What are the limits of quantum physics? This is a question that has been researched around the world for decades. If we want to make the properties of the quantum world technically usable, we need to understand whether objects that are significantly larger than atoms and molecules can also exhibit quantum phenomena. For example, small glass spheres with a diameter of one hundred nanometres can be examined – still over a thousand times smaller than a grain of sand, but huge by quantum standards. For years, attempts have been made to show the extent to which such spheres ...

Japanese rice fish, known as medaka, are small, easy to breed, and reproduce daily, making them widely used as model organisms around the world. Until now, medaka research has mainly occurred in labs where environmental conditions and study observations are easily controlled. Unnatural environmental settings such as these bring into question the accuracy of previous behavioral findings. Therefore, this study is important for answering the fundamental question of whether the behavior of animals observed in laboratories is the same as in their natural environments. A ...

Chemistry and physics are combining forces at Columbia, and it’s leaving everyone frustrated—in a good way. New work, published today in Nature Physics, describes a new two-dimensional material capable of complex quantum behaviors that arise from its underlying chemistry, rather than its atomic structure.  “It’s a classic Columbia story—multiple groups in physics and chemistry came together to work on this new material, and we found exciting new results about how electrons move,” said Aravind Devarakonda, an applied physicist at Columbia Engineering.  The material, Pd5AlI2, ...

426,016. That’s how many packages of illegal medicines EU agencies confiscated during an eight-month operation in 2024. During the operation, they managed to find counterfeit medicines worth 11.1 million euros. And it’s an increasingly bigger problem. “Pharmaceutical crime is a growing threat in the EU,” Europol stated earlier this year. Fortunately, a new weapon against pharmaceutical counterfeiting may be on the way. Researchers from the University of Copenhagen and Stanford University have shown in a new study that it is possible to distinguish seemingly identical medicines at the molecular level – both across ...

Many animals, including humans, can flexibly modulate their responsiveness to sounds according to different situations. This ability allows them to optimize the use of their limited brain resources by prioritizing the processing of critical information at any given moment. In line with this idea, a research team at Nagoya University in Japan has demonstrated that when female fruit flies are eager to mate, dopaminergic signals can influence their sensitivity to sounds, including courtship sounds from males, which are an essential source of information for species reproduction. "We believe that this finding is the first step toward understanding the neural mechanisms that underlie ...

Large ocean animals can be protected throughout much of their lifecycle by huge Marine Protected Areas (MPAs), new research shows. Scientists tracked sea turtles, manta rays and seabirds – all of which travel far and wide to forage, breed and migrate – in the Chagos Archipelago MPA in the Indian Ocean. In total, 95% of tracking locations were recorded inside the MPA’s 640,000 square kilometre area – suggesting it is large enough to protect these wandering animals. The study – by a team including Exeter and Heriot-Watt universities and ZSL – also assessed the impact of a smaller 100,000 square kilometre MPA and found seabirds would be less well protected ...

Up to 60% of women experience some fear about giving birth, especially for the first time, but a new study shows why some women are more likely to stay calm and confident in the lead-up to childbirth. In a global first, researchers from Robert Gordon University in Scotland and the University of South Australia (UniSA) investigated the factors that help ease childbirth fears, rather than stoke them. They surveyed 88 pregnant women in their third trimester before attending antenatal classes in north-east ...

Niigata, Japan – A group led by the Department of Cell Biology at the Kidney Research Center, Niigata University revealed that elevated activity of cdc42 is a critical initiation event leading to proteinuria, and proposed that suppression of cdc42 activity could be a promising therapy for nephrotic syndrome. Glomerulus is a filtration unit of the kidney, and the glomerular capillary wall functions as a barrier, preventing the leak of plasma protein into urine. Proteinuria is a clinical symptom showing dysfunction of the barrier of glomerular capillary wall, and is an aggravating factor leading to kidney failure. Besides, ...

Sophia Antipolis, France: Analysis of over 36,000 people with high blood pressure has shown that taking more steps, even below the recommended daily target of 10,000 steps, and walking faster, is associated with a significant reduction in the risk of major problems of the heart and blood vessels.  The study, published today (Thursday) in the European Journal of Preventive Cardiology, found that compared to a daily step count of 2,300 steps, every extra 1,000 steps was linked to a 17% reduction in the risk of developing a major adverse cardiovascular event (MACE), up to 10,000 steps. Additional ...
