Scientists recover proteins from a 24 million-year-old rhino fossil
LONDON — Scientists have recovered ancient proteins from a fossilized rhinoceros tooth, breaking new ground in the study of ancient life on Earth.The 24-million-year-old tooth, which was unearthed in the Canadian Arctic, contains proteins that are 10 times older than the most ancient known DNA. Using the sample, scientists have now analyzed the oldest detailed protein sequence on record.“Enamel is so hard it protects these proteins over deep time (long time scales),” said Ryan Sinclair Paterson, a postdoctoral researcher at the Globe Institute at the University of Copenhagen in Denmark who led the Canadian research. “It’s essentially like a vault. What we did was unlock this vault, at least for this specific fossil.”The study of ancient DNA preserved in bones, fossils and dirt...

Moths layed eggs on plants based on the sounds they made, which indicated their health
Animals react to secret sounds from plants, say scientists
TEL AVIV — Animals react to sounds being made by plants, new research suggests, opening up the possibility that an invisible ecosystem might exist between them.In the first ever such evidence, a team at Tel Aviv University found that female moths avoided laying their eggs on tomato plants if they made noises they associated with distress, indicating that they may be unhealthy.The team was the first to show two years ago that plants scream when they are distressed or unhealthy.The sounds are outside the range of human hearing, but can be perceived by many insects, bats and some mammals."This is the first demonstration ever of an animal responding to sounds produced by a plant," said Prof Yossi Yovel of Tel Aviv University."This is speculation at this stage, but it could be...

The Virtual Telescope Project captured an image of the object on Wednesday
Astronomers spot an interstellar object zipping through our solar system
PASADENA, California — A newly discovered object speeding through our solar system is sparking excitement among astronomers because it’s not from around here. Believed to be a comet, the object is only the third celestial body from beyond our solar system ever to be observed in our corner of the universe.This interstellar visitor, now officially named 3I/ATLAS, became known when the NASA-funded ATLAS (Asteroid Terrestrial-impact Last Alert System) telescope in Chile reported spotting it on Tuesday. Since then, astronomers reviewing archival observations from multiple telescopes have tracked the object’s movements as far back as June 14 and found that the comet arrived from the direction of the Sagittarius constellation.The comet’s speed and path through the solar system are two...

The boomerang was found near stones, animal and human bones
World's oldest boomerang doesn't actually come back
WARSAW — The world's oldest boomerang is older than previously thought, casting new light on the ingenuity of humans living at the time.The tool, which was found in a cave in Poland in 1985, is now thought to be 40,000 years old.Archaeologists say it was fashioned from a mammoth's tusk with an astonishing level of skill.Researchers worked out from its shape that it would have flown when thrown, but would not have come back to the thrower.It was probably used in hunting, though it might have had cultural or artistic value, perhaps being used in some kind of ritual.The mammoth ivory boomerang was unearthed in Oblazowa Cave in southern Poland.It was originally thought to be about 30,000 years old. But new, more reliable radiocarbon dating of human and animal bones found at the site...

Two European satellites mimic total solar eclipse as scientists aim to study corona
PARIS — A pair of European satellites have created the first artificial solar eclipse by flying in precise formation, providing hours of on-demand totality for scientists.The European Space Agency released the eclipse pictures at the Paris Air Show on Monday.Launched late last year, the orbiting duo have churned out simulated solar eclipses since March while zooming tens of thousands of kilometers above Earth.Flying 150 meters apart, one satellite blocks the sun like the moon does during a natural total solar eclipse as the other aims its telescope at the corona, the sun's outer atmosphere that forms a crown or halo of light.It's an intricate, prolonged dance requiring extreme precision by the cube-shaped spacecraft, less than 1.5 meters in size.Their flying accuracy needs to be...

A vast cavern in South Dakota shielded from the outside world will house sensitive equipment to detect tiny changes in sub-atomic particles
Scientists in a race to discover why our Universe exists
WASHINGTON — Inside a laboratory nestled above the mist of the forests of South Dakota, scientists are searching for the answer to one of science's biggest questions: why does our Universe exist?They are in a race for the answer with a separate team of Japanese scientists – who are several years ahead.The current theory of how the Universe came into being can't explain the existence of the planets, stars and galaxies we see around us. Both teams are building detectors that study a sub-atomic particle called a neutrino in the hope of finding answers.The US-led international collaboration is hoping the answer lies deep underground, in the aptly named Deep Underground Neutrino Experiment (Dune).The scientists will travel 1,500 meters below the surface into three vast underground...

Pipestone Creek still holds many secrets
Scientists try to solve mystery of mass dinosaur grave beneath lush Canadian forest
ALBERTA, Canada — Hidden beneath the slopes of a lush forest in Alberta, Canada, is a mass grave on a monumental scale.Thousands of dinosaurs were buried here, killed in an instant on a day of utter devastation.Now, a group of paleontologists have come to Pipestone Creek — appropriately nicknamed the "River of Death" — to help solve a 72-million-year-old enigma: how did they die?Trying to work out exactly what happened here starts with the hefty strike of a sledgehammer.Brute force is needed to crack open the thick layer of rock that covers what Professor Emily Bamforth, who's leading the dig, describes as "paleo gold".As her team begins the more delicate job of removing the layers of dirt and dust, a jumble of fossilized bones slowly begins to...

Attenborough at 99 delivers 'greatest message he's ever told'
LONDON — Sir David Attenborough is launching what he says is one of the most important films of his career as he enters his hundredth year. He believes his new, cinema-length film Ocean could play a decisive role in saving biodiversity and protecting the planet from climate change. Sir David, who will be 99 on Thursday, says: "After almost 100 years on the planet, I now understand the most important place on Earth is not on land, but at sea." The ocean is the planet's support system and humanity's greatest ally against climate catastrophe, the film argues. It shows how the world's oceans are at a crossroads. A blue carpet will be rolled out at the film's premiere tonight at the Royal Festival Hall. A host of celebrities are expected to attend...

Artwork of K2-18b, a faraway world that may be home to life
Scientists find promising hints of life on distant planet
LONDON — Scientists have found new but tentative evidence that a faraway world orbiting another star may be home to life.A Cambridge team studying the atmosphere of a planet called K2-18b has detected signs of molecules which on Earth are only produced by simple organisms.This is the second, and more promising, time chemicals associated with life have been detected in the planet's atmosphere by Nasa's James Webb Space Telescope (JWST).But the team and independent astronomers stress that more data is needed to confirm these results.The lead researcher, Prof Nikku Madhusudhan, told me at his lab at Cambridge University's Institute of Astronomy that he hopes to obtain the clinching evidence soon."This is the strongest evidence yet there is possibly life out there. I can...

Titanic scan reveals ground-breaking details of ship's final hours
LONDON — A detailed analysis of a full-sized digital scan of the Titanic has revealed new insight into the doomed liner's final hours.The exact 3D replica shows the violence of how the ship ripped in two as it sank after hitting an iceberg in 1912 — 1,500 people lost their lives in the disaster.The scan provides a new view of a boiler room, confirming eye-witness accounts that engineers worked right to the end to keep the ship's lights on.And a computer simulation also suggests that punctures in the hull the size of A4 pieces of paper led to the ship's demise."Titanic is the last surviving eyewitness to the disaster, and she still has stories to tell," said Parks Stephenson, a Titanic analyst.The scan has been studied for a new documentary by National Geographic...
