Now, self-healing materials can mimic human skin, healing again and again

...the researchers suggest. The improved design would allow new healing chemistries such as two-part epoxies to be exploited, which could ultimately lead to unlimited healing capability. Currently, the material can heal cracks in the epoxy coating analogous to small cuts in skin, Sottos said. The next step...

Researchers identify fifth gene responsible for Joubert syndrome

...y cilia are tiny projections on cell surfaces that allow the inside of cells to communicate with their outside environment. Recent research has found that defects in cilia function lead to various newly identified syndromes called ciliopathies. The paper describes a genetic change that prevents interaction...

Cancer stem cells can go it alone

... Having a model cancer stem cell system will also allow researchers to identify genes and proteins that will help with the search for human breast cancer stem cells in the future. As we learn more about tumor formation at the single cell level in tissue, we may be able to specifically target cancer stem c...

Scientists propose the kind of chemistry that led to life

...is that simple principles of chemical interactions allow for a kind of natural selection on a micro scale: enzymes can cooperate and compete with each other in simple ways, leading to arrangements that can become stable, or locked in, says Ken Dill, PhD, senior author of the paper and professor of pharmace...

New study finds genetically engineered crops could play a role in sustainable agriculture

UCLA researchers discover novel pathway that may promote immune system balance

... cells. This discovery offers a strategy that will allow for the design of drugs to modulate the immune system. Its a new way to look at drug design. Shuai and his colleagues discovered the PIAS1 anti-inflammatory pathway, a pathway commonly used by a wide variety of stimulants that regulate immune syst...

QUT microgravity tower attracts global scientific community

...ed later this year. The microgravity tower will allow scientists to study, in a reduced-gravity environment, many diverse phenomena in many fields including nanomaterials, new materials, fire-safety, metallurgy, biotechnology and combustion.

The new site includes up-to-date images on 12 intact but vulnerable villages as well as archival satellite phot...

Neuronal activity gives clues to working memory

...atory cells, and it is the inhibitory neurons that allow the two groups to interact. "In our experiments, we used pharmacologic means to interrupt either excitatory or inhibitory pathways, and then we watched what happened to persistent firing," Dr. Aksay says. When the excitatory pathways were dampened,...

Envisat captures first image of Sargassum from space

...at. The ability to monitor Sargassum globally will allow researchers to understand better the primary productivity of the ocean and better predict climate change. Using optical radiance data from the Medium Resolution Imaging Spectrometer (MERIS) aboard Envisat, Dr Jim Gower and Stephanie King of the Can...

"Although more than 400 scientific papers based on RB data have already been published, its a w...

UC Irvine awarded $3.9 million to upgrade stem cell research facilities, training

... honored to be chosen for this funding, which will allow us to enhance our already top-notch facility and popular training course, said Peter Donovan, co-director of the Sue and Bill Gross Stem Cell Research Center at UCI. Modern facilities and trained scientists are key to developing future stem cell ther...

A new plant-bacterial symbiotic mechanism promising for crop applications

...l requires the presence of several nod genes which allow synthesis of the Nod factor, a compound elaborated by the bacterium which enables the plant to recognize it, by molecular recognition, thereby allowing the microorganism to penetrate inside the plant by the root hairs. The finding raises the questio...
