Quantum radar to render stealth technologies ineffective

Posted by in categories: computing, military, quantum physics

Stealth technology may not be very stealthy in the future thanks to a US$2.7-million project by the Canadian Department of National Defence to develop a new quantum radar system. The project, led by Jonathan Baugh at the University of Waterloo’s Institute for Quantum Computing (IQC), uses the phenomenon of quantum entanglement to eliminate heavy background noise, thereby defeating stealth anti-radar technologies to detect incoming aircraft and missiles with much greater accuracy.

Ever since the development of modern camouflage during the First World War, the military forces of major powers have been in a continual arms race between more advanced sensors and more effective stealth technologies. Using composite materials, novel geometries that limit microwave reflections, and special radar-absorbing paints, modern stealth aircraft have been able to reduce their radar profiles to that of a small bird – if they can be seen at all.

Many low-lying atoll islands could be uninhabitable

Posted by in categories: climatology, habitats, sustainability

Sea-level rise and wave-driven flooding will negatively impact freshwater resources on many low-lying atoll islands in such a way that many could be uninhabitable in just a few decades. According to a new study published in Science Advances, scientists found that such flooding not only will impact terrestrial infrastructure and habitats, but, more importantly, it will also make the limited freshwater resources non-potable and, therefore, directly threaten the sustainability of human populations.

Most of the world’s atolls are in the Pacific and Indian oceans. The scientists focused on Roi-Namur Island on Kwajalein Atoll in the Republic of the Marshall Islands for their site study from November 2013 to May 2015. The Republic of the Marshall Islands has more than 1,100 low-lying on 29 atolls, is home for numerous island nations and hundreds of thousands of people.

Scientists from the U.S. Geological Survey, Deltares, National Oceanic and Atmospheric Administration, and the University of Hawai?i at Mānoa used a variety of climate-change scenarios to project the impact of sea-level rise and wave-driven flooding on atoll infrastructure and freshwater availability. The approach and findings in this study can serve as a proxy for atolls around the world, most of which have a similar morphology and structure, including, on average, even lower land elevations.

Noninvasive spinal stimulation method enables paralyzed people to regain use of hands, study finds

Posted by in category: biotech/medical

The ability to perform simple daily tasks can make a big difference in people’s lives, especially for those with spinal cord injuries. A UCLA-led team of scientists reports that six people with severe spinal cord injuries—three of them completely paralyzed—have regained use of their hands and fingers for the first time in years after undergoing a nonsurgical, noninvasive spinal stimulation procedure the researchers developed.

At the beginning of the study, three of the participants could not move their fingers at all, and none could turn a doorknob with one hand or twist a cap off a plastic water bottle. Each of them also had great difficulty using a cellphone. After only eight researcher-led training sessions with the spinal stimulation, all six individuals showed substantial improvements. The study participants had chronic and severe paralysis for more than one year, and some for more than 10 years.

From before the first session to the end of the last session, the participants improved their .

Balancing nuclear and renewable energy

Posted by in categories: economics, nuclear energy, solar power, sustainability

Nuclear power plants typically run either at full capacity or not at all. Yet the plants have the technical ability to adjust to the changing demand for power and thus better accommodate sources of renewable energy such as wind or solar power.

Researchers from the U.S. Department of Energy’s (DOE) Argonne National Laboratory and the Massachusetts Institute of Technology recently explored the benefits of doing just that. If nuclear generated in a more flexible manner, the researchers say, the plants could lower electricity costs for consumers, enable the use of more , improve the economics of nuclear and help reduce greenhouse gas emissions.

The team explored technical constraints on flexible operations at and introduced a new way to model how those challenges affect how power systems operate. “Flexible nuclear power operations are a ‘win-win-win,’ lowering power system operating costs, increasing revenues for nuclear plant owners and significantly reducing curtailment of renewable energy,” wrote the team in an Applied Energy article published online on April 24.

Some People Worry if Rejuvenation is Available they May be Forced to Use it

Posted by in categories: biotech/medical, life extension

Hard to believe but some people are worried that when rejuvenation biotechnology is available they may be forced to use it.

Might rejuvenation become an imposition?

Suppose that, on a nice day not too far into the future, while everything is going reasonably well in your life and you are enjoying yourself, you walk into the doctor’s office for a regular checkup. The doctor finds nothing wrong with you, but in order to minimize your risk of developing diseases that are likely to strike people in your age range, she recommends that you undergo senolytic treatment. The treatment is safe, with no serious adverse effects, it is administered simply through injections, and it is either state-subsidized or otherwise affordable. In your opinion, what are the odds that you would refuse the doctor’s prescription and say that you’d rather take the risk of getting sick?

Jeff Bezos v the world: why all companies fear ‘death

Posted by in categories: business, robotics/AI

Rain Design isn’t the first company to fall victim to the aggressive techniques Amazon uses to achieve market dominance. Although its retail site is the most visible of its business strands, the $740bn company has quietly stretched its tentacles into an astonishing range of unrelated industries. Google and Facebook might have cornered the online advertising market, but Amazon’s business successes now include groceries, TV, robotics, cloud services and consumer electronics.
