| Mind-controlled prosthetic arm moves individual ‘fingers’ Posted: 15 Feb 2016 12:46 PM PST Physicians and biomedical engineers from Johns Hopkins report what they believe is the first successful effort to wiggle fingers individually and independently of each other using a mind-controlled artificial "arm" to control the movement. |
| Using light to control protein transport from cell nucleus Posted: 15 Feb 2016 09:37 AM PST Light can be used to control the transport of proteins from the cell nucleus with the aid of a light-sensitive, genetically modified plant protein. Biologists working in the field of optogenetics have now developed such a tool. The researchers employed methods from synthetic biology and combined a light sensor from the oat plant with a transport signal. This makes it possible to use external light to precisely control the location and hence the activity of proteins in mammalian cells. |
| Jawless fish brains more similar to ours than previously thought Posted: 15 Feb 2016 08:40 AM PST Researchers have shown that complex divisions in the vertebrate brain first appeared before the evolution of jaws, more than 500 million years ago. The study shows that two elements of brain genoarchitecture thought to be unique to jawed vertebrates are actually present in two jawless fish -- the hagfish and lamprey. |
| Scientists discover new microbes that thrive deep in the earth Posted: 15 Feb 2016 08:40 AM PST They live several kilometers under the surface of the earth, need no light or oxygen and can only be seen in a microscope. By sequencing genomes of a newly discovered group of microbes, the Hadesarchaea, an international team of researchers have found out how these microorganisms make a living in the deep subsurface biosphere of our planet. |
| The mystery about the Chelyabinsk superbolide continues three years later Posted: 15 Feb 2016 06:06 AM PST Hundreds of webcams recorded the historic event: In 2013 February 15, the approach of asteroid (367943) Duende to our planet was being closely monitored by both the public and the scientific community worldwide when suddenly a superbolide entered the atmosphere above the region of Chelyabinsk in Russia. Three years and hundreds of published scientific studies later, we are still looking for the origin of such unexpected visitor, that caused damage to hundreds of buildings and injuries to nearly 1,500 people. |
| Sex with the other species: Tree frogs with foreign sex chromosomes are less fit Posted: 15 Feb 2016 06:05 AM PST During the last glaciation, a huge ice shield reached up to the region of today's Berlin. By the time it started to melt about 20,000 years ago, it enabled a gradual re-colonization of the northern latitudes by many plant and animal species. Often, they took different colonization routes around the mountain ranges, for example the Carpathians - with astonishing outcomes for a special kind of re-unification that, for instance, happens in Poland: In the region of the Vistula River, two evolutionarily young species of tree frogs meet each other. |
