We finally have an explanation for 2023’s record-breaking temperatures
But analysis of satellite data by Helge Goessling at the Alfred Wegener Institute in Germany and his colleagues revealed that 2023’s planetary albedo hit a record low.
Extremely rare, black ‘anti-auroras’ paint luminous ‘letter E’ above Alaska
Aurora seeker Todd Salat found the unusual aurora on Nov. 22 over an undefined location in southcentral Alaska at about 4 a.m. regional time (8 a.m. EST). The luminescent letter showed up relatively out of nowhere and lasted for a few mins while biking via several shapes, all of which consisted of unusual dark patches...
Massive, ‘potentially hazardous’ asteroid due to make closest-ever approach to Earth tonight — and you can watch it live
The gigantic space rock, which is taking a trip at about 27,500 miles per hour (44,300 kilometers per hour), will certainly get to a minimal range of 1.37 million miles (2.2 million kilometers) from Earth at 0:27 ET– its closest technique to our planet on document, according to NASA’s Jet Propulsion Research laboratory (JPL). Contact...
Re-engineering where body meets machine
As a Black woman born in West Virginia in 1922, she was a contemporary of the Hidden Figures mathematician Katherine Johnson, and like her peer, Collins contended with both racism and sexism, which impeded her efforts to participate equally in the sciences and in society.
Ancient footprints show how early human species lived side by side
Preserved in a dried-out layer of sand and silt, the team found a trackway consisting of 12 footprints (see image, above), evidently left by one individual walking in a straight line.
A new biography of Benjamin Franklin puts science at the forefront
Likewise, Franklin’s political views were dynamic — he argued forcefully that the colonies should remain loyal to Britain before embracing the calls for independence.
Analyze This: How big was the biggest T. rex?
Or the term can refer to changes that occur as some natural progression within the non-living world (such as computer chips evolving to smaller devices which operate at an ever faster speed).
Robotic pigeon reveals how birds fly without a vertical tail fin
The researchers programmed a computer to control the nine servomotors in Pigeonbot II to steer the craft using propellers on each wing, but also to automatically twist and fan the tail in response, to create the stability that would normally come from a vertical fin.
We’re starting to understand why some people regain weight they lost
That is partly because it is hard to maintain low-calorie diets for a long period of time, though that probably plays a relatively small role, says Laura Catharina Hinte at the Federal Institute of Technology Zurich in Switzerland.
The virus behind an outbreak in Brazil can spread from mother to fetus
A man diagnosed with Oropouche fever this summer still had functional virus in his semen 16 days after his symptoms started, a different group of researchers report in the December Emerging Infectious Diseases.
A huge, ancient Maya city has been found in southern Mexico
Inhabitants living in the many houses surrounded by curved, amphitheater-like residential patios may have enjoyed their time in the nearby lagoon, the researchers speculate, or at the city’s ball court, if they were not at the pyramidal temples taking part in rituals.
Gharial: The prehistoric crocodilian that buzzes and blows bubbles to find a mate
Gharials were once numerous in between Pakistan and Myanmar, with an estimated 5,000 to 10,000 people in the wild in the 1940s. They are now critically threatened as an outcome of searching, environment and fishing loss, with around 650 mature people left. Restricted breeding, nest tracking and other preservation activities helped improve this number from...
