Experimental drug treatment for Rett syndrome suggests disorder is reversible, mouse study shows

Science Daily - Mon, 27/07/2015 - 10:02pm
A strikingly new approach for treating Rett syndrome has been developed by scientists, a devastating autism spectrum disorder. In their report, the researchers demonstrate that treatment with small-molecule drug candidates significantly extends lifespan in male mice that model Rett and ameliorates several behavioral symptoms in females.

Flow means 'go' for proper lymph system development

Science Daily - Mon, 27/07/2015 - 10:02pm
The lymph system provides a slow flow of fluid from tissues into the blood. It returns fluid and proteins that leak from blood vessels, provides passage for immune cells from the tissues to the blood, and hosts key niches for immune cells. How this system develops hasn't been well understood, but now researchers have found from that the early flow of lymph fluid is a critical factor in the development of mature lymphatic vessels.

AI and robotics researchers call for global ban on autonomous weapons

Kurzweil AI - Mon, 27/07/2015 - 9:48pm

More than 1,000 leading artificial intelligence (AI) and robotics researchers and others, including Stephen Hawking and Elon Musk, just signed and published an open letter from the Future of Life Institute (FLI) today calling for a ban on offensive autonomous weapons.

FLI defines “autonomous weapons” as those that select and engage targets without human intervention, such as armed quadcopters that can search for and eliminate people meeting certain pre-defined criteria, but do not include cruise missiles or remotely piloted drones for which humans make all targeting decisions.

The researchers believe that AI technology has reached a point where the deployment of such systems is feasible within years, not decades, and that the stakes are high: autonomous weapons have been described as the third revolution in warfare, after gunpowder and nuclear arms.

Only be a matter of time until they appear on the black market

“If any major military power pushes ahead with AI weapon development, a global arms race is virtually inevitable, and the endpoint of this technological trajectory is obvious: autonomous weapons will become the Kalashnikovs of tomorrow. Unlike nuclear weapons, they require no costly or hard-to-obtain raw materials, so they will become ubiquitous and cheap for all significant military powers to mass-produce.

“It will only be a matter of time until they appear on the black market and in the hands of terrorists, dictators wishing to better control their populace, warlords wishing to perpetrate ethnic cleansing, etc. Autonomous weapons are ideal for tasks such as assassinations, destabilizing nations, subduing populations and selectively killing a particular ethnic group. We therefore believe that a military AI arms race would not be beneficial for humanity.”

The proposed ban is similar to the broadly supported international agreements that have successfully prohibited chemical, biological weapons, blinding laser weapons, and space-based nuclear weapons.

“We believe that AI has great potential to benefit humanity in many ways, and that the goal of the field should be to do so. Starting a military AI arms race is a bad idea, and should be prevented by a ban on offensive autonomous weapons beyond meaningful human control,” the letter concludes.

German Scientists Confirm NASA's Controversial EM Drive

Slashdot - Mon, 27/07/2015 - 9:28pm
MarkWhittington writes: Hacked Magazine reported that a group of German scientists believe that they have confirmed that the EM Drive, the propulsion device that uses microwaves rather than rocket fuel, provides thrust. The experimental results are being presented at the American Institute for Aeronautics and Astronautics' Propulsion and Energy Forum in Orlando by Martin Tajmar, a professor and chair for Space Systems at the Dresden University of Technology. Tajmar has an interest in exotic propulsion methods, including one concept using "negative matter."

You3dit is Working to Help Crowdsource 3D Design and Printing (Video)

Slashdot - Mon, 27/07/2015 - 8:44pm
The example you3dit (You 3D It) person Chris McCoy uses in this video is a prosthetic hand they wanted to make because one of their people lost fingers in a construction accident. Instead of drawing up plans for a new hand, they searched online -- and found enablingthefuture.org, which is all about making 3-D printed prosthetic hands. Using a predesigned hand was obviously much simpler than starting from scratch, and was totally in line with the Open Source "Why reinvent the wheel?" philosophy. So you3dit helps make 3-D printed items of one sort or another, and can either print them for you at their place or help you find someone local to help with the printing, assuming you can't do it yourself. As you might expect, they did a Kickstarter project. It was for a product called Raver Rings. Unlike many Kickstarter projects we mention on Slashdot, this one didn't fly. In fact, it only got $2,275 in pledges against a $10,000 goal. No matter. There are many other useful things the you3dit community can make -- or help you make -- without Kickstarter.

Computer Science Enrollments Match NASDAQ's Rises and Fall

Slashdot - Mon, 27/07/2015 - 8:00pm
dcblogs writes: In March 2000, the NASDAQ composite index reached a historic high of 5,048, at just about the same time undergrad computer science enrollments hit a peak of nearly 24,000 students at PhD-granting institutions in the U.S. and Canada, according to data collected by the Computing Research Association in its most recent annual Taulbee Survey. By 2005, computer science enrollments had halved, declining to just over 12,000. On July 17, the NASDAQ hit its highest point since 2000, reaching a composite index of 5,210. In 2014, computer science undergrad enrollments reached nearly, 24,000, almost equal to the 2000 high. Remarkably, it has taken nearly 15 years to reach the earlier enrollment peak.

One in four patients with defibrillators experiences boost in heart function over time

Science Daily - Mon, 27/07/2015 - 7:38pm
A study of outcomes among 1,200 people with implanted defibrillators — devices intended to prevent sudden cardiac death from abnormal heart rhythms — shows that within a few years of implantation, one in four experienced improvements in heart function substantial enough to put them over the clinical threshold that qualified them to get a defibrillator in the first place. A report on the study reveals these patients had markedly lower risk of dying and were far less likely to suffer arrhythmia-terminating device shocks, suggesting their hearts had grown less prone to developing lethal rhythms.

Mobile stroke treatment units may greatly improve survival rates, chance of recovery for ischemic stroke patients

Science Daily - Mon, 27/07/2015 - 7:37pm
Mobile Stroke Treatment Units (MSTUs) can significantly reduce the time it takes to diagnose and treat patients for stroke, new research confirms. MSTUs resemble ambulances on the outside, but contain highly specialized staff, equipment and medications strictly used for diagnosing and treating strokes. Specifically, they are equipped with diagnostic tools and telemedicine capabilities that facilitate real-time communication with hospital-based stroke specialists, enabling immediate diagnosis and the administration of IV tPA for eligible patients while en route to the hospital.

A new technique that could help surgeons more precisely define the locations of pituitary tumors in near real-time has been demonstrated by a team of scientists. The new strategy uses a visualization technique (matrix-assisted laser desorption/ionization mass spectrometry imaging -- MALDI MSI) that can analyze specific hormones, including growth hormone and prolactin, in tissue.
