The Flying-V airplane doesn’t look like anything you’ll find at today’s airports, but it could be the future of aviation.
On Tuesday, the CEO of the UK Space Agency Graham Turnock announced the UK would be working more closely with Australia in a “world-first Space Bridge” agreement which will focus on delivering a plane—or rocket, really—to shuttle passengers from continent-to-continent in just four hours. While flights from London to the Big Apple will reportedly take a skerrick over 60 minutes.
It’s all courtesy of a new hypersonic engine SABRE (Synergetic Air-Breathing Rocket Engine)—which the scientists at Reaction Engines are currently developing. Fueled by a combination of hydrogen and oxygen, SABRE is capable of powering a plane to Mach 5.4 (4,000 mph) for speedy commercial travel—that’s around five times the speed of sound—or Mach 25 (19,000 mph) when soaring in space. It’s supposedly greener and cheaper than current air travel, too.

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.
