Wisconsin scientists grow critical nerve cells

...wn the correct developmental pathway. "You need to teach the [embryonic stem cells] to change step by step, where each step has different conditions and a strict window of time," says Zhang. "Otherwise, it just won't work." To differentiate into a functional spinal motor neuron, the stem cells advanced th...

U-M scientist to talk about tissue engineering at AAAS

Scientists have a pretty good handle on how to teach human cells to do tricks in a laboratory---things like getting soft cells from the mouth's lining to form bone. But in the real world, accomplishing such feats is more complex. Regenerating the jaw bone of a person undergoing radiation therapy for c...

Jefferson Virologists Coax HIV Out of Hiding

... an unknown viral reservoir in the blood. “IL-7may teach us something,?he says. “We’re not sure why only thesecertain strains are affected. We think we’ve found a new population, anew reservoir of HIV that has not been seen before. It’s probably asub-population of blood cells, lymphocytes not stimulated by...

Birds brains reveal source of songs

...al ganglia circuit, so birds may have something to teach us about our own brains and what we learn may eventually apply to human diseases that affect motor abilities, such as Parkinson's disease. "The question we're trying to answer is how a young bird learns its song," says Professor Michale Fee of MIT's...

Mouse gene shows new mechanism behind cardiac infarction in man

...nbiased genetic strategy based on a mice model can teach us more about common human diseases,?says researcher Jacob Lagercrantz of the Gustav V research institute, Karolinska Institutet. The gene codes for a protein called OX40L, which is involved in the activation of immunological T cells. These cells, i...

UNC plant researchers discover proteins interact to form hair-trigger protection against invaders

...pecies. Understanding Arabidopsis completely will teach scientists an enormous amount about all other flowering plants, which are closely related genetically, Dangl said. The new genomics technology, developed by Patrick Brown and David Botstein at Stanford University, has been applied to yeast, fruit fli...

'Shifty-eyed' Monkeys Offer Window Into Brain's Social Reflexes

...better treatments for autism and better methods to teach autistic children. The researchers, post-doctoral fellow Robert Deaner and Assistant Professor Michael Platt, reported their findings in the Sept. 16, 2003, issue of Current Biology. The research was supported by the National Institute of Mental Hea...

Clear rules needed to govern deep sea bioprospecting: UNU

...ed and other ecological services, and have much to teach us about life processes," says UNU-IAS Director A.H. Zakri. "The unfettered and unregulated exploitation of international sea beds and the organisms living there could have serious long-term consequences for humankind," he says. "And for the private...

Scientists and engineers apply nature's design to human problems

..., CBID co-director. "In comparative physiology, we teach that every animal has to solve a particular problem to survive, so every animal is a design solution for a particular problem. "They can provide solutions for more efficient manufacturing and design of materials with new capabilities, for example. ...

Regenerating worms help elucidate stem cell biology

...cell biology. "I think they probably have a lot to teach us about how a population of stem cells is being regulated in vivo, rather than in a Petri dish," he said. So Sánchez Alvarado and his colleagues set out to understand exactly how neoblasts carry out the remarkable maintenance and recreation of ...

Web model of influenza-host lifecycles will aid scientists in creating anti-viral drugs

... part of a project called Reactome, is intended to teach scientists about parts of the influenza lifecycle they might not be familiar with, and to help researchers look at specific reactions and figure out ways to block them. "Understanding how influenza reacts with its host is really critical for the rat...

'Accelerated evolution' converts RNA enzyme to DNA enzyme in vitro

...ecules have interesting catalytic properties, they teach us something new about evolution, and they have potential application as therapeutic and diagnostic agents." ...

Bringing the zoos to the zebras

...firsthand, Earthwatch makes keepers better able to teach the zoo public about the ecological issues confronting Grevy's zebras. "Zoos have an important role in the future of biodiversity, and are a key stakeholder in Earthwatch's research and education programs," said Dr. Marie Studer, chief science offic...

NJIT engineer poised to take stem cell research a step forward

...the stem cell repair of cartilage. Rizio will also teach Arinzeh, and some of her students, how to insert stem cells in to patients' knees during surgery. Arinzeh's drive to advance the science of stem cell research has gained her national recognition. Two years ago, she earned the highest honor given to...

Penguins waddle but they don't fall down, UH researchers say

...aid. "This research may aid in developing a way to teach those people how to walk more efficiently despite their side-to-side motion, to learn the same kind of stability as the penguin." Another application for this research involves the construction of sophisticated robots. Kurz said it is very expens...

Gene variation increases SIDS risk in African Americans

...might screen to identify children at high risk and teach parents how to lessen the likelihood of secondary challenges. We have already begun to evaluate drugs that may mitigate the risk." SIDS -- the sudden and unanticipated death of an infant with no detectable lethal disorder -- is the leading cause of...

APS lecturer shows rare video of 'teacher-student' immune cell interactions in live animal

... cells -- professional antigen-presenting cells -- teach T cells to respond to an infection. "This had never been observed in a live system before we obtained it," von Andrian said of the footage "Before this, what had gone on inside the lymph node was largely a black box." His team published their first ...

With cochlear implants, earlier use leads to better speech

...now how to have a conversation in sign language or teach it to their children. Many of these parents would like their children to learn spoken language." The researchers tested the spoken language skills of 76 children, all 3 and a half years old, who had cochlear implants and compared those results to t...
