Humans rely on a bevy of strange natural chemicals to liven up our food and drink, to endure pain, and to change our perspective. We use caffeine from coffee, tea, and yerba mate to stimulate our bodies and minds, capsaicin from red pepper flakes or isothiocyanates in horseradish or wasabi to enliven our food with spice, and codeine or morphine to endure the pain of injuries and surgeries....

Caviar has never gone out of style, but these days, it’s particularly in demand. In the last year or so, the upmarket delicacy has begun to make regular appearances in over-the-top stunt foods, such as garnishing fried fish sandwiches, and highbrow-lowbrow trendy pairings like caviar-topped Pringles. Market research suggests that U.S. sales are expected to surpass $400 million this...

The globe is speeding to 2.5 to 2.9 degrees Celsius (4.5 to 5.2 degrees Fahrenheit) of global warming since pre-industrial times, set to blow well past the agreed-upon international climate threshold, a United Nations report calculated. To have an even money shot at keeping warming to the 1.5-degree Celsius (2.7 degrees Fahrenheit) limit adopted by the 2015 Paris climate agreement,...

SpaceX launched its mega rocket Starship but lost both the booster and the spacecraft in a pair of explosions minutes into Saturday’s test flight. The rocketship reached space following liftoff from South Texas before communication suddenly was lost. SpaceX officials said it appears the ship’s self-destruct system blew it up over the Gulf of Mexico. [time-brightcove...

[time-brightcove not-tgx=”true”] Revved-up climate change now permeates Americans’ daily lives with harm that is “already far-reaching and worsening across every region of the United States,” a massive new government report says. The National Climate Assessment, which comes out every four to five years, was released Tuesday with details that bring...

The world is off track in its efforts to curb global warming in 41 of 42 important measurements and is even heading in the wrong direction in six crucial ways, a new international report calculates. [time-brightcove not-tgx=”true”] The only bright spot is that global sales of electric passenger vehicles are now on track to match what’s needed — along with many...

BILLINGS, Mont. — Astronaut Frank Borman, who commanded Apollo 8’s historic Christmas 1968 flight that circled the moon 10 times and paved the way for the lunar landing the next year, has died. He was 95. Borman died Tuesday in Billings, Montana, according to NASA. [time-brightcove not-tgx=”true”] Borman also led troubled Eastern Airlines in the 1970s and...

The last 12 months were the hottest earth has ever recorded, according to a new report by Climate Central, a nonprofit science research group. The peer-reviewed report says burning gasoline, coal, natural gas and other fossil fuels that release planet-warming gases like carbon dioxide, and other human activities, caused the unnatural warming from November 2022 to October 2023....

This October was the hottest on record globally, 1.7 degrees Celsius (3.1 degrees Fahrenheit) warmer than the pre-industrial average for the month — and the fifth straight month with such a mark in what will now almost certainly be the warmest year ever recorded. [time-brightcove not-tgx=”true”] October was a whopping 0.4 degrees Celsius (0.7 degrees Fahrenheit) warmer...

Cheetahs are usually daytime hunters, but the speedy big cats will shift their activity toward dawn and dusk hours during warmer weather, a new study finds. Unfortunately for endangered cheetahs, that sets them up for more potential conflicts with mostly nocturnal competing predators such as lions and leopards, say the authors of research published Wednesday in the journal Proceedings of...

LOS ANGELES — Ken Mattingly, an astronaut who is best remembered for his efforts on the ground that helped bring the damaged Apollo 13 spacecraft safely back to Earth, has died, NASA announced. He was 87. “We lost one of our country’s heroes on Oct. 31,” NASA Administrator Bill Nelson said in a statement. [time-brightcove not-tgx=”true”] Thomas...

My closest brush with motherhood was an intense 24 hours fostering an orphaned baby owl monkey in the Peruvian Amazon in 2009. According to Charles Darwin, my maternal drive should have transformed me into an intuitively wise and selfless nurse. But the truth was I felt quite traumatized—fretful, exhausted, and for the sake of my defiled and defecated hair alone (the baby was happiest...

James Hansen first warned Congress of the threat from climate change in 1988. Today, in a controversial new peer-reviewed paper published in Oxford Open Climate Change, he brings a new warning: Scientists are underestimating how fast the planet is warming. And the crisis will have to be met, in part, with geoengineering. [time-brightcove not-tgx=”true”] According to the...

In a little more than five years – sometime in early 2029 – the world will likely be unable to stay below the internationally agreed temperature limit for global warming if it continues to burn fossil fuels at its current rate, a new study says. [time-brightcove not-tgx=”true”] The study moves three years closer the date when the world will eventually hit a...

No matter how much the world cuts back on carbon emissions, a key and sizable chunk of Antarctica is essentially doomed to an “unavoidable” melt, a new study found. [time-brightcove not-tgx=”true”] Though the full melt will take hundreds of years, slowly adding nearly 6 feet (1.8 meters) to sea levels, it will be enough to reshape where and how people live in the...

In the midst of a heat wave in Nova Scotia, Canada, this July, humans sought out air conditioning and shelter in the shade. Fish in the Wrights River, meanwhile, converged on what patches of deeper, cooler water they could find, like holes in the streambed out of the sun’s glare. One of those areas of relief, though, hadn’t occurred naturally. It had been created by humans...

This story was produced in partnership with the Pulitzer Center’s Ocean Reporting Network. Some 13,000 chemicals are associated with plastic production, of which only 7,000 or so have been investigated for their health and environmental impacts. Nearly half of those studied have elements deemed hazardous to human health, but the research—spanning 50 years, multiple languages,...

With warmer oceans serving as fuel, Atlantic hurricanes are now more than twice as likely as before to rapidly intensify from wimpy minor hurricanes to powerful and catastrophic, a study said Thursday.
