Lizards can regrow severed tails, making them the closest relative to humans that can regenerate a lost appendage. But in lieu of the original tail that includes a spinal column and nerves, the replacement structure is an imperfect cartilage tube. Now, for the first time, a USC-led study in Nature Communications describes how stem cells can help lizards […]

Regular doses of the hormone oxytocin do not appear to overcome deficits in social functioning among children with autism spectrum disorder (ASD), suggests a study funded by the National Institutes of Health. The findings contradict earlier reports that indicated the hormone could alleviate the difficulties in social functioning characteristic of ASD. Oxytocin is associated with […]

For women who have undergone a mastectomy after breast cancer, the start-up firm Healshape has developed a 3D bioprinted breast implant that can be adapted to all body shapes. The aim is to reconstruct the entire breast using cells from the patient. Breast cancer is the most common cancer among women in France. More than […]

Particles called neutrons are typically very content inside atoms. They stick around for billions of years and longer inside some of the atoms that make up matter in our universe. But when neutrons are free and floating alone outside of an atom, they start to decay into protons and other particles. Their lifetime is short, […]

Most know the white cane as a simple-but-crucial tool that assists people with visual impairments in making their way through the world. Researchers at Stanford University have now introduced an affordable robotic cane that guides people with visual impairments safely and efficiently through their environments. Using tools from autonomous vehicles, the research team has built […]

By studying 110 children aged two weeks to 21 years who tested positive for COVID-19 at Massachusetts General Hospital (MGH) or urgent care clinics, researchers confirmed earlier findings that infants, children and adolescents are equally capable of carrying high levels of live, replicating SARS-CoV-2 in their respiratory secretions. The researchers at Harvard-affiliated MGH and colleagues […]

Israeli start-up Seebo’s machine learning technology combines artificial intelligence (AI) with insight into manufacturing processes to enable manufacturers, including those in the chemicals sector, to predict and prevent future production losses. Co-founded by brothers Liran and Lior Akavia in 2014, Seebo’s tools can reveal hidden inefficiencies in production processes – Seebo is an amalgamation of […]

Future sound of a Beatles playlist: drip, drip, drip In the digital age, every byte of data needs to go somewhere — and preferably stay there a long time. That last part is a major problem when it comes to data-storage systems, which typically last less than 20 years. A group of Harvard chemists is […]

As coronavirus cases continue to surge around the nation, President Biden has taken a harder stance against those unwilling to vaccinate by issuing vaccine mandates. Recent polling shows that most Americans continue to support his mandates so far—and 65% support a universal mandate. The survey from a consortium of universities, including Northwestern, Northeastern, Harvard and Rutgers, shows a majority […]

On the heels of announcing this year’s chemistry Nobel prize, the secretary general of the Royal Swedish Academy of Sciences, Göran Hansson, has announced that there will be no quotas for women or minorities when choosing laureates. ‘It is sad that there are so few women Nobel laureates and it reflects on the unfair conditions […]
