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 ÂŁ23 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 â 12,000 kg more than the Airbus A330 MRTT and an almost 20-hour endurance.
âLockheed 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 Americaâs total mission success,â said Greg Ulmer, executive vice president Lockheed Martin Aeronautics. âThe LMXT combines proven performance and operator-specific capabilities to meet the Air Forceâs refueling requirements in support of Americaâs National Defense Strategy.â
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 worldâs 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 â 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 â particles with four or five quarks, instead of the conventional two or three â have been found. Todayâs 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. DARPAâs official statement does not provide any update on any similar progress on the Lockheed Martin design.

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. Garrisonâs 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.
