Scanning the first images of a well-known early galaxy taken by NASA’s James Webb Space Telescope (JWST), Cornell astronomers were intrigued to see a blob of light near its outer edge.
Symbiotic relationships between legumes and the bacteria that grow in their roots are critical for plant survival. Without those bacteria, the plants would have no source of nitrogen, an element that ...
For the first time, researchers have mapped the biological diversity in marine sediment, one of Earth's largest global biomes. Although marine sediment covers 70% of Earth's surface, little was known ...
A new U.S. National Science Foundation-supported study provides some of the most comprehensive evidence to date of the lengths penguins will go for a meal. The results were reported in the journa...
We report detailed lithological and chemical characteristics of deep-sea sediments, including rare-earth elements and yttrium-rich mud (REY-rich mud), in the Japanese Exclusive Economic Zone (EEZ) ar...
The last liquids of the lunar magma ocean, known as urKREEP, should be highly enriched in volatiles, such as water, fluorine, and chlorine. We find chlorine-rich glasses in two pristine KREEP basalts...
Seven piston cores were collected from the seafloor ~250 km south of Minamitorishima Island in the western North Pacific Ocean during the cruise KR13-02 of R/V Kairei; in some portions of cores PC04 ...
Sub-bottom profiling was conducted in the Japanese Exclusive Economic Zone (EEZ) around Minamitorishima Island, western Pacific Ocean, to investigate the features and distribution of mud rich in rare...
Based on characteristics of the distribution pattern of the western Eger Rift spring gases, a distribution pattern is presented for the gases of the French Massif Central. The central parts of these ...
The field of control provides the principles and methods used to design physical and information systems that maintain desirable performance by sensing and automatically adapting to changes in the env...

Activity time budget patterns and grazing response to sward and environmental conditions were investigated for paddocks of sheep and goats co-grazing for conservation purposes on a semi-natural specie...
We report new K-band, radio continuum, and CO (1-0) imaging observations and 850 μm photometric observations of PDS 456, the most luminous QSO in the local universe (z < 0.3). The 06 resolution K-band...
A team of scientists, led by the University of Toronto’s Barbara Sherwood Lollar, has mapped the location of hydrogen-rich waters found trapped kilometres beneath Earth’s surface in rock fracture...
Protein aggregation has been implicated in several catastrophic diseases (neurodegeneration, diabetes, ALS) and its complexity has also become a major obstacle in large-scale production of protein-bas...
