A code of silence in acute myeloid leukemia

2012-11-19
(Press-News.org) The development of acute myeloid leukemia (AML) is associated with a variety of genetic changes. Some of these alterations are epigenetic, wherein the sequence of the genes is unchanged, but chemical modifications to the DNA alter gene expression. In a study published in the Journal of Clinical Investigation, researchers led by Daniel Tenen at Beth Israel Deaconess Medical Center found that a transcriptional regulator known as C/EBPG was highly expressed in a subset of AML samples that had an epigenetically silenced C/EBPA gene. By blocking the epigenetic modification of C/EBPA, Tenen and colleagues found that they could reduce C/EBPG and restore normal myeloid blood cells. This study suggests that targeting the balance of C/EBPG and C/EBPA could represent a new therapeutic approach in the treatment of AML. TITLE:

New species literally spend decades on the shelf

2012-11-19
Many of the world's most unfamiliar species are just sitting around on museum shelves collecting dust. That's according to a report in the November 20th issue of the Cell Press journal Current Biology showing that it takes more than 20 years on average before a species, newly collected, will be described. It's a measure the researchers refer to as the species' "shelf life," and that long shelf life means that any conservation attempts for unknown, threatened species could come much too late. The problem, the researchers say, is due to a lack of experts and of the funding ...

No elevated 10-year risk of heart disease for people who become ill during a large E. coli outbreak

2012-11-19
According to a new study in CMAJ (Canadian Medical Association Journal), people who became ill during the Walkerton, Ontario, Escherichia coli O157:H7outbreak were not at greater risk of heart disease or stroke 10 years later. E. coli O157:H7 is a common cause of 'food poisoning." This bacterium most recently caused the outbreak involving beef from XL foods (Alberta) in September 2012, and was the major cause of illness during the large Walkerton E. coli outbreak in May 2000. In the United States, there are 63 000 infections each year, with 12 major outbreaks since 2006. ...

Toward competitive generic drug prices in Canada

2012-11-19
The commitment of Canadian premiers to lower generic drug prices is a major change in how the country prices generic drugs, and government should learn from past attempts, states an article published in CMAJ (Canadian Medical Association Journal). Generic drug prices are higher in Canada than in other industrialized countries. The authors argue that the premiers' call for a national bulk purchasing program, made earlier in 2012, is a positive step for Canadians. "The joint commitment from Canada's premiers to use coordinated bulk purchasing to lower these prices is ...

Major advance in using sunlight to produce steam without boiling water

2012-11-19
WASHINGTON, Nov. 19, 2012 — Scientists today are describing a revolutionary new way to use sunlight to produce steam and other vapors without heating an entire container of fluid to the boiling point. The advance, reported in the American Chemical Society (ACS) journal ACS Nano, has potential applications, especially in the poverty-stricken areas of the developing world, that include inexpensive, compact devices for purification of drinking water, sterilization of medical instruments and sanitizing sewage. "This research opens up a revolutionary new application of nanoparticles ...

Does your job increase your breast cancer risk?

2012-11-19
Is there a link between the risk of breast cancer and the working environment? A study published in BioMed Central's open access journal Environmental Health provides further evidence on this previously neglected research topic, confirming that certain occupations do pose a higher risk of breast cancer than others, particularly those that expose the worker to potential carcinogens and endocrine disrupters. Breast cancer is the most frequent cancer diagnosis among women in industrialized countries, and North American rates are among the highest in the world. Endocrine-disrupting ...

Many seniors' sleep habits are similar to those of young adults, study suggests

2012-11-19
PITTSBURGH, Nov. 19, 2012 – More than half of all retired people aged 65 and over report sleeping at least 7.5 hours per night, and between the hours of 11 p.m. and 7:30 a.m., contrary to commonly held assumptions that most elderly go to bed early and have trouble sleeping through the night, according to a study by researchers at the University of Pittsburgh's Sleep and Chronobiology Center (SCC) and University Center for Social and Urban Research (UCSUR). This new study, supported by a grant from the National Institute on Aging, was conducted over five years and is among ...

Mosquitos fail at flight in heavy fog

2012-11-19
Mosquitos have the remarkable ability to fly in clear skies as well as in rain, shrugging off impacts from raindrops more than 50 times their body mass. But just like modern aircraft, mosquitos also are grounded when the fog thickens. Researchers from the Georgia Institute of Technology present their findings at the 65th meeting of the American Physical Society's (APS) Division of Fluid Dynamics, Nov. 18 - 20, in San Diego, Calif. "Raindrop and fog impacts affect mosquitoes quite differently," said Georgia Tech researcher Andrew Dickerson. "From a mosquito's perspective, ...

Invisibility cloaking to shield floating objects from waves

2012-11-19
A new approach to invisibility cloaking may one day be used at sea to shield floating objects – such as oil rigs and ships – from rough waves. Unlike most other cloaking techniques that rely on transformation optics, this one is based on the influence of the ocean floor's topography on the various "layers" of ocean water. At the American Physical Society's (APS) Division of Fluid Dynamics (DFD) meeting, being held November 18-20, 2012, in San Diego, Calif., Reza Alam, assistant professor of mechanical engineering at the University of California, Berkeley, will describe ...

Owls' ability to fly in acoustic stealth provides clues to mitigating conventional aircraft noise

2012-11-19
Owls have the uncanny ability to fly silently, relying on specialized plumage to reduce noise so they can hunt in acoustic stealth. Researchers from the University of Cambridge, England, are studying the owl's wing structure to better understand how it mitigates noise so they can apply that information to the design of conventional aircraft. They present their findings at the American Physical Society's (APS) Division of Fluid Dynamics meeting, held Nov. 18 – 20, in San Diego, Calif. "Many owl species have developed specialized plumage to effectively eliminate the aerodynamic ...

Sound bullets in water

2012-11-19
Sound waves are commonly used in applications ranging from ultrasound imaging to hyperthermia therapy, in which high temperatures are induced, for example, in tumors to destroy them. In 2010, researchers at Caltech led by Chiara Daraio, a professor of aeronautics and applied physics, developed a nonlinear acoustic lens that can focus high-amplitude pressure pulses into compact "sound bullets." In that initial work, the scientists demonstrated how sound bullets form in solids. Now, they have done themselves one better, creating a device that can form and control those bullets ...
