Biological Age Increases With Stress and Is Reversed With Recovery, Study Suggests

A new study in both mice and humans has found that biological age is dynamic, and that some increases in biological age caused by stress can be reversed with recovery. The research is published in Cell Metab olism.

How can we measure age?

Our biological age is not completely linked to our chronological age. While chronological age is a measure of the amount of time you have been alive, biological age indicates how much aging has occurred to your cells over your lifetime.

Hyundai Motor Group announces development of lunar exploration rover

Korean automotive manufacturer “moving beyond land, sea, and air mobility to expand into space”.

Hyundai Motor Group, a leading South Korean automotive manufacturer, has announced its entry into the space exploration industry. On April 20, 2023, the company unveiled plans to build a lunar exploration rover development model, in collaboration with several Korean research institutions in the aerospace sector.

The ambitious project aims to create a versatile mobility platform capable of handling various payloads, with cutting-edge autonomous driving technology, solar charging, thermal management, and radiation shielding features. The rover is designed to carry various pieces of equipment on top of it, with a maximum weight of 70 kg.

The 2023 Ariel Data Challenge: Scientists invite AI experts to help study exoplanets

“Astronomers are struggling to keep up with the complexity and volume of incoming exoplanetary data. The challenge is an excellent platform to facilitate cross-disciplinary solutions with AI experts.”

Fancy winning a ticket to the European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases (ECML-PKDD) or a cash prize? Put forth your technical and artificial intelligence skills to help astronomers understand planets outside our solar system, and you just may.

The Ariel Data Challenge 2023, launched on 14 April, invites experts with an AI or machine learning background from industry and academia.

Study points to new approach to treat chronic transplant rejection

University of Pittsburgh researchers have identified a type of immune cell that drives chronic organ transplant failure in a mouse model of kidney transplantation and uncovered pathways that could be therapeutically targeted to improve patient outcomes. The findings are published in a new Science Immunology paper.

“In solid organ transplantation, such as kidney transplants, one-year outcomes are excellent because we have immunosuppressant drugs that manage the problem of acute rejection,” said co-senior author Fadi Lakkis, M.D., distinguished professor of surgery, professor of immunology and medicine, and scientific director of the Thomas E. Starzl Transplantation Institute at Pitt and UPMC.

“But over time, these organs often start to fail because of a slower form of rejection called chronic rejection, and current medications don’t seem to help. Understanding this problem was the motivation behind our study.”

This 753-Foot Megaship Aims to Be the First Eco-Conscious Luxury Residential Community on the High Seas

If you’re a fan of life on the high seas, this new project will let you travel them year-round in luxe accommodations.

On Tuesday, private residential ship maker Storylines and Croatian shipyard Brodosplit announced they have signed a ship building contract to create what they’re calling the world’s first environmentally conscious residential ship. The 753-foot vessel, dubbed MV Narrative, has begun its engineering phase. The development’s retail value is estimated at $1.5 billion.

This hypersonic hydrogen jet could fly from London to New York in 90 mins

Flying across the world from Europe to Australia currently takes around 20 hours in a regular passenger jet.

But Swiss startup Destinus is looking to slash that time to just four hours — by taking jet travel to hypersonic speeds.

Founded by Russian-born physicist and serial entrepreneur Mikhail Kokorich, Destinus is developing a prototype hydrogen-powered aircraft capable of travelling at Mach 5 and above. That’s five times the speed of sound: over 6,000 kph.
