Our metastable universe Under the simplest assumptions, the measured mass of the Higgs could mean the universe is eventually unstable and destined to fall apart. Scientific American Could flow batteries back up electric grids? To power flow batteries, two aqueous electrolytes held in different tanks are pumped through a membrane into a separate chamber, causing […]

Bat-eating spiders are more common than you think Bat-eating spiders are more common in the world than once believed. These spiders are found on all continents except Antarctica. Almost 90% of the web-building spider and tarantula species live in warmer climates, and can capture bats both with and without a web. LiveScience Nyffeler M, Knörnschild […]

Thin films are defined as material layers ranging from nanometers to several micrometers of thickness that are deposited onto a matrix in order to modify its physical characteristics. Although solar cells conform a relevant field of application, it may be highlighted that the most important employment of thin film technology lies in the semiconductor industry […]

3-body problem gets 13 more possible solutions Scientists have come up with 13 new solutions to the “three-body problem,” a situation in which three objects orbit each other in a pattern. The discoveries, which will help astrophysicists further understand planetary systems, brings the total number of solutions to 16. Science now Milovan Šuvakov, V. Dmitrašinović […]

Bunnies implicated in the demise of Neanderthals in Iberia Excavations are shedding light on what might have been a significant factor in the demise of the Neanderthal: the inability to hunt small game. The remains of large animals are prevalent in Neanderthal cave excavations, but the bones of smaller animals such as rabbits were prevalent […]

It is well known that an accurate and energetic laser shot can melt, ionize and excite the material in which the light is focused, creating very bright plasmas after the interaction. Valuable information can be obtained from the light emitted by the plasma, such as the elemental composition of the material itself or the environment […]

Zircon grains came from ancient continent Grains of zircon found on the island of Mauritius may have come from the crust of an ancient continent beneath the Indian Ocean. The grains formed almost 2 billion years ago, but the island is only 65 million years old. New Scientist Trond H. Torsvik, Hans Amundsen, Ebbe H […]

You have probably heard of the plastic island , an enormous area full of plastic garbage, gathered by oceanic currents, in the North Pacific Ocean. In the last few decades the amount of plastic debris in this area has increased two orders of magnitude, representing one of the best examples of the environmental impact caused […]

“Native” water once existed on the Moon A new analysis of lunar soil samples from NASA’s Apollo missions has found evidence that the moon in its early days may have contained “native” water. The findings, which were published in the journal Nature Geoscience, go against prevailing theories that the moon formed from the debris of […]

Humans can build and use the most sophisticated tools. One of the reasons is the configuration of our hands, which enable us to hold items in a very convenient way. But further than that, we can actually grab items because of the friction coefficient that exists between the skin of our hands and the surface […]
