An ornate Roman chariot has been discovered "almost intact" near Italy's buried city of Pompeii, the archaeological park announced on Saturday, calling it a discovery with "no parallel" in the country.
Marine protected areas (MPAs) around Oʻahu do not adequately protect populations of herbivorous reef fishes that eat algae on coral reefs. That is the primary conclusion of a study published in Coral Reefs by researchers from the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology (SOEST).

The US city of Miami is to invest billions of dollars to tackle its vulnerability to rising sea levels, a reality that already affects the daily lives of residents used to constant flooding.
For the second time in two years, Gildardo Urrego is scooping up piles of dead bees after an invisible evil invaded his hives in northwest Colombia, wreaking havoc among his swarms.
The ability to read is foundational to education, but prolonged school closures and distance learning due to the pandemic have imposed unique challenges on the teaching of many fundamental skills. When in-person classes resume, many students will likely need a period of catch-up learning, especially those who lag behind in basic reading skills.
The ocean floor is vast and varied, making up more than 70% of the Earth's surface. Scientists have long used information from sediments at the bottom of the ocean—layers of rock and microbial muck—to reconstruct the conditions in oceans of the past.
A team of international researchers went back to the formation of the solar system 4.6 billion years ago to gain new insights into the cosmic origin of the heaviest elements on the period-ic table.
Both Democrats and Republicans overwhelmingly favor politicians who support generous COVID-19 relief spending, yet remain deeply polarized over the legitimacy of the 2020 presidential election results and former President Donald Trump's second impeachment. Meanwhile, political experts find that the former president's actions and those taken by congressional supporters in the aftermath of the...
When Patrick Rottinghaus began college, he had no idea what he wanted to do with his career. He started out as an "Open" major while he explored possibilities.
Save your silver! It's better used for jewelry than as a catalyst for drugs.
In recent years, engineers have found ways to modify the properties of some "two- dimensional" materials, which are just one or a few atoms thick, by stacking two layers together and rotating one slightly in relation to the other. This creates what are known as moiré patterns, where tiny shifts in the alignment of atoms between the two sheets create larger-scale patterns. It also changes the way...
Parasitic flatworms known as agents of food-borne zoonoses were confirmed to use several species of thiarid snails, commonly found in freshwater and brackish environments in southeast Asia, as their first intermediate host. These parasites can cause severe ocular infections in humans who consume raw or improperly cooked fish that have fed on infected snails. The study, conducted in South Thailand...
A vast iceberg almost the size of Greater London has broken away from the Antarctic ice shelf near a British research station, the British Antarctic Survey said Friday.
Whilst a great deal of research has studied the rates of photons escaping from cold atomic gases, these studies have used a scalar description of light leaving some of its properties untested. In a new paper published in EPJ B Louis Bellando, a post-doctoral researcher at LOMA, University of Bordeaux, France, and his coauthors—Aharon Gero and Eric Akkermans, Technion-Israel Institute of...
Neutron scattering is a technique commonly used in physics and biology to understand the composition of complex multicomponent mixtures and is increasingly being used to study applied materials such as food. A new paper published in EPJ E by Gregory N Smith, Niels Bohr Institute, University of Copenhagen, Denmark, shows an example of neutron scattering in the area of food science. Smith uses...
NUS scientists have devised a new method for the synthesis of nanographene molecules with a high product yield for the development of next generation quantum devices.
Who hasn't looked at the sky on a mild summer night and thought about the vastness of the universe? The trained eye can see the Andromeda galaxy as a distant spot. Thanks to the latest telescopes, we know that it consists of over a trillion stars. In the "nanocosm," clusters of individual light sources, such as molecules, also appear as points.
The Innovation Center of NanoMedicine reported in ACS Nano together with the group of Prof. Yu Matsumoto of Otorhinolaryngology and Head and Neck Surgery and the group of Prof. Horacio Cabral of the Department of Bioengineering in the University of Tokyo that the efficacy of polymeric nano-micelles with different drug activation profile depends on the expression level of c-Myc, one of the major...
Climate alone is not a driver for human behavior. The choices that people make in the face of changing conditions take place in a larger human context. And studies that combine insights from archeologists and environmental scientists can offer more nuanced lessons about how people have responded—sometimes successfully—to long-term environmental changes.
Economists and urban planners generally agree that local pollution sources disproportionally impact racial minorities in the U.S. The reasons for this are largely unclear, but a University of Illinois study provides new insights into the issue.
Scientists at UCL and the IIT—Istituto Italiano di Tecnologia (Italian Institute of Technology) have created a temporary tattoo with light-emitting technology used in TV and smartphone screens, paving the way for a new type of 'smart tattoo' with a range of potential uses.
The maternal care of offspring is one of the behavioral drivers that has led some bee species to have an ever-expanding social life over the history of evolution, new research out of York University has found.
A Mason Engineering researcher has discovered that artificial microswimmers accumulate where their speed is minimized, an idea that could have implications for improving the efficacy of targeted cancer therapy.
The koala retrovirus (KoRV) is a virus which, like other retroviruses such as HIV, inserts itself into the DNA of an infected cell. At some point in the past 50,000 years, KoRV has infected the egg or sperm cells of koalas, leading to offspring that carry the retrovirus in every cell in their body. The entire koala population of Queensland and New South Wales in Australia now carry copies of KoRV...
