A new study from the University of Helsinki using miniaturized satellite-based tags revealed that during drier periods desert bats must fly further and longer to fulfil their nightly needs. According to researchers this signals their struggle in facing dry periods.
Scientists evaluated multiple satellite and reanalysis precipitable water vapor (PWV) datasets against radiosonde observations in Central Asia. They further constructed a skill-weighted ensemble mean of the reanalysis datasets, based on the different performances of individual datasets.
A group of researchers led by Skoltech Professor Pavel Troshin studied coordination polymers, a class of compounds with scarcely explored applications in metal-ion batteries, and demonstrated their possible future use in energy storage devices with a high charging/discharging rate and stability. The results of their study were published in the journal Chemistry of Materials.
An analysis of helium isotopes locked inside 'super-deep' diamonds hundreds of kilometers below Earth's surface suggests that vast reservoirs of molten primordial source rock, perhaps nearly as old as the Earth, are present.
Analyses show that gases found in microscopic inclusions in diamonds come from a stable subterranean reservoir at least as old as the Moon, hidden more than 410 km below sea level in the Earth's mantle.
Freshwater wetlands from Georgia to New York are home to a previously unrecognized species of medicinal leech, according to scientists at the Smithsonian's National Museum of National History. The new species was first identified from specimens collected in southern Maryland less than 50 miles from Washington, D.C., prompting a search through marshes and museum collections that revealed that the leech has long occupied a range that stretches throughout the eastern United States.
