The evolution of male songbirds as the colorful consorts of drab female partners is more complicated than long thought, says a McMaster researcher on a team that looked at nearly 6,000 species for a massive study published in the journal Nature.
UC San Diego paper finds young adults are more envious than older adults. They are more envious over looks and for a wider range of other reasons, too. It also appears that both men and women are more likely to envy someone who is of their own gender and approximately their own age
Used alone, a cell phone app that tracks exercise, calories and weight loss goals is, on average, not enough to create meaningful weight loss in young adults, according to new research from Duke Medicine.
The highest-resolution radar images of asteroid 2015 TB145's safe flyby of Earth have been processed and yield new information about its surface features.
Diamonds may not be as rare as once believed, but this finding in a new Johns Hopkins University research report won’t mean deep discounts at local jewelry stores.
New research shows that brain responses to written food words differ between lean individuals and those with obesity, and suggests that both stress and genetics could influence excess eating. The pair of studies led by Susan Carnell, PhD, member of The Obesity Society (TOS) and Assistant Professor of Psychiatry and Behavioral Sciences at Johns Hopkins University School of Medicine, reinforces the need to better understand how the external food environment interacts with our biology, and may aid the development of behavioral interventions to help individuals with obesity or those at high risk for the disease. The findings will be unveiled during an oral presentation on Tuesday, Nov. 3, and a poster presentation on Wednesday, Nov. 4, at The Obesity Society Annual Meeting at ObesityWeekSM 2015 in Los Angeles, CA.
Preschoolers who score lower on a working memory task are likely to score higher on a dropout risk scale at the age of 13, researchers at Université Sainte-Anne and the University of Montreal revealed today.
The recently commissioned MicroBooNE experiment at Fermi National Accelerator Laboratory has reached a major milestone: It detected its first neutrinos on Oct. 15, marking the beginning of detailed studies of these fundamental particles whose properties could be linked to dark matter, matter’s dominance over antimatter in the universe and the evolution of the entire cosmos since the Big Bang.
Twenty-five boxes of Velvet Underground material were recently donated to the library’s Division of Rare and Manuscript Collections at Cornell University by collector and author Johan Kugelberg.
A study in the Nov. 2 issue of Proceedings of the National Academy of Sciences is the first to fully document the demographic impacts of West Nile virus on North American bird populations. Data from bird-banding stations shows more species were hit than suspected, and half of those have yet to recover.
In their soon-to-be-published study, two Texas Tech University researchers said some of the venomous contents in the bats’ saliva likely evolved by recruiting ancestral genes to produce new transcript molecules rather than by creating completely new gene sequences.
What people believe they want and what they prefer are not always the same thing. When outperformed as an element of romantic attraction, the difference between affinity and desirability becomes clearer as the distance between people gets smaller.
For centuries, cod were the backbone of New England’s fisheries and a key species in the Gulf of Maine ecosystem. Today, cod stocks are on the verge of collapse, hovering at 3-4% of sustainable levels. Even cuts to the fishery have failed to slow this rapid decline, surprising both fishermen and fisheries managers.
A team of astronomers is proposing that huge spiral patterns seen around some newborn stars, merely a few million years old, may be evidence for the presence of giant, unseen planets.
In the recent sci-fi hit, The Martian, the main character, astronaut Mark Watney (played by Matt Damon), manages to grow potatoes on the planet with a mix of ingenuity, science, and a bit of Hollywood make-believe. Could it work?
Researchers are sifting through an avalanche of data produced by one of the largest cosmological simulations ever performed, led by scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory. The simulation, run on the Titan supercomputer at DOE's Oak Ridge National Laboratory, modeled the evolution of the universe from just 50 million years after the Big Bang to the present day—from its earliest infancy to its current adulthood. Over the course of 13.8 billion years, the matter in the universe clumped together to form galaxies, stars and planets; but we’re not sure precisely how.
If you don’t have health insurance, or your insurance coverage still leaves you with big bills, hospitals are supposed to let you know if you qualify for free or reduced-price care, and to charge you fairly even if you don’t. (That is, if they want to keep their tax-free nonprofit status.) But a new study finds many nonprofit hospitals have room to improve.
Chemical changes in brain cells caused by disturbances in the body’s day-night cycle may be a key underlying cause of the learning and memory loss associated with Alzheimer’s disease, according to a University of California, Irvine study.
