Ozone is a problematic air pollutant that causes serious health problems. A newly developed material not only quickly and selectively indicates the presence of ozone, but also simultaneously renders the gas harmless. The porous '2-in-one systems' also function reliably in very humid air.

A team of researchers developed a technique that uses tiny polymer spheres to sense the forces at play as body tissue forms and grows.

Bird species that live in their natural habitats can help zoos learn how to manage those in captivity, according to a new review.

Researchers brought forward the potential of high doses of a specific adjuvant molecule, namely CpG oligonucleotide, in successfully modulating the immune system's allergic response to the main cat allergen Fel d 1, thereby inducing a tolerance-promoting reaction and reverting the main hallmarks of cat allergy.

Thermoelectric generators, TEGs for short, convert ambient heat into electrical power. They enable maintenance-free, environmentally friendly, and autonomous power supply of the continuously growing number of sensors and devices for the Internet of Things (IoT) and recovery of waste heat. Scientists have now developed three-dimensional component architectures based on novel, printable...

The retreat of an Alaskan glacier in the Barry Arm fjord, caused by rising temperatures, has left a steep and hefty land mass without structural support. If the hillside collapses in a landslide, millions of tons of rock and soil will plummet into the waters below, generating a wave of water hundreds of feet tall, endangering nearby coastal towns. Perhaps even more troubling, scientists cannot...

What is common between a technology for storing energy in a solar cell and that for water purification? They both rely on the use of porous materials, or more specifically, 'nanoporous' materials that can trap gas molecules within narrow spaces on their surface, called pores, which are only nanometers (one-billionth of a meter) in size. In the parlance of chemistry, the phenomenon is known as...

Alok Sharma should resign unless plans for a deep coal mine in Cumbria are dropped, Lib Dems say.

Electrons in materials have a property known as 'spin," which is responsible for a variety of properties, the most well-known of which is magnetism. Permanent magnets, like the ones used for refrigerator doors, have all the spins in their electrons aligned in the same direction. Scientists refer to this behavior as ferromagnetism, and the research field of trying to manipulate spin as spintronics.

An international team of researchers has found what they believe to be the pathogen that has been killing chimpanzees at a Sierra Leone sanctuary for approximately 15 years. In their paper published in the journal Nature Communications, the group describes their study of multiple samples of chimp tissue retrieved from some of the dead chimps and what they have found thus far.

When the NASA Mars rover Perseverance touches down on the surface of Mars on February 18, it will arrive in Jezero Crater, which preserves evidence of a time when rivers flowed on Mars.

Plastics made from crops such as maize or sugarcane instead of fossil fuels are generally considered sustainable. One reason is that plants bind CO2, which compensates for the carbon released into the atmosphere when plastics are disposed. However, there is a catch: With increasing demand for raw materials for bioplastic production, the areas under cultivation may not be sufficient. As a result,...

Magnetism is a property of matter known by the humankind for several thousand years, long before these properties could be described in a theory. Classical magnets are metals or rare earth alloys, hard materials, such as refrigerator magnets.

The pursuit of fusion as a safe, carbon-free, always-on energy source has intensified in recent years, with a number of organizations pursuing aggressive timelines for technology demonstrations and power plant designs. New-generation superconducting magnets are a critical enabler for many of these programs, which creates growing need for sensors, controls, and other infrastructure that will allow...

A banking crisis is often seen as a self-fulfilling prophecy: The expectation of bank failure makes it happen. Picture people lining up to withdraw their money during the Great Depression or customers making a run on Britain's Northern Rock bank in 2007.

Pandemic protocols and procedures are rapidly evolving as we learn more about getting the spread of COVID-19 under control. One new tool to help us track those infected with COVID-19 may be COVID-sniffing dogs. Dr. David Dorman, professor of toxicology in the Department of Molecular Biosciences at NC State's College of Veterinary Medicine, sat down with The Abstract to talk about how dogs are able...

Mobile-phone chargers and other devices could become much smaller after an all-RIKEN team of physicists successfully shrunk an electrical component known as an inductor to microscale dimensions using a quantum effect.

Most discussions about the drawbacks of online education focus on the negative effects it has on learning. Less obvious—but also quite important—is how remote instruction can affect the teacher's use of humor.

Scientists have found that the metabolic changes that allowed whales and dolphins to adapt to their aquatic lifestyle have implications on how we should assess the impact of human activities on their conservation.

A study led by William & Mary Assistant Professor of Economics Peter Savelyev and funded by the National Science Foundation argues that college education leads to healthier and longer lives.

By reforming agriculture in targeted areas, we can protect the Natura 2000 areas much more effectively. This is what Jan Willem Erisman of Leiden University and Ton Brouwer of Gispoint consultancy write in a new report. With a special nitrogen map, they make clear in which areas in the Netherlands the most can be gained. They aim to contribute to a new and targeted nitrogen policy.

In 1972, the space race officially ended as NASA sent one last crew of astronauts to the surface of the moon (Apollo 17). This was the brass ring that both the US and the Soviets were reaching for, the "moonshot" that would determine who had supremacy in space. In the current age of renewed space exploration, the next great leap will clearly involve sending astronauts to Mars.
