Astronomers uncover the engine behind the most powerful stellar flares in the Kepler field‎

A new study led by researchers at the Konkoly Observatory of the HUN-REN Research Centre for Astronomy and Earth Sciences (HUN-REN CSFK) in Budapest has revealed what makes a distant red giant star the most explosively active in the entire Kepler field—and the answer lies in a surprisingly subtle interplay between a close stellar companion, vast dark starspots and a highly efficient internal magnetic dynamo.

Australia urged to put biodiversity at the heart of planning as global targets slip out of reach‎

The world is falling short of its biodiversity commitments because nature is still treated as an afterthought in decisions about housing, infrastructure, agriculture, energy, mining and conservation, according to a new UNSW report.

The ocean's most abundant 'loner' microbe has a sticky second life‎

The oxygen in about every other breath we take comes from microscopic cells—phytoplankton—drifting in the surface of the ocean. Among them is Prochlorococcus, the smallest and most abundant photosynthetic organism in the seas. It single-handedly accounts for roughly 10% of all the carbon that the land and the oceans pull from the atmosphere each year.

Tackling Lake Erie's algal blooms requires targeted conservation strategies‎

Anyone living along the coast of Lake Erie will be well aware of the periodic algal blooms that appear on its surface. The greenish blooms can cause rashes and other health problems and pose risks to both humans and animals.

Genomes of 20 eastern Finnish species provide unique insights into species' adaptations to local conditions‎

In recent years, researchers at the University of Eastern Finland have been both leading and contributing to collaborative genome projects. These efforts have produced reference-quality genome assemblies for the Finnish brown hare and the mountain hare, as well as the Saimaa ringed seal, in collaboration with research partners.

Atomic memory keeps distant ions entangled for about 10 seconds‎

Quantum networks, systems that connect devices and allow them to exchange information encoded in the quantum states of particles, could enable more secure communications. To build these networks, physicists need to devise strategies that allow distant particles to share quantum states, preserving them long enough to perform calculations or enable communication between devices.

Smart planning of outdoor sports tournaments using environmental heat measurements‎

Rising temperatures caused by climate change are making it harder to organize outdoor sports events safely. Exercising in the heat lowers performance and raises the risk of heatstroke, which is a leading cause of nontraumatic death among professional athletes.

Can surplus-food apps have too much competition?‎

Apps that let businesses sell surplus food at a discount in "surplus bags" have become a popular way to keep edible food out of landfills while giving consumers access to lower-cost meals and groceries.
