Key signaling molecule that helps stem cells make healthy bone declines as we age

With age, expression of a small molecule that can silence others goes way up while a key signaling molecule that helps stem cells make healthy bone goes down, scientists report.

Researchers identify key step in how plant cells respond to pathogens

Just like humans, plants have an immune system that helps them fight off infections. Plant immunity has some important differences: they don't make antibodies and can't fight off the same bug more quickly months or years later.

Researchers discover how plants harness microbes in soil to get nutrients

A Rutgers-led team has discovered how plants harness microbes in soil to get nutrients, a process that could be exploited to boost crop growth, fight weeds and slash the use of polluting fertilizers and herbicides.

New research on sperm quality updates advice for couples trying to conceive

Could doctors at fertility clinics be giving men bad advice? Dr. Da Li and Dr. XiuXia Wang, who are clinician-researchers at the Center for Reproductive Medicine of Shengjing Hospital in Shenyang in northeast China, think so.

Scientists discover novel mechanism by which synthesized proteins reach target compartment in cell

Proteins are essential constituents of cells and their compartments. Prof. Johannes Herrmann, a researcher at the Technische Universität Kaiserslautern, Germany, and his team discovered a novel mechanism by which newly synthesized proteins reach their respective target compartment in the cell.

New studies examine links between fatty liver disease and mitochondrial dysfunction

Researchers at Northeast Ohio Medical University studied the lifespan of mitochondrial proteins in a mouse model of fatty liver disease. Comparing the amount of protein between healthy mice and a mouse model of nonalcoholic fatty liver disease gave them an estimate of each protein's half-life.

Salk research in yeast leads to serendipitous finding about hypomyelinating leukodystrophy

Studying the fundamental aspects of biology can sometimes lead to unexpected findings that directly relate to human disease. In one of the latest examples of scientific serendipity, researchers from the Salk Institute found that an important quality control mechanism in baker's yeast is closely connected to hypomyelinating leukodystrophy, a debilitating disease found in children.

Replacement bisphenols cause reproductive defects in lab mice

Twenty years ago, researchers made the accidental discovery that the now infamous plastics ingredient known as bisphenol A or BPA had inadvertently leached out of plastic cages used to house female mice in the lab, causing a sudden increase in chromosomally abnormal eggs in the animals.

People display clear signs of confirmation bias when judging on sensory input

People have a tendency to interpret new information in a way that supports their pre-existing beliefs, a phenomenon known as confirmation bias.

Study could pave way for new therapies to reverse aging in human cells

Research has shed new light on genetic processes that may one day lead to the development of therapies that can slow, or even reverse, how our cells age.

Researchers describe mechanism that sets stage for fate decision of T cells

After a pathogen infects the body, the immune system responds with a remarkable -- and remarkably complicated -- cascade of events.

Blood serum induces spontaneous movement and growth of skin cells

What happens to skin cells when they are confronted with blood? A team of researchers from Oslo University Hospital, led by Emma Lång and Stig Ove Bøe, performed experiments on blood-deprived cells that were subsequently exposed to blood serum.

Aging may have originated at the very beginning of life, says study

A new USC Dornsife study indicates that aging may have originated at the very beginning of the evolution of life, at the same time as the evolution of the first genes.

Study provides complete picture of HPV virus-head and neck cancer connections

Human papillomavirus is widely known to cause nearly all cases of cervical cancer. However, you might not know that HPV also causes 70 percent of oropharyngeal cancer, a subset of head and neck cancers that affect the mouth, tongue, and tonsils.
