New Haven, Conn. — A person's mere presence in a room can add 37 million bacteria to the air every hour — material largely left behind by previous occupants and stirred up from the floor — according to new research by Yale University engineers. "We live in this microbial soup, and a big ingredient is our own microorganisms," said Jordan Peccia, associate professor of environmental engineering at Yale and the principal investigator of a study recently published online in the journal Indoor Air. "Mostly people are re-suspending what's been deposited before. The floor dust ...

Are diet sodas good or bad for you? The jury is still out, but a new study sheds light on the impact that zero-calorie beverages may have on health, especially in the context of a person's overall dietary habits. For the average person, the scientific evidence can seem confusing. A number of studies have implicated diet beverage consumption as a cause of cardiovascular disease. However, others have suggested such drinks may be a viable tactic for people who are trying to lose or control their weight. Either way, most previous research has tended to focus either on ...

Scientists at the Gladstone Institutes have discovered a key protein that regulates insulin resistance—the diminished ability of cells to respond to the action of insulin and which sets the stage for the development of the most common form of diabetes. This breakthrough points to a new way to potentially treat or forestall type 2 diabetes, a rapidly growing global health problem. In a paper being published online this week in the Proceedings of the National Academy of Sciences, researchers in the laboratory of Gladstone Investigator Katerina Akassoglou, PhD, describe ...

WASHINGTON, DC, March 26, 2012 — While trust in science remained stable among people who self-identified as moderates and liberals in the United States between 1974 and 2010, trust in science fell among self-identified conservatives by more than 25 percent during the same period, according to new research from Gordon Gauchat, a postdoctoral fellow at the University of North Carolina-Chapel Hill's Cecil G. Sheps Center for Health Services Research. "You can see this distrust in science among conservatives reflected in the current Republican primary campaign," said Gauchat, ...

Dispatchers who answer 911 and 999 emergency calls suffer emotional distress which can lead to symptoms of Post-Traumatic Stress Disorder (PTSD), a new study reports. The research, published in the Journal of Traumatic Stress, reveals that direct exposure to traumatic events is not necessary to lead to post-trauma disorders. The research was conducted by Dr Michelle Lilly from Northern Illinois University and researcher Heather Pierce, a former 911 dispatcher. "Post-Traumatic psychological disorders are usually associated with front line emergency workers, such as police ...

Scientists at the University of Guelph have found a way to successfully clone American elm trees that have survived repeated epidemics of their biggest killer — Dutch elm disease. The breakthrough, published today in the Canadian Journal of Forest Research, is the first known use of in vitro culture technology to clone buds of mature American elm trees. "This research has the potential to bring back the beloved American elm population to North America," said Prof. Praveen Saxena, a plant scientist who worked on the project with Professor Alan Sullivan. Both are from ...

Researchers at the University of British Columbia have identified a number of tiny but powerful "genetic regulators" that are hijacked by avian and swine flu viruses during human infection. The discovery, published this week in the Journal of Virology, could reveal new targets for broad-spectrum antivirals to combat current – and perhaps future – strains of influenza A viruses. The study is the first to compare the role played by human microRNAs – small molecules that control the expression of multiple genes – in the life cycle of two viruses of continued concern to ...

Bottlenose dolphins in Barataria Bay, Louisiana, are showing signs of severe ill health, according to NOAA marine mammal biologists and their local, state, federal and other research partners. Barataria Bay, located in the northern Gulf of Mexico, received heavy and prolonged exposure to oil during the Deepwater Horizon oil spill. Based on comprehensive physicals of 32 live dolphins from Barataria Bay in the summer of 2011, preliminary results show that many of the dolphins in the study are underweight, anemic, have low blood sugar and/or some symptoms of liver and ...

Queen's University professor Selim Akl has provided additional proof to the theory that nature computes. Dr. Akl (School of Computing) placed rolled oats on a map of Canada, covering the major urban areas. One urban area held the slime mold. The slime mold reached out for the food, creating thin tubes that eventually formed a network mirroring the Canadian highway system. "By showing species as low as slime mold can compute a network as complex as the Canadian highway system, we were able to provide some evidence that nature computes," says Dr. Akl. Moving forward, Dr. ...

