Lost in the labyrinth

...be a decision-maker, a selector of how information gets routed within the cell, rather than something which maintains the vitality of existing cells. Nerlov compares the breakdown to people standing at a fork in a labyrinth, hesitating before they go on. "We know there are strong connections to cells' d...

Gene linked with mental illness shapes brain region, researchers find

Male contraception: One door opens, another closes

...Contraception Information Project, says the public gets frustrated because media reports make it sound as ...us new research in the lab, but abandon it when it gets to the expensive part: actually testing it in men and getting it to market." This problem of movi...

German researchers develop first non-invasive test to measure skin aging

... of the dermis, the white lower-layer of skin that gets exposed in deep abrasions. Large variations appeared from patient to patient, and even from one part of a patient's forearm to another. "In a healthy 35-year-old, some areas can appear like the skin of a 25-year-old, and others like that of someon...

Stem cells engage in dialogue with the cells that regulate their futures

...dy. For example, if cell multiplication in a niche gets out of hand, cancer might form. A decline in cell production might contribute to the frailty of old age. While a few stem-cell niches have been known for a long time, what's been harder to discover are the characteristics of the cells making up t...

Nobel Laureate finds 'elegant' explanation for DNA transcribing enzyme's high fidelity

...ved, this is perhaps the most fundamental since it gets at the underlying mechanisms,?Kornberg said. “It’s long known that the enzyme operates with high fidelity—selecting the correct base and sugar—but it’s been a mystery how that is accomplished.? These findings offer “an unexpected and elegant explana...

Scientists crack rhino horn riddle

...es some of the mystique by explaining how the horn gets its distinctive curve and sharply pointed tip. Scientists have discovered new details about the structural materials that form the horn and the role those materials play in the development of the horn's characteristic shape. The horns of most a...

Why don't all moles progress to melanoma?

...ng goes wrong with the folding process, the system gets bogged down. This can stress or even kill the cell...PR). This slows the protein production process and gets rid of excess incoming amino acids, giving the ER a chance to catch up. If that doesn't work, the UP...

Key to zebrafish heart regeneration uncovered

...ur zebrafish model, we found that the regeneration gets to a certain point and then stops," Poss said. "The new blood vessels show poor invasion of the newly regenerating cells, halting the formation of new heart muscle." Poss said that a continued understanding of the processes involved in regeneratio...

How fish mend a broken heart

... chambers that make up the fish heart. "This study gets at some of the important mechanistic questions about how they rebuild the heart, and some of the key factors that contribute." In contrast to zebrafish, the cardiac damage and scarring caused by heart attacks is a major killer among humans, making ...

Researchers show that veins stiffen as we age

... blood vessels is a major factor in how much blood gets returned to your heart during the vital fluid's journey through your circulatory system. Every minute, the steady beating of that amazing living pump--your heart--sends about five quarts of blood through the 60,000-mile network of arteries, capilla...

Molecular motors and brakes work together in cells

...oblem is that the cargo -- the molecular brakes -- gets longer, slowing down the daughter train. But when the train gets to the end of the track it remains attached to the end of mother microtubule. At the tail end, it st...

Fungal factories may save hemlock forests

Whey is a far cheaper growing medium than those available in labs for the many fungi now in use as biological controls...

Fish can determine their social rank by observation alone, study finds

...essive fights, the outcome of which determines who gets access to food and mates. "Males that repeatedly lose fights are unable to hold territories and consequently descend in social status," the authors wrote. "Success in aggressive bouts is therefore crucial to male reproductive fitness, and the abi...

'Terror bird' arrived in North America before land bridge, study finds

... technique is timely and important. "If a fossil gets moved or reworked from its place of formation, it will have a fingerprint that is different from the others nearby," Grandstaff said. "Who knew that all these fossils essentially have a tag that says 'hey, I'm from over here!' " ...

Morphine makes lasting -- and surprising -- change in the brain

... release of dopamine, the "pleasure chemical" that gets released by naturally rewarding experiences. Drugs of abuse, from alcohol to cocaine, also increase dopamine release. So the net effect of morphine and other opioids, Kauer found, is that they boost the brain’s reward response. "It’s as if a brake...

Motor protein plays key role in connecting neurons

...an impair brain wiring or connectivity. "Myosin X gets the DCC receptor where it needs to be so it can interact with netrin-1." Her previous studies, published in 2004 in Nature Neuroscience, showed that DCC binding to netrin-1, activates an enzyme, focal adhesion kinase, enabling developing cells to ...

Deep in the ocean, a clam that acts like a plant

The actual work of photosynthesis in green plants is done by chloroplasts, descended from primitive single-celled organisms ...
