Taking the carnivorous plant Nepenthes as a model, scientists at Harvard University have developed a material that repels any type of liquid, including blood and oil. This bio-inspired liquid repellency technology, unveiled in the latest issue of Nature, could have application in the transport of biomedical fluids, the handling of fuels or the manufacture of antifreeze.

Using 3D computer simulations of basketball free throw trajectories, Chau Tran and Larry Silverberg of North Carolina State University (USA) have discovered how to shoot the ball with the highest hit rate.

A British cesium clock that marks the atomic time is now the most accurate long-term time meter in the world, according to a new evaluation of the clock to be published in the international scientific journal 'Metrology' and conducted by physicists at the National Physical Laboratory. (NPL) in the United Kingdom and Pennsylvania State University in the United States. The watch belongs to a group of elite cesium clocks, created by time laboratories in Europe, the United States, and Japan, as their national frequency standard for measuring time.

Sometimes the simplest of things becomes extremely complex when you look closely. For example, how many times have you turned a sheet of paper into a sphere before throwing it in the trash can? Have you ever wondered what mechanism we use to turn a simple sheet of paper into that resistant ball? Two physicists from the University of Massachusetts, Narayan Menon and Anne Dominique Cambou, have asked themselves this question.

It is the one that is used as a means of recording and disseminating reality, and constitutes a work element to communicate science. Depending on the size of the resulting image in relation to the size of the object, we distinguish between photomicrography and photomicrography.

Yes. In 2009, through an Atomic Force Microscope (AFM), scientists at the IBM laboratory in Zurich (Switzerland) were able to visualize for the first time the atoms that make up a molecule. In Kharkov, Ukraine, he went one step further and got a direct look at the structure of a single atom, proving many assumptions of quantum physics.

The truth is that no. Sea water contains large amounts of salt (sodium chloride), specifically more than 10 grams per liter if we take the average of all the world's oceans. The molecules of ordinary soap are made up of sodium atoms bound to fatty acids.

Astrophysicists have discovered a thin band of antiprotons that envelop the Earth. The astonishing finding, described in the 'Astrophysical Journal Letters', confirms the theory that predicts that the magnetic field of our planet could trap antimatter.
