RF heating of magnetic nanoparticles improves thawing of cryopreserved biomaterials

Science Daily - Thu, 23/10/2014 - 2:07pm
Successful techniques for cryopreserving bulk biomaterials and organ systems would transform current approaches to transplantation and regenerative medicine. However, while vitrified cryopreservation holds great promise, practical application has been limited to smaller systems (cells and thin tissues) due to diffusive heat and mass transfer limitations, which are typically manifested as devitrification and cracking failures during thaw. Reserachers leverage a clinically proven technology platform, in magnetically heated nanoparticles, to overcome this major hurdle limiting further advancement in the field of cryopreservation.

Acousto-optic tunable filter technology for balloon-borne platforms

Science Daily - Thu, 23/10/2014 - 2:07pm
A balloon-borne acousto-optic tunable filter hyperspectral imager is ideally suited to address numerous outstanding questions in planetary science. Their spectral agility, narrowband wavelength selection, tolerance to the near-space environment, and spectral coverage would enable investigations not feasible from the ground. Example use cases include synoptic observations of clouds on Venus and the giant planets, studies of molecular emissions from cometary comae, the mapping of surface ices on small bodies, and polarimetry.

Retaining forests where raptors nest can help to protect biodiversity

Science Daily - Thu, 23/10/2014 - 2:07pm
Raptors can affect the distribution of other species and they can also be used to find forests with high biodiversity value, researchers say. Predators influence decisions on conservation actions because they awake a remarkable interest in the society. However, favoring just predators in conservation can also mislead the scarce funding invested in nature conservation.

No-till agriculture may not bring hoped-for boost in global crop yields, study finds

Science Daily - Thu, 23/10/2014 - 2:07pm
No-till farming appears to hold promise for boosting crop yields only in dry regions, not in the cool, moist areas of the world, this study found. As the core principle of conservation agriculture, no-till has been promoted worldwide in an effort to sustainably meet global food demand.

Cisco Fixes Three-Year-Old Telnet Flaw In Security Appliances

Slashdot - Thu, 23/10/2014 - 2:06pm
Trailrunner7 writes "There is a severe remote code execution vulnerability in a number of Cisco's security appliances, a bug that was first disclosed nearly three years ago. The vulnerability is in Telnet and there has been a Metasploit module available to exploit it for years. The FreeBSD Project first disclosed the vulnerability in telnet in December 2011 and it was widely publicized at the time. Recently, Glafkos Charalambous, a security researcher, discovered that the bug was still present in several of Cisco's security boxes, including the Web Security Appliance, Email Security Appliance and Content Security Management Appliance. The vulnerability is in the AsyncOS software in those appliances and affects all versions of the products." At long last, though, as the article points out, "Cisco has released a patched version of the AsyncOS software to address the vulnerability and also has recommended some workarounds for customers."

Hippos-Sussita excavation: Silent evidence of the earthquake of 363 CE

Science Daily - Thu, 23/10/2014 - 2:04pm
Silent evidence of a large earthquake in 363 CE -- the skeleton of a woman with a dove-shaped pendant -- was discovered under the tiles of a collapsed roof by archeologists from the University of Haifa during this excavation season at Hippos-Sussita. They also found a large muscular marble leg and artillery ammunition from some 2,000 years ago. "The data is finally beginning to form a clear historical-archaeological picture," said Dr. Michael Eisenberg, head of the international excavation team.

A new tune: There is intonation in sign language too

Science Daily - Thu, 23/10/2014 - 2:04pm
Intonation is an integral part of communication for all speakers. But can sign languages have intonation? A new study shows that signers use their faces to create intonational ‘melodies’ just as speakers use their voices, and that the melodies of the face can differ from one sign language to another.

Sale of IBM's Chip-Making Business To GlobalFoundries To Get US Security Review

Slashdot - Thu, 23/10/2014 - 1:25pm
dcblogs writes IBM is an officially sanctioned trusted supplier to the U.S. Defense Dept., and the transfer of its semiconductor manufacturing to GlobalFoundries, a U.S.-based firm owned by investors in Abu Dhabi, will get U.S. scrutiny. Retired U.S. Army Brig. Gen. John Adams, who authored a report last year for an industry group about U.S. supply chain vulnerabilities and national security, said regulators will have to look closely. "I don't want cast aspersions unnecessarily on Abu Dubai — but they're not Canada," said Adams "I think that the news that we may be selling part of our supply chain for semiconductors to a foreign investor is actually bad news."

Cancer patients should not hesitate to speak with their doctors about dietary supplements

Science Daily - Thu, 23/10/2014 - 1:20pm
Many cancer patients use dietary supplements such as vitamins, minerals and herbs or other botanicals but often don't tell their doctor. This gap in communication can happen when patients believe that their doctors are indifferent or negative toward their use of these supplements. As a result, patients may find information about dietary supplements from unreliable sources, exposing themselves to unneeded risks, experts say.

Recent space debris threat warded off

Science Daily - Thu, 23/10/2014 - 1:20pm
Space debris, also known as 'space junk,' is an ongoing real-life concern for teams managing satellites orbiting Earth, including NOAA-NASA's Suomi National Polar-orbiting Partnership satellite. It is not unusual for satellites that have the capability of maneuvering to be repositioned to avoid debris or to maintain the proper orbit.
