‘Recycling’ Energy Seen Saving Companies Money

Posted by in categories: economics, energy, sustainability

A Chicago-based entrepreneur says many industrial power users can save money, get more electricity, and reduce greenhouse gas emissions by using the energy they already consume more efficiently. It’s called recycling energy — capturing waste heat and turning it into power.

New Metamaterial Transmits Light With No Energy Loss

Posted by in categories: computing, mobile phones, space

Very soon we might be able to say good riddance to the overheating laptops, phones and tablets that we deal with every day. Electrons carry information around circuits but lose energy as heat during transmission. Electrons are the best thing we have right now for computing, but in the near future we could wave goodbye to electronics and welcome photon, or light, communication that will be both faster and cooler. There are still few hurdles before we can get this technology in every home and every pocket, but one of its limitations was just solved by the development of a new metamaterial.

A metamaterial is a substance that has properties not observed in nature. In this case, the special property is its refractive index, a value that describes how light propagates through a medium. Take water or glass, for example, which cause light rays to bend as they travel through them. This is why pools always look shallower than they actually are.

The new metamaterial has a refractive index of zero, which means that the light phase in the material can travel infinitely fast. This doesn’t mean that relativity is violated by this material, though. Light has a “group velocity,” the velocity at which the wave propagates into space, and a “phase velocity,” the velocity at which the peaks of the waves move with respect to the wave.

NASA’s “nearly silent” supersonic X-Plane goes into production

Posted by in category: transportation

NASA has started production of a plane that will fly faster than the speed of sound, but will be almost inaudible from the ground below.

The US space agency plans to bring supersonic speeds back to commercial air travel with the X-Plane. But unlike its predecessor Concorde, its sonic booms will be too soft to be noticed from the ground.

X-59 QueSST

Posted by in category: transportation

In partnership with NASA, the Lockheed Martin Skunk Works team is solving one of the most persistent challenges of supersonic flight – the sonic boom. NASA awarded Lockheed Martin Skunk Works a contract in February 2016 for the preliminary design of X-59, designed to reduce a sonic boom to a gentle thump.

In 2018, Lockheed Martin Skunk Works was selected for the design, build and flight test of the Low-Boom Flight Demonstrator (LBFD). The X-59 aircraft will collect community response data on the acceptability of the quiet sonic boom generated by our design, helping NASA establish an acceptable commercial supersonic noise standard to overturn current regulations banning supersonic travel over land. This would open the door to an entirely new global market for aircraft manufacturers, enabling passengers to travel anywhere in the world in half the time it takes today.

Israeli Scientists Claim They’re On The Path To A Cure For Cancer

Posted by in category: biotech/medical

Morad said in its infancy, AEBi was essentially “doing what everyone else was doing, trying to discover individual novel peptides for specific cancers.”

But then Morad and his colleague, Dr. Hanan Itzhaki, began attempting to identify why other cancer-killing drugs and treatments didn’t work or eventually failed. And they say they’ve found a way to counter that effect.

Morad said most anti-cancer drugs attack a specific target on or in the cancer cell. “Inhibiting the target usually affects a physiological pathway that promotes cancer. Mutations in the targets – or downstream in their physiological pathways – could make the targets not relevant to the cancer nature of the cell, and hence the drug attacking it is rendered ineffective,” he told The Jerusalem Post.

A Deeper Look At Human Longevity Genes

Posted by in categories: biotech/medical, life extension

(Advances in science and public health are increasing longevity and enhancing the quality of life for people around the world. In this series of interviews with the Milken Institute Center for the Future of Aging, 14 visionaries are revealing exciting trends and insights regarding healthy longevity, sharing their vision for a better future. The Longevity Innovators interviews highlight new discoveries in biomedical and psychosocial science, as well as strategies to promote prevention and wellness for older adults. This is the last story in the series.)

Director of the Longevity Genes Project at the Albert Einstein College of Medicine, Dr. Nir Barzilai has discovered several longevity genes in humans that appear to protect centenarians against major age-related diseases. Barzilai is also co-founder of CohBar, a biotech company developing mitochondria-based therapeutics to treat diseases associated with aging. In an interview with the Milken Institute Center for the Future of Aging, Barzilai explains why some people have longevity genes and the challenges in drug design for age-related diseases:
