We’re at least a one step closer to creating the “Star Trek”-style Teleportation. The concept of Quantum teleportation, the act of reconstructing quantum data somewhere else, is impressive just by itself. A team of  scientists at the US’ National Institute of Standards and Technology have managed to one-up that feat. They’ve shattered the distance record for quantum teleportation.

Sounds like a real time Sci-Fi

The team successfully  managed to transfer the information from one photon to another across 63 miles of optical fiber. That may not sound like much, but it’s a remarkable achievement as 99 percent of photons would never make the complete trip. It was only possible thanks to newer detectors that could pick up the faint signal of the lone light particle.

Real time teleportation, as seen in sci-fi movies, is still a long way to go, but the achievement does open the door to many possibilities in quantum computing. You could use unbreakable quantum encryption at inter-city distances, for instance. Imagine a future with more instantaneous communication with astronauts in space or rovers on Mars alongside unprecedented network speed and security thanks to quantum encryption.

When it comes to living things that glow, a plant is probably your best choice to have in your home than a jellyfish, or even a glow-in-the-dark cat or pig. Bioglow is preparing to offer its bioengineered houseplants to the public which will glow in the dark.

Bioglow has been leading the movement ever since molecular biologist Alexander Krichevsky created what the company calls the first light-producing plants and published his findings in 2010. But there are still a lot of limitations with these initial batches of glowing plants. They are best viewed in a dark room after giving your eyes time to adjust. The plants also have a short lifespan of only two to three months.

Each Starlight Avatar, as the company calls it, is shipped in a see-through box and grows in a nutrient gel. The plant can be transferred to a pot once it’s outgrown its container, but about half of them don’t survive the transplant. They also need to be kept away from direct sunlight.

According to Bioglow

“Starlight Avatar™ is an indoor plant and is unlikely to survive in an open garden due to strong susceptibility to a variety of abiotic conditions, particularly light and water shock.”

Your first crack at buying a Starlight Avatar of your own will be through an upcoming online auction where you can sign up to participate and bid for one of 20 plants, though the official date of the auction hasn’t yet been announced. Also the plants are only available to ship to the US.

They could conceivably become renewable light sources in the future. It’s within the realm of possibility, but, in the meantime, you’ll have to settle for spending a few months with a glowing plant.

artificial heart

An artificial heart from Carmat has found its way to first human patient in France. The procedure was performed on December 18, 2013 by the Georges Pompidou European Hospital team in Paris (France). “The implantation went smoothly, with the prosthesis automatically providing blood flow at physiologic conditions. The patient is currently being monitored in the intensive care unit. He is awake and talks with his family.” – Carmat

While synthetic hearts aren’t new, what sets the new Carmat “bioprosthetic” model apart is the way it uses existing biological tissue. Two chambers in the heart are divided by a membrane. In one chamber hydraulic fluid is held in place. A pump with in the heart pushes the fluid in and out of the chambers, which causes the blood to flow on the other side.

According to Piet Jansen, chief medical officer of Carmat:

The idea was to develop an artificial heart in which the moving parts that are in contact with blood are made of tissue that is [better suited] for the biological environment.

Carmat first won approval from four different cardiac centers in Saudi Arabia, Slovenia, Poland, and Belgium. The company’s home country of France eventually came on board in September and Health Minister Marisol Touraine is wasting no time in touting Carmat’s success. “This news brings great pride to France,” she told BFM TV. “It shows we are pioneers in healthcare, that we can invent, that we can carry an innovation that will also bring great hope to plenty of people.”

“We are delighted with this first implant, although it is premature to draw conclusions given that a single implant has been performed and that we are in the early postoperative phase,”  Carmat’s CEO Marcelo Conviti said in a statement.

Carmat’s artificial heart weighs three times than that of human heart. It can beat for up to five years and is designed for patients suffering from end-stage heart failure. But it won’t come cheap: the device is expected to cost around 150,000 euros (over $195,000). Carmat has other patients lined up for early human trials. If the tests turn out successful, this new heart could offer some much needed hope to the roughly 5.7 million people in the United States suffering from heart failure at any given time.

