New gene for bipolar disorder discovered

Researchers identified two new gene regions associated with bipolar disorder and confirmed three existing ones through a massive international collaboration. The study analyzed genetic data from over 9,400 patients and found that these genes work together with environmental factors to contribute to the disease.

No one likes a copycat, no matter where you live

Researchers found that young children in different cultures do not fully grasp the concept of intellectual property until around age 5 or 6. In contrast, older children and adults across cultures view copying as negative. The study suggests that cultural differences may not be as significant as previously thought.

Timid jumping spider uses ant as bodyguard

A timid jumping spider uses the scent of ants as a defense mechanism against spitting spiders, positioning itself near ant nests for protection. However, this protection also comes with a cost, as jumping spiders are preyed upon by their savior species, the weaver ant.

Promoting love can punish sales

A new study found that reminders of relationships consumers don't have can lead to restrictions on indulgent spending, choosing lower-end brands and opting for healthier options. This effect is particularly pronounced during holidays and wedding season when relationship portrayals are prominent in advertisements.

Cellular alchemy: Penn study shows how to make insulin-producing cells from gut cells

Scientists have made a breakthrough in treating type 1 and type 2 diabetes by successfully converting gut cells into functional insulin-producing cells. The new method involves introducing specific transcription factors into intestinal crypt cells, which can then produce insulin and improve hyperglycemia in diabetic mice.

National study reveals urban lawn care habits

A new national study found that urban lawn care practices vary significantly across cities, despite uniformity in appearance. The research suggests that local climate and social factors play a more significant role than initially expected, requiring tailored solutions to address environmental challenges. Understanding these patterns is...

Outside the body our memories fail us

Studies show that when participants experience an 'out-of-body' illusion, their memories are fragmented and stored improperly. The research suggests a close relationship between body experience and memory, with implications for understanding psychiatric conditions such as PTSD and schizophrenia.

Doctors often uncertain in ordering, interpreting lab tests

A national survey of primary care physicians found they often experience uncertainty in ordering and interpreting clinical laboratory tests, with missing results and confusing report formats being major challenges. Physicians reported that improved electronic decision-support tools and access to lab personnel would help reduce this unc...

A shocking diet

Researchers identified a microbe that can take up electrons from minerals in soil and sediment using natural conductivity. The microbes rely on sunlight and iron to generate energy, but have developed an unusual strategy to reach the iron through naturally occurring conductive minerals.

Turing's theory of chemical morphogenesis validated 60 years after his death

Scientists from Brandeis University and the University of Pittsburgh validate Alan Turing's theory of morphogenesis, demonstrating that identical cell-like structures can differentiate into various patterns through intercellular reaction-diffusion. The research has implications for biological development, materials science, and soft ro...

Mongol Empire rode wave of mild climate, says study

A recent study using ancient tree rings reveals that the Mongol Empire's rapid expansion was facilitated by a period of unusually mild and wet weather in central Asia. The findings suggest that this favorable climate allowed for increased grass production, which in turn enabled the Mongols to build their powerful horse-riding army.
