A breakthrough by an Australian collaboration of researchers could make infra-red technology easy-to-use and cheap, potentially saving millions of dollars in defence and other areas using sensing devices, and boosting applications of technology to a host of new areas, such as agriculture.
Deep in vents on the ocean floor, methane-producing microbes feed off chemical reactions between water and rock. Now evidence of this process has been found on land in a freshwater spring in California.
Dartmouth College researchers are shedding light on the early chemical reactions in the organic sediments that would ultimately become the Marcellus Shale, a major source of natural gas and petroleum.
How can society plan for the future if we only look at individual issues in isolation? Climate change impact studies typically focus on a single sector such as agriculture, forestry or water, ignoring the implications of how different sectors interact. A new study, published in Nature Climate Change, suggests that an integrated, cross-sectoral approach to climate change assessment is needed to provide a more complete picture of impacts that enables better informed decisions about climate adaptation.
Artificial sweeteners help individuals with obesity to cut calories and lose weight but may have negative health effects, according to researchers at York University's Faculty of Health.
Pawpawsaurus's hearing wasn't keen, and it lacked the infamous tail club of Ankylosaurus. But first-ever CT scans of Pawpawsaurus's skull indicate the dino's saving grace from predators may have been an acute sense of smell.
Google the term “spiked drink,” and you’ll get more than 11 million hits, directing you to pages that describe being slipped a mickey, tips on how to avoid becoming a victim and even kits to test drinks for illicit drugs. So is drink spiking a growing problem or are these tales of people who just drank too much? Or is this phenomenon merely an urban legend?
In a paper published in the current Journal of Alzheimer’s Disease, researchers at University of California San Diego School of Medicine and Veterans Affairs San Diego Healthcare System say existing screening tools for mild cognitive impairment (MCI) result in a false-negative error rate of more than 7 percent. These persons are misclassified as not having MCI based on standard screening instruments but actually do have MCI when more extensive testing is conducted.
An international team of scientists, including two professors and three graduate students from UCLA, has detected and confirmed the faintest early-universe galaxy ever. Using the W. M. Keck Observatory on the summit on Mauna Kea in Hawaii, the researchers detected the galaxy as it was 13 billion years ago. The results were published in the Astrophysical Journal Letters.
Don't eat the core, it's poisonous: it's something parents often say to their children before they eat their first peach. Peach pits, which are hidden inside the nut-like husk, do in fact contain amygdalin, a substance which can degrade into hydrogen cyanide in the stomach.
A new study suggests that triclosan, an antimicrobial and antifungal agent found in many consumer products ranging from hand soaps to toys and even toothpaste, can rapidly disrupt bacterial communities found in the gut.
It's a win-win situation for the environment and the economy when it comes to introducing legumes into agricultural systems, says new research published in Frontiers in Plant Science, carried out by an international team of scientists as part of the European Union project, Legume Futures.
Two hundred and fifty million years ago, life on earth was in a tail-spin--climate change, volcanic eruptions, and rising sea levels contributed to a mass extinction that makes the death of the dinosaurs look like child's play. Marine life got hit hardest--96% of all marine species went extinct. For a long time, scientists believed that the early marine reptiles that came about after the mass extinction evolved slowly, but the recent discovery of a strange new fossil brings that view into question.
Rice University scientists have advanced their graphene-based de-icer to serve a dual purpose. The new material still melts ice from wings and wires when conditions get too cold. But if the air is above 7 degrees Fahrenheit, ice won't form at all.
University of Adelaide environmental researchers have called for a ‘code of best practice’ in using unmanned aerial vehicles (drones) for wildlife monitoring and protection, and other biological field research.
Unlike the declining populations of many fish species, the number of cephalopods (octopus, cuttlefish and squid) has increased in the world’s oceans over the past 60 years, a University of Adelaide study has found.
UCLA neuroscientists have identified in mice how the brain links different memories over time. The findings suggest a possible intervention for people suffering from age-related memory problems.
Extremely low birth weight (ELBW) babies who survive are more likely to be disadvantaged in employment, income, self-esteem, marriage and more by the time they reach their 30s. A longitudinal study has followed the ELBW survivors born between 1977 and 1982.
