The findings, published today in the journal Science Advances, shed new light on genomic imprinting, a fundamental, biological process in which a gene…
A study of twins shows that having a concussion early in life is tied to having lower scores on tests of thinking and memory skills decades later as well as having more rapid decline in those scores than twins who did not have a concussion, or traumatic brain injury (TBI).…
The shape and size of a grain of rice, the new device can conduct dozens of experiments at once to study the effects of new treatments on some of the hardest-to-treat brain cancers. Researchers from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, have…
As the Earth’s human population grows, greenhouse gas emissions from the world’s food system are on track to expand. A new study demonstrates that state-of-the-art agricultural technology and management can not only reduce that growth, but eliminate it altogether by generating net negative emissions — reducing more greenhouse gas than…
Remembering the order of information is central for a person when participating in conversations, planning everyday life, or undergoing an education. A new study, published in the scientific journal PLoS One, shows that this ability is probably human unique. Even the closest relatives of humans, such as bonobos, do not…
Not only does a lack of sleep make you feel awful, research has shown it impairs the brain. What’s more, sleep loss over long periods can even increase risk for Alzheimer’s and other neurological diseases. Researchers want to understand how sleep deprivation causes this harm. In a new study in…
A good night’s sleep has many proven health benefits, and a new Scripps Research study suggests one more: preventing opioid relapse. In the new study, published online in Neuropharmacologyon August 12, 2023, scientists gave an experimental insomnia treatment to rats experiencing oxycodone withdrawal. The researchers found that the animals were…
The researchers studied birds given a simulated bacterial infection in order to stimulate their immune system. The birds were then compared with birds whose immune system was not stimulated — and their activity was measured for several weeks using miniature data loggers. “We found that the birds whose immune system…
The treadmill exercise test with electrocardiogram (ECG), also known as an exercise stress test, is one of the most familiar tests in medicine. While exercise testing typically is focused on diagnosing coronary artery disease, a recent study from Mayo Clinic finds that exercise test abnormalities, such as low functional aerobic…
CNN — A serving member of the British Army awaiting trial on terror charges escaped from prison in London on Wednesday, the city’s Metropolitan Police said. Daniel Abed Khalife went missing from Wandsworth prison, in the southwest of the British capital, shortly before 8 a.m. UK time. He had been…
CNN — At least 16 people have been killed, including a child, after a Russian missile struck a market in a town in the eastern Ukrainian region of Donetsk, officials said, one of the worst attacks in months. Ukrainian officials said 28 others were wounded in the attack on Kostiantynivka.…

It came as a surprise to Professor David Lo and his graduate student Diana Del Castillo when they were recently consulted by researchers in Israel for their expertise on specialized cells called Microfold cells, or M cells, which are mostly known for their presence in the intestinal epithelium. The Israeli…
MIT researchers have demonstrated the first system for ultra-low-power underwater networking and communication, which can transmit signals across kilometer-scale distances. This technique, which the researchers began developing several years ago, uses about one-millionth the power that existing underwater communication methods use. By expanding their battery-free system’s communication range, the researchers…
A groundbreaking study led by experts from Indiana University School of Medicine has shed new light on the genetic underpinnings of Alzheimer’s disease. The team’s research, rooted in human genetics studies, has unearthed a critical mutation within a key gene operating in the brain’s immune cells, potentially elevating the risk…
New “hypervirulent” strains of the bacterium Klebsiella pneumoniae have emerged in healthy people in community settings, prompting a National Institutes of Health research group to investigate how the human immune system defends against infection. After exposing the strains to components of the human immune system in a laboratory “test tube”…
CNN — At least seven people have died and several remain missing across Greece, Turkey and Bulgaria as torrential rain and severe flooding batter southern Europe. Flooding has claimed at least two lives in mainland Greece, two in northwestern Turkey and left at least three people dead on Bulgaria’s Black…
Scripps Research chemists have extended a powerful molecule-building method — called C-H activation — to the broad class of chemicals known as alcohols.
