Mitochondria findings may help beat wide range of disease

...ted mitochondria that had been removed from cells, observing them in test tubes using both light and electron microscopy. This cell-free approach allowed researchers a first-ever glimpse into the sequence of events underlying outer and inner membrane fusion. What they discovered -- that mitochondria removed ...

UF scientist: 'Brain' in a dish acts as autopilot, living computer

... signals from each other to control our bodies. By observing how the nerve cells interact with the simulator, scientists can decode how a neural network establishes connections and begins to compute, DeMarse said. When DeMarse first puts the neurons in the dish, they look like little more than grains of sand...

Though the separate makes of automobile have changed and diversified over time, they share features that were present in their conceptual ancestor: four rubber tires, a windshield, and an intern...

NJIT physicists expect new super lens to reveal first light by early 2006

...ssue of Science, Goode and his team argued that by observing earthshine for eight years, they had witnessed first a gradual decline in the earth's reflectance, which although it grew sharper in the late 1990s, reversed itself in the past three years. There seemed to be a decadal natural variability of the clim...

Yerkes researchers discover baisis for determining handedness in chimpanzees

...he area of the brain that controls language. After observing hand preference in chimpanzees, which have no comparable language capabilities, we concluded there must be another reason for handedness. Because human and chimpanzee brain structures are so similar, we wanted to determine if human handedness evolved...

Holes in fossil shells show effects of competition and evolution

...onsequences of extinction and recovery, by closely observing how individual species interact with each other. "Our work shows that scientists have been looking at only half the story when they talk about the consequences of extinction," said Gregory P. Dietl , a post-doctoral fellow in geology and geophysic...

NJIT astrophysicist who revived earthshine named fellow of American Physical Society

After observing the increased amount of COX-2 in the oral mucosa of smokers, Dannenberg and his team of collaborating scientists exposed cells in culture to tobacco smoke to define the mechanism underlying smoke-induced elevation of COX-2. The researchers determine...

Chimpanzees show quality of relationship drives sense of fairness

... National Primate Research Center in Atlanta. By observing variability in chimpanzees' responses to inequity, Sarah Brosnan, PhD, and Frans de Waal, PhD, both researchers in Yerkes' Division of Psychobiology and the Yerkes-based Living Links Center, determined the chimpanzees' responses depended upon the str...

Spectroscopy for the real world

.... But until recently, there was no way of directly observing and quantifying this phenomenon. Enter the high-pressure photoelectron spectroscopy system, a second-generation instrument that began operating at one of the ALS's beamlines (11.0.2) last year. (A first-generation system was developed in 2000). Lik...

Zhou and his colleagues also suggest that noise might usefully be used to control chemical reactions. They explain that random disturbances in industrial mixing tanks could be promoted to make a reaction proceed m...

New science sheds light on rebuilding fisheries

...erkeley started investigating this advantage after observing Pacific rockfish spawning patterns. He noticed that older females spawned early in the season. And when he looked at the next generation of fish, there were years when most of them had birthdates corresponding with these early spawning events. He w...

Bird IQ test takes flight
