Medical Xpress / How physical activity may help cancer survivors live longer
Staying fit and active has long been associated with better heart and overall health. It might also improve the chances of survival for people with some forms of cancer. A study published in the journal JAMA Network Open ...
Phys.org / The bouba-kiki effect: Baby chicks match sounds to shapes just like humans
When we hear certain sounds, our brains often pair them with specific shapes. For example, most people will associate a sharp-sounding word with a jagged, pointed shape, while a soft, rolling word is linked to something smooth ...
Medical Xpress / Why nighttime heat drives a surge in suicide-related calls to crisis lines in Louisiana
Extreme heat poses serious risks to physical health but can also trigger a mental health emergency for some people. While the link between heat and suicide is well-documented, the specific stressors that drive someone to ...
Phys.org / Pregnancy complications may have helped wipe out Neanderthals
Neanderthals disappeared from the fossil record approximately 40,000 years ago. Their extinction was a gradual process over thousands of years, and theories as to why include competition with modern humans and rapid climate ...
Medical Xpress / DeepRare AI outperforms doctors on rare disease diagnosis in head-to-head test
Rare diseases are complex medical disorders that are notoriously difficult to diagnose because many present with a wide variety of symptoms that can overlap with more common illnesses. Currently, around 300 million people ...
Phys.org / Hiding in plain sight: Discovery of cryptic species could double the number of vertebrates
There may be twice as many vertebrates on the planet as previous estimates claimed, according to a new study published in the journal Proceedings of the Royal Society B: Biological Sciences. That's not because of any errors ...
Phys.org / A super stable laser on the moon could guide future lunar missions and improve our timekeeping
Scientists are proposing to build a laser in a crater on the moon to help future lunar missions land safely in the dark and find their way around. This ultra-stable light source could also help us keep time more accurately, ...
Phys.org / How the humble silkworm could help us discover new anti-aging treatments
When scientists want to study aging and how to slow it down, they often turn to microscopic worms or lab mice among other models. The former are too different from humans, while the latter are expensive and take too long ...
Phys.org / The cooling system that lets bees beat the heat when hovering
To stay in the air when hovering over a flower, bumble bees continually flap their wings rapidly, a metabolic process that generates a massive amount of internal heat. Their flight muscles work so intensely that they can ...
Tech Xplore / Robot hand approaches human-like dexterity with new visual-tactile training
Human hands are a wonder of nature and unmatched in the animal kingdom. They can twist caps, flick switches, handle tiny objects with ease, and perform thousands of tasks every day. Robot hands struggle to keep up. They typically ...
Tech Xplore / Ultrafast 3D printing method creates complex objects in under a second
High-speed 3D printing has just gotten a lot faster. Researchers from Tsinghua University in China have developed a new high-speed printing technology capable of creating complex millimeter-scale objects in just 0.6 seconds. ...
Phys.org / Massive ceramics haul from a 14th-century shipwreck reveals Singapore's trading past
Singapore was a thriving trading hub hundreds of years before popular narratives depicted it as a quiet fishing village, according to a study of the cargo of a centuries-old shipwreck. Sometime during the middle of the 14th ...
Phys.org / How one genome creates two distinct fungal bodies
Creatures that can change from one form to another are a staple of science fiction: Think werewolves and Transformers. Nature, too, has its shapeshifters, such as dimorphic fungi. While scientists have known for some time ...
Medical Xpress / Being physically fit may keep you calm under pressure
Regular exercise is not only good for the body, but it may also help you stay cool under pressure. Research published in the journal Acta Psychologica found that higher cardiorespiratory fitness (CRF) is associated with lower ...
Medical Xpress / The five healthy diets that could add extra years to your life
The old saying "you are what you eat" suggests that our food choices determine our health and longevity. Now, a study published in the journal Science Advances has put some specifics on it by estimating how many extra years ...
