This Strange Species That Lives Off Nuclear Energy Is Like Alien Life on Earth

Posted by in categories: alien life, nuclear energy

When you’re trying to figure out what alien life might look like, it makes sense to be looking in the most extreme environments Earth has available.

One such place where life has been found to thrive is three kilometres (1.86 miles) beneath the ground, the home of one of the strangest lifeforms we know: the bacterium Desulforudis audaxviator.

It lives in complete dark, in groundwater up to 60 degrees Celsius (140 Fahrenheit) — an environment devoid of sunlight, oxygen or organic compounds.

Experiment picks up light from the first stars – and it may change our understanding of dark matter

Posted by in category: cosmology

We know this dip should be found in the radiowave part of the electromagnetic spectrum, at a wavelength of 21cm.

Challenging measurement

This was all predicted by theory. But in practice, the signal is extremely challenging to find. This is because it overlaps with many other signals in this region of the spectrum which are much stronger – such as common frequencies on the FM radio dial and radio waves from other events in our galaxy. The reason the team eventually succeeded was partly down to the experiment’s sensitive receiver and small antenna, which lets you cover a large area of the sky more easily.

Revolutionary Eye-drops Developed

Posted by in categories: biotech/medical, nanotechnology

Eye-drops that can repair the corneas and can improve the short and long sightedness have been developed by a team of Ophthalmologists at Shaare Zedek Medical Center and Bar-Ilan University’s Institute of Nanotechnology and Advanced Materials. The solution of nanoparticles called the ‘nanodrops’ was successfully tested on a pig’s cornea. Clinical trials are expected to be carried out later this year. If the clinical trials on humans are successful, it is expected that the need of eyeglasses will be eliminated.

The leader of the research team, Dr. David Smadja, said that the eye-drops can bring a revolution in ophthalmological and optometry treatment of patients who are suffering from myopia, hyperopia and other refractory conditions. The revolutionary breakthrough in the field was revealed by Dr. Smadja at Shaare Zedek’s second biennial research day, which was held at Steinberg Auditorium in Jerusalem. He said that the nano drops can also be used to replace multifocal lenses and allow people to see objects from different distances. Smadja said, “This is a new concept for correcting refractory problems.” However, he didn’t mention the times of applications which will replace the need for the glasses completely.

Medics may slow biological time to save soldiers’ lives

Posted by in categories: biotech/medical, military

Battlefield medics frequently only have a brief window of opportunity to treat an injury before it’s fatal or causes permanent disabilities, and it’s frequently so fleeting that there’s not much they can do. DARPA is exploring an unusual solution to that problem: slow the biological processes to give medics more room to breathe. Its new Biostasis research program aims to bring cell activity to a near halt by using biochemicals that control energetics at the protein level. If animals like tardigrades and wood frogs can stabilize their cells to survive freezing and dehydration, similar techniques might offer more time to medics who want to treat wounds before a victim’s vital systems break down.

DARPA knows this won’t be easy. The trick is to slow down every cellular process at roughly the same rate — you can’t just pause a few while others run at full speed. You’d also have to minimize any damage when the cells return to their normal function.

The Biostasis program is still very young (its first day for answering proposers’ questions is March 20th), and DARPA isn’t expecting too much even from complete projects: it’s initially focusing on “benchtop” proofs of concept and will focus on real-world uses as the program nears its 5-year end. If it has any success, though, the program could prove to be a breakthrough for the medical field as a whole, not just in combat. Paramedics could buy themselves enough time to get a patient to hospital, and doctors could focus less on basic survival and more on full recoveries.

We Can Now Store Light as Sound, And It’s a Game Changer For Computing

Posted by in categories: climatology, computing

Last year, scientists took a big step towards creating the next generation of computers.

For the first time ever, they stored light-based information as sound waves on a computer chip — something the researchers compared to capturing lightning as thunder.

Modified, 3D-printable alloy shows promise for flexible electronics, soft robots

Posted by in categories: 3D printing, engineering, nanotechnology, robotics/AI

Researchers in Oregon State University’s College of Engineering have taken a key step toward the rapid manufacture of flexible computer screens and other stretchable electronic devices, including soft robots.

The advance by a team within the college’s Collaborative Robotics and Intelligent Systems Institute paves the way toward the 3D printing of tall, complicated structures with a highly conductive gallium alloy.

Researchers put nickel nanoparticles into the , galinstan, to thicken it into a paste with a consistency suitable for .

Researchers find algorithm for large-scale brain simulations

Posted by in categories: biotech/medical, information science, neuroscience, supercomputing

An international group of researchers has made a decisive step towards creating the technology to achieve simulations of brain-scale networks on future supercomputers of the exascale class. The breakthrough, published in Frontiers in Neuroinformatics, allows larger parts of the human brain to be represented, using the same amount of computer memory. Simultaneously, the new algorithm significantly speeds up brain simulations on existing supercomputers.

The human brain is an organ of incredible complexity, composed of 100 billion interconnected nerve cells. However, even with the help of the most powerful supercomputers available, it is currently impossible to simulate the exchange of neuronal signals in networks of this size.

“Since 2014, our software can simulate about one percent of the in the human brain with all their connections,” says Markus Diesmann, Director at the Jülich Institute of Neuroscience and Medicine (INM-6). In order to achieve this impressive feat, the software requires the entire main memory of petascale supercomputers, such as the K computer in Kobe and JUQUEEN in Jülich.

Waking up From the Dream of Longevity

Posted by in categories: biological, genetics, internet, life extension, robotics/AI, space

In the course of the last century, science fiction has been a harbinger of things to come. From the automatic sliding doors of Star Trek to visual communication, cyberspace, and even the moon landing, many of our present technological achievements were dreamed up in the futuristic visions of science fiction authors of the 1960s and 70s. Indeed, the fantastical world of science fiction, while not intended to be prophetic, has ended up acting as a blueprint for our modern world.

We have learned from science fiction not only the possibilities of technology, however, but also its irreconcilable dangers. Readers of the genre will recognize the many stories warning us of the hazards of space travel, mind enhancement, and artificial intelligence. These fictional accounts cautioned that if we were not careful, our freedom to transform the world around us would transmogrify into a self-enforced slavery.

Nonetheless, while many of us remembered that these were just stories, intended as speculations about a possible future—in other words, they were fiction before science—through them, we became used to the idea that any advanced technology was inherently dangerous and its use always suspect. Moreover, it became a commonplace idea that technologies whose aim was to change or transform the human being—whether genetic, biological or reconstructive—would lead to a future worthy of Mary Shelley’s Frankenstein.
