I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.

“#Levitating droplets allow scientists to perform ‘touchless’ chemical reactions” Levitating droplets of acidic and basic solutions (left) merge into a larger droplet (right), in which carbon dioxide bubbles form as a product of the reaction. Credit: Analytical Chemistry 2020, DOI: 10.1021/acs.analchem.0c00929 Levitation has long been a staple of magic tricks and movies. But in the…
“#How to prolong shelf life and avoid food waste” Credit: MIA Studio, Shutterstock About a third of all food produced for human consumption is lost or wasted globally each year, according to a report by the Food and Agricultural Organization of the United Nations. In the EU, this amount is about 20% of the total…
“#Economic alien plants more likely to go wild” Oxalis pes-caprae or Bermuda buttercup is native to South Africa, and has been introduced elsewhere as bee plant (for honey production) and for ornamental purposes. It is now widely naturalized elsewhere, like here on Crete (Greece). Credit: Mark van Kleunen An international team of researchers led by…
“#Molecular simulations show how drugs block key receptors” Credit: CC0 Public Domain Many pharmaceuticals work by targeting what are known as ‘G-protein-coupled receptors.’ In a new study, scientists from Uppsala University describe how they have been able to predict how special molecules that can be used in new immunotherapy against cancer bind to these receptors….
“#Every moment of ultrafast chemical bonding captured on film” The bond formation reaction in a gold trimer complex is initiated by a laser pulse, and a three-dimensional structure after a certain time delay is detected by an x-ray scattering image. Credit: IBS Targeted cancer drugs work by striking a tight bond between cancer cells and…
“#Much improved climate predictions from statistical mechanics” Credit: CC0 Public Domain A study from the European Horizon 2020 TiPES project confirms that the large uncertainties of climate models used in the IPCC reports might be reduced considerably by the use of statistical mechanics. The technique, which has been regarded with skepticism by some experts, leads…
“#Imaging magnetic instabilities using laser accelerated protons” Protons accelerated by laser-plasma interaction in a first target (left) pass through a second target, itself irradiated by another laser beam (middle and framed). The Weibel instability induced there by energetic electrons (blue trajectories) generates magnetic fluctuations that deflect the protons onto a series of sensitive films (right),…
“#Removing toxic chemicals from water: New environmentally-friendly method” Credit: CC0 Public Domain Researchers from Swansea University have developed a new environmentally friendly method for removing toxic chemicals from water. A newly invented machine, called the Matrix Assembly Cluster Source (MACS), has been used to design a breakthrough water treatment method using a solvent-free approach. The…
“#Order out of disorder in ice” An illustration shows structural evolution of ice VII as a function of time at constant P-T conditions. Credit: Center for High Pressure Science & Technology Advanced Research The glass structure of a material is often believed to mimic its corresponding liquid. Polyamorphism between ices has been used as a…
