If tiny lab-grown 'brains' became conscious, would it still be OK to experiment on them?
A perspective paper published this week argued that brain organoids could soon gain consciousness, and we should consider stricter regulations around them.
Cold snap in Florida made Burmese python puke up a whole deer
Difficulty digesting large meals may limit where these temperature-sensitive snakes can call home — and that might be a good thing in places where they're invasive.
Vast source of rare Earth metal niobium was dragged to the surface when a supercontinent tore apart
Potentially the largest known source of niobium discovered in central Australia formed 830 million years ago, and we can thank the breakup of the ancient supercontinent Rodinia.
Farewell to the computer mouse? Bizarre new designs could reduce wrist injuries, scientists say.
Researchers built two prototype mice, one with a squeezable body and another with a hinged A-frame, in an ergonomic overhaul of the desktop PC staple.
Saturn will be at its biggest and brightest on Sept. 21 — here's how to see it
In a once-a-year event, Saturn is about to reach opposition, with the ringed planet appearing its best and brightest as it approaches its closest point to Earth.

CDC committee votes to change measles vaccine guidance for young children
The Advisory Committee on Immunization Practices has recommended against using the MMRV vaccine in children under 4. This could eliminate a choice for kids' first dose of measles, mumps, rubella and chickenpox prevention.
'Dramatic' changes spotted in first black hole ever imaged
The polarization pattern around M87* — the first black hole to be directly imaged by the Event Horizon Telescope — has changed direction, and scientists aren't sure why.
New report warns that China could overtake the US as top nation in space — and it could happen 'in 5-10 years,' expert claims
A new report from the Commercial Space Federation warns that China could soon overtake the U.S. in the "new space race." The country's rapid progression starkly contrasts the limitations imposed on NASA by record-breaking budget cuts.
Tiny 'brains' grown in the lab could become conscious and feel pain — and we're not ready
Lab-grown brain tissue is too simple to experience consciousness, but as innovation progresses, neuroscientists question whether it's time to revisit the ethics of this line of research.
See the moon, Venus and Regulus in a rare triple conjunction tomorrow
Watch the crescent moon, Venus and the bright star Regulus align in a rare predawn close conjunction tomorrow.
Jaguar in Brazil smashes record for the species' longest documented swim
A jaguar was captured on camera trap on an artificial island near the Serra da Mesa Hydroelectric Power Dam. The only way it could have gotten there was a very long swim.
There's a 90% chance we'll see a black hole explode within a decade, physicists say
How often do black holes explode? New research refines old calculations, hinting that black hole explosions may be a once-in-a-decade occurence.
RFK's handpicked advisers are coming for the childhood vaccine schedule. Here's what to know.
The Advisory Committee on Immunization Practices may vote to disrupt the childhood vaccine schedule, despite what experts say is a lack of evidence to do so.
'There's no shoving that genie back in the bottle': Readers believe it's too late to stop the progression of AI
Over 1,700 readers responded to a Live Science poll, and 46% believe that we must stop AI development now because the risks of it being a threat are too great.
Even brief exposure to air pollution can push the placenta into an inflammatory state, lab study suggests
A study of human placentas suggests that urban air pollution may push the organ's resident immune cells into an inflammatory state.
'Rare' ancestor reveals how huge flightless birds made it to faraway lands
The mystery of how related flightless birds ended up so far apart on different continents may have been solved.
Oldest-known dome-headed dinosaur discovered sticking out of a cliff in Mongolia's Gobi Desert
The juvenile pachycephalosaurs, which predates the previous oldest dome-headed dinosaur by 15 million years, reveals more about how and when this unusual feature developed.
Scientists invent new sunscreen made from pollen
Traditional chemical sunscreens can damage coral reefs. Scientists say there's a fix using one derived from tea plant pollen.
'The sun is slowly waking up': NASA warns that there may be more extreme space weather for decades to come
A new NASA study suggests that solar activity will remain high or rise further in the coming decades, contradicting previous assumptions that the sun was quieting down — and scientists "don't completely understand" why.
