WEST LAFAYETTE, Ind. – Researchers have shown how arrays of tiny "plasmonic nanoantennas" are able to precisely manipulate light in new ways that could make possible a range of optical innovations such as more powerful microscopes, telecommunications and computers. The researchers at Purdue University used the nanoantennas to abruptly change a property of light called its phase. Light is transmitted as waves analogous to waves of water, which have high and low points. The phase defines these high and low points of light. "By abruptly changing the phase we ...

Maintaining balance is crucial. In Drosophila, the common fruit fly, the creation and maintenance of the blood supply requires such balance. UCLA stem cell scientists have now uncovered that two-way signaling from two different sets of cells is necessary for that balance, both to ensure enough blood cells are made to respond to injury and infection and that the blood progenitor cell population remains available for future needs. The stem cell-like blood progenitor cells – which contribute to the cells of the adult fruit fly's blood supply – receive signals from cells ...

WORCESTER, Mass. – Small, mobile sequences of DNA left over from viruses, called transposons or "jumping genes" because of their ability to move around the genome, pose a significant threat to the genetic integrity and stability of an organism. Considered genetic parasites, these transposable elements are believed to comprise as much as 50 percent of the human genome. Because of the damage transposons can do to an organism's DNA, an immune-like response has evolved to turn off, or silence, these mobile genetic elements. New research published in the journal Cell by the ...

CHAPEL HILL, N.C. – The HIV Prevention Trials Network 052 study, led by Myron S. Cohen, MD of the University of North Carolina at Chapel Hill, has been named the 2011 Breakthrough of the Year by the journal Science. HPTN 052 evaluated whether antiretroviral drugs can prevent sexual transmission of HIV among couples in which one partner has HIV and the other does not. The research found that early treatment with antiretroviral therapy reduced HIV transmission in couples by at least 96 percent. The study was funded by the National Institute of Allergy and Infectious Diseases, ...

December 22, 2011—(BRONX, NY) —Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered the first known mechanism by which cells control the survival of messenger RNA (mRNA) —arguably biology's most important molecule. The findings pertain to mRNAs that help regulate cell division and could therefore have implications for reversing cancer's out-of-control cell division. The research is described in today's online edition of the journal Cell. "The fate of the mRNA molecules we studied resembles a Greek tragedy," said the study's senior ...

Regular use of fluoride-containing toothpaste and mouthwash has long been known to strengthen the enamel on teeth. But new research by Howard Hughes Medical Institute (HHMI) scientists finds that fluoride also has dramatic effects on bacteria inside the mouth -- including those that form plaque and can cause cavities. HHMI researcher Ronald Breaker of Yale University has discovered the cellular chain of events that occurs inside a bacterium after it encounters fluoride in its environment. His team's findings reveal that many bacteria try to fend off fluoride – which the ...

On Tuesday December 6th an organization called the Flood Sisters hosted an annual Holiday Fashion Show Benefit to support their national kidney foundation. The organization, started by three sisters, is designed to support those willing to donate kidneys as well as those awaiting transplants. They believe that no one should have to suffer through painful treatments while waiting for an expendable organ. The event was held at the Scandinavia House ...

Using a mouse model, Heidelberg University Hospital researchers have for the first time successfully treated a severe congenital disorder in which sugar metabolism is disturbed. The team headed by Prof. Christian Körner, group leader at the Center for Child and Adolescent Medicine, demonstrated that if female mice are given mannose with their drinking water prior to mating and during pregnancy, their offspring will develop normally even if they carry the genetic mutation for the congenital disorder. The team's outstanding work will contribute to better understanding of ...

When the Mountains Call . . . . . . don't climb too fast! Lack of acclimatization and excessively rapid ascent are the main risk factors for acute mountain sickness, as Kai Schommer and Peter Bärtsch explain in this issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2011; 108 [49]: 839-48). More and more tourists are climbing up mountains that are 5000 to almost 7000 meters high, such as Kilimanjaro, without any prior experience at high altitudes. The low oxygen content in the air can cause altitude sicknesses of various kinds. For example, sudden vomiting ...

