The mad hatterpillar These caterpillars are native to Australia and eat eucalyptus trees. Why do they build themselves a hat? No one really seems to know why the caterpillars keep their old heads hanging around. Bug Girl’s Blog When Cleaning fMRI Data is a Nuisance A flaw in data processing could be leading to biases […]

Hope springs eternal: “Pandora’s Promise” and the truth about nuclear energy So why would environmentalists of all people support nuclear power? What changed these people’s minds? Two things, primarily. The Curious Wavefuntion Making and Breaking Compulsive Behaviour When scientists have scanned the brains of people with obsessive-compulsive disorder, they’ve seen more neural activity in areas […]

Have you ever observed how a drop of coffee dries? As water evaporates, its suspended particles are deposited in a ring-like fashion in a phenomenon known as the coffee-ring effect. Obviously, this effect is undesirable in the numerous practical applications that require a uniform coating. However, the way to avoid it has remained unknown. The […]

Just a few years ago, nanoparticles broke into almost every laboratory in the world in one way or another. It marked a boom in nanoscience and nanotechnology. The demand for these new ultrafine particles, halfway between the bulk scale and the molecule scale, increased in such a way that sometimes there was even a shortage […]

Graphene shown to produce ultrashort laser pulses Researchers have discovered that graphene can absorb light over a broad range of wavelengths, allowing it to be used to create ultrashort laser pulses of color. The discovery could mean that graphene, a thin, strong conductive material, could be used to create small, economical ultrashort-pulse lasers used in […]

Some years ago, with a sudden and drastic reduction on the number of honeybees, scientists realized that if these insects disappeared it would be the end of agriculture as we understand it, as they are the main drivers of agricultural pollination in the US . But would we be able to replace these pollinators with […]

Quantum computing is one of the most interesting fields of study nowadays, both from theoretical and pragmatic point of views. A universal quantum computer can potentially solve certain problems, as factorizing numbers, much faster and with fewer resources than a classical one . This developing technology is based on the use of quantum mechanics as […]

Competing gravity of galactic clouds probably caused band of gas A gravitational tug-of-war between the Large Magellanic Cloud and the Small Magellanic Cloud may be responsible for the huge ribbon of gas at the halo of the Milky Way. Astronomers in the U.S. and Germany measured how much oxygen and sulphur there is in the […]

“Junk” DNA in plants not needed to remain healthy So-called junk DNA is just that — junk, according to a study by researchers at the University of Buffalo in New York. In a study of the carnivorous bladderwort plant, they found that the part of the genome not responsible for coding proteins in plants is […]

Maples rely on wind, upward currents, and gusts to spread their seeds over long distances that can reach several kilometers. Maple seeds are able to autorotate because their center of gravity, determined by the position of the nut, is located at the base of the wing-shaped seed. It has been observed that, despite their small […]
