The future of ultrashort laser pulses

Searching for water in the Milky Way, drier than first thought

The Hubble Space Telescope finished another step in a important mission, looking for water in the milky way. The results so far are a bit surprising, with three exoplanets (planets outside the solar system) coming up short in their water supplies. (Credit: Greg Bacon)

Neck of Rosetta’s ‘rubby duckie’ comet shows a bright ring

Rosetta imaged its target comet, Comet 67P/Churyumov-Gerasimenko, from about 3,417 miles (5,500 kilometers) away. The “neck” of the comet appears to be brighter than the rest of the nucleus. (Credit: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA)

Higgs and top: a new window on dark matter

Fig. 1. Left: Limits on the dark-matter particle mass as a function of the effective interaction scale from the associated production of the particle with a top-quark pair. Fig. 2. Right: The limits set on the dark-matter particle mass from the search for invisible Higgs-boson decays compared with those from direct-detection experiments. — Fig. 1.

Unleashing the power of quantum dot triplets

One approach of making computers faster relies on quantum dots, a kind of artificial atom, easily controlled by applying an electric field. A new study demonstrates that changing the coupling of three coherently coupled quantum dots with electrical impulses can help better control them. (Credit: Tooski, S. B. et al.)

Still confused about quantum computing? This may help

There’s nothing like a Star Trek reference (yay Tribbles!) to help explain complex stuff like quantum computing. (Credit: Microsoft, Michael-Freedman)
