By Maria Cohut Fact checked by Jasmin Collier New observational research indicates an association between a lower risk of precancerous growths (adenoma) in the bowel and yogurt consumption patterns — in men, at least. Estimates from the National Cancer Institute (NCI) indicate that there will be 145,600 new cases of colorectal cancer in the United States...

How bacteria kill host cells from the inside
by Public Library of Science Phagocytosed P. aeruginosa PAO1 first resides in a vacuole, before escaping the phagosome and promoting macrophage lysis. Live imaging of macrophages infected with fluorescent P. aeruginosa allows to follow the lysis of a specific macrophage (white arrow on the picture). MgtC and OprF act positively on the expression of T3SS, which is involved in cell...

Researchers identify enzyme that suppresses immune system in breast cancer
by Duke University Medical Center Immunotherapies have transformed cancer care, but their successes have been limited for reasons that are both complex and perplexing. In breast cancer especially, only a small number of patients are even eligible to undergo treatment with immunotherapies, and most see little benefit. But in a pre-clinical study led by the Duke Cancer Institute, researchers outlined...

Spasers: Nanoscale Lasers Small Enough to Destroy Cancer Cells from Within
Lasers are known to do remarkable things in medicine, but their use in targeting diseased tissue is not as widespread as everyone expected it to be decades ago. One issue is that lasers are pretty indiscriminate and traditionally have beams that are still too large for extremely fine work. Researchers at the University of Arkansas for Medical Sciences...

Deadly tick-borne virus cured with experimental flu drug, in mice
Only a few cases of the newly discovered Bourbon virus have been reported, and two of them ended in death, partly because no specific treatments are available for the tick-borne illness. Now, researchers at Washington University School of Medicine in St. Louis have identified an experimental antiviral drug that cures mice infected with the potentially lethal virus. The drug, favipiravir, is approved in Japan but not the...

Scientists have ‘cracked the code’ of the human brain and can create a 3D-reconstruction of someone’s face using the information stored in a person’s mind when they think of them
University of Glasgow experts investigated how we remember each other’s faces Researchers had people compare their memory of faces with similar 3D models From this they could work out which features our brains use to identify faces The findings could have applications to AI, gaming and eyewitness testimony It’s great to spot a familiar face — and now researchers have ‘cracked the code’...

Early research shows a way to develop effective therapies against pancreatic cancer
by Mariano Barbacid, The Conversation Pancreatic ductal adenocarcinoma (PDAC), the most common form of pancreatic cancer, is the fifth most common cause of death from cancer in the UK and the third in the United States. Deaths from PDAC outnumber those from breast cancer despite the significant difference in incidence rates. Late diagnosis and ineffective treatments are the most important reasons for these bleak...

Your nose knows when it comes to stronger memories
by New York University Memories are stronger when the original experiences are accompanied by unpleasant odors, a team of researchers has found. The study broadens our understanding of what can drive Pavlovian responses and points to how negative experiences influence our ability to recall past events. “These results demonstrate that bad smells are capable of producing memory enhancements in both adolescents...

More Immersive VR isn‘t necessarily more Effective, Study Finds
Contrary to the common sense view that more immersive virtual reality (VR) environments provide better outcomes, a new study published in the journal Cyberpsychology, Behavior, and Social Networking has found that more basic designs could actually be preferable, at least under some conditions. In the study, 129 students from a western university were split into three groups where their interactions with a virtual agent in...
