The discovery comes from analysis of data from Nasa's Insight lander, which took a seismometer to Mars
Reservoir of liquid water found deep in Martian rocks
WASHINGTON — Scientists have discovered a reservoir of liquid water on Mars — deep in the rocky outer crust of the planet.The findings come from a new analysis of data from Nasa’s Mars Insight Lander, which touched down on the planet back in 2018.The lander carried a seismometer, which recorded four years' of vibrations — Mars quakes — from deep inside the Red Planet.Analyzing those quakes — and exactly how the planet moves — revealed "seismic signals" of liquid water.While there is water frozen at the Martian poles and evidence of vapour in the atmosphere, this is the first time liquid water has been found on the planet.The findings are published in the Proceedings of the National Academy of Sciences.Insight's scientific mission ended in December 2022,...

Horses can plan and strategize, new study shows
LONDON — You can lead a horse to water and, it turns out, convince it to drink if the reward is great enough, researchers have found.A new study has suggested horses are more intelligent than previously thought, having been observed to quickly adapt to a treat-based game with changing rules.Researchers from Nottingham Trent University (NTU) said they were surprised by how the horses quickly grasped the game, busting previous theories that equine brains respond only to immediate stimuli and are not complex enough to strategize.The new findings could lead to more humane horse training regimes and improvements to their welfare, researchers said.The study involved 20 horses, who first were rewarded with a treat for touching a piece of card with their nose.In the second stage, a "stop...

A team of scientists say they found evidence of nutrients they believe created these formations in Gabon
Complex life on Earth may be much older than thought
LIBREVILLE — A group of scientists say they have found new evidence to back up their theory that complex life on Earth may have begun 1.5 billion years earlier than thought.The team, working in Gabon, says they discovered evidence deep within rocks showing environmental conditions for animal life 2.1 billion years ago.But they say the organisms were restricted to an inland sea, did not spread globally and eventually died out.The ideas are a big departure from conventional thinking and not all scientists agree.Most experts believe animal life began around 635 million years ago.The research adds to an ongoing debate over whether so far unexplained formations found in Franceville, Gabon are actually fossils or not.The scientists looked at the rocks around the formations to see if they...

New NASA mission launches to observe ‘invisible universe’ on Earth
WASHINGTON — A revolutionary new satellite that will provide an unprecedented look at Earth’s microscopic marine life and tiny atmospheric particles has launched.The NASA PACE, or Plankton, Aerosol, Cloud, and ocean Ecosystem, mission lifted off at 1:33 a.m. ET Thursday aboard a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station in Florida. The rocket’s booster successfully landed back on Earth about 10 minutes after launch. Just over half an hour after liftoff, the team confirmed that the spacecraft’s solar arrays deployed and it was receiving power.The launch, initially set for Tuesday morning, was delayed twice due to high winds and cumulus clouds. But the weather conditions were more than 95% favorable for launch Thursday morning.Scientists began envisioning a way...

The wings, backbone and legs of the flying reptile were found, but not the skull
Pterosaur: Unique flying reptile soared above Isle of Skye
EDINBURGH — A unique species of flying reptile, or pterosaur, that lived 168-166 million years ago has been discovered on the Isle of Skye.Its wings, shoulders, legs and backbone were found in a rock on a beach, but the fossil's skull was missing.Scientists were surprised to find a pterosaur from this period off Scotland's west coast — they were thought to mostly live in China.The creature — called Ceoptera — is the second pterosaur found on Skye.Its name comes from the Scottish Gaelic word cheò, meaning mist, and is a reference to the Gaelic name of Isle of Syke — Eilean a' Cheò or Isle of Mist.Fossils from this era, called the Middle Jurassic, are extremely rare, says Dr Liz Martin-Silverstone at the University of Bristol who used a CT scanner to make a 3D digital...

The Atlas detector is the size of a tanker and is used to measure some of the smallest objects in the Universe
Huge atom-smasher bid to find missing 95% of Universe
GENEVA — Researchers at the world's biggest particle accelerator in Switzerland have submitted proposals for a new, much larger, supercollider.Its aim is to discover new particles that would revolutionize physics and lead to a more complete understanding of how the Universe works.If approved, it will be three times larger than the current giant machine.But its £12bn price tag has raised some eyebrows, with one critic describing the expenditure as "reckless".That money -- which is only the initial construction cost -- would come from member nations of the European Organization for Nuclear Research (Cern) including the UK, and some experts have questioned whether it makes economic sense.The biggest achievement of the Large Hadron Collider (LHC) was the detection of a new...

Rodney Holbrook says the mouse has been tidying up every night for almost two months
House-proud mouse discovered tidying British man’s shed every night
LONDON — When retired postman Rodney Holbrook set up cameras to try to find out who was tidying his shed almost every night, he found an unexpected helper scurrying around his workbench.The black-and-white, night-vision footage revealed that a tiny mouse was behind the mysterious tidying, helpfully moving objects left on the workbench into a box.“At first I noticed that some food that I was putting out for the birds was ending up in some old shoes I was storing in the shed, so I set up a camera to see what was going on,” Holbrook, who lives in Builth Wells, a small town in central Wales about 60 miles north of the capital city Cardiff, said in a statement.Footage from that camera captured the mouse carrying objects like screwdrivers, clothes pegs or pieces of cable in its mouth and...

Great icebergs, such as the recent A68 object, fertilize' the oceans with mineral nutrients
A23a: World's biggest iceberg on the move after 30 years
LONDON — The world's biggest iceberg is on the move after more than 30 years being stuck to the ocean floor.The iceberg, called A23a, split from the Antarctic coastline in 1986. But it swiftly grounded in the Weddell Sea, becoming, essentially, an ice island.At almost 4,000 sq km (1,500 sq miles) in area, it's more than twice the size of Greater London.The past year has seen it drifting at speed, and the berg is now about to spill beyond Antarctic waters.A23a is a true colossus, and it's not just its width that impresses.This slab of ice is some 400m (1,312 ft) thick. For comparison, the London Shard, the tallest skyscraper in Europe, is a mere 310m tall.A23a was part of a mass outbreak of bergs from the White Continent's Filchner Ice Shelf.At the time, it was hosting a...

Black holes are some of the most powerful and mysterious objects in the known universe
Black holes are lurking much closer to Earth than previously thought
BRUSSELS — The closest black hole to Earth was thought to be 1,560 light-years away -- but a new study suggests there could be one around 150 light-years away.Black holes are some of the most powerful and mysterious objects in the known universe -- and there could be one much closer to Earth than previously thought.A study has found possible evidence of a black hole in the closest open cluster of stars to Earth, called the Hyades cluster.Data from the European Space Agency’s (ESA) Gaia mission revealed the closest known -- and second closest - black holes in 2022, Gaia BH1 and Gaia BH2, which are 1,560 light-years and 3,800 light-years from Earth respectively.A new paper, however, published in the journal Monthly Notices of the Royal Astronomical Society, suggests there could be black...
