We summarize the week's scientific breakthroughs every Thursday.
- Neuroscience
Alzheimer’s blood tests are getting better, but still have a ways to go
Blood biomarker tests could help doctors know if a person's cognitive symptoms are due to Alzheimer's or something else.
- Animals
Static electricity may help butterflies and moths gather pollen on the fly
Electrostatically charged lepidopterans could draw pollen out of flowers without touching the blooms, computer simulations suggest.
- Health & Medicine
Getting drugs into the brain is hard. Maybe a parasite can do the job
Researchers want to harness the parasite that causes toxoplasmosis to ferry drugs, but some question if the risks can be eliminated.
- Animals
Komodo dragon teeth get their strength from an iron coat
Studying the reptile’s ironclad teeth in more detail could help solve a dinosaur dental mystery.
- Health & Medicine
Some melanoma cancer cells may punch their way through the body
A new study clarifies how melanoma cells use cell membrane protrusions called “blebs” to burrow through tissue.
- Oceans
In a seafloor surprise, metal-rich chunks may generate deep-sea oxygen
Instead of sinking from the surface, some deep-sea oxygen may be created by battery-like nodules that split water into hydrogen and oxygen.
- Oceans
Can bioluminescent ‘milky seas’ be predicted?
For the first time, a scientist has used ocean and atmospheric data to find a milky sea, a huge expanse of luminous water, in past satellite images.
- Neuroscience
Psilocybin temporarily dissolves brain networks
A high dose of the psychedelic drug briefly throws the brain off kilter. Other, longer-lasting changes could hint at psilocybin's therapeutic effects.
- Health & Medicine
Bird flu has been invading the brains of mammals. Here’s why
Although H5N1 and its relatives can cause mild disease in some animals, these viruses are more likely to infect brain tissue than other types of flu.
- Genetics
Freeze-drying turned a woolly mammoth’s DNA into 3-D ‘chromoglass’
A new technique for probing the 3-D structure of ancient DNA may help scientists learn how extinct animals functioned, not just what they looked like.
- Health & Medicine
Breastfeeding should take a toll on bones. A brain hormone may protect them
The hormone CCN3 improves bone strength even as breastfeeding saps bones of calcium, a study in mice shows.
- Animals
Tiny saunas help frogs fight off chytrid fungus
Balmy shelters could bolster resistance to the deadly fungus in amphibian populations, but experts caution they won’t work for all susceptible species.
