Phys.org / How birds send heat into space measured for the first time—a hidden reflectance of feathers
As human-caused climate change continues to raise temperatures across the globe, understanding how birds regulate their temperature is vital for their conservation. But how much heat birds emit—an invisible spectrum of ...
Phys.org / Quantum computers could have a fundamental limit after all
The performance of quantum computers could cap out after around 1,000 qubits, according to a new analysis published in the Proceedings of the National Academy of Sciences. Through new calculations, Tim Palmer at the University ...
Phys.org / How archaeology is preserving evidence of the Yahidne war crime
Archaeology is not just a powerful tool for revealing insights into the ancient past, but it can also be applied to more recent events. In a new paper published in the journal Antiquity, scientists reveal how archaeological ...
Phys.org / Europe's Late Neanderthals descended from a single population, DNA analysis suggests
A study incorporating new DNA data and archaeological evidence has shown that the last Neanderthals in Europe experienced a major population turnover, resulting in little diversity in their gene pool prior to their disappearance ...
Phys.org / AI approach uncovers dozens of hidden planets in NASA's TESS data
Astronomers at the University of Warwick have validated over 100 exoplanets, including 31 newly detected planets, using a new artificial intelligence tool applied to data from NASA's Transiting Exoplanet Survey Satellite ...
Medical Xpress / How groups of neurons support the formation of memories
Neuroscientists and psychologists have been trying to understand how the human brain supports learning and the encoding of memories for over a century. Past studies suggest that memories are stored by groups of brain cells ...
Tech Xplore / New bifacial solar cells yield efficiencies above 32%
Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries worldwide. Over the past few years, energy engineers have been exploring alternative designs that could further boost ...
Phys.org / The hidden cost of sperm storage: Ejaculates found to deteriorate across the animal kingdom
Current World Health Organization (WHO) guidelines typically recommend two to seven days of abstinence before taking semen samples or assisted reproduction. However, a new study led by Oxford University researchers suggests ...
Phys.org / Superconducting quantum processor performs well with significantly less wiring
Quantum computers, computing systems that process information using quantum mechanical effects, could outperform classical computers on some computational tasks. These computers rely on qubits, the basic units of quantum ...
Phys.org / Hawaii tests asphalt made with recycled plastics and fishing nets for shedding
Hawaii has a plastic problem. The island state faces economic and logistical challenges in recycling plastic waste, including marine debris that lingers in its ocean waters. Researchers in Hawaii are pioneering a method to ...
Phys.org / Dishwashing with side effects: Kitchen sponges release microplastics
Kitchen sponges are considered a potential, yet largely understudied, source of microplastics in households. A study in Environmental Advances investigated how many microplastic particles are released from kitchen sponges ...
Phys.org / Chatting with people beats interactions with AI chatbots when it comes to reducing loneliness
More and more people are turning to AI chatbots as if they were close friends—venting about personal struggles, asking for advice, and even sharing their deepest secrets. These conversations can feel strikingly real, with ...
