Coelacanths may live nearly a century, five times longer than researchers expected

Posted: 17 Jun 2021 11:36 AM PDT

Once thought to be extinct, lobe-finned coelacanths are enormous fish that live deep in the ocean. Now, researchers have evidence that, in addition to their impressive size, coelacanths also can live for an impressively long time -- perhaps nearly a century.

'Mosquito smoothie' innovation boosts future malaria vaccine potential

A faster method for collecting pure malaria parasites from infected mosquitos could accelerate the development of new, more potent malaria vaccines.

Novel chirped pulses defy 'conventional wisdom'

Posted: 17 Jun 2021 10:38 AM PDT

Researchers demonstrate highly chirped pulses created by a using a spectral filter in a Kerr resonator, enabling them to widen a laser pulse wavefront by separating the beam's colors. The chirped pulses remain stable even with more than 90% energy loss.

Hubble data confirms galaxies lacking dark matter

The most accurate distance measurement yet of ultra-diffuse galaxy (UDG) NGC1052-DF2 (DF2) confirms beyond any shadow of a doubt that it is lacking in dark matter. The newly measured distance of 22.1 +/-1.2 megaparsecs are based on 40 orbits of NASA's Hubble Space Telescope, with imaging by the Advanced Camera for Surveys and a 'tip of the red giant branch' (TRGB) analysis.

New beetle-dwelling roundworm species discovered in Japan

Posted: 17 Jun 2021 08:55 AM PDT

A new species of nematode (roundworm), named Cryptaphelenchus abietis, was isolated from bark beetles from a dead log collected in Nagano, Japan. The females of this newly described species can be identified based on the size of the post-uterine sac and the conical tail with an elongate posterior part. The males have seven genital papillae and a narrow bursal flap-like extension. The culturability of this species means it may be useful in further nematode research.

Study of young chaotic star system reveals planet formation secrets

Posted: 17 Jun 2021 07:12 AM PDT

Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the young star Elias 2-27 have confirmed that gravitational instabilities play a key role in planet formation, and have for the first time directly measured the mass of protoplanetary disks using gas velocity data, potentially unlocking one of the mysteries of planet formation.

Best strategy to reduce human-bear conflict

Posted: 17 Jun 2021 07:12 AM PDT

Conservationists have long warned of the dangers associated with bears becoming habituated to life in urban areas. Yet, it appears the message hasn't gotten through to everyone. News reports continue to cover seemingly similar situations -- a foraging bear enters a neighbourhood, easily finds high-value food and refuses to leave. The story often ends with conservation officers being forced to euthanize the animal for public safety purposes.

Alpine plant spins its own flavonoid wool

Posted: 17 Jun 2021 07:12 AM PDT

Like the movie version of Spider-Man who shoots spider webs from holes in his wrists, a little alpine plant has been found to eject cobweb-like threads from tiny holes in specialized cells on its leaves. It's these tiny holes that have taken plant scientists by surprise because puncturing the surface of a plant cell would normally cause it to explode like a water balloon.
