Almost two years after the International Astronomical Union (IAU) General Assembly introduced the category of dwarf planets, the IAU, as promised, has decided on a name for transneptunian dwarf planets similar to Pluto.

The name plutoid was proposed by the members of the IAU Committee on Small Body Nomenclature (CSBN), accepted by the Board of Division III, by the IAU Working Group for Planetary System Nomenclature (WGPSN) and approved by the IAU Executive Committee at its recent meeting in Oslo, Norway.

Plutoids are celestial bodies in orbit around the Sun at a distance greater than that of Neptune that have sufficient mass for their self-gravity to overcome rigid body forces so that they assume a hydrostatic equilibrium (near-spherical) shape, and that have not cleared the neighbourhood around their orbit. The two known and named plutoids are Pluto and Eris. It is expected that more plutoids will be named as science progresses and new discoveries are made.

Genetically modified foods are the enemy, say some activists, but organic foods have caused all the salmonella say others. The food safety message is a mess and Americans lack confidence in the system because of it.

A new national study conducted by the Harvard School of Public Health Project on the Public and Biological Security finds that, though there have been food safety incidents in recent years, Americans are confident that the food produced in the United States is safe but have concerns about the safety of imported food produced in some other countries.

The poll found that a majority of Americans believe that the food produced in the U.S. is either very (37%) or somewhat (58%) safe. Only 4% thought US-produced foods were unsafe. When asked about foods available in the U.S. but produced in other countries, fewer than one in ten (6%) considered foods from Canada to be unsafe. In contrast, almost half of Americans (47%) thought food from Mexico was unsafe, and 56% thought this about food from China. Possibly responding to these concerns, about half (53%) of Americans reported at least sometimes looking for information about what countries foods come from when shopping for groceries.

Silicone breasts for a football star's girlfriend, aging Hollywood actresses with doll-like, over-tightened faces - all this could soon be a matter of the past.

Cosmetic surgery is developing into an interdisciplinary medicine of beauty and rejuvenation which has only little use for silicone and scalpel.New cosmetic surgery relies to an important part on minimal-invasive, gentle surgery, done under local anaesthesia. Liposuction by use of microcannulas offers a good example, being easy on the tissue and allowing for precise shaping of body and face, followed by only minimal aftercare.

The second pillar on which new cosmetic surgery rests is the use of body-own stem cells. These allow for lasting breast augmentation without silicone and have made operations such as standard facelift, lid correction and wrinkle treatment with "fillers" obsolete. Stem cells have shown immediate rejuvenating and regenerating local effects and can be used for many aesthetic treatments.

Conserving biodiversity must be considered when developing plans to reduce greenhouse gas emissions from deforestation, researchers warn in a paper today.

The 2007 statistics from the Food and Agriculture Organization of the United Nations indicate that from 1990 to 2005 the world lost 3% of its total forest area, some 13 million hectares per year. The greatest losses were in Latin American and the Caribbean ( 7 % over 15 years or about 16 million hectares per year) Africa (9% over 15 years or 4.4 million hectares per year). Land use change (mostly deforestation) accounts for 18-25% of global annual greenhouse gas emissions.

The United Nations Framework Convention on Climate Change is currently discussing ways of Reducing Emissions from Deforestation and Degradation (REDD) in developing countries. REDD has great potential to deliver benefits for biodiversity and people, as well as for the climate, however it is likely that these benefits will be concentrated in forests with high carbon stocks and that land use change may shift to low-carbon forests and other ecosystems important for biodiversity.

In a report in the current issue of the journal Cell, Dr. Hugo Bellen and colleagues at Baylor College of Medicine along with Dr. Michael Miller from the University of Alabama at Birmingham show how a single mutation in the human form of the VAMP-Associated Protein B (VAPB) contributes to the nerve and muscle breakdown in flies and worms, similar to ALS in humans. They found important clues about what goes wrong in the nerves and muscles of people with amyotrophic lateral sclerosis, better known as ALS or Lou Gehrig's disease.

