When it comes to climate change, government leaders and politicians must begin to think beyond their term limits and lifetimes. They must ask themselves not how they can serve their voters, but rather how they can contri...

Scientists and engineers have invented a range of bioactive 'tissue papers' made of materials derived from organs that are thin and flexible enough to even fold into an origami bird. The new biomaterials can potentially ...

Energy loss due to scattering from material defects is known to set limits on the performance of nearly all technologies that we employ for communications, timing, and navigation. In micro-mechanical gyroscopes and accel...

Living near fast-food restaurants and supermarkets has little impact on an individual's body mass index, according to new research. The researchers used results from the largest national study ever conducted of the conne...

In a randomized controlled trial, researchers studied low-income adults newly covered by a primary care program to determine if a cash incentive could encourage them to make an initial visit to a primary care provider. A...

Most of the nuclear reactions that drive the nucleosynthesis of the elements in our universe occur in very extreme stellar plasma conditions. This intense environment found in the deep interiors of stars has made it near...

Puppies receiving the most care from their mothers grow into adult dogs that lack the impulse control and problem solving ability of a successful guide dog

DNA from ancient cod bones shows Vikings freeze-dried Arctic cod for serving up on European menus 300 years earlier than we thought

In an animal model of obesity and breast cancer, tumor cells in obese animals but not lean animals had especially sensitive androgen receptors, allowing these cells to magnify growth signals from the hormone testosterone...

A new study identifies genes that are necessary in cancer cells for immunotherapy to work, addressing the problem of why some tumors don't respond to immunotherapy or respond initially but then stop as tumor cells develo...

An antenna-like structure on cells, once considered a useless vestige, can cause defects in the brain's wiring similar to what's seen in autism, schizophrenia, and other disorders. In the lab, scientists prevented defect...

Prenatal brain development is a crucial period, and as new research has found, even small alterations to the way brain cells develop can have significant effects later in life. Scientists have shed light on the role that...

Media portrayals of pregnant, postpartum women unrealistic, women said in a new study. Exposure to unrealistic images and messages fostered a host of negative emotions, such as self-consciousness about their bodies and f...

For the first time, scientists have simulated the reverse of the common effect where cold water runs away from heat, and the result could keep electronics cool

Closthioamide, discovered in 2010, might eventually offer an alternative for current drugs that are becoming less effective against gonorrhoea, report investigators.

Researchers have devised a new way to monitor sleep without any kind of sensors attached to the body. Their sensor uses low-power radio waves that detect small changes in body movement caused by the patient's breathing a...

Computer analysis of oxygen levels in the blood during sleep could -- by itself -- provide an easy, relatively inexpensive and sufficiently reliable way to determine which children who snore habitually could benefit from...

Two research teams have made structures that could help conceal objects from daylight - taking the next step towards making the visible, invisible. Recent progress draws on advances in so-called metamaterials, which are ...

By the end of this century, temperatures in South Asia -- a region where about one-fifth of the world's population lives -- could become too hot and humid for people to survive, according to a new study.

From the gecko's sticky feet to the sophisticated sniffing ability of dogs, nature often provides inspiration for new materials and technologies. Recently, nature has inspired something that could help many people see li...

Researchers have demonstrated the potential of a new PET tracer, Carbon-11 labeled sarcosine (11C-sarcosine), for imaging prostate cancer, and set the stage for its possible use in monitoring other cancers.

A research team at the University of Central Florida has demonstrated the fastest light pulse ever developed, a 53-attosecond X-ray flash.
