Quantum entanglement is the theory that particles can be connected in such a way that measuring one particle can instantaneously convey information about that measurement to the other particle, regardless of the distance between them. It almost sounds like magic, which is probably why it received a healthy dose of criticism from the physics community when the theory was first proposed nearly 100 years ago.

Albert Einstein was a particularly vocal critic of entanglement, which he famously described as “spooky action at a distance.” Part of Einstein’s beef with the quantum mechanics crowd was that he believed that particles have definite qualities that exist before they are measured and that two particles distant in space and time can’t affect one another instantaneously since they are limited by the speed of light—a viewpoint known as local realism.

Under quantum mechanics, however, the properties of a particle don’t exist independently of measurement used to determine those properties. Moreover, when it comes to entangled particles, the measurement of one particle will instantaneously influence the properties of the other entangled particle. This means that the values of these properties will be highly correlated—so highly correlated, in fact, that the degree of coincidence in their values can’t really be explained without recourse to quantum mechanics.

Today, the Earth is covered with life in countless forms, but four billion years ago there was no life on our rocky world. So, it stands to reason that sometime between then and now a single organism came into existence that started it all. This is a widely-held belief among scientists, and the name they have given that ancient organism is LUCA. It stands for “last universal common ancestor” — the one microbe that you, your dog, the guy who cut you off in traffic this morning, and the tree in your back yard all descended from.

It’s a mind-blowing concept. It makes perfect sense, but tracing the origins of the ancestor of all life on Earth is an incredibly difficult task. For a long time, scientists had settled on a timeline of between 3.5 billion and 3.8 billion years ago. Now, a new round of research has pushed that date back even further. The work was published in Nature Ecology & Evolution.

It’s important to note that LUCA isn’t thought to have been the very first cellular organism on Earth. The conditions under which life formed likely created many single-celled life forms, but only one of them had what it takes to “make it” on Earth, and that microbe is believed to be the root of everything that came later.

Garbage has never smelled so sweet for a small village in southern Benin since it opened a pilot waste treatment centre to turn household rubbish into gas—and cash.

“Our trash has become gold. We no longer throw it into the bush. We use it to make money,” beams Alphonse Ago, who lives next to the centre in Houegbo village.

ReBin, a Swiss foundation for sustainable development, built the 1.3-hectare (3.2-acre) facility, which every week turns around six tonnes of organic waste into 200 cubic metres of biogas—saving some 164 tonnes of wood from being used to make charcoal.

Healthy diet linked to healthy aging and longer telomeres, a new study on 5000 healthy adults. Relationship significant in women. … All four diets emphasize eating plenty of fruits, vegetables, whole grains and plant-based protein and limiting consumption of sugar, sodium and red and processed meat. Overall, the findings suggest that following these guidelines is associated with longer telomere length and reduces the risk of major chronic disease…”

Eating a diet that is rich in fruits, vegetables and whole grains and low in added sugar, sodium and processed meats could help promote healthy cellular aging in women, according to a new study published in the American Journal of Epidemiology.

“The key takeaway is that following a healthy diet can help us maintain healthy cells and avoid certain chronic diseases,” said lead author Cindy Leung, assistant professor of nutritional sciences at the University of Michigan School of Public Health. “Emphasis should be placed on improving the overall quality of your diet rather than emphasizing individual foods or nutrients.”

A new study showed physical activity might lower cardiovascular disease risk by improving blood vessel function.

Adults in their early 60s, who spend less time sitting and more time engaged in light to vigorous physical activity, benefit with healthier levels of heart and vessel disease markers, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

The results from increased physical activity were found to be particularly good among women.

Russia’s most famous weapons manufacturer has unveiled a 13ft tall walking killer robot operated by pilots who sit inside it.

Kalashnikov Concern presented the state-of-the-art bulletproof robot along with utility vehicles and new assault rifles at the Army 2018 fair at the Patriot Park just outside Moscow.

Facebook won’t tell you exactly why it does or doesn’t trust you.

Facebook revealed this week it’s trying to stem the flow of fake news by assigning trust values to users. It insists on keeping its criteria for trustworthiness secret though, in case untrustworthy people try to game the system — and they almost certainly will.

Tessa Lyon, Facebook‘s product manager, told The Washington Post a bit more about the system, in which the company uses several flags to identify which people on the site are more trustworthy than others. It rates users on a scale of zero to one. The only judging metric she would admit to is a person’s history of reports.

Billionaires have the money to make things happen. The ultra rich individuals on this list for the most part have two main subjects on their mind: space travel and immortality. Almost all the ideas appear to be for the benefit of mankind.

If you had a spare US$1 billion or US$100 billion, what would you spend your money on? These men could have anything in the world, but they want more as they push the boundaries of health, science and infrastructure.

One of the most significant AI milestones in history was quietly ushered into being this summer. We speak of the quest for Artificial General Intelligence (AGI), probably the most sought-after goal in the entire field of computer science. With the introduction of the Impala architecture, DeepMind, the company behind AlphaGo and AlphaZero, would seem to finally have AGI firmly in its sights.

Let’s define AGI, since it’s been used by different people to mean different things. AGI is a single intelligence or algorithm that can learn multiple tasks and exhibits positive transfer when doing so, sometimes called meta-learning. During meta-learning, the acquisition of one skill enables the learner to pick up another new skill faster because it applies some of its previous “know-how” to the new task. In other words, one learns how to learn — and can generalize that to acquiring new skills, the way humans do. This has been the holy grail of AI for a long time.
