Photo captures merging shock waves made by jets Merging shock waves created by the supersonic speeds of two Air Force jets can be seen for the first time in photos taken by NASA. A plane flying over the two T-38 planes snapped the photos using air-to-air schlieren photographic technology. Live Science Optical laser probe can […]
One of the ultimate goals in surface science is to comprehend the fundamental processes that make that surface reactions need less than a picosecond (10-12 s) to occur. This means understanding what is happening at the scale of femtoseconds, that is, measuring things that take some tens or hundreds of 10-15 seconds to occur. To […]
Chemo-resistance remains a leading cause of mortality in cancer. Two recent discoveries demonstrate that some bacteria strains induce chemo-resistance, and can be targeted to increase the efficacy of therapeutic agents. The emerging relationship between the microorganisms and tumor progression has led many research groups to investigate whether the existence of a particular pattern of bacteria […]
Darwin’s great breakthrough was that of finding the only one explanation of the great variety and complexity we find in the living world, which is compatible with the fact that the matter and energy of which living beings are made of can only do what they do because of purely physical mechanisms. There is only […]
Ocean warming threatens fish populations Warming ocean temperatures due to climate change helped reduce the amount of seafood that could be sustainably caught between 1930 and 2010 by 4.1% worldwide. In some regions, such as the Sea of Japan and the northeast Atlantic, the decline is more dramatic — as much as 35%, researchers say […]
Topological materials have special universal properties, which are protected against perturbations. Such properties are theoretically described by topology, a branch of mathematics concerned with the properties of geometrical objects that are unchanged by continuous deformations. Topological materials behave like an ordinary insulator in the bulk but have conducting states on their boundaries, i.e., edges or […]

Gut microbiota has a surprising importance in processes related to the development of the nervous system, its functioning and to psychology and behavior, both in people and in animals. The microorganisms produce substances that after crossing the intestinal epithelium reach the blood and through it and after crossing the blood-brain barrier they reach the brain […]

From electric vehicles to storing wind and solar energy produced during off-peak hours, rechargeable lithium-ion (Li-ion) batteries are the best option that we currently have tu support our technological future. But if we want them to be truly environmentally-friendly and safe devices, they do need some changes. The Li-ion battery is a rechargeable cell. Typically […]
Large-scale testing of biotech mosquitoes begins Italy-based scientists have begun large-scale testing of biotech mosquitoes in a controlled laboratory that mimics their natural environment. The biotech mosquitoes have the doublesex gene mutation, resulting in malformed reproductive organs that prevent female mosquitoes from laying eggs and mouths more like those of male mosquitoes that are incapable […]
Nature is a source of inspiration for scientists. If the efficiency of natural processes efficiency has been honed by billions of years of evolution, it seems reasonable that the best way to achieve some process is to try and mimic what nature has already come up with. This is the case with photosynthesis, a process […]
