Personalized approach enhances communication skills in children with autism

Personalized approach enhances communication skills in children with autism

A UCLA-led study has found that the communication skills of minimally verbal children with autism can be greatly improved through personalized interventions that are combined with the use of computer tablets. Continue reading

Tooth plaque provides unique insights into our prehistoric ancestors’ diet

Tooth plaque provides unique insights into our prehistoric ancestors’ diet

An international team of researchers has found new evidence that our prehistoric ancestors had a detailed understanding of plants long before the development of agriculture. By extracting chemical compounds and microfossils from dental calculus (calcified dental plaque) from ancient teeth, the researchers were able to provide an entirely new perspective on our ancestors’ diets.

Mormon pioneer mortality rate calculated at 3.5 percent

Mormon pioneer mortality rate calculated at 3.5 percent

The final stanza of the Mormon pioneer anthem “Come, Come Ye Saints” directly confronts the prospect of dying on the trail: “And should we die, before our journey’s through…” Now new research shows that pioneer mortality rates were not much greater than national averages at the time. This may come as a surprise to modern Mormon youth who’ve participated in handcart treks Continue reading

‘Mississippi Baby’ now has detectable HIV, researchers find

The child known as the “Mississippi baby” — an infant seemingly cured of HIV that was reported as a case study of a prolonged remission of HIV infection in The New England Journal of Medicine last fall — now has detectable levels of HIV after more than two years of not taking antiretroviral therapy without evidence of virus, according to the pediatric HIV specialist and researchers involved in the case. “Certainly, this is a disappointing turn of events for this young child, the medical staff involved in the child’s care, and the HIV/AIDS research community,” said NIAID Director Anthony S Continue reading

Huntington’s disease protein helps wire young brain

Huntington’s disease protein helps wire young brain

The protein that is mutated in Huntington’s disease is critical for wiring the brain in early life, according to a new Duke University study. Huntington’s disease is a progressive neurodegenerative disorder that causes a wide variety of symptoms, such as uncontrolled movements, inability to focus or remember, depression and aggression. By the time these symptoms appear, usually in middle age, the disease has already ravaged the brain. Continue reading

Time of day crucial to accurately test for diseases, new research finds

Time of day crucial to accurately test for diseases, new research finds

A new study published in the journal PNAS (Proceedings of the National Academy of Sciences) , has found that time of day and sleep deprivation have a significant effect on our metabolism. The finding could be crucial when looking at the best time of day to test for diseases such as cancer and heart disease, and for administering medicines effectively Continue reading

New discovery in living cell signaling

New discovery in living cell signaling

A breakthrough discovery into how living cells process and respond to chemical information could help advance the development of treatments for a large number of cancers and other cellular disorders that have been resistant to therapy. An international collaboration of researchers, led by scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley, have unlocked the secret behind the activation of the Ras family of proteins, one of the most important components of cellular signaling networks in biology and major drivers of cancers that are among the most difficult to treat Continue reading

Leading hypothesis for miscarriages, birth defects ruled out

Leading hypothesis for miscarriages, birth defects ruled out

Washington State University reproductive biologists have ruled out one of the leading thoughts on why older women have an increased risk of miscarriages and children with birth defects. The 46-year-old “production-line hypothesis” says that the first eggs produced in a female’s fetal stage tend to have better connections or “crossovers” between chromosomes Continue reading
