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

“#Conditions ripe for active Amazon fire, Atlantic hurricane seasons” The Amazon fire season forecast shows predictions for fire risk in Amazon regions with high biomass burning, namely, human-propagated fires for agriculture and land clearing. Shown are 10 Amazon regions from Brazil, Bolivia, and Peru and their fire severity risks going into the 2020 fire season….
“#Aquaculture’s role in nutrition in the COVID-19 era” Credit: CC0 Public Domain Aquaculture, the relatively young but fast-growing industry of farming of fish and other marine life, now produces around half of all seafood consumed by humans. A new paper from American University published today examines the economics of an aquaculture industry of the future…
“#Study of giant ant heads using simple models may aid bio-inspired designs” Soldier ants have giant heads with pincers that help them defend the colony. Credit: Alex Wild. Researchers use a variety of modelling approaches to study form and function. By using a basic biomechanical model for studying body form and center of mass stability…
“#Cherned up to the maximum” Crystals of PdGa can be grown with two distinctstructural chiralities (left and right column). The two enantiomers have mirrored crystalstructures (second row), as seen in electron-reflection patterns (third row). Schröter et al. nowdemonstrate that the handedness are reflected as well in the structure of the Fermi surfaces(bottom row), which determine…
“#Advanced technology sheds new light on evolution of teeth” A tropical reef in the Czech Republic, 409 million years ago: Radotina, one of the most primitive jawedvertebrates with teeth, emerges from its hiding place in the empty shell of a giant nautiloid to hunt for food. Credit: Jan Sovak The evolution of human teeth began…
“#Movement ecology bears fruits: ATLAS supports map-based navigation of wild bats” Researcher attaches ATLAS tracking collar to bat. Credit: David Shohami When wild Egyptian fruit bats set out at night to forage in Israel’s Hula Valley, they do so using advanced spatial memory and a flexible cognitive mapping of the fruit trees and other goals…
“#Socio-economic, environmental impacts of COVID-19 quantified” Global greenhouse gas emissions, incorporating data for 2020 calculated from this study. Credit: University of Sydney The first comprehensive study of the pandemic shows consumption losses amount to more than US$3.8 trillion, triggering full-time equivalent job losses of 147 million and the biggest-ever drop in greenhouse gas emissions. The…
“#Dissecting fruit flies’ varying responses to life-extension diet” A cartoon of an elderly fruit-fly enjoying his breakfast. The effects of calorie-restricted diets on fruit fly aging and lifespans is not uniform across different strains. A new study looks at small molecules involved in cell metabolism to see why this inconsistency occurs. Credit: Alice C. Gray…
“#Vulnerability for at-risk populations identified in US influenza data” This digitally-colorized transmission electron microscopic image depicts the ultrastructural details of an influenza virus particle. Credit: CDC, Frederick Murphy A next-generation system for monitoring influenza outbreaks performs well overall, but reveals a critical lack of sufficient data to accurately monitor influenza in the most at-risk communities….
