Bacteria may not have a central or sensory nervous system as we know it, but they can still physically “feel” the world around them, according to a new study.

It turns out the tiny microorganisms don’t just respond to chemical signals — they also have a sense of touch, and can recognise surfaces and respond to them. Wow.

Our sense of touch is a very important tool for living in the world. It helps avoid hazards and dangerous surfaces, and keeps you from crushing delicate objects.

Quantum physicists in Oriol Romero-Isart’s research group in Innsbruck show in two current publications that, despite Earnshaw’s theorem, nanomagnets can be stably levitated in an external static magnetic field owing to quantum mechanical principles. The quantum angular momentum of electrons, which also causes magnetism, is accountable for this mechanism.

Already in 1842, British mathematician Samuel Earnshaw proved that there is no stable configuration of levitating permanent magnets. If one magnet is levitated above another, the smallest disturbance will cause the system to crash. The magnetic top, a popular toy, circumvents the Earnshaw theorem: When it is disturbed, the gyrating motion of the top causes a system correction and stability is maintained. In collaboration with researchers from the Max Planck Institute for Quantum Optics, Munich, physicists in Oriol Romero-Isart’s research group at the Institute for Theoretical Physics, Innsbruck University, and the Institute for Quantum Optics and Quantum Information, Austrian Academy of Sciences, have now shown that: In the quantum world, tiny non-gyrating nanoparticles can stably levitate in a magnetic field.

Over just a few short years the CRISPR gene-editing technique has revolutionized science, affecting everything from medicine to agriculture. Two new breakthrough studies have just been published describing dual methods that make the process more precise and efficient paving the way for scientists to safely alter DNA mutations that cause thousands of different human diseases.

CRISPR is conventionally a cut-and-paste tool allowing scientists to chop out unwanted strands of DNA and insert new genes, but a large volume of human diseases are caused by a single point mutation somewhere in a person’s DNA. Up until now scientists have not been able to simply and directly erase or rewrite these single mutations in living human cells.

Our human genome consists of 3 billion base pairs made up of chemical units referred to by the letters A, C, G and There are 50,000 known genetic mutations that are linked to disease in humans and 32,000 of these are single point mutations. Half of those single point mutations have been identified as a G-C pair that has mutated into an A-T pair.

Ray Kurzweil is director of engineering at Google but he is better known for writing best-selling books outlining the future of artificial intelligence.

He has made 147 predictions on the future of technology including the ubiquity of wearable devices and the move from desktops and laptops to smartphones and tablets. In fact, his prediction rate has been rated 86 per cent accurate.

With this in mind, fans were excited to see Kurzweil answer their questions in a live streaming interview session last week where he elaborated on his predictions.

Humanity has sought to make the Earth’s oceans potable for thousands of years. The Norse tale of Utgarda-Loki tells of Odin being tricked into drinking from a horn connected to the sea, while Exodus 15:22–26 of the Bible likely describes Moses desalinating the water of Marah:

When they came to Marah, they could not drink the water of Marah because it was bitter; therefore it was named Marah. And the people grumbled against Moses, saying, “What shall we drink?” And he cried to the Lord, and the Lord showed him a log, and he threw it into the water, and the water became sweet.

Even the Greek philosopher Aristotle once observed that “salt water, when it turns into vapor, becomes sweet and the vapor does not form salt water again when it condenses.” Yet, despite the continued accelerating pace of technological advancement since we switched from BC to AD, turning salt water into fresh has remained more expensive than transforming it into wine. But as climate change continues to ravage the world’s watersheds, we may soon have little choice other than to turn to the sea’s bounty of H2O to keep our growing global population from getting parched.
