St. Jude study solves mystery of mammalian ears

...amplify the sound. An opposing group of scientists maintains that although the vibration of the outer hair cell body itself—somatic motility—does maximize the vibration of the cilia, the cell body works independently of its cilia. That is, vibration of the mammalian cell dominates the work of amplifying sound ...

Master regulatory gene of epithelial stem cells identified

...as been controversial. Some studies found that p63 maintains a steady pool of the regenerative cells, while other studies argued that p63 has more to do with causing the cells to differentiate into particular types of tissue. The study, which was lead by Frank McKeon, PhD, professor of cell biology at Harvard ...

Scientists develope a new model of artificial canine skin

MIT device draws cells close -- but not too close -- together

...ells on the edges of the combs to touch, the other maintains a gap of 80 micrometers, or about four cell widths. The assembly is geared so that switching between these two settings involves a movement of two millimeters, an amount controllable by the human hand. Hui selected 80 micrometers as the gap setting b...

Something new under the sun

... Van Ooteghem has developed a control system that maintains the correct climate in the greenhouse, whatever the weather outside. Different climate factors in the greenhouse, such as temperature and relative humidity, can be measured. Subsequently the correct adjustments to the settings of the greenhouse are m...

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

...n active niche, and in turn, the niche induces and maintains the fate of the stem cells," Ruohola-Baker noted. "This is a first indication of a dialogue taking place between the stem cells and the niche that supports them. It is tempting to speculate that maybe multiple potential niches exist for stem cells in...

Lost in the labyrinth

...outed 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' decisions to divide, to develop or to die. If cells don't commi...

Edible coatings will be the packaging of the future

...sult is a compound film that is resistant and that maintains suitable mechanical properties. The use of mesquite gum is an economical and efficacious alternative with a promising future, not only for food conservation, but it could also become an economic resource for indigenous peoples, currently marginalized...

Biofuel cells without the bio cells

...ge excess energy generated during metabolism. This maintains energy flow in the cell and, in turn, keeps the cell alive. The process has worked a little like that slogan for a hyper-electrified desert gambling town: What happens in the cellular environs stays there. Now, scientists for the first time have ...

Renewed dolphin slaughter prompts new campaign

...t control. Also, the "Act for Dolphins" consortium maintains that, in spite of the fact that the hunting of dolphins and use of their meat has waned in popularity, the government is actually encouraging the public to consume more dolphin meat; in addition to human consumption, dolphin meat is also used as pet ...

How the US drug safety system should be changed

...before the condition is removed." Secondly, Strom maintains that the FDA needs an increased ability to regulate drugs after marketing, so that it can require post-marketing studies and labeling changes as a rule, rather than those changes being subject to negotiation between the regulatory agency and industry...

Drug dials down the energy within cells, UM researchers find

... able to dial enzyme activity down to a level that maintains normal function while simultaneously allowing for initiation of a process that selectively kills or disables disease-causing cells." Glick and collaborators published their findings in the June 16 issue of ACS Chemical Biology. The drug, discovered...

Unusual mechanism keeps repair protein accurate

...ading regions or accessory molecules, this protein maintains its accuracy using an otherwise ordinary-looking portion of its molecular structure. The study was led by Zucai Suo, assistant professor of biochemistry and a researcher with the Ohio State University Comprehensive Cancer Center ?Arthur G. James C...

Tiny shock absorbers help bacteria stick around inside the body

...epartment of Materials at ETH Zurich. This process maintains an optimal force required to keep the finger trap-like FimH anchor from breaking loose. "This system is similar to a set of shock absorbers on your car that dampen turbulent forces caused by bumpy road conditions," added study co-author Dr. Wendy Th...

Tramiprosate (Alzhemed? preclinical results published in Neurobiology of Aging

Tramiprosate (Alzhemed? decreases by 38% (p-value Tramiprosate (Alzhemed? treatment in a transgenic mouse model of brain amyloidosis resulted in a dose-dependent reduction of over 60% of Aβ levels in plasma. There were ...

Sociality of sweat bees evolved simultaneously during climate change

"Other social insects (such as ants, termites, paper wasps and honey bees) have reached 'a point of no return' i...

Why nerve cells work faster than the theory allows

...als and suppress slow signals. Every living cell maintains a voltage difference across its cell membrane. Nerve cells distinguish themselves from other cells in that they use this voltage difference to process and transmit messages. When a nerve cell receives an impulse, the voltage across the cell membrane ...

MIT: Oceans are a major gene swap-meet for plankton

The collective Prochlorococcus community merely adjusts internally, with different groups (genome types) waxing and waning in relative abundance, depending on who is most fit under ever-changing...

Researchers reverse juvenile diabetes in animal model

A salty tale: New bacterial genome sequenced from ancient salterns

...rane and out of the cell. In doing so, the protein maintains a balance of ions inside and outside the cell. "It's very unusual to find the two different types of rhodopsin in the same organism," Mongodin says. "S. ruber may have independently evolved one type of rhodopsin and acquired the other through later...
