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

“#A continental-scale prediction on the functional diversity of stream microbes” Credit: CC0 Public Domain A recent research find indicates that climate change increases the functional diversity of microbes living in streams. Consequently, climate change may, in certain cases, be beneficial to ecosystems. The functional genes of microbes and their sufficient diversity are important indicators of…
“#Modeling neuronal cultures on ‘brain-on-a-chip’ devices” This figure depicts Lawrence Livermore National Laboratory’s “brain-on-a-chip” device (top). Electrical recordings from the chip (lower left), taken from seeded neurons, are used to model correlations between electrodes (center), and these correlations are used to create a model of the network structure in the chip (lower right).

“#Scientists find key factors impacting sideswiping tropical cyclone precipitation” Extreme STP events may cause flooding, landslides and debris flow. Credit: screenshot from a surveillance video in Haikou, Hainan, with permission from the local meteorological administration. Sideswiping tropical cyclones (STCs) are tropical cyclones (TCs) that cause precipitation over land without making landfall. STC precipitation (STP) can…
“#What has caused more extreme summer heat events over northeast Asia?” More frequent heatwaves over Northeast Asia since 1990s. Credit: Ren Liwen Widespread hot extremes have been seen throughout the world in recent years, causing heat-related mortality and harming crops and livestock. In summer 2018, a record-breaking heat wave swept across large areas of Northeast…
“#New 3-D X-ray technique reveals secrets from inside bones” Credit: Tilman Grünewald An international research team has used new X-ray techniques to describe how the architecture of healthy human bones is built up. The team has uncovered a hitherto unknown structure in healthy bones. The human bone is a wonderful and fantastic biological material. Bone…
“#Researchers discover what’s behind nature’s perhaps largest erection, which is not that big” Microscopic photo of a normal pollentube and a pollentube with essential growth-genes turned off.

“#Unpacking the two layers of bacterial gene regulation during plant infection” A colony of the bacterial pathogen Pseudomonas syringae (green) in an Arabidopsis thaliana leaf (magenta: plant structures called chloroplasts). Credit: Tatsuya Nobori A study in Nature Plants has revealed new insights into how pathogenic bacteria regulate gene expression during plant infection, as well as…
“#Salt solution produces better organic electrochemical transistors” A KAUST team has chosen a simple technique using the ammonium salt tetra-n-butylammonium fluoride as an n-dopant and the conjugated polymer P-90 as a mixed conductor. Credit: KAUST; Heno Hwang Doping is commonly used to improve performance in semiconducting devices but has not previously been successful for electron…
“#A quantum memory that operates at telecom wavelengths” Scanning electron micrograph of the opto-mechanical device used as a quantum memory. Credit: Gröblacher Lab, TU Delft. To create large quantum networks, researchers will first need to develop efficient quantum repeaters. A key component of these repeaters are quantum memories, which are the quantum-mechanical equivalents of more…
“#Key workers are lowest paid with poorer job qualities, study finds” Key worker at Waitrose during the lockdown. Credit: Guy Bell/Rex/Shutterstock A study led by Dr. Matt Barnes, Senior Lecturer from the Department of Sociology, suggests that key worker jobs including check-out operators, care workers, food operatives and security guards receive lower pay and experience…
