Medical Xpress / A good night's sleep begins with healthy gut bacteria. Here's how to look after yours
It's no accident that we spend a third of our lives asleep. It is essential to our health, and even animals for whom resting is complicated—such as aquatic mammals that need to surface to breathe, or birds that go up to 10 ...
Tech Xplore / New technology makes it possible to be a seafarer—on land
Uncrewed vessels can navigate themselves and notify operators when they need support from shore-based navigators. However, such ships also require an international regulatory framework. Now, the first version is in place, ...
Phys.org / Mysterious signals keep coming from space: Astronomers find their 'Rosetta stone'
A pair of stars spiraling around each other. That's the origin of a new source of repeating radio bursts we've detected, called ASKAP J1745.
Phys.org / Wonderwerk Cave bones reveal possible fire use by human ancestors 1.79 million years ago
The discovery of fire was a major milestone in human evolution, giving our ancestors a way to stay warm, ward off predators, and eventually start cooking food. But exactly when this first happened is still intensely debated, ...
Medical Xpress / AI-designed universal vaccine clears first human trial, targets future coronavirus threats with needle-free delivery
The first human clinical trial of a universal Sarbeco coronavirus vaccine, developed by the University of Cambridge and spin-out DIOSynVax (DVX) Ltd, has shown that the vaccine is safe and has no significant side effects.
Phys.org / Atlantic 'cold blob' caused by weakening ocean current system that's likely nearing a tipping point, reanalysis finds
A part of the Atlantic Ocean, just south of Greenland and Iceland, has been cooling off while the rest of the world gets hotter. This enigmatic patch is often referred to as the "cold blob" and scientists have been trying ...
Medical Xpress / Simple leukemia treatment change in India cuts early child deaths
A landmark Indian clinical trial has found that giving steroids in short bursts instead of continuously can halve early treatment-related deaths in children with leukemia without reducing their chances of being cured. The ...
Phys.org / Lunar orbiter concept could reveal five key elements across moon in two years
Researchers from Tokyo Metropolitan University have used simulations to show that a newly developed, compact X-ray telescope could be used to map the chemical composition of the entire lunar surface, a vital breakthrough ...
Phys.org / How gene swapping helped build the planet's decomposers
Decomposers are crucial for keeping Earth habitable, breaking down dead biomass and returning key nutrients, such as carbon, nitrogen and phosphorus, to the ecosystem. Most decomposers, including fungi, survive through osmotrophy—a ...
Tech Xplore / Jumping spiders inspire ultra-efficient 3D camera
By borrowing a trick from tiny jumping spiders, Northwestern University engineers have developed an extremely energy-efficient 3D camera. Called SpiderCam, the new device senses depth the same way that jumping spiders judge ...
Medical Xpress / Weight loss treatments linked to lower risk of obesity-related cancers in people without diabetes
A study of more than 229,000 obese adults without diabetes in the United States has shown that weight loss drugs are associated with a decreased risk of obesity-related cancers. The research found that GLP-1 receptor agonists ...
Phys.org / Continuous stirring made early life-like RNA systems more extinction-prone, experiment shows
Recent research showed that an artificially constructed self-replicating RNA system modeling primitive life at the origin of life evolved to become more prone to extinction under certain experimental conditions.
