NASA proposes a magnetic shield to protect Mars’ atmosphere

Posted by in category: space travel

This week, NASA’s Planetary Science Division (PSD) hosted a community workshop at their headquarters in Washington, DC. Known as the “Planetary Science Vision 2050 Workshop”, this event ran from February 27th to March 1st, and saw scientists and researchers from all over the world descend on the capitol to attend panel discussions, presentations, and talks about the future of space exploration.

One of the more intriguing presentations took place on Wednesday, March 1st, where the exploration of Mars by human astronauts was discussed. In the course of the talk, which was titled “A Future Mars Environment for Science and Exploration”, Director Jim Green discussed how deploying a could enhance Mars’ atmosphere and facilitate crewed missions there in the future.

The current scientific consensus is that, like Earth, Mars once had a magnetic field that protected its atmosphere. Roughly 4.2 billion years ago, this planet’s magnetic field suddenly disappeared, which caused Mars’ atmosphere to slowly be lost to space. Over the course of the next 500 million years, Mars went from being a warmer, wetter environment to the cold, uninhabitable place we know today.

Team reprograms CRISPR system in mice to eliminate tumor cells without affecting healthy cells

Posted by in categories: biotech/medical, genetics, neuroscience

The CRISPR/Cas9 gene-editing tool is one of the most promising approaches to advancing treatments of genetic diseases—including cancer—an area of research where progress is constantly being made. Now, the Molecular Cytogenetics Unit led by Sandra Rodríguez-Perales at the Spanish National Cancer Research Centre (CNIO) has taken a step forward by effectively applying this technology to eliminate so-called fusion genes, which in the future could open the door to the development of cancer therapies that specifically destroy tumors without affecting healthy cells. The paper is published in Nature Communications.

Fusion genes are the abnormal result of an incorrect joining of DNA fragments that come from two different genes, an event that occurs by accident during the process of cell division. If the cell cannot benefit from this error, it will die and the will be eliminated. But when the error results in a reproductive or survival advantage, the carrier cell will multiply and the genes and the proteins they encode thus become an event triggering tumor formation. “Many and the fusion genes they produce are at the origin of childhood sarcomas and leukaemias,” explains Sandra Rodríguez-Perales, lead co-author of the study now published by the CNIO. Fusion genes are also found in among others prostate, breast, lung and brain tumors: in total, in up to 20% of all cancers.

Because they are only present in tumor cells, fusion genes attract a great deal of interest among the scientific community because they are highly specific therapeutic targets, and attacking them only affects the tumor and has no effect on .

The Coming Internet: Secure, Decentralized and Immersive

Posted by in categories: computing, disruptive technology, electronics, information science, internet, open access, supercomputing

The blockchain revolution, online gaming and virtual reality are powerful new technologies that promise to change our online experience. After summarizing advances in these hot technologies, we use the collective intelligence of our TechCast Experts to forecast the coming Internet that is likely to emerge from their application.

Here’s what learned:

Security May Arrive About 2027 We found a sharp division of opinion, with roughly half of our experts thinking there is little or no chance that the Internet would become secure — and the other half thinks there is about a 60% probability that blockchain and quantum cryptography will solve the problem at about 2027. After noting the success of Gilder’s previous forecasts, we tend to accept those who agree with Gilder.

Decentralization Likely About 2028–2030 We find some consensus around a 60% Probability and Most Likely Year About 2028–2030. The critical technologies are thought to focus on blockchain, but quantum, AI, biometrics and the Internet of things (IoT) also thought to offer localizing capabilities.

US Air Force aims to train pilots faster using brain electrode

Posted by in categories: military, neuroscience

In August, the US Air Force Research Laboratory 711th Human Performance Wing launched its iNeuraLS project, an effort to speed up pilot training through brain stimulation.

Some will feel a slight tingling sensation. Others will feel nothing at all.

The electrode placed inside the ear canal isn’t designed to shock. Rather, the US Air Force Research Laboratory (ARFL) believes the earbud-like device, when placed next to the brain’s vagas nerve, will have more of an intellectually stimulating effect. It ought to create moments of super learning, controllable periods of focus that allow pilots to soak up their flight training faster than humanly possible.

At Project Convergence, the US Army experienced success and failure — and it’s happy about both

Posted by in category: military

“I was focused on those 10 people up front that were simulating a tactical operation and a little less so on the screens,” McCarthy told reporters the day after the exercise. “The only screens that I really cared about were the lower ones that showed how they were moving the pieces from the battlefield.”

In other words, Project Convergence was not about the boom. It was not about hitting the targets.

Which is good. Because not all of them did.
