Salk scientists untangle steroid hormone signaling in plants

...ent of plants' response to light, enabling them to adjust growth to reach light or strengthen stems. Exploiting its potent growth-promoting properties could increase crop yields or enable growers to make plants more resistant to drought, pathogens, and cold weather. Unfortunately, synthesizing brassinoste...

No-mow grass may be coming to your yard soon

...feedback loop has served plants well, helping them adjust their height and size to fit the growing conditions of any environmental niche. Through traditional methods of plant breeding, humans have been manipulating plant stature for thousands of years. In recent years, through the methods of genetic engin...

Brain-computer link lets paralyzed patients convert thoughts into actions

...only his thoughts. He could change the channel and adjust the volume on a television, even while conversing. He was ultimately able to open and close the fingers of a prosthetic hand and use a robotic limb to grasp and move objects. Despite a decline in neural signals after 6.5 months, Nagle remained an act...

Time of day tempers tadpoles' response to predators

... else's dinner. Scientists have known that prey adjust their activity levels in response to predation risk, but new research by a University of Michigan graduate student shows that internal factors, such as biorhythms, temper their responses. Michael Fraker, a doctoral student in the laboratory of ecol...

New GI technologies improve internal organ visualization

...sure patient response throughout the procedure and adjust the sedation dosage accordingly. Patient responsiveness was monitored by the anesthesiologist using the Modified Observer's Assessment of Alertness/Sedation (MOAA/S) scale and the Automated Responsiveness Monitor (ARM) device. The MOAA scale assess...

Bacteria beat the heat

...re, might have implications for future attempts to adjust crops to differing climate conditions or improve enzyme efficiency in industrial processes. The team compared two different kinds of bacteria ?one found in moderate environments and the other, an intense-heat lover. Both were photosynthetic (that ...

New fruit fly protein illuminates circadian response to light

Weighting cancer drugs to make them hit tumors harder

...ofessor of biomedical engineering at Duke. "We can adjust the weight higher or lower depending upon where we want the drug to concentrate." Even drugs with vastly elevated molecular weights � 2 million molecular weight -- achieved better concentrations in tumors than a lower molecular weight, the study s...

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

Protein 'nanosprings' most resilient found in nature

...enerated. Cells have to recognize those forces and adjust accordingly." The tension created by the ankyrin springs could allow for very rapid translation of mechanical forces into biochemical signals, he said. The proteins' spring-like properties could also be important for furthering the development of n...

Spring migration of pink-footed geese under threat

We are already seeing signs of decreasing annual breeding success and decreased summer survival as a result of poor body condition when the geese depart from the spring staging areas. Our mod...

'Sharp' older brains are not the same as younger brains

... cognition had brains that had lost the ability to adjust the force of those synaptic communications, the older rats whose memories remained sharp still had that capacity. Interestingly enough, the successful older rats also relied far less than did younger rats on a synaptic receptor that is linked to a co...

Membrane research opens window to benefits for plants, humans

...gy at Duke University Medical Center -- help cells adjust water content. So far 13 forms of aquaporins have been found in animals and another 35 in plants. Previous work in Tajkorshid's lab has identified how water molecules line up in single file and move as if dancing through open water channels. In less...

Cyberkinetics, Case to develop system to help restore extremity function

Study shows big game hunters, not climate change, killed off sloths

...ate because most species of plants and animals can adjust to changes in temperature. However, the transition between the glacial and inter-glacial period, which resulted in shifts in habitat and the ranges of plants, may have made animal species more vulnerable than they otherwise would have been, he said. ...
