A team of international researchers led by the University of Arizona reported last year that they had uncovered the largest and oldest Maya monument—Aguada Fénix. That same team has now uncovered nearly 500 smaller ceremonial complexes that are similar in shape and features to Aguada Fénix. The find transforms previous understanding of Mesoamerican civilization origins and the relationship...

For lumber companies, the American chestnut was a nearly perfect tree—tall, straight, rot-resistant and easy to split. It also was prolific, sending up new shoots that grew quickly.

Air humidity is more important than soil moisture in influencing whether it rains in the United States Corn Belt, an agricultural area in the Midwest, stretching from Indiana to Nebraska and responsible for more than 35% of the world's most important grain crop, according to a new study by Penn State researchers.

A new paper by the Peter group of the ETH Zurich's Institute of Biochemistry (IBC) finds that the human GID E3 ubiquitin ligase forms a tetrameric complex with two distinct substrate-recruitment modules, namely WDR26-RanBP9 and GID4-ARMC8a. Although the shorter ARMC8b isoform stably assembles into the hGID complex, it lacks the ability to recruit the GID4 substrate-receptor.

Jeff Bezos' Blue Origin on Monday announced it wants to launch a space station that will house up to 10 people in the second half of the decade, as the race to commercialize the cosmos heats up.

EMBL Hamburg's García Alai Team has released eSPC, a freely available online platform for analyzing molecular biophysics data from a range of experimental techniques. The tool enables scientists around the world to easily analyze their data without the need to travel to the laboratory where the data was generated.

There are a number of G protein-coupled receptors in human cells. As an important component of the cell membrane, these proteins are responsible for detecting different stimuli in the surroundings of a cell within the body and transferring this information to the cell interior. They may act individually or in pairs, and this can have a crucial effect on their function. Together with colleagues...

In the latest edition of Physical Review B, UvA Ph.D. candidate Xuanbo Feng (QuSoft and IoP) and colleagues write about their recent experiments on a material that can go from a normal metal state to a more exotic state known as a "charge density wave state."

The sharpest images ever of living bacteria have been recorded by UCL researchers, revealing the complex architecture of the protective layer that surrounds many bacteria and makes them harder to be killed by antibiotics.

Methane emissions from the distribution and use of natural gas across U.S. cities are 2 to 10 times higher than recent estimates from the Environmental Protect Agency, according to a new study from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS).

Climate 'tipping points' can be better understood and predicted using climate change data taken from the ancient past, new research shows.

A new study, published in the Proceedings of the National Academy of Sciences (PNAS), finds that black spruce trees—a key species on the boreal landscape for millennia—are losing their resilience and capacity to regenerate in the face of warming temperatures and increasingly frequent Arctic wildfires. A continuation of this trend could result in a landscape-wide ecological shift that would...

The mechanism which allows β-lactam antibiotics, including penicillin, to kill MRSA has been revealed for the first time.

An urgent increase in policy support and investment would be needed for carbon capture and storage (CCS) to achieve the scale needed to meet global decarbonisation goals, according to University of Queensland and Princeton University researchers.

It's hard to know what climate change will mean for Earth's interconnected and interdependent webs of life. But one team of researchers at Duke University says we might begin to get a glimpse of the future from just a few ounces of microbial soup.

Lung cancer can be elusive to spot and difficult to treat because the markers for it are found in other tissues, too. Now, University of Illinois Urbana-Champaign researchers have developed a finely tuned molecular agent that can target lung and other cancer cells for imaging and treatment.

A water-borne fungus that has led to the extinction of several species of amphibians that spend all or part of their life cycle in water is also threatening terrestrial amphibians. In Brazil, researchers supported by FAPESP detected unprecedented mortality among a genus of tiny frogs known as pumpkin toadlets that live in the Atlantic Rainforest far from any aquatic environments. The animals were...

As the dominant seagrass species on the U.S. West Coast, eelgrass supports a wide range of ecosystem services and functions, making its preservation and restoration a top priority for the region. Eelgrass restoration has a spotty record of success, however, and studies of restoration sites have rarely assessed the full range of ecosystem functions.

The latest round of national emissions cutting plans submitted under the Paris Agreement will make no material dent in short-term carbon pollution levels and still put Earth on course to warm 2.7C, the UN said Monday.

A type of whale that is one of the rarest marine mammals in the world lost nearly 10% of its population last year, a group of scientists and ocean life advocates said on Monday.

Severe thunderstorms bringing record rainfall hit northern California on Monday, following several months of gigantic forest fires caused by drought.

Researchers from North Carolina State University have developed a new process that makes use of existing industry standard techniques for making III-nitride semiconductor materials, but results in layered materials that will make LEDs and lasers more efficient.

Mangrove trees straddle the boundary between land and ocean, in harsh environments characterized by rapidly changing levels of salinity and low oxygen. For most plants, these conditions would mark a death sentence, but mangroves have evolved a remarkable resistance to the stresses of these hostile locations.

A breakthrough in the fight against hunger, three Nobel Prizes, and 150 million tonnes of annual production—yet still a tricky topic for research: For over 100 years, the chemical industry has been using the Haber-Bosch process to convert atmospheric nitrogen and hydrogen into ammonia, an important component of mineral fertilizers and many other chemical products. Scientists at the...

