Most #materials go from being solids to liquids when they are heated. One rare counter-example is helium-3, which can solidify upon heating. This counterintuitive and exotic effect, known as the Pomeranchuk effect, may now have found its electronic analog in a #material known as magic-angle graphene, says a team of researchers from the Weizmann Institute…
Understanding Itch: New Insights at the Intersection of the Nervous System & Immune System
Eczema, or atopic dermatitis (AD), is sometimes called “the itch that rashes.” Often, the itch begins before the rash appears, and, in many cases, the itchiness of the skin condition never really goes away. Approximately 9.6 million children and 16.5 million adults in the U.S. have AD, which can have a serious effect on quality…
Leaky Blood-Brain Barrier Linked to Brain Tissue Damage in Brain Aging Disease
As people age, changes in the tiniest blood vessels in the brain, a condition called cerebral small vessel disease, can lead to thinking and memory problems and stroke. These changes can also affect the blood-brain barrier, a layer of cells that protect the brain from toxins circulating in the blood. Now a new study has…
Promising Results for Focused Ultrasound Treatment of Alzheimer’s
West Virginia University scientists used MRI scans to show what happens when ultrasound waves target a specific area of Alzheimer’s patient’s brains. They concluded that this treatment may induce an immunological healing response, a potential breakthrough for a disease that accounts for up to 80% of all dementia cases. Rashi Mehta, a researcher with the…
High Insulin Levels During Childhood a Risk for Mental Health Problems in Adulthood
Researchers have shown that the link between physical and mental illness is closer than previously thought. Certain changes in physical health, which are detectable in childhood, are linked with the development of mental illness in adulthood. The researchers, led by the University of Cambridge, used a sample of over 10,000 people to study how insulin…
New Antidepressants Can Lift Depression and Suicidal Thoughts Fast, but Don’t Expect Magic Cures
Depression is the most common cause of disability in the world. Chances are high that you or someone you know will experience a period when depression gets in the way of work, social life or family life. Nearly two in three people with depression will experience severe effects. As a psychiatrist specializing in behavioral neuroscience, I help patients who suffer…
Exposure to Metals Can Impact Pregnancy
Exposure to metals such as nickel, arsenic, cobalt and lead may disrupt a woman’s hormones during pregnancy, according to a Rutgers study. The study appears in the journal Environment International. Exposure to metals has been associated with problems at birth such as preterm birth and low birth weight in babies, and preeclampsia in women. However, little…
Brains Work Harder While Processing Descriptions of Motion in Other Languages
We all run from a burning building the same way–fast!–but how we describe it depends on the language we speak. In some languages, we might flee, race, or bolt, while in others we might just exit or leave the building quickly.. Different languages describe motion differently, according to distinct lexical rules. And though we may…
Spotting Liars Is Hard, but Our New Method Is Effective and Ethical
Most people lie occasionally. The lies are often trivial and essentially inconsequential – such as pretending to like a tasteless gift. But in other contexts, deception is more serious and can have harmful effects on criminal justice. From a societal perspective, such lying is better detected than ignored and tolerated. Unfortunately, it is difficult to…
Mothers’ Stress May Lead to Preterm Births, Faster Aging in Children
Why do some people age faster than others? One potential answer, a new UCLA-led study indicates, is that a mother’s stress prior to giving birth may accelerate her child’s biological aging. The researchers found evidence that maternal stress adversely affects the length of a baby’s telomeres — the small pieces of DNA at the ends…
A Modified Game of ‘Chicken’ Reveals What Happens in the Brain During Decision-Making
Better understanding what happens in the brain when people cooperate and make social decisions has the potential to help boost such behaviors. It’s been a research focus for the University of Pennsylvania’s Platt Labs for some time. “The social brain network contains a number of different areas critical to managing interactions and connecting with others,” says Penn Integrates Knowledge Professor Michael…
Drug Reverses Age-Related Cognitive Decline Within Days
Just a few doses of an experimental drug can reverse age-related declines in memory and mental flexibility in mice, according to a new study by UC San Francisco scientists. The drug, called ISRIB, has already been shown in laboratory studies to restore memory function months after traumatic brain injury (TBI), reverse cognitive impairments in Down Syndrome, prevent noise-related hearing loss, fight certain types…
Children With Dyslexia Show Stronger Emotional Responses
Children diagnosed with dyslexia show greater emotional reactivity than children without dyslexia, according to a new collaborative study by UC San Francisco neuroscientists with the UCSF Dyslexia Center and UCSF Memory and Aging Center. In the study, published online in an early form November 20, 2020 in Cortex, children with dyslexia who watched emotionally evocative videos…
Amblyopia screening with the dynamic random-dot stereo test
A new amblyopia screening system that can be used on Android devices has performed better than some of the ‘gold standard’ stereotests in recent Hungarian studies. Submit your abstract at Pediatric #Ophthalmology 2021. Scientific Committee will be honoured to welcome you to the 6th Global Pediatric Ophthalmology Congress to be held during March 08-09, 2021 Webinar. https://lnkd.in/gdcAJKw Amblyopia…
Going beyond the Heart blockages: The Non Invasive treatments
This is a shocking statement considering an impressive array of treatments available to today’s heart specialists. With coronary artery bypass surgeries, angioplasty, stent implementation plus many other sophisticated high-end tests with the odds seeming to favour 21st-century patients. Not only are all these techniques aggressive and expensive, but the real problem here is also that…
Changes in your heart after 40 years of age
When it comes to health, especially after the age of 40, what you cannot notice at first glance can hurt you the most. In the heart, 40 is the key age when serious but invisible changes begin in the cardiovascular system. Read through what changes your body goes through The heart muscle becomes thicker Solid…
New drug limits damage to heart muscle from heart attack
An experimental drug has shown great promise in limiting the damage that a heart attack can inflict on the heart. It targets a protein that plays a central role in the death of heart muscle cells. Tests on mice have revealed that the drug could markedly reduce heart injury from a heart attack. The small-molecule drug…
The Heart of The Matter: Technology In The Future of Cardiology
Sound, rhythm, rate, structure, function – countless features of the heart are measured to keep it healthy for as long as possible. Recently, an army of digital health technologies joined the forces of traditional preventive tools in cardiology to counter stroke, heart attack, heart failure or any other cardiovascular risks. In the future, minuscule sensors, digital…
