Special delivery service: Green hydrogen submarines are on their way
Posted by Chima Wisdom in categories: health, robotics/AI
As Australia turns to nuclear power for its submarines, a UK prototype will test the use of autonomous green hydrogen submarines for freight transport.
A world-first green submarine project will soon get underway after a proposal to power an autonomous underwater vessel with green hydrogen won a share of a United Kingdom £23 million funding program.
Start-up company Oceanways is to build a prototype of a zero emission submarine initially designed to deliver cargo in a twenty-foot container between Glasgow and Belfast.

Lockheed Martin unveils LMXT aerial refueling tanker for the US Air Force
Posted by Chima Wisdom in categories: energy, military
Some improvements of the new model include a significantly improved range, fuel offload capacity, operational and combat-proven advanced camera and vision system, and upgraded communications system. The tanker will have 271,700 pounds (123,241 kg) of fuel capacity – 12,000 kg more than the Airbus A330 MRTT and an almost 20-hour endurance.
“Lockheed Martin has a long and successful track record of producing aircraft for the US Air Force, and we understand the critical role tankers play in ensuring America’s total mission success,” said Greg Ulmer, executive vice president Lockheed Martin Aeronautics. “The LMXT combines proven performance and operator-specific capabilities to meet the Air Force’s refueling requirements in support of America’s National Defense Strategy.”
In addition to better range and increased payload, the LMXT tanker is equipped with a proven fly-by-wire boom currently certified and used by allies to refuel US Air Force receiver aircraft in operations around the world, the world’s first fully automatic boom/air-to-air refueling (A3R) system, and open system architecture JADC2 (Joint All-Domain Command and Control) systems.

Twice the charm: long-lived exotic particle discovered
Posted by Jamal Simpson in category: particle physics
Today, the LHCb experiment at CERN is presenting a new discovery at the European Physical Society Conference on High Energy Physics (EPS-HEP). The new particle discovered by LHCb, labelled as Tcc+, is a tetraquark – an exotic hadron containing two quarks and two antiquarks. It is the longest-lived exotic matter particle ever discovered, and the first to contain two heavy quarks and two light antiquarks.

Quarks are the fundamental building blocks from which matter is constructed. They combine to form hadrons, namely baryons, such as the proton and the neutron, which consist of three quarks, and mesons, which are formed as quark-antiquark pairs. In recent years a number of so-called exotic hadrons – particles with four or five quarks, instead of the conventional two or three — have been found. Today’s discovery is of a particularly unique exotic hadron, an exotic exotic hadron if you like.

DARPA Reveals Successful Hypersonic Cruise Missile Flight Test Has Occurred
Posted by Raphael Ramos in category: military
The Defense Advanced Research Projects Agency has announced the successful free flight test of an air-breathing hypersonic cruise missile demonstrator developed by Raytheon and Northrop Grumman. This comes more than a year after the announcement of successful captive-carry tests of this weapon, as well as a competing design from Lockheed Martin, as part of the Hypersonic Air-breathing Weapon Concept program, or HAWC.
The announcement of this test of the Raytheon/Northrop Grumman missile came earlier today in a press release, but the Defense Advanced Research Projects Agency (DARPA), working together with the U.S. Air Force, conducted it last week. The U.S. Navy was also involved in the test. DARPA’s official statement does not provide any update on any similar progress on the Lockheed Martin design.

Dr Jennifer Garrison, PhD — Global Consortium for Reproductive Longevity & Equality — Buck Institute
Posted by Ira S. Pastor in categories: biotech/medical, chemistry, life extension, neuroscience
Dr. Jennifer Garrison, PhD (http://garrisonlab.com/) is Assistant Professor, Buck Institute for Research on Aging, Founder & Faculty Director, Global Consortium for Reproductive Longevity & Equality (https://www.buckinstitute.org/gcrle/), Assistant Professor in Residence, Cellular and Molecular Pharmacology, UCSF and Adjunct Assistant Professor of Gerontology, USC Leonard Davis School of Gerontology.
Dr. Garrison’s lab is interested in understanding how neuropeptides (a large class of signaling molecules which are secreted from neurons and transmit messages within the brain and across the nervous system) regulate changes in normal and aging animals as well in understanding how they control behavior at both the cell biological and neural circuit level.

What Longevity Diet do Experts Eat?
Posted by J.P. Medved in categories: food, life extension, lifeboat
We interviewed four longevity experts (including several Lifeboat Foundation board members) to learn how they think about their diets. I was particularly struck by how different they all were (except almost all of them fasted)!
Food.
In all our research into longevity so far, from quantifying how we sleep to exploring the science behind whether human life extension is possible, nutrition has remained the most controversial and confusing subject that we’ve covered. For example, when we surveyed 101 of our readers on their longevity diet, we got 101 very different answers. There is little consensus on what the perfect life extension diet should look like.

Chinese KZ-1A returns to flight and lofts new remote sensing satellite into orbit
Posted by Alberto Lao in categories: government, satellites
A Chinese Kuaizhou 1A (KZ-1A) rocket lifted off from the Jiuquan Satellite Launch Center in Inner Mongolia at 06:19 UTC on September 27 lofting a new high-resolution remote sensing satellite into orbit.
The rocket lifted off from Site 95 at Jiuquan, marking the 14th flight of a KZ-1 series rocket. This was also the first KZ-1 launch since the Jilin-1 Gaofen-02C launch in September 2,020 which ended in failure and the loss of its payload.
China’s KZ-1A rocket is manufactured by the ExPace Technology Corporation, an aerospace company owned by the Chinese government, based out of Wuhan in China’s Hubei province. The rocket is capable of delivering payloads of up to 200 kg into a Sun-Synchronous Orbit, and therefore is mainly marketed as a small satellite launch vehicle.
