One of the more well-known rules in physics is that light can only ever go one speed, so long as nothing stands in its way.
But new research has found there could be an interesting exception to this rule, where the mixing of light waves could bring them to a complete standstill.
The discovery hints at new ways of wrangling not just photons but nearly any kind of wave, which could be useful in technology that relies on information sent and stored using light.
Will the benefits of making data more widely available outweigh such risks? The signs are that they will. Plenty of countries are now opening up their medical records, but few have gone as far as Sweden. It aims to give all its citizens electronic access to their medical records by 2020; over a third of Swedes have already set up accounts. Studies show that patients with such access have a better understanding of their illnesses, and that their treatment is more successful. Trials in America and Canada have produced not just happier patients but lower costs, as clinicians fielded fewer inquiries. That should be no surprise.

NO WONDER they are called “patients”. When people enter the health-care systems of rich countries today, they know what they will get: prodding doctors, endless tests, baffling jargon, rising costs and, above all, long waits. Some stoicism will always be needed, because health care is complex and diligence matters. But frustration is boiling over. This week three of the biggest names in American business—Amazon, Berkshire Hathaway and JPMorgan Chase—announced a new venture to provide better, cheaper health care for their employees. A fundamental problem with today’s system is that patients lack knowledge and control. Access to data can bestow both.
The internet already enables patients to seek online consultations when and where it suits them. You can take over-the-counter tests to analyse your blood, sequence your genome and check on the bacteria in your gut. Yet radical change demands a shift in emphasis, from providers to patients and from doctors to data. That shift is happening. Technologies such as the smartphone allow people to monitor their own health. The possibilities multiply when you add the crucial missing ingredients—access to your own medical records and the ability easily to share information with those you trust. That allows you to reduce inefficiencies in your own treatment and also to provide data to help train medical algorithms. You can enhance your own care and everyone else’s, too.

Two women with gene mutation that causes degenerative disorder will undergo therapy.

Scientists thought the Milky Way and Andromeda galaxies were unique: They’ve got rings of smaller dwarf galaxies orbiting in what seems to be a synchronized fashion. But when a team of scientists recently looked at another galaxy, they realized it also seemed to shepherd a flock of dwarfs in a strange, synchronized dance. That’s not supposed to happen.
An international team of four researchers noticed the behavior in the elliptical Centaurus A galaxy, 30 million light years away from our own Milky Way. Dwarf galaxies should travel randomly around their parent, based on the standard theory of how galaxies form. Seeing yet another galaxy with this strange behavior is highly unlikely, and calls into question the very model that scientists use to understand structure in our universe.
Sure, you would expect to find one galaxy with this behavior, study author Oliver Müller from the University of Basel in Switzerland told Gizmodo. “But two or three is startling.”
Using a new technique they call “in-air microfluidics,” University of Twente scientists succeed in printing 3D structures with living cells. This special technique enable the fast and ‘on-the-fly’ production of micro building blocks that are viable and can be used for repairing damaged tissue, for example. The work is presented in Science Advances.
Microfluidics is all about manipulating tiny drops of fluid with sizes between a micrometer and a millimeter. Most often, chips with tiny fluidic channels, reactors and other components are used for this: lab-on-a-chip systems. Although these chips offer a broad range of possibilities, in producing emulsions for example—droplets carrying another substance – the speed at which droplets leave the chip is typically in the microliter per minute range. For clinical and industrial applications, this is not fast enough: filling a volume of a cubic centimeter would take about 1000 minutes or 17 hours. The technique that is presented now, does this in a couple of minutes.
Summary: Activating T cells in tumors destroyed most traces of cancer in mice, and had ‘amazing, bodywide effects,’ Stanford University researchers reported. The researchers are recruiting lymphoma patients to test the approach in a clinical trial. [This article first appeared on the website LongevityFacts.com. Author: Brady Hartman. ]
Researchers at the Stanford University School of Medicine used two novel agents to activate immune system T cells in tumors. The immune-boosting treatment destroyed most traces of cancer in mice the researchers reported in a study published on Jan. 31 in the journal Science Translational Medicine.
Injecting tiny amounts of two immune-stimulating agents directly into solid tumors in mice can eradicate all traces of cancer in the rodents, including distant metastases, the researchers found. The novel approach works for many different types of cancers, including tumors that arise spontaneously, the new study found.

We are pleased to announce a special event in San Francisco on Friday, February 2, 2018, 7:00 PM – 11:00 PM PST the opportunity to meet Dr. Aubrey de Grey from the SENS Foundation who will also be attending. This is a special screening of Altered Carbon, a new science fiction series coming to Netflix and based on the superb book by Richard Morgan.
Image: istolethetv/Flickr Perhaps we’re not alone but instead reside in a multiverse stocked with all sorts of fantastical realms. These other universes are somewhat—but not exactly—like our own. Maybe gravity acts differently, or particles come in different shapes and sizes. Could life still exist in any of these bubbles? A team of researchers at the University of Michigan asked these questions but took things a step further. They removed one of the four fundamental forces of nature, the weak nuclear force, from their hypothetical universes. And according to their calculations, these alter…
