Indian State Saves $45 Million As Schools Switch To Open Source Software

Slashdot - Mon, 27/02/2017 - 2:00pm
From a report: The Kerala government has made a saving of Rs 300 crore ($45 million) through introduction and adoption of Free & Open Source Software (FOSS) in the school education sector, said a state government official on Sunday. IT became a compulsory subject in Kerala schools from 2003, but it was only in 2005 that FOSS was introduced in a phased manner and started to replace proprietary software. The decision made by the curriculum committee to implement it in the higher secondary sector has also been completed now. "It's not the cost saving that matters more, but the fact that the Free Software license enables not only teachers and students but also the general public an opportunity to copy, distribute and share the contents and use it as they wish," K. Anwar Sadath, executive director IT@School said.

Involuntary urinary incontinence can discourage sufferers from exercise

Science Daily - Mon, 27/02/2017 - 1:27pm
Urinary incontinence symptoms in middle-aged woman are linked to lower levels of exercise, research shows. Involuntary urinary incontinence symptoms can discourage sufferers from partaking in exercise. However, exercise can ease symptoms by, for example, reducing obesity – as obesity increases pressure on the urethra – and strengthening pelvic floor muscles.

New evidence on the diet of the 'Homo antecessor' from Atapuerca

Science Daily - Mon, 27/02/2017 - 1:25pm
The Homo antecessor, a hominin species that inhabited the Iberian Peninsula around 800,000 years ago, would have a mechanically more demanding diet than other hominin species in Europe and the African continent. This unique pattern, which would be characterized by the consumption of hard and abrasive foods, may be explained by the differences in food processing in a very demanding environment with fluctuations in climate and food resources, according to a study.

New insights into the mechanisms into how ungulates got bigger in the Neogene

Science Daily - Mon, 27/02/2017 - 1:25pm
The observed increase of body size in ungulates during the 20 million years before the Pleistocene is driven by the process of species selection, according to researchers. Bigger ungulate species became more common because of a higher origination and lower extinction rate. The study is the first to compare the evolution of two mammalian clades during the Neogene on two continents. The researchers point out that this biogeographic perspective yields complex explanations for apparently shared patterns.

Materials that emit rainbows

Science Daily - Mon, 27/02/2017 - 1:25pm
Mechanochromic luminescent (MCL) materials change their color in response to a change in their environment, like pressure and temperature. To date, most MCL materials only change between two colors, limiting their applications. A international research team has developed tricolor-changing MLC materials. Not only that, the developed materials exhibited efficient thermally activated delayed fluorescence (TADF) and allowed high performance organic light-emitting diodes (OLEDs) devices.

New mech­an­ism un­der­ly­ing epi­lepsy found

Science Daily - Mon, 27/02/2017 - 1:25pm
Prolonged epileptic seizures may cause serious problems that will continue for the rest of a patient’s life. As a result of a seizure, neural connections of the brain may be rewired in an incorrect way. This may result in seizures that are difficult to control with medication. Mechanisms underlying this phenomenon are not entirely known, which makes current therapies ineffective in some patients.

Let it glow: Researchers design new photoluminescent compounds

Science Daily - Mon, 27/02/2017 - 1:25pm
Chemical compounds that emit light are used in a variety of different materials, from glow-in-the-dark children’s toys to LED lights to light-emitting sensors. As the demand for these compounds increases, finding new efficient methods for their production is essential. New research describes a new strategy for producing photoluminescent (PL) compounds with increased capabilities.

Changes in RNA splicing: A new mechanism for genetic risk in schizophrenia

Science Daily - Mon, 27/02/2017 - 1:22pm
New research has identified sections of DNA associated with altered regulation of gene expression underlying schizophrenia. The implicated loci contribute to schizophrenia risk by affecting alternative splicing, part of the process that translates the same DNA code into multiple different proteins.

Ketogenic diet shown safe, effective option for some with rare and severest form of epilepsy

Science Daily - Mon, 27/02/2017 - 1:21pm
In a small phase I and II clinical trial, researchers and colleagues elsewhere found that the high-fat, low-carbohydrate ketogenic diet was a safe and effective treatment option for the majority of adults experiencing a relatively rare, often fatal and always severe form of epilepsy marked by prolonged seizures that require medically induced comas to prevent them from further damaging the body and the brain.
