Proteins take on new roles in malaria parasite

...gest biological molecules--hold the cell together, communicate with other cells, process nutrients into energy, and carry out various other jobs. By comparing proteins in different organisms, researchers can identify each protein within cellular pathways. In the case of disease-causing organisms, this can lead t...

Recreating 'Flowers for Algernon' with a happy ending

... reduced Ras activity, the brain cells are able to communicate properly in mice with NF1, allowing normal learning to take place. "NF1 interrupts how cells talk to each other, which results in learning deficits," said Silva. "Statins act on the root of the problem and reverse these deficits. This enables the...

Realising potential of renewable resources wins Queens Award for University of York

...d creativity of its research and its commitment to communicate science to the public. CNAP's founder and Director, Professor Dianna Bowles, said "The award of a Queens Anniversary Prize after just six years of existence is a great honour and credit to all of those who have helped to establish CNAP as a vibrant e...

Student scientists create living bacterial photographs

... an image, a process that requires the bacteria to communicate with each other. They're also working on experiments using a laser to turn on and off single cells, which would give them great control. "If we can hit the cell with a laser, we can manipulate their biology without needles or syringes," says Tabor. ...

Book released on Hurricane Isabel's effect on Chesapeake Bay

... they can predict the effects of future storms and communicate effectively to the public. The findings outlined in this book should be used by scientists and hazard experts for decades," said Bill Dennison, conference organizer and Vice President for Science Applications at UMCES. Not all the effects of Hurr...

Algal protein in worm neurons allows remote control of behavior by light

...es the way for better understanding of how neurons communicate with each other, and with muscles, to regulate behavior in intact, living organisms. Generally speaking, detailed information about the activity and function of specific neurons during particular behaviors has been difficult to achieve in undissected...

Research tracks whales by listening to sounds

...guage' that different populations of whales use to communicate with each other, or if they come from a confused juvenile who hasn't completely learned the complexities of communicating." Scientists began hearing whale sounds several years ago on a U.S. Navy hydrophone network. The hydrophone system called the ...

Nobelist discovers antidepressant protein in mouse brain

...the January 6, 2005 issue of Science. Brain cells communicate with each other by secreting messengers, such as serotonin, which bind to receptors located on the surface of receiving cells. Serotonin selective reuptake inhibitors (SSRIs), medications commonly prescribed for anxiety and depression, compensate for...

Zebra finches remember songs dad sang

...language, they're different," Vicario says. "Calls communicate information about food and predators, and males and females both use them," he says. "A song is a vocal behavior used in male-male interactions and in courtship of females, and in most songbird species, only the male sings." A young zebra finch will ...

ACS Chemistry Enterprise 2015 report predicts strong growth, expanding markets

A greater fraction of chemical manufacturing will take place in Asia, but investment returns from the global enterprise will flow back to the United States. As the standard of living increases i...

British blackcurrants beat Alzheimer's

...s cell signaling pathways that help neuronal cells communicate with each other.' Dilip's team recently demonstrated the potent protective effect of blackcurrant compounds on cultured human promyeloyte and neuroblastoma cells assaulted by hydrogen peroxide (JSFA doi: 10.1002/jsfa.0247)....

Drug resistance may travel same path as quorum sensing

... with drugs, but the cells just make more pumps to communicate better. The effect is that they get rid of the drug," said Zechiedrich. Instead of bacterial pumps sending out the usual communication signals, they send out drug instead inadvertently blocking the ability of the drug to kill the bacteria. This does...

National Inventors Hall of Fame announces 2006 inductees

...rior to its creation, moving trains were unable to communicate with each other or with rail stations. Inventors may be nominated by anyone for induction into the Hall of Fame, but they must hold a U.S. patent to be considered. The nominee's invention must have contributed to the welfare of society and have prom...

U of MN researchers develop way to visualize synchronized interactions of nerve cells in the brain

...etter evaluate how the nerve networks in the brain communicate and interact with one another, researchers used magnetoencephalography (MEG) to record, with 1- millisecond temporal resolution, tiny magnetic fields from the brain during a short period of time. They studied this interaction in research subjects wh...
