Some mutations allowing humans to fend off deadly infections also make us more prone to certain inflammatory and autoimmune diseases, such as Crohn's. Researchers describe how ancestral origins impact the likelihood that people of African or Eurasian descent might develop immune-related diseases.

A method with roots in AI uncovers how humans make choices in groups and social media
Using a mathematical framework with roots in artificial intelligence and robotics, UW researchers were able to uncover the process for how a person makes choices in groups. And, they also found they were able to predict a person's choice more often than more…
The desert-dwelling Namib desert beetle "eats fog", harvesting water from the air through its unique, grooved body which directs fog droplets into the beetle's mouth. Microscopic features on the beetle aid evacuation of lubricating film, which facilitates water collection.

Anthrax may be the next tool in the fight against bladder cancer, suggests new study based on human tumor samples and dogs with bladder cancer. Researchers combine the anthrax toxin with a growth factor to kill bladder cancer cells and tumors, without harming the normal cells in the bladder.

Anthrax may be the next tool in the fight against bladder cancer @PurdueRP
Anthrax may soon help more people win the fight against bladder cancer, which the U.S. Centers for Disease Control and Prevention says strikes about 72,000 Americans each year and kills about 16,000, and is one of the most expensive cancers to treat.

Most dolphins are 'right-handed', say researchers — Bottlenose dolphins found to have an even stronger right-side bias than 90% of humans who are right-handed. The team said the right-side bias might help dolphins swallow food and pick up sensory information.

Effects of microbiota-directed foods in gnotobiotic animals and undernourished children
Childhood malnutrition is accompanied by growth stunting and immaturity of the gut microbiota. Even after therapeutic intervention with standard commercial complementary foods, children may fail to thrive. Gehrig et al. and Raman et al. monitored metabolic…

Modeling other minds: Bayesian inference explains human choices in group decision-making
To make decisions in a social context, humans have to predict the behavior of others, an ability that is thought to rely on having a model of other minds known as “theory of mind.” Such a model becomes especially complex when the number of people one simultaneously…
Young fish can be drawn to degraded coral reefs by loudspeakers playing the sounds of healthy reefs. Broadcasting healthy reef sound doubled the total number of fish arriving onto experimental patches of reef habitat, as well as increasing the number of species present by 50 per cent.

滑雪，下一波席卷中国的运动热潮？
冬天像往常一样随着咆哮的西伯利亚寒风降临北京。寒流呼啸着穿过胡同和环城公路，钻进你家门缝，钻进你的衣衫。那是12月初。名为“大雪”的节气已经来临，到了该下大雪的时候。 但是不会有雪，北京几乎从来不下雪。2018年的最后几天是清朗的，夜晚的点点星光刺穿了这座城市的橙色圆顶。雪并不重要。重要的是寒冷，现在，这里的人们可以搞事情了。 那是周六，南山滑雪场开张了。它是距北京一小时车程的10个滑雪场之一。滑雪场里挤满了人。在过去的四天，这里的32门雪炮一直在发射着可以乱真的蓬松晶体，工人们推着它们覆盖了几座山坡。…
