New Way to Generate Insulin-producing Cells in Diabetes

July 31, 2014 3:20 pm | Comments

A new study has found that a peptide called caerulein can convert existing cells in the pancreas into those cells destroyed in type 1 diabetes-insulin-producing beta cells.

Memory Relies on Astrocytes

July 29, 2014 11:46 am | Comments

When you're expecting something— like the meal you've ordered at a restaurant— or when or when something captures your interest, unique electrical rhythms called gamma oscillations sweep through your brain. New research shows that little known supportive cells in the brain known as astrocytes may in fact be major players that control these waves.

Unbreak My Heart

July 23, 2014 10:15 am | Comments

Researchers of the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden report how they managed to capture detailed three-dimensional images of cardiac dynamics in zebrafish. The novel approach: They combine high-speed Selective Plane Illumination Microscopy (SPIM) and clever image processing to reconstruct multi-view movie stacks of the beating heart.

Researchers Successfully Eliminate the HIV Virus from Cultured Human Cells

July 22, 2014 1:49 pm | Comments

The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of Temple University School of Medicine researchers has designed a way to snip out the integrated HIV-1 genes for good.

New Trigger for Ovulation Could Make IVF Safer

July 21, 2014 12:34 pm | Comments

Researchers have successfully used a new and potentially safer method to stimulate ovulation in women undergoing IVF treatment. Twelve babies have been born after their mothers were given an injection of the natural hormone kisspeptin to make their eggs mature.

New Gene Discovered that Stops the Spread of Deadly Cancer

July 18, 2014 2:01 pm | Comments

Scientists at the Salk Institute have identified a gene responsible for stopping the movement of cancer from the lungs to other parts of the body, indicating a new way to fight one of the world's deadliest cancers. By identifying the cause of this metastasis—which often happens quickly in lung cancer and results in a bleak survival rate—Salk scientists are able to explain why some tumors are more prone to spreading than others.

Cell Membrane Proteins Give Up Their Secrets

July 17, 2014 11:21 am | Comments

Rice University scientists have succeeded in analyzing transmembrane protein folding in the same way they study the proteins’ free-floating, globular cousins. Rice theoretical biologist Peter Wolynes and his team at the university’s Center for Theoretical Biological Physics (CTBP) have applied his energy landscape theory to proteins that are hard to view because they live and work primarily inside cell membranes.

One Injection Stops Diabetes in Its Tracks

July 17, 2014 11:03 am | Comments

In mice with diet-induced diabetes, the equivalent of type 2 diabetes in humans, a single injection of the protein FGF1 is enough to restore blood sugar levels to a healthy range for more than two days, according to a new study.

Climate Change May Bring More Kidney Stones

July 11, 2014 1:57 pm | Comments

As daily temperatures increase, so does the number of patients seeking treatment for kidney stones. In a study that may both reflect and foretell a warming planet’s impact on human health, a research team found a link between hot days and kidney stones in 60,000 patients in several U.S. cities with varying climates.

Dodging Dots Helps Explain Brain Circuitry

July 8, 2014 2:02 pm | Comments

A neuroscience study provides new insight into the primal brain circuits involved in collision avoidance, and perhaps a more general model of how neurons can participate in networks to process information and act on it. In the study, neuroscientists tracked the cell-by-cell progress of neural signals from the eyes through the brains of tadpoles as they saw and reacted to stimuli including an apparently approaching black circle.

Treasure Trove of Genes Key to Kidney Cancer

July 2, 2014 9:24 am | Comments

A genomic analysis of clear cell renal cell carcinoma (ccRCC), the most common form of kidney cancer, from 72 patients has uncovered 31 genes that are key to development, growth and spread of the cancer, according to researchers.
