Hand-knitted Molecules
Hand-knitted Molecules
Molecules are usually formed in reaction vessels or laboratory flasks. An Empa research team has now succeeded in producing molecules between two microscopically small, movable gold tips - in a sense as a "hand-knitted" unique specimen. The properties of the molecules can be monitored in real time while they are being produced.

Saturn hasn't always had rings
Saturn hasn’t always had rings
One of the last acts of NASA's Cassini spacecraft before its death plunge into Saturn's hydrogen and helium atmosphere was to coast between the planet and its rings and let them tug it around, essentially acting as a gravity probe. Precise measurements of Cassini's final trajectory have now allowed scientists to make the first accurate estimate of the amount of material in the planet's rings, weighing them based on the strength of their gravitational pull.

Thanks to rapid, 3D imaging, anyone can tour the fly brain
Thanks to rapid, 3D imaging, anyone can tour the fly brain
A new fly-through of the fly brain allows anyone to whizz past neurons and visit any of the 40 million synapses where neurons touch neuron. It's a super-resolution view of the complex network connections in the insect's brain that underlie behaviors ranging from feeding to mating. What's unprecedented, however, is that this 3D map over the whole fly brain, which shows details as small as 60 nanometers across, was captured in less than three days.

Mapping the brain at high resolution
New 3-D imaging technique can reveal, much more quickly than other methods, how neurons connect throughout the brain. Researchers have developed a new way to image the brain with unprecedented resolution and speed. Using this approach, they can locate individual neurons, trace connections between them, and visualize organelles inside neurons, over large volumes of brain tissue.

International collaboration publishes concept design for a post-LHC future circular collider at CERN
Geneva. Today, the Future Circular Collider (FCC) collaboration submitted its Conceptual Design Report (CDR) for publication, a four-volume document that presents the different options for a large circular collider of the future. It showcases the great physics opportunities offered by machines of unprecedented energy and intensity and describes the technical challenges, cost and schedule for realisation.

Measurement of five flashes from the depths of the universe
Measurement of five flashes from the depths of the universe
First-time precise measurement of gamma-ray bursts conducted successfully from a space station A detector called POLAR, developed at PSI, has been sent to outer space to collect data. In September 2016, the device was launched into Earth orbit on board the newest Chinese space station. From that vantage point, POLAR recorded so-called gamma-ray bursts flashing in the far reaches of the universe.

Team of telescopes finds X-ray engine inside mysterious supernova
Team of telescopes finds X-ray engine inside mysterious supernova
ESA's high-energy space telescopes Integral and XMM-Newton have helped to find a source of powerful X-rays at the centre of an unprecedentedly bright and rapidly evolving stellar explosion that suddenly appeared in the sky earlier this year. The ATLAS telescope in Hawaii first spotted the phenomenon, since then named AT2018cow, on 16 June.

More stable light comes from intentionally squashed quantum dots
Exploiting new 'strain engineering' approach produces highly stable, narrow linewidth light from individual quantum dots Novel colloidal quantum dots are formed of an emitting cadmium/selenium (Cd/Se) core enclosed into a compositionally graded CdxZn1-xSe shell wherein the fraction of zinc versus cadmium increases towards the dot's periphery.

Signatures of a 'messy' star that made its companion go supernova
Signatures of a ’messy’ star that made its companion go supernova
Many stars explode as luminous supernovae when, swollen with age, they run out of fuel for nuclear fusion. But some stars can go supernova simply because they have a close and pesky companion star that, one day, perturbs its partner so much that it explodes. These latter events can happen in binary star systems, where two stars attempt to share dominion.

Gaia reveals how Sun-like stars turn solid after their demise
Gaia reveals how Sun-like stars turn solid after their demise
Data captured by ESA's galaxy-mapping spacecraft Gaia has revealed for the first time how white dwarfs, the dead remnants of stars like our Sun, turn into solid spheres as the hot gas inside them cools down. This process of solidification, or crystallisation, of the material inside white dwarfs was predicted 50 years ago but it wasn't until the arrival of Gaia that astronomers were able to observe enough of these objects with such a precision to see the pattern revealing this process.

Shows single atoms can make more efficient catalysts
Detailed observations of iridium atoms at work could help make catalysts that drive chemical reactions smaller, cheaper and more efficient. Catalysts are chemical matchmakers: They bring other chemicals close together, increasing the chance that they'll react with each other and produce something people want, like fuel or fertilizer.

After mapping millions of galaxies, Dark Energy Survey finishes data collection
For the past six years, Fermi National Accelerator Laboratory has been part of an international effort to create an unprecedented survey of distant galaxies and better understand the nature of dark energy-the mysterious force accelerating the expansion of the universe. After scanning about a quarter of the southern skies over 800 nights, the Dark Energy Survey finished taking data on Jan.

Astronomers observe evolution of a black hole as it wolfs down stellar
Halo of highly energized electrons around the black hole contracts dramatically during feeding frenzy. On March 11, an instrument aboard the International Space Station detected an enormous explosion of X-ray light that grew to be six times as bright as the Crab Nebula, nearly 10,000 light years away from Earth.

Magnetar Mysteries in our Galaxy and Beyond
Magnetar Mysteries in our Galaxy and Beyond
In a new Caltech-led study, researchers from campus and the Jet Propulsion Laboratory (JPL) have analyzed pulses of radio waves coming from a magnetar-a rotating, dense, dead star with a strong magnetic field-that is located near the supermassive black hole at the heart of the Milky Way galaxy. The new research provides clues that magnetars like this one, lying in close proximity to a black hole, could perhaps be linked to the source of "fast radio bursts," or FRBs.

Citizen scientists help discover new exoplanet in ’habitable zone’
A new planet roughly twice the size of Earth has been discovered located within the "habitable zone"-the range of distances from a star where liquid water may exist on the planet's surface. A research team that included a UChicago graduate student confirmed the finding after volunteer citizens flagged a crucial piece of evidence in data from NASA's Kepler spacecraft.
