Why are so many robots white?

Problems of racial and gender bias in artificial intelligence algorithms and the data used to train large language models like ChatGPT have drawn the attention of researchers and generated headlines. But these problems also arise in social robots, which have physical bodies modeled on nonthreatening versions of humans or animals and are designed to interact with people.

The aim of the subfield of social robotics called socially assistive robotics is to interact with ever more diverse groups of people. Its practitioners’ noble intention is “to create machines that will best help people help themselves,” writes one of its pioneers, Maja Matarić. The robots are already being used to help people on the autism spectrum, children with special needs and stroke patients who need physical rehabilitation.

The first flowers evolved before bees – so how did they become so dazzling?

Colorful flowers, and the insects and birds that fly among their dazzling displays, are a joy of nature. But how did early relationships between flower colour and animal pollinators emerge?

In a study published in Proceedings of the Royal Society, we have unravelled this mystery by analyzing the visual environments in which the ancestors of today’s bees foraged from flowers.

Intelligence doesn’t make you immune to conspiracy theories – it’s more a thinking style

Over the last two decades, and in particular over the last five years, there has been a growing scientific interest in conspiracy theories and people who believe in them. Although, some may think belief in such stories is linked to intelligence, research is beginning to show that how people think could be more important.

Scientists agree that having a measure of skepticism about official accounts of events is healthy and important, but conspiracy theorising can lead to dangerous consequences for the individual and for society.

SpaceX lines up launch Sunday, pushes Canaveral cargo launch to Tuesday

SpaceX is set to send up another Starlink launch from Kennedy Space Center on Sunday night while prepping for a unique cargo launch from Cape Canaveral now targeting Tuesday.

A Falcon 9 rocket is set to lift off at 6:15 p.m. Eastern from KSC’s Launch Complex 39-A on a southerly trajectory carrying another 23 satellites for the growing internet constellation.

Iran launches three satellites into orbit amid rising tensions with West

Iran on Sunday said it simultaneously launched three satellites into orbit, nearly a week after the launch of a research satellite by the Revolutionary Guards drew Western criticism.

"Three Iranian satellites have been successfully launched into orbit for the first time," state TV reported.

Pennsylvania is the fat dog capital of America

PHILADELPHIA — Ralphie fell in love with lobster at first bite. Steak too.

But the pounds started creeping up. And up. In time, Ralphie’s doctor confirmed what his family already knew: At 30% overweight, the time had come for the South Philly Bullmastiff to go on a serious doggie diet.

Could quantum physics be the key that unlocks the secrets of human behavior?

Human behavior is an enigma that fascinates many scientists. And there has been much discussion over the role of probability in explaining how our minds work.

Probability is a mathematical framework designed to tell us how likely an event is to occur – and works well for many everyday situations. For example, it describes the outcome of a coin toss as ½ – or 50% – because throwing either heads or tails is equally probable.

Hubble finds water vapor in small planet's atmosphere

The Hubble Space Telescope has observed the smallest planet outside our solar system to contain water vapor in its atmosphere, a "landmark discovery" that brings astronomy a step closer to characterizing Earth-like worlds.

At around twice Earth's diameter, planet GJ 9827d orbits a red dwarf star 97 light-years away in the constellation Pisces, NASA and the European Space Agency (ESA) said in statements on Thursday.

‘Abuse’: Politicians are fretting about AI stealing their faces and voices

WASHINGTON — We’re in the midst of the first deepfake election in U.S. history, and, if Congress keeps up at its current pace, expect to be bombarded with disinformation guised as the nation’s politicians.

"Republicans have been trying to push nonpartisan and Democratic voters to participate in their primary,” some New Hampshire voters heard a voice strikingly similar to President Joe Biden saying when they picked up their phone ahead of Tuesday’s primary. “What a bunch of malarkey.”

NASA helicopter's mission ends after three years on Mars

NASA's Ingenuity Mars helicopter, which made history by achieving the first powered flight on another world, has officially ended its nearly three-year mission after sustaining rotor damage during its last outing, the space agency said Thursday.

The tissue-box sized aircraft, which hitched a ride to the Red Planet under the belly of the Perseverance rover, first lifted off the surface on April 19, 2021.

Mixing two types of molecular boron nitride may create a hybrid material

In chemistry, structure is everything. Compounds with the same chemical formula can have different properties depending on the arrangement of the molecules they’re made of. And compounds with a different chemical formula but a similar molecular arrangement can have similar properties.

Graphene and a form of boron nitride called hexagonal boron nitride fall into the latter group. Graphene is made up of carbon atoms. Boron nitride, BN, is composed of boron and nitrogen atoms. While their chemical formulas differ, they have a similar structure – so similar that many chemists call hexagonal boron nitride “white graphene.”

‘Hell chicken’ species suggests dinosaurs weren’t sliding toward extinction

Were dinosaurs already on their way out when an asteroid hit Earth 66 million years ago, ending the Cretaceous, the geologic period that started about 145 million years ago? It’s a question that has vexed paleontologists like us for more than 40 years.

In the late 1970s, debate began about whether dinosaurs were at their peak or in decline before their big extinction. Scientists at that time noted that while dinosaur diversity seemed to have increased in the geologic stage that spanned 83.6 million to 71.2 million years ago, the number of species on the scene seemed to decrease during the last few million years of the Cretaceous. Some researchers have interpreted this pattern to mean that the asteroid that struck the Gulf of Mexico was simply the final blow for an already vulnerable group of animals.