The story actually begins around 500 years ago, when a Portuguese immigrant to Brazil brought along an uninvited guest – a mutation in the gene for VAPB. That mutation leads to a rare form of inherited ALS that has so far been identified in about 200 people. ALS is a devastating disease that begins in middle age and affects nerves and muscles, destroying the individual's ability to move, talk, swallow and breathe, eventually killing the person who has it. There are an estimated 30,000 people with ALS in the United States alone. It affects people of all ethnicities worldwide.

While the results may not rival the artistry of glassblowers in Europe and Latin America, researchers at the National Institute of Standards and Technology (NIST) and Cornell University have found beauty in a new fabrication technique called "nanoglassblowing" that creates nanoscale (billionth of a meter) fluidic devices used to isolate and study single molecules in solution—including individual DNA strands.

Traditionally, glass micro- and nanofluidic devices are fabricated by etching tiny channels into a glass wafer with the same lithographic procedures used to manufacture circuit patterns on semiconductor computer chips. The planar (flat-edged) rectangular canals are topped with a glass cover that is annealed (heated until it bonds permanently) into place. About a year ago, the researchers observed that in some cases, the heat of the annealing furnace caused air trapped in the channel to expand the glass cover into a curved shape, much like glassblowers use heated air to add roundness to their work.

Scientists are deploying an advanced research aircraft to study a region of the atmosphere that influences climate change by affecting the amount of solar heat that reaches Earth's surface.

Findings from the project, based at the National Center for Atmospheric Research (NCAR), will be used by researchers worldwide to improve computer models of global climate in preparation for the next report by the Intergovernmental Panel on Climate Change (IPCC).

The project, running from April to June, is known as START 08 (Stratosphere-Troposphere Analyses of Regional Transport). It focuses on a remote boundary zone of the atmosphere called the tropopause, which sits at the bottom of the stratosphere. Scientists are increasingly interested in the tropopause, because of both its importance in the global climate system and because the buildup of greenhouse gases has altered this atmospheric region in ways that are not yet fully understood.

A story in the Minneapolis Star-Tribune caught my attention today, not only because it was an interesting article but because it may indicate a shift in our country’s approach to health care. As we all know, the number of people with diseases and conditions that are preventable is growing in America (and globally).

 One way to deal with this is on an individual level, treating the symptoms or curing the disease after the fact. In this model, the focus is on individual treatment, or downstream of the event. Another way to deal with this problem is at the community level, working to prevent the disease or condition from ever occurring. In this model, the focus is on prevention, or upstream of the event. (I’ve greatly oversimplified the issues – there are accidents, genetic predispositions, etc that we can’t prevent – but you get the general idea.)

Health care costs are skyrocketing, competing with gas, food and mortgages. Perhaps at an individual, day-to-day level, we can’t control gas, food or the housing crisis. But we can do something about our health. If we take steps to prevent something from occurring, we can dramatically increase the health of our nation (and ourselves) while reducing the money spent on treating health issues.

Critics may say the US is losing its competitive edge but nonetheless she remains dominant in science and technology worldwide by a large margin, according to a RAND Corporation study issued today.

The United States accounts for 40 percent of the total world's spending on scientific research and development, employs 70 percent of the world's Nobel Prize winners and is home to three-quarters of the world's top 40 universities.

An inflow of foreign students in the sciences -- as well as scientists and engineers from overseas -- has helped the United States build and maintain its worldwide lead, even as many other nations increase their spending on research and development. Continuing this flow of foreign-born talent is critical to helping the United States maintain its lead, according to the study.

Long-tailed macaques eat mostly fruit — but when resources are scarce, they’ve been known to get creative with their cuisine. When living near humans, they raid gardens and learn to beg for food. Sometimes they even steal food from inside houses.

Now, for the first time, scientists have observed long-tailed macaques fishing with their bare hands.

Nature Conservancy scientist Erik Meijaard and other researchers are the first to scientifically document this rare conduct. In a recent article published in the International Journal of Primatology, Meijaard and his coauthors say that, while conducting field studies in Indonesia, they have repeatedly observed long-tailed macaques catching fish from fast-flowing rivers.
