Winning the war against Human parainfluenza virus

Science Daily - Mon, 20/10/2014 - 2:50pm
Researchers have moved a step closer to identifying a treatment for the dreaded Human parainfluenza virus. These highly-infectious viruses are the leading cause of upper and lower respiratory tract disease in young children, including Croup, responsible for thousands of hospitalizations in the developed world, and hundreds of thousands of deaths each year in developing countries.

New antidepressant: Rapid agent restores pleasure-seeking ahead of other antidepressant action

Science Daily - Mon, 20/10/2014 - 2:50pm
A drug being studied as a fast-acting mood-lifter restored pleasure-seeking behavior independent of -- and ahead of -- its other antidepressant effects. Within 40 minutes after a single infusion of ketamine, treatment-resistant depressed bipolar disorder patients experienced a reversal of a key symptom -- loss of interest in pleasurable activities -- which lasted up to 14 days. Brain scans traced the agent's action to boosted activity in areas at the front and deep in the right hemisphere of the brain.

Digital native fallacy: Teachers still know better when it comes to using technology

Science Daily - Mon, 20/10/2014 - 2:49pm
A new study looks at how teachers and students use technology inside and outside the classroom. It turns out that members of today's younger Net Generation aren't more tech savvy than their teachers just because they were born into a world full of computers. In fact, if it weren't for the coaxing and support of their educators, many students would never use their electronic devices for more than playing games or listening to music, say experts.

Design of micro, nanoparticles to improve treatments for Alzheimer's, Parkinson's

Science Daily - Mon, 20/10/2014 - 2:49pm
Techniques are being developed to deliver correctly and effectively certain drugs to treat Alzheimer's and Parkinson's. Both disorders affect the neurones: their structure and function is lost, and this in turn leads to the deterioration in the patient's motor, cognitive, sensory and emotional functions.

New class of drugs shows promise in treating chronic diarrhea

Science Daily - Mon, 20/10/2014 - 2:49pm
A pilot study testing a new type of drug in patients with chronic diarrhea has shown promising effects on reducing their symptoms. Bile acid diarrhea (BAD) is a common cause of chronic diarrhea that is estimated to affect one in 100 adults in western countries, but is often mistaken for irritable bowel syndrome (IBS) by doctors. Many patients are not diagnosed correctly and undergo repeated unnecessary tests.

Cold sores increase risk of dementia, research suggests

Science Daily - Mon, 20/10/2014 - 2:49pm
Infection with herpes simplex virus increases the risk of Alzheimer's disease, researchers claim. "Our results clearly show that there is a link between infections of herpes simplex virus and the risk of developing Alzheimer's disease. This also means that we have new opportunities to develop treatment forms to stop the disease," says one of the researchers behind the study.

Earthquakes in the ocean: Towards a better understanding of their precursors

Science Daily - Mon, 20/10/2014 - 2:49pm
New research offers the first theoretical model that, based on fluid-related processes, explains the seismic precursors of an underwater earthquake. Using quantitative measurements, this innovative model established a link between observed precursors and the mainshock of an earthquake. The results open a promising avenue of research for guiding future investigations on detecting earthquakes before they strike.

Goldilocks principle wrong for particle assembly: Too hot and too cold is just right

Science Daily - Mon, 20/10/2014 - 2:47pm
Microscopic particles that bind under low temperatures will melt as temperatures rise to moderate levels, but re-connect under hotter conditions, a team of scientists has found. Their discovery points to new ways to create “smart materials,” cutting-edge materials that adapt to their environment by taking new forms, and to sharpen the detail of 3D printing.

Advances in creating treatment for common childhood blood cancer

Science Daily - Mon, 20/10/2014 - 2:47pm
A new drug in development may offer first alternative to standard chemotherapy for T-Cell Acute Lymphoblastic Leukemia, scientists report. An estimated quarter of the 500 U.S. adolescents and young adults diagnosed each year with this aggressive disease fail to respond to standard chemotherapy drugs that target cancer cells.

Origins of sex discovered: Side-by-side copulation in distant ancestors

Science Daily - Mon, 20/10/2014 - 2:38pm
A palaeontologist has revealed how the intimate act of sexual intercourse first evolved in our deep distant ancestors. In one of the biggest discoveries in the evolutionary history of sexual reproduction, scientists have found that internal fertilization and copulation appeared in ancient armored fishes, called placoderms, about 385 million years ago in what is now Scotland.

Ubuntu Turns 10

Slashdot - Mon, 20/10/2014 - 2:10pm
Scott James Remnant, now Technical Lead on ChromeOS, was a Debian developer before that. That's how he became involved from the beginning (becoming Developer Manager, and then serving on the Technical Board) on the little derivative distribution that Mark Shuttleworth decided to make of Debian Unstable, and for which the name Ubuntu was eventually chosen. On this date in 2004, Ubuntu 4.10 -- aka Warty Warthog, or just Warty -- was released, and Remnant has shared a detailed, nostalgic look back at the early days of the project that has (whatever else you think of it ) become one of the most influential in the world of open source and Free software. I was excited that Canonical sent out disks that I could pass around to friends and family that looked acceptably polished to them in a way that Sharpie-marked Knoppix CD-ROMs didn't, and that the polish extended to the installer, the desktop, and the included constellation of software, too.

Microsoft Gearing Up To Release a Smartwatch of Its Own

Slashdot - Mon, 20/10/2014 - 1:29pm
SmartAboutThings writes The smartwatch market is still in its nascent form, but with Apple releasing its AppleWatch in early 2015, things are going to change. And Microsoft wants to make sure it's not late to the party, as it has been so many times in the past. That's why it plans on releasing its own smartwatch, which would be the first new category under CEO Nadella. The device could get launched with two specific features that could make it stand apart from other similar devices — much better battery life and cross-platform support for iOS and Android users. A release before this year's holiday season is in the cards, with no details on the pricing nor availability. (Also at Reuters and The Inquirer.)

Head injury causes immune system to attack brain, new study finds

Science Daily - Mon, 20/10/2014 - 1:04pm
Scientists have uncovered a surprising way to reduce the brain damage caused by head injuries -- stopping the body's immune system from killing brain cells. A new study showed that in experiments on mice, an immune-based treatment reduced the size of brain lesions. The authors suggest that if the findings apply to humans, this could help prevent brain damage from accidents, and protect players of contact sports like football, rugby and boxing.
