Researchers detect age-related differences in DNA from blood

Researchers have discovered age- and health-related differences in fragments of DNA found floating in the bloodstream (not inside cells) called cell-free DNA (cfDNA). These differences could someday be used to determine biological age — whether a person’s body functions as older or younger than their chronological age, the researchers say. In […]

Researchers restore breathing and partial forelimb function in rats with chronic spinal cord injuries

Millions of people worldwide are living with chronic spinal cord injuries, with 250,000 to 500,000 new cases each year—most from vehicle crashes or falls. The most severe spinal cord injuries completely paralyze their victims and more than half impair a person’s ability to breathe. Now, a breakthrough study published in Nature […]

First Oral Immunotherapy for Peanut Allergy Gets Closer to FDA Vote

After learning their son Andrew had a serious peanut allergy, Jennifer and Daniel Ayala did everything they could to protect him, from becoming master label readers to sending him to birthday parties with his own treats. Still, there were times Andrew accidentally ingested peanut, most often from an outside food […]

Genome Offers Clues to Esophageal Cancer Disparity

A change in the genome of Caucasians could explain much higher rates of the most common type of esophageal cancer in this population, a new study finds. It suggests a possible target for prevention strategies, which preliminary work suggests could involve flavonoids derived from cranberries. Flavonoids are a class of […]

Study finds elevated risk of certain rare blood cancers after chemotherapy for most solid tumors

Findings from a new study by researchers at the National Cancer Institute (NCI) show that patients treated with chemotherapy for most solid tumors during 2000–2014 experienced an increased risk of therapy-related myelodysplastic syndrome/acute myeloid leukemia (tMDS/AML). The study, which used U.S. population-based cancer registry data from NCI’s Surveillance, Epidemiology, and […]

Mapping the brain, cell by cell

MIT chemical engineers and neuroscientists have devised a new way to preserve biological tissue, allowing them to visualize proteins, DNA, and other molecules within cells, and to map the connections between neurons. The researchers showed that they could use this method, known as SHIELD, to trace the connections between neurons […]

Graduate degree bolsters clinician’s research into preventing blindness

The technology for an eye specialist to review a picture of a patient’s eye taken miles away to screen for eye disease has been around for decades. Yet, less than half of Wisconsin adults with diabetes, who are particularly vulnerable to vision-threatening diseases, get annual eye screenings. Dr. Yao Liu, […]

Molecule predicts patient’s ability to survive melanoma

Doctors may be able to assess the survival rates of melanoma patients following the discovery of a molecule that allows the cancer to spread from the skin to other parts of the body. University of Queensland researchers hope that targeting this molecule may offer a way to stop the cancer from […]

Lithium might work as an anti-aging drug, depending on your genes

There is growing evidence that lithium could be re-purposed as an anti-aging drug, and a new study from King’s College London suggests that lithium’s protective effects are due to a slowing down of the molecular aging process in cells. The research, published in Neuropsychopharmacology, also finds some individuals may benefit from […]

2,000 human brains yield clues to how genes raise risk for mental illnesses

Artificial intelligence model improves prediction six-fold. It’s one thing to detect sites in the genome associated with mental disorders; it’s quite another to discover the biological mechanisms by which these changes in DNA work in the human brain to boost risk. In their first concerted effort to tackle the latter, […]