The researchers evaluated the role of Mediterranean diet ingredients in the prevention and mitigation of cell damage. Oleic acid and hydroxytyrosol –present in a particularly high concentration in virgin olive oil– and n-3 polyunsaturated fatty acids –found in fish– affect the cellular mechanisms involved in the development of acute pancreatitis, a disease of oxidative-inflammatory etiology. Therefore, oleic acid and hydroxytyrosol can be considered potential functional ingredients, as they may prevent or mitigate this disease. Such was the conclusion drawn in a study ...

The entire Hawaiian population of the peat moss Sphagnum palustre appears to be a clone that has been in existence for some 50,000 years researchers have discovered. The study is published in New Phytologist. Among the most long-lived of organisms, every plant of the Hawaiian population appears to have been produced by vegetative rather than sexual propagation and can be traced back to a single parent. Surprisingly, the genetic diversity of the Hawaiian clone is comparable to that detected in populations of S. palustre that do propagate sexually and occur across vaster ...

Physicists at Harvard University have realized a new way to cool synthetic materials by employing a quantum algorithm to remove excess energy. The research, published this week in the journal Nature, is the first application of such an "algorithmic cooling" technique to ultra-cold atomic gases, opening new possibilities from materials science to quantum computation. "Ultracold atoms are the coldest objects in the known universe," explains senior author Markus Greiner, associate professor of Physics at Harvard. "Their temperature is only a billionth of a degree above absolute ...

A compound produced from fish oil that appears to target leukemia stem cells could lead to a cure for the disease, according to Penn State researchers. The compound -- delta-12-protaglandin J3, or D12-PGJ3 -- targeted and killed the stem cells of chronic myelogenous leukemia, or CML, in mice, said Sandeep Prabhu, associate professor of immunology and molecular toxicology in the Department of Veterinary and Medical Sciences. The compound is produced from EPA -- Eicosapentaenoic Acid -- an Omega-3 fatty acid found in fish and in fish oil, he said. "Research in the past ...

This press release is available in German.The Earth wobbles. Like a spinning top touched in mid-spin, its rotational axis fluctuates in relation to space. This is partly caused by gravitation from the sun and the moon. At the same time, the Earth's rotational axis constantly changes relative to the Earth's surface. On the one hand, this is caused by variation in atmospheric pressure, ocean loading and wind. These elements combine in an effect known as the Chandler wobble to create polar motion. Named after the scientist who discovered it, this phenomenon has a period of ...

ATLANTA -- A new study finds that while colorectal cancer mortality rates dropped in the most recent two decades for every stage in both African Americans and whites, the decreases were smaller for African Americans, particularly for distant stage disease. The authors say concerted efforts to prevent or detect colorectal cancer at earlier stages in blacks could improve worsening black-white disparities. Before 1980, colorectal cancer mortality rates for African Americans were lower than those for whites. Since then, however, the pattern of CRC mortality rates has reversed ...

The study showed that the onset of age-related disorders and disabilities could be delayed or prevented by ...

In every state but New Hampshire, drivers are required by law to carry liability insurance or some other proof of financial responsibility. This coverage ensures that those injured in motor vehicle accidents have resources available to compensate them for medical bills, wages lost due to an inability to work and other losses arising out of a crash. Adequate insurance coverage also protects those who carry it, even if they are not injured: drivers who cause an accident but lack coverage must pay out of pocket to compensate victims. Yet, according to an Insurance Research ...

Hamilton, ON (Dec. 22, 2011) - Drugs used to overcome cancer may also combat antibiotic resistance, finds a new study led by Gerry Wright, scientific director of the Michael G. DeGroote Institute for Infectious Disease Research at McMaster University.
