Climate change is poised to affect the world's food supply in three key ways, experts say. "There will be impacts on the quantity, quality and location of the food we produce," said Dr. Sam Myers, a medical doctor and senior research scientist studying environmental health at the Harvard T.H. Chan School of Public Health. "We've never needed to increase food production more rapidly than we do today to keep up with global demand," Myers told Live Science.

There was never a peaceful past where everyone got along in prehistoric North American societies - small-scale societies in what is now central California were quick to become violent when food and other resources were scarce, an archaeological study finds. Bludgeoning, a close-contact form of violence, was not related to resource scarcity. The bodies of five per cent of females and 11 per cent of males had marks of violence, such as arrow wounds, stab wounds or evidence of being bludgeoned.

A Japanese zoo has culled 57 native snow monkeys by lethal injection after finding that they carried genes of an "invasive alien species", officials said Tuesday. The Takagoyama Nature Zoo in the city of Futtsu in Chiba prefecture east of Tokyo, housed 164 simians which it believed were all pure Japanese macaques. A city official told AFP on Tuesday that Japanese law bans the possession and transport of invasive species, including the crossbreeds, and that culling of them is allowed under the law.

Gene editing, which has raised ethical concerns due to its capacity to alter human DNA, is being considered in the United States as a tool for improving livestock, experts say. The technique is different than that used in genetically modified organisms (GMOs) because it does not introduce foreign genes, but rather alters already existing DNA. "Gene editing is one of the newest and most promising tools of biotechnology," Alison Van Eenennaam, an expert in animal genetics and biotechnology at the University of California, Davis, told the annual meeting of the American Association for the Advancement of Science.

BOSTON - Hundreds of science-minded demonstrators converged on Boston over the weekend to test a prototype for the March for Science, a campaign that's expected to bring out more than a million people around the globe on April 22. Sunday's "Stand Up for Science" rally took place during the height of this year's meeting of the American Association for the Advancement of Science, and as a result drew attendees from the AAAS crowd - including Bish Paul, a molecular biologist who got his Ph.D. from the University of Washington and worked at Seattle's Fred Hutchinson Cancer Research Center. Paul, a gay immigrant from… Read More

"We are either kings or pawns of men," said Napoleon Bonaparte. In his famous quote, he describes possibly the biggest challenge facing humanity as we move into a world driven by ever smarter, more manipulative technology. As technology advances, we are quickly becoming slaves to it, unaware of our intentional manipulation.

The consequences of using the wrong exit out of a shopping center are minimal, but when it's a firefighter trying to make her way out of a burning building, the stakes for tracking her precise location and orientation are high. A system is being developed at NASA's Jet Propulsion Lab (JPL) with funding from the Department of Homeland Security (DHS) to track first responders accurately and in real time in spaces-such as buildings made of steel and concrete-where GPS and other technologies fail. The primary goal of the new system-Precision Outdoor and Indoor Navigation and Tracking for Emergency Responders, or POINTER-is to save the lives of those whose job it is to save lives.

Scientists believe they've found a viable way to extract uranium from the oceans, opening up a source of energy that could supply today's nuclear power stations for 6,000 years. Researchers from Stanford University have developed a technique that, they believe, will give us the option to extract nuclear fuel from seawater. There is an enormous quantity of uranium in the oceans, around 4.5 billion tonnes, in the form of uranyl ions with a positive charge.

Lemurs are considered the world's most endangered mammal, but a team of researchers have devised a system called LemurFaceID, which uses facial-recognition software to spot lemurs in their natural habitat.

The "Tully Monster" was probably not a vertebrate, scientists have said, contradicting the conclusions of two other high-profile studies published last year. The Tully Monster is an iconic 300 million year-old, soft-bodied fossil from the Mazon Creek fossil beds in the USA. It was first discovered by amateur palaeontologist Francis Tully in 1958, but many other specimens have been found since then.

The origins of handedness have been a scientific puzzle for many years. Asymmetries in the brain have been thought to be the source of our preference for either our right or left hands. Instead, even earlier in development there is asymmetrical expression of genes in the spine, which is now thought to be where handedness arises, according to a paper in the journal eLife.
