Medical Xpress / 'Off the shelf' immunotherapy could get a lift from gene-edited natural killer cells
Since scientists first discovered that human immune cells could be modified to become cancer-fighting agents, they've been trying to engineer a cell that's effective against solid tumors, which account for the vast majority ...
Medical Xpress / Yawns in healthy fetuses might indicate mild distress
Even in the womb, where all oxygen is provided by the parental placenta, fetuses can—and do—yawn. More yawns during observation were associated with a lower weight at birth—potentially indicating mild fetal stress in ...
Phys.org / Sunray-like ripples emerge on a frozen reaction front
Researchers in Belgium have unveiled a striking chemical reaction in which ripples along a frozen reaction front resemble the rays of a shining star. Publishing their results in Physical Review Letters, Anne De Wit and colleagues ...
Medical Xpress / New study maps what we do and don't know about outcomes for children in care
A new study led by Swansea University has mapped international evidence on the outcomes of children who grow up in out-of-home care. Drawing on 77 reviews, published between January 2013 and July 2024, research, shows which ...
Phys.org / Physicists watch light drift in quantized steps for the first time
In physics, the classical "Hall effect," discovered in the late 19th century, describes how a transverse voltage is generated when an electric current is exposed to a perpendicular magnetic field. Simply put, the magnetic ...
Medical Xpress / Gallbladder cancer could soon be detected in blood
Researchers at Tezpur University in Assam, India, working with scientists at the University of Illinois Urbana-Champaign, have identified distinct chemical signatures in blood that could help detect gallbladder cancer earlier. ...
Phys.org / Challenging assumptions behind Africa's Green Revolution efforts and calls for farmer-centered development models
A new study examining small-scale farming in Tanzania argues that major agricultural development initiatives, including the Alliance for a Green Revolution in Africa (AGRA), are built on flawed assumptions about how rural ...
Medical Xpress / AI, monkey brains, and the virtue of small thinking illuminate how the brain processes sight
What does it take to make AI that can pass as human? Try massive clusters of supercomputers. To build human-like intelligence, computer scientists think big. However, for neuroscientists who want to understand how real brains ...
Medical Xpress / In Rett syndrome, leaky brain blood vessels traced to microRNA
MIT researchers have discovered that two common genetic mutations that cause Rett syndrome each set off a molecular chain of events that compromises the structural integrity of developing brain blood vessels, making them ...
Phys.org / Canada's Magdalen Islands' peatlands hold vital clues about ancient Atlantic hurricanes
Eastern Canada has seen a rise in the number of hurricane- and near-hurricane strength events battering its maritime areas, with particularly violent storms in 2003 (Hurricane Juan), 2019 (Dorian) and 2022 (Fiona). While ...
Tech Xplore / Chatbots overemphasize sociodemographic stereotypes, researchers report
People interact with artificial intelligence (AI)-powered chatbots, which can be trained to take on certain demographic attributes like age and race, for information, entertainment, technical help, learning, emotional support, ...
Phys.org / Scientists develop vitamin A-enriched tomato to fight global deficiency
University of Florida scientists have developed a tomato packed with significantly higher levels of vitamin A, a breakthrough that could help combat one of the world's most widespread nutritional deficiencies. In research ...
