Scientists must offer solutions for conserving tropical forests in a rapidly changing world

... globe, while human populations and their economic activities grow. Old-growth forests become agricultural lands, degraded land is abandoned, urbanization intensifies, and the populations of tropical countries will increase by two billion over the next 25 years. But what is happening in protected areas? Global...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

... the geological age of the Anthropocene, where the activities of mankind and its interactions with natural phenomena are the driving force in global climate change. "Next we are hoping for follow-up satellite missions, in particular from geostationary orbit to monitor atmospheric pollution, which has a strong...

Oil spills and climate change double the mortality rate of British seabirds

...t would mean that seabirds are vulnerable to human activities on two counts: oil pollution from tanker spills and changes to the ecosystem as measured by the NAO index and caused by global climate change from man's burning of fossil fuels." ...

Plant gene related to cancer treatment may foster new oncology drugs

...ginally used to identify the gene that directs the activities of PIN1, these proteins are members of the major protein family, called facilators, that aid processes such as hormone transport. Recent evidence suggests that teamwork between PGP and PIN proteins determines the direction auxin moves and, therefore...

Deep treasure to be found in Oculina Bank

...ctiveness of, stricter regulations and enforcement activities in the area. The group will also be exploring new portions of the reef revealed by a recently developed high-resolution seafloor map. The Oculina reefs, in depths from 250 to 300 feet, were built over the past thousand years or so by the delicate iv...

Plants have a double line of defence

...ted from another cell component through the enzyme activities of the PEN2 enzyme, a glycosyl hydrolase. The substance released by it appears to have a fungicidal effect, which kills the pathogen. The researchers, on the other hand, observed that when PEN2 is missing, the plants become more susceptible not only...

Envisat radar surveillance protects endangered prehistoric fish

...utilised for ship detection in a growing number of activities worldwide, including the protection of Icelandic fisheries through the Improving fisheries Monitoring through integrating Passive and Active Satellite-based Technologies (IMPAST) project run by the European Commission's Joint Research Centre (EC-JRC)...

Compound from marine bacteria shows potential as multiple myeloma therapy

...udies, NPI-0052 blocks a wider range of proteasome activities than bortezomib, say the researchers, and works at lower doses. NPI-0052 also appears to be less toxic to normal cells. Bortezomib is currently given by intravenous infusion. "NPI-0052 can be given orally, although the first clinical trials will be...

Implantable pumps extend lives of patients too sick for transplant

...Dallas. "We had patients who were doing the normal activities of life, such driving cars, fishing and golfing." Patients who were on the LVADs scored significantly higher on standard measures of quality of life than patients in the control group, Rogers said. "This is a remarkably ill group of patients," Roge...

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

...-called channel proteins play central roles in the activities of neurons and muscle cells, and while some channel proteins are sensitive to chemicals or electrical signals, ChR2 and its relatives are controlled directly by certain wavelengths of light, making them ideal for remote control in the laboratory. In...

Meditation associated with structural changes in brain

...earchers found that regions involved in the mental activities that characterize Insight meditation were thicker in the meditators than in the controls, the first evidence that alterations in brain structure may be associated with meditation. They also found that, in an area associated with the integration of e...

Health of Acehnese reefs in the wake of the tsunami shows human impacts more harmful

...n the region and was clearly correlated with human activities prior to the tsunami. In areas where fishing has been controlled, such as the Marine Protected Area on Pulau Weh and reefs managed under the traditional Acehnese system of Panglima Laut, coral cover was high. In contrast, reefs exposed to destructive...

Scientists show how thinking can harm brain cells

...ulses that are passed between cells during routine activities like learning and memory can become toxic. Instead of triggering the formation of memories, these impulses can inflict injury on neurons and disrupt neurologic function. Understanding this mechanism could provide a new path for drugs to treat the di...

Wild birds help to create human flu vaccine

...fluenza virus. Focusing resources on the hubs and activities where humans, livestock, and wildlife come into cl.... To contain this potential epidemic, prevention activities must include better management practices in farms, especially those that are small and open-air wher...

GROWing the next generation of water recycling plants

... waste washing water, which can then be reused for activities such as flushing the toilet. GROW is the brainchild of Chris Shirley-Smith, whose company Water Works UK is collaborating with Imperial College London and Cranfield University. The researchers are funded by the Engineering and Physical Sciences Res...

Understanding the oceans microbes is key to the Earth's future

...cluding the roles of both climate change and human activities on the populations and processes of marine microbes. The report also recommends fostering multidisciplinary collaborations and training as well as the development of a comprehensive marine microbiology textbook. "Innovative approaches in research, ...

Yale scientists decipher 'wiring pattern' of cell signaling networks

...he regulatory networks governing the functions and activities of the kinases in the yeast cell. The map shows several distinct patterns. "It was a little like having all the pieces of an airplane separated out, and not knowing how those pieces function together to create an airplane and make it fly," said Snyd...

UCSD study finds anthrax toxins also harmful to fruit flies

A real time look at interactions between RNA and proteins

...teins, but also observe–in real-time–the intricate activities of these special molecules that make them key players in managing some of the cell's most basic functions. Researchers at the University of Pennsylvania School of Medicine who developed the new technology see this advance as one of the next logical s...

Frog’s ear canal may provide insights for understanding human hearing loss

...unds. The scientists then measured the electrical activities in A. tormotus' midbrain that is involved in sound processing and found marked electrical responses to sounds extending into the ultrasonic range -- both in the averaged response of a population of nerve cells in the brain and in single nerve cells -...
