Thermodynamic Magic Enables Cooling without Energy Consumption
Physicists at the University of Zurich have developed an amazingly simple device that allows heat to flow temporarily from a cold to a warm object without an external power supply. Intriguingly, the process initially appears to contradict the fundamental laws of physics. If you put a teapot of boiling water on the kitchen table, it will gradually cool down.

First results from the ExoMars Trace Gas Orbiter
10 April 2019 New evidence of the impact of the recent planet-encompassing dust storm on water in the atmosphere, and a surprising lack of methane, are among the scientific highlights of the ExoMars Trace Gas Orbiter's first year in orbit. Two papers are published in the journal Nature today describing the new results, and reported in a dedicated press briefing at the European Geosciences Union in Vienna.

Wonder material: individual 2D phosphorene nanoribbons made for the first time
Tiny, individual, flexible ribbons of crystalline phosphorus have been made and measured an international collaboration, in a world first, and they could revolutionise electronics and fast-charging battery technology. Since the isolation of 2-dimensional phosphorene (the phosphorus equivalent of graphene) in 2014, more than 100 theoretical studies have predicted that new and exciting and properties could emerge by producing narrow ‘ribbons' of this material.

Detecting pollution with a compact laser source
Researchers at EPFL have developed a simple mid-infrared laser source that can be used to detect pollution in the air or molecules in someone's breath. Their system takes up considerably less space than the large ones typically used for such tasks. Researchers at EPFL have come up with a new middle infrared light source that can detect greenhouse and other gases, as well as molecules in a person's breath.

Black nanoparticles slow the growth of tumors
The dark skin pigment melanin protects us from the sun's damaging rays by absorbing light energy and converting it to heat. This could make it a very effective tool in tumor diagnosis and treatment, as demonstrated by a team from the Technical University of Munich (TUM) and Helmholtz Zentrum München.

Novel nanophotonic chips for encrypted data transfer: Quantum communication
A giant cylindrical refrigerator, an electron-beam pattern generator, a cleanroom, etching equipment. Sometimes it takes a lot of big things to make something very small. The nanoscientists at the University of Münster headed by Prof. Wolfram Pernice and Prof. Carsten Schuck know this only too well: they use these and other devices to produce nanophotonic chips the size of a one-cent piece.

Harnessing photonics for at-home disease detection
With nothing more than a photonic chip and an ordinary camera, EPFL researchers have managed to count biomolecules one by one in a small sample and determine their position. Their tiny device - a marriage of optics and smart image analysis - is even able to detect a graphene sheet only a single atom thick.

Scientists climb UChicago buildings to study air quality and pollution
The bell tower of Rockefeller Memorial Chapel is normally populated by tourists and the University's carillonneur. But scientists recently scaled its 271 stone steps to the highest point on campus in order to study air quality and pollution across Chicago. At Rockefeller, researchers from UChicago and Harvard University ran a long tube down the stone tower to a humming machine, which analyzed air for methane as it blew past the tower.

Scientists invent way to trap mysterious ’dark world’ particle at Large Hadron Collider
Now that they've identified the Higgs boson, scientists at the Large Hadron Collider have set their sights on an even more elusive target. All around us is dark matter and dark energy-the invisible stuff that binds the galaxy together, but which no one has been able to directly detect. "We know for sure there's a dark world, and there's more energy in it than there is in ours," said LianTao Wang, a University of Chicago professor of physics who studies how to find signals in large particle accelerators like the LHC.

10 ways SLAC’s X-ray laser has transformed science
Share This Article Electrons accelerated by SLAC's linear accelerator enter the LCLS undulator hall and run a gauntlet of 32 powerful undulators. Each undulator contains 224 magnets whose alternating poles force the electrons to zigzag violently and radiate X-rays. By the time they leave the undulator hall, the X-ray laser pulses are a billion times brighter than beams from traditional synchrotron X-ray sources, opening a new realm of possible experiments and discoveries.

In quantum breakthrough, scientists demonstrate ’one-way street’ for energy flow
A basic rule in our lives is that if energy can flow in one direction, then it can also flow in the reverse direction. For example, if you open a window and yell at someone outside, you also can hear if they yell back. But what if there was a way to create a "one-way street" for mechanical energy that only allows heat and sound to flow in one direction?
