A great Indian bustard chick was recently conceived through artificial insemination in India's Rajasthan
Indian experts hail breakthrough in bid to save huge native bird
MUMBAI — Last month brought good news for the great Indian bustard, a critically endangered bird found mainly in India.Wildlife officials in the western state of Rajasthan have performed the first successful hatching of a chick through artificial insemination.A lone adult male in one of two breeding centers in Jaisalmer city was trained to produce sperm without mating, which was then used to impregnate an adult female at the second center some 200km (124 miles) away.Officials said the development was important as it has opened up the possibility of creating a sperm bank.Over the years, habitat loss, poaching and collisions with overhead power lines have effected great Indian bustards. Their numbers have fallen from more than 1,000 in the 1960s to around 150 at present.Most of them are...

Ne'Kiya Jackson, left, and Calcea Johnson have published an academic paper detailing how they proved Pythagoras' theorem
Students discover unexpected proof for 2,000-year-old mathematical theory
WASHINGTON — Louisiana students Ne’Kiya Jackson and Calcea Johnson wowed their teachers in 2022 when they discovered a new way to prove the 2000-year-old Pythagorean theorem in response to a bonus question in a high school math contest. But that was only the beginning.A volunteer at their former school, New Orleans’ St. Mary’s Academy, encouraged them to submit their work on the famous mathematical theory to a professional conference, and in March 2023 they became the youngest people to present at the American Mathematical Society’s Southeastern Sectional conference in Atlanta. Their appearance elicited a wave of media coverage, including a spot on “60 Minutes.” The pair also received symbolic keys to the city of New Orleans and a shout-out from Michelle Obama.Now Jackson and...

There are no pictures of the city but it had pyramid temples similar to this one in nearby Calakmul
Researcher finds lost city in Mexico jungle by accident
MEXICO CITY — A huge Mayan city has been discovered centuries after it disappeared under a jungle canopy in Mexico.Archaeologists found pyramids, sports fields, causeways connecting districts and amphitheaters in the southeastern state of Campeche.They found the hidden complex — which they have called Valeriana — using Lidar, a type of radar survey that maps structures buried under vegetation.They believe it is second in size only to Calakmul, thought to be the largest Mayan site in ancient Latin America.The discovery of the city, which is the size of Scotland's capital Edinburgh, was made “by accident” when one archaeologist browsed data on the internet.“I was on something like page 16 of Google search and found a radar survey done by a Mexican organization for...

Lost Silk Road cities discovered in Uzbek mountains
LONDON — Archeologists have found the remains of two medieval cities in the grassy mountains of eastern Uzbekistan, a discovery that could shift our understanding of the fabled Silk Road.Known for the exchange of goods and ideas between the East and West, the trade routes were long believed to have linked lowland cities.But using remote sensing technology, archeologists have now found at least two highland cities that sat along a key crossroad of the trade routes.One of the cities - Tugunbulak, a metropolis spanning at least 120 hectares - sat more than 2,000m (6,600 ft) above sea level, an altitude thought to be inhospitable even today."The history of Central Asia is now changing with this finding," said archaeologist Farhod Maksudov, who was part of the research team.The team...

In a warming Arctic, polar bears are spending more of their time on land
Polar bears face higher risk of disease in a warming Arctic
WASHINGTON — As the Arctic warms, polar bears face a growing risk of contracting viruses, bacteria and parasites that they were less likely to encounter just 30 years ago, research has revealed.In a study that has provided clues about how polar bear disease could be linked to ice loss, scientists examined blood samples from bears in the Chukchi Sea — between Alaska and Russia.They analyzed samples that had been gathered between 1987 and 1994, then collected and studied samples three decades later — between 2008 and 2017.The researchers found that significantly more of the recent blood samples contained chemical signals that bears had been infected with one of five viruses, bacteria or parasites.It is difficult to know, from blood samples, how the bears’ physical health was...

The meteorite was 40-60km in diameter and left a crater 500km across
Mega meteorite tore up seabed and boiled Earth's oceans
LONDON — A huge meteorite first discovered in 2014 caused a tsunami bigger than any in known human history and boiled the oceans, scientists have discovered.The space rock, which was 200 times the size of the one that wiped out the dinosaurs, smashed into Earth when our planet was in its infancy three billion years ago.Carrying sledge hammers, scientists hiked to the impact site in South Africa to chisel off chunks of rock to understand the crash.The team also found evidence that massive asteroid impacts did not bring only destruction to Earth — they helped early life thrive.“We know that after Earth first formed there was still a lot of debris flying around space that would be smashing into Earth,” says Prof Nadja Drabon from Harvard university, lead author of the new...

The supermoon with a partial lunar eclipse was seen around the world - with this picture taken from Jerusalem
Supermoon and lunar eclipse delight stargazers
WASHINGTON — A supermoon has lit up the sky across the world coinciding with a rare partial lunar eclipse.The Moon could be seen to appear brighter and bigger on Tuesday night.Supermoons happen when the Moon is at its closest point to Earth in its orbit.A rare partial lunar eclipse — when the Earth's shadow covers part of the Moon — also happened with about 4% of the Moon's disc covered in darkness.Overnight from Tuesday into Wednesday, the partial lunar eclipse was visible across the globe -- with some of the clearest sightings in the UK and the US.In the UK it occurred between 01:40 BST and 05:47, reaching its peak at 03:44.For those in the US, the eclipse is visible between 20:41 EST and 00:47 - or 22:44 at its maximum.The eclipse was also visible in Latin America, Europe...

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...
