Research reveals fruit fly circadian clock mechanisms

The higher the temperatures, the faster physiological processes are. But there is an exception: the so-called circadian clock, which regulates the sleep-wake cycle in organisms. A fascinating question for scientists is why the inner clock runs in an almost unchanging way despite fluctuations in temperatures. This is a phenomenon known as temperature compensation. Studies indicate that different molecular mechanisms contribute to this. from Phys.org - latest science and technology news stories https://ift.tt/QC0hbzS

Functional analyses of RNA-related enzymes using a next-generation DNA sequencer

Genetic information encoded in genomic DNA is transcribed to mRNAs and then the codons on mRNA are decoded by transfer RNAs (tRNAs) during protein synthesis. tRNAs deliver amino acids to ribosomes and proteins are synthesized from the amino acids on the ribosomes according to the decoded genetic information.

Palau's Rock Islands harbor heat-resistant corals

Ocean warming is driving an increase in the frequency and severity of marine heatwaves, causing untold damage to coral reefs. Tropical corals, which live in symbiosis with tiny single celled algae, are sensitive to high temperatures, and exhibit a stress response called bleaching when the ocean gets too hot. In the last 4 decades, marine heatwaves have caused widespread bleaching, and killed millions of corals. Because of this, a global search is underway for reefs that can withstand the heat stress, survive future warming, and act as sources of heat-tolerant coral larvae to replenish affected areas both naturally and through restoration. from Latest Science News -- ScienceDaily https://ift.tt/K9qWHBG

Astronomers report most distant known galaxies, detected and confirmed

Astronomers have discovered the earliest and most distant galaxies confirmed to date using data from the James Webb Space Telescope. The telescope captured light emitted by these galaxies more than 13.4 billion years ago, which means the galaxies date back to less than 400 million years after the Big Bang, when the universe was only 2 percent of its current age. from Latest Science News -- ScienceDaily https://ift.tt/4pvoU6d

Ankylosaurs battled each other as much as they fought off T. rex

Scientists have found new evidence for how armored dinosaurs used their iconic tail clubs. The exceptional fossil of the ankylosaur Zuul crurivastator has spikes along its flanks that were broken and re-healed while the dinosaur was alive -- injuries that the scientists think were caused from a strike by another Zuul's massive tail club. This suggests ankylosaurs had complex behavior, possibly battling for social and territorial dominance or even engaging in a 'rutting' season for mates. from Latest Science News -- ScienceDaily https://ift.tt/my79sY2

Countries bet on forests and soils to reach net-zero

New research highlights the risks of countries relying on nature-based solutions to achieve net-zero. National climate strategies set out how countries plan to reduce emissions, for example by phasing out fossil-fuel use, to get to net-zero in 2050. The study found, once the bulk of emissions have been reduced, countries plan to 'cancel out' the left-over difficult to decarbonise emissions, such as those from agriculture, by using forests and soils to remove carbon from the atmosphere. from Latest Science News -- ScienceDaily https://ift.tt/Gsyhr6v

Tiny underwater sand dunes may shed light on larger terrestrial and Martian formations

Researchers have been studying the dynamics of how crescent-shaped sand dunes are formed.
