BOSTON - Investments in infrastructure to promote bicycling and walking could save as many as 770 lives and $7.6 billion each year across 12 northeastern states and the District of Columbia under the proposed Transportation and Climate Initiative (TCI), according to a new Boston University School of Public Health (BUSPH) and Harvard T.H. Chan School of Public Health study.

DURHAM, N.C. -- Malaria is an ancient scourge, but it's still leaving its mark on the human genome. And now, researchers have uncovered recent traces of adaptation to malaria in the DNA of people from Cabo Verde, an island nation off the African coast.

An archipelago of ten islands in the Atlantic Ocean some 385 miles offshore from Senegal, Cabo Verde was uninhabited until the mid-1400s, when it was colonized by Portuguese sailors who brought enslaved Africans with them and forced them to work the land.

PROVIDENCE, R.I. [Brown University] -- At some point between 300 million and 1 billion years ago, a large cosmic object smashed into the planet Venus, leaving a crater more than 170 miles in diameter. A team of Brown University researchers has used that ancient impact scar to explore the possibility that Venus once had Earth-like plate tectonics.

The origin of flowering plants famously puzzled Charles Darwin, who described their sudden appearance in the fossil record from relatively recent geological times as an "abominable mystery". This mystery has further deepened with an inexplicable discrepancy between the relatively recent fossil record and a much older time of origin of flowering plants estimated using genome data.

UPTON, NY--A team of researchers led by chemists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has identified new details of the reaction mechanism that takes place in batteries with lithium metal anodes. The findings, published today in Nature Nanotechnology, are a major step towards developing smaller, lighter, and less expensive batteries for electric vehicles.

URBANA, Ill. - Getting nutrition right during a dairy cow's dry period can make a big difference to her health and the health of her calf. But it's also a key contributor to her milk yield after calving. New research from the University of Illinois shows diets containing consistent energy levels and the rumen-boosting supplement monensin may be ideal during the dry period.

Boulder, Colo., USA: Eleven new articles were published ahead of print for Geology in January 2021. The include new modeling, geochemical evidence of tropical cyclone impacts, transport of plastic in submarine canyons, and a porphyry copper belt along the southeast China coast. These Geology articles are online at http://geology.geoscienceworld.org/content/early/recent.

3D-printable resins, such as those used in dental applications, are marketed as biocompatible

Clear tooth aligners, a multi-billion-dollar industry, use these resins

Many other consumer products use 3D-printable resins

Thermoelectric materials, which can generate an electric voltage in the presence of a temperature difference, are currently an area of intense research; thermoelectric energy harvesting technology is among our best shots at greatly reducing the use of fossil fuels and helping prevent a worldwide energy crisis. However, there are various types of thermoelectric mechanisms, some of which are less understood despite recent efforts. A recent study from scientists in Korea aims to fill one such gap in knowledge. Read on to understand how!

Cities are not all the same, or at least their evolution isn't, according to new research from the University of Colorado Boulder.

These findings, out this week in Nature Communications Earth and Environment and Earth System Science Data, buck the historical view that most cities in the United States developed in similar ways. Using a century's worth of urban spatial data, the researchers found a long history of urban size (how big a place is) "decoupling" from urban form (the shape and structure of a city), leading to cities not all evolving the same--or even close.

There's a better end for used food than taking up space in landfills and contributing to global warming.

UC Riverside scientists have discovered fermented food waste can boost bacteria that increase crop growth, making plants more resistant to pathogens and reducing carbon emissions from farming.

Support for policies prohibiting smoking and the use of tobacco products on Oregon State University's Corvallis campus grew substantially over a five-year span, especially among tobacco users, a recent OSU study found.

The study, published earlier this month in the journal Preventive Medicine, is unique in its analysis of support for smoke- and tobacco-free campus policies over a long period of time. Most other studies of attitudes toward smoking policies only assess a single point in time.

Ceramic matrix composites (CMCs) are incredibly strong materials used in jet engines, gas turbines, and cutting tools for nickel superalloys. Aluminum oxide (Al2O3) is hard and chemically inert, and tungsten carbide (WC) is used as a superhard material, but past efforts to create an Al2O3-WC CMC yielded unsatisfactory results. Recently, a study by Japanese scientists, published in Scientific Reports, shows that adding zirconium atoms results in improved Al2O3-WC CMCs.

As Covid-19 continues to put pressure on healthcare providers around the world, engineers at the University of Bath have published a mathematical model that could help clinicians to safely allow two people to share a single ventilator.

Members of Bath's Centre for Therapeutic Innovation and Centre for Power Transmission and Motion Control have published a first-of-its-kind research paper on dual-patient ventilation (DPV), following work which began during the first wave of the virus in March 2020.

Reaching zero net emissions of carbon dioxide from energy and industry by 2050 can be accomplished by rebuilding U.S. energy infrastructure to run primarily on renewable energy, at a net cost of about $1 per person per day, according to new research published by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), the University of San Francisco (USF), and the consulting firm Evolved Energy Research.
