We summarize the week's scientific breakthroughs every Thursday.
- Animals
Cheap, innovative venom treatments could save tens of thousands of snakebite victims
Momentum is building to finally tackle a neglected health problem that strikes poor, rural communities.
- Health & Medicine
What will happen when COVID-19 and the flu collide this fall?
As the Northern Hemisphere braces for a coronavirus-flu double hit, it’s unclear if it’ll be a deadly combo or one virus will squeeze out the other.
- Environment
What we know and don’t know about wildfire smoke’s health risks
As wildfires become more frequent and severe in California, Oregon and throughout the West Coast, concerns rise about harmful air pollution.
- Microbes
50 years ago, scientists were on the trail of a brain-eating amoeba
In 1970, scientists were studying a brain-eating amoeba that had been implicated in a newfound disease. Today, infections by the parasite are still poorly understood.
- Paleontology
Ancient Lystrosaurus tusks may show the oldest signs of a hibernation-like state
Oddball ancestors of mammals called Lystrosaurus might have slowed way down during polar winters.
- Environment
This moth may outsmart smog by learning to like pollution-altered aromas
In the lab, scientists taught tobacco hawkmoths that a scent changed by ozone is from a favorite flower.
- Agriculture
How does a crop’s environment shape a food’s smell and taste?
Scientific explorations of terroir — the soil, climate and orientation in which crops grow — hint at influences on flavors and aromas.
- Animals
This hummingbird survives cold nights by nearly freezing itself solid
To survive cold Andean nights, the black metaltail saves energy by cooling itself to record-low temperatures, entering a state of suspended animation.
- Animals
Sea butterflies’ shells determine how the snails swim
New aquarium videos show that sea butterflies of various shapes and sizes flutter through water differently.
- Ecosystems
Protecting half the planet could help solve climate change and save species
An analysis lays out where new land protections could complement existing protected areas to achieve various conservation and climate goals.
- Life
This parasitic plant eavesdrops on its host to know when to flower
Dodder plants have no leaves to sense when to bloom, so the parasites rely on a chemical cue from their hosts instead.
- Genetics
Strict new guidelines lay out a path to heritable human gene editing
But scientists say making changes in DNA that can be passed on to future generations still isn’t safe and effective, yet.
