3:45 PM | Futile ICU Care Prevents Other Patients From Getting Treatment
In a bygone era, doctors thought every life was important. Treatment was aggressive and persistent in intensive care units even when it might be futile.  In the 21st century world, resources are the first consideration, and there are plenty of ideas about ways to curb treatment and lower costs. A new analysis finds that doctors could try a little less in the intensive care unit - because otherwise they are causing other ill patients needing medical attention to wait for critical care […]

3:30 PM | Record Decline Of Ice Sheets, Except East Antarctica
For the first time, scientists have mapped elevation changes of Greenlandic and Antarctic glaciers. For the new digital maps, the researchers evaluated all data by the CryoSat-2 altimeter SIRAL. Satellite altimeter measure the height of an ice sheet by sending radar or laser pulses in the direction of the earth. These signals are then reflected by the surface of the glaciers or the surrounding waters and are subsequently retrieved by the satellite. This way the scientists were able to precisely […]

3:00 PM | Low-Tech: Security Flaws In Airport Backscatter X-Ray Scanners
There are several security vulnerabilities in full-body backscatter X-ray scanners deployed to U.S. airports between 2009 and 2013. In laboratory tests, researchers were able to successfully conceal firearms and plastic explosive simulants from the Rapiscan Secure 1000 scanner. The team was also able to modify the scanner operating software so it presents an "all-clear" image to the operator even when contraband was detected. "Frankly, we were shocked by what we found," said J. Alex Halderman, […]

2:24 PM | No Radiation: Using Ions To Test The Shelf-Life Of Nuclear Reactors
The structural components of advanced reactors such as the sodium fast reactor and the traveling wave nuclear reactor must be able to withstand the extreme levels of radioactivity from the fission reaction itself, at temperatures well above 400 Celsius. Standard tests of such components are expensive, require increasingly rare test reactors and test periods that are impractical. In addition, the samples themselves also become radioactive making subsequent studies and examination time consuming […]

1:56 PM | Where The River Meets The Sea, Renewable Energy Happens
Where the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to a team of mechanical engineers at MIT who evaluated the method of power generation called pressure retarded osmosis (PRO), in which two streams of different salinity are mixed to produce energy. A pressure retarded osmosis system of this kind takes in river water and seawater on either side of a semi-permeable membrane. Through osmosis, water from the less-salty stream would […]

1:31 PM | Monsoon Season Affects Methane Emissions
Changes in the Asian monsoon have affected emissions of methane from the Tibetan Plateau over the last 6,000 years, finds a new paper.The concentration of methane in the atmosphere has more than doubled over the past century, though it is very short lived compared to carbon dioxide and hasn't been considered much of a factor in climate change. Factors in methane levels include leaks from gas wells, increased rice cultivation and ruminant animals in the dairy and meat industry. It could also be […]

1:31 PM | Transparent Concentrator: Solar Energy That Won't Block Your View
Researchers have developed a way to use windows for solar energy - without ruining your view. The new technology is a solar concentrator, called a transparent luminescent solar concentrator, that is placed over the window and creates solar energy while still allowing people to see through it. The Michigan State University researchers say it can also be used on buildings, cell phones or any other device that has a flat, clear surface. Attempts to create solar cells with luminescent plastic-like […]

12:30 PM | Indication Of Considerable Added Benefit Using Ruxolitinib For Myelofibrosis
Ruxolitinib (trade name: Jakavi) has been approved since August 2012 for the treatment of adults with myelofibrosis. Myelofibrosis is a rare disease of the bone marrow, in which the bone marrow is replaced by connective tissue. As a consequence of this so-called fibrosis, the bone marrow is no longer able to produce enough blood cells. Sometimes the spleen or the liver takes over some of the blood production.  Then these organs enlarge and can cause abdominal discomfort and pain. The […]

11:00 AM | Sociologists Link Breastfeeding To Lower Risk Of Postnatal Depression
Survey results of over 10,000 mothers have led sociologists to conclude that women who breastfed their babies are at significantly lower risk of postnatal depression than those who do not.The paper in Maternal and Child Health notes that mothers who planned to breastfeed and who actually went on to breastfeed were around 50% less likely to become depressed than mothers who had not planned to, and who did not, breastfeed. Mothers who planned to breastfeed, but who did not go on to breastfeed, […]
