Breaking the Egg Barrier: A Sperm Story
Yale Physiology researchers found that sperm hyperactivation is an evolutionary conserved mechanism to penetrate the egg barriers, used as early as in monotreme but diverged to use it as a way of navigation in the female reproductive tract when it become more complicated in placenta mammals.
Yale Physiology researchers discover how blind worms "see" the color blue
The laboratory of Dr. Michael Nitabach discovered that C. elegans, despite lacking eyes and opsin genes, can discriminate between colors to guide foraging decisions. The study is published in the Science journal (https://science.sciencemag.org/content/371/6533/1059) and is accompanied by a perspective article by Lauren Neal, Leslie Vosshall (https://science.sciencemag.org/content/371/6533/995)Source: How Do Blind Worms See the Color Blue?

Yale researchers help restore hormonal balance disrupted in metabolic diseases
Now Yale scientists report March 4 in the journal Nature that they have discovered the molecular mechanisms that trigger metabolic imbalance between these two distinct but linked processes, a finding with implications for the treatment of diabetes and non-alcoholic fatty liver disease (NAFLD).
New Drugs on the Horizon for Stroke and Hydrocephalus
Kristopher Kahle, MD, assistant professor of neurosurgery and of cellular and molecular physiology at Yale School of Medicine, recently published a study describing a new compound that could reduce swelling in the brain caused by stroke or hydrocephalus.
Yale Researchers Find That Ubiquitous Protein Plays Lead Role in Cell Survival
Yale researchers have discovered that the protein polycystin 2 protects against cell death, making it a potential target for therapies to treat a variety of diseases of the liver and kidneys, as well as for brain aneurysms, heart disease, and cancer.
Molecular ‘Doormen’ Open the Way to Potential Obesity Treatment
In obese individuals, cellular "doormen" open the gates far too wide in certain key fat cells, known as visceral fat cells, letting in too many carbohydrates without first burning off lipids. This leads to a ballooning of the size of visceral fat cells in the belly.
Molecular Control of Neurotransmitter Linked to Autism Described
In two new papers published Oct. 15 in Science Signaling, researchers from Yale, France, Japan, and the United Kingdom have zeroed in on a molecular mechanism crucial to normal brain development, which, when impaired, causes autism-like symptoms in mice.
Gracheva Receives Presidential Early Career Award
Elena Gracheva, PhD, associate professor of cellular and molecular physiology and of neuroscience, has been awarded the Presidential Early Career Award for Scientists and Engineers (PECASE). The White House announced its complete list of recipients, including two additional Yale faculty members, on July 2.
Yale-led Study Reveals Biology of Leptin, the Hunger Hormone
In a new study, Yale researchers offer insight into leptin, a hormone that plays a key role in appetite, overeating, and obesity. Their findings advance knowledge about leptin and weight gain, and also suggest a potential strategy for developing future weight-loss treatments, they said.
New Strategy for Untreatable Kidney Disease: Targeting Cell Energy
The best hope for people with an inherited form of kidney disease that causes kidney failure is dialysis or a kidney transplant. But a study led by Yale researchers reveals a potential strategy for developing new drug therapies for these patients.
