We summarize the week's scientific breakthroughs every Thursday.
- Animals
Early research asked whether cats dream
Early research asked whether cats dream; researchers still don’t know definitively.
- Genetics
Quicker sepsis diagnosis may be a step closer
Identifying genes linked with sepsis may make it possible to develop a blood test to diagnose the infection days sooner than current methods.
- Genetics
MicroRNAs track radiation doses
MicroRNAs in the blood may indicate radiation damage, a study of mice finds.
- Health & Medicine
Birth-weight boost tied to cleaner air during Beijing Olympics
Babies whose eighth month of gestation fell during the 2008 Beijing Olympics were born slightly heavier than babies born a year earlier or later, a stark indication of the effects of pollution on development.
- Health & Medicine
Too much light slows brown fat, suggesting link with obesity
Brown fat is supposed to be the friendly kind, but making the days longer with artificial light may turn it into an enemy in the battle against obesity.
- Genetics
Molecular scissors snip at cancer’s Achilles’ heel
Finding cancer’s vulnerable spots using CRISPR technology could lead to drugs that hit the disease hard.
- Genetics
Humans and Neandertals mated more recently than thought
Neandertals and humans interbred in Europe until shortly before Neandertals went extinct.
- Health & Medicine
Children’s cells live on in mothers
A baby's cells knit their way into a mother’s body.
- Psychology
On Facebook, you control the slant of the news you choose
Facebook users shield themselves from opposing political ideas more than the site does.
- Health & Medicine
Kids who have had measles are at higher risk of fatal infections
Measles infection leaves kids vulnerable to other infectious diseases for much longer than scientists suspected.
- Astronomy
Wandering planets, the smell of rain and more reader feedback
Readers consider how hard it would be to fashion Paleolithic tools, discuss what to call free-floating worlds and more.
- Neuroscience
Children with autism excel at motion detection test
Children with autism outperform children without the disorder on a test that requires averaging the movements of lots of dots.
