BINGHAMTON, N.Y. - Contrary to long-held beliefs, humans did not make major changes to the landscape prior to European colonization, according to new research conducted in New England featuring faculty at Binghamton University, State University of New York. These new insights into the past could help to inform how landscapes are managed in the future.
Drugs for diabetes, inflammation, alcoholism -- and even for treating arthritis in dogs -- can also kill cancer cells in the lab, according to a study by scientists at the Broad Institute of MIT and Harvard and Dana-Farber Cancer Institute. The researchers systematically analyzed thousands of already developed drug compounds and found nearly 50 that have previously unrecognized anti-cancer activity.
A new type of scan that involves magnetising molecules allows doctors to see in real-time which regions of a breast tumour are active, according to research funded by Cancer Research UK* and published in Proceedings of the National Academy of Sciences today (Monday).
This is the first time researchers have demonstrated that this scanning technique, called carbon-13 hyperpolarised imaging, can be used to monitor breast cancer.
Climate change is causing the subarctic tundra to warm twice as fast as the global average, and this warming is speeding up the activity of the plant life. Researchers from the University of Copenhagen, Denmark, and the Helmholtz Zentrum München, Germany, have now elucidated how this warming affects the tundra ecosystem and the origin of an increased amount of volatile compounds released from the tundra.
The results are published in the renowned scientific journal Global Change Biology.
New research has found that environmental efforts aimed at eliminating deforestation from oil palm production have the potential to benefit vulnerable tropical mammals.
These findings, published by Conservation Letters, were drawn from an international collaboration led by Dr Nicolas Deere from the University of Kent's Durrell Institute of Conservation and Ecology (DICE), and including the University of Melbourne, University of York, Universiti Malaysia Sabah, and South East Asia Rainforest Research Partnership.
A researcher from Baltic Federal University together with his colleagues developed a composite material that can change its temperature and parameters under the influence of magnetic and electrical fields. Smart materials are safe for human health, and with these properties can be used to manufacture implants (or surface coating for them) that would work as sensors. The article was published in the Scientific Reports journal.
Terahertz radiation is used for security checks at airports, for medical examinations and also for quality checks in industry. However, radiation in the terahertz range is extremely difficult to generate. Scientists at TU Wien have now succeeded in developing a terahertz radiation source that breaks several records: it is extremely efficient, and its spectrum is very broad - it generates different wavelengths from the entire terahertz range. This opens up the possibility of creating short radiation pulses with extremely high radiation intensity.
Wildfires in south eastern Brazil produce airborne pollution that worsens air quality in major cities such as Sao Paulo - cancelling out efforts to improve the urban environment and posing health risks to citizens, according to a new study.
The planet is frequently affected by smoke from fires caused by humans and natural processes. Australia, California and other regions are prone to seasonal wildfires and smoke from wildfires and agricultural burns worsening air quality in places up to 2,000?km away.
QLED screens have been on the market for a few years now. They are known for their bright, intense colours, which are produced using what is known as quantum dot technology: QLED stands for quantum dot light emitting diode. Researchers at ETH Zurich have now developed a technology that increases the energy efficiency of QLEDs. By minimising the scattering losses of light inside the diodes, a larger proportion of the light generated is emitted to the outside.
WASHINGTON (January 20, 2020) -- Mice given a new drug targeting a key gene involved in lipid and glucose metabolism could tolerate a high-fat diet regimen (composed of 60% fat from lard) without developing significant liver damage, becoming obese, or disrupting their body's glucose balance. The study by Georgetown Lombardi Comprehensive Cancer Center researchers appeared January 20, 2020, in Cell Death and Differentiation.
While Vermonters support banning food waste from landfills - and a whopping 72 percent already compost or feed food scraps to their pets or livestock - few say they are willing to pay for curbside composting pick-up, new University of Vermont research shows.
A first of its kind, global study on the impacts of human land-use on different groups of animals has found that predators, especially small invertebrates like spiders and ladybirds, are the most likely to be lost when natural habitats are converted to agricultural land or towns and cities. The findings are published in the British Ecological Society journal Functional Ecology.
What The Study Did: An analysis of self-reported national dietary data from more than 37,000 U.S. adults suggests associations between low-carbohydrate and low-fat diets and the risk of death may depend on the quality and food sources of the carbohydrates, proteins and fats people eat. The diet scores in this observational study don't mimic particular versions of diets so the results cannot be used to assess the health benefits or risks of popular diets.
Despite reports that global emissions of the potent greenhouse gas, , were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values.
Over the last two decades, scientists have been keeping a close eye on the atmospheric concentration of a hydrofluorocarbon (HFC) gas, known as HFC-23.
New research has found preparing land for palm oil plantations and the growth of young plants causes significantly more damage to the environment, emitting double the amount of greenhouse gases than mature plantations.
