Thousands of remarkable fossil birds from the time of the dinosaurs have been uncovered in China. However, most of these fossils are flattened in the rock, even though they commonly preserve fossils.
New research by Sarah Horton, an anthropologist at the University of Colorado Denver, reveals that employers in agricultural industries often take advantage of migrants' inability to work legally by making their employment contingent upon working under the false or borrowed identity documents provided by employers.
Rising sea temperatures in the Mediterranean are encouraging alien lionfish species to invade and colonise new territories with potentially serious ecological and socioeconomic impacts.
The book addresses how sales can help organisations to become more customer oriented and considers how they are responding to challenges such as increasing competition, more demanding customers and a more complex selling environment.
DNA tests have confirmed that one of the three southern rockhopper penguin chicks born at Osaka Aquarium Kaiyukan between June 4 and 6 was conceived through artificial insemination. This is the result of a project led by Kaiyukan with the collaboration of Associate Professor KUSUNOKI Hiroshi (Kobe University Graduate School of Agricultural Science). It is the world's first successful case of a southern rockhopper penguin being conceived through artificial insemination.
New research from the University of British Columbia shows a higher risk of mortality during extreme heat events in neighbourhoods that tend to get hotter and where people tend to be poorer.
Circadian rhythms are internal clocks that determine many of an organism's daily rhythms, for example sleep-wake, feeding, urinary output and hormone production. Aligned with the environment by external forces such as sunlight and ambient temperature, circadian rhythms are important for animal health and survival. Disturbances of the circadian clock are associated with a variety of diseases in humans and animals, including cancer, mental illnesses and metabolic disorders, such as diabetes and obesity.
University of Wisconsin–Madison researchers studying monkeys have shown that one infection with Zika virus protects against future infection, though pregnancy may drastically prolong the time the virus stays in the body.
A new study led by scientists at SBP describes a technology that could lead to new therapeutics for traumatic brain injuries. The discovery provides a means of homing drugs or nanoparticles to injured areas of the brain.
Numerical models show hot, rocky exoplanets can change their chemistry by vaporizing rock-forming elements in steam atmospheres that are then partially lost to space.
Movie sets are normally the home of three-dimensional motion caption systems, but researchers used the same video recording system in a lab to measure the way pregnant women walk. This is the first research study to use 3D motion capture to create a biomechanical model of pregnant women. The results verify the existence of the "pregnancy waddle" and should enable future studies on how to make everyday tasks safer and more comfortable for pregnant women.
Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone realized.
Scientists and doctors in recent decades have made vast leaps in the treatment of cardiac problems - particularly with the development in recent years of so-called "cardiac patches," swaths of engineered heart tissue that can replace heart muscle damaged during a heart attack.
Oxford, June 27, 2016 - Sending text messages on a smartphone can change the rhythm of brain waves, according to a new study published in Epilepsy & Behavior.
Teacher burnout and student stress may be linked, according to a University of British Columbia study.
Stunning new images and the highest-resolution maps to date of Jupiter at thermal infrared wavelengths give a glowing view of Juno's target, a week ahead of the NASA mission's arrival at the giant planet. The maps reveal the present-day temperatures, composition and cloud coverage within Jupiter's dynamic atmosphere, and show how giant storms, vortices and wave patterns shape the appearance of the giant planet. The observations will be presented on Monday 27 June at the National Astronomy Meeting in Nottingham by Dr Leigh Fletcher of the University of Leicester.
High workload, rigid rules, and conflicting pressures from their employers are all leading to community pharmacy staff deviating from standard procedures at times to ensure patients receive the tailored care they require, a new study from The University of Manchester has found.
Scientists led by Durham University's Institute for Computational Cosmology ran the huge cosmological simulations that can be used to predict the rate at which gravitational waves caused by collisions between the monster black holes might be detected.
A team of investigators from Brigham and Women's Hospital and the University of Massachusetts have developed a suite of computer algorithms that can accurately predict the behavior of the microbiome - the vast collection of microbes living on and inside the human body. In a paper published in Genome Biology, the authors show how their algorithms can be applied to develop new treatments for serious diarrheal infections, including Clostridium difficile, and inflammatory bowel disease. The team also shows how to identify bacteria most crucial for a healthy and stable microbial community, which could inform the development of probiotics and other therapies.
Wide-ranging species may have different levels of bacterial immunity than their rarer relatives, new research suggests.
A global consortium of researchers banded together to conduct an epidemiological study analyzing specific omega-3 fatty acid biomarkers and heart disease. They found that blood levels of omega-3 fatty acids from seafood and plant-based foods are associated with a lower risk of fatal heart attack.
Coffee is enjoyed by millions of people every day and the ‘coffee experience’ has become a staple of our modern life and culture. While the current body of research related to the effects of coffee consumption on human health has been contradictory, a study in the June issue of Comprehensive Reviews in Food Science and Food Safety, which is published by the Institute of Food Technologists (IFT), found that the potential benefits of moderate coffee drinking outweigh the risks in adult consumers for the majority of major health outcomes considered.
Even if you have what you might think of as good health insurance, your next hospital stay could cost you more than $1,000 out of your own pocket. And that amount has gone up sharply in recent years – a rise of more than 37 percent just for straightforward hospital stays for common conditions.
UAlberta scientists study compounds with anti-prion properties to address rare but fatal diseases.
Monumental Roman Gate Discovered at Sussita National Park, Following Discovery of Unique Mask of the God Pan. Expedition head Dr. Michael Eisenberg of the University of Haifa: “Now that the whole gate has been exposed, we not only have better information for dating the mask, but also a clue to its function. Are we looking at a gate that led to the sacred compound of the god Pan?”
A new study of the 37,000-year old remains of the “Deep Skull” – the oldest modern human discovered in island South-East Asia – has revealed this ancient person was not related to Indigenous Australians, as had been originally thought.
