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

“#Researchers control elusive spin fluctuations in 2-D magnets” Credit: CC0 Public Domain Like Bigfoot and the Loch Ness monster, critical spin fluctuations in a magnetic system haven’t been captured on film. Unlike the fabled creatures, these fluctuations—which are highly correlated electron spin patterns—do actually exist, but they are too random and turbulent to be seen…
“#Anammox bacteria generate energy from wastewater while taking a breath” Anammox bacteria grew on the surface of an electrode and converted ammonium to nitrogen gas. The electrons released from this process flow through the electrode in the form of an electric current that can be used to generate energy-rich hydrogen gas. This is a step…
“#A new theory about political polarization” Credit: CC0 Public Domain The ever-deepening rift between the political left- and right-wing has long been puzzling theorists in political science and opinion dynamics. An international team led by researchers of the Complexity Science Hub Vienna (CSH) now offers an explanation: Their newly developed ‘Weighted Balance Theory’ (WBT) model…
“#Casting a wider net: New system measures brain activity of several zebrafish concurrently” Example of EEG signals detected during baseline recording and during the application of convulsant. (a) shows the EEG signal from a fish that hadn’t been treated by anti-epileptic drug (AED) while (b) shows the signal from a fish that had been treated…
“#Bleaching affects aquarium corals, too” The Australian saucer coral (Homophyllia australis), lives just off the coast of Mackay. With the worldwide demand for Australian aquarium corals increasing, a single aquarium specimen of Homophyllia australis fetched more than $8,000 AUD in Japan in 2017. However, bleaching events kill this particular species. Credit: Ciemon Caballes. A new…
“#Development of a small sensor capable of continuously monitoring the phytohormone ethylene” A small, highly sensitive sensor capable of detecting ethylene with great selectivity. Credit: NIMS NIMS and AIST have developed a small sensor capable of continuously monitoring the plant hormone ethylene. Ethylene gas promotes ripening in fruits and vegetables, but excessive exposure promotes them…
“#Team shows how to store data using 2-D materials instead of silicon chips” This illustrates how an experimental memory technology stores data by shifting the relative position of three atomically thin layers of metal, depicted as gold balls. The swirling colors reveal how a shift in the middle layer affects the motion of electrons in…
“#Global warming will cause ecosystems to produce more methane than first predicted” Credit: CC0 Public Domain New research suggests that as the Earth warms natural ecosystems such as freshwaters will release more methane than expected from predictions based on temperature increases alone. The study, published today in Nature Climate Change, attributes this difference to changes…
“#New 3-D model shows how the paradise tree snake uses aerial undulation to fly” The paradise tree snake mid-glide during the team’s motion experiments. Credit: Jake Socha When the paradise tree snake flies from one tall branch to another, its body ripples with waves like green cursive on a blank pad of blue sky. That…
“#A new antibiotic binding site found in the ribosome” Credit: CC0 Public Domain A group of scientists from Russia, Germany and the United States, led by Skoltech scientists Ilya Osterman, Petr Sergiev, Olga Dontsova and Daniel Wilson from Hamburg University, has studied the mechanism by which tetracenomycin X works, blocking the process of protein synthesis…
