There may be a link between exposure to light during pregnancy and fetal brain development. New findings by researchers at Umeå University, Sweden, working in collaboration with American colleagues, may provide better understanding of certain neurological diseases later in life. “Ultimately, this discovery may open up possibilities for using the right kind of light stimulation […]

A highly contagious disease originating far from America’s shores triggers deadly outbreaks that spread rapidly, infecting the masses. Shots are available, but a divided public agonizes over getting jabbed. Sound familiar? Newly digitized records—including a minister’s diary scanned and posted online by Boston’s Congregational Library and Archives—are shedding fresh light on devastating outbreaks of smallpox […]
In many ways, our brain and our digestive tract are deeply connected. Feeling nervous may lead to physical pain in the stomach, while hunger signals from the gut make us feel irritable. Recent studies have even suggested that the bacteria living in our gut can influence some neurological diseases. Modeling these complex interactions in animals […]
Most diseases are caused by aberrant cell signaling processes, and basic research in cell signaling is needed to identify targets for future therapeutic approaches, especially in cases where no cures or effective treatments are currently available. Cellular optogenetics uses light to precisely control cell signaling in space and over time, making it an invaluable technique […]
The world’s population is aging rapidly, presenting an urgency to address the health problems of the aged. Critical insights on these problems can be gained by examining how the aging process has been shaped over evolutionary time, and how it is influenced by different environments and lifestyles. In a special edition of Philosophical Transactions of […]
University of Cincinnati researchers have found that certain treatments for cancer may increase the chance of death if they contract COVID-19. These findings from a multicenter study, presented at the European Society for Medical Oncology Virtual Congress 2020, shed light on ways standard anti-cancer treatments may impact outcomes for patients with both cancer and the […]
Outdoor light at night was linked to a higher risk of breast cancer in a study published in the International Journal of Cancer. For the study, investigators analyzed residential outdoor light at night estimated from satellite imagery in 1996 and assessed rates of breast cancer over 16 years of follow-up in 186,981 postmenopausal women. Compared […]
The coronavirus pandemic notched up another round of record death tolls in the United States and Europe, dousing the optimism of US President Donald Trump who insisted there was light at the end of the tunnel. The virus has now killed more than 87,000 people and infected over 1.5 million, according to an AFP tally […]
For over a century, Alzheimer’s disease has confounded all attempts to treat it. But in recent years, perplexing experiments using flickering light have shown promise. Now, researchers have tapped into how the flicker may work. They discovered in the lab that the exposure to light pulsing at 40 hertz—40 beats per second—causes brains to release […]
