How adult penguins fish and the body condition of their chicks are directly linked to local fish abundance, and could potentially inform fishery management, a new study has found.
The researchers studied an endangered African penguin colony during a rare three-year closure of commercial fisheries around Robben Island, South Africa, and their findings are published today in the Journal of Applied Ecology.
Women who breastfed their babies are less likely to develop heart disease later in life, according to findings to be presented in Lyon, at the European Society of Endocrinology annual meeting, ECE 2019. The study also suggests that the protective effect on heart health is increased in women who breastfed for longer periods of time. These findings provide further evidence for the long-term health benefits of breastfeeding and that women should be encouraged to do so when possible.
UPTON, NY--From the ancient pyramids to modern buildings, various three-dimensional (3-D) structures have been formed by packing shaped objects together. At the macroscale, the shape of objects is fixed and thus dictates how they can be arranged. For example, bricks attached by mortar retain their elongated rectangular shape. But at the nanoscale, the shape of objects can be modified to some extent when they are coated with organic molecules, such as polymers, surfactants (surface-active agents), and DNA.
Conservation decisions based on population counts may fail to protect large, slow-breeding animals from irrevocable decline, according to new research coinciding with Endangered Species Day.
Changes to alpine streams fed by glaciers and snowfields due to a warming climate threaten to dramatically alter the types of bacteria and other microbes in those streams, according to a research team that included a University of Wyoming scientist.
But streams that are fed by underground ice insulated by rock -- called "icy seeps" -- offer some hope that the impact of climate change will be less severe in some areas, say the researchers, who include Lusha Tronstad, research scientist with UW's Wyoming Natural Diversity Database (WYNDD).
ITHACA, N.Y. - Far below Bermuda's pink sand beaches and turquoise tides, geoscientists have discovered the first direct evidence that material from deep within Earth's mantle transition zone - a layer rich in water, crystals and melted rock - can percolate to the surface to form volcanoes.
TALLAHASSEE, Fla. -- When it comes to choosing a mate, female guppies often go for the mates with the flashiest, most interesting color patterns.
But why is that? Turns out, it's all about psychology.
In a new study, Florida State University researchers found that these tiny, tropical fish often choose a mate that physically stands out from the rest of the pack because of a common type of learning called habituation. Through habituation, animals -- in this case guppies -- stop responding to a stimulus after prolonged exposure.
An innovative use of instruments that measure the ocean near Antarctica has helped Australian scientists to get a clearer picture of how the ocean is melting the Antarctic ice sheet.
Until now, most measurements in Antarctica were made during summer, leaving winter conditions, when the sea freezes over with ice, largely unknown.
Scientists have discovered a new material that could hold the key to unlocking the potential of hydrogen powered vehicles.
As the world looks towards a gradual move away from fossil fuel powered cars and trucks, greener alternative technologies are being explored, such as electric battery powered vehicles.
Another 'green' technology with great potential is hydrogen power. However, a major obstacle has been the size, complexity, and expense of the fuel systems - until now.
WASHINGTON, D.C. May 13, 2019 -- Children's brains are sponges. These voracious little learners glean all kinds of information from the people around them. In particular, children mimic and learn speech patterns from their family. Previous work has shown that infants attend selectively to their mother's voice over another female's voice. But new research suggests that children learn new words best from other children.

New research in The Journal of Physiology has found, using a mouse model, that microbes in the maternal intestine may contribute to impairment of the gut barrier during pregnancy.
Collaborating scientists at the U.S. Department of Energy's Ames Laboratory, Brookhaven National Laboratory, and Princeton University have discovered a new layered ferromagnetic semiconductor, a rare type of material that holds great promise for next-generation electronic technologies.
NASA's Aqua satellite used infrared light to analyze the strength of storms in Tropical Cyclone Lili as it moved through the Southern Indian Ocean. Infrared data provides temperature information, and the strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.
