Previous studies assumed the grasping point was known and the target deformation could be achieved. The constraints were assumed to be constant during the ...

A team of Mount Sinai surgeons has performed the first heart-liver-kidney triple organ transplants in New York. They successfully completed two of these complex surgeries on patients from Westchester County, who have since returned home and are making full recoveries. Heart-liver-kidney transplants are extremely rare—only 58 have been done across the country since the United Network for Organ Sharing, the government agency that oversees transplantation, started tracking cases in 1987. The two procedures at The Mount Sinai Hospital, which took place on January 10 and March 8, were among only four to date in the ...

Sharks have been evolving for more than 450 million years, developing skeletons not from bone, but from a tough, mineralized form of cartilage. These creatures are more than just fast swimmers – they’re built for efficiency. Their spines act like natural springs, storing and releasing energy with each tailbeat, allowing them to move through the water with smooth, powerful grace. Now, scientists are peering inside shark skeletons at the nanoscale, revealing a microscopic “sharkitecture” that helps these ancient apex predators withstand extreme physical demands of constant motion. Using synchrotron X-ray nanotomography with detailed ...

Americans perceive small juries of content experts as the most legitimate moderators of potentially misleading content on social media, according to a survey, but perceive large, nationally representative or politically balanced juries with minimum knowledge qualifications as comparably legitimate. Social media content moderation policies tend to attract criticism, with some calling for more aggressive removal of harmful and misleading content and others decrying moderation as censorship and accusing expert moderators of being politically biased. Less clear is what the general public would like to see in terms of content ...

Efforts to limit the global temperature increase to 1.5°C under the Paris Climate Agreement may not go far enough to save the world’s ice sheets, according to a new study. Research led by Durham University, UK, suggests the target should instead be closer to 1°C to avoid significant losses from the polar ice sheets and prevent a further acceleration in sea level rise. The team reviewed a wealth of evidence to examine the effect that the 1.5°C target would have on the ice sheets in Greenland and Antarctica, which together store enough ice to raise global sea levels by almost 65 metres. The mass of ice lost from these ice ...

CAMBRIDGE, MA -- By combining information from many large datasets, MIT researchers have identified several new potential targets for treating or preventing Alzheimer’s disease. The study revealed genes and cellular pathways that haven’t been linked to Alzheimer’s before, including one involved in DNA repair. Identifying new drug targets is critical because many of the Alzheimer’s drugs that have been developed to this point haven’t been as successful as hoped. Working with researchers at Harvard Medical School, the team used data from humans and fruit flies to identify cellular pathways linked to neurodegeneration. ...

A combination of two drugs could improve outcomes and reduce the need for toxic chemotherapy for B-cell acute lymphoblastic leukaemia (B-ALL), the commonest cancer in childhood and one that can be particularly difficult to treat in older patients, according to Cambridge scientists. Although the research has so far only been conducted in cell lines and mice, the team is seeking funding to begin clinical trials in patients shortly. More than 500 people a year in the UK are diagnosed with B-ALL, many of whom are children, where it makes up 40% of all ...

CAMBRIDGE, MA -- Measuring the density of a cell can reveal a great deal about the cell’s state. As cells proliferate, differentiate, or undergo cell death, they may gain or lose water and other molecules, which is revealed by changes in density. Tracking these tiny changes in cells’ physical state is difficult to do at a large scale, especially with single-cell resolution, but a team of MIT researchers has now found a way to measure cell density quickly and accurately — measuring up to 30,000 cells in a single hour. The researchers also showed that density ...

Tokyo, Japan—The COVID-19 pandemic increased public awareness of the importance of mask use for personal protection. However, when the mesh size of mask fabrics is small enough to capture viruses, which are usually around one hundred nanometers in size, the fabric typically also restricts air flow, resulting in user discomfort. But now, researchers from Japan have found a way to avoid this. In a study published this month in Materials Advances, researchers from the Institute of Industrial Science, The University of Tokyo have overcome this bottleneck and developed a filter capable of capturing nanoparticles such ...
