Natural compound found in broccoli reawakens the function of potent tumor suppressor



Posted: 16 May 2019 11:29 AM PDT


Long associated with decreased risk of cancer, broccoli and other cruciferous vegetables -- the family of plants that also includes cauliflower, cabbage, collard greens, Brussels sprouts and kale -- contain a molecule that inactivates a gene known to play a role in a variety of common human cancers. A new study demonstrates that targeting the gene, known as WWP1, with the ingredient found in broccoli suppressed tumor growth in cancer-prone lab animals.


Scientists find new type of cell that helps tadpoles' tails regenerate



Posted: 16 May 2019 11:29 AM PDT


Researchers have uncovered a specialized population of skin cells that coordinate tail regeneration in frogs. These 'Regeneration-Organizing Cells' help to explain one of the great mysteries of nature and may offer clues about how this ability might be achieved in mammalian tissues.


Brain changes in autism traced to specific cell types



Posted: 16 May 2019 11:29 AM PDT


Changes in gene activity in specific brain cells are associated with the severity of autism in children and young adults with the disorder, according to a new study.


Brain's insular cortex processes pain and drives learning from pain



Posted: 16 May 2019 11:28 AM PDT


Neuroscientists have discovered an area of the brain, the insular cortex, that processes painful experiences and thereby drives learning from aversive events.


How we make complex decisions



Posted: 16 May 2019 11:28 AM PDT


Neuroscientists have identified a brain circuit that helps break complex decisions down into smaller pieces. The study sheds light on how the brain reasons about probable causes of failure after a hierarchy of decisions.


Galaxy blazes with new stars born from close encounter



Posted: 16 May 2019 08:46 AM PDT


The irregular galaxy NGC 4485 shows all the signs of having been involved in a hit-and-run accident with a bypassing galaxy. Rather than destroying the galaxy, the chance encounter is spawning a new generation of stars, and presumably planets.


Bedbugs evolved more than 100 million years ago



Posted: 16 May 2019 08:46 AM PDT


Bedbugs -- some of the most unwanted human bed-mates -- have been parasitic companions with other species aside from humans for more than 100 million years, walking the earth at the same time as dinosaurs.


Nearly a quarter of West Antarctic ice is now unstable



Posted: 16 May 2019 08:46 AM PDT


In only 25 years, ocean melting has caused ice thinning to spread across West Antarctica so rapidly that a quarter of its glacier ice is now affected, according to a new study.


Heavily processed foods cause overeating and weight gain, study finds



Posted: 16 May 2019 08:45 AM PDT


People eating ultra-processed foods ate more calories and gained more weight than when they ate a minimally processed diet, according to results from a new study. The difference occurred even though meals provided to the volunteers in both the ultra-processed and minimally processed diets had the same number of calories and macronutrients.


Surprising research result: All immature cells can develop into stem cells



Posted: 16 May 2019 07:14 AM PDT


A new study challenges traditional knowledge of stem cell development. The study reveals that the destiny of intestinal cells is not predetermined, but instead determined by the cells' surroundings. The findings may make it easier to manipulate stem cells for stem cell therapy.


Australian islands home to 414 million pieces of plastic pollution



Posted: 16 May 2019 06:08 AM PDT


A survey of plastic pollution on Australia's Cocos (Keeling) Islands has revealed the territory's beaches are littered with an estimated 414 million pieces of plastic debris. The study estimated beaches on the Indian Ocean islands are littered with 238 tons of plastic, including 977,000 shoes and 373,000 toothbrushes.
