Human-derived stem cells can spontaneously form optic cups and retina

Human-derived stem cells can spontaneously form the tissue that develops into the part of the eye that allows us to see, according to a study published by Cell Press in the 5th anniversary issue of the journal Cell Stem Cell.

RNA-binding proteins accumulate in the brains of patients with AD

Researchers from Boston University School of Medicine (BUSM) have identified a novel group of proteins that accumulate in the brains of patients with Alzheimer's disease. These findings, which appear online in the Journal of Neuroscience, may open up novel approaches to diagnose and stage the progression likelihood of the disease in Alzheimer patients.

Novo Nordisk, JDRF partner to discover and develop novel immunotherapies against T1D

To address the underlying autoimmune process that is central to type 1 diabetes (T1D), JDRF and Novo Nordisk are partnering to discover and develop novel immunotherapies to prevent, treat, and help cure the disease.

Fluidigm unveils details of new C1 Single-Cell AutoPrep System at ISSCR meeting

Fluidigm today unveiled the details of its new C1 Single-Cell AutoPrep System to attendees at the International Society for Stem Cell Research (ISSCR) meeting in Yokohama, Japan.

New microfluidic device can sort cancer cells, particles

In life, we sort soiled laundry from clean; ripe fruit from rotten. Two Johns Hopkins engineers say they have found an easy way to use gravity or simple forces to similarly sort microscopic particles and bits of biological matter -- including circulating tumor cells.

New study on motor chunking

You pick up your cell phone and dial the new number of a friend. Ten numbers. One. Number. At. A. Time. Because you haven't actually typed the number before, your brain handles each button press separately, as a sequence of distinct movements.

Scientists decipher and block a molecular message that prompts unbridled cellular growth

What's good news in one setting might spell disaster in another. In cancer for instance, when a certain cell is commanded to grow and divide without restraint, it's a welcome message for the cell itself but a tragedy for the person who harbors this cell in his or her body. Weizmann Institute scientists have managed to decipher and block one type of molecular message that prompts unbridled cellular growth.

Researchers identify prognostic marker in chronic lymphocytic leukemia

Researchers have identified a prognostic marker in the most common form of chronic leukemia that can help to distinguish which patients should start treatment quickly from those who can safely delay treatment, perhaps for years.

Long-lasting weekly fertility injections work as well as daily

New long-lasting weekly injections of fertility hormones are as safe and effective as standard daily injections, according to Cochrane researchers. The researchers compared weekly and daily hormone injections in a Cochrane systematic review and found no difference in pregnancies or serious side effects between the two regimens.

HLA B-27 protein appears to confer ability to suppress HIV viral replication

The rare ability of some individuals to control HIV infection with their immune system alone appears to depend - at least partially - on specific qualities of the immune system's killer T cells and not on how many of those cells are produced.

Caspase-11 enzyme plays an important role in Legionella infection

New research shows that an enzyme that has long been considered relatively useless to the immune response instead has an important role in setting up immune cells to kill infection-causing bacteria.

New tool should serve as cellular equivalent for children with CDG syndromes

Just as Gotham City uses the Bat Signal to call for Batman's aid, a new tool developed by scientists from the Sanford-Burnham Medical Research Institute in La Jolla, California, should serve as the cellular equivalent for children with glycosylation disorders, sometimes called "CDG syndromes."

Acute and chronic elevation of EPO in the brain improve motivation for exercise

As science rushes to develop safe weight loss drugs, a new research report approaches this problem from an entirely new angle: What if there were a pill that would make you want to exercise harder? It may sound strange, but a new research report appearing online in The FASEB Journal suggests that it might be possible.

Transgenic mosquitoes can control malaria

Mosquitoes bred to be unable to infect people with the malaria parasite are an attractive approach to helping curb one of the world's most pressing public health issues, according to UC Irvine scientists.

Genetic variability in the embryo may predispose to cancer in adult life

A study recently published in Nature Genetics provides new evidence that the genetic makeup of the embryo may cause the appearance of tumors in adult life. These results bear out the growing theory that some tumors may have an extremely early origin, tracing to the individual's embryonic development, while offering new clues to understand the genetic causes of certain kinds of cancer, and their prevention and treatment.

Billions of specific gut bacteria may play a role in autoimmune diseases

The billions of bugs in our guts have a newfound role: regulating the immune system and related autoimmune diseases such as rheumatoid arthritis, according to researchers at Mayo Clinic and the University of Illinois at Urbana-Champaign.

14-3-3 zeta protein involved in generating chronic pain

Researchers in France and Sweden have discovered how one of the body's own proteins is involved in generating chronic pain in rats. The results, which also suggest therapeutic interventions to alleviate long-lasting pain, are reported in The EMBO Journal.

Gut microbes regulate brain levels of serotonin

UCC scientists have shown that brain levels of serotonin, the 'happy hormone' are regulated by the amount of bacteria in the gut during early life. Their research is being published today in the leading international psychiatry journal, Molecular Psychiatry.

Experimental drug and genetic differences indicate how people deal with fear and stress

Researchers at Duke University and the National Institutes of Health have found a way to calm the fears of anxious mice with a drug that alters their brain chemistry. They've also found that human genetic differences related to the same brain chemistry influence how well people cope with fear and stress.

Hepatocytes can create new liver system in mouse models

Researchers in Japan have found that hepatocytes, cells comprising the main tissue of the liver and involved in protein synthesis and storage, can assist in tissue engineering and create a "new liver system" in mouse models when donor mouse liver hepatocytes are isolated and propagated for transplantation.
