A Newcastle University study has shown that baby birds that have a difficult start in life grow to be fatter and greedier than their more fortunate siblings.
The researchers, led by Professor Melissa Bateson and Dr Clare Andrews, discovered that stress and difficulties as a chick made a long lasting impression on a starling's relationship with food.
Less than 20 years ago the world learned that the universe is expanding ever faster, propelled by dark energy. The discovery was made possible by Type Ia supernovae; extraordinarily bright and remarkably similar in brightness, they serve as "standard candles" essential for probing the universe's history.
Mars has been all over the news, from the blockbuster finding of seasonal water on the Red Planet to the wildly successful film, The Martian. Now, researchers--including those at the University of Iowa--have learned more about what happened to the climate on Mars since it was a warm and watery planet billions of years ago.
Using NASA's Hubble Space Telescope to conduct a "cosmic archaeological dig" at the very heart of our Milky Way galaxy, astronomers have uncovered the blueprints of our galaxy's early construction phase.
Peering deep into the Milky Way's crowded central hub of stars, Hubble researchers have uncovered for the first time a population of ancient white dwarfs -- smoldering remnants of once-vibrant stars that inhabited the core. Finding these relics at last can yield clues to how our galaxy was built, long before Earth and our sun formed.
This issue of Science features four studies highlighting results from the Mars Atmosphere and Volatile Evolution (MAVEN) mission, designed to study Mars' upper atmosphere, ionosphere, and magnetosphere. The novel data reveals some surprises, as well as some adjustments to previous theories and estimates. This issue's cover represents a real data visualization of Mars' magnetic field being bombarded by a powerful solar ejection, resulting in a stunning visual of fire-like tendrils emulating from the Red Planet.
When Sarah Thébaud analyzed survey data from 24 countries -- including the United States -- between 2001 and 2008, she found some interesting evidence regarding gender gaps and entrepreneurship and the relationship between those gender gaps and government policies.
It turns out, the assistant professor of sociology at UC Santa Barbara discovered, the circumstances that spur women to start their own businesses in the first place have a tremendous influence on the kinds of enterprises they establish.
NASA's Global Precipitation Measurement mission or GPM core satellite caught another tropical cyclone forming on Nov. 4, 2015 at 1255 UTC (7:55 a.m. EST) in the Arabian Sea.
In 1920's Edwin Hubble, an American astronomer, showed that the recessional velocity of a galaxy increases with its distance from the earth, known as Hubble's law. Hubble's law is taken as the first observational basis for the expansion of the Universe, and provides strong evidence for the Big Bang model. The value of the expansion rate is called the Hubble constant. Hubble constant is a critical parameter in cosmology and the measurement of Hubble constant is a key task for the astrophysicists and cosmologists. Recently a Chinese team leaded by Prof.
SAN ANTONIO, TX (November 5, 2015) - Imagine you suffer from severe asthma, and you've tried every treatment available, but nothing has worked. You still can't breathe. Then a new therapy comes along that attacks the source of the asthma, as opposed to the symptoms, and treats the disease at a cellular level. That's the promise of biologics, and the topic of four presentations at the 2015 ACAAI Annual Scientific Meeting in San Antonio, November 5-9.
MINNEAPOLIS - An estrogen-like drug, raloxifene, has no demonstrated benefit on memory and thinking skills for women with dementia due to Alzheimer's disease, according to a study published in the November 4, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology.
RIVERSIDE, Calif. (http://www.ucr.edu) -- Researchers at the University of California, Riverside have found parts produced by some commercial 3D printers are toxic to certain fish embryos. Their results have raised questions about how to dispose of parts and waste materials from 3D printers.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered an adolescent protostar that is undergoing a rapid-fire succession of growth spurts. Evidence for this fitful youth is seen in a pair of intermittent jets streaming away from the star's poles.
New Haven, Conn. - A Yale-led study has found a cluster of young stars that develop in distinct, episodic spurts.
It is the first time astronomers have seen such a growth pattern within a star cluster -- a chaotic, turbulent environment that is common for star formation. Previous observations have focused on stars forming in more isolated regions of space.
WASHINGTON, DC -- Annual snow accumulation on West Antarctica's coastal ice sheet increased dramatically during the 20th century, according to a new study published in the American Geophysical Union journal Geophysical Research Letters.
The research gives scientists new insight into Antarctica's blanket of ice. Understanding how the ice sheet grows and shrinks over time enhances scientists' understanding of the processes that impact global sea levels, according to the study's authors.
The Global Precipitation Measurement mission or GPM core satellite added up the totals as Cyclone Chapala dropped a lot of rain moving across the Arabian Sea to landfall in Yemen.
