A study found that individuals with chronic kidney disease who have a heart-healthy lifestyle are less likely to develop kidney failure. Those with four ideal factors for life's simple 7 tool had nearly half their risk cut, while those with five ideal factors didn't develop kidney failure.
Researchers found that mosquitoes may be responding to an immune challenge rather than manipulating their behavior to transmit malaria parasites. Mosquitoes will wait to feed until the parasites mature and migrate to the salivary glands, but this response is also seen in non-infected mosquitoes.
A new study found that a spike in acetylcholine in the right prefrontal cortex activates response to signals, suggesting a potential brain mechanism for switching between behaviors. The findings have implications for treating disorders such as obsessive-compulsive disorder and autism.
A new study published in the New England Journal of Medicine found that tonsil/adenoid surgery improved behavior, quality of life, and other symptoms in children with obstructive sleep apnea. However, there was no significant difference seen in attention and executive function between the treatment groups.
A study found that early removal of adenoids and tonsils can improve behavior, sleep apnea symptoms, and quality of life in children with mild to moderately severe sleep apnea. However, it did not show a significant improvement in attention and executive functioning.
A new method developed by Disney Research enables a humanoid robot to receive an object handed to it by a person with natural, human-like motion. By rapidly searching a database of human motion, the robot can predict where the human plans to make the handoff and move its arm accordingly.

A new study from MIT's Marta González and Christian Schneider found that people in Chicago and Paris make secondary trips in a consistent manner, with only 17 out of 1 million possible trip sequences used. This pattern, or 'motif,' indicates that individuals plan ahead and avoid revisiting locations to optimize travel time and distance.

Artificially intelligent game bots created by the University of Texas at Austin have won the BotPrize competition, scoring a humanness rating of 52% compared to humans' average of 40%. The winning bots use a two-pronged approach to mimic human behavior, combining direct modeling with neuroevolution.
Researchers found that chronic stress predicts greater increases in body weight over time in both black and white girls. However, the negative effect of chronic stress on black girls' weight may explain racial disparities in obesity levels. The study suggests stress may play a role in the obesity epidemic and racial disparities.
Researchers have observed dominance relationships among adolescent male chimpanzees in the Ngogo community, a large chimp community in Uganda with over 150 members. The study found that pant grunts are used to calm hostilities and establish dominance hierarchies, which is rare for this age group.
The article explores how terrorist attacks can lead to an increase in fatal traffic accidents, particularly in regions with well-developed infrastructure that encourages driving. The study found that the New York area saw a significant increase in car traffic after the 9/11 attacks, while other states did not experience the same surge.
A new study finds that post-menopausal women's eating behaviors associated with short-term weight loss are not effective or sustainable for the long term. Strategies such as increasing fruit and vegetable consumption, and decreasing meat and cheese intake, may improve long-term weight loss outcomes.

Research published in PLOS ONE found that autistic children who received a pet scored higher in 'offering to share' and 'offering comfort' categories after the pet arrived compared to before. Participants who had lived with pets since birth showed weaker relationships with their pets.
Scientists have successfully controlled monkey behavior using optogenetics by activating specific brain cells with blue light. This breakthrough could lead to the development of therapeutic treatments for neurological disorders such as Parkinson's disease and depression.
Research suggests that dualist philosophy can lead to reckless attitudes towards health and exercise, and a preference for unhealthy diet. People primed with dualist beliefs also reported stronger mind-body separation, viewing bodies as disposable vessels.
A new study finds that mice have a unique neural circuitry for processing instinctually important smells like those associated with predators. The TAAR-expressing neurons form an independent olfactory subsystem, distinct from the more common olfactory receptor neurons, which detect a broader range of smells.
