A new imaging system is capable of obtaining up to twelve times more color information than the human eye and conventional cameras, which implies a total of 36 color channels.
The system involves a new generation of sensors in combination with a matrix of multispectral filters to improve their performance.
Social network analysis could improve knowledge sharing in the healthcare sector, according to a paper which shows how knowledge management systems (KMS) can be critical in capturing, retaining and communicating project results and staff knowledge. They can prevent knowledge drain and provide training as "lessons learned" following specific occurrences and the resolution of particular problems the staff face.
When you take a shower and use soap and then lather, rinse and repeat twice with that shampoo, it gets washed off your body and goes down the drain.
Environmentalists have claimed these soaps and shampoos and washing machine detergents - surfactants - seep into groundwater, lakes and streams, where they could pose a risk to fish and frogs.
But do they? Not likely, finds a new report of the potential impact on the environment of the enormous amounts of common surfactants used day in and day out by consumers all over the world.

Hippocrates is considered the father of medicine, enemy of superstition, pioneer of rationality and fount of eternal wisdom.
Statues and drawings show him with a furrowed brow, thinking hard about how to heal his patients.

From the “best beaches” to the “best slice of pizza” to the best hospital to have cardiac surgery in, we are inundated with a seemingly never-ending series of reports ranking everything that can be ranked and even things that probably shouldn’t be.-->
Look at a fan rotating its blades. Now look somewhat to the side of it. It seems to rotate slower now. Now shift your gaze slowly back toward the center of the fan. The fan seems to pick up speed. There are not just two appearances of its speed, one fast if I stare at it, and one slow if it is in the periphery of my visual field, but instead the fan seems to pick up speed gradually!-->
Call it cathartic but one modern way people in a bad mood feel better is to go on social media like Facebook and find friends doing even worse.
A new paper says that generally people use social media to connect with people who are posting positive and success-oriented updates. No one wants to hang out with downers - unless they are in a bad mood. Then people want to read about less attractive, less successful and more miserable people. The authors believe the
findings give more context to recent papers stating that found people who spend a lot of time on Facebook tend to be more frustrated, angry and lonely – presumably because of all the happy updates from friends that make them feel inadequate.
A new study has found that lungs become more inflammatory with age and that ibuprofen can lower that inflammation - and the difference can be dramatic.
Immune cells from old mouse lungs, after lung inflammation was reduced by ibuprofen, fought tuberculosis bacteria as effectively as cells from young mice. The ibuprofen had no effect on the immune response to TB in young mice. The researchers already knew that old mice had a harder time clearing TB from the lungs than young mice, but had not investigated the role of lung inflammation in that response.
The idea of evolutionary imbalance when it comes to invasive species is not new, Charles Darwin articulated it.
The concept is that species from regions with deep and diverse evolutionary histories are more likely to become successful invaders in regions with less deep, less diverse evolutionary histories. Darwin's original insight was that the more challenges a region's species have faced in their evolution, the more robust they'll be in new environments.
To predict the probability of invasiveness, ecologists

Researchers recently used audio and video recording tools to record larval orientation behavior in the pelagic environment.
In their field experiment, the scientists put the recording devices i a drifting in situ chamber called DISC near Fowey Rocks lighthouse in the northern Florida Keys. In total 58 deployments were conducted, 27 during the day and 31 at night. The team also recorded sounds in a laboratory setting to confirm that the sounds observed in the field were from gray snapper larvae. The researchers also referred to the public sound archive at the Macaulay Library to compare the larval sounds to those produced by adult L. griseus.

Some sharks are more 'gregarious' than others and have strong social connections while others are solitary and prefer to remain inconspicuous. That's not an exception, according to a new study, these notorious predators have personality traits.
Personalities obviously exist in many animals but they are usually defined by individual characteristics such as how exploratory, bold or aggressive an individual animal is. The paper in
the journal Behavioral Ecology and Sociobiology involved testing for social personality by recording the social interactions of groups of juvenile small spotted catsharks in captivity under three different habitat types.
Abortion and teen pregnancy dropped among teens who received free contraception and were educated about the pros and cons of various birth control methods, according to a new study in the New England Journal of Medicine.
