Distinct neurological syndromes can be the result of variations in gene ATAD3A Posted: 22 Oct 2016 01:19 PM PDT A team of scientists has discovered that rare neurological syndromes for which there was no cause can be the result of variations in the gene ATAD3A. The study sheds light on the causes of these diseases and opens the possibility for developing better diagnostic tools and potential treatments in the future.

New strategy to prevent Alzheimer's disease Posted: 22 Oct 2016 01:19 PM PDT Taking a pill that prevents the accumulation of toxic molecules in the brain might someday help prevent or delay Alzheimer's disease, according to scientists.

Measuring the forces of biology Posted: 21 Oct 2016 12:50 PM PDT Biology, at the nitty-gritty level of motor proteins, DNA, and microtubules, takes its cue from physics. But while much is known about the biological components that form such cellular stuctures, researchers are only beginning to explore the physical forces between those components.

Patients Weigh in on Orthopedic Surgeons' Pay, Reimbursement Posted: 20 Oct 2016 01:37 PM PDT Most patients don't think an orthopedic surgeon is overpaid but they greatly exaggerate how much a surgeon is reimbursed by Medicare for performing knee surgery, according to a study of patient perceptions.

Benefits of laser treatments for dental problems Posted: 20 Oct 2016 11:35 AM PDT Researchers have developed computer simulations showing how lasers attack oral bacterial colonies, suggesting that benefits of using lasers in oral debridement include killing bacteria and promoting better dental health.

Nanoparticle vaccinates mice against dengue fever Posted: 20 Oct 2016 11:31 AM PDT Every year, more than 350 million people in over 120 countries contact dengue fever, which can cause symptoms ranging from achy muscles and a skin rash to life-threatening hemorrhagic fever. Researchers have struggled to create effective vaccines against dengue virus, in part because four distinct serotypes, or strains, cause the disease and a vaccine must immunize against all four individually. Now, a new type of nanoparticle effectively vaccinated mice against one of the serotypes and could be created to target all four.

How human eggs end up with the wrong number of chromosomes Posted: 20 Oct 2016 11:29 AM PDT One day before ovulation, human oocytes begin to divide into what will become mature eggs. Ideally, eggs are packaged with a complete set of 23 chromosomes, but the process is prone to error, especially with age. In a new article, researchers discuss the latest research on why many human oocytes frequently have a wrong number of chromosomes--which may lead to genetic disorders, such as Down syndrome and miscarriage.

Rac1 protein critical for lung development Posted: 20 Oct 2016 10:56 AM PDT A promising therapeutic target has been discovered for improving lung function in infants. The study shows that a protein called Rac1 is critical for the proper development of mammalian lung.

Workplace weight management lowers costs, improves quality of life Posted: 20 Oct 2016 10:56 AM PDT Employees who participate in a workplace weight management program—even those without significant weight loss—have reduced health care costs and improved quality of life (QOL), reports a new study.

Mismatched cuisine could make your meal more enjoyable Posted: 20 Oct 2016 10:22 AM PDT Ordering an Italian main course? According to a food science researcher, if you want to be certain you'll enjoy your meal, you should probably get the spring rolls to start.

New research verifies TASINs as viable target for colon cancer therapies Posted: 20 Oct 2016 10:19 AM PDT A small molecule called TASIN-1 can selectively kill cells with a mutation that is considered to be a precursor to colon cancer, while sparing related normal cells, cancer biologists have demonstrated.

Zika virus infection alters human, viral RNA Posted: 20 Oct 2016 09:08 AM PDT Zika virus infection leads to modifications of both viral and human genetic material, scientists have discovered. These modifications — chemical tags known as methyl groups — influence viral replication and the human immune response.
