For decades, the growth of artificial intelligence has fascinated scholars and scientists alike. Today, intelligent machines aid and streamline our lives, but the next fifty or a hundred years may yield even more powerful AI, which could elevate or transform our species. If humans do create sophisticated, super-intelligent machines, how will the growth of artificial intelligence affect the future of humanity?

Although oxygen is now the most abundant element in our oceans and our atmosphere, comprising about 88.8 percent and 23.1 percent of the mass of the two, respectively, this wasn’t always the case. In actuality, the abundance of oxygen on Earth arose only 2.4 billion years ago thanks to the advent of photosynthesis, the process through which some of the first life-forms transformed sunlight into energy. It was only coincidence, scientists say, that one of the products of this process was oxygen. But it also would go on to completely transform the planet, creating the conditions for increasingly complex forms of life.

For all the importance of this so-called “Great Oxidation Event,” scientists have always wondered about the presence of oxygen on the planet prior to the emergence of photosynthesis.

The formation of amyloid plaques in the brain is a hallmark of Alzheimer’s disease. But drugs designed to reduce accumulations of these plaques have so far yielded, at best, mixed results in clinical trials.

Yale researchers have found, however, that swelling caused by a byproduct of these plaques may be the true cause of the disease’s debilitating symptoms, they report Nov. 30 in the journal Nature. And they identified a biomarker that may help physicians better diagnose Alzheimer’s and provide a target for future therapies.

Researchers at Uppsala University have formulated a new model for our universe to solve the mystery of dark energy. The study proposes a new way to assemble a dark energy cosmos where our universe rides on an expanding bubble in an extra dimension. In a study, Swedish physicists pointed out the existence of another dimension in the universe we live in. Scientists propose that our universe exists within an expanding bubble in an extra dimension. Studying the cosmos in the last 20 years has shown that the cosmos is constantly expanding. Additionally, the speed of its expansion increases.

The conventional explanation for this goes through a type of energy (dark energy), which permeates everything and “pushes” the universe to expand more and faster. In physical cosmology and astronomy, dark energy is a still-unknown form of energy that is hypothesized to permeate all of space, tending to accelerate the expansion of the cosmos The mysterious dark energy poses more questions than answers, functioning as a cosmic wildcard in some explanations of theoretical physics.

Researchers from the University of Uppsala have proposed a new concept. This includes another dimension and other universes to avoid this problem. In their study, published in the journal Physical Review Letters, physicists from Uppsala University argue that our universe is “mounted” on a bubble that expands in an additional dimension. Our entire universe fits on the edge of the expanding bubble. All matter in our cosmos corresponds to the endpoints of strings that extend into the extra dimension. The researchers also show that expanding bubbles of this kind can be created within the string theory framework.

A new study that analyzed new data segments suggests there are around 300 million habitable planets in our Milky Way Galaxy alone.

A bizarre, volcanic comet has violently erupted, spewing out more than 1 million tons of gas, ice and the “potential building blocks of life” into the solar system.
