Scientists uncover the underlying genetics that make flies champion fliers Posted: 18 Mar 2021 11:25 AM PDT Flies have developed excellent flying skills thanks to a set of complicated interactions between numerous genes influencing wing shape, muscle function, and nervous system development, as well as the regulation of gene expression during development.

Scientists uncover warehouse-full of complex molecules never before seen in space Posted: 18 Mar 2021 11:25 AM PDT Scientists have discovered a vast, previously unknown reservoir of new aromatic material in a cold, dark molecular cloud by detecting individual polycyclic aromatic hydrocarbon molecules in the interstellar medium for the first time, and in doing so are beginning to answer a three-decades-old scientific mystery: how and where are these molecules formed in space? The more than a dozen PAHs may hold clues as to the formation of comets, asteroids, stars, and even planets.

How a single cell gives rise to the 37 trillion cells in an average adult Posted: 18 Mar 2021 11:24 AM PDT One of great mysteries of human biology is how a single cell can give rise to the 37 trillion cells contained in the average body, each with its own specialized role. Researchers have devised a way to recreate the earliest stages of cellular development that gives rise to such an amazing diversity of cell types.

Discovery of a 'winged' shark in the Cretaceous seas Posted: 18 Mar 2021 11:24 AM PDT The fossil of an unusual shark specimen reminiscent of manta rays sheds light on morphological diversity in Cretaceous sharks. This plankton feeder was discovered in Mexico and analysed by an international team of palaeontologists.

How bushfire smoke traveled around the world Posted: 18 Mar 2021 11:24 AM PDT Scientists managed to track puzzling January and February 2020 spikes in a measure of particle-laden haze to bushfires, and then uncovered the 'perfect storm' of circumstances that swept the particles emitted from those fires into the upper atmosphere and spread them over the entire Southern Hemisphere.

Enigmatic circling behavior captured in whales, sharks, penguins, and sea turtles Posted: 18 Mar 2021 08:36 AM PDT Technological advances have made it possible for researchers to track the movements of large ocean-dwelling animals in three dimensions with remarkable precision in both time and space. Researchers reporting in the journal iScience on March 18 have now used this biologging technology to find that, for reasons the researchers don't yet understand, green sea turtles, sharks, penguins, and marine mammals all do something rather unusual: swimming in circles.

Hubble shows torrential outflows from infant stars may not stop them from growing Posted: 18 Mar 2021 08:36 AM PDT In this largest-ever survey of nascent stars to date, researchers are finding that gas-clearing by a star's outflow may not be as important in determining its final mass as conventional theories suggest.

Sheep vs. goats: Who are the best problem solvers? Posted: 18 Mar 2021 07:15 AM PDT When it comes to adapting to new situations, goats are a step ahead. Compared to sheep, they can more quickly adapt to changing environmental conditions. The study investigated how well the animals were able to navigate around obstacles to reach food.

Astronomers see a 'space jellyfish' Posted: 18 Mar 2021 07:15 AM PDT A radio telescope located in outback Western Australia has observed a cosmic phenomenon with a striking resemblance to a jellyfish.

Powerful stratospheric winds measured on Jupiter Posted: 18 Mar 2021 06:16 AM PDT Astronomers have now directly measured winds in Jupiter's middle atmosphere. By analyzing the aftermath of a comet collision from the 1990s, the researchers have revealed incredibly powerful winds, with speeds of up to 1450 kilometers an hour, near Jupiter's poles. They could represent a 'unique meteorological beast in our Solar System'.

First images of the cosmic web reveal a myriad of unsuspected dwarf galaxies Posted: 18 Mar 2021 05:56 AM PDT In the universe, galaxies are distributed along extremely tenuous filaments of gas millions of light years long separated by voids, forming the cosmic web. Astronomers have captured an image of several filaments in the early universe, revealing the unexpected presence of billions of dwarf galaxies in the filaments.

Advanced mouse embryos grown outside the uterus Posted: 18 Mar 2021 05:47 AM PDT To observe how a tiny ball of identical cells on its way to becoming a mammalian embryo first attaches to an awaiting uterine wall and then develops into nervous system, heart, stomach and limbs: This has been a highly-sought grail in the field of embryonic development for nearly 100 years. Scientists have now accomplished this feat.

Jupiter's Great Red Spot feeds on smaller storms Posted: 17 Mar 2021 12:51 PM PDT The stormy, centuries-old maelstrom of Jupiter's Great Red Spot was shaken but not destroyed by a series of anticyclones that crashed into it over the past few years, according to a new study.

Scientists develop device to 'communicate' with plants using electrical signals Posted: 16 Mar 2021 08:22 AM PDT Scientists have developed a device that can deliver electrical signals to and from plants, opening the door to new technologies that make use of plants.
