Alternative Theory Of Information Processing In The Cortex
- ScienceDaily
- 08/10/20 06:55
With remarkable precision, neurons in the sound-processing part of the brain's cortex fire electrochemical pulses or "spikes" in sync with cues they receive from other neurons. Neuroscientists have demonstrated that "spike timing" in cortical neurons can influence behavior in rats when signals are separated by as little as three milliseconds. This discovery helps make the case for an alternate...
Buckypapers Clarify Electrical, Optical Behavior Of Nanotubes

- 08/10/20 06:55
New varieties of sugarcane and other crops adapted to the U.S. Gulf Coast region are being developed for use in making ethanol as a cleaner-burning alternative to gasoline.
Aspirin Does Not Prevent Heart Attacks In Patients With Diabetes, Study Suggests
- ScienceDaily
- 08/10/20 06:55
Taking regular aspirin and antioxidant supplements does not prevent heart attacks even in high risk groups with diabetes and asymptomatic arterial disease, and aspirin should only be given to patients with established heart disease, stroke or limb arterial disease, according to a new...
New Fossil Reveals Primates Lingered In Texas
- ScienceDaily
- 08/10/20 06:55
More than 40 million years ago, primates preferred Texas to northern climates that were significantly cooling, according to new fossil evidence.
Worms' Nervous System Shown To Alert Immune System
- ScienceDaily
- 08/10/20 06:55
The nervous system and the immune system have something in common. Each has evolved to react quickly to environmental cues. Because the nervous system is able to detect some of these cues at a distance, it sometimes can sense trouble earlier than the immune system, which has to wait until the pathogen invades the organism. Now, geneticists have shown that, indeed, the two systems talk to one...
First Tunable, 'Noiseless' Amplifier May Boost Quantum Computing, Communications
- ScienceDaily
- 08/10/20 06:55
Researchers have made the first tunable 'noiseless' amplifier. By significantly reducing the uncertainty in delicate measurements of microwave signals, the new amplifier could boost the speed and precision of quantum computing and communications systems.
'A Dinosaur Dance Floor'
- ScienceDaily
- 08/10/20 06:00
Geologists identified an amazing concentration of dinosaur footprints and tail-drag marks that they call "a dinosaur dance floor," located in a wilderness on the Arizona-Utah border where there was a sandy desert oasis 190 million years ago.
Alternative Fuels May Drain Dwindling Water Supplies
- ScienceDaily
- 08/10/20 06:00
As the search for new fuels intensifies, researchers in Texas report that switching to certain alternative fuels to power cars, trucks, and SUVs may require the use of much more water than conventional petroleum-based gasoline and diesel. The findings suggest that producing alternative fuels could strain already limited water supplies in some regions of the...
First Inhabitants Of Caribbean Brought Drug Heirlooms With Them
