AI is here to stay; it’s time to update your HR policies

Posted by in category: robotics/AI

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.

A potential cure for diabetes found in human stomach cells

Posted by in category: biotech/medical

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.

Stephen Hawking’s last collaborator on physicist’s final theory

Posted by in category: space

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 that aims to turn how science looks at the on its head.

Exclusive: Chandrayaan-3 spacecraft arrives at India’s spaceport in preparation for July launch

Posted by in categories: satellites, security

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.

Researchers develop calcium metal battery with long cycle life

Posted by in categories: energy, materials

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.

Scientists create matter from nothing in groundbreaking experiment

Posted by in categories: cosmology, particle physics, quantum physics

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.

Charismatic Robot Voices: A Boost for Team Creativity?

Posted by in categories: innovation, robotics/AI

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.
