Spiders develop an incredible way of hearing sounds | Digital Trends Spanish

A group of researchers at Cornell University discovered that ogre-faced spiders, named for their large eyes, have incredible night vision and are also capable of hearing their prey and predators. According to the research, which was published in Current Biology, these spiders use hairs and receptors on their legs to pick up sounds from at least two meters away. In this way they could detect low-frequency sounds coming from their prey, such as insects, as well as high-frequency sounds from predators such as birds. How did they find out? The scientists also found that, in addition to trapping prey on the ground, these arachnids are capable of grasping insects in the air, which does not appear to be related to their vision. In fact, to prove it, the researchers put dental silicone ov...

Rare Ancient Creatures Keys to Explaining Evolution | Digital Trends Spanish

An article published in Nature explains in detail how some of the oldest and most unique species provide relevant information that allows the evolution of animals to be rewritten. One of the oldest known, the Yilinga spiciformis, evidence that some animal traits appeared five hundred million years ago. When it was found last year in China, they found tracks left by this creature, which has allowed us to know about the movement it made. In fact, many call this creature "the first walker." In the same region where it was discovered, the researchers found two parallel rows of dimples. They believe they were made by an animal 550 million years ago that might be capable of burrowing and possessed multiple pairs of appendages. This would make it one of the first known animals with legs...

Maduro assures that Venezuela found the cure for COVID-19 | Digital Trends Spanish

The president of Venezuela, Nicolás Maduro, assured that the Venezuelan Institute of Scientific Research (IVIC) found a molecule called TR-10 that supposedly would kill one hundred percent of the coronavirus. "Venezuela has achieved a medicine that cancels 100% the coronavirus," said the president through state television VTV, also ensuring that it is "the cure." Maduro also stated that the medicine would act without any type of toxicity or side effects. The molecule was isolated and confronted with SARS-CoV-2 in a study that lasted six months and resulted in the complete annihilation of the virus, according to the Bolivarian's own statements. Thus, Maduro was optimistic that the studies will soon be ratified by the World Health Organization in order to begin mass production of thi...

Y chromosome explains male reactions to disease | Digital Trends Spanish

An important study carried out by researchers at the Montreal Clinical Research Institute proposes that the Y chromosome, typical of men, would be responsible for why they suffer from certain diseases differently than women, including COVID-19. The results of the study were published this month in Nature by University of Montreal professor Christian Deschepper, director of the Experimental Cardiovascular Biology research unit at the Montreal Institute of Clinical Research. "Our discovery provides a better understanding of how male Y chromosome genes allow male cells to function differently from female cells," explained the author according to an article by EurekAlert!. "In the future, these results could help shed some light on why some diseases occur differently in men...