SheerWind, a company based in Minnesota, claims to have a new technology for wind power generation that can alleviate most of the world’s concerns. The technology called Invelox system can operate in a wider variety of conditions and is claimed to have an efficiency up to 600% than traditional wind turbines.

Traditional wind turbines you’re used to see rely on fairly swift winds to function. However the Invelox system can generate power from winds as gentle as 1-2 MPH.

“It does this by capturing passing breezes in large scoops at the top of its 40-50 foot tower. The wind is funneled down toward the ground through an increasingly narrow space. When the air is compressed, it speeds up and is used to power a small turbine generator.”

SheerWind is trying to prove that the system is 6 times more efficient than the traditional wind turbines, but it’s currently doing so with internal testing. The company tested its turbine both with and without the Invelox cowling. When it compared the values over time, that works out to energy production improvements anywhere from 81-660%. The average was 314%.

The company says it has been able to produce wind power at a cost of $750 per kilowatt, including installation. This brings it in-line with the final cost of energy from natural gas and hydropower. The energy industry is all about cost effectiveness and efficiency, so if the Invelox technology is legit, it’s going to be huge. Invelox takes up much less space than traditional windmills, and it poses little to no risk to birds or curious children.

Defense Advanced Research Projects Agency (DARPA), the military’s futuristic research agency, is ready to “break the glass ceiling” of space telescopes by aiming for a new design into orbit that’s made of plastic instead of traditional glass and unfolds into a mammoth space telescope.

DARPA’s new program is called Membrane Optical Imager for Real-Time Exploitation (MOIRE). The new orbital telescope will be bigger and lighter than previous imaging satellites, making it easier to spy on larger areas and for longer periods of time.


This giant telescope could view approximately 40 percent of the earth’s surface at once.

It will be a tightly packed cluster of petals having diameter of 20 feet. MOIRE stretches to 68 feet across. After its launch it will be placed 22,000 miles above the earth. From orbit, this giant telescope could view approximately 40 percent of the earth’s surface at once. It will be able to record high resolution images and video, making it the ultimate spying satellite. However it could also be beneficial in weather forecasting and disaster response.

High resolution imagery was not possible with the traditional large diameter mirrors because of its thickness and weight. Also it was quite expensive to implement such technology in Space Telescopes. According to DARPA – “The glass mirrors are rapidly approaching the point where they will be too large, heavy and costly for even the largest of today’s rockets.”

“Membrane optics could enable us to fit much larger, higher-resolution telescopes in smaller and lighter packages,” said Lt. Col. Larry Gunn, Darpa program manager, in a statement. “In that respect, we’re ‘breaking the glass ceiling’ that traditional materials impose on optics design.”

Instead of reflecting light with mirrors or refracting it with lenses as traditional space telescopes do, MOIRE’s membrane uses concept of optics diffraction. And because MOIRE is so much lighter and smaller at launch, budget wise it will be much more efficient.

“We’re hoping our research could also help greatly reduce overall costs and enable more timely deployment using smaller, less expensive launch vehicles,” said Gunn.

According to DARPA, the MOIRE program is in its second and final phase and recently demonstrated a ground-based prototype.

lemon shark

Like Salmon and Sea turtles, the female lemon sharks return to their birthplace to give birth, an almost 20-year Research conducted in Bimini in The Bahamas reports.

The ongoing project since 1995 that involved capturing, tagging, releasing and tracking of more than 2K baby lemon sharks brought in a noteworthy phenomenon of sharks returning to their native birth place when it’s their time of giving birth, U.S. researchers reported.

We found that newborn sharks captured in the mid-1990s left the safety of the islands when they were between 5 and 8 years old,” researcher Kevin Feldheim of Chicago’s Field Museum said.

Despite their impressive travels, female lemon sharks always return to the same location where they were born to give birth

Yet, despite leaving and visiting many other islands in their travels, these sharks ‘remember’ where they were born after a decade of roving, and are able to find the island again when they are pregnant and ready to give birth,” he said.

