Quantum information in quantum cognition

Posted by in categories: neuroscience, particle physics, quantum physics

Some research topics, says conventional wisdom, a physics PhD student shouldn’t touch with an iron-tipped medieval lance: sinkholes in the foundations of quantum theory. Problems so hard, you’d have a snowball’s chance of achieving progress. Problems so obscure, you’d have a snowball’s chance of convincing anyone to care about progress. Whether quantum physics could influence cognition much.

Quantum physics influences cognition insofar as (i) quantum physics prevents atoms from imploding and (ii) implosion inhabits atoms from contributing to cognition. But most physicists believe that useful entanglement can’t survive in brains. Entanglement consists of correlations shareable by quantum systems and stronger than any achievable by classical systems. Useful entanglement dies quickly in hot, wet, random environments.

Brains form such environments. Imagine injecting entangled molecules A and B into someone’s brain. Water, ions, and other particles would bombard the molecules. The higher the temperature, the heavier the bombardment. The bombardiers would entangle with the molecules via electric and magnetic fields. Each molecule can share only so much entanglement. The more A entangled with the environment, the less A could remain entangled with B. A would come to share a tiny amount of entanglement with each of many particles. Such tiny amounts couldn’t accomplish much. So quantum physics seems unlikely to affect cognition significantly.

For The First Time, DNA Has Been Edited With CRISPR in Space

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

Humans may not be able to burp properly in space, but we can now edit a genome. For the first time, astronauts aboard the International Space Station (ISS) have used CRISPR-Cas9 to edit the DNA of brewer’s yeast.

The goal wasn’t to create super space yeast. The astronauts were studying how DNA repair mechanisms work in space, so they snipped through strands of the fungus’s genetic code in a number of places to mimic radiation damage.

“The damage actually happens on the space station and the analysis also happens in space,” said Emily Gleason of miniPCR Bio, the company that designed the DNA lab aboard the ISS. “We want to understand if DNA repair methods are different in space than on Earth.”

CERN travelling science exhibit comes to India: Here’s when and where you can catch it

Posted by in categories: energy, science

The science exhibition, which goes by the name “Vigyan Samagam”, will highlight India’s contributions to some of the world’s biggest science projects. It is a jointly-funded effort by the Department of Atomic Energy (DAE) and the Department of Science & Technology (DST).

While in India, the CERN exhibit will be bilingual — in English and Hindi for the public to make the most of.

A Volcano in Bali Along The ‘Ring of Fire’ Erupted on Saturday, And It Looks Terrifying

Posted by in category: futurism

A volcano erupted on the Indonesian island of Bali Saturday, sending ash into the sky over surrounding villages and lava pouring down its sides.

The island’s Mount Agung put national agencies on notice, causing some flight cancellations but no reported casualties with the eruption, which reportedly spread lava and incandescent rocks over about two miles.

The national disaster agency said Mount Agung’s eruption lasted four minutes and 30 seconds, according to multiple reports.

Scientists Discover Unexpected Underwater Volcano off the Coast of Africa

Posted by in category: neuroscience

Geologists first noticed something unusual in the Indian Ocean in November last year, when they detected a massive seismic event originating from a spot near to the French island of Mayotte. Now further research has revealed that the source of the seismic activity is an enormous underwater volcano.

The people living on Mayotte, located between Madagascar and Mozambique off the coast of Africa, had been worried by seismic tremors for months. They were experiencing small earthquakes daily, Laure Fallou, a sociologist with the European-Mediterranean Seismological Centre in Bruyères-le-Ch tel, France, told Science. People “needed information,” she said. “They were getting very stressed, and were losing sleep.”

Maps of the seafloor showed a dramatic and recent change: a structure 800 meters high and 5 kilometers (3 miles) across had appeared on the ocean floor where there had been nothing before. A research team from the French National Center for Scientific Research (CNRS) were dispatched to investigate and placed six seismometers near the area of activity on the ocean floor, 3.5 kilometers (2 miles) beneath the surface.

Drug-resistant infections could be starved of nutrients using existing medicines

Posted by in categories: biotech/medical, futurism

Microorganisms like bacteria and fungi are increasingly becoming resistant to our best drugs, which is hurtling us towards a terrifying future where once-easily-treated infections become potentially life-threatening again. In a new approach to this problem, researchers from the University at Buffalo and Temple University have tested an alternative to antibiotics that uses existing drugs to starve a fungal infection of vital nutrients.
