A new biography of Benjamin Franklin puts science at the forefront
Likewise, Franklinâs political views were dynamic â 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 cityâs 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...
If an asteroid were heading towards Earth, could you avert disaster?
âIn the real world, we havenât really gotten to this stage where we actually have to design and build missions, so thatâs why we need these exercises,â says NASAâs Paul Chodas, who runs many of the role-plays.
A single enzyme can alter the vibrant colors in parrot plumage
Previous research showed that a different enzyme called PKS makes red aldehyde-based psittacofulvins, says Joseph Corbo, a biologist and neuropathologist at Washington University School of Medicine in St. Louis.
No one is really ‘left-brained’ or ‘right-brained.’ Here’s why
It uses a strong magnetic field to monitor blood flow in the brain as an individual is performing some task (from reading or viewing pictures to thinking about various spoken words).
AI helps driverless cars predict how unseen pedestrians may move
Adding this algorithm to the advanced AI models typically used in autonomous vehicles could help driverless cars make faster and more accurate decisions on the road, even during those unexpected situations they werenât trained to handle.
Why are scientists suddenly interested in UFOs?
Examples of reflective objects include a mirror, a smooth metal can, a car window, a glass bottle, ice, snow or the watery surface of a lake.
Thunderstorms churn up a âboiling potâ of high-energy gamma rays
terrestrial gamma-ray flash: A brief burst of gamma rays, a high-energy type of radiation, that can be produced in Earthâs atmosphere (usually due to thunderstorms).
Boston Dynamics’ robot dog Spot can now ‘play fetch’ â thanks to MIT breakthrough
The researchers achieved this level of granularity with Clio by combining large language models (LLMs) â multiple virtual neural networks that underpin artificial intelligence tools, systems and services â that have been trained to identify all manner of objects, with computer vision.
AI can use tourist photos to help track Antarcticaâs penguins
This transformation of ground photos into a birdâs-eye view allows researchers to track how penguin colonies change in location and population size over time â which could prove especially helpful in remote regions of the world where aerial drone or aircraft surveys are done infrequently.
Using AI, historians track how astronomy ideas spread in the 16th century
âWhen you deal with the scientific revolution, the triumph of the Copernican worldview, we know the big names,â says computational scientist JĂŒrgen Renn of the Max Planck Institute of Geoanthropology in Jena, Germany, who was not involved in the new work.
Lasers reveal Maya city, including thousands of structures, hidden in Mexico
” Consistently, everywhere that this type of job is done, there’s more settlement [found],” Thomas Fort, an archaeologist at the College of Texas at Austin that was not associated with the research study, told Live Scientific research. “It all gives even more pieces for this massive problem, and every problem piece matters.” The following action...
