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

“#Desert algae shed light on desiccation tolerance in green plants” Desert derived green algae (Acutodesmus deserticola) in culture at the Marine Biological Laboratory. Credit: Elena Lopez Peredo Deserts of the U.S. Southwest are extreme habitats for most plants, but, remarkably, microscopic green algae live there that are extraordinarily tolerant of dehydration. These tiny green algae…
“#A tiny ancient relative of dinosaurs and pterosaurs discovered” Illustration of Kongonaphon kely, a newly described reptile near the ancestry of dinosaurs and pterosaurs, in what would have been its natural environment in the Triassic (~237 million years ago). Credit: Alex Boersma Dinosaurs and flying pterosaurs may be known for their remarkable size, but a…
“#First direct evidence of ocean mixing across the Gulf Stream” The “Triaxus” towing platform breaks through the choppy surface of the ocean during a storm. By towing such a platform with monitoring instruments through the water, changing its depth in a ‘yo-yo’ pattern as it traveled, scientists created high-resolution snapshots of how a dye released…
“#Behind the dead-water phenomenon” What makes ships mysteriously slow down or even stop as they travel, even though their engines are working properly? This was first observed in 1893 and was described experimentally in 1904 without all the secrets of this “dead water” being understood. A French team has explained this phenomenon for the first…
“#Herpesvirsuses hedge their bets to optimize survival” Credit: CC0 Public Domain When investors hedge a bet, they divvy their money between risky investments, which might make a large profit, and safe investments, which help ensure that not everything is lost in a market crash. The herpesvirus cytomegalovirus, Gladstone researchers have discovered, takes a similar approach…
“#Team obtained high-level control of spin qubit lifetime based on silicon quantum dots” Credit: CC0 Public Domain By tuning the direction of the external magnetic field with respect to the crystallographic axis of the silicon wafer, an improvement of spin lifetime (relaxation time) by over two orders of magnitude was reported in silicon quantum dots….
“#Owner behavior affects effort and accuracy in dogs’ communications” Owners influence how well dogs show where a toy is hidden. Credit: Theresa Epperlein Human communication has evolved mechanisms that can be observed across all cultures and languages, including the use of communication history and the principle of least effort. These two factors enable us to…
“#Researchers realize an anomalous Floquet topological system” Credit: CC0 Public Domain An international team led by physicists from the Ludwig-Maximilians Universitaet (LMU) in Munich realized a novel genuine time-dependent topological system with ultracold atoms in periodically-driven optical honeycomb lattices. Topological phases of matter have attracted a lot of interest due to their unique electronic properties…
“#Norman Conquest of 1066 did little to change people’s eating habits” Credit: Unsplash/CC0 Public Domain Archaeologists from Cardiff University and the University of Sheffield have combined the latest scientific methods to offer new insights into life during the Norman Conquest of England. Until now, the story of the Conquest has primarily been told from evidence…
“#Researchers design artificial genes to sense cellular responses to drugs” Credit: CC0 Public Domain Researchers from Boston University School of Medicine (BUSM) have developed and implemented a new way to better understand how human cells communicate with each other, how this communication is disrupted in human diseases and how this can be corrected pharmacologically. Their…
