Phys.org / Rare 'firework morphology' of supernova remnant Pa 30 may be due to white dwarf wind

In 1181 AD, a bright "guest star" was observed to linger in the sky for around six months. Nearly 850 years later, the likely remnants of this event were rediscovered and tentatively linked to the 1181 supernova and dubbed ...

Phys.org / Mass spec innovation uses 'bin' sorting to detect overlooked molecules

Weight says a lot. In the kitchen, it could mean cooking with too little or too much of an ingredient. For scientists, a molecule's weight can help determine its makeup. This, in turn, can shed light on whether a potential ...

Phys.org / How a biological version of rock-paper-scissors determines if lizard colors are maintained or lost

Two new studies into lizard colors reveal how one species maintains its colorful diversity while others are losing their ancient colors. And the changes are being driven by the biological equivalent of rock-paper-scissors.
