Can sunlight convert emissions into useful materials?

A team of researchers has designed a method to break CO2 apart and convert the greenhouse gas into useful materials like fuels or consumer products ranging from pharmaceuticals to polymers. Typically, this process requires a tremendous amount of energy. However, in the first computational study of its kind, the research team enlisted a more sustainable ally: the sun.

COVID-19 antibodies present in patients four months after recovery: study

In previous studies, antibody levels dropped sharply within a few months after COVID-19, raising questions about the duration of immunity that infection may provide. The new finding may have implications for reinfection risks and vaccine durability, said Kari Stefansson, chief executive of deCode Genetics, which conducted the study. To get a sense of how many people in Iceland had been infected...

Large antibody study offers hope for virus vaccine efforts

Tuesday’s report, from tests on more than 30,000 people in Iceland, is the most extensive work yet on the immune system’s response to the virus and is good news for efforts to develop vaccines. If a vaccine can spur production of long-lasting antibodies like natural infection does, it gives hope that “immunity to this unpredictable and highly contagious virus may not be fleeting,”...

Fish invasions follow Panama and Suez canal expansions

World maritime trade grows each year, aided by canal waterways that connect oceans and reduce shipping time, energy consumption and carbon emissions. Following recent expansions of the Panama and Suez canals, non-native fish species are invading new habitats according to a new report in Nature Ecology and Evolution by researchers at the Smithsonian Tropical Research Institute (STRI) in Panama and...

As rural western towns grow, so do their planning challenges

A new study examines the planning challenges that residents and officials in the rural mountain American West have been watching unfold for years. The researchers specifically looked at over 1,500 'gateway communities' -- rural communities adjacent to national parks, forests, rivers and other outdoor recreational amenities.

Brazilian Amazon fires near level of 2019 crisis

The number of fires in the Brazilian Amazon last month was the second-highest in a decade for August, nearing the crisis levels that unleashed a flood of international condemnation last year, official figures showed Tuesday.

Terrawatch: how much peat is there on Earth?

Swedish researchers measure the scale of peatlands, and the amount of carbon stored in themHow much of the Earth’s landmass is made of peat? We know that peatlands store as much as a quarter of all soil carbon, and if this were to be released we would face climate havoc. Until now, however, no one had made a comprehensive map of where peatlands occurred and how deep they were. Related: Ultimate...

Study identifies effective linguistic styles for restaurant crowdfunding

Online crowdfunding is a multibillion dollar industry, but crafting a compelling pitch that stands out among thousands of projects and lands investors is challenging. This is especially true for small-scale independent restaurant concepts where, due to intense industry competition, risk is high. Kickstarter's food category can have about 30,000 active pitches at any given time, but only about 25%...

Differing diets of bonobo groups may offer insights into how culture is created

Human societies developed food preferences based on a blend of what was available and what the group decided it liked most. Those predilections were then passed along as part of the set of socially learned behaviors, values, knowledge, and customs that make up culture. Besides humans, many other social animals are believed to exhibit forms of culture in various ways, too.

Global report: schools across Europe reopen as Covid cases grow

Parents and teachers fear face masks and other measures not enough to prevent second waveCoronavirus – latest updatesSee all our coronavirus coverageTens of millions of pupils, most wearing face masks, have headed back to class in France, Belgium, Poland and Russia, as schools across Europe cautiously reopened amid spiralling numbers of new coronavirus cases in several countries.Parents and...

Resource sharing affects mortality worldwide

The act of giving and receiving increases well-being: the recipient benefits directly from the gift, and the giver benefits indirectly through emotional satisfaction. A new study now suggests that those who share more also live longer. In their analysis, researchers found a strong linear relationship between a society's generosity and the average life expectancy of its members. The researcher...

Researchers predict location of novel candidate for mysterious dark energy

Astronomers have known for two decades that the expansion of the universe is accelerating, but the physics of this expansion remains a mystery. Now, a team of researchers at the University of Hawai'i at Mānoa have made a novel prediction—the dark energy responsible for this accelerating growth comes from a vast sea of compact objects spread throughout the voids between galaxies. This conclusion...

New research provides solution for the 'Dust Bowl paradox'

Almost 100 years ago, there was a strange, slow-motion takeover of the Great Plains. During the Dust Bowl of the 1930s, as a historic heatwave and drought swept the middle of the United States, there was a dramatic shift in the types of plants occupying the region.

Memory in a metal, enabled by quantum geometry

The emergence of artificial intelligence and machine learning techniques is changing the world dramatically with novel applications such as internet of things, autonomous vehicles, real-time imaging processing and big data analytics in healthcare. In 2020, the global data volume is estimated to reach 44 Zettabytes, and it will continue to grow beyond the current capacity of computing and storage...

Notice me! Neglected for over a century, Black Sea spider crab re-described

Even though recognised in the Mediterranean Sea, the Macropodia czernjawskii spider crab was ignored by scientists (even by its namesake Vladimir Czernyavsky) in the regional faunal accounts of the Black Sea for more than a century. At the same time, although other species of the genus have been listed as Black Sea fauna, those listings are mostly wrong and occurred either due to historical...

Study finds gene targets to combat microorganisms binding to underwater surfaces

A group of synthetic biologists at NYU Abu Dhabi (NYUAD) have identified new genetic targets that could lead to safe, biologically-based approaches to combat marine biofouling—the process of sea-based microorganisms, plants, or algae binding to underwater surfaces. Biofouling continues to present significant challenges for aquaculture and sea-based commercial activities, with one of the most...

Loggerhead turtles record a passing hurricane

In early June 2011, NOAA Fisheries researchers and colleagues placed satellite tags on 26 loggerhead sea turtles in the Mid-Atlantic Bight. The tagging was part of ongoing studies of loggerhead movements and behavior. The Mid-Atlantic Bight, off the U.S. East Coast, is the coastal region from Cape Hatteras, North Carolina to southern Massachusetts. A little more than 2 months later, on August 28,...

Solar telescope GREGOR unveils magnetic details of the sun

The Sun is our star and has a profound influence on our planet, life, and civilization. By studying the magnetism on the Sun, we can understand its influence on Earth and minimize damage of satellites and technological infrastructure. The GREGOR telescope allows scientists to resolve details as small as 50 km on the Sun, which is a tiny fraction of the solar diameter of 1.4 million km. This is as...
