A new study by researchers at Karolinska Institutet shows that the protein alpha-synuclein, which accumulates in patients with Parkinson’s disease, occurs bound to lipoprotein particles in cerebrospinal fluid, which may explain how the disease spreads in the nervous system. The study is published in the scientific journal PNAS. Some 23,000 […]

Researchers at the Stanford University School of Medicine have found that neural signatures in sleeping zebrafish are analogous to those of humans, suggesting that the brain activity evolved at least 450 million years ago, before any creatures crawled out of the ocean. Scientists have known for more than 100 years that fish […]

An injection of nanoparticles can prevent the body’s immune system from overreacting to trauma, potentially preventing some spinal cord injuries from resulting in paralysis. The approach was demonstrated in mice at the University of Michigan, with the nanoparticles enhancing healing by reprogramming the aggressive immune cells—call it an “EpiPen” for […]

Their research has been published in the international journal Frontiers in Immunology. Oesophageal cancer is a very aggressive type […]

When it comes to killing cancer cells, two drugs are often better than one. Some drug combinations offer a one-two punch that kills cells more effectively, requires lower doses of each drug, and can help to prevent drug resistance. MIT biologists have now found that by combining two existing classes […]

New research from the University at Buffalo provides pathophysiologic evidence of the effect of air pollution on cardiovascular disease in China. The findings also suggests that China may need to revise its standard for one type of pollutant. Researchers found that long-term exposure to particulate matter and nitrogen dioxide, as […]

A new study from the University of Pittsburgh Graduate School of Public Health and UPMC Hillman Cancer Center found that children born to obese mothers were more likely to develop cancer in early childhood. Using Pennsylvania birth records, the researchers found a correlation between pre-pregnancy body-mass index (BMI) in mothers and subsequent cancer diagnosis […]

Certain plants, insects, crustaceans and fish possess the uncanny ability to change the sex of their offspring before they are born. Mammals have never before demonstrated this genetic skill, until now. A new Tel Aviv University study reveals a genetic system in mammals that enables two animals to mate and produce only […]

Their findings, published in Nature Ecology and Evolution, come from a detailed assessment of 121 species ranging from humans to sponges, may have important implications for conservation strategies and for predicting which species will be the winners and losers from the global environment crisis. “Pace of life” relates to how […]

A new machine-learning method accurately identifies regions of the human genome that have been duplicated or deleted — known as copy number variants — that are often associated with autism and other neurodevelopmental disorders. The new method, developed by researchers at Penn State, integrates data from several algorithms that attempt […]

A worldwide coalition of researchers and clinicians has agreed that light therapy is among the most effective interventions for the prevention of oral mucositis, painful ulcers in the mouth resulting from cancer therapy. The new guidelines from the Multinational Association of Supportive Care in Cancer (MASCC) and International Society of […]

The finding is a promising step forward in understanding eye growth – and potentially fixing near- and far-sightedness. Those with a rare genetic condition called nanophthalmos have abnormally small eyes whose internal structures – including the size of the lens – are otherwise normal. The condition can cause a host […]

In recent decades, treatment options for people with cystic fibrosis have improved dramatically. The newest drugs, known as potentiators, target a protein called cystic fibrosis transmembrane conductance regulator, which is mutated in people with the disease. Yet, while these medications can help some people with cystic fibrosis, they are far […]

Imagine a molecule powerful enough to reconfigure your mind and body — a molecule that makes your bones and muscles grow, makes your organs behave differently and alters your mind and your mood. Such is the power of sex hormones — estrogen, progesterone and testosterone. These naturally occurring chemicals are […]

Scientists at Colorado State University (CSU) and Tokyo Institute of Technology (Tokyo Tech) have developed a new powerful tool called a “frankenbody”, for imaging protein dynamics in living cells.
