Hospital patients with dementia and other causes of confusion have longer stays and worse treatment outcomes than people without the condition, new research has found.

Researchers have discovered a whole genome duplication during the evolution of spiders and scorpions.

Like tourist season, wildfire season is also in full swing in British Columbia. Whereas tourists are welcomed to the Canadian province, wildfires are not. In British Columbia alone there are close to 500 wildfires active to date.

Caffeine helps quickly boost wakefulness following general anesthesia, a new study finds. The stimulant — used daily by more than 90 percent of adults in the U.S. — appears to alter physiological function in two different ways to shorten recovery time.

Molecules that help cells communicate with each other -- called cytokines -- might be the key to repairing diabetic nerve damage. Diabetes devastates nerve cells, which can lead to poor circulation, muscle weakness, blindness, and other painful side effects. The new study showed diabetic mice can't repair nerve cells after damage due to low levels of specific cytokines.

Strategies to improve our appetites as we age include reducing portion size, increasing meal frequency, and using flavor enhancers. Until recently, however, these options have not proven to improve food intake or quality of life for older people. That's part of the reason why a team of researchers designed a study to examine the differences in food intake among older adults with varied appetite levels.

Staphylococcus aureus (staph) is the leading cause of hospital-acquired infections. Antibiotic-resistant strains of the bug, like MRSA, can kill. If S. aureus is going to drink our blood like a vampire, let's kill it with sunlight, suggests new research.

A new generation of manganese dioxide-zinc batteries with unprecedented cycle life and energy density has now been revealed by scientists. The discovery has made the common household battery suitable for large grid storage applications.

Each cell in the body is made up of a number of tiny sealed membranous subunits called organelles, and they send things like lipids back and forth to allow the cell to function. A process called membrane tethering is responsible for bridging the gap between organelles, and now, researchers have discovered a way to manipulate this tethering.

Accurately determining the time since death is an important aspect of forensic sciences and casework.

Although most people don't broadcast in advance their intention to engage in criminal activity, scientists have discovered that the use of Twitter can help predict crime.

New statistical analysis examining changes in batter productivity as a result of the recently changed strike zone could raise concern for the Major League Baseball Players Union and individual baseball players.

What determines how kids decide to spend their cash on snacks? In a study with Boston-area children, researchers show that their experience with money and their liking of brands influenced decisions -- and that for some children, higher prices for unhealthy snacks might motivate healthier choices.

A new type of photoinitiator for 3-D printing in water could further the development of biomedical accessories, bring advances in traditional industries such as plastics, and offer an environmentally friendly approach to additive manufacturing.

Not much surprises the oilbird. Its senses are super sharp and when combined, may function in a way that can inspire researchers to construct better drones and more advanced technology.
