Old star offers sneak preview of the future
Estrogen or progesterone makes a difference in sexual desire
Northwestern Medicine scientists have discovered for the first time that the rhythm of breathing creates electrical activity in the human brain that enhances emotional judgments and memory recall. These effects on behavior depend critically on whether you inhale or exhale and whether you breathe through the nose or mouth.
Scientists closely tracking the survival of endangered Sacramento River salmon faced a puzzle: the same high temperatures that salmon eggs survived in the laboratory appeared to kill many of the eggs in the river
Pitt chemical engineering team identifies new catalyst that advances capture and conversion of atmospheric carbon dioxide
Scientists have called superoxide out as the main culprit behind coral bleaching: The idea is that as this toxin build up inside coral cells, the corals fight back by ejecting the tiny energy- and color-producing algae living inside them. In doing so, they lose their vibrancy, turn a sickly white, and are left weak, damaged, and vulnerable to disease.
New research opens up the deep history of the Greenland Ice Sheet, looking back millions of years farther than previous techniques allowed—and raises urgent questions about if the giant ice sheet might dramatically accelerate its melt-off in the near future.
The study focused on the skeletal changes that occurred during growth in the small carnivorous dinosaur Coelophysis (SEE-lo-FY-sis), one of the earliest dinosaurs.
An analysis of 2,000-year-old human remains from several regions across the Italian peninsula has confirmed the presence of malaria during the Roman Empire, addressing a longstanding debate about its pervasiveness in this ancient civilization.
A researcher at Missouri University of Science and Technology wants to scrap the traditional electronic and paper survey approaches to gathering marketing and information systems data in favor of scanning your brainwaves.
The “reproducibility crisis” in biomedical research has led to questions about the scientific rigor in animal research, and thus the ethical justification of animal experiments. In research publishing in the Open Access journals PLOS Biology and PLOS ONE on December 2nd, 2016, researchers from the University of Bern have assessed scientific rigor in animal experimentation in Switzerland. The study, commissioned by the Swiss Federal Food Safety and Veterinary Office (FSVO), found widespread deficiencies in the reporting of experimental methodology.
Advertisers often use humor to grab customers' attention, but they should do so with caution, according to a recently published study in the Journal of Marketing Behavior.
Creative achievement can provide a buffer against being anxious about death, research from psychologists at the University of Kent shows.
In a new study, Columbia Engineering researchers looked at increasing trends in the severity of tornado outbreaks where they measured severity by the number of tornadoes per outbreak. They found that these trends are increasing fastest for the most extreme outbreaks.
Johns Hopkins investigators report that their analysis of a national database representing more than 1 billion emergency department visits shows that over a recent eight-year period, nothing much has changed in the rates of unsuccessful suicide attempts, or in the age, gender, seasonal timing or means used by those who tried to take their lives in the United States.
In a small double-blind study, Johns Hopkins researchers report that a substantial majority of people suffering cancer-related anxiety or depression found considerable relief for up to six months from a single large dose of psilocybin -- the active compound in hallucinogenic "magic mushrooms."
Researchers at Stockholm University and Brooklyn College have combined knowledge from the fields of artificial intelligence, ethology and the psychology of learning to solve several problems concerning the behaviour and intelligence of animals.
Australopithecus afarensis arm bones were strong relative to leg bones; walking gait was likely inefficient
NIBIB-funded researchers have used fast fMR Ito image rapidly fluctuating brain activity during human thought. fMRI measures changes in blood oxygenation, which were previously thought to be too slow to detect the subtle neuronal activity associated with higher order brain functions. The new discovery is a significant step towards realizing a central goal of neuroscience research: mapping the brain networks responsible for human cognitive functions such as perception, attention, and awareness.
48 skeletons discovered in ‘Plague Pit’ – 27 of them children; Extremely rare discovery suggests community was overwhelmed by the Black Death
Whether Peter Paul Rubens or Damien Hirst – the personal taste of art can be argued. Scientists from the Faculty of Psychology of the University of Vienna have now shown that the individual taste of art is also dependent on social factors. The personal valuation of art was influenced by who else liked the work - or not. And even the value of a painting strengthened the subjective feeling of how much a work of art appeals to us. The study was recently published in the international journal "Psychology of Aesthetics, Creativity and the Arts".
Why do some animals have extravagant, showy ornaments -- think deer antlers, peacock feathers and horns on beetles -- that can be a liability to survival? Northwestern University researchers have a possible explanation for this puzzling phenomenon of evolution.
New research from ASU suggests parents shouldn't obsess over grades and extracurricular activities for young schoolchildren, especially if such ambitions come at the expense of social skills and kindness.

Sleep deprivation affects children's brains differently than adults', according to a new study
In a remote area of north-central Tanzania, men leave their huts on foot, armed with bows and poison-tipped arrows, to hunt for their next meal. Dinner could come in the form of a small bird, a towering giraffe or something in between. Meanwhile, women gather tubers, berries and other fruits.
A defect in a gene that produces dopamine in the brain appears to accelerate the onset of Parkinson’s disease, according to new research from Iowa State University. The effect is particularly dramatic for young-to-middle-age adults.
A laboratory study of four animal species and their microbiota finds that each species hosts a unique community of microbes that can significantly improve its health and fitness.
A Northwestern University research team has developed a first-of-its-kind soft, flexible microfluidic device that easily adheres to the skin and measures the wearer’s sweat to show how his or her body is responding to exercise. A little larger than a quarter and about the same thickness, the simple, low-cost device analyzes key biomarkers to help a person decide quickly if any adjustments, such as drinking more water or replenishing electrolytes, need to be made or if something is medically awry.
The Northeastern coast of the USA could be struck by more frequent and more powerful hurricanes in the future due to shifting weather patterns, according to new research.
After decades of progress, earnings gap between black and white men is back at 1950 levels.
Lack of paid leave and outdated maternity care are barriers to breastfeeding that disproportionately impact families of color. This is the first study to show how these disparities translate into differences in health outcomes.
Sleepiness after a large meal is something we all experience, and new research with fruit flies suggests higher protein and salt content in our food, as well as the volume consumed, can lead to longer naps.
People living with serious illness who receive palliative care have better quality of life.
Humans, as well as many other organisms, possess internal clocks. The exact timing, however, can differ between individuals – for instance, some people are early risers whereas others are "night owls". Neurobiologist Kristin Tessmar-Raible and her team at the Max F. Perutz Laboratories (MFPL) of the University of Vienna and Medical University of Vienna investigated that underlie such timing variations or "chronotypes". The non-biting midge Clunio marinus has two internal clocks, since it times its reproduction according to sun and moon. The team around Tessmar-Raible and Postdoc Tobias Kaiser were now able to identify relevant genes for this adaptation, and published their results in the current issue of "Nature".
Studying how gut bacteria affect behavior in zebrafish could lead to a better understanding of how probiotics may affect the central nervous system in humans.
