Yale study: How antibodies access neurons to fight infection

Yale scientists have solved a puzzle of the immune system: how antibodies enter the nervous system to control viral infections. Their finding may have implications for the prevention and treatment of a range of conditions, including herpes and Guillain-Barre syndrome, which has been linked to the Zika virus. (more…)

UCLA scientists test new strategy that could help fight ovarian cancer

Approach borrows from technique of inhibiting protein fibers that cause Alzheimer’s and Parkinson’s diseases

UCLA scientists have developed a promising novel method to treat gynecologic tumors. The approach focuses on a protein called p53, which is commonly mutated in women who have high-grade serous ovarian cancer, the deadliest form of reproductive cancer. In many women with the disease, the cancer is very advanced by the time it is diagnosed and is therefore difficult to treat. (more…)

No way around it: Reducing emissions will be the primary way to fight climate change, UCLA-led study finds

Climate engineering won’t sufficiently stem global warming

orget about positioning giant mirrors in space to reduce the amount of sunlight being trapped in the earth’s atmosphere or seeding clouds to reduce the amount of light entering earth’s atmosphere. Those approaches to climate engineering aren’t likely to be effective or practical in slowing global warming. (more…)

How a Shape-shifting DNA-repair Machine Fights Cancer

Berkeley Lab’s Advanced Light Source reveals inner-workings of essential protein found throughout life.

Maybe you’ve seen the movies or played with toy Transformers, those shape-shifting machines that morph in response to whatever challenge they face. It turns out that DNA-repair machines in your cells use a similar approach to fight cancer and other diseases, according to research led by scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).

As reported in a pair of new studies, the scientists gained new insights into how a protein complex called Mre11-Rad50 reshapes itself to take on different DNA-repair tasks. (more…)

Exercise reorganizes the brain to be more resilient to stress

Physical activity reorganizes the brain so that its response to stress is reduced and anxiety is less likely to interfere with normal brain function, according to a research team based at Princeton University.

The researchers report in the Journal of Neuroscience that when mice allowed to exercise regularly experienced a stressor — exposure to cold water — their brains exhibited a spike in the activity of neurons that shut off excitement in the ventral hippocampus, a brain region shown to regulate anxiety.

Fighting Words: Violent Political Rhetoric Fuels Violent Attitudes

ANN ARBOR, Mich.— Political leaders regularly promise to “fight” for noble causes and “combat” pressing problems. They declare “war” on social problems, such as poverty, disease, drugs and terrorism.

This violent political rhetoric—whether politicians intend to or not—can enflame violent attitudes in many Americans, especially those predisposed to behave aggressively in daily life, according to new University of Michigan research involving three studies. (more…)
