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 / Orange pigments in birds and human redheads prevent cellular damage, study shows
A pigment that makes feathers and hair orange helps prevent cellular damage by removing excess cysteine from cells. Pheomelanin is an orange-to-red pigment that is built with the amino acid cysteine and found in human red ...
Phys.org / Ancient clay cylinders provide first foundation text documenting Nebuchadnezzar II's restoration of the ziggurat of Kish
In 2013, two local Iraqis handed over two inscribed clay cylinders to the State Board of Antiquities and Heritage. Subsequent analysis and translation of the inscriptions published in Iraq revealed them to belong to King ...
Phys.org / Jupiter's moon Europa lacks the undersea activity needed to support life, study suggests
The giant planet Jupiter has nearly 100 known moons, yet none have captured the interest and imagination of astronomers and space scientists quite like Europa, an ice-shrouded world that is thought to possess a vast ocean ...
Phys.org / Solving quantum computing's longstanding 'no cloning' problem with an encryption workaround
A team of researchers at the University of Waterloo have made a breakthrough in quantum computing that elegantly bypasses the fundamental "no cloning" problem. The research, "Encrypted Qubits can be Cloned," appears in Physical ...
Phys.org / Astronomers build molecular cloud atlas for nearby Andromeda galaxy
Astronomers from Cardiff University, UK, have employed the Combined Array for Research in Millimeter-wave Astronomy (CARMA) to explore the nearby Andromeda galaxy. Results of the observational campaign, published December ...
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.
Phys.org / Why we trust romantic partners rather than AI when making big financial decisions
Artificial intelligence programs are not only helping us tackle complex challenges like diagnosing diseases and predicting weather patterns, but also assisting with more mundane matters such as correcting grammar and planning ...
Phys.org / Blazar Ton 599's complex variability investigated by long-term observations
Using the Whole Earth Blazar Telescope (WEBT), an international team of astronomers have performed long-term photometric observations of a luminous blazar known as Ton 599. Results of the observations, published in the Astronomy ...
Phys.org / AMOC collapse simulations reveal what could happen to the ocean's carbon
The Atlantic Meridional Overturning Circulation (AMOC) is the system of currents responsible for shuttling warm water northward and colder, denser water to the south. This "conveyor belt" process helps redistribute heat, ...
Phys.org / New framework unifies space and time in quantum systems
Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space and time has remained fundamentally disconnected. Relativity unifies space and time into a single ...
Phys.org / The book only gets 3 stars... but is considered great literature
A new study from Aarhus University shows that star ratings of books are not always accurate. Average ratings on Goodreads can hide both literary classics and highly divided reading experiences—and can therefore be a misleading ...
