Sea slug provides new way of analyzing brain data

Science Daily - Thu, 26/03/2015 - 5:07pm
Scientists say our brains may not be as complicated as we once thought -- and they're using sea slugs to prove it. “This research introduces new methods for pulling apart neural circuits to expose their inner building blocks. Our methods could be used to help understand how brain networks change in disease states and how drugs act to restore normal brain function,” authors say.

The Internet of Making Things

Wired News - Thu, 26/03/2015 - 5:06pm

Smart, Internet-connected “things” are showing up everywhere, changing our interactions with friends, family, colleagues, and nearly every aspect of the physical world. Internet of Things (IoT) discussions often center on the home, where your refrigerator communicates with your phone reminding you to buy milk when the carton is nearly – but not completely – empty; […]

What Makes the Perfect Gaming Mouse?

Slashdot - Thu, 26/03/2015 - 5:00pm
An anonymous reader writes A new article looks at the advanced technology that goes into many gaming mice favoured by professional gamers, from dedicated processors to custom weights for the sake of ergonomics, discussing the developments with designers at three top peripheral companies: Logitech, Razer and SteelSeries. Surprisingly, some factors that were once thought to have reached the limit of their usefulness, such as DPI sensitivity, are becoming more important again as screens get bigger and we make the move to 4K resolution. ... "With the rise of higher resolution screens, especially looking into 4K multi monitor systems and beyond, DPI might become an important factor in the future again, so we are not ruling out changes in the maximum tracking rate," says Razer CEO Min-Liang Tan.

Many Password Strength Meters Are Downright Weak, Researchers Say

Slashdot - Thu, 26/03/2015 - 4:21pm
alphadogg writes "Website password strength meters often tell you only what you want to hear rather than what you need to hear. That's the finding from researchers at Concordia University in Montreal, who examined the usefulness of those ubiquitous red-yellow-green password strength testers on websites run by big names such as Google, Yahoo, Twitter and Microsoft/Skype. The researchers used algorithms to send millions of 'not-so-good' passwords through these meters, as well as through the meters of password management services such as LastPass and 1Password, and were largely underwhelmed by what they termed wildly inconsistent results. Inconsistent can go both directions: I've seen password-strength meters that balked at absolutely everything (accepting weak passwords as good, after calling wildly long and random ones poor).

A new jumping spider with mating plug discovered from the 'Western Ghats'

Science Daily - Thu, 26/03/2015 - 4:20pm
Researchers have discovered a new species of jumping spider from 'Western Ghats' in southern India, one of the biodiversity hotspots of the world. The spider, which has been named as Stenaelurillus albus, is remarkable for the presence of mating plugs or copulatory plugs, which are supposed to function as paternity protection devices.

Fitness level associated with lower risk of some cancers, death in men

Science Daily - Thu, 26/03/2015 - 4:20pm
Men with a high fitness level in midlife appear to be at lower risk for lung and colorectal cancer, but not prostate cancer, and that higher fitness level also may put them at lower risk of death if they are diagnosed with cancer when they're older, according to a study.

Novel nanoparticle therapy promotes wound healing

Science Daily - Thu, 26/03/2015 - 4:19pm
An experimental therapy successfully tested in mice cut in half the time it takes to heal wounds compared to no treatment at all. "We envision that our nanoparticle therapy could be used to speed the healing of all sorts of wounds, including everyday cuts and burns, surgical incisions, and chronic skin ulcers, which are a particular problem in the elderly and people with diabetes," said a study co-leader.

Testosterone needs estrogen's help to inhibit depression

Science Daily - Thu, 26/03/2015 - 4:19pm
In popular culture, the phrase "battle of the sexes" seems to pit the male hormone (testosterone) against the female (estrogen). Now a researcher has documented a way in which the two hormones work together to protect low-testosterone males from the effects of anxiety and depression.

Facebook Sued For Alleged Theft of Data Center Design

Slashdot - Thu, 26/03/2015 - 3:39pm
itwbennett writes British engineering company BladeRoom Group says it contacted Facebook in 2011 about using its technique, which involves constructing data centers in a modular fashion from pre-fabricated parts. What happened next isn't clear, since much of the public version of BRG's lawsuit is redacted. But it claims Facebook ended up stealing its ideas and using them to build part of a data center in Lulea, Sweden, that opened last year. 'Facebook's misdeeds might never have come to light had it decided that simply stealing BRG's intellectual property was enough,' the company said in its lawsuit, filed Monday at the federal district court in San Jose, California. "Instead, Facebook went further when it decided to encourage and induce others to use BRG's intellectual property though an initiative created by Facebook called the 'Open Compute Project.'"

Increased sensitivity to climate change in disturbed ecosystems

Science Daily - Thu, 26/03/2015 - 3:24pm
Undisturbed ecosystems can be resistant to changing climatic conditions, but this resistance is reduced when ecosystems are subject to natural or anthropogenic disturbances. Plants are particularly sensitive to climatic changes in early life stages and even small climatic changes can cause vegetation shifts when ecosystems are disturbed by fires, insect outbreaks or other disturbances.
