Traces of fossilised chlorophyll detected inside seriously ancient rocks have shattered records for the oldest sample of an organic pigment by 600 million years. And that pigment was a fetching shade of pink. Not only does the find provide tangible evidence of ancient photosynthesis, analysis of the compounds indicates they were left behind by bacteria,
Visitors to the New York Botanical Garden (NYBG) were in for an incredibly rare treat in June, when its resident corpse flower burst into bloom. And for those of us who couldn’t get there, the garden staff recorded the event in a spectacular timelapse. The corpse flower or titan arum – Amorphophallus titanum (a name
One of the largest icebergs ever documented is still mostly intact one year after it broke off Antarctica, despite losing a big chunk and having its northern flank smashed to bits. The huge ice block, called A68 or A68a, calved from the Larsen C ice shelf in July 2017. It’s hard to say exactly when
Some divers rescuing the boys trapped in a cave in northern Thailand have traversed about 10 miles (16 km) over the past two days.

Astronomers have found the brightest object ever discovered in the early Universe, 13 billion light-years away – a quasar from a time when our Universe was just seven percent of its current age. A quasar is a galaxy that orbits a supermassive black hole actively feeding on material. The light and radio emissions we see are
A man and a woman were found unconscious in Wiltshire, England, on July, after having been exposed to the nerve agent Novichok. This is the same substance that was used to poison the former Russian spy Sergei Skripal and his daughter in March. The second incidence of poisonings has reignited fear and speculation about the
Crows and ravens do not get along. The two corvid species, while very similar to each other, are often at loggerheads. But according to new research, it’s not the larger ravens that are the aggressors. As it turns out, crows – the smaller of the two – are instigating 97 percent of the altercations between
If you’re a vocal science lover, there’s one question we’re pretty sure you’ve been asked at least once: “If we evolved from monkeys, why are there still monkeys?” Most people pause for a second before spilling out the facts on natural selection, common ancestors, and each species adapting to its unique ecosystem. But while that’s
What was your first memory? It’s never a memory of being a baby – most people’s earliest memory is from when they were around three or four years old. But why can we not remember our infant memories? And are they really lost, or just forgotten? A team of neuroscientists from the University of Toronto
When Sudan the white rhino was put down by his carers earlier this year, it confirmed the extinction of one of the savannah’s most iconic subspecies. Despite decades of effort from conservationists, including a fake Tinder profile for the animal dubbed “the most eligible bachelor in the world”, Sudan proved an unwilling mate and died
Elon Musk is testing equipment designed to help rescue the remaining members of a Thai youth soccer team who are trapped in a cave, the Tesla CEO tweeted on Sunday.

Why do many problems in life seem to stubbornly stick around, no matter how hard people work to fix them? It turns out that a quirk in the way human brains process information means that when something becomes rare, we sometimes see it in more places than ever. Think of a “neighborhood watch” made up
As the Ancient Greeks used to say, “Know Thyself.” It probably was meant a little more philosophically that we’re choosing to interpret it, but learning about how your body is put together and why is some seriously fun stuff. We’ve all marvelled at our fingers and toes, wrinkling into prunes in the bath. We’ve all
PAHOA, Hawaii (Reuters) – Dressed in heavy cotton, a helmet and respirator, Jessica Ball worked the night shift monitoring “fissure 8,” which has been spewing fountains of lava as high as a 15-story building from a slope on Hawaii’s Kilauea volcano.

Or perhaps not; maybe nothing lives on any of them, not
In the coming decades, NASA and other space agencies hope to mount some ambitious missions to other planets in our Solar System. In addition to studying Mars and the outer Solar System in greater detail, NASA intends to send a mission to Venus to learn more about the planet’s past. This will include studying Venus’
In the beginning, the solar system was little more than a cloud of dust and gas. Then cold temperatures caused the center of the cloud to collapse, forming the Sun. The newborn star lit up with nuclear fusion, sending light and heat out into the spinning circumstellar disk. Soon that material coalesced into gas planets,
Starting your morning by focusing on the stress to come may harm your mindset throughout the day, according to a new study. The researchers found that when participants woke up feeling like the day ahead would be stressful, their working memory—which helps people learn and retain information even when they’re distracted—was lower later in the
For years, scientists at the Smithsonian Tropical Research Institute in Panama had whispered about the remote island where monkeys used stone tools. A botanist had witnessed the phenomenon during a long-ago survey — but, being more interested in flora than fauna at the time, she couldn’t linger to investigate. A return to the site would
NASA Goddard Space Flight Center A planet that is a candidate for being inhabited will no doubt experience catastrophes and extinction events on it. If life is to survive and thrive on a world, it must possess the right intrinsic and environmental conditions to allow it to be so. While there are hundreds of billions
In June 2017, physicists achieved ‘liquid light’ at room temperature for the first time ever, making this strange form of matter more accessible than ever. This matter is both a superfluid, which has zero friction and viscosity, and a kind of Bose-Einstein condensate - sometimes described as the fifth state of matter – and it allows light to actually flow
When the warmer weather strikes, our gardens and outdoor spaces become a perfect oasis for rest and relaxation. But as nice as the hot weather might be, extreme conditions and record-breaking temperatures can wreak havoc on your plants. There’s of course no question, that when it’s hot, plants will need watering, but knowing when’s the
The Pine Island Glacier is known to be the fastest-melting glacier in Antarctica, responsible for around a quarter of the continent’s ice loss.

Most experts adjusted their projections for the 2018 Atlantic hurricane season because one of the primary formation regions has exhibited cooler than normal sea surface temperatures. There has also been some discussion about whether a potentially emerging El Nino (warmer than normal sea surface temperatures in the eastern Pacific Ocean) will impact activity. Even with
NASA / Cassini-Huygens mission / Imaging Science Subsystem One of the most intriguing, and least resource-intensive, ideas for searching for life in Enceladus’ ocean is to fly a probe through the geyser-like eruption, collecting samples and analyzing them for molecules that are the products of life. Perhaps the greatest quest in science today is to
Solar System exploration isn’t what it used to be. In the old days, various government agencies did all the space exploring. The 12 people who walked on the moon relied on government-run transportation. Now we’re in the era of New Space, and entrepreneurs want to race ahead to the moon and Mars on private spacecraft.