A hominin in the same genus as humans and an ape nicknamed “Laia” are among the discoveries identified by the SUNY College of Environmental Science and Forestry as the Top 10 New Species for 2016. Also on the list are a giant Galapagos tortoise, a seadragon, an anglerfish, three invertebrates, a carnivorous sundew and a small tree.
A large worldwide study has found that, contrary to popular thought, low-salt diets may not be beneficial and may actually increase the risk of cardiovascular disease (CVD) and death compared to average salt consumption.
Rates of neural tube birth defects were already dropping before folic acid food fortification began in the late 1990s, but the decline has since slowed, according to a large new study.
In the Mesozoic, the time of the dinosaurs, from 252 to 66 million years ago, marine reptiles such as ichthyosaurs and plesiosaurs were top predators in the oceans. But their origins and early rise to dominance have been somewhat mysterious.
Fifty-nine finfish species have ‘disappeared’ from fishermen’s catches in the world’s most species rich and vulnerable marine region, new research has shown.
Sexual conflict between males and females can lead to changes in the shape of their genitals, according to research on burying beetles by scientists at the University of Exeter.
Managers who inspire their staff to perform above and beyond the call of duty may actually harm their employees’ health over time, according to researchers from the University of East Anglia.
Spotting native alligators and crocodiles in Florida is common, but anyone who sees a large reptile may want to take a second look -- man-eaters that can grow to 18 feet long and weigh as much as a small car have been found in the Sunshine State.
A new study provides the first-ever evidence that women who reveal personal family-related information that could explain gaps in their resume (like staying home to raise a child) dramatically raise their chances of getting hired compared to a women who focus on their resume credentials alone.
Many breast cancers are marked by a lack of HOXA5 protein, a gene product known to control cell differentiation and death, and lower levels of the protein correspond to poorer outcomes for patients. Now, results of a new study by Johns Hopkins Kimmel Cancer Center scientists suggests a powerful role for the protein in normal breast cells, acting as a tumor suppressor that halts abnormal cell growth.
Evolution can be an emotionally charged topic in education, given a wide range of perspectives on it. Two researchers from Arizona State University are taking an in-depth look at how college professors handle it.
The importance of friendships and family support in helping prevent depression among teenagers has been highlighted in research from the University of Cambridge. The study, published in the open access journal PLOS ONE, also found that teenagers who had grown up in a difficult family environment were more likely than their peers to be bullied at school.
It is possible to significantly slow down and even temporarily stop the progression of global warming by increasing the atmospheric aerosol concentration, shows a new study from the University of Eastern Finland. However, climate engineering does not remove the need to reduce greenhouse gas emissions.
The aim of the study provided by the Master of Arts (Education), Erja Sandberg, was to collect and describe the experiences of Finnish families in which the symptoms of ADHD such as attention deficit, hyperactivity and impulsiveness are strongly present. Over 200 families participated in the study sharing their experiences of the support provided by educational, social and health sectors as well as the co-operation between these different bodies.
Scientists have mapped changes in composition of plant cell walls over space and time, providing new insights into the development and growth of all plants.
Two-way communication between cancer cells appears to be key to their becoming motile, clustering and spreading through metastasis, according to Rice University scientists.
While a reported drop in obesity rates among U.S. children has been heralded as positive news, more work must be done to understand exactly why that drop occurred, according to researchers at Rice and Temple universities.
A study published today by researchers at the University of Southern California (USC) Roski Eye Institute in JAMA Ophthalmology found that the U.S. prevalence in visual impairment (VI) and blindness is expected to double over the next 35 years. By 2050, the number of Americans with a variety of eye disease and impairment issues, including age-related macular degeneration (AMD), glaucoma, diabetic retinopathy (DR) and cataracts, will dramatically increase impacting both individuals and society.
The geologic shape of what were once shorelines through Mars’ northern plains convinces scientists that two large meteorites – hitting the planet millions of years apart – triggered a pair of mega-tsunamis. These gigantic waves forever scarred the Martian landscape and yielded evidence of cold, salty oceans conducive to sustaining life.
Interventions designed to reduce alcohol use among fraternity members are no more effective than no intervention at all, according to an analysis of 25 years of research involving over 6,000 university students published by the American Psychological Association.
