Medical Xpress / Broken bones regrow quickly with help of biodegradable scaffold that releases nutrients
For most broken bones, bone cells regrow on their own while patients wear a cast or brace to keep the injury steady. But for complex or severe fractures, surgeons may intervene by placing grafts or scaffolds made of biocompatible ...
Tech Xplore / AI method reconstructs 3D scene details from simulated images using inverse rendering
Over the past decades, computer scientists have developed many computational tools that can analyze and interpret images. These tools have proved useful for a broad range of applications, including robotics, autonomous driving, ...
Medical Xpress / AI chatbots found to be inconsistent in answering questions about suicide
Three widely used artificial intelligence chatbots generally do a good job responding to very-high-risk and very-low-risk questions about suicide, but they are inconsistent in answering questions about suicide that may pose ...
Medical Xpress / Hypoxia leads to reduced dental bone formation during orthodontic tooth movement in rats
Sustained hypoxia affects orthodontic tooth movement (OTM) by altering osteoclast and osteoblast differentiation, report researchers from the Institute of Science Tokyo, Japan. Hypoxic conditions resulted in reduced alveolar ...
Medical Xpress / Scientists discover new '3D genome organizer' linked to fertility and cancer
A research team at Kyoto University has discovered STAG3-cohesin, a new mitotic cohesin complex that helps establish the unique DNA architecture of spermatogonial stem cells (SSCs), the stem cells that give rise to sperm. ...
Phys.org / Idaho poisoned Snake River for invasive mussels: Was it worth 'heartbreaking' loss?
The invasive quagga mussels found in an Idaho river in 2023 were microscopic. But to state officials, their presence was enormous.
Phys.org / LHCb collaboration observes ultra-rare baryon decay
Baryons, composite particles made up of three quarks bound together via the so-called strong force, make up the most visible matter and have thus been the focus of numerous physics studies. Studying the rare processes via ...
Phys.org / Dark energy-filled black holes plus DESI data give neutrino masses that make sense
These are exciting times to explore the largest unanswered questions in physics thanks to high-tech experiments and very precise data. That's particularly true of dark energy, the name given to the mysterious driver of the ...
Medical Xpress / Two thirds of reproductive-aged women have at least one modifiable risk factor for birth defects, study reveals
An analysis using data from the National Health and Nutrition Examination Survey (NHANES) among 5,374 women of reproductive age indicates that two thirds of women within this demographic have at least one modifiable risk ...
Medical Xpress / Mediterranean diet combined with calorie reduction and exercise may reduce risk of type 2 diabetes
A Mediterranean-style diet, in combination with reduced caloric intake, moderate physical activity, and professional support for weight loss, may cut the risk of type 2 diabetes (T2D) by 31%, according to a new study co-authored ...
Phys.org / Caterpillars actively suppress pain by striking a sphinx pose
When tobacco hornworm caterpillars feel pain, they don't wriggle or try to escape. Instead, according to the latest research, they dial down their pain response by adopting a posture known as the "sphinx" state, so called ...
Tech Xplore / Virtual reality merges with robotics to create seamless physical interactions
Computer scientists at Princeton are working to bring virtual reality into the physical world, with the potential to enhance a variety of experiences, including remote collaboration, education, entertainment and gaming.
