Science and art bring back to life 300-million-year-old specimens of a primitive reptile-like vertebrate

Posted: 21 Jul 2014 09:37 AM PDT

Paleontologists have recreated the cranial structure of a 308-million-year-old lizard-like vertebrate that could be the earliest example of a reptile and explain the origin of all vertebrates that belong to reptiles, birds and mammals.

Mysterious dance of dwarf galaxies may force a cosmic rethink

Posted: 21 Jul 2014 07:04 AM PDT

The discovery that many small galaxies throughout the universe do not 'swarm' around larger ones like bees do but 'dance' in orderly disc-shaped orbits is a challenge to our understanding of how the universe formed and evolved. The researchers believe the answer may be hidden in some currently unknown physical process that governs how gas flows in the universe, although, as yet, there is no obvious mechanism that can guide dwarf galaxies into narrow planes.

Genetic risk for autism stems mostly from common genes

Using new statistical tools, scientists have discovered that most of the genetic risk for autism comes from versions of genes that are common in the population rather than from rare variants or spontaneous glitches.

Marmoset sequence sheds new light on primate biology and evolution

Posted: 20 Jul 2014 05:42 PM PDT

Scientists have completed the genome sequence of the common marmoset -- the first sequence of a New World Monkey -- providing new information about the marmoset's unique rapid reproductive system, physiology and growth, shedding new light on primate biology and evolution.

Eight ways zinc affects the human body

Posted: 18 Jul 2014 08:45 AM PDT

Zinc has been identified as one of the most important essential trace metals in human nutrition and lifestyle. Zinc is not only a vital element in various physiological processes; it is also a drug in the prevention of many diseases. The adult body contains about two to three grams of zinc. It is found in organs, tissues, bones, fluids, and cells.

Nature's strongest glue comes unstuck

Posted: 18 Jul 2014 06:54 AM PDT

Over a 150 years since it was first described by Darwin, scientists are finally uncovering the secrets behind the super strength of barnacle glue. Still far better than anything we have been able to develop synthetically, barnacle glue -- or cement -- sticks to any surface, under any conditions. But exactly how this superglue of superglues works has remained a mystery -- until now.

Math can make the Internet 5-10 times faster

Posted: 17 Jul 2014 06:48 AM PDT

Mathematical equations can make Internet communication via computer, mobile phone or satellite many times faster and more secure than today. A new study uses a four minute long mobile video as an example. The method used by the Danish and US researchers in the study resulted in the video being downloaded five times faster than state of the art technology. The video also streamed without interruptions. In comparison, the original video got stuck 13 times along the way.
