There’s no pain like nerve pain. Whether it is because of a chronic illness or related to an injury, it may be obvious, but nerve pain hurts. That may change soon though, as a specific molecule involved in maintaining pain after a nerve injury has been identified and blocked in mice by researchers. These results reveal a promising therapeutic strategy for treating neuropathic pain.
“I know kung fu,” movie buffs might remember the remember the quote from “The Matrix.” We can all probably agree that being able to download knowledge “on tap” would be a boon to humanity. It is a shame it is just a movie… right? While that may be the case, it is just for now. That is because researchers have discovered that low-current electrical brain stimulation can modulate the learning of complex real-world skills.
Life literally inside the world wide web, it’s an interesting idea. One that has tantalized sci-fi fans since before the framework for the internet was even finished. While the idea of a seemingly eternal disembodied life through the unfiltered and raw computer consciousness that we all share a connection with, maybe we are shooting for a goal that isn’t really possible — maybe we are asking the wrong questions.
Surprisingly complex interactions between neurotransmitter receptors and other key proteins help explain the brain’s ability to process information with lightning speed, according to a new study. Scientists at McGill University, working with collaborators at the universities of Oxford and Liverpool, combined experimental techniques to examine fast-acting protein macromolecules, known as AMPA receptors, which are a major player in brain signaling.
Scientists at the University of Michigan have found evidence that some carbon nanomaterials can enter into immune cell membranes, seemingly going undetected by the cell’s built-in mechanisms for engulfing and disposing of foreign material, and then escape through some unidentified pathway.
Immune cells that normally help us fight off bacterial and viral infections may play a far greater role in Alzheimer’s disease than originally thought, according to University of California, Irvine neurobiologists with the Sue & Bill Gross Stem Cell Research Center and the Institute for Memory Impairments and Neurological Disorders.
Antibiotic resistance is becoming a common occurrence. Once isolated, more and more we are turning away from the traditional antibiotics to our so called “last line of defense” antibiotics to fight infections. Sadly, in a growing number of cases these antibiotics are having less of an effect. However, new research reveals the mechanism by which drug-resistant bacterial cells maintain a defensive barrier.
What helps her live longer might be harmful to him, according to a new study that may shed light on how and why organisms age. Analyzing years of previous research on dietary and pharmaceutical tests on flies and mice, researchers showed that aging interventions can have opposite effects on mortality rates in males versus females.
Sexual assault, personally, I hate the phrase. It sounds much more tame than rape and I think we should call it like it is, rape. Sure that might make a person’s skin crawl just slightly — and that is frankly the point. Rape is ugly, it’s evil, it leaves an indelible mark on a person and unfortunately a new study shows that it may be worse. Researchers have discovered that prepubescent female rodents paired with sexually experienced males had elevated levels of stress hormones, could not learn as well, and expressed reduced maternal behaviors needed to care for offspring.
Viruses are molecular thieves that take from their hosts under the cloak of darkness. But now a Virginia Tech scientist has found a way to not only track viral hijackers, but also potentially stop them from replicating. The discovery has broad ranging applications in stopping viral outbreaks such as Hepatitis C in humans and a number of viruses in plants and animals because it applies to many viruses in the largest category of viral classes — positive-strand RNA viruses.
Have you ever had to deal with bouts of insomnia make you feel depressed? Well the good news is you’re not alone, in fact the two may be linked. A new study of firefighters suggests that insomnia and nightmares may increase the risk of depression by impairing the ability to access and leverage emotion regulation strategies effectively.
A critical but vulnerable region in the brain appears to be the first place affected by late onset Alzheimer’s disease and may be more important for maintaining cognitive function in later life than previously appreciated, according to a new review of the scientific literature.
Using a sophisticated, custom-designed 3D printer, regenerative medicine scientists at Wake Forest Baptist Medical Center have proved that it is feasible to print living tissue structures to replace injured or diseased tissue in patients. Scientists said they printed ear, bone and muscle structures. When implanted in animals, the structures matured into functional tissue and developed a system of blood vessels.
