Art and music for the birds

...species around us,” she adds. The bird listening stations are part of the exhibition “Inside/Outside: Habitat” on view at the Abington Arts Center’s Sculpture Park in Jenkintown, Pa., through Wednesday, Nov. 21. Visitors of the interactive exhibit receive a schedule of songs emitting from each station, whic...

Corals that can fight global warming may one day help fragile reefs

...rking group is an international collaboration with stations in the Caribbean, Philippines, Australia and East Africa that seeks to understand how rising ocean temperatures (which are monitored with high-resolution satellite detectors) are related to lethal coral reef epidemics. The warm temperatures that ha...

Need oxygen? Cells know how to spend and save

...ced by passing electrons through a series of relay stations called cytochromes until they eventually join with oxygen to form water. This final step is directed by the protein cytochrome coxidase, or COX for short. If electrons react with oxygen before reaching COX, they generate "free radicals" that can dam...

Cocaine high caused by interference in neuronal receiving stations

...ect to interactions between two types of receiving stations in neurons for nerve signals from their neighbors. The researchers' studies in rats found that when the animals received cocaine, a component of a receptor for the neurotransmitter dopamine tends to grab onto a component of a receptor for glutamate. ...

Changing length of days reverses how estrogen affects aggressiveness in mice

...en receptor beta. These receptors are like docking stations that send signals from the estrogen molecules into the cells. One hypothesis had been that one type of receptor was important in winter-like short days, and the other receptor in summer-like long days ?which could help begin to explain why estroge...

NASA study: Alaskan fires affected Houston air quality in 2004

...NASA satellites, aircraft, and a network of ground stations provided unprecedented insight into the origins of locally poor air quality in Houston on those two days," Morris said. Houston frequently exceeds federal standards for ground-level ozone. On 52 days in 2005, Houston's air quality violated the eight...

3-D ultrasound scanner could guide robotic surgeries

...s, a capability that could prove valuable in space stations or other remote locations. "It's the first time, to our knowledge, that anyone has used the information in a 3-D ultrasound scan to actually guide a robot," said Stephen Smith, professor of biomedical engineering at Duke's Pratt School of Engineeri...

Scientists find Antarctic ozone hole to recover later than expected

...eries satellites, and data captured by NOAA ground stations and weather balloons to create the new prediction model. ...

Common practices at petting zoos put visitors at risk

...ment of Health monitored the use of hand-sanitizer stations at the exits of petting zoos in middle Tennessee. Of the 1,700 visitors, approximately 62% did not use the hand-sanitizer station after visiting the petting zoo. Both studies also noted that a sizeable percentage of petting zoo visitors were also e...

High-tech tags on marine animals yield valuable data for biologists and oceanographers

...o be constantly updated with new data from weather stations all over the country," he said. The researchers are also gaining new insights into the lives of California sea lions, said Michael Weise, a graduate student working with Costa on the sea lion studies. "This technology brings a whole new dimension t...

2005 was the warmest year in a century

... the NASA analysis. Although there are few weather stations in the Arctic, the available data indicate that 20..., the scientists use temperature data from weather stations on land, satellite measurements of sea surface temperature since 1982, and data from ships for earli...

How the neuron sprouts its branches

...ors. Dendritic connections are the basic receiving stations by which neurons form the signaling networks that constitute the brain's circuitry. Such basic insights into neuronal growth will help researchers better understand brain development in children, as well as aid efforts to restore neuronal connection...

The brain is broadly wired for reproduction

... in both directions between GnRH neurons and relay stations in the brain that process signals from both the olfactory and vomeronasal systems, said Buck. In mice and other mammals, the olfactory and vomeronasal systems are distinct pathways for sensing chemicals in the environment. While the main olfactory s...

Dangerous tricksters: Some bacterie use immune cells to reproduce

...ophages which might otherwise digest them. Action stations in the horse's lung! A bacterium has just been inhaled into a horse's bronchial tubes, and immune cells are quickly recruited to the spot to neutralise the intruder. Macrophages, cells whose job is to devour such intruders, are attracted by substanc...

Researcher says flu responders can learn from 1918 epidemic

...ario, with dead bodies piling up outside of police stations and others dumped into trench graves. "Obviously, not every city had the same experience," Higgins said. "There were really no successes. You could only talk about degrees of failure and success." ...

NCAR analysis shows widespread pollution from 2004 wildfires

...nuing to look at data taken last year at observing stations as far away as the Azores in order to track the movement of carbon monoxide and ozone from the wildfires. As a follow-up, she and other scientists plan to use a similar combination of observations, modeling, and numerical techniques to look at both n...

Errors in the measurement of global warming corrected

...information has been collected twice each day from stations around the world at local times that correspond to 00:00 and 12:00 Greenwich Mean Time. Some measurements were taken in daylight, others in darkness. "Even though models predict a close link between atmospheric and surface temperatures, there has be...

Sensor web simulation investigates technique to improve prediction of pollution across the globe

...ies. NASA is trying to tie together satellites and stations on the ground to develop a "sensor web" to track this pollution and improve air quality forecasts. Understanding how tropospheric or near-surface-level ozone is produced, distributed and transported from city to city, region to region and continent ...
