After years of mostly ignoring climate change, Florida lawmakers waded deeper into the matter on Tuesday , advancing a proposal that would create a statewide Office of Resiliency and establish a task force to begin looking into how best to protect the state's 1350 miles (2,173 kilometers) of coastline from rising oceans. It's a marked change from just a few years ago, when the issue of climate...

Fires started by people have steadily increased in recent decades, sparking a major shift in U.S. wildfire norms, according to a new CU Boulder-led study.
And why it’s notable that Republicans are now talking about climate change at all.
A new University of Colorado Denver study examined how information provided in a dispatched call for service influences a police officer's decision to use deadly force.
SYDNEY -- In late October, lightning struck brittle earth on Gospers Mountain in New South Wales. The remains of trees bone dry from consecutive winters with little to no rain were ignited, and the fire quickly spread.Three months later, it is still burning.The Gospers Mountain fire, which became Australia's largest "megablaze" as it grew to link several separate fires, offers a...
More countries are carrying out health checks after the virus was detected outside ChinaCountries in Asia and elsewhere are checking the body temperatures of arriving airline passengers and adopting precautionary quarantine procedures in response to a new coronavirus that has sickened nearly 300 people in China.

Scientific and public appreciation for microbes—and the key role their communal actions play in environmental health, food production, and human wellness—has grown in recent years. While initially considered to be static, uniform entities, microbial communities are highly complex and contain internal chemical swapfests that are in constant flux.
Scientists discovered dozens of new coral species on a recent voyage along the length of the Great Barrier Reef.
Scientists from Cornell University and the U.S. Department of Energy's (DOE) Brookhaven National Laboratory (BNL) have successfully demonstrated the world's first capture and reuse of energy in a multi-turn particle accelerator, where electrons are accelerated and decelerated in multiple stages and transported at different energies through a single beamline. This advance paves the way for...
Roads are dominating new housing developments, a report says, despite more people wanting to drive less.
Recent research finds that repeated flooding events have a cumulative effect on the structural integrity of earthen levees, suggesting that the increase in extreme weather events associated with climate change could pose significant challenges for the nation's aging levee system.
It takes a lot of energy to collect, clean and dispose of contaminated water. Some contaminants, like arsenic, occur in low concentrations, calling for even more energy-intensive selective removal processes.
Have I got a fish story for you. Any angler beginning a yarn like that usually ends up spinning a tall tale, an exaggeration or bald-faced lie.
Most traditional electromagnetic methods for detecting hidden metal objects involve systems that are heavy, bulky and require lots of electricity.
A team of University of Illinois researchers estimated the mortality costs associated with air pollution in the U.S. by developing and applying a novel machine learning-based method to estimate the life-years lost and cost associated with air pollution exposure.

Many drugs are derived from natural products. But before natural products can be exploited, chemists must first determine their structure and stereochemistry. This can be a major challenge, particularly when the molecules cannot be crystallized and contain only few hydrogen atoms. A new NMR-based method now simplifies the analysis and produces more accurate results.
Recent research finds that repeated flooding events have a cumulative effect on the structural integrity of earthen levees, suggesting that the increase in extreme weather events associated with climate change could pose significant challenges for the nation's aging levee system.
A hitherto unknown antibiotic-resistant bacteria species, in the same family as E. coli and Salmonella spp., has been found and classified in Sweden. The proposed taxonomic name of the species -- the first of the new genus -- is Scandinavium goeteborgense, after the city of Gothenburg, Sweden, where the bacterium was isolated and the research was done.
Scientists think that current models are incomplete and that we may be underestimating crop losses. A new study shows that infested tomato plants, in their efforts to fight off caterpillars, don't adapt well to rising temperatures. This double-edged sword worsens their productivity.
Four new species of tropical sharks that use their fins to walk are causing a stir in waters off northern Australia and New Guinea.
Scientists have reported the fabrication and use of single crystal copper-nickel alloy foil substrates for the growth of large-area, single crystal bilayer and trilayer graphene films.
A recent study suggests that maternal depression in the postpartum period, and even beyond, is associated with the development of atopic dermatitis throughout childhood and adolescence.

Have I got a fish story for you. Any angler beginning a yarn like that usually ends up spinning a tall tale, an exaggeration or bald-faced lie. Researchers, however, have demonstrated that anglers can produce accurate and complex environmental models similar to those of trained scientists.
For decades, there's been a widespread assumption among people with an interest in sports-related injury that youth football players are more vulnerable to concussion and other head injuries than their older, bigger counterparts.
Sea eagles in England | Loneliness and churches | Circumcision and Shakespeare | English usage | Sperm donationsSo a sea eagle has chosen to live in Oxfordshire (Report, 18 January). It is not the first time. Archaeologists digging near Oxford have discovered sea eagle bones on bronze age and Anglo-Saxon sites. And the name of the village Earley, on the Thames near Reading, means “eagle wood”...
Opposing desires to congregate and maintain some personal space drive fruit flies to form orderly clusters, according to a study published today in eLife.
A new technique to study the properties of molecules and materials on a quantum simulator has been discovered.
Viruses are probably the most peculiar "life forms" known to us, with each species having unique characteristics. One thing common to all viruses is that they attack a "host" cell and hijack its machinery, using it for its own replication. A type of large virus, called "giant virus," has interesting ways of attacking its host organism—an amoeba. Virologists have been trying to understand what...
The development of next-generation-sequencing (NGS) has enabled researchers to investigate genomes that might previously have been considered too complex or too expensive. Nevertheless, the analysis of complex plant genomes, which often have an enormous amount of repetitive sequences, is still a challenge. Therefore, bioinformatics researchers from Leibniz Institute of Plant Genetics and Crop...
Economists working with Professor Marko Sarstedt from Otto von Guericke University Magdeburg are demanding that the same scientific standards be applied to economics and the behavioral sciences in general as are used in the natural sciences. They believe that the inherent uncertainties in measured values must be described and quantified in order to enhance the reproducibility of measurement...
