Breakthrough in stem cell culturing
(PhysOrg.com) -- For the first time, human embryonic stem cells have been cultured under chemically controlled conditions without the use of animal substances, which is essential for future clinical uses. The method has been developed by researchers at Karolinska Institutet and is presented in the journal Nature Biotechnology.
Classic grammar model can be used for computerised parsing
A classic Nordic grammar model can be used for computerised grammatical analyses and technical applications of modern Swedish text, shows a new thesis in the field of language technology from the University of Gothenburg, Sweden. One such application enables queries answered by a digital text to be generated when it is opened, and then used to search for specific information in the text.
Education helps against dementia
Researchers have discovered that education not only delays the early symptoms of dementia, but can also slow down the development of the disease - a finding that could result in faster diagnosis and treatment of dementia, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden.
New space station crew will bid farewell to shuttle
One Russian and two Americans set to fly to the International Space Station voiced nostalgia Monday for the retiring US space shuttle, which will make its final visit to the ISS this year.
Scientists warn of unseen deepwater oil disaster

Study: 10 minutes of exercise, hour-long effects
(AP) -- Ten minutes of brisk exercise triggers metabolic changes that last at least an hour. The unfair news for panting newbies: The more fit you are, the more benefits you just might be getting.
Tecnalia presents electric vehicle that reaches 140 km/h in 10 seconds
The Tecnalia Technological Corporation (Spain) has presented its experimental vehicle -- 'Dynacar' -- , an electric car that can reach a speed of 140 kilometres per hour in 10 seconds.
What happens when we get angry?
When we get angry, the heart rate, arterial tension and testosterone production increases, cortisol (the stress hormone) decreases, and the left hemisphere of the brain becomes more stimulated. This is indicated by a new investigation lead by scientists from the University of Valencia (UV) that analyses the changes in the brain's cardiovascular, hormonal and asymmetric activation response when we...
Apple sells two million iPads
Apple, now the largest US technology company by value, said Monday it had sold two million of its iPad tablet computers, outdoing even the iconic iPhone on its launch.
Crystallisation drives controlled assembly of nanoparticles
(PhysOrg.com) -- A collaboration between researchers at the University of Bristol, England, and the University of Toronto, Canada, has led to the discovery of a new self-assembly method for controlling the dimensions of nano-cylinders.

New mechanism of pancreatic cancer discovered
(PhysOrg.com) -- A new study from Karolinska Institutet, Sweden, shows how two types of cell change interact in the development of cancer. The results can improve the chances of early discovery of cancer - including pancreatic cancer, one of the deadliest forms of the disease.
New OLETs emit light more efficiently than equivalent OLEDs
(PhysOrg.com) -- Already, organic light-emitting diodes (OLEDs) are becoming commercialized for light display applications due to their advantages such as low fabrication costs and large-area emission. But OLEDs also have intrinsic efficiency limitations due to their structure, which might limit their future development in terms of brightness. Now, a team of researchers has found that another...
A new theory to explain superrotation on Venus
(PhysOrg.com) -- One of the mysteries in our Solar System is superrotation, a phenomenon known since the late 1960s, in which the winds on Venus blow faster than the planet rotates. Scientists have proposed a number of theories, but none have been completely satisfactory. Now scientists in Mexico have for the first time suggested a viable mechanism by which a faster wind higher above the planet is...

Comparision of overall survival for non-small cell lung cancer patients
There's debate about the best treatment approach for patients with certain stages of non-small cell lung cancer (NSCLC), which accounts for about 80 percent of all lung cancers. Patients with early stages of NSCLC are typically treated with surgery, but those with stage IIIA present more of a challenge because they are such a diverse group. However, research from Fox Chase Cancer Center shows...
