Circulating bone-marrow derived cells do not contribute to egg formation

Ovulated egg cells, or oocytes, in adult female mice are not formed from germ cells in the blood or bone marrow.

Tandem-pore K+ channels mediate inhibition of orexin neurons by glucose

One of the body's basic survival mechanisms is the neural machinery that triggers the hungry brain to the alertness needed for seeking food.

Neurons can produce Alzheimer's-linked apolipoprotein E

A question long debated among Alzheimer's disease researchers has been definitively answered by scientists at the Gladstone Institute of Neurological Disease in San Francisco.

Stem cell 'fusion' occurs in tumors

An Oregon Health & Science University study is adding credence to an increasingly popular theory that fusion is what bonds stem cells with bone marrow cells to regenerate organ tissue.

New insight into the way an embryonic retina cell develops

The discovery provides a new vantage point for understanding how a healthy visual system develops. It also raises the possibility of re-directing the production of cell types as needed to stave off eye disease.

Effective gene suppression using small interfering RNA in hard-to-transfect human T cells

A technical advance in laboratory techniques may provide biology researchers broader access to RNA interference, a process of blocking the activity of targeted genes. RNA interference has recently emerged as an important tool in studying how genes function in normal biological processes and in disease.

Study provides a boost for efforts to reverse type-1 diabetes

Researchers have been able to confirm most but not all of the results of a high-profile study that brought new hope to diabetes patients. This study provides a boost for efforts to reverse type-1 diabetes in recently diagnosed patients but not for efforts to grow new islets from spleens.

Real-time molecule-by-molecule "movie" of protein production in live cells

Chemists at Harvard University have developed the first technique providing a real-time, molecule-by-molecule "movie" of protein production in live cells.

New genome-wide map of miRNA-MRNA interactions

Researchers at New York University's Center for Comparative Functional Genomics and the University of California, Berkeley have used computational analyses to predict a genome-wide map of microRNA (miRNA) targets in the animal model organism, Caenorhabditis elegans (C. elegans).

Cornell develops technique for making living, functional cells glow

The development gives researchers insights into how hearts develop in living mouse embryos and could improve our understanding of irregular heartbeats, known as arrhythmias, as well as open doors to observing cellular processes to better understand basic physiology and disease.

ATF2 protein may play a crucial role in cancer's ability to resist chemotherapy and radiation treatment

Researchers at Purdue University have discovered a molecular mechanism that may play a crucial role in cancer's ability to resist chemotherapy and radiation treatment and that also may be involved in Alzheimer's and heart disease.

New findings help researchers revise models of mammalian sense of smell

In a mouse model, University of Pennsylvania School of Medicine researchers discovered that olfactory sensory neurons expressing the same receptor responded to a specific odor with an array of speeds and sensitivities, a phenomenon previously not detected in the mammalian sense of smell.

Scientists have determined the detailed structure of an essential piece of the telomerase enzyme

Scientists have determined the detailed structure of an essential piece of the telomerase enzyme, an important contributor to the vast majority of human cancers. Understanding the physical shape of the protein has led to a better understanding of how it acts to immortalize cells - and should help scientists design broadly effective cancer drugs.

New research has implications for treating muscular dystrophy

In a surprising discovery with implications for treating muscular dystrophy, researchers at the University of Utah School of Medicine and other institutions have identified a major source of origin for two groups of adult cells that regulate muscle repair.

Bacterial DNA and IVF contamination risk on New Scientist

Some children conceived by a common method of IVF could be carrying chunks of bacterial DNA in their chromosomes, according to a study in mice. The researchers who conducted the work say that such accidental genetic modification would be very rare, but they argue that fertility doctors should take more precautions to exclude it.

Sperm stem cells research provides exciting findings

New experiments that prevented rat sperm stem cells from changing permanently into sperm have brought researchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body.
