In a paper published in Science Advances, the researchers showed that bringing together two magnets so that they pinch and apply pressure to a fold of skin, led to short term changes in the skin barrier and specifically the formation of "micropores" underneath its surface. In tests, they showed that these mic.. hydrogel-solid bonding A University of Sydney team of biomedical engineers has developed a plasma technology to robustly attach hydrogels—a jelly-like substance which is structurally similar to soft tissue in the human body—to polymeric materials, allowing manufactured devices to better interact with surrounding tissue. successfully combined hydrogels including those made from silk with Teflon and polystyrene polymers.. 어른이 되었을 때의 사회생활과 어릴 때 스트레스의 관계 When baboons experience trauma in early life, they have higher levels of stress hormones in adulthood—a potential marker of poor health—than their peers who don't experience trauma, even if they have strong social relationships as adults, according to a study led by a University of Michigan researcher. The study examined the links between childhood adversity, adult social relationships and gluco.. 아이의 트라우마와 노화 Children who suffer trauma from abuse or violence early in life show biological signs of aging faster than children who have never experienced adversity. The study examined three different signs of biological aging—early puberty, cellular aging and changes in brain structure—and found that trauma exposure was associated with all three. those studies looked at many different types of adversity—ab.. 먹는 것과 머리카락의 관계 your hair is building a record of your diet. As hair strands are built from amino acids that come from your food, they preserve the chemical traces of the protein in that food. It's a strong enough record to show whether you prefer veggie burgers or double bacon cheeseburgers. Beginning in the 1990s, Ehleringer, distinguished professors Denise Dearing and Thure Cerling and colleagues started loo.. deep learning이 잘 돌아가는 이유 "Deep learning was in some ways an accidental discovery," "We still do not understand why it works. A theoretical framework is taking form, and I believe that we are now close to a satisfactory theory. It is time to stand back and review recent insights." Our current era is marked by a superabundance of data—data from inexpensive sensors of all types, text, the internet, and large amounts of gen.. drawn on skin sensor has developed a new form of electronics known as "drawn-on-skin electronics," allowing multifunctional sensors and circuits to be drawn on the skin with an ink pen. The advance, the researchers report in Nature Communications, allows for the collection of more precise, motion artifact-free health data, solving the long-standing problem of collecting precise biological data through a wearable dev.. neurotransmitter lipid를 이용하여 BBB 통과하기 Biomedical engineers at the Tufts University School of Engineering have developed tiny lipid-based nanoparticles that incorporate neurotranmitters to help carry drugs, large molecules, and even gene editing proteins across the blood-brain barrier and into the brain in mice. We can deliver a wide range of molecules by packaging them into the lipid-based nanonparticles without chemically modifying.. 이전 1 ··· 6 7 8 9 10 11 12 ··· 19 다음
