World first demo of labyrinth magnetic-domain-optical Q-switched laser

Science Daily - Wed, 27/07/2016 - 2:08pm
Researchers have fabricated the first magneto-optical (MO) Q-switched laser. Unlike electro-optic (EO) and acousto-optic (AO) effects, MO effects had not previously been used in Q-switched lasers, even though they are also very well-known phenomena. The fabricated MO Q-switched laser contributes to the development of compact high-power lasers.

LastPass Accounts Can Be 'Completely Compromised' When Users Visit Sites

Slashdot - Wed, 27/07/2016 - 2:00pm
Reader mask.of.sanity writes: A dangerous zero-day vulnerability has been found in popular cloud password vault LastPass, which can completely compromise user accounts when users visit malicious websites. The flaw is today being reported to LastPass by established Google Project zero hacker Tavis Ormandy who says he has found other "obvious critical problems". Interestingly, Mathias Karlsson, a security researcher has also independently found flaws in LastPass. In a blog post, he wrote that he was able to trick LastPass into believing he was on the real Twiter website and cough up the users' credentials of a bug in the LastPass password manager's autofill functionality. LastPass has fixed the bug, but Karlsson advises users to disable autofill functionality and use multi-factor authentication. At this point, it's not clear whether Ormandy is also talking about the same vulnerability.

Two neonicotinoid insecticides may have inadvertent contraceptive effects on male honey bees

Science Daily - Wed, 27/07/2016 - 1:07pm
Male honey bees, called drones, can be affected by two neonicotinoid insecticides by reducing male honey bee lifespan and number of living sperm. Both insecticides are currently partially banned in Europe. Now researchers are calling for more thorough environmental risk assessments of these neonicotinoids.

Saharan dust: Reliable forecasts for photovoltaic output

Science Daily - Wed, 27/07/2016 - 1:06pm
A hazy sky and dirty cars are well-known consequences of Saharan dust carried to Europe by air currents. As part of the “PerduS” project, researchers are currently examining how dust – as haze in the atmosphere and deposited on solar panels – affects the output of photovoltaic systems. The aim is to provide a more reliable forecast for the output of photovoltaic systems through a better prediction of the spread of dust.

Watering solar cells makes them grow in power

Science Daily - Wed, 27/07/2016 - 1:06pm
Perovskite solar cells are the rising star in the photovoltaic landscape. Since their invention, less than ten years ago, their efficiency has doubled twice and it is now over 22% -- an astonishing result in the renewable energy sector. Researchers have now clarified the relationship between air exposure and enhanced electric proprieties in perovskite solar cells.

New approach for environmental test on livestock drugs

Science Daily - Wed, 27/07/2016 - 1:05pm
Drugs for livestock can harm beneficial organisms that break down dung. Therefore newly developed medical substances need to be tested on single species in the lab. An international research group has been scrutinizing the reliability of such laboratory tests, evaluating the implementation of a field test based on the anti-parasitic drug ivermectin at four climatically different locations. The scientists have now presented a novel approach for more advanced environmental compatibility tests.

Discovery of biomarkers for the prognosis of chronic kidney disease

Science Daily - Wed, 27/07/2016 - 1:05pm
Currently, there is no effective method to predict the prognosis of chronic kidney disease (CKD) patients. Researchers have now found that measuring D-amino acids, which present only trace in human, provides prognostic information of CKD. The present discovery would facilitate CKD treatment and thus improve the prognosis of CKD, and may also lead to the further discovery of novel therapy. The potential application is not limited to kidney diseases: the disease context ranges to life style-related diseases such as diabetes mellitus and hypertension, as well as lethal diseases including cardiovascular diseases, say the investigators.

Treating pain without feeding addiction: Study shows promise of non-drug pain management

Science Daily - Wed, 27/07/2016 - 1:04pm
A new study shows the potential for patients who have both addiction issues and chronic pain to get relief from an approach that combines behavioral therapy and social support to help them manage their pain without painkillers that carry an addiction risk. The low-cost approach, grounded in psychological theories of pain, could help address the nation's epidemic of addictions to opioid painkillers and illicit drugs.