A new insight into how sharks regenerate their teeth, which may pave the way for the development of therapies to help humans with tooth loss, has been discovered by scientists. The study has identified a network of genes that enables sharks to develop and regenerate their teeth throughout their lifetime. The genes also allow sharks to replace rows of their teeth using a conveyer belt-like system.
Humans, like all social animals, have a fundamental need for contact with others. This deeply ingrained instinct helps us to survive; it’s much easier to find food, shelter, and other necessities with a group than alone. Deprived of human contact, most people become lonely and emotionally distressed.
Scientists at the UCLA Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research and Center for Duchenne Muscular Dystrophy at UCLA have developed a new approach that could eventually be used to treat Duchenne muscular dystrophy. The stem cell gene therapy could be applicable for 60 percent of people with Duchenne, which affects approximately 1 in 5,000 boys in the U.S. and is the most common fatal childhood genetic disease.
The age at which an adolescent begins using marijuana may affect typical brain development, according to researchers at the Center for BrainHealth at The University of Texas at Dallas. In a paper recently published, scientists describe how marijuana use, and the age at which use is initiated, may adversely alter brain structures that underlie higher order thinking.
Human and animal movements generate slight neural signals from their brain cells. These signals obtained using a neural interface are essential for realizing brain-machine interfaces (BMI). Such neural recording systems using wires to connect the implanted device to an external device can cause infections through the opening in the skull. One method of solving this issue is to develop a wireless neural interface that is fully implantable on the brain.
Researchers at the University of Minnesota have engineered a new synthetic biopathway that can more efficiently and cost-effectively turn agricultural waste, like corn stover and orange peels, into a variety of useful products ranging from spandex to chicken feed.
There may be a genetic connection between some mental health disorders and type 2 diabetes. In a new report, scientists show that a gene called “DISC1,” which is believed to play a role in mental health disorders, such as schizophrenia, bipolar disorder and some forms of depression, influences the function of pancreatic beta cells which produce insulin to maintain normal blood glucose levels.
Plasticity of the brain, what does that even mean? Well the good news is that it isn’t just a marketing ploy, the brain needs to be “plastic” because we need to be able to adapt. Frankly speaking, the brain still has a lot to learn about itself. Scientists at the Virginia Tech Carilion Research Institute have made a key finding of the striking differences in how the brain’s cells can change through experience.
Underwater sound linked to human activity could alter the behaviour of seabed creatures that play a vital role in marine ecosystems, according to new research from the University of Southampton. The study found that exposure to sounds that resemble shipping traffic and offshore construction activities results in behavioural responses in certain invertebrate species that live in the marine sediment.
More than two million citizens have been Tased by police as Taser stun guns have become one of the preferred less-lethal weapons by police departments across the United States during the past decade. But what does that 50,000-volt shock do to a person’s brain?
Depression is a serious issue for expecting mothers. Left untreated, depression could have implications for a fetus’s health. But treating the disease during pregnancy may carry health risks for the developing fetus, which makes an expecting mother’s decision whether to take medication a very difficult one. To better understand how antidepressants affect fetuses during pregnancy, scientists studied exposure in mice.
Inflammation is a good thing, it helps the body fight disease, and without it we wouldn’t survive. Unfortunately, when inflammation isn’t kept under control it can wreak havoc on the body. From potentially causing alzheimer’s to arthritis it seems that unchecked inflammation can cause all sorts of issues. In fact, a new study adds to the list of issues out of control inflammation causes in the body.
An estimated 1 in 68 children in the United States has autism. The neurodevelopmental disorder, which impairs communication and social interaction skills, can be treated with medications and behavioral therapies, though there is no cure. Now, University of Missouri researchers have found that a medication commonly used to treat high blood pressure and irregular heartbeats may have the potential to improve some social functions of individuals with autism.
