Phys.org / TESS discovers a super-Earth exoplanet orbiting nearby star
Using the Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new super-Earth exoplanet orbiting a star located about 83 light years away. The newfound alien world is slightly larger than Earth and ...
Phys.org / ATCA observations probe peculiar pulsar wind nebula Vela X
Astronomers have employed the Australia Telescope Compact Array (ATCA) to investigate a peculiar pulsar wind nebula known as Vela X. Results of the new observations, published March 2 on the arXiv pre-print server, provide ...
Phys.org / Archaeologists untangle how Bronze Age textiles were made
Analysis and reconstruction of a warp-weighted loom from the second millennium BC site of Cabezo Redondo, Spain, provides an unprecedented glimpse into the development of textile technology in the Bronze Age western Mediterranean.
Phys.org / Rising seas threaten barrier islands, but seabird guano could speed recovery
Birds that live and breed in vegetated coastal areas, such as dunes and small islands, not only build nests but also—unintentionally—shape their own surroundings. This was discovered by Utrecht-based Earth scientist Floris ...
Phys.org / Dry ice detected in a planetary nebula for the first time
An international team of astronomers has employed the James Webb Space Telescope (JWST) to observe a complex planetary nebula known as NGC 6302. The observations, detailed in a paper published Feb. 25 on the arXiv pre-print ...
Phys.org / Enhanced fluorescence technique illuminates rapid, coordinated protein folding
A team of US researchers has gained new insights into how large protein molecules consistently fold themselves into useful shapes. Using a new approach to fluorescence microscopy, Hoi Sung Chung and colleagues at the National ...
Phys.org / Tsunami risks in the Mediterranean: Why Nice should prepare an evacuation plan
The Mediterranean Sea is widely perceived as having a low tsunami risk. History and recent modeling technology have demonstrated that destructive waves have already hit the French coast and could do so again. The results ...
Phys.org / Deep-sea natural compound targets cancer cells through a dual mechanism
A collaborative research team has uncovered a previously unknown mechanism of action of yaku'amide B, a structurally complex peptidic natural product derived from deep-sea sponge found in the waters near Yakushima Island, ...
Phys.org / Pi Day: From rockets to cancer research, here's how the number pi is embedded in our lives
Math nerds and dessert enthusiasts unite to celebrate Pi Day every March 14, the date that represents the first three digits of the mathematical constant pi.
Phys.org / Bacteria that generate electricity: How a shellfish-based gel could monitor wastewater and food
Microbial bioelectronic sensors use living bacteria that can create an electrical signal in response to the presence of a target substance, or analyte. These types of sensors offer many advantages over other types of biosensors ...
Phys.org / New Panama tree species identified after 25 years is already endangered
In 2000, a group of STRI botanists collected samples of all the plants from the genus Clusia they could find in Panama to find out how the different species in this group are related.
Phys.org / Not one ring but many: Antioxidant enzyme family can assemble in far more diverse ways than previously thought
Peroxiredoxins are among the most abundant enzymes involved in managing oxidative stress. They control the levels of peroxides such as hydrogen peroxide, relay redox signals, and help protect other proteins during stress. ...
