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

“#Not so robust: Robusta coffee more sensitive to warming than previously thought” Robusta coffee production in the Central Highlands of Vietnam. Credit: Laurent Bossolasco Even the toughest coffee trees may be no match for climate change. A new study of the plant that produces robusta coffee suggests its heat tolerance has been consistently overestimated. Worse…
“#Artificial night sky poses serious threat to coastal species” The sand hopper (Talitrus saltator) is a common feature of Europe’s coasts. Credit: John Spicer, University of Plymouth The artificial lighting which lines the world’s coastlines could be having a significant impact on species that rely on the moon and stars to find food, new research…
“#Changing environment at home genetically primes invasive species to take over abroad” The copepod Eurytemora affinisis a small, ubiquitous crustacean found throughout the world’s oceans. It has also managed to invade freshwater lakes. Credit: Carol Eunmi Lee University of Wisconsin-Madison scientists have found that a constantly fluctuating environment can enable some species to invade new…
“#Evidence supports ‘hot start’ scenario and early ocean formation on Pluto” Extensional faults (arrows) on the surface of Pluto indicate expansion of the dwarf planet’s icy crust, attributed to freezing of a subsurface ocean. Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute/Alex Parker The accretion of new material during Pluto’s formation may have generated…
“#Planting new forests is part of but not the whole solution to climate change” Credit: CC0 Public Domain The large-scale planting of new forests in previously tree-free areas, a practice known as afforestation, is hailed as an efficient way to remove excess carbon dioxide from the atmosphere—a so-called natural climate solution. But a new study…
“#Research sheds new light on the role of sea ice in controlling atmospheric carbon levels” Credit: Pixabay/CC0 Public Domain A new study has highlighted the crucial role that sea ice across the Southern Ocean played in controlling atmospheric carbon dioxide levels during times of past climate change, and could provide a critical resource for developing…
“#When planting trees threatens the forest” Recently planted pine plantation on Chiloe Island, Chile. Credit: Robert Heilmayr Campaigns to plant huge numbers of trees could backfire, according to a new study that is the first to rigorously analyze the potential effects of subsidies in such schemes. The analysis, published on June 22 in Nature Sustainability,…
“#’Robotic soft matter’ bends, rotates and crawls when hit with light” Northwestern University researchers have developed a family of soft materials that imitates living creatures. When hit with light, the film-thin materials come alive—bending, rotating and even crawling on surfaces. Called “robotic soft matter by the Northwestern team,” the materials move without complex hardware, hydraulics…
“#Studying cells in reduced dimensions” A hairpin loop from a pre-mRNA. Highlighted are the nucleobases (green) and the ribose-phosphate backbone (blue). Note that this is a single strand of RNA that folds back upon itself. Credit: Vossman/ Wikipedia Single-cell RNA sequencing is a powerful tool for identifying transcriptomic variations and developmental trajectories in cell types…
“#A fresh twist in chiral topology” Counting of the topological charge, called the Chern number (C). Strong spin-orbit coupling is induced by heavier elements as indicated by the deeper background color of the pictured elements. Stronger spin-orbit coupling leads to more obvious split Fermi arcs. This allows the number of states crossing the closed loop…
