New tumor model helps researchers treat pancreatic cancer

Patients diagnosed with pancreatic cancer face a poor prognosis because the tumor forms dense scar-like tissue that is difficult for chemotherapy drugs to penetrate, but a new model may help researchers develop new therapies. “More than 85 percent of pancreatic tumors form this fibrous tissue,” explained Assistant Professor Joshua Reineke of the South Dakota State […]

Mountain splendor? Scientists know where your eyes will look

Using precise brain measurements, Yale researchers predicted how people’s eyes move when viewing natural scenes, an advance in understanding the human visual system that can improve a host of artificial intelligence efforts, such as the development of driverless cars, said the researchers. “We are visual beings and knowing how the brain rapidly computes where to […]

Older people can come to believe their own lies

What happens when older adults lie? A new study suggests that in as little as 45 minutes they can come to believe it’s the truth. Associate professor of psychology Angela Gutchess and her colleagues published the research online in the journal Brain and Cognition. Gutchess and her collaborators used electroencephalography (EEG) to monitor the brain […]

Influenza A deliberately enhances levels of the human p53 protein to reduce anti-viral gene and protein expression

Genome editing technology is helping A*STAR scientists unravel how the Influenza A virus (IAV) exploits human anti-viral responses. IAV remains a key challenge for global health resources, not least because of wide variations in symptom severity experienced by different people, even when they are infected by the same strain. This implies that there are host […]

Got menopause? Healthy lifestyle now is crucial for heart health

A healthy lifestyle during the transition to menopause may offset the acceleration of atherosclerosis, the slow narrowing of the arteries that increases with age, according to new research in the Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association. Women participating in the Study of Women’s Health […]

Advanced imaging technology measures magnetite levels in the living brain

Investigators at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH) have used magnetoencephalography (MEG) – a technology that measures brain activity by detecting the weak magnetic fields produced by the brain’s normal electrical currents—to measure levels of the iron-based mineral called magnetite in the human brain. While magnetite is known to be […]
