New understanding for autism through eye tracking
New research has uncovered compelling evidence that genetics plays a major role in how children look at the world and whether they have a preference for gazing at people’s eyes and faces or at objects. The discovery by researchers at Washington University School of Medicine in St. Louis and Emory University School of Medicine in Atlanta adds new detail to understanding the causes of autism…

Plodding toward a pancreatic cancer screening test
Pancreatic cancer is one of the most deadly types of malignancies, with a 5-year survival rate after late diagnosis of only about 5%. The majority of patients—about 80%—receive their diagnosis too late for surgery. The disease spreads quickly and resists chemotherapy. In short, there is an urgent need for diagnostic tools to identify this cancer in its earliest stages.

When the internal clock is out of order
Persons suffering from schizophrenia have a different perception of time than healthy individuals, a new study finds. There is far more variation in the way that a time interval is perceived by people with schizophrenic disorders than by those who do not have the condition. Patients with schizophrenia are also less precise when it comes to judging the temporal order of events.

How treating dogs might help human cancer patients
The UC Davis Comparative Oncology Program joins oncologists at both the vet school and cancer center to test novel treatments on companion dogs with spontaneous tumors that could be effective in human patients with cancer. Human clinical trials could be started this year.

The key to depression may lie in our genes
Researchers have taken an in-depth look at the function of a gene that may be linked to the development of major depression. Their findings show that its activity levels might determine our susceptibility to stress and negative stimuli.

Discarded kindeys could save thousands of lives
The results of a new study suggest that high discard rates among donated kidneys could be avoided in the future. Researchers say that even kidneys with poor biopsy results may be more efficient in prolonging patients' lifespans than other treatments.
Drug for Parkinson's not likely to cause melanoma
People with the movement disorder Parkinson’s disease have a much higher risk of the skin cancer melanoma, and vice versa, a Mayo Clinic study finds. Yet the results of the study argue against the Parkinson's drug levodopa as the cause.

Computer model simulates sense of touch from the entire hand
Neuroscientists from the University of Chicago have developed a computer model that can simulate the response of nerves in the hand to any pattern of touch stimulation on the skin. The tool reconstructs the response of more than 12,500 nerve fibers with millisecond precision, taking into account the mechanics of the skin as it presses up against and moves across objects.

Why social isolation can bring a greater risk of illness
Social isolation has been linked to a wide range of health problems, as well as a shorter lifespan in humans and other animals.

Cancer cells may streamline their genomes to proliferate more easily
Research from the Stowers Institute provides evidence suggesting that cancer cells might streamline their genomes in order to proliferate more easily. The study, conducted in both human and mouse cells, shows that cancer genomes lose copies of repetitive sequences known as ribosomal DNA. While downsizing might enable these cells to replicate faster, it also seems to render them less able to…