Signs of a planet transiting a star outside of the Milky Way galaxy may have been detected for the first time. This intriguing result, using NASA's Chandra X-ray Observatory, opens up a new window to search for exoplanets at greater distances than ever before.

Researchers from Tokyo Metropolitan University have found new ways of controlling how heat flows through thin materials by stacking atomically thin layers of atoms into van der Waals heterostructures. By comparing different stacks of different materials, or even the same material after heat treatment, they found that weak coupling and mismatch between layers helped significantly reduce heat...

It is estimated that 80% of women will suffer from vaginal candidiasis at least once in their lives. In addition to superficial infections, which can be oral or vaginal and do not usually have a serious prognosis, fungi of the Candida  genus can cause systemic diseases in immunocompromised individuals and these are fatal in 40% of cases. Drugs are available to treat these conditions, but doctors...

Most elements lighter than iron are forged in the cores of stars. A star's white-hot center fuels the fusion of protons, squeezing them together to build progressively heavier elements. But beyond iron, scientists have puzzled over what could give rise to gold, platinum, and the rest of the universe's heavy elements, whose formation requires more energy than a star can muster.

If there were a classroom full of all the transition metals that could be used as catalysts for complex pharmaceutical reactions, iron would be the most promising but most unruly member.

Scientists at St Petersburg University together with researchers from St. Petersburg Federal Research Center of the Russian Academy of Sciences (SPC RAS) and the Scientific Research Centre for Ecological Safety of the Russian Academy of Sciences have developed a new organic compound demonstrating a laser-induced enhancement in its biological activity. The discovered phosphonate will enable the...

Many curious animals can be found on the Indonesian Island of Sulawesi—such as the deer-hog and the midget buffalo. But the island's tropical forests hide a diversity of tiny insects that still remains largely unexplored. Museum scientists from Indonesia and Germany have just discovered 28 new species of beetles, all belonging to the weevil genus Trigonopterus.

Ahead of COP26 in Glasgow, the University of Surrey has published a paper in Sustainability detailing how it will reduce its carbon emissions and reach Net-Zero by 2030. In the paper, Surrey's researchers share ideas and provide guidance on how other universities can apply the Science-Based Targets Initiative (SBTi). 

Plants are not entirely at the mercy of their herbivore enemies. Often, chemical defenses ensure that the plants are inedible, or even toxic, and as a result insects and other hungry animals steer clear of them. A new study has shown, for the first time, that the degradation of plants' defense substances by insects' digestive enzymes can influence the insects' preference for certain food plants....

This study is led by Dr. Bin He (College of Global Change and Earth System Science, Beijing Normal University) and Dr. Wenping Yuan (School of Atmospheric Sciences, Sun Yat-sen University). Terrestrial ecosystem, as a major carbon sink, plays an important role in regulating the global carbon cycle and atmospheric CO2 mixing ratio. Traditionally, atmospheric temperature or land water availability...

The cremation process destroys a lot of information that can usually be obtained from the human skeleton. Diseases are especially difficult to observe. This has caused a paucity in our knowledge of the disease load in populations that practiced cremation as their main funerary ritual. Dr. Barbara Veselka and Prof. Christophe Snoeck, of the Brussels Bioarchaeology Lab and research groups MARI and...

As the population of people of color grows across the United States, white Americans are still prone to move when neighborhoods diversify, and their fears and stereotypical beliefs about other racial and ethnic groups may help maintain segregation, according to research published by the American Psychological Association.

NASA's uncrewed Artemis 1 mission to the moon is on track to launch in February, the U.S. space agency said.

Nations are edging toward a deal that could create a global carbon market when they meet in Scotland for COP26 climate talks in about a week, after Brazil signaled it's willing to compromise.

Songbirds share the human sense of rhythm, but it is a rare trait in non-human mammals. An international research team led by senior investigators Marco Gamba from the University of Turin and MPI's Andrea Ravignani set out to look for musical abilities in primates. "There is longstanding interest in understanding how human musicality evolved, but musicality is not restricted to humans," says...

Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences, Peking University and Zhujiang Hospital of Southern Medical University have developed a ferritin (Fn)-based nanomedicine for targeted delivery of arsenic (As) and efficient therapy against diverse leukemia types.

Former NSW minister Pru Goward wrote a column in the Australian Financial Review last week about Australia's "underclass," who she says are lazy, dysfunctional and don't like the "discipline" of work.

Syringomyelia is a spinal cord disease characterized by fluid-filled cavities within the spinal cord tissue, which was first described over 400 years ago. However, the mechanism by which these cavities are formed is still not fully understood. In 1980, neurosurgeon Bernard Williams hypothesized that pressure changes due to coughing, sneezing, and straining, caused fluid in the cavity to "slosh"...

Brain cancer is difficult to contain and is often resistant to conventional treatment methods. Predicting tumor cell behavior requires a better understanding of their invasion mechanism. Now, researchers from University of Fukui, Japan, have used high-density nanofibers that mimic the microenvironment of the brain to capture these tumor cells, opening doors to novel therapeutic solutions for...

Earth's ocean is clearly rising. Between the loss of land and sea ice and warmer waters expanding, rising sea level is a global issue. But the equation governing exactly where the land meets the ocean also depends on the land itself. For instance, various forces such as the motion of tectonic plates can cause vertical land motion (VLM) that either exacerbates or mitigates the threat of sea level...
