Interplanetary dust particles could deliver water and organics to jump-start life on Earth

Posted: 24 Jan 2014 01:12 PM PST

Researchers have discovered that interplanetary dust particles could deliver water and organics to the Earth and other terrestrial planets. "It is a thrilling possibility that this influx of dust has acted as a continuous rainfall of little reaction vessels containing both the water and organics needed for the eventual origin of life on Earth and possibly Mars," said Hope Ishii, study co-author.

Impulsive personality linked to food addiction

The same kinds of impulsive behavior that lead some people to abuse alcohol and other drugs may also be an important contributor to an unhealthy relationship with food, according to new research.

New study changes conceptions about the determinants of skull development and form

A new study offers surprising insights into dietary influences on the growing skull.

Psychologists document the age our earliest memories fade

Posted: 24 Jan 2014 10:57 AM PST

Although infants use their memories to learn new information, few adults can remember events in their lives that happened prior to the age of three. Psychologists have now documented that age seven is when these earliest memories tend to fade into oblivion, a phenomenon known as "childhood amnesia." The study is the first empirical demonstration of the onset of childhood amnesia, and involved interviewing children about past events in their lives.

Study expands cancer genomics universe

Posted: 24 Jan 2014 08:57 AM PST

By analyzing the genomes of thousands of patients' tumors, a research team has discovered many new cancer genes -- expanding the list of known genes tied to these cancers by 25 percent. The team's work, which lays a critical foundation for future cancer drug development, also shows that creating a comprehensive catalog of cancer genes for scores of cancer types is feasible with as few as 100,000 patient samples.

Do doctors spend too much time looking at computer screen?

When physicians spend too much time looking at the computer screen in the exam room, nonverbal cues may get overlooked and affect doctors' ability to pay attention and communicate with patients, according to a study.

Aspirin intake may stop growth of tumors that cause hearing loss

Posted: 24 Jan 2014 08:07 AM PST

Researchers have demonstrated, for the first time, that Aspirin intake correlates with halted growth of vestibular schwannomas (also known as acoustic neuromas), a sometimes lethal intracranial tumor that typically causes hearing loss and tinnitus.

Simple amoeba holds the key to better treatment for Alzheimer's disease

Households on inadequate incomes increases by a fifth. New research shows the number of households living on an inadequate income has increased by a fifth (900,000) in three years.

New cause identified for children, adults with joint, skeletal, skin problems

Posted: 24 Jan 2014 05:26 AM PST

Scientists have identified the cause of a rare condition called Leri's pleonosteosis (LP). LP is an inherited condition in which children are born with contractures of multiple joints and then develop difficulty of joint movements that progress in severity with age. The research team showed that extra genetic material on chromosome number 8 caused the condition in two families from Manchester.

The shape of infectious prions

Posted: 24 Jan 2014 05:26 AM PST

Prions are unique infective agents -- unlike viruses, bacteria, fungi and other parasites, prions do not contain either DNA or RNA. Despite their seemingly simple structure, they can propagate their pathological effects like wildfire, by "infecting" normal proteins. PrPSc (the pathological form of the prion protein) can induce normal prion proteins (PrPC) to acquire the wrong conformation and convert into further disease-causing agents.

Research shows gap in care for childhood cancer survivors

A recent study shows that many internists feel ill-equipped to care for adult patients who are childhood cancer survivors.

Sports medicine physical of future could help athletes 'ESCAPE' sudden cardiac death

Posted: 23 Jan 2014 12:48 PM PST

A young athlete in seemingly excellent health dies suddenly from a previously undetected cardiovascular condition such as hypertrophic cardiomyopathy in nearly every US state annually. Although these conditions can be detected using electrocardiography (ECG) during a screening exam, the American Heart Association recommends against routine use of ECG, because it has a high false-positive rate.
