Knowing the weight of a commodity provides a way to value goods in the marketplace. But did a self-regulating market even exist in the Bronze Age? And what can weight systems tell us? Researchers from Göttingen University investigated the dissemination of weight systems throughout Western Eurasia. Their simulation indicates that the interaction of merchants, even without intervention from institutions, is likely to explain the spread of Bronze Age technology to weigh goods.

Penn Engineers' "metallic wood" gets its useful properties and name from a key structural feature of its natural counterpart: porosity. As a lattice of nanoscale nickel struts, metallic wood is full of cell-sized pores that radically decrease its density without sacrificing strength. They have now solved a major problem preventing metallic wood from being manufactured at meaningful sizes: eliminating "inverted cracks," a kind of defect that has plagued similar materials for decades.

Article topics include the Great Unconformity of the Rocky Mountain region; new Ediacara-type fossils; the southern Cascade arc (California, USA); the European Alps and the Late Pleistocene glacial maximum; Permian-Triassic ammonoid mass extinction; permafrost thaw; the southern Rocky Mountains of Colorado (USA); "gargle dynamics"; invisible gold; and alluvial fan deposits in Valles Marineris, Mars.

Scientists and doctors at UCL Great Ormond Street Institute of Child Health (UCL GOS ICH) and Great Ormond Street Hospital (GOSH) have given hope of a gene therapy cure to children with a rare degenerative brain disorder called Dopamine Transporter Deficiency Syndrome (DTDS). The team have recreated and cured the disease using state-of-the-art laboratory and mouse models of the disease and will soon apply for a clinical trial of the therapy.

UCLA engineers have demonstrated successful integration of a novel semiconductor material into high-power computer chips to reduce heat on processors and improve their performance. The advance greatly increases energy efficiency in computers and enables heat removal beyond the best thermal-management devices currently available.

Newly published results highlight that many First Nations want access to traditional foods and environmental factors impact access to food and clean water. The study also highlights the successful partnership between First Nations peoples across Canada and academia.

A novel combination therapy resulted in a significant decrease of disease burden in an animal model of LCH.

Among low-income, uninsured, or publicly insured women ages 25-64 years who were not up to date on cervical cancer screening, 72% perceived financial barriers to screening. The most commonly reported barriers were screening appointment costs (71%) and follow-up/future treatment costs (44%).

When you think about trade and market relationships, you might think about brokers yelling at each other on the floor of a stock exchange on Wall Street. But it seems one of the basic functions of a free market is quietly practiced by fungi.

New research highlights the importance of understanding sea surface temperatures patterns in predicting future hurricane frequency.

UTSA criminology and criminal justice professors Michael R. Smith and Rob Tillyer working in collaboration with University of Cincinnati Professor Robin Engel examined racial and ethnic disparities in the use of force by the Fairfax County Police Department (FCPD). One of the nation's largest county police departments, the FCPD serves Fairfax County, Va., a major metropolitan county near Washington, D.C.

Researchers have increased the lifetime of a promising electric vehicle battery to a record level.

Simulations run by Brazilian scientists on a supercomputer at the National Space Research Institute (INPE) show that the direct impact of rising levels of carbon dioxide over the Amazon rainforest would be a reduction in rainfall equivalent to or even greater than the impact of complete substitution of the forest by pasture. The result calls attention to the need for regional and global action to mitigate the adverse effects of climate change.

A new study finds that exposure to e-cigarette vapor leads to higher levels of the coronavirus receptor ACE-2 in lungs of mice, with nicotine enhancing that increase in male mice.

Basic needs of disaster- and conflict-impacted refugees are often met by humanitarian relief goods and services, and until now little was known about how refugees create economic livelihood beyond immediate relief. A new exploratory case study from Portland State University Associate Professor of Management Theodore Khoury reveals how Syrian refugees in the Za'atari camp reached beyond basic disaster relief support and leveraged social capital to create informal economic systems that helped improve their quality of life.

While the material strontium titanate (SrTiO3) has shown immense potential as a photocatalyst in solar energy conversion, it is unclear whether chemical defects can influence its properties. Now, researchers at Nagoya Institute of Technology, Japan, looked into how doping with niobium affects the charge properties of SrTiO3 crystals. Their findings can help us to increase the efficiency of SrTiO3 photocatalysts, opening doors to a sustainable energy source.

The compound TA-C is metabolized by TB bacteria - weakening the germ from within like a 'Trojan horse' attack

Researchers expose live lobsters to vaporized cannabis and confirm the crustaceans absorb THC. Whether the psychoactive compound affects behavior remains open question.

Fireworks are synonymous in the United States with the celebration of Independence Day and other special events, but the colorful displays have caused a growing risk to public safety in recent years, according to a study by environmental health researchers at the University of California, Irvine.

Jung-Tsung Shen at the McKelvey School of Engineering has developed a groundbreaking quantum logic gate that brings quantum computing closer to reality.