A breakthrough using cutting-edge stem cell research could speed up the discovery of new treatments for motor neurone disease (MND). The international research team has created motor neurones using skin cells from a patient with an inherited form of MND. The study discovered that abnormalities of a protein called TDP-43, implicated in more than 90 per cent of cases of MND, resulted in the death of motor neurone cells. This is the first time that scientists have been able to see the direct effect of abnormal TDP-43 on human motor neurons. The study, led by the ...

The national recession didn't just hit people living in the U.S. – it's made it more difficult for people to pay for medical bills in poor countries like Honduras, according to a new University of Michigan study. As employment opportunities have dried up for Latino immigrants in the U.S., so has their ability to send financial assistance to chronically ill family members in their home countries, according to a U-M study published online this week ahead of print in the International Journal of Health Services. "Remittance payments from relatives living in the United ...

Bethesda, Md. -- Late gestation is a busy time for babies getting ready for life outside the womb, particularly for functions critical to life such as breathing and maintaining an adequate heartbeat. These two functions are connected in mature infants and healthy people throughout life, so measuring their level of connectedness can give doctors a cue about whether an infant is ready to head home or needs to remain in the care of the neonatal intensive care unit (NICU). Current methods to analyze this connection are not yet fully developed, leaving doctors and nurses without ...

Researchers have devised a nanoscale sensor to electronically read the sequence of a single DNA molecule, a technique that is fast and inexpensive and could make DNA sequencing widely available. The technique could lead to affordable personalized medicine, potentially revealing predispositions for afflictions such as cancer, diabetes or addiction. "There is a clear path to a workable, easily produced sequencing platform," said Jens Gundlach, a University of Washington physics professor who leads the research team. "We augmented a protein nanopore we developed for ...

VIDEO: This shows a simulation of wind turbine performance. Click here for more information. The production of wind-derived renewable energy is growing, and so, it's important to help wind farm owners operate at higher efficiencies with lower costs. In fact, figures from the World Wind Energy Association report that installed global capacity for wind-energy production was approximately 240,000 megawatts of power in 2011, up nearly ten fold since 2001. That growth, which ...

EAST LANSING, Mich. — The huge changes in the Earth's crust that influenced human evolution are being redefined, according to research published today in Nature Geoscience. The Great Rift Valley of East Africa – the birthplace of the human species – may have taken much longer to develop than previously believed. ""We now believe that the western portion of the rift formed about 25 million years ago, and is approximately as old as the eastern part, instead of much younger as other studies have maintained," said Michael Gottfried, Michigan State University associate professor ...

Developing a drug or vaccine requires a delicate balancing act with the immune system. On one hand, medications need to escape detection by the immune system in order to perform their function. But vaccinations — de-activated versions of a disease or virus — need to do the reverse. They prompt the immune system to create protective antibodies. But scientists are still stumped by how the immune system recognizes different particles, and how it chooses whether or not to react against them. Using nanoparticles made of pure gold, Dr. Dan Peer, head of Tel Aviv University's ...

Advances in chemotherapy have dramatically improved the outlook for many cancer patients, but the side effects of this treatment are daunting.

WEST LAFAYETTE, Ind. - A Purdue University food scientist has developed a way to encase nutritional supplements in food-based products so that one day consumers might be able to sprinkle vitamins, antioxidants and other beneficial compounds right onto their meals. Srinivas Janaswamy, a research assistant professor of food science, said many of the nutraceuticals, or nutritional supplements, added to foods today are not structurally stable. Heat, light, oxygen and other external factors could degrade the supplements, rendering them ineffective. "There are many methods ...

Scientists recently concluded an expedition aboard the research vessel JOIDES Resolution to learn more about Atlantis Massif, an undersea mountain, or seamount, that formed in a very different way than the majority of the seafloor in the oceans. Unlike volcanic seamounts, which are made of the basalt that's typical of most of the seafloor, Atlantis Massif includes rock types that are usually only found much deeper in the ocean crust, such as gabbro and peridotite. The expedition, known as Integrated Ocean Drilling Program (IODP) Expedition 340T, marks the first time ...

While most American's knew Red Skelton for his starring rolls on radio, in movies and his own television variety show where he was known as the king of comedy and adlibs, few people knew he was pursuing another talent. Red Skelton started dabbling in painting as a way to relax and unwind. Years of producing a weekly variety show brings great pressure to create new material and routines. The work load can be overwhelming. Everyone needs a way to relax and the creative side of Red was always working overtime. His wife Georgia, having some experience in the arts, suggested ...
