Some nerve cells in the inner ear can signal tissue damage in a way similar to pain-sensing nerve cells in the body, according to new research from Johns Hopkins. If the finding, discovered in rats, is confirmed in humans, it may lead to new insights into hyperacusis, an increased sensitivity to loud noises that can lead to severe and long-lasting ear pain.

Institutional and cultural pressures lead scientists to avoid risk-taking and choose inefficient research strategies, conclude two University of Chicago studies analyzing millions of journal articles and patents.
Our chromosomes contain all of our genetic information, and it’s up to telomeres – structures of proteins that cap off and protect our DNA at the tips of chromosomes – to preserve the vital instructions necessary for life. There are even specific molecules like TERRA (Telomeric repeat-containing RNA) that exist specifically to regulate telomeres and promote chromosome end protection. Now, a new study has found that TERRA can be found outside of cells and serve as a potentially important cell signaling molecule that induces an inflammatory response, and this activity may play an important role in the development of cancer.
The hippocampus, a brain structure known to play a role in memory and spatial navigation, is essential to one’s ability to recognize previously encountered events, objects, or people – a phenomenon known as recognition memory – according to new research from the departments of Neurosurgery and Psychology in the Perelman School of Medicine at the University of Pennsylvania. Their work is published in PNAS.

According to a surprising new study published in the Proceedings of the National Academy of Sciences on Monday, a decades-long decline in the death rate of middle-aged white Americans (age 45 to 54) has reversed in recent years. The causes are not the big killers such as heart disease and diabetes but an epidemic of suicides and substance abuse. The study was done by Nobel-winning researchers Angus Deaton and Anne Case of Princeton University.

A new study led by Colorado State University finds that the West Nile virus is killing birds — more so than previously thought — in the short- and long-term.
Chronic inflammation, closely associated with frailty and age-related diseases, is a hallmark of aging. Mayo Clinic researchers have discovered that inhibiting key enzyme pathways reduces inflammation in human cells in culture dishes and decreases inflammation and frailty in aged mice.
An international team of researchers, led by Penn State, has developed ultrasensitive gas sensors based on the infusion of boron atoms into the tightly bound matrix of carbon atoms known as graphene.

A study in the Nov. 2 issue of Proceedings of the National Academy of Sciences is the first to fully document the demographic impacts of West Nile virus on North American bird populations. Data from bird-banding stations shows more species were hit than suspected, and half of those have yet to recover.
A Tufts University chemist has discovered a way to select specific surfaces of single-crystal ice for study, a long-sought breakthrough that could help researchers answer essential questions about climate and the environment.
New research by a team of scientists led by Catherine Markham, PhD, a Stony Brook University anthropologist, reveals that intermediate-sized groups provide the most benefits to wild baboons.
Activating an enzyme that sounds an alarm for the body’s innate immune system causes two lethal autoimmune diseases in mice, while inhibiting the same enzyme rescues them, UT Southwestern Medical Center researchers report.

Prof. Avihai Danon has discovered plants’ “off” switch for producing starch, 50 years after the “on” switch was found. Further, his team at the Weizmann Institute learned that the on and off switches are active at the same time, which is like driving while pressing both the gas and the brakes – but why?
A new study conducted by researchers from three institutions has examined in the role of negative citations in academic publishing. The researchers found that one in 50 citations from a major academic journal contained criticism of previous work.
Researchers find that permafrost organic material is so biodegradable that as soon as it thaws, the carbon is almost immediately consumed by single-cell organisms called microbes and then released back into the air as carbon dioxide, feeding the global climate cycle. Their findings are laid out in an article published today by the Proceedings of National Academy of Sciences.
