CHAMPAIGN, Ill. — A new process for creating ultrathin, ultrasmall inorganic light-emitting diodes (LEDs) and assembling them into large arrays offers new classes of lighting and display systems with interesting properties, such as see-through construction and mechanical flexibility, that would be impossible to achieve with existing technologies.

In the latest proof that the oceans continue to offer remarkable findings and much of their vastness remains to be explored, scientists at Scripps Institution of Oceanography at UC San Diego and their colleagues have discovered a unique group of worms that live in the depths of the ocean.
The discoveries feature worms—nicknamed "green bombers"—that can release body parts that produce a brilliant green bioluminescent display.
The discovery is described in the August 21 issue of the journal Science and is led by Karen Osborn of Scripps Oceanography.

The term "beneficial virus" sounds like an oxymoron.
But for pea aphids under attack by parasitic wasps, carrying infected bacteria is the difference between life and a slow death, according to new research.
The wasps lay eggs inside the aphids, and the wasp larvae eat the living aphids from the inside out.
"A parasitoid death would be a very gruesome death," said first author Kerry M. Oliver. "It's like the movie 'Alien' where this thing grows inside of you and then ruptures out of you and kills you."
CLEMSON -- Optimal control of the spread of the seasonal flu and H1N1 is achieved by prioritizing vaccinations for schoolchildren and for adults aged 30 to 39 in the United States. Those are the findings of a new study by Clemson University mathematician Jan Medlock and colleague Alison Galvani of the Yale University School of Medicine.
New Haven, Conn. —With the seasonal flu season approaching and uncertainty over whether swine flu will become more severe, new research published by Yale School of Public Health has found that more people are likely to avoid illness if vaccines are given out first to those most likely to transmit viruses, rather than to those at highest risk for complications. This research differs from current vaccination recommendations of the Centers for Disease Control (CDC) and the Advisory Committee on Immunization Practices (ACIP).
A new study finds that young muskoxen conserve heat almost as well as adults, a finding that runs contrary to a longstanding assumption among scientists that young animals should be more vulnerable in extreme cold. The study, by biologist Adam Munn from the University of Sydney, Australia, will be published in the forthcoming issue of Physiological and Biochemical Zoology.
In middle-aged women, visceral fat, more commonly called belly fat, is known to be a significant risk factor for cardiovascular disease, but what causes visceral fat to accumulate?
The culprit is likely not age, as is commonly believed, but the change in hormone balance that occurs during the menopause transition, according to researchers at Rush University Medical Center.
Scientists have uncovered a vital link in the chain of events that gives stem cells their remarkable properties.
Researchers from the Wellcome Trust Centre for Stem Cell Research at the University of Cambridge have pinpointed the final step in a complex process that gives embryonic stem cells their unique ability to develop into any of the different types of cells in the body (from liver cells to skin cells). Their findings, published today in the journal Cell, have important implications for efforts to harness the power of stem cells for medical applications.
MADISON — Success in soccer sometimes comes with "bending it like Beckham." Success in cellular fusion — as occurs at the moment of conception and when nerve cells exchange neurotransmitters — requires that a membrane be bent before the merging process can begin, University of Wisconsin-Madison researchers have shown.
CAMBRIDGE, Mass. (August 20, 2009) – The tail ends of cellular protein templates, regions often thought relatively inconsequential, may actually play a role in preventing normal cells from becoming cancerous.
The finding from scientists at Whitehead Institute for Biomedical research is reported in the August 20 edition of Cell.
For the first time, it has been shown that patients who receive night home hemodialysis live just as long as those who receive kidney transplants from deceased donors.
By studying the intricate mechanisms at work in protein production, a Princeton-led team has discovered why certain kinds of antibiotics are so effective. In doing so, they also have discovered how one protein protects against cell death, shedding light on a natural cancer-fighting process.
A research team led by U of T Mississauga scientists has developed a new way to split up a dangerous pair of cancer proteins, a finding that could ultimately lead to chemotherapy that is more effective and has fewer side effects.
Polycystic ovary syndrome, a common condition among women, can be relieved by the use of acupuncture and exercise. This has been shown by a recent study at the Sahlgrenska Academy, University of Gothenburg, Sweden.
