Researchers explored innovative therapeutic strategies that could greatly advance the understanding and management of OSA-related morbidities. A groundbreaking study provides new insights into the treatment of obstructive sleep apnea (OSA) and its associated health impacts.
A new study provides further evidence that the Nord Stream seismic signals came from a complex source. The signals lasted longer than would be expected from a single explosive source, the researchers say, and were more like the signals detected from an underwater volcano or a pipeline venting gas.
For children, the world is full of surprises. Adults, on the other hand, are much more difficult to surprise. And there are complex processes behind this apparently straightforward state of affairs. Researchers have been using mice to decode how reactions to the unexpected develop in the growing brain.
Because same-sex sexual behavior does not result in offspring, evolutionary biologists have long wondered how the genes associated with this behavior have persisted in the human genome, and whether they will remain in the future. A new study suggests that part of the explanation -- specifically for male bisexuals -- has to do with risk-taking behavior.
We all know someone who's had a head injury that was 'only' a concussion, but even mild traumatic brain injuries can cause lasting damage, and the vast majority are never diagnosed. A team created a way to diagnose mild TBIs (mTBIs) even when MRI scans showed nothing, using the body's own immune cells called macrophages. They attached microparticle 'backpacks' containing a common MRI contrast agent to the cells, which migrated to the brain and allowed them to see evidence of inflammation in pigs with a mock mTBI.
Fossils of a new group of animal predators have been located in the Early Cambrian Sirius Passet fossil locality in North Greenland. These large worms may be some of the earliest carnivorous animals to have colonized the water column more than 518 million years ago, revealing a past dynasty of predators that scientists didn't know existed.
Traumatic brain injuries (TBIs) can cause lasting damage, but stopping the rampant brain inflammation they cause is difficult. A team at the Wyss, @SEAS and @MGH led by Samir Mitragotri has made a new treatment using macrophages -- immune cells that migrate to the brain. By attaching microparticle 'backpacks' that kept the macrophages in a healing state, they reduced the size of brain lesions by 56% in pigs with a mock TBI.
Researchers have determined how Eastern equine encephalitis virus attaches to a receptor it uses to enter and infect cells. The findings laid the groundwork for a receptor decoy molecule that protects mice from encephalitis caused by the virus.
Researchers have created the first functional semiconductor made from graphene, a single sheet of carbon atoms held together by the strongest bonds known. The breakthrough throws open the door to a new way of doing electronics.
Chlorophyll plays a pivotal role in photosynthesis, which is why plants have evolved to have high chlorophyll levels in their leaves. However, making this pigment is expensive because plants invest a significant portion of the available nitrogen in both chlorophyll and the special proteins that bind it. As a result, nitrogen is unavailable for other processes. In a new study, researchers reduced the chlorophyll levels in leaves to see if the plant would invest the nitrogen saved into other process that might improve nutritional quality.
New research reveals how corrosion happens on the atomic level.
A new study finds that older adult drivers who are recently diagnosed with migraines are three times as likely to experience a motor vehicle crash. Older adult drivers who reported having ever had migraines in the past were no more likely to have a motor vehicle crash than those without migraines.
Using state-of-the-art cell imaging and genome editing technology, scientists have begun to unravel how this collection of proteins performs its essential service. The discovery could eventually help researchers better understand and develop new treatments for diseases like cancer, diabetes and those that cause immune dysfunction.
With recent requirements for reducing greenhouse gas emissions of autonomous ships, an emerging body of research is focused on assessing the path-following performance of maritime autonomous surface ships (MASS) at low speeds under adverse weather conditions. To combat the poor accuracy of traditional methods, in a new study, researchers investigated the path-following performance of MASS using a free-running computational fluid dynamics model. Their findings can help ensure safer autonomous navigation with reduced propulsion power.
Sentences with greater linguistic complexity are most likely to fire up a key brain language processing center, according to a study that employed an artificial language network.
Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to fungal-based food webs for several high-latitude species, with potential indirect effects on nutrient cycling and ecosystem function.
Many bacterial pathogens use small injection apparatuses to manipulate the cells of their hosts, such as humans, so that they can spread throughout the body. To do this, they need to fill their syringes with the relevant injection agent. A technique that tracks the individual movement of proteins revealed how bacteria accomplish this challenging task.
Mutations of the tumor suppressor p53 not only have a growth-promoting effect on the cancer cells themselves, but also influence the cells in the tumor's microenvironment. Scientists have now shown that p53-mutated mouse breast cancer cells reprogram fat cells. The manipulated fat cells create an inflammatory microenvironment, impairing the immune response against the tumor and thus promoting cancer growth.
Primate social organization is more flexible than previously assumed. According to a new study, the first primates probably lived in pairs, while only around 15 percent of individuals were solitary.
