MERIS monitoring tracks planetary photosynthesis levels

...observations from Envisat's MERIS sensor are being combined with a sophisticated processing algorithm and powerful Grid computing to reveal global photosynthesis activity on land. This permits researchers to trace the state of health of terrestrial plant cover, identifying areas under stress and assessing dam...

Team of international scientists departs today to discover the unknown in China's Himalayan region

... of the Earth's surface (roughly equivalent to the combined areas of the five largest U.S. states). This habitat originally covered 15.7 percent of the Earth's surface, an area equivalent in size to Russia and Australia combined. New hotspot analysis shows that an estimated 50 percent of all vascular plants a...

Microbe has huge role in ocean life, carbon cycle

... SAR11, a group of bacteria so dominant that their combined weight exceeds that of all the fish in the world's oceans. In a marine environment that's low in nutrients and other resources, they are able to survive and replicate in extraordinary numbers ?a milliliter of sea water off the Oregon coast might cont...

New bioinformatics technique for systematically analyzing key regions in DNA that help control gene activity

...e LCB. "Thus we now know that binding sites can be combined to allow a large number of expression outcomes using relatively few transcription factors." Others collaborating in the project were Jerzy Tiuryn of the Faculty of Mathematics, Informatics, and Mechanics at Warsaw University in Poland; Bartosz Wilcz...

Clear rules needed to govern deep sea bioprospecting: UNU

... economic potential of deep seabed bioprospecting, combined with a strong sensitivity to countries' freedoms in international areas." "Ethical concerns have been raised with regard to the status of deep seabed genetic resources," says Salvatore Arico of UNESCO, a Visiting Research Fellow at UNU-IAS and a lea...

A Father’s Day Gift: Free DNA Paternity Testing

Helping in a selfish world

...efend the young and the territory. The researchers combined behavioural observations with genetic analyses of relatedness in these fish groups and found that under specific ecological and demographic conditions unrelated individuals must "pay-to-stay" in the group and therefore may help more. "This fish spec...

Results of world's first gene therapy trial for arthritis show approach safe, feasible

...?as a more recent French trial for X-linked severe combined immunodeficiency (X-SCID) in which three children later developed leukemia, the researchers point out that this is the only similarity between the two trials. The studies were concerned with different genes and with different targets, and in the arth...

Tadpole soon to help in the fight against cancer and lymphedema

... of gene per gene, which complicates revealing the combined action between various genetic factors. For efficient research smaller model organisms are used, such as the zebrafish, which is popular in the study of the blood vessel system. But the zebrafish also offers little comfort, as it does not have any ly...

Evolution of life on Earth may hold key to finding life in outer space

...breakthroughs in biology in the last 100 years. A combined UH/NASA night with two free screenings of "Fantasy Worlds" for UH students, faculty and staff and NASA employees will be held 6 to 8 p.m., Tuesday, Aug. 23, at the museum. Otherwise, tickets for the show are $5 for adults, $3.50 for children (3-11) a...

Life's origins were easier than was thought

...d life on earth, there were organic molecules that combined to produce the first nucleic acid chains, which were the first elements able to self-replicate. According to one of the more accepted theories, these molecules were ribonucleic acid (RNA) chains, a molecule that is practically identical to DNA and th...

Genes linked to treatment resistance in children with leukemia

... to be prognostic for CNS relapse, especially when combined with a VDR intron 8 genotype. In the low-risk group, the TYMS 3/3 genotype was a risk factor. For children with these unfavorable genotypes, a potential solution may be using drugs that are not affected by these particular enzymes or increasing the ...

Molecular mechanism of feather formation found

...ental patterning in animals years ago. Through the combined efforts of Meinhardt, Richard Prum of Yale University and Scott Williamson of Cornell University, the model was placed in the context of simulations of growing feathers. The results suggested that a simple interaction between Shh and Bmp2 is suffici...

India's smoking gun: Dino-killing eruptions

...P). To test that hypothesis, the researchers have combined already known ages of the traps gathered from radiometric dating with magnetic fields frozen in the rocks. Volcanic rocks record information about the Earth's magnetic field with magnetic minerals that align with Earth's field like millions of tiny c...

Tropical Deforestation affects rainfall in the U.S. and around the globe

...outhern tip of the Arabian Peninsula. However, the combined effect of deforestation in all three regions shifts the greatest precipitation decline in the U.S. to California during the winter season and further increases rainfall in the southern tip of the Arabian Peninsula. Improved understanding of tropical...

Fluoride poisoning in China due to clay, not coal

...uch cheaper than burning large blocks of coal. The combined fuel is used to dry corn before storing it. Corn, however, absorbs more smoke than other grains, such as rice or wheat. Zheng's team found that only 15 per cent of the fluoride released when the coal and clay mixture is burnt comes from the coal. T...

Elusive salamanders have role in developing new sampling models

...physical data about the ponds and their watersheds combined with the presence or absence of salamanders to develop models to identify ponds most likely to support reproduction of the flatwoods salamander. The habitat modeling takes into account numerous environmental and other variables and will be used to i...

Tiny avalanche photodiodes target bioterrorism agents

...Once optimized, these sensitive detectors could be combined with the ultraviolet light-emitting diodes (LEDs) already pioneered by the Center for Quantum Devices to create an inexpensive detection system capable of identifying the unique spectral fingerprints of a biological agent attack. The Northwestern te...

Neurotransmitters signal aggressive cancer, offer potential for early diagnosis

...ion about how active each gene in tumors is. They combined the mouse data with parallel data from 182 human tumors. Then, the gene-activity data was fed into sophisticated software that supplied the researchers with a prediction about which metabolic reactions were revved up in the tumors and which were slow...

North & South American researchers find architectural abnormalities in T. cruzi ribosome

...research scholar from Buenos Aires, Argentina have combined their expertise to identify two peculiar features of the protein-making machinery of the parasite that causes Chagas disease. Their findings could help scientists develop a safe and effective drug for the disease, whose cardiac complications kill up ...
