Freshly Exhumed writes "Phoronix has an article about how Dirk Hohndel of Intel's Open-Source Technology Center has stirred the hornet's nest with a talk at Australia's Linux.Conf.Au (MP4 file) about what he views as the biggest problem with the GTK: he finds dealing with upstream GTK/GNOME developers to be tough, with frequent abuse and flame-wars, with accusations from the developers that "you're doing it wrong." Conversely, he found the Qt development community to be quite the opposite: willing to engage and help, with plenty of application developer documentation and fewer communication problems than with their GTK counterparts."

If we've learned anything from post-apocalyptic movies it's that computers eventually become self-aware and try to eliminate humans. One engineer isn't interested in that development, but he has managed to eliminate the need for humans in the field of object recognition by creating an algorithm that can accurately identify objects in images or video sequences without human calibration.
Imagine seeing a dozen pictures flash by in a fraction of a second. You might think it would be impossible to identify any images you see for such a short time. However, a team of neuroscientists has found that the human brain can process entire images that the eye sees for as little as 13 milliseconds -- the first evidence of such rapid processing speed.
5,900 natural gas leaks discovered under Washington, D.C.: A dozen locations had concentrations high enough to trigger explosion
More than 5,893 leaks from aging natural gas pipelines have been found under the streets of Washington, D.C. A dozen of the leaks could have posed explosion risks, the researchers said. Some manholes had methane concentrations as high as 500,000 parts per million of natural gas -- about 10 times greater than the threshold at which explosions can occur.
Scientists have discovered the first binary system ever known to consist of a black hole and a ‘spinning’ star – or more accurately, a Be-type star. Although predicted by theory, none had previously been found.
Experts and social organizations have warned of the negative effects that the economic crisis could mean for the health of the population. But it was not easy to demonstrate with data what is happening. A new, comparative analysis of the last two National Health Surveys revealed a rise in mental health problems in men, which contrasts on the other hand with a decrease in women.
Jawbone's famous Bluetooth telephone earpiece has been redesigned. This time, it's less geeky simply because it's smaller.
The question how rapidly animals, plants or microorganisms can colonize new territories is not only of interest to ecologists – the spread of invasive species can also have economic consequences, e.g. in the agricultural sector. Scientists have now refined an existing model and, for the first time, used laboratory experiments to validate its ability to predict biological invasion dynamics.
Discovery of quantum vibrations in 'microtubules' inside brain neurons supports controversial theory of consciousness
A review and update of a controversial 20-year-old theory of consciousness claims that consciousness derives from deeper level, finer scale activities inside brain neurons. The recent discovery of quantum vibrations in "microtubules" inside brain neurons corroborates this theory, according to review authors. They suggest that EEG rhythms (brain waves) also derive from deeper level microtubule vibrations, and that from a practical standpoint, treating brain microtubule vibrations could benefit a host of mental, neurological, and cognitive conditions.
Harnessing the power of both the Hubble Space Telescope and the citizen science project Galaxy Zoo, scientists have found that bar-shaped features in spiral galaxies accelerate the galaxy aging process. The astronomers found that the fraction of spiral galaxies with bar features has doubled in the last eight billion years -- the latter half of the history of the universe.
Just a single foreign atom located in the vicinity of a molecule can change spatial arrangement of its atoms. In a spectacular experiment, an international team of researchers was able to change persistently positions of the nuclei of hydrogen atoms in a porphycene molecule by approaching a single copper atom to the molecule.
Patients with a single illness who take many drugs have an increased risk of being admitted to hospital, but for patients with multiple conditions, taking many medicines is now associated with a near-normal risk of admission. Doctors call the situation where people take many drugs ‘polypharmacy’, a state of affairs that is becoming increasingly common in part because we have more elderly people and also a rising number of people are being diagnosed with multiple health conditions.
A research team has identified a protein that increases the transfer of mitochondria from mesenchymal stem cells to lung cells. The researchers reveal that the delivery of mitochondria to human lung cells can rejuvenate damaged cells. The migration of mitochondria from stem cells to epithelial cells also helps to repair tissue damage and inflammation linked to asthma-like symptoms in mice.
Glaciers are important indicators of climate change. Global warming causes mountain glaciers to melt, which, apart from the shrinking of the Greenlandic and Antarctic ice sheets, is regarded as one of the main causes of the present global sea-level rise. Tibet’s glaciers are also losing mass clearly, as scientists reveal using satellite-based laser measurements. Over the last decade, the research team has detected a “clear loss in mass of around 16 gigatons a year in around 80 percent of the Tibetan glaciers,” says a glaciologist.
The life-threatening disease typhoid fever results from the ongoing battle between the bacterial pathogen Salmonella and the immune cells of the body. A research group has now uncovered how the typhoid pathogen repeatedly manages to evade the host’s immune system.
The brain appears to synchronize the activity of different brain regions to make it possible for a person to pay attention or concentrate on a task, scientists have learned.
Symphony of life, revealed: New imaging technique captures vibrations of proteins, tiny motions critical to human life
Like the strings on a violin or the pipes of an organ, the proteins in the human body vibrate in different patterns, scientists have long suspected. Now, a new study provides what researchers say is the first conclusive evidence that this is true.
Climate change is reportedly affecting the cultivation of tea in China, with changes in temperatures and rainfall altering not only the taste, aroma, and potential health benefits of the popular beverage but also the lives of farmers who grow tea for a living. A research team will study this development in a four-year project.
A study finds that even "minimally buzzed" drivers -- with a blood alcohol content (BAC) of 0.01 percent -- are 46 percent more likely to be officially and solely blamed by accident investigators than are the sober drivers they collide with.
Shingles, a painful blistering virus related to the chicken pox, are more common in the winter and spring than any other time of the year. While people over the age of 60 account for 50% of all shingles cases, less than 15% get a vaccine that can prevent the illness. Now, a new study is showing that simple hi- and low-tech interventions may help motivate seniors to get vaccinated. The study also suggests that the combined use of pharmacists and electronic medical records could be successfully reapplied to managing other preventable or chronic illnesses.
