Open Source Pioneer Michael Tiemann On the Myth of the Average

Slashdot - Wed, 03/02/2016 - 5:13pm
StewBeans writes: In a recent article, Michael Tiemann, one of the world's first open source entrepreneurs and VP of Open Source Affairs at Red Hat, highlights an example from the 1950s US Air Force where the "myth of the average resulted in a generation of planes that almost no pilots could reliably fly, and which killed as many as 17 pilots in a single day." He uses this example to argue that IT leaders who think that playing it safe means being as average as possible in order to avoid risks (i.e. "Buy what others are buying. Deploy what others are deploying. Manage what others are managing.") may be making IT procurement and strategy decisions based on flawed data. Instead, Tiemann says that IT leaders should understand elements of differentiation that are most valuable, and then adopt the standards that exploit them. "Don't aim for average: it may not exist. Aim for optimal, and use the power of open source to achieve what uniquely benefits your organization."

Location may be key to effectively controlling pain

Science Daily - Wed, 03/02/2016 - 4:10pm
In real estate, location is key. It now seems the same concept holds true when it comes to stopping pain. New research indicates that the location of receptors that transmit pain signals is important in how big or small a pain signal will be -- and therefore how effectively drugs can block those signals.

Researchers urge caution on wearable health devices

Science Daily - Wed, 03/02/2016 - 4:10pm
Wearable devices to monitor health are not always reliable or secure according to research. The market for digital devices like smartwatches and fitness bands is growing, with 19 million likely to be sold worldwide this year. They can measure everything from heart rate to physical activity, temperature and even mental wellbeing.

Researchers discover new phase of boron nitride and a new way to create pure c-BN

Science Daily - Wed, 03/02/2016 - 4:09pm
Researchers have discovered a new phase of the material boron nitride, which has potential applications for both manufacturing tools and electronic displays. The researchers have also developed a new technique for creating cubic boron nitride (c-BN) at ambient temperatures and air pressure, which has a suite of applications, including the development of advanced power grid technologies.

New study challenges Jupiter's role as planetary shield, protecting Earth from comet impacts

Science Daily - Wed, 03/02/2016 - 4:09pm
Not only is the 'Jupiter as shield' concept, implying that the planet shields Earth from comet impacts, not true, but perhaps Jupiter's most important role in fostering the development of life on Earth was just the opposite -- delivering the volatile materials from the outer Solar System needed for life to form. This new simulation study, and the previously underestimated role that Saturn may have also played in the evolution of life on Earth.

Enzyme key to link between age-related inflammation and cancer

Science Daily - Wed, 03/02/2016 - 4:09pm
For the first time, researchers have shown that an enzyme key to regulating gene expression -- and also an oncogene when mutated -- is critical for the expression of numerous inflammatory compounds that have been implicated in age-related increases in cancer and tissue degeneration. Inhibitors of the enzyme are being developed as a new anti-cancer target.

Galactic center's gamma rays unlikely to originate from dark matter, evidence shows

Science Daily - Wed, 03/02/2016 - 4:09pm
Studies by two independent groups from the US and the Netherlands have found that gamma ray signals from the inner galaxy come from a new source rather than from the collision of dark matter particles. The new source is likely to be rapidly rotating pulsars, rather than the as-yet undetected invisible dark matter particles thought to make up 85 percent of the mass in the Universe.

Orangutans: Lethal aggression between females

Science Daily - Wed, 03/02/2016 - 4:09pm
Researchers have for the first time witnessed the death of a female orangutan at the hands of another female. Even more extraordinary is that the perpetrator recruited a male orangutan as a hired gun to help her corner and attack the victim. Before this observation, lethal fights between females had never been observed in orangutans.

Examining how terrestrial life's building blocks may have first formed

Science Daily - Wed, 03/02/2016 - 4:08pm
How did life begin? This is one of the most fundamental questions scientists puzzle over. To address it, they have to look not just back to the primordial Earth, but out into space. Now, scientists propose a new set of cosmic chemical reactions that could have contributed to the formation of life on our planet.

It's well known that peanuts can cause severe reactions in people who are allergic, but research suggests that the risk of developing a life-threatening reaction could be higher for those allergic to cashews. Now scientists have come up with a fast and simple method to purify the three main cashew allergens to help better grasp how they work and their effects on people.
