An oil spill in eastern Ecuador has reached a nature reserve and polluted a river that supplies water to indigenous communities, the country's environmental ministry said Monday.

Bulldozers digging for an Egyptian-funded housing project in the Gaza Strip unearthed the ruins of a tomb dating back to the Roman era, Hamas authorities said Monday.
When it comes to measuring global warming, humidity, not just heat, matters in generating dangerous climate extremes, a new study finds.
Access to the gig economy may help facilitate the creation of new businesses, according to a new study.
As the world searches for and demands more sustainable sources of energy and materials, plant biomass may provide the solution by serving as a renewable resource for biomaterials and biofuel production. However, until now, the complex physical and chemical interactions in plant biomass have been a challenge in post-harvest processing.
The first report of its kind in Canada to examine how women use public transit suggests their travel needs aren't always being met by standard planning and service models.
With new algorithms and supercomputers, an incredibly detailed radio map of the universe has been created. Now astronomers can look at radio data of galaxies with much more precision. This research was published in Nature Astronomy by Leiden University Ph.D. student Frits Sweijen and colleagues.
When did the Earth reach oxygen levels sufficient to support animal life? Researchers from McGill University have discovered that a rise in oxygen levels occurred in step with the evolution and expansion of complex, eukaryotic ecosystems. Their findings represent the strongest evidence to date that extremely low oxygen levels exerted an important limitation on evolution for billions of years.
Even fans of black-and-white film can't deny that color brought new life to photography and motion pictures. And when it comes to learning what happens inside the body, there's no substitute for color. Were it possible, for example, to map out real-time gene expression in our body's cells using contrasting colors, scientists would gain a glimpse of vital biological processes that are currently...
Antibiotics have allowed for the widespread control of bacterial infections, which had been the leading cause of death historically. However, the overuse of traditional antibiotics in humans and animals has resulted in the emergence of stronger, more potent bacterial strains that are no longer treatable with conventional antibiotics.
Oxygen and sugar are the basis of life for animals, plants, fungi and many bacteria. The metabolic process called respiration makes it possible to convert food into energy for the cells. Biochemist Prof. Dr. Carola Hunte and her team from the Cluster of Excellence CIBSS at the University of Freiburg have now visualized for the first time with unparalleled precision how an assembly of protein...
Why do some young men turn to crime, while others don't? An international study shows that preferences such as risk tolerance, impatience and altruism as well as self-control can predict who will commit crime. Risk-tolerant, impatient young men are more likely to commit property crime, while people with low self-control tend to commit violent, drug and sexual offenses.
A new study involving more than 100 scientists from across the globe and the largest forest database yet assembled estimates that there are about 73,000 tree species on Earth, including about 9,200 species yet to be discovered.
A new study by a team of researchers from Israel and Ghana has brought the first evidence of nonrandom mutation in human genes, challenging a core assumption at the heart of evolutionary theory by showing a long-term directional mutational response to environmental pressure. Using a novel method, researchers led by Professor Adi Livnat from the University of Haifa showed that the rate of...
Researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have used microscopic strands of DNA to guide the assembly of gel blocks that are visible to the naked eye.
Rice University scientists are using machine-learning techniques to streamline the process of synthesizing graphene from waste through flash Joule heating.
Beef producers in the upper Midwest know grazing land is in short supply. With more acres being developed or converted to cropland, producers who want to expand their cow-calf operations are looking for alternatives to traditional pasture management.
New research suggests that ancient trees possess far more than an awe-inspiring presence and a suite of ecological services to forests—they also sustain the entire population of trees' ability to adapt to a rapidly changing environment.
Two researchers from the University of Ottawa are the first to map out all the glaciers that end in the ocean in the Northern Hemisphere and provide a measure of their rate of change over the last 20 years. Their findings will help better understand—and perhaps predict—the impact of climate change north of the equator.
The carbon material graphene has no well-defined thickness; it merely consists of one single layer of atoms. It is therefore often referred to as a "two-dimensional material." Trying to make a three-dimensional structure out of it may sound contradictory at first, but it is an important goal: if the properties of the graphene layer are to be exploited best, then as much active surface area as...
A team of researchers working at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research has found via models, that due to a long lag time, the Greenland ice sheet could continue losing ice over the next century whether global warming is brought under control or not. They have posted a paper describing their findings in the open-access journal PLOS ONE.
With the approaching snowstorm predicted to dust the Baltimore area and blanket the Eastern Shore while creating dangerous conditions into Saturday morning, state highway crews and local transportation departments spent Friday preparing the roads.
The carbon stock in managed boreal forest landscapes is increasing, while it is relatively unchanged in less intensively utilized forests where carbon losses due to forest fires have instead been significant during 1990-2017, according to a new report by the International Boreal Forest Research Association (IBFRA).
French authorities said Monday they would begin testing limited daily permits to visit one of the most pristine coves near the Mediterranean city of Marseille, where summer crowds have sharply increased erosion risks.
You might think hibernation is just a nap that bears take during the wintertime, but it's really much more complicated and climate based.
