We summarize the week's scientific breakthroughs every Thursday.
- Genetics
Editing human germline cells sparks ethics debate
Human gene editing experiments raise scientific and societal questions.
- Chemistry
Bacteria staining method has long been misexplained
New research upends what scientists know about a classic lab technique, called gram staining, used for more than a century to characterized and classify bacteria.
- Microbes
Possible nearest living relatives to complex life found in seafloor mud
New phylum of sea-bottom archaea microbes could be closest living relatives yet found to the eukaryote domain of complex life that includes people.
- Animals
Ivory listings found on Craigslist as elephant poaching continues
Elephants are hunted by the thousands to meet demand for ivory products.
- 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.
- Neuroscience
Stimulating nerve cells stretches time between thinking, doing
A head zap can stretch the time between intention and action.
- Paleontology
Oldest known avian relative of today’s birds found in China
Fossil find suggests modern birds’ oldest avian relative lived about 6 million years before previous record holder.
- Animals
Stretchy nerves help some big whales open wide
Blue whales and their closest relatives have stretchy nerves near their mouths so they can open wide and swallow a lot of prey.
- Genetics
‘Brainbow’ illuminates cellular connections
A mouse’s optic nerve fluoresces in a rainbow of colors. The image offers a detailed look at nerve-protector cells called oligodendrocytes.
- Genetics
Gene therapy for blindness dims a bit
Gene therapy improves vision temporarily but can’t save sight.
- Neuroscience
Zipping to Mars could badly zap brain nerve cells
Charged particles like the ones astronauts might encounter wallop the brain, mouse study suggests.
- Plants
How slow plants make ridiculous seeds
