An afternoon rainstorm might seem like an inconvenience at times, but rainfall is an essential part of the world ecosystem. Most of us know this.

ALMA Captures Dramatic Stellar Fireworks
1350 light years away, in the constellation of Orion (the Hunter), lies a dense and active star formation factory called the Orion Molecular Cloud 1 (OMC-1), part of the same complex as the famous Orion Nebula. Stars are born when a cloud of gas hundreds of times more massive than our Sun begins to collapse under its own gravity. In the densest regions, protostars ignite and begin to drift about randomly. Over time, some stars begin to fall toward a common centre of gravity, which is usually dominated by a particularly large protostar — and if the stars have a close encounter before they can escape their stellar nursery, violent interactions can occur.
Scientists uncover isotopic fingerprint of N2O emissions from Arctic tundra
A new study from the University of Eastern Finland presents, for the first time, the isotopic fingerprint of nitrous oxide produced by Arctic soils. The finding opens new avenues for predicting future trends in atmospheric nitrous oxide as well as in identifying climate change mitigation actions in the Arctic, a region that is particularly sensitive to climate change.
Satellites map carbon sequestered by forests, with accuracy of up to ten metres
Led by VTT, the EU North State project has developed a new method of using satellite images to evaluate the forest carbon balance. The carbon balance indicates how much carbon is sequestered or released by forests each year. This enables the carbon balance to be displayed on digital maps, with an accuracy of up to ten metres.
New Map Shows How Groundwater Pumping Could Affect the Malad River
A new report illustrates how groundwater pumping can affect the amount of water available in streams within the Malad-Lower Bear River Area in Utah. The product was developed by the U.S. Geological Survey, in cooperation with the Utah Department of Natural Resources, Division of Water Rights.
Puffins that stay close to their partner during migration have more chicks
Many long-lived birds, such as swans, albatrosses or indeed, puffins, are known for their long-lived, monogamous, ‘soulmate’ pairings. Scientists have long understood that in these species, reproductive performance is influenced by pair bond strength and longevity, with long-established pairs usually better at rearing offspring. However, in species like puffins which have to migrate to distant wintering grounds during the non-breeding season, very little is known about how mates maintain their pair-bond and behave. Do they keep in contact to maintain their relationship? Or do they go their own way and abandon their mate until the following spring?
