DNA testing challenges traditional species classification

Science Daily - Fri, 24/06/2016 - 3:03pm
Experts have made a surprising discovery that could subvert the significance of traditional criteria used for species classification. Employing novel techniques to retrieve DNA sequences from thousands of genomic locations, the researchers were able to uncover an unusual case of cryptic speciation in the Streak-eared Bulbul [Pycnonotus blanfordi], a bird widespread throughout South-east Asian countries.

Researchers offer new theory on how climate affects violence

Science Daily - Fri, 24/06/2016 - 3:00pm
Researchers have long struggled to explain why some violent crime rates are higher near the equator than other parts of the world. Now, a team of researchers has developed a model that could help explain why.

Eyewitnesses who collaborate make fewer mistakes in police interview

Science Daily - Fri, 24/06/2016 - 3:00pm
Witnesses correct each other's errors. Two recently published research studies show that witnesses make fewer errors when they are interviewed together than when they are interviewed separately. This stands in sharp contrast with current police guidelines to always interview witnesses separately.

'Flower Power': Photovoltaic cells replicate rose petals

Science Daily - Fri, 24/06/2016 - 3:00pm
With a surface resembling that of plants, solar cells improve light-harvesting and thus generate more power. Scientists reproduced the epidermal cells of rose petals that have particularly good antireflection properties and integrated the transparent replicas into an organic solar cell. This resulted in a relative efficiency gain of twelve percent.

New tool to measure polarization of light

Science Daily - Fri, 24/06/2016 - 2:59pm
Researchers have developed a new tool for detecting and measuring the polarization of light based on a single spatial sampling of the light, rather than the multiple samples required by previous technologies. The new device makes use of the unique properties of organic polymers, rather than traditional silicon, for polarization detection and measurement.

Should first-year college students assessed as needing remedial math take college-level quantitative courses instead?

Science Daily - Fri, 24/06/2016 - 2:52pm
Policies placing first-year college students assessed as needing remedial math directly into college-level quantitative courses, with additional support, can increase student success, according to a first-of-its-kind study.

Aggressiveness of acute myeloid leukemia elucidated

Science Daily - Fri, 24/06/2016 - 2:47pm
Scientists have discovered why acute leukemias with the same genetic abnormality vary in their aggressiveness based on their cellular origin. They found that the cancer inducing alteration is particularly devastating if it occurs in early hematopoietic stem cells expressing certain genes involved in cell migration and tissue invasion. These findings should now make it possible to classify patients into more clearly defined groups, to adapt treatment, and hopefully also to develop personalized therapeutic strategies for the future.

New treatment approaches to improve peritoneal dialysis

Science Daily - Fri, 24/06/2016 - 2:47pm
One of the main functions of the kidneys is to filter metabolic products out of the blood. If the kidneys are no longer able to do this, the blood has to be artificially purified and drained of excess fluid. This is the purpose of dialysis. Now researchers are seeking new, better therapeutic approaches for those patients on dialysis.

'Godless' Apps, Some Found In Google Play, Root 90% Of Android Phones

Slashdot - Fri, 24/06/2016 - 2:40pm
Dan Goodin, reporting for ArsTechnica:Researchers have detected a family of malicious apps, some that were available in Google Play, that contain malicious code capable of secretly rooting an estimated 90 percent of all Android phones. In a recently published blog post, antivirus provider Trend Micro said that Godless, as the malware family has been dubbed, contains a collection of rooting exploits that works against virtually any device running Android 5.1 or earlier. That accounts for an estimated 90 percent of all Android devices. Members of the family have been found in a variety of app stores, including Google Play, and have been installed on more than 850,000 devices worldwide. Godless has struck hardest at users in India, Indonesia, and Thailand, but so far less than 2 percent of those infected are in the US. Once an app with the malicious code is installed, it has the ability to pull from a vast repository of exploits to root the particular device it's running on. In that respect, the app functions something like the many available exploit kits that cause hacked websites to identify specific vulnerabilities in individual visitors' browsers and serve drive-by exploits.Affected apps that have been spotted in Google Play, Android's marquee app store, are largely flashlight, Wi-Fi apps, as well as copies of popular games.

Analysis of media reporting reveals new information about snakebites and how and when they occur

Science Daily - Fri, 24/06/2016 - 2:11pm
A new study analyzed media reports of snakebites in the United States. Investigators found that media coverage detailed victim circumstances better than current quantitative data, and that the majority of snakebites may actually be 'legitimate,' meaning they occur by surprise, without intentional contact, in a natural setting.

Analysis of genetic repeats suggests role for DNA instability in schizophrenia

Science Daily - Fri, 24/06/2016 - 2:11pm
An international research team has revealed extensive genetic variation in patients with schizophrenia. Significantly more copy number variations (CNVs) of genomic DNA were detected in patients than in controls. Patients also showed different disease severity, which appears associated with the CNVs' number and variable expressivity. These findings enabled the researchers to propose a genetic model of schizophrenia in which genomic instability underlies disease development.

People with low birthweight due to genetic factors are more likely to develop type 2 diabetes

Science Daily - Fri, 24/06/2016 - 2:08pm
A genetically lowered birthweight increases the risk of developing type 2 diabetes, new research shows. Since low birthweight represents restricted intrauterine growth (fetal growth), it cannot be ruled out that it is in fact the risk factors for this restricted growth that are causing the low birthweight and in turn causing the type 2 diabetes to develop. Risk factors for restricted intrauterine growth include malnutrition, anemia, infections and placental insufficiency.
