Forgetting uses more brain power than remembering

Posted: 11 Mar 2019 12:27 PM PDT

Choosing to forget something might take more mental effort than trying to remember it, researchers discovered through neuroimaging.


Teenage T. rex was already chomping on prey

Posted: 11 Mar 2019 11:13 AM PDT

New research indicates that even as a teenager the Tyrannosaurus rex showed signs that it would grow up to be a ferocious predator. Scientists reported evidence that a juvenile T. rex fed on a large plant-eating dinosaur, even though it lacked the bone-crushing abilities it would develop as an adult.


Genes that evolve from scratch expand protein diversity

Posted: 11 Mar 2019 10:31 AM PDT

A new study challenges one of the classic assumptions about how new proteins evolve. The research shows that random, noncoding sections of DNA can quickly evolve to produce new proteins.


Few pathways to an acceptable climate future without immediate action

Posted: 11 Mar 2019 09:53 AM PDT

A new comprehensive study of climate change has painted over 5 million pictures of humanity’s potential future, and few foretell an Earth that has not severely warmed. But with immediate action and some luck, there are pathways to a tolerable climate future, according to a research team.


Mobile devices don’t reduce shared family time

Posted: 11 Mar 2019 09:52 AM PDT

The first study of the impact of digital mobile devices on different aspects of family time in the UK has found that children are spending more time at home with their parents rather than less — but not in shared activities such as watching TV and eating. The increase is in what is called ‘alone-together’ time, when children are at home with their parents but say they are alone.


Palaeolithic art featuring birds and humans discovered

Posted: 11 Mar 2019 09:52 AM PDT

A new article tells how researchers found — in the site of Hort de la Bequera (Margalef de Montsant, Priorat) — an artistic piece from 12,500 years ago in which humans and birds try to interact in a pictorial scene with exceptional traits: figures seem to star a narration on hunting and motherhood.


Ancient records prompt rethink of animal evolution timeline

Posted: 11 Mar 2019 09:51 AM PDT

Scientists are rethinking a major milestone in animal evolution, after gaining fresh insights into how life on Earth diversified millions of years ago.


A robotic leg, born without prior knowledge, learns to walk

Posted: 11 Mar 2019 09:51 AM PDT

Researchers believe they have become the first to create an AI-controlled robotic limb driven by animal-like tendons that can even be tripped up and then recover within the time of the next footfall, a task for which the robot was never explicitly programmed to do.


How to train your robot (to feed you dinner)

Posted: 11 Mar 2019 07:12 AM PDT

Researchers have developed a robotic system that can feed people who need someone to help them eat.


Kepler Space Telescope’s first exoplanet candidate confirmed

Posted: 11 Mar 2019 07:12 AM PDT

An international team of astronomers announced the confirmation of the first exoplanet candidate identified by NASA’s Kepler Mission.


Massive twin star discovered snuggling close to its stellar sibling

Posted: 11 Mar 2019 07:11 AM PDT

Astronomers have discovered a binary star system with the closest high-mass young stellar objects ever measured, providing a valuable ‘laboratory’ to test theories on high mass binary star formation.
