When we forget to remember: Failures in prospective memory range from annoying to lethal Posted: 31 Jul 2012 12:17 PM PDT Why would highly skilled professionals forget to perform a simple task they have executed without difficulty thousands of times before? These kinds of oversights occur in professions as diverse as aviation and computer programming, but research reveals that these lapses may not reflect carelessness or lack of skill but failures of prospective memory.

Eyes and attention of men and women meander in distinctly different ways Posted: 31 Jul 2012 12:17 PM PDT Researchers show that the eyes and attention of men and women meander in distinctly different ways. Men park their eyes on the speaker's mouth. Women shift their focus between the speakers eyes and body.

Concussions and head impacts may accelerate brain aging Posted: 31 Jul 2012 12:17 PM PDT Concussions and even lesser head impacts may speed up the brain's natural aging process by causing signaling pathways in the brain to break down more quickly than they would in someone who has never suffered a brain injury or concussion.

Study of zebra fish mouth formation may speak to Fraser syndrome hearing loss Posted: 31 Jul 2012 10:50 AM PDT Using mutant zebra fish, researchers studying the earliest formation of cartilage of the mouth believe they may have gotten a look at a mechanism involved in a genetic defect linked to Fraser syndrome deafness in humans.

Childhood obesity may affect timing of puberty, create problems with reproduction Posted: 31 Jul 2012 10:50 AM PDT A dramatic increase in childhood obesity in recent decades may have impacts that go beyond the usual health concerns – it could be disrupting the timing of puberty and ultimately lead to a diminished ability to reproduce, especially in females. A body of research suggests that obesity could be related to growing problems with infertility.

From microns to centimeters: Researchers invent new tissue engineering tool Posted: 31 Jul 2012 10:50 AM PDT Imagine a machine that makes layered, substantial patches of engineered tissue -- tissue that could be used as grafts for burn victims or vascular patches. Sounds like science fiction? According to engineers, it's a growing possibility. Scientists have invented a new device that may allow for the uniform, large-scale engineering of tissue.

Immune responses can be generated locally within human melanoma skin metastases Posted: 31 Jul 2012 10:48 AM PDT In many types of cancer, activated immune cells infiltrate the tumor and influence clinical outcome. It is not always clear where these cells are activated, but new results indicate that in a subset of patients with metastatic melanoma, they can be activated in the tumor micro-environment.

Protein-based coating could help rehabilitate long-term brain function Posted: 31 Jul 2012 09:35 AM PDT Scientists have developed a bioactive coating which not only "camouflages" electrodes in the brain tissue but also suppresses the brain's immune response. With this method, researchers hope to turn the short-term effects of deep brain stimulation into a long-term solution.

Computational analysis identifies drugs to treat drug-resistant breast cancer Posted: 31 Jul 2012 09:33 AM PDT Researchers have used computational analysis to identify a new Achilles heel for the treatment of drug-resistant breast cancer. The results reveal that the disruption of glucose metabolism is an effective therapeutic strategy for the treatment of tumors that have acquired resistance to front-line cancer drugs such as Lapatinib.

New anesthesia drugs developed to be 'fast, clean, and soft' Posted: 31 Jul 2012 09:32 AM PDT Researchers are using sophisticated and powerful new tools to develop and evaluate new anesthetic agents with important advantages over current drugs, according to a several new articles.

Dementia: Autoantibodies damage blood vessels in the brain Posted: 31 Jul 2012 08:14 AM PDT The presence of specific autoantibodies of the immune system is associated with blood vessel damage in the brain. New results suggest that autoimmune mechanisms play a significant role in the pathogenesis and progression of Alzheimer's and vascular dementia.

Opioid receptors as a drug target for stopping obesity Posted: 31 Jul 2012 07:30 AM PDT Imagine eating all of the sugar and fat that you want without gaining a pound. Thanks to new research the day may come when this is not too far from reality.

Stress during pregnancy leads to abdominal obesity in mice offspring Posted: 31 Jul 2012 07:30 AM PDT A new report involving mice suggests that a relationship exists between maternal metabolic or psychological stress and the development of obesity, type 2 diabetes, and metabolic syndrome in her offspring.

Sick from stress? Blame your mom… and epigenetics Posted: 31 Jul 2012 07:30 AM PDT If you're sick from stress, a new research report suggests that what your mother ate -- or didn't eat -- may be part of the cause.

Allergies? Your sneeze is a biological response to the nose's 'blue screen of death' Posted: 31 Jul 2012 07:30 AM PDT Who would have thought that our noses and Microsoft Windows' infamous blue screen of death could have something in common? New research suggests that sneezing is the body's natural reboot and that patients with disorders of the nose such as sinusitis can't reboot, explaining why they sneeze more often than others.

'Flightless' molecule may prevent cancer from spreading from one tissue to another Posted: 31 Jul 2012 07:30 AM PDT Thanks to the "flightless" molecule, the spread of cancer from one tissue to another may one day be grounded. Laboratory experiments show that "flightless" (named after its effects on fruit flies) increases the "stickiness" that causes cells, including cancer cells, to attach to underlying tissue, which in turn, slows their movement throughout the body.
