China Gives Microsoft 20 Days To Respond To Competition Probe

Slashdot - Mon, 01/09/2014 - 2:12pm
An anonymous reader writes "China has given Microsoft three weeks to explain "compatibility issues" in Windows and Office that could violate Chinese competition laws. The State Administration for Industry and Commerce (SAIC) questioned Microsoft Vice President David Chen and gave the company a deadline to make an explanation, the agency said in a short statement on its website. Microsoft's use of verification codes also spurred complaints from Chinese companies. Their use "may have violated China's anti-monopoly law", the official Xinhua news agency said on Monday."

Two Common Misconceptions About Learning

Wired News - Mon, 01/09/2014 - 1:29pm
It’s another semester with a new group of students. This semester, I have a class of elementary education majors (using Physics and Everyday Thinking). In the course, students build basic physics ideas after collecting data from particular experiments. Overall, this is an awesome course. It seems that most of the students gain a greater understanding […]

Saturn's F Ring Is Now Three Times As Wide As During the Voyager Flybys

Slashdot - Mon, 01/09/2014 - 1:13pm
KentuckyFC writes In 1980 and 1981, Voyager 1 and 2 flew past Saturn providing unprecedented images of its magnificent ring system. At that time, its most distant discrete ring, the F ring, was about 200 kilometres wide. But puzzlingly, images sent back by Cassini show that the ring is now 580 kilometres wide and twice as bright as it was thirty years ago. Now astronomers think they have finally solved the mystery of the expanding F ring. The ring is shepherded by a number of small moons, the most famous of which is Prometheus. These moons interact gravitationally with the ring creating structures such as braids and spokes. The new thinking is that the moons' orbits resonate with the F ring, pushing clouds of dust and ice further away from Saturn. This makes the ring wider. But beyond a certain radius the orbit of the dust becomes unstable and it begins to spiral back towards Saturn and collides with the rest of the ring. This causes a chain reaction of collisions that dramatically increases the number of particles in the ring and hence its brightness. This theory also leads to a prediction--the resonant process is currently at a maximum but should reduce sharply in the coming years, if the theory is correct. So by 2018, the F ring should be back to the same configuration the Voyagers saw in 80/81.

Why plants in the office make us more productive

Science Daily - Mon, 01/09/2014 - 1:07pm
'Green' offices with plants make staff happier and more productive than 'lean' designs stripped of greenery, new research shows. The team examined the impact of 'lean' and 'green' offices on staff's perceptions of air quality, concentration, and workplace satisfaction, and monitored productivity levels over subsequent months in two large commercial offices in the UK and The Netherlands.

New tuberculosis blood test in children: reliable, highly specific

Science Daily - Mon, 01/09/2014 - 1:07pm
A new blood test provides a fast and accurate tool to diagnose tuberculosis in children, a new proof-of-concept study shows. The newly developed test is the first reliable immunodiagnostic assay to detect active tuberculosis in children. The test features excellent specificity, a similar sensitivity as culture tests in combination with speed of a blood test. The promising findings are a major advance for the diagnosis of tuberculosis in children, particularly in tuberculosis-endemic regions.

Invisible blood in urine may indicate bladder cancer

Science Daily - Mon, 01/09/2014 - 1:07pm
One in 60 people over the age of 60 who had invisible blood in their urine -- identified by their GP testing their urine -- transpired to have bladder cancer, researchers report. The figure was around half of those who had visible blood in their urine -- the best known indicator of bladder cancer. However, it was still higher than figures for other potential symptoms of bladder cancer that warrant further investigation.

Carcinogenic role of protein in liver decoded

Science Daily - Mon, 01/09/2014 - 1:03pm
The human protein EGFR controls cell growth. It has mutated in case of many cancer cells or exists in excessive numbers. For this reason it serves as a point of attack for target-oriented therapies. A study group has now discovered that the risk of this protein does not -- as previously assumed -- depend on its presence within the tumor cell, but rather from its activity in the cells adjacent to the tumor.

Neurons in human skin perform advanced calculations

Science Daily - Mon, 01/09/2014 - 1:03pm
Neurons in human skin perform advanced calculations, previously believed that only the brain could perform. A characteristic of neurons that extend into the skin and record touch, is that they branch in the skin so that each neuron reports touch from many highly-sensitive zones on the skin. According to researchers, this branching allows first-order tactile neurons not only to send signals to the brain that something has touched the skin, but also process geometric data about the object touching the skin.

Plant life forms in the fossil record: When did the first canopy flowers appear?

Science Daily - Mon, 01/09/2014 - 1:01pm
Most plant fossils are isolated organs, making it difficult to reconstruct the type of plant life or its ecosystem structure. Botanists have now used leaf vein density, a trait visible on leaf compression fossils, to document the occurrence of stratified forests with a canopy dominated by flowering plants.
