A 2016 satellite photo shows Hurricane Madeline and Hurricane Lester heading straight toward Hawaii's Big Island. When viewed from above, the twin cyclones and the surrounding clouds look eerily like a giant smiley face.
For the first time, researchers have identified a new type of landslide of permafrost in Canada's Northwest Territories.
Plants can't easily pick up and move when environmental conditions get rough, so they've evolved strategies to weather harsh conditions in place. That could help some plants survive in the face of a warming climate.

Colorectal cancer in young people shows genetic and structural differences that may make it more aggressive and treatment-resistant than the cancer tends to be in older people.
A new study with data from mice and human tissues suggests that, in ulcerative colitis, immune cells in the gut might make pain-sensing nerves hypersensitive.
A woman's unexplained abdominal pain led doctors to a diagnosis that has only been documented a few hundred times over the past 400 years.
A proposed shift in recommendations for hepatitis B vaccination in the U.S. could leave millions of young adults unprotected, a new modeling study suggests.
In his new book, "Liars, Cheats and Copycats," biologist James O'Hanlon surveys deception across the animal kingdom and asks whether any of it adds up to lying.

The PBS Nature film "Tiger Island" captures rare glimpses of tiger behavior, including a mother, father and cubs spending time together — a first for these usually solitary cats.
Live Science spoke with comparative psychologist Christian Frings to discuss a new theory for why orcas are attacking yachts.
Carrion crows made decisions about their visual environments significantly faster than humans and primates tend to, according to a comparison in a new study.
Researchers filmed dwarf reed snakes (Pseudorabdion) from different angles to better understand how the serpents pull off their remarkable rolling behavior.
A new study revealed that people who rely on AI for basic tasks become less motivated over time. Live Science polled its readers on whether they have experienced this situation.

The promise of AI automation to fix the administrative problems facing universities is a fallacy. These systems will only increase the burdens of already-struggling institutions.
A new study revealed that people who rely on AI for basic tasks like math problems became less motivated over time. In response, Live Science polled its readers to see if they agree with these findings.
In a set of problem-solving experiments, researchers found that people who used AI to get answers were more likely to give up and fail when that help was removed, compared with people who did not use AI.
AI companies know they are being held hostage by each other, and that they need to take action to self-regulate before they suffer major reputational and legal consequences. There is a blueprint on how they can do it.
