Protein behind autumn color splendor identified

...arts to disappear from the leaves of plants. This reveals the yellow and red pigments that bring us the explosion of colors we now have in store. A research team at Ume's Plant Science Center (UPSC) has now identified a protein that helps bring out the color splendor of plants in the fall. The research te...

The earliest animals had human-like genes

...fly genes would be more ancient. The current study reveals the opposite: early animals already had a lot of introns, and quickly-evolving species like insects have lost most of them. To discover what early animals were like, scientists usually compare their descendents. This is difficult when comparing dist...

Mammalian Transcriptome Mapped

...was once thought to be rare, but the transcriptome reveals that it takes place to an extent that few could have imagined. "Instead of it being a rare phenomenon, we are showing that it is a massively abundant phenomenon," says Wahlestedt. "It is the rule rather than the exception." This discovery has signif...

Einstein scientists discover how protein crucial for motion is synthesised at the right place in the cell

...ein responsible for cell motility. This new study reveals another key role for ZBP1: Not only does ZBP1 bind to actin messenger RNA and guide it to the cell's periphery, but it also helps regulate where in the cell the messenger RNA is translated into actin. "The ZBP1 bound to actin's messenger RNA acts ...

Seafloor creatures destroyed by ice action during ice ages

... ice in the oceans? Research by marine scientists reveals that it was a time of mass destruction as whole communities of animals were wiped out by ice sheets scouring the sea floor. In the past it has been thought that these ecosystems somehow dodged extinction by recolonising from nearby habitats that esc...

Gene therapy may protect normal tissues during radiation retreatment for lung cancer

... ice in the oceans? Research by marine scientists reveals that it was a time of mass destruction as whole communities of animals were wiped out by ice sheets scouring the sea floor. In the past it has been thought that these ecosystems somehow dodged extinction by recolonising from nearby habitats that esc...

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

... performed by ERS-2's GOME and Envisat's SCIAMACHY reveals the world's largest amount of NO2 hanging above Beijing and northeast China, as reported in Nature this week. As part of ESA's Dragon Programme, European and Chinese researchers are using results returned from the Global Ozone Mapping Experiment (GO...

Center releases new public survey on stem cells

...urvey of 2,212 Americans conducted September 9-19, reveals a public opinion landscape that bears little resemblance to the polarized, deep moral divide expressed on the floor of the Congress and in the op-ed pages of American newspapers. The survey found wide support for embryonic stem cell (ESC) research t...

Male elephants woo females with precise chemistry

...l activity and increased aggression. "This study reveals the precision and specificity of inter-animal signaling possible," co-author L.E.L. "Bets" Rasmussen, Ph.D., research professor of environmental and biomolecular systems, OHSU OGI School of Science & Engineering, said of the study published in th...

Scientists observe how a close bond activates the immune system

...lished in the November 18, 2005, issue of Science, reveals how T cells analyze and react to the signals of infection at the immunological synapse. Every T cell wears a unique molecule, called a T cell antigen receptor, on its surface that it uses to detect pieces of foreign proteins called antigens. These ...

Scientists move forward understanding of schizophrenia

... the pharmaceutical company Merck Sharpe and Dohme reveals that damage to the gene PDE4B is also seen to increase the risk of developing mental illness. PDE4B was already known to play an important role in how the brain thinks and builds memories, but had not previously been linked to mental disorder. In add...

Scientists map one of biology's critical light-sensing structures

...he protein. That three-dimensional portrait, which reveals the atom-by-atom configuration of the molecule, is the key to understanding the "nuts and bolts" of how the photoreceptor senses light and triggers a series of downstream events that control growth and development, according to Katrina Forest, the ot...

Genetic testing still smart choice, despite uncertainties

... of the American Society of Reproductive Medicine, reveals the technique is actually highly reliable. But because there is a slim chance a genetic abnormality can cause doctors to misdiagnose embryos, some concerns still need to be addressed, the researchers said. Preimplantation genetic diagnosis has bee...

Cells from amniotic fluid used to tissue-engineer a new trachea

...amniocentesis. And when a prenatal ultrasound exam reveals fetal malformations, amniocentesis is usually recommended. Complications are rare. "In many cases, the amniotic fluid is collected anyway," says Fauza. "It's a precious resource that's thrown out now, but shouldn't be." Less than two tablespoons o...

The brain is broadly wired for reproduction

...'t think anyone ever suspected this complexity. It reveals that GnRH neurons are master integrators of information about the external environment, as well as the internal state of the animal." The studies also suggest that GnRH neurons influence a wide array of brain functions, possibly coordinating those f...

Superconducting magnet attracts molecular research

... the frequency of the spinning motion of the atoms reveals information about the physical, chemical, structural and electronic characteristics of the molecule in solution. Magnetic resonance spectroscopy was first described more than a half century ago, and is related to MRI (magnetic resonance imaging) use...

Birth defects: 8 million annually worldwide

... Toll of Dying and Disabled Children. The report reveals that at least 3.3 million children less than 5 years of age die annually because of serious birth defects, defined as any serious abnormality of structure or function. An estimated 3.2 million of those who survive may be mentally and physically di...

Combination therapy improves AIDS-related lymphoma outcome

... journal of the American Cancer Society, the study reveals that combination therapy showed the greatest benefit for HIV patients suffering from aggressive malignant non-Hodgkin's lymphoma. This benefit was most pronounced in HIV patients without severely impaired immune functions. These so-called "standard r...

Horse antibodies against the bird flu virus H5N1 are effective as treatment in mice

...atory Research ( http://respiratory-research.com ) reveals that a dose of 100 µg of horse anti-serum effectively protects infected mice. These results suggest that anti-H5N1 antibodies developed in horses could potentially be used to prevent death from H5N1 influenza, or as early treatment for the disease, i...
