| How do clownfish earn their stripes? Posted: 24 May 2021 01:18 PM PDT Clownfish are instantly recognizable by their white stripes, which appear as they mature from larvae into adults. But how these distinctive patterns form has long remained a mystery. Now, a new study has found that the speed at which these white bars form depends on the species of sea anemone in which the clownfish live. The scientists also discovered that thyroid hormones, which play a key role in metamorphosis, drive how quickly their stripes appear. |
| 36 dwarf galaxies had simultaneous 'baby boom' of new stars Posted: 24 May 2021 08:02 AM PDT Three dozen dwarf galaxies far from each other had a simultaneous 'baby boom' of new stars, an unexpected discovery that challenges current theories on how galaxies grow and may enhance our understanding of the universe. |
| New fishing tech may pose risks to fisheries Posted: 24 May 2021 08:01 AM PDT New developments in recreational fishing technology -- from the use of aerial drones and social media scouting reports to advances in hook design -- are creating challenges for fisheries management and effective policy making, according to a new study. |
| Plasma jets reveal magnetic fields far, far away Posted: 24 May 2021 06:20 AM PDT For the first time, researchers have observed plasma jets interacting with magnetic fields in a massive galaxy cluster 600 million light years away, thanks to the help of radio telescopes and supercomputer simulations. The findings can help clarify how such galaxy clusters evolve. |
| Dental crowding: Ancient baleen whales had a mouth full Posted: 24 May 2021 06:19 AM PDT CT scans of a 25 million year-old fossil skull show the Aetiocetus weltoni had both teeth and baleen, unlike modern whales. |
| Implantable piezoelectric polymer improves controlled release of drugs Posted: 24 May 2021 06:19 AM PDT A membrane made from threads of a polymer commonly used in vascular sutures can be loaded with therapeutic drugs and implanted in the body, where mechanical forces activate the polymer's electric potential and slowly release the drugs. The novel system overcomes the biggest limitations of conventional drug administration and some controlled release methods, and could improve treatment of cancer and other chronic diseases. |
| Telling up from down: How marine flatworms learn to sense gravity Posted: 21 May 2021 06:44 AM PDT All life forms are endowed with the ability to sense gravity. However, the mechanism is not well-understood in acoels, a group of marine flatworms that represent a primitive invertebrate (without backbone) lifeform. In a new study, zoologists suggest necessary conditions for this ability to develop in hatchlings of an acoel species native to Okayama sea coasts, opening doors to understanding evolution better and pathology treatment applications in humans. |
