In mice, microglia may persist the entire lifespan of the animal. The cells’ lifetime may be linked to their role in immune memory and neurodegenerative diseases.
Researchers have developed a simple, low-cost, and environmentally sound method for fabricating a highly-efficient selective solar absorber (SSA) to convert sunlight into heat for energy-related applications. The team used a ‘dip and dry’ approach whereby strips coated with a reactive metal are dipped into a solution containing ions of a […]
Retrotransposons are repetitive elements that form almost half of the mammalian genome. Even though they are so common, they have previously been considered to be fairly insignificant. Scientists have now shown in that retrotransposons play an important role in embryonic development.
A chance combination of a gravitational lens and polarized waves coming from a distant quasar gave astronomers the tool needed to make a measurement important to understanding the origin of magnetic fields in galaxies.
The biggest fossil ever found of a dinosaur-era marine reptile called the Ichthyosaurus was pregnant when it died. Researchers say they found an embryo inside the skeleton that includes pieces of vertebrae, ribs, a forefin and a shoulder blade, according to a study in the journal Acta Palaeontologica Polonica. Although […]
Metal oxides are promising candidates for cheap and stable photoelectrodes for solar water splitting, producing hydrogen with sunlight. Unfortunately, metal oxides are not highly efficient in this job. A known remedy is a treatment with heat and hydrogen. Scientists have now discovered why this treatment works so well, paving the […]
WASHINGTON — Seeking to restore capacity for customers impacted by a satellite malfunction earlier this year, fleet operator SES is swapping launches between SpaceX and Arianespace, the company announced today. Hawthorne, California-based SpaceX, previously contracted to launch SES-14, will instead launch SES-12. Arianespace of Evry, France, will launch SES-14 on […]
