Women have many options for oral contraceptives that are safe, effective and reversible, but despite decades of research, men have none. Now, scientists report a rat study that shows they finally have a good lead for a male birth control pill. It's based on ouabain, a plant extract that African warriors and hunters traditionally used as a heart-stopping poison on their arrows.

Miles Davis is not Mozart: The brains of jazz and classical pianists work differently

#zrodlo

A musician's brain is different to that of a non-musician. Making music requires an interplay of abilities which are also reflected in more developed brain structures. Scientists have discovered that these capabilities are embedded in a much more finely tuned way than assumed: The brain activity of jazz pianists differs from those of classical pianists, even when playing the same piece of music.

A small group of fishes -- possibly the world's cleverest carnivorous grazers -- feeds on the scales of other fish in the tropics. Biologists are trying to understand these scale-feeding fish and how this odd diet influences their body evolution and behavior.

Female fiddler crabs are sensitive to changes in the speed of a male's courtship display, significantly preferring displays that accelerate to those that are performed at a constant speed or slow down.

For the first time, research has uncovered the origins of the earliest domestic turkeys in ancient Mexico. The study also suggests turkeys weren't only prized for their meat -- with demand for the birds soaring with the Mayans and Aztecs because of their cultural significance in rituals and sacrifices.

Ultra-thin optical fibers offer new way to 3-D print microstructures

Added: 17.01.2018 10:26 | 0 views | 0 comments


For the first time, researchers have shown that an optical fiber as thin as a human hair can be used to create microscopic structures with laser-based 3-D printing. The innovative approach might one day be used with an endoscope to fabricate tiny biocompatible structures directly into tissue inside the body.

Chameleons are known to communicate with conspecifics by altering their surface coloration. Munich researchers have now found that the bony tubercles on the heads of many species fluoresce under UV light and form impressive patterns.

'Rainbow' dinosaur had iridescent feathers like a hummingbird

Scientists discovered a dinosaur fossil with feathers so well-preserved that they were able to see the feathers' microscopic color-bearing structures. By comparing the shapes of those feather structures with the structures in modern bird feathers, they're able to infer that the new dino, Caihong juji ('rainbow with the big crest') had iridescent rainbow feathers like a hummingbird.

Surfers three times more likely to have antibiotic-resistant bacteria in guts

Added: 15.01.2018 16:20 | 0 views | 0 comments

#zrodlo

Scientists compared fecal samples from surfers and non-surfers to assess whether the surfers' guts contained E. coli bacteria that were able to grow in the presence of the antibiotic cefotaxime. Cefotaxime has previously been prescribed to kill off these bacteria, but some have acquired genes that enable them to survive this treatment. The study found that 13 of 143 (9 percent) of surfers were colonized by these resistant bacteria, compared to just four of 130 (3 percent) of non-surfers swabbed.

Using x-ray lasers, researchers have been able to map out how water fluctuates between two different states when it is cooled. At -44°C these fluctuations reach a maximum pointing to the fact that water can exist as two different distinct liquids.

Gyroscopes lead scientists to unusual state of matter in a disorganized structure

#zrodlo

You don't have to be perfectly organized to pull off a wave, according to scientists. Using a set of gyroscopes linked together, physicists explored the behavior of a material whose structure is arranged randomly, instead of an orderly lattice. They found they could set off one-way ripples around the edges, much like spectators in a sports arena -- a 'topological wave,' characteristic of a particularly unusual state of matter.
