Alternative splicing linked to mammal lifespan (English, Level A1)

Researchers published a new study in Nature Communications journal.
They study alternative splicing in mammals.
They compare 26 different mammal species.
The species live from 2.2 to 37 years.
Alternative splicing makes many different proteins.
Splicing predicts lifespan better than gene activity.
They also study six tissues, including the brain.
The brain shows twice as many events.
Many RNA-binding proteins control splicing.
The work finds new targets for healthy aging.

Mosquitoes can learn to like DEET smell

A study finds that mosquitoes can learn to associate the smell of DEET with food and in some cases become attracted to it. The research suggests how people should use repellents like DEET.

Metal tubes that do not sink

Researchers developed treated metal tubes whose inner surface traps air and stays dry, so the tubes float even in rough water. The design could lead to floating rafts for ships, buoys and wave energy devices.

How cowbirds make a watery song

Researchers explain how brown-headed cowbirds make a watery timbre by switching between the two sides of the syrinx and by controlled breathing. Starlings raised with cowbirds learned to copy the sounds.
