The widespread use of advanced artificial intelligence tools like ChatGPT means the rapidly developing technology is being used in workplaces across the country whether employers are aware of it or not.

So, for companies that have not yet developed ground rules for AI use, you’re being put on alert: It’s time to update your employee handbook, an human resources expert says.

Jennifer Morehead, owner and CEO of Flex HR, which handles outsourced human resources services for major firms like Harley-Davidson and Kimberly Clark, says there are an array of issues AI firms need to consider now that the tools are becoming increasingly accessible in the workplace.

The ability to acquire gut stem cells via biopsy and have a significant proliferative capacity in culture make them an invaluable resource for autologous cell treatments. In the mouse gut, insulin-producing cells can be produced. Still, human gut tissues have not been able to produce an abundance or durability of insulin-secreting cells to assess their potential as a cell treatment for diabetes.

In a new study, scientists from Weill Cornell Medicine showed that stem cells from human stomach can be converted into insulin-secreting cells. Scientists demonstrated that they could obtain the stem cells from the human stomach and reprogram them directly—with strikingly high efficiency—into cells that closely resemble pancreatic insulin-secreting cells known as beta cells.

In experiments on a mouse model, this approach reversed disease signs. According to scientists, the study offers a promising approach, based on patient’s cells, for type 1 diabetes and severe type 2 diabetes.

When Thomas Hertog was first summoned to Stephen Hawking’s office in the late 1990s, there was an instant connection between the young Belgian researcher and the legendary British theoretical physicist.

“Something clicked between us,” Hertog said.

That connection would continue even as Hawking’s debilitating disease ALS robbed him of his last ways to communicate, allowing the pair to complete a new theory that aims to turn how science looks at the universe on its head.

The spacecraft that the Indian Space Research Organization (ISRO) hopes to land on the moon later this year, has been wheeled into the country’s spaceport, Satish Dhawan Space Centre, WION has learnt.

Named as Chandrayaan-3 (Sanskrit for Moon Vehicle-3), this will be India’s third lunar mission and will attempt both controlled soft-landing on the lunar surface and in-situ analysis by the means of a rover.

In the evening hours on Friday, the slow-moving, specialised truck ferrying the spacecraft from UR Rao Satellite Centre in Bengaluru arrived at India’s spaceport, under a security blanket.

The chain says it’s trying to speed up the drive-thru to squeeze in a few extra sales each day.

As potential alternatives to lithium-ion batteries, rechargeable calcium (Ca) metal batteries offer advantageous features such as high energy density, cost-effectiveness, and natural elemental abundance. Its properties are also thought to help accelerate ion transport and diffusion in electrolytes and cathode materials, giving it an edge over other lithium-ion battery alternatives such as magnesium and zinc.

However, many challenges impede the development of practical Ca metal batteries. The challenges include the lack of an efficient electrolyte and the absence of cathode materials with sufficient Ca²⁺ storage capabilities.

Now, Tohoku University researchers have developed a prototype calcium metal rechargeable battery capable of 500 cycles of repeated charge-discharge – the benchmark for practical use.

We’ve probably all heard the phrase you can’t make something from nothing. But in reality, the physics of our universe isn’t that cut and dry. In fact, scientists have spent decades trying to force matter from absolutely nothing. And now, they’ve managed to prove that a theory first shared 70 years ago was correct, and we really can create matter out of absolutely nothing.

The universe is made up of several conservation laws. These laws govern energy, charge, momentum, and so on down the list. In the quest to fully understand these laws, scientists have spent decades trying to figure out how to create matter – a feat that is far more complex than it even sounds. We’ve previously turned matter invisible, but creating it out of nothing is another thing altogether.

There are many theories on how to create matter from nothing – especially as quantum physicists have tried to better understand the Big Bang and what could have caused it. We know that colliding two particles in empty space can sometimes cause additional particles to emerge. There are even theories that a strong enough electromagnetic field could create matter and antimatter out of nothing itself.

Summary: Robotic voices with a charismatic tone can positively influence the creative performance of teams.

Researchers designed a social robot’s speech to sound charismatic, employing a confident, passionate tone and tested its effects on students during a creativity task.

The results revealed students were more innovative when the robot used a charismatic tone, leading to more original and elaborate ideas.

The psychedelic substances 5-MeO-DMT causes a long-lasting increase in the number of tiny protrusions called dendritic spines in the brain, according to new research published in Neuropsychopharmacology. The study, which was conducted on mice, sheds light on the behavioral and neural mechanisms of 5-MeO-DMT.

Serotonergic psychedelics (such as psilocybin and LSD) have shown promise as potential therapeutics for mental illnesses like depression and anxiety. Short-acting compounds are particularly interesting because they require less dosing time, which could improve patient access to treatment. In humans, 5-MeO-DMT produces a short-lasting experience due to its rapid breakdown in the body.

“My lab started research on psychiatric drugs like ketamine and psychedelics about 10 years ago. We were motivated by how basic science and clinical research can together powerfully move a drug forward to become medicine. Specifically I believe there is a lot of potential for psychedelics as therapeutics, and that drives our interest in this topic,” said study author Alex Kwan (@kwanalexc), an associate professor in the Meinig School of Biomedical Engineering at Cornell University.
