Evidence of ancient flood uncovered in China Scientists have uncovered evidence that the myth that an enormous flood spawned China’s Xia dynasty isn’t just legend. Geologists, historians and archaeologists worked together to determine a massive flood occurred around 1,922 B.C., around the time Emperor Yu is said to have founded civilization in China. The Washington […]

The human microbiota is the community of microorganisms that resides in our body. They are found in a number of organs and biofluids, including the skin, mammary glands, placenta, seminal fluid, uterus, ovarian follicles, lung, saliva, oral mucosa, and conjunctiva, but the most abundant group resides in the gastrointestinal tract. This complex community has been […]

Improvisation is a hallmark of jazz music, arguably its most salient feature. When they improvise, musicians compose and play simultaneously, one of the most notorious examples of spontaneous creativity. What happens in the brain during improvisation is largely a mystery, but studying it may help us gain some insight on the basis that underlie the […]

Cancer found in bone of ancient human ancestor Evidence of cancer has been found in the toe bone of an ancient human ancestor who died 1.6 million to 1.8 million years ago, suggesting the deadly disease isn’t just caused by lifestyle factors. Researchers examining the bone using 3D imaging identified a malignant osteosarcoma tumor. National […]

Graphene is a two-dimensional allotrope of carbon made of hexagons. In February 2015, penta-graphene, only made of pentagons, was theoretically proposed as another two-dimensional allotrope of carbon . Apparently, it is dynamically, thermally, and mechanically stable, exhibiting a large band gap (graphene is gapless). However, an exhaustive experimental search has been inconclusive, resulting in doubts […]

Ultra-sensitive detector fails to find sign of dark matter The most sensitive search yet for dark matter has failed to turn up a signal from the elusive material believed to make up most of the universe’s mass, according to findings presented at the 11th Identification of Dark Matter Conference in the UK. The experiment pushed […]

«Mosquito» is one of the few words, together with «guerrilla», «adobe», «cigarrillo» and some others that Spanish culture has brought to other languages. I am not sure whether we should be proud of this legacy. The «little fly» is one of humanity most dangerous and terrible enemies. Many species of mosquitoes act as vectors of […]

Agriculture may have had many roots, DNA study suggests The skeletons of four ancient farmers have been found in Iran, and DNA tests indicate they have no genetic links to Aegeans, long thought to be the first farmers in Europe, which suggests that agriculture may have been developed more than once. DNA analysis of the […]

Everybody knows the force that is required to activate a light switch on a wall – a finger is enough. But how much force do you need to apply if the device was dramatically reduced to the “nanoscale world”, that is, how much force do you need to operate a “single-molecule switch”? This fundamental question […]