Such a long surmising project was supported by student volunteers, who came to Bahamas, effort to prove the speculation was true.

Spanning the behavior of lemon sharks for almost two decades have resulted in the confirmation of the female sharks’ ability to return back to their birthplace to give birth but the difficulty of keeping track of sharks from birth to maturity has made confirmation of the behavior a struggle, the researchers said.

Evidence that sharks utilize the same nursery areas across generations underscores the critical importance of preserving local nursery habitats and can provide strong input in designating inshore marine reserves that would protect sharks of future generations, the researchers said.

fresh water under seabed

“Vast freshwater reserves are trapped beneath the ocean floor which could sustain future generations as current sources dwindle”, say an international team of scientists.

Scientists estimate that around 500,000 cubic kilometres of low-salinity water is trapped under the seabed on continental shelves around the world, including Australia, China, North America and South Africa. According to an Australian lead author, Vincent Post, a groundwater hydrogeologist from Flinders University in Adelaide.

“The volume of this water resource is a hundred times greater than the amount we’ve extracted from the Earth’s sub-surface in the past century since 1900,”

According to Post The Freshwater on our planet is increasingly under stress and strain so the discovery of significant new stores off the coast is very exciting. “It means that more options can be considered to help reduce the impact of droughts and continental water shortages.” says Post

The water use on our planet has been growing at more than twice the rate of population in the last century due to demands such as irrigated agriculture and meat production as per UN Waters predictions. Almost half of the world’s population is living in conditions of water scarcity. By 2030, 47 % of people are expected to face water shortage. Prior to these findings such undersea water reserves were considered to be rare.

“By combining all this information we’ve demonstrated that the freshwater below the seafloor is a common finding, and not some anomaly that only occurs under very special circumstances,” he says.

These deposits were expected to be formed over hundreds of thousands of years in the past, when the sea level was much lower and oceans surface was exposed to rainfall which was absorbed into the underlying water table. The coastlines disappeared when the polar icecaps started melting about 20,000 years ago. But these water reserves remained mostly intact thanks to clay and sediment layers.

“In some case you have actually have fresh water under the sea, but in most cases it’s a mixture between freshwater and sea water – we call that brackish water. For some areas it is economically viable to desalinate that brackish water and make it economically competitive with other sources of water recovery.” says Post.

Great care would have to be taken not to contaminate these water reserves.

According to Post drilling for this water would be expensive and great care would have to be taken not to contaminate these water reserves as these are precious resources. “We should use them carefully: once gone, they won’t be replenished until the sea level drops again, which is not likely to happen for a very long time,” says Post. Humans don’t have a good track record when it comes to exploiting the world’s groundwater resources, such as the Great Artesian Basin.

“We just squandered the water,” says Davis, who was previously with CSIRO, the World Bank and the National Water Commission.

“In the Great Artesian Basin case we spent around 100 years pumping the water to the surface and letting it flow free and evaporate, using only a very very small fraction of what we tapped,” he says. As a result, says Davis, Australia has had to undertake a very expensive remedial program to try and cap the free-flowing bores to save water. He says there are similar stories in Africa and China.

“What concerns me here is that we don’t take the same approach again,” says Davis.

Let’s be slow, cautious and thoughtful about it this time and show how we can act responsibly.

The ocean is still a vastly unexplored world that is full of mysteries, and with the growing technology, we frequently discover more oddities and fascinating creatures from its depths. Such research attempts are soon going to have a massive boon in the form of an ocean-based research laboratory called the SeaOrbiter. The station will have laboratories, workshops, living quarters and a pressurized deck to support divers and submarines.

“SeaOrbiter is the only vessel in the world allowing a 24/7 exploration on long-term missions of the open sea and the abyss.”

The SeaOrbiter, which seems to be an amazing spaceship like structure, is the work of Jacques Rougerie, a sea architect, and various experts, among them being the former NASA head Daniel Goldin.  The cost is expected to be around $52.7 million. On completion the project will result in a vessel that is basically the ISS of the ocean, able to hold up to 22 researchers and crew members initially.

