In 2006, NASA’s Mars Reconnaissance Orbiter (MRO) established orbit around the Red Planet. Using an advanced suite of scientific instruments – which include cameras, spectrometers, and radar – this spacecraft has been analyzing landforms, geology, minerals and ice on Mars for years and assisting with other missions.   While the mission was only meant to

Three out of four pediatricians disapprove of spanking, research finds. The survey of pediatricians around the US finds that most think spanking seldom or never results in positive outcomes for kids.   Catherine Taylor, an associate professor of Global Community Health and Behavioral Sciences at Tulane University School of Public Health and Tropical Medicine, surveyed

A new map shows thousands of shipwrecks scattered around Ireland since the 16th century – and it shows how many maritime disasters are still a total mystery. The “Wreck Viewer,” released by the Irish government’s National Monuments Service this April, shows the approximate locations of 3,554 shipwrecks across a 355,000 square mile area around Ireland and

The universe that Stephen Hawking spent a lifetime studying now knows his voice. Following Hawking’s death in March, the renowned British physicist, who had battled a debilitating degenerative motor neuron disease for decades, was remembered at a memorial service Friday at Westminster Abbey.    His ashes were buried between Charles Darwin and Isaac Newton and later covered with a gravestone — etched with an equation he used

It’s called MAD. The notion that Mutually Assured Destruction would be inescapable if one nuclear superpower were to unleash its deadly arsenal against another. The reasoning is that by launching a first strike against any nuke-toting enemy, the aggressor would inevitably provoke an automatic counter-attack – ensuring mutual, fiery annihilation. But aside from this fatal

Scientists have collected the most detailed recordings of narwhals to date, displaying a charming range of click, squeak, and buzz vocalisations that will help researchers understand these ‘sea unicorns’ like never before.   This information could help scientists predict how the East Greenland narwhals might be affected by an increase in human-made sounds in their

The most complete analysis to date measuring ice sheet changes in Antarctica reveals Earth’s southernmost continent has lost some 3 trillion tonnes of ice over the past quarter-century.   A collective effort by over 80 scientists across the world used satellite data to determine estimates of ice-sheet mass balance between 1992 and 2017, ultimately calculating

Scientists have created the most extensive brain map to date of a person with an extremely rare form of blindness. To Milena Canning, objects are invisible – unless they are moving.   Canning, who is 48 and hails from Scotland, wasn’t born blind. She was left without sight 18 years ago after a respiratory infection,

Particles collected from Earth’s upper atmosphere, originally deposited by comets, are older than our Solar System, scientists say – and these fine bits of interstellar dust could teach us about how planets and stars form from the very beginning.   These cosmic particles have lived through at least 4.6 billion years and travelled across incredible

The source of a mysterious microwave glow detected across our galaxy eluded astronomers for decades. But now a crack team has finally pinpointed the source: nanoscopic particles of crystalline carbon, otherwise known as diamond dust.   There are several environments across the Milky Way that produce a faint glow known as anomalous microwave emission (AME).

For centuries – millennia even – they’ve towered over the savannah like giants from another world, but their long, almost immortal watch is at last beginning to fade. The African baobab, the largest and longest-living tree among all angiosperm (flowering) plants, is in the midst of a deadly crisis, with new research finding several of
