Fifty years of data show new changes in bird migration

A growing body of research shows that birds' spring migration has been getting earlier and earlier in recent decades. New research on Black-throated Blue Warblers, a common songbird that migrates from Canada and the eastern US to Central America and back every year, uses fifty years of bird-banding data to add another piece to the puzzle, showing that little-studied fall migration patterns have been shifting over time as well.

A better pregnancy test for whales

To determine whale pregnancy, researchers have relied on visual cues or hormone tests of blubber collected via darts, but the results were often inconclusive. Research points to a weakness of previous testing and evaluation methods and provides a new hormone

The Earth formed much faster than previously thought

By measuring iron isotopes, researchers have shown that our planet originally formed much faster than previously thought. This finding provides new insights on both planetary formation and the likelihood of water and life elsewhere in the universe.

Huge stores of Arctic sea ice likely contributed to past climate cooling

Climate scientists propose that massive amounts of melting sea ice in the Arctic drained into the North Atlantic and disrupted climate-steering currents, thus playing an important role in causing past abrupt climate change after the last Ice Age, from about 8

Climate scientists propose that massive amounts of melting sea ice in the Arctic drained into the North Atlantic and disrupted climate-steering currents, thus playing an important role in causing past abrupt climate change after the last Ice Age, from about 8,000 to 13,000 years ago.

Beyond the brim, Sombrero Galaxy's halo suggests turbulent past

These latest Hubble observations of the Sombrero galaxy indicate only a tiny fraction of older, metal-poor stars in the halo, plus an unexpected abundance of metal-rich stars. Past major galaxy mergers are a possible explanation, though the stately Sombrero shows none of the messy evidence of a recent merger of massive galaxies.

Earthquakes disrupt sperm whales' ability to find food

Scientists studying sperm whales have discovered earthquakes affect their ability to find food for at least a year. The research is among the first to examine the impact of a large earthquake on a population of marine mammals, and offers new insight into how top predators such as sperm whales react and adapt to a large-scale natural disturbance.

Risk of coronavirus importation in Africa

Egypt, Algeria and Republic of South Africa are the African countries most at risk for coronavirus COVID-19 importation in the continent, due to high air traffic with the contaminated Chinese provinces. But these countries are also among the best equipped on the continent to quickly detect and deal with new cases. In other African countries, the risk of importation is lower, but health organization deficiencies raise concerns about rapid spread.

Journey to the center of Mars

While InSight's seismometer has been patiently waiting for the next big marsquake to illuminate its interior and define its crust-mantle-core structure, two scientists, have built a new compositional model for Mars. They used rocks from Mars and measurements from orbiting satellites to predict the depth to its core-mantle boundary, some 1,800 km beneath the surface and have been able to suggest that its core contains moderate amounts of sulfur, oxygen and hydrogen as light elements.

In ancient Greek mythology, Icarus' wax wings melted when he dared to fly too close to the sun. Now, researchers have made artificial wings that are actually powered by the sun. The tiny wings, which can flap even faster than those of butterflies, could someday be used in robots or devices for solar energy harvesting, the researchers say.

A new way to assess male fertility

Current tests for male fertility include measuring the concentration and motility of spermatozoa. However, other characteristics of sperm, such as their ability to follow a chemical trail to the egg, can influence the likelihood of fertilization. Now, researchers have devised a quick and convenient microfluidic chip to assess this chemotactic response of spermatozoa, which could help provide a more complete picture of a man's fertility.