The laboratory is semi-submersible vessel and weighs 1000 tons. It has a total height of 51 meters with 31 meters below sea level., and will harvest renewable energy from wind, sun, and waves. It is designed to float vertically and drift with the ocean currents but has two small propellers allowing it to modify its trajectory and maneuver in confined waters. Underwater robots can be sent from the laboratory to explore the seabed. The hull is made of an alloy comprising aluminum and magnesium is five times thicker than that of a conventional vessel.

Its vertical alignment in the sea will leave a small part visible above the surface with much larger accommodation and laboratories below the sea’s surface. Some levels will have a cabin pressure equal to the external water pressure allowing divers to live for extended periods at depth and make frequent excursions.

Rougerie said in a message to the folks at Fast Company: “The SeaOrbiter is the synthesis of everything that we have been able to do at sea: it is at the same time a moving habitat and a dynamic launching point for submarine research and exploration. It will not replace oceanographic boats or exploratory submarines. Instead, it’s another way to explore and better comprehend the underwater universe and bring human life at sea to another level on a 24/7 basis and over long periods.”

Life after death

Is there an afterlife?

Many scientists would dismiss the concept for lack of proof but one expert claims he has evidence to confirm once and for all that there is indeed a life after death. According to Professor Robert Lanza the answer lies in theory of Biocentrism.

Biocentrism — also known as the biocentric universe — is a theory proposed in 2007 by American scientist Robert Lanza. According to this theory — life creates the universe rather than the other way around. Biocentrism asserts that current theories of the physical world do not work, and can never be made to work, until they fully account for life and consciousness.

Lanza’s biocentric theory builds on quantum physics. While physics is considered fundamental to the study of the universe, and chemistry fundamental to the study of life, biocentrism places biology before the other sciences to produce a theory of everything.

Professor Robert Lanza says the evidence lies in the idea that the concept of death is a mere figment of our consciousness. “We think life is just the activity of carbon and an admixture of molecules – we live a while and then rot into the ground”, said the scientist on his website.

Biocentrism explains that the universe only exists because of an individual’s consciousness of it. Life and biology creates the universe; the universe itself does not create life. The same applies to the concepts of space and time, which Professor describes as “simply tools of the mind”.

According to professor the concept of death as we know it is “cannot exist in any real sense” as there are no true boundaries by which to define it. The idea of dying is essentially something we have long been taught to accept, but in reality it just exists in our minds. Professor says that once we begin to question our preconceived concepts of time and consciousness, the alternatives are huge and could alter the way we think about the world in a way not seen since the 15th century’s “flat earth” debate.

Professor Lanza says it can be explained far more simply using colours. Essentially, the sky may be perceived as blue, but if the cells in our brain were changed to make the sky look green, was the sky truly blue or was that just our perception?

When we die, we do so not in the random billiard-ball-matrix but in the inescapable-life-matrix.

Professor Lanza explains that, when we die, our life becomes a “perennial flower that returns to bloom in the multiverse”. He added: “Life is an adventure that transcends our ordinary linear way of thinking. When we die, we do so not in the random billiard-ball-matrix but in the inescapable-life-matrix.”

A scientist exploring the effects of alcohol on the brain said a cure for Hangover is closer than you think. He’s busy devising a substitute beverage that can eliminate the toxic health effect of alcohol on the liver, heart and brain.

Writing in The Guardian, David Nutt — a professor at Imperial College in London — said he had identified compounds that are effective substitutes to alcohol, that mimic the effects of booze on the brain.

To test them out he had a few drinks.

‘Within minutes of taking the antidote I was up giving a lecture with no impairment whatsoever.’ – David Nutt

“In theory we can make an alcohol surrogate that makes people feel relaxed and sociable and remove the unwanted effects, such as aggression and addictiveness,” –  David Nutt.

At present Professor Nutt is seeking funding for testing and marketing the product. But one thing for sure he will have no challenge finding test subjects.
