Molecular drills have gained the ability to target and destroy deadly bacteria that have evolved resistance to nearly all antibiotics. In some cases, the drills make the antibiotics effective once again.

Boeing's Starliner crew capsule finally has a launch date for its first test flight to the International Space Station.

Eastern EU members Poland, the Czech Republic and Hungary have opposed the bloc's target of zero net carbon emissions by 2050.

Since their invention more than 60 years ago, diamond anvil cells have made it possible for scientists to recreate extreme phenomena—such as the crushing pressures deep inside the Earth's mantle—or to enable chemical reactions that can only be triggered by intense pressure, all within the confines of a laboratory apparatus that you can safely hold in the palm of your hand.

Safe nuclear waste storage, new ways of generating and storing hydrogen, and technologies for capturing and reusing greenhouse gases are all potential spinoffs of a new study by University of Guelph researchers.

In today's criminal justice system, a Play Station and iPhone are just as important pieces of evidence as eyewitness accounts. Yet, there isn't a strong understanding as to how police officers identify digital evidence—everything from a laptop to a smart television—in the field.

Caribou, the North American cousin of reindeer, migrate farther than any terrestrial animal. They can cover thousands of miles as they move between winter feeding grounds and summer calving grounds. But many caribou herds are in decline as the warming climate changes much of the landscape they depend on. Inedible shrubs are rapidly encroaching on the tundra, and more frequent forest fires and...

Small insects that would normally be undetectable to bats using echolocation suddenly become detectable when they occur in large swarms. Arjan Boonman of Tel-Aviv University and colleagues present these findings in PLOS Computational Biology.

New research suggests that, when two people must work together on a physical task despite conflicting goals, the amount of information available about each other's actions influences how quickly and optimally they learn to collaborate. Vinil Chackochan and Vittorio Sanguineti of the University of Genoa, Italy, present these findings in PLOS Computational Biology.

The normal way to study cassava roots is digging up the plant. Unfortunately, that tends to kill the plant, causing serious complications for researchers who are interested in learning more about how cassava grows. To solve this, scientists at the International Center for Tropical Agriculture grew cassava in the air—using a technique called aeroponics—and in doing so removed an obstacle for...

When astronomers see something in the universe that at first glance seems like one-of-a-kind, it's bound to stir up a lot of excitement and attention. Enter comet 2I/Borisov. This mysterious visitor from the depths of space is the first identified comet to arrive here from another star. We don't know from where or when the comet started heading toward our Sun, but it won't hang around for long....

The near ubiquitous penetration of mobile phones among smallholder farmers in developing countries has enabled a powerful new tool for dispensing agricultural advice to farmers. Low acquisition and marginal costs make digital extension scalable at low cost when compared to traditional in person extension practices.

The survival of Earth's life is not a battle of humans versus nature. In this week's Science, an independent group of international experts, including one from Michigan State University (MSU), deliver a sweeping assessment of nature, concluding victory needs both humans and nature to thrive.

Strong and tough yet as light as a feather—materials with this exceptional combination of properties are urgently needed in many industrial sectors and in medicine, as well as being of great interest for scientific research. A research team from the University of Bayreuth has now developed polymer fibres with precisely these properties. Together with partners in Germany, China and Switzerland,...

At 100 feet long and weighing more than 100 tons, blue whales are the largest creatures to have evolved on the planet. Other whales, like killer whales, are larger than most terrestrial animals but pale in comparison to the size of blue whales. What sets these two weight classes of whales apart? And what is stopping the biggest whales from growing even bigger?

Today, a paper published in Science documents for the first time the global wind circulation patterns in the upper atmosphere of a planet, 120 to 300 kilometers above the surface. The findings are based on local observations, rather than indirect measurements, unlike many prior measurements taken on Earth's upper atmosphere. But it didn't happen on Earth: it happened on Mars. On top of that, all...

Night falls in Brazil's Amazon and two logging trucks without license plates emerge from the jungle. They rumble over dirt roads that lead away from a national forest, carrying trunks of trees hundreds of years old.

Leading scholars and publishers from The Ottawa Hospital's Centre for Journalology, the University of Ottawa's Telfer School of Management, and other institutions from around the world have agreed on a consensus definition of predatory publishing.

Physicists have successfully developed a new instrument that significantly reduces quantum-level noise that has thus far limited experiments' ability to spot gravitational waves. Collisions between massive black holes and stars are thought to generate these ripples in space-time that were first detected in 2015. In all, about 11 detections have been fully confirmed so far.

When do cancer-prone cells turn into full-blown cancer? A Rice University scientist and his colleague believe there's a way to know.

For viruses to multiply, they usually need the support of the cells they infect. In many cases, only in their host's nucleus can they find the machines, enzymes and building blocks with which they can multiply their genetic material before infecting other cells. But not all viruses find their way into the cell nucleus. Some remain in the cytoplasm and thus must be able to multiply their genetic...

Spider webs are one of nature's most fascinating manifestations. Many spiders extrude proteinaceous silk to weave sticky webs that ensnare unsuspecting prey who venture into their threads. Despite their elasticity, these webs possess incredible tensile strength. In recent years, scientists have expressed increased interest in the spider orb-web as a biological-mechanical system. The web's sensory...

Chinese scientists recently developed a flexible electronic skin (e-skin) capable of self-powered neural stimulation and inducing a neural response. The technology will be useful in characterizing synaptic plasticity.

Scientists from Duke University have developed a model that can predict the amount of mercury being released into a local ecosystem by deforestation and small-scale gold mining.
