In this episode of Bioscience Technology This Week, News Editor Christina Jakubowski highlights the role of the protein GSK-3 in brain development and also reports that running, regardless of duration or speed, reduces death risk.
Scientists report they can crank up insect aggression simply by interfering with a basic metabolic pathway in the insect brain. Their study, of fruit flies and honey bees, shows a direct, causal link between brain metabolism (how the brain generates the energy it needs to function) and aggression.
Frogs, dogs, whales, snails can all do it, but humans and primates can't. Regrow nerves after an injury, that is— while many animals have this ability, humans don't. But now, new research suggests that a small molecule may be able to convince damaged nerves to grow and effectively rewire circuits.
The relationship between saturated fat and type 2 diabetes may be more complex than previously thought, according a study that claims saturated fatty acids can be associated with both an increased and decreased risk of developing the disease, depending on the type of fatty acids present in the blood.
A team of scientists has developed an entirely non-invasive technique that provides a view of blood flow in the brain. The tool could provide powerful insights into strokes and possibly Alzheimer's disease.
There is good news in attempts to halt HIV by growing, in patients, new immune systems lacking a gene that led to the first—and only—cured HIV patient. Using hematopoietic (blood) stem cells possessing a CCR5 gene mutation that blocks CD4 T cell entry of HIV, Calimmune—led by Nobel Laureate David Baltimore—has, for one year, safely begun growing new immune systems in patients.
Eating baked or broiled fish once a week is good for the brain, regardless of how much omega-3 fatty acid it contains, according to researchers at the University of Pittsburgh School of Medicine. The findings add to growing evidence that lifestyle factors contribute to brain health later in life.
Effective new drugs and screening would make hepatitis C a rare disease by 2036, according to a computer simulation conducted by The University of Texas MD Anderson Cancer Center and the University of Pittsburgh Graduate School of Public Health.
Researchers have achieved a technical breakthrough that should result in speedier diagnosis of cancer and various pre-natal conditions. The key discovery lies in a new tool that allows researchers to load long strands of DNA into a tunable nanoscale imaging chamber in ways that maintain their structural identity and under conditions that are similar to those found in the human body.
University of Michigan Health System researchers revealed an obesity paradox among older Americans suffering from sepsis. In a study of 1,404 Medicare beneficiaries, heavier patients were more likely to survive the life-threatening infection that can lead to a stay in a hospital’s intensive care unit.
The body’s assailants are cleverer than previously thought. New research from Lund University in Sweden shows for the first time how bacteria in the airways can help each other replenish vital iron. The bacteria thereby increase their chances of survival, which can happen at the expense of the person’s health.
The tiny addition of a chemical mark atop a gene that is well known for its involvement in clinical depression and posttraumatic stress disorder can affect the way a person’s brain responds to threats, according to a new study.
A large DNA analysis of people with and without pancreatic cancer has identified several new genetic markers that signal increased risk of developing the highly lethal disease, scientists report.
Researchers report that dietary capsaicin– the active ingredient in chili peppers– produces chronic activation of a receptor on cells lining the intestines of mice, triggering a reaction that ultimately reduces the risk of colorectal tumors.
New research suggests that microRNAs may be able to relay valuable information about damage to the heart: Scientists have linked an increase in certain microRNAs circulating in the blood with injury to cardiac muscle.
Scientists have discovered that a compound isolated from the plant protects cells from altered molecular pathways linked to Alzheimer’s, Parkinson’s and the neurodegeneration that often follows a stroke.
A water ban that had hundreds of thousands of people in Ohio and Michigan scrambling for drinking water has been lifted, Toledo's mayor announced Monday.
The nation's top infectious disease official says there's hope that a vaccine against Ebola will be available as early as next July. Dr. Anthony Fauci of the National Institutes of Health says such a preventive vaccine has been successfully tested with monkeys.
Research at New York University is paving the way for a breakthrough that may prevent brain damage in civilians and military troops exposed to poisonous chemicals—particularly those in pesticides and chemical weapons. The research outlines the advancement in detoxifying organophosphates, which are compounds commonly used in pesticides and warfare agents.
A new study has found that a peptide called caerulein can convert existing cells in the pancreas into those cells destroyed in type 1 diabetes-insulin-producing beta cells.
Harnessing a natural process in the body that pumps lethal doses of copper to fungi and bacteria shows promise as a new way to kill infectious microbes, a team of scientists report.
Much of the liver’s metabolic function is governed by circadian rhythms—our own body clock—and UC Irvine researchers have now found two independent mechanisms by which this occurs. The study reveals new information about the body clock’s sway over metabolism and points the way to more focused drug treatments for liver disease and such metabolic disorders as obesity and diabetes.
A new study gives insight into the relationship between depression and dementia. The current study, which involved 1,764 people from the Religious Orders Study and the Rush Memory and Aging Project, indicates that the association of depression with dementia is independent of dementia-related brain changes.
Exposure of pregnant mice to the pesticide DDT is linked to an increased risk of obesity, diabetes, high cholesterol, and related conditions in female offspring later in life, according to a study led by the University of California, Davis.
In what is believed to be the largest genetic analysis of what triggers and propels progression of tumor growth in a common childhood blood cancer, researchers report that they have identified a possible new drug target for treating the disease.
