ARC syndrome, a deadly childhood liver disease
A new gene therapy has been used to successfully treat a deadly childhood liver disease in mice that model the disease, according to researchers at UCL and Great Ormond Street Hospital. Arthrogryposis, renal dysfunction and ...
Phys.org / Bat rays employ a chemical cue to warn others of danger
Frightened bat rays produce a chemical cue to warn other rays of danger, a well-known anti-predator strategy for bony fish that has not been documented in cartilaginous fish until now. Oregon State University researchers ...
Phys.org / Energetic neutral atoms may help map Uranus's odd magnetic environment
Sending a spacecraft to the underexplored planet Uranus is at the top of many planetary scientists' wish lists. But which spacecraft-mounted instruments would be most useful for answering questions about the mysterious ice ...
Phys.org / Quasi-1D material unlocks electric control of charge waves beyond standard limits
The ability to control the movement of negatively charged particles (i.e., electrons) is central to the functioning of all modern electronic devices. This control is typically attained using a gate, an electrode via which ...
Medical Xpress / Vagus nerve stimulation may quiet pain through newly mapped brainstem pathway
Physical pain is essential for survival, as it allows animals to detect when they are injured or unwell, seek shelter and address their ailments. Yet when it becomes chronic, pain can also become highly distressing and debilitating.
