Synthetic tissue can repair hearts, muscles, and vocal cords

Posted: 30 Nov 2021 12:04 PM PST

Combining knowledge of chemistry, physics, biology, and engineering, scientists from McGill University develop a biomaterial tough enough to repair the heart, muscles, and vocal cords, representing a major advance in regenerative medicine.

Researchers model circadian clock neurons in a day-active animal

Posted: 30 Nov 2021 05:42 AM PST

It's no secret that jet lag and night-shift work can wreak havoc on the way our body's internal clock syncs up our daily wake-sleep cycle, known as circadian rhythm, but now researchers say they are a step closer to understanding how the brain creates behavioral rhythms optimized for diurnal, rather than nocturnal, life.

Using a new microspectroscopic technique, scientists have found that steam disinfection of silicone-rubber baby bottle nipples exposes babies and the environment to micro- and nanoplastic particles.

Challenges to ongoing clean-up of burnt and unburnt nurdles along Sri Lanka’s coastline

Posted: 29 Nov 2021 12:50 PM PST

When a fire broke out on the deck of the M/V XPress Pearl cargo ship on May 20, 2021, an estimated 70-75 billion pellets of preproduction plastic material, known as nurdles, spilled into the ocean and along the Sri Lankan coastline. That spill of about 1,500 tons of nurdles, many of which were burnt by the fire, has threatened marine life and poses a complex clean-up challenge.

Unveiling the hidden cellular logistics of memory storage in neurons

Posted: 24 Nov 2021 02:21 PM PST

Exploring the mechanisms involved in sleep-dependent memory storage, a team of cellular biologists found that RNAs associated with an understudied cell compartment in hippocampal neurons vary greatly between sleeping and sleep-deprived mice after learning.
