Geneticists have solved a century-old mystery by discovering a remarkable mechanism that enables plants to count their chromosomes. Their ability to detect imbalances in male and female contributions to the next generation determines their progeny's viability and fertility.
A new study details the minute changes -- down to the level of individual atoms -- that cause a particular protein to form cell-damaging clumps associated with ALS and other diseases.
Doctors have long treated heart attacks, improved asthma symptoms, and cured impotence by increasing levels of a single molecule in the body: nitric oxide. The tiny molecule can change how proteins function. But new research featured in Molecular Cell suggests supplementing nitric oxide--NO--is only the first step. Researchers have discovered previously unknown enzymes in the body that convert NO into 'stopgap' molecules--SNOs--that then modulate proteins. The newly discovered enzymes help NO have diverse roles in cells.
Data collected during a long-term health study provides additional evidence for a link between increased risk of cancer in individuals with advanced gum disease, according to a new collaborative study led by researchers at the Johns Hopkins Bloomberg School of Public Health, Johns Hopkins Kimmel Cancer Center and Tufts University School of Medicine and Cancer Center.
New researcher shows how Zika virus infection in five pregnant rhesus monkeys caused placental tissues to become thickened and inflamed, resulting in less oxygen being transported across the placenta and to the baby.
It is easier to spread the influenza virus (flu) than previously thought, according to a new study released today. People commonly believe that they can catch the flu by exposure to droplets from an infected person's coughs or sneezes or by touching contaminated surfaces. But, new information about flu transmission reveals that we may pass the flu to others just by breathing.
Major beer companies have rolled out marketing campaigns and products -- such as 'fan cans,' store displays, and billboard ads -- that pair beer with university colors, mascots, and logos. Research published in the January 2018 issue of Psychological Science shows that such campaigns may enhance the motivational significance of marketed beer brands, especially for students who identify strongly with their university. The researchers conclude that this effect could potentially increase underage students' alcohol consumption.
A new Michigan State University study is helping to answer a pressing question among scientists of just how close mice are to people when it comes to researching cancer. The findings reveal how mice can actually mimic human breast cancer tissue and its genes, even more so than previously thought, as well as other cancers including lung, oral and esophagus.
Researchers have identified evidence of early Chronic Traumatic Encephalopathy (CTE) brain pathology after head impact -- even in the absence of signs of concussion. Early indicators of CTE pathology not only persisted long after injury but also spread through the brain, providing the best evidence to date that head impact, not concussion, causes CTE.
Researchers developed a new mathematical tool to validate and improve methods used by medical professionals to interpret results from clinical genetic tests. The work was published this month in Genetics in Medicine.
