In the past entry we examined how “out-of-body experiences” (OBEs) might have an influence in the belief in a “soul” separated from the body. Now we shall take a look to the other two types of “abnormal” psychological experiences […]

How neural network guides autonomous car’s turns
An autonomous car was trained to negotiate high-speed turns without losing control. A neural network based on more than 200,000 motion samples of driving on various surfaces at high speeds was used in […]

The so-called van der Waals materials consist of two-dimensional layers bound by weak van der Waals forces. After the isolation of graphene, the field of two-dimensional van der Waals materials has experienced an explosive growth and new families of […]

During the second half of the 80s, when no one knew those years would become the Soviet Union’s last, Mikhail Gorbachev attempted some economic reforms without much success. Less than one decade earlier, in 1978, Deng Xiaoping started a series […]

Black holes are vacuum solutions of the Einstein equation. Hence, the energy-momentum tensor for a black hole is null at every point of space. The only place where its mass can be located is where there is no space, i.e., […]

Sun bears communicate via facial mimicry
Sun bears communicate by mimicking each other’s facial expressions, a practice long thought to occur only in species with complex social systems. “Other primates and dogs are known to mimic each other, but only […]

Controlling electron waves by harnessing phase-coherence and interference effects is a cornerstone for future nanoelectronics or quantum computing. To this end, design of platforms with well-defined, narrow, and low-loss propagation channels is essential. Nanoporous graphene (NPG) holds great potential for […]

The division of past and future
In Part 1 of this series, we presented the empirical fact that under extreme circumstances, a certain observer’s past can be in another observer’s future. To explain this, we introduced the network of […]

The idea that human beings are composed by two kind of ‘substances’, a material body and a spiritual mind, or soul, is probably as old as modern human beings, and has certainly insufflated most of the world religions, as well […]

Hormonal birth control failure might be due to genetic mutation
The reason hormonal birth control methods aren’t 100% effective, even in compliant patients, may be due to a genetic mutation in some women. Researchers say about 5% of women are […]
