Brain inflammation may be friend, not foe, for Alzheimer's patients

...ntists can boost IL-1beta in select areas and then watch what happens as the process unfolds. The team expected to see the telltale clumps of material known as amyloid plaques, made up of the peptide amyloid beta, worsen. Instead, to the team’s surprise, the brains of the mice with IL-1beta stuck in ove...

Simulations unravel outer membrane transport mechanism

...Click on the link below the image of the system to watch the results of the simulation.) A second simulation exerted a force near the center of gravity of the luminal domain, pulling it out of the barrel in one piece. This required an enormous input of energy, however. “The force that we applied was ...

New collaborative research reveals chimpanzees can sustain multiple-tradition cultures

... group if you offer chimpanzees the opportunity to watch other groups. It’s a bit like Westerners learning to eat with chopsticks."...

Scientists see DNA get 'sunburned' for the first time

... colleagues in Germany used a special technique to watch strands of DNA in the laboratory sustain damage in real time. They observed the most common chemical reaction among a family of reactions on the DNA molecule that are linked to sunburn, and discovered that this key reaction happens with astoundin...

Bones in motion: Brown scientists to create new 3-D X-ray system

...possible: See inside living humans and animals and watch their bones move in 3-D as they run, fly, jump, sw...?you'll be able to see through skin and muscle and watch a skeleton move in 3-D," said Elizabeth Brainerd, the Brown University biology professor overseeing ...

Scientists identify molecular cause for one form of deafness

...These nematic liquid crystals are commonly used in watch displays and laptop displays. Wong and his colleagues also found that a mixture of mutant espin and normal espin would prevent the structural transition from occurring. If gene expression could turn on the production of just a fraction of normal es...

Massive coral death attributed to earthquake

...Indonesian corals reefs now have another threat to watch out for, and not all reef damage should be immediately attributed to human influences." Many other reefs, particularly in the Pulau Banyak, continue to be damaged by destructive fishing including bombing and the use of cyanide. These practices are...

Gene that makes people 'early to bed and early to rise' demystified

...in," Fu said. "When we fly to Europe, we set our watch ahead several time zones and our watch is back on track," Ptácek added. "We don't understand the [internal] human clock well enough to adva...

Researchers create artificial enzyme that mimics the body's internal engine

...y let the enzyme have only one oxygen molecule and watch what happens." He said that single turnover is like taking a single photograph of an event, while steady turnover is like shooting a movie. Damaged enzymes Once Collman's group had solved the continuous electron supply problem, the scientists...

Sleep disturbances affect classroom performance

...Keep a regular schedule. Don’t read, write, eat, watch TV, talk on the phone or play cards in bed. Do not have any caffeine after lunch. Do not go to bed hungry, but don’t eat a big meal before bedtime either. Avoid any rigorous exercise within six hours of your bedtime. Try to get rid of or deal...

Why is the heart heart-shaped?

...d, by using transgenic zebrafish in which they can watch individual cardiac cells, that cells change size and shape, enlarging and elongating to form the bulges in the heart tube and eventually the chambers. Since the heart is beating as it develops, they asked whether cardiac function influences cell shap...

Do you hear what i see?

...keys that shows enhanced activity when the animals watch a video. This study confirms a number of recent findings but contradicts classical thinking, in which hearing, taste, touch, sight, and smell are each processed in distinct areas of the brain and only later integrated. The new research, led by Chris...

Reversing cancer cells to normal cells

...side the body (making it especially easy to simply watch development), and the fact it develops organs and tissues comparable to those in humans, such as heart, kidney, pancreas, bones and cartilage.) Using the zebrafish model, and the extraordinary technologic advances made in microscopy and molecula...

OHSU researchers demonstrate how white blood cells cannibalize virus-infected cells

...ent dye to stain infected cells, you can literally watch T-cells consume membranes and outer surfaces of diseased cells. As they destroy and cannibalize the fluorescently labeled cells, they become labeled with the fluorescent dye themselves," explained Mark Slifka, Ph.D., a researcher in the VGTI who led ...

Living view in animals shows how cells decide to make proteins

...lar genetics and microbiology. "We were able to watch alternative splicing as it occurred in different tissues," he said. "It’s an excellent example of how experiments in living organisms provide a much more complete picture of how genes and proteins behave than do experiments using cells in culture." ...

Gold nanoparticles prove to be hot stuff

Study provides first look at the 'birth' of a retina cell

...aroop. "Because the cells have been tagged, we can watch them at each step as they develop into mature and functional rods." Kellogg scientists then purified the rods at various stages and generated the profile of genes at each stage. This, for the first time, provided a handle for investigating the precis...

Einstein researchers take the pulse of a gene in living cells

...at for the first time allow scientists to directly watch the behavior of a single gene in real time. Their findings appeared in the current issue of Current Biology. When a gene is expressed or "turned on," genetic information is transferred from DNA into RNA. This process, known as transcription, is cruc...
