Clinical trial could change standard treatment for stroke

Science Daily - 8 hours 52 min ago
A large international clinical trial has shed new light on the effectiveness of current hospital protocols for managing blood pressure in stroke patients. The study has tried to solve two major conundrums faced by doctors when treating people who have suffered a stroke -- should blood pressure be lowered using medicated skin patches, and should existing blood pressure medication be stopped or continued after a stroke?

Startup Aims to Remake Computer Security for the Cloud Age

Wired News - 9 hours 22 min ago

Steve Herrod was there for the rise of Nicira, the Silicon Valley startup that reinvented the way we build computer networks and then sold itself to tech giant VMware for $1.26 billion. He was VMware’s chief technology officer at the time, one of the driving forces behind this massive deal, and after leaving VMware for […]

Hungary To Tax Internet Traffic

Slashdot - 9 hours 25 min ago
An anonymous reader writes: The Hungarian government has announced a new tax on internet traffic: 150 HUF ($0.62 USD) per gigabyte. In Hungary, a monthly internet subscription costs around 4,000-10,000 HUF ($17-$41), so it could really put a constraint on different service providers, especially for streaming media. This kind of tax could set back the country's technological development by some 20 years — to the pre-internet age. As a side note, the Hungarian government's budget is running at a serious deficit. The internet tax is officially expected to bring in about 20 billion HUF in income, though a quick look at the BIX (Budapest Internet Exchange) and a bit of math suggests a better estimate of the income would probably be an order of magnitude higher.

New window on the early Universe

Science Daily - 9 hours 39 min ago
Scientists see good times approaching for astrophysicists after hatching a new observational strategy to distill detailed information from  galaxies at the edge of the Universe. Using two world-class supercomputers, the researchers were able to demonstrate the effectiveness of their approach by simulating the formation of a massive galaxy at the dawn of cosmic time. The ALMA radio telescope – which stands at an elevation of 5,000 meters in the Atacama Desert of Chile, one of the driest places on earth – was then used to forge observations of the galaxy, showing how their method improves upon previous efforts.

Susceptibility for relapsing major depressive disorder can be calculated

Science Daily - 9 hours 39 min ago
The question if an individual will suffer from relapsing major depressive disorder is not determined by accident. Neuroscientists have chosen a new research approach, using computer-based models to study the disease. They show that chronic depression is triggered due to an unfortunate combination of internal and external factors.

Cause of aging remains elusive, researchers assert

Science Daily - 9 hours 39 min ago
A report by Chinese researchers a few months ago was a small sensation: they appeared to have found the cause for why organisms age. Another international team of scientists has now refuted a basic assumption of the article. The reasons for aging thus remain elusive, they say.

Assessing safety of masks: Efficacy of anti-particle filters under examination

Science Daily - 9 hours 39 min ago
Researchers have developed a method to assess the efficacy of anti-particle filters and masks. This method will help to decide the most suitable system depending on the professional activity. Thanks to the development of a simulation model for the breathing process of a person in a dusty work environment, researchers have designed a method capable to experimentally determine the efficacy of a series of existing filters and masks in the market.

Protecting us from our cells: Research could speed trials to treat auto-immune diseases

Science Daily - 9 hours 39 min ago
Our immune system defends us from harmful bacteria and viruses, but, if left unchecked, the cells that destroy those invaders can turn on the body itself, causing auto-immune diseases like type-1 diabetes or multiple sclerosis. A molecule called insulin-like growth factor-1 (IGF-1) boosts the body’s natural defense against this ‘friendly fire’, scientists have found. The findings are especially exciting because IGF-1 is already approved for use in patients, which could speed up the move to clinical trials for treating auto-immune diseases.

Genes exhibit different behaviours in different stages of development

Science Daily - 9 hours 39 min ago
The effect that genes have on our brain depends on our age, researchers say. It has been known for a number of years that particular genetic variations are of importance for the functioning of neural circuits in the brain. Just how these effects differ in the various stages of life has until recently not been fully understood. This international study has been able to demonstrate that genetic variations at different times in our lives can actually have opposite effects on the brain, which provides an explanation for the differences that clinicians observe in the psychiatric symptoms and response to medications of adolescents and adults.

Xerox Alto Source Code Released To Public

Slashdot - 10 hours 7 min ago
zonker writes: In 1970, the Xerox Corporation established the Palo Alto Research Center (PARC) with the goal to develop an "architecture of information" and lay the groundwork for future electronic office products. The pioneering Alto project that began in 1972 invented or refined many of the fundamental hardware and software ideas upon which our modern devices are based, including raster displays, mouse pointing devices, direct-manipulation user interfaces, windows and menus, the first WYSIWYG word processor, and Ethernet. The first Altos were built as research prototypes. By the fall of 1976 PARC's research was far enough along that a Xerox product group started to design products based on their prototypes. Ultimately, ~1,500 were built and deployed throughout the Xerox Corporation, as well as at universities and other sites. The Alto was never sold as a product but its legacy served as inspiration for the future. With the permission of the Palo Alto Research Center, the Computer History Museum is pleased to make available, for non-commercial use only, snapshots of Alto source code, executables, documentation, font files, and other files from 1975 to 1987. The files are organized by the original server on which they resided at PARC that correspond to files that were restored from archive tapes. An interesting look at retro-future.
