What happens when you CRISPR people?

Few questions generated more contentious discussion in biotech in the mid-2010s, as researchers and executives debated the relative merits of preclinical studies that pointed both to the new gene-editing tool’s potential to cure numerous diseases and its potential to cause unintended genetic damage.

The European research consortium EUROfusion has announced the start of a five-year conceptual design phase for its demonstration fusion power plant DEMO, capable of net electricity production, shortly after the middle of the century in its Roadmap to Fusion Energy.

The first-of-its-kind facility represents the next technological step after the global ITER fusion experiment. It aims to demonstrate the net production of 300 to 500 megawatt of electricity generated by nuclear fusion, clean and safe energy, as well as essential technologies such as remote maintenance and tritium breeding. The tritium breeding technology will allow operators to produce the tritium fusion fuel on-site is a crucial requirement not just for DEMO but also for any future fusion power device to follow ITER.

Fusion is the process that powers stars like our Sun and promises an inherently safe and nearly unlimited long-term clean energy source here on Earth. Fusion energy will generate immense amounts of energy from just a few grams of the abundant fuels found all over the world.

Selmer Bringsjord, and his colleagues have proposed the Lovelace test as a substitute for the flawed Turing test. The test is named after Ada Lovelace.

Bringsjord defined software creativity as passing the Lovelace test if the program does something that cannot be explained by the programmer or an expert in computer code.2 Computer programs can generate unexpected and surprising results.3 Results from computer programs are often unanticipated. But the question is, does the computer create a result that the programmer, looking back, cannot explain?

When it comes to assessing creativity (and therefore consciousness and humanness), the Lovelace test is a much better test than the Turing test. If AI truly produces something surprising which cannot be explained by the programmers, then the Lovelace test will have been passed and we might in fact be looking at creativity. So far, however, no AI has passed the Lovelace test.4 There have been many cases where a machine looked as if it were creative, but on closer inspection, the appearance of creative content fades.

Physicists have discovered that certain magnetic material freezes when the temperature rises to a certain point. We’ve typically only seen this behavior when we cool down magnetic materials, not when we heat them up. As such, it has left physicists scratching their heads and baffled by the development.

Physicists Alexander Khajetoorians of Radboud University in the Netherlands says that the freezing of the magnetic materials is the opposite of what we normally see. The result is “counterintuitive, like water that becomes an ice cube when it’s heated up,” according to Khajetoorians.

Normally, ferromagnetic materials like iron feature aligned spins. This means that the magnetic spins of the atoms are all spinning in the same direction. Essentially, the south and north magnetic poles are all aligned in the same direction. Some alloys made of both iron and copper, though, feature randomized spins. Physicists refer to this state as spin glass.

Though they are discrete particles, water molecules flow collectively as liquids, producing streams, waves, whirlpools, and other classic fluid phenomena.

Not so with electricity. While an electric current is also a construct of distinct particles—in this case, —the particles are so small that any among them is drowned out by larger influences as electrons pass through ordinary metals. But, in certain materials and under specific conditions, such effects fade away, and electrons can directly influence each other. In these instances, electrons can flow collectively like a fluid.

Now, physicists at MIT and the Weizmann Institute of Science have observed electrons flowing in vortices, or whirlpools—a hallmark of fluid flow that theorists predicted electrons should exhibit, but that has never been seen until now.

NLM’s NCBI is introducing the Comparative Genome Viewer (CGV), an easy-to-use visualization tool that helps you quickly compare eukaryotic genome assemblies and easily identify genomic changes that may be significant to biology and evolution. With the new CGV you can view and compare the alignment between two assemblies to see differences in genomic sequence and structure, including deletions, inversions, and translocations. Currently, you can compare assemblies from over 50 annotated animal and plant genomes.

A team of physicists at the University of Edinburgh’s School of Physics and Astronomy has used mathematical calculations to show that quantum communications across interstellar space should be possible. In their paper published in the journal Physical Review D, the group describes their calculations and also the possibility of extraterrestrial beings attempting to communicate with us using such signaling.

Over the past several years, scientists have been investigating the possibility of using quantum communications as a highly secure form of message transmission. Prior research has shown that it would be nearly impossible to intercept such messages without detection. In this new effort, the researchers wondered if similar types of communications might be possible across . To find out, they used that describes that movement of X-rays across a medium, such as those that travel between the stars. More specifically, they looked to see if their calculations could show the degree of decoherence that might occur during such a journey.

With quantum communications, engineers are faced with quantum particles that lose some or all of their unique characteristics as they interact with obstructions in their path—they have been found to be quite delicate, in fact. Such events are known as decoherence, and engineers working to build quantum networks have been devising ways to overcome the problem. Prior research has shown that the space between the stars is pretty clean. But is it clean enough for ? The math shows that it is. Space is so clean, in fact, that X-ray photons could travel hundreds of thousands of light years without becoming subject to decoherence—and that includes gravitational interference from astrophysical bodies. They noted in their work that optical and microwave bands would work equally well.
