Women actively infected with genital herpes during early pregnancy had twice the odds of giving birth to a child later diagnosed with autism spectrum disorder (ASD), according to a study.
Plumbing a 90 million-year-old layer cake of sedimentary rock in Colorado, a team of scientists has found evidence confirming a critical theory of how the planets in our solar system behave in their orbits around the sun. The finding is important because it provides the first hard proof for what scientists call the ''chaotic solar system.'
Scientists have found that as mice learn to associate a particular sound with a rewarding sugary drink, one set of prefrontal neurons becomes more active and promotes reward-seeking behavior while other prefrontal neurons are silenced, and those neurons act like a brake on reward-seeking.
Scientists at the Earth-Life Science Institute at the Tokyo Institute of Technology report in Nature (Fen. 22, 2017) unexpected discoveries about the Earth's core. The findings include insights into the source of energy driving the Earth's magnetic field, factors governing the cooling of the core and its chemical composition, and conditions that existed during the formation of the Earth.
A simple rule can accurately predict when Earth's climate warms out of an ice age, according to new research.
Scientists propose that blocking a molecule that drives inflammation and organ damage in Gaucher, and maybe other lysosomal storage diseases, as a possible treatment with fewer risks and lower costs than current therapies. The team conducted the study in mouse models of lysosomal storage disease and in cells from blood samples donated by people with Gaucher disease.
Researchers have harnessed the power of CRISPR/Cas9 to create more-potent chimeric antigen receptor (CAR) T cells that enhance tumor rejection in mice.
A prosthetic limb controlled by brain activity can partially recover the lost motor function. Neuroscientists asked whether it was possible to transmit the missing sensation back to the brain by stimulating neural activity in the cortex. They discovered that not only was it possible to create an artificial sensation of neuroprosthetic movements, but that the underlying learning process occurs very rapidly. These finding were obtained by resorting to imaging and optical stimulation tools.
New ways to convert carbon dioxide (CO2) into methane gas for energy use are a step closer after scientists discovered how bacteria make a component that facilitates the process. Recycling CO2 into energy has immense potential for making these emissions useful rather than a major factor in global warming. However, because the bacteria that can convert CO2 into methane, methanogens, are notoriously difficult to grow, their use in gas production remains limited.
NASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.
A new report released today presents the first global map of transshipment, a major pathway for illegally caught and unreported fish to enter the seafood market. Also associated with drug smuggling and slave labor, it is Illegal in many cases, and has been largely invisible until now. Using an artificial intelligence system developed by Global Fishing Watch, data scientists have developed an automated process for identifying and tracking transshipment around the world.
There are neurons in your skin that are wired to sense itchy things. These neurons are separate from the ones that detect pain, and yet, chemical-induced itch is often accompanied by mild pain such as burning and stinging sensations. But when it comes to sending signals toward your brain through your spinal cord, itch and mild pain can go through the same set of spinal cord neurons.
It may seem obvious, but the key to confirming whether someone is suffering from a cold or flu virus might lie at the misery's source -- the inflamed passages of the nose and throat. Scientists have identified a group of proteins that, when detected in specific quantities in the mucous, are 86 percent accurate in confirming the infection is from a cold or flu virus, according to a small, proof-of-concept trial.
Concussion testing on the athletic field depends upon comparing an athlete's post-concussion neurocognitive performance with the results of a previously administered baseline test. Experts believe some athletes, in hopes of a quicker post-injury return to play, may 'sandbag' the concussion test by giving a lackadaisical baseline performance. A researcher has developed a statistical technique to detect when an athlete is sandbagging.
Researchers report they can alter blood cell development through the use of biomaterials designed to mimic characteristics of the bone marrow.
Researchers have demonstrated how harmful health complications passed from mother rats to their offspring can be reversed. The tests may point the way toward preventing the transfer of certain health conditions from human mothers to their children.
Researchers provide insight into a phenomenon called ageing that leads to more powerful earthquakes.
We use others' eyes -- whether they're widened or narrowed -- to infer emotional states, and the inferences we make align with the optical function of those expressions, according to new research. The research reveals, for example, that people consistently associate narrowed eyes -- which can enhance visual discrimination -- with discrimination-related emotions including disgust and suspicion.
There's an idea out there of what a drug-addled teen is supposed to look like: impulsive, unconscientious, smart, perhaps -- but not the most engaged. While personality traits like that could signal danger, not every adolescent who fits that description becomes a problem drug user. So how do you tell who's who?
Two drugs used to treat asthma and allergies may offer a way to prevent a form of pneumonia that can kill up to 40 percent of people who contract it, researchers at the University of Virginia School of Medicine have found.
