NASA’s new Transiting Exoplanet Survey Satellite (TESS) is designed to ferret out habitable exoplanets, but with hundreds of thousands of sunlike and smaller stars in its camera views, which of those stars could host planets like our own?

TESS will observe 400,000 stars across the whole sky to catch a glimpse of a planet transiting across the face of its star, one of the primary methods by which exoplanets are identified.

A team of astronomers from Cornell University, Lehigh University and Vanderbilt University has identified the most promising targe...

CRISPR-chip enables Digital Detection of DNA without Amplification

Kiana Aran’s novel system immobilizes the CRISPR complexes on the surface of graphene-based transistors. These complexes search a genome to find their target sequence and, if the search is successful, bind to its DNA. This binding changes the conductivity of the graphene material in the transistor, which detects the change using a handheld reader.

Icy Giant Planets in the Laboratory

Even under extremely high pressure, such as those in the interior of Neptune or Uranus, there are stable crystal structures of carbon (orange) and hydrogen (gray). This discovery by HZDR researchers reveals new possibilities for the inner structure of the ice giants.

Researchers use plastics to better understand what happens inside planets. Giant planets like Uranus and Neptune may contain much less free hydrogen than previously assumed. Researchers from the German Helmholtz-Zentrum Dresden-Rossendorf (HZDR) drove shock waves through two different types of plastic to reach the same temperatures and pressures present inside such planets, and observed the behavior using ultra-strong X-ray laser pulses...

Engineers demonstrate Metamaterials that can Solve Equations


University of Pennsylvania Engineers have designed a metamaterial device that can solve integral equations. The device works by encoding parameters into the properties of an incoming electromagnetic wave; once inside, the device’s unique structure manipulates the wave in such a way that it exits encoded with the solution to a pre-set integral equation for that arbitrary input.