Before your family heads to Mexico, Asia or beyond, do a little planning ahead of time to keep everyone healthy during their journey. Dr. Nava Yeganeh, an assistant professor of pediatric infectious diseases and director of the Pediatric International Travel and Adoption Clinic at Mattel Children’s Hospital UCLA, explains three important strategies.
A psychology study by the University of Stirling has found that men think women with make-up on are more ‘prestigious’, while women think women who wear make-up are more ‘dominant’.
Sparrows form pair bonds that are normally monogamous, but many females are unfaithful to their partner and have offspring with other males.
Two massive blob-like structures lie deep within the Earth, roughly on opposite sides of the planet. The two structures, each the size of a continent and 100 times taller than Mount Everest, sit on the core, 1,800 miles deep, and about halfway to the center of the Earth.
Pregnant women in Latin American countries were more likely to seek an abortion after receiving health alerts about Zika virus, according to a study co-authored by Princeton University researchers and published in the New England Journal of Medicine.
International researchers centered at Nagoya University use a highly sensitive technique to identify significantly more DNA sequence repeats in patients with schizophrenia than in control individuals, and outline a possible link between genome instability and disease.
People who visit their primary care physicians are more likely to get potentially life-saving colon cancer screenings and follow up on abnormal stool blood test results – even in health systems that heavily promote mail-in home stool blood tests that don’t require a doctor visit, a study involving UT Southwestern population health researchers shows.
A computer program that recognises sketches pioneered by scientists from Queen Mary University of London (QMUL) could help consumers shop more efficiently.
Cold Spring Harbor, NY -- The genome of the corn plant - or maize, as it's called almost everywhere except the US - "is a lot more exciting" than scientists have previously believed. So says the lead scientist in a new effort to analyze and annotate the depth of the plant's genetic resources.
A new University of Guelph study has found that parents, and especially fathers, play a vital role in developing healthy behaviours in young adults and helping to prevent obesity in their children. When it came to predicting whether a young male will become overweight or obese, the mother-son relationship mattered far less than the relationship between father and son.
Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of structure in it.
Experts from WCS (Wildlife Conservation Society) and the National University of Singapore (NUS) have made a surprising discovery that could subvert the significance of traditional criteria used for species classification.
Researchers from the University of Houston have reported a new technique to determine the chemical composition of materials using near-infrared light.

The GRAVITY instrument is now operating with the four 8.2-metre Unit Telescopes of ESO's Very Large Telescope (VLT - http://www.eso.org/public/teles-instr/paranal/) , and even from early test results it is already clear that it will soon be producing world-class science.
The neurodegeneration that occurs in Parkinson's disease is a result of stress on the endoplasmic reticulum in the cell rather than failure of the mitochondria as previously thought, according to a study in fruit flies. It was found that the death of neurons associated with the disease was prevented when chemicals that block the effects of endoplasmic reticulum stress were used.
A new study by Simon Fraser University marine ecologists Jessica Schultz, Ryan Cloutier and Isabelle Côté has discovered that a mass mortality of sea stars resulted in a domino effect on B.C.'s West Coast Howe Sound marine ecology.
A team led by Rice University scientists has improved the production of a potent anti-tumor antibiotic known as uncialamycin.
With the help of University of Alberta scientists, a newly described pterosaur has finally flown home. This spectacular fossil material was discovered in a private Lebanese limestone quarry more than a decade ago and has led to what UAlberta paleontologist Michael Caldwell calls “priceless scientific findings.”
Traumatic experiences in childhood increase the risk of developing behavioral and psychiatric disorders later in life. It is also known that the consequences of a trauma can likewise be observed in the children of people affected even if those children have themselves not experienced any trauma. However, childhood trauma in some conditions can also help individuals deal better with difficult situations later in life. This ability, too, is passed onto following generations. These findings have recently been uncovered by Isabelle Mansuy, Professor of Neuroepigenetics at the University of Zurich and ETH Zurich, during investigations carried out in mice.
A new study by UCSB evolutionary biologists Todd Oakley and Emily Ellis demonstrates that for fireflies, octopuses and other animals that choose mates via bioluminescent courtship, sexual selection increases the number of species -- thereby impacting global diversity. Their results appear in the journal Current Biology.
Xi Chen, associate professor of earth + environmental engineering at Columbia Engineering, and Klaus Lackner at Arizona State University, reports an unconventional reversible chemical reaction in a confined nanoenvironment. The discovery, a milestone in clarifying the scientific underpinnings of moisture-swing chemical reaction, is critical to understanding how to scrub CO2 from the Earth's atmosphere; the researchers have already used it to capture CO2 more efficiently and at a much lower cost than other methods.
Our universe came to life nearly 14 billion years ago in the Big Bang — a tremendously energetic fireball from which the cosmos has been expanding ever since. Today, space is filled with hundreds of billions of galaxies, including our solar system's own galactic home, the Milky Way. But how exactly did the infant universe develop into its current state, and what does it tell us about our future?
Elementary particles are the fundamental buildings blocks of matter, and their properties are described by the Standard Model of particle physics. The discovery of the Higgs boson at the CERN in 2012 constitutes a further step towards the confirmation of the Standard Model. However, many aspects of this theory are still not understood because their complexity makes it hard to investigate them with classical computers. Quantum computers may provide a way to overcome this obstacle as they can simulate certain aspects of elementary particle physics in a well-controlled quantum system. Physicists from the University of Innsbruck and the Institute for Quantum Optics and Quantum Information (IQOQI) at the Austrian Academy of Sciences have now done exactly that: In an international first, Rainer Blatt's and Peter Zoller's research teams have simulated lattice gauge theories in a quantum computer. They describe their work in the journal Nature.
