Invisibilidade do espaço

Os carros já podem ser recarregados à dist ncia, seja na garagem ou na estrada, mas recarregar celulares e outros aparelhos sem fios ainda exige que eles sejam colocados sobre uma base apropriada.

Mas uma solução já está à vista, e poderá permitir que os celulares sejam recarregados sem que nem mesmo precisem ser retirados do bolso.

In the last few years, hundreds of contained “nano” satellites known as CubeSats have been launched in low Earth orbit for many purposes, including for collecting targeted scientific data. Federal agencies such as NASA and the National Science Foundation are exploring the potential of these highly affordable satellites in advancing research goals.

A new report from the National Academies of Sciences, Engineering, and Medicine concludes that CubeSats have demonstrated usefulness for scientific data gathering and can also augment – but not replace — the capabilities of large satellite missions and ground-based facilities. The report identifies examples of high-priority science goals that could be pursued through the use of CubeSats in areas such as solar and space physics, planetary science, and Earth science.

In order to continue building the capabilities of CubeSats for research, federal support is crucial, the report says, which identifies several steps NASA and NSF should take to ensure that CubeSats reach their full potential.

Scientists from ITMO University and Trinity College have designed an optically active nanosized supercrystal whose novel architecture can help separate organic molecules, thus considerably facilitating the technology of drug synthesis. The study was published in Scientific Reports (“Chiral quantum supercrystals with total dissymmetry of optical response”).

The collapse of a trapped ultracold magnetic gas is arrested by quantum fluctuations, creating quantum droplets of superfluid atoms.

Macroscopic implosions of quantum matter waves have now been halted by quantum fluctuations. The quantum wave in question is an atomic Bose-Einstein condensate (BEC), a quantum state with thousands to tens of millions of atoms in an ultracold gas all sharing the same macroscopic wave function. Attractive atomic interactions can cause BECs to collapse in spectacular ways, in what’s been termed a “bosenova,” a lighthearted allusion to a supernova explosion [1]. Tilman Pfau and colleagues from the University of Stuttgart, Germany, have shown that for BECs made of dysprosium, whose bosonic isotopes are among the most magnetic atoms in the periodic table, long-range dipole-dipole interactions between these neutral atoms create a totally new phenomenon: the arrested collapse of a quantum magnetic fluid, called a quantum ferrofluid [2, 3]. Such a ferrofluid relies crucially on the strong dipolar interactions in the dysprosium gas.
