University of Minnesota scientists are partnering with a global team to study the complex effects of climate change on winter crops.

The emergence and spread of agriculture in the Neolithic had a revolutionary impact on the development of human society, and it provided a solid economic basis for the origin and development of human civilization. In southern China, the original crop was rice, but over time, millet cultivation gradually spread. Affected by these various environmental and social developmental factors, there are still many issues about spatiotemporal detail of agriculture development in southern Anhui Province, China...

Key findings of a new Cornell University Worker Institute report mapping the low wages and poor working conditions of New York state's nail salon industry workers will be presented today (April 7) at a New York City rally calling for passage of the Nail Salon Minimum Standards Council Act.

There is perhaps nothing more evocative of the American West than herds of elk, mule deer or pronghorn moving freely across the landscape. And a new series of detailed maps reveals their migration pathways—thanks to a team of state, federal and tribal scientists.

Across languages and cultures, words that help direct caregivers' attention are likely to be among the first children learn and use frequently, according to a new Cornell study that is the largest ever, by sample size, of early vocabulary development in an Indigenous language.

Just as asking a single person about their health will provide tailored, personalized information impossible to glean from a large poll, an individual cell's genome or transcriptome can provide much more information about their place in living systems than sequencing a whole batch of cells. But until recent years, the technology didn't exist to get that high resolution genomic data—and until today, there wasn't a reliable way to ensure the high quality and usefulness of that data.

Partnerships between water utilities, irrigation districts and other stakeholders in California will play a critical role in funding new infrastructure under the Water Resilience Portfolio Initiative announced in 2020 by Gov. Gavin Newsom, but a new study warns that benefits might not be evenly distributed without proper structure to the agreements.

We often encounter nonlinear dynamical systems that behave unpredictably, such as the Earth's climate and the stock market. To analyze them, measurements taken over time are used to reconstruct the state of the system. However, this depends on the quality of the data. Now, researchers from Japan have proposed an all-new method for determining the necessary parameters that results in an accurate reconstruction. Their new technique has far-reaching implications for the field of data science.

Honey is already a thick liquid, but let it begin to crystalize and it can become downright clumpy. The sugar crystals in suspension seem to increase its viscosity. This phenomenon occurs throughout the natural and constructed world: From mudflows to paint, suspensions of particles tend to behave like viscous fluids.

Researchers have developed a new fabrication process that allows infrared (IR) glass to be combined with another glass and formed into complex miniature shapes. The technique can be used to create complex infrared optics that could make IR imaging and sensing more broadly accessible.

A team of researchers from the Singapore University of Technology and Design (SUTD) has developed a new approach for adopting the Freeform Liquid 3D Printing (FL-3DP) technology to 3D print more robust and geometrically complex components for soft robotics.

Organizational climate is key to managing the flow of proprietary knowledge within an organization and to preventing knowledge spillovers to competitors. Letting knowledge flow within organizational boundaries generates opportunity for learning and innovation. However, if knowledge spills over to competitors, it might erode competitive advantage.

Extensive technological developments, a ban on fossil fuels, less construction, fewer flights, fewer car journeys and lower levels of beef and dairy consumption. Only by taking all these measures in combination can Sweden get closer to emission levels in line with the Paris Agreement, according to a new research report commissioned by the Swedish Parliament.

The world's largest International Dark Sky Reserve is coming to Texas and Mexico, thanks to a partnership between The University of Texas at Austin's McDonald Observatory, The Nature Conservancy, the International Dark-Sky Association (IDA) and many others. The designation, granted by the IDA, recognizes the commitment of organizations, governments, businesses and residents in the region to maintaining dark skies. The move will benefit not only astronomical research, but also wildlife, ecology and tourism.

An international team, co-led by researchers at The University of Manchester's National Graphene Institute (NGI) in the UK and the Penn State College of Engineering in the US, has developed a tunable graphene-based platform that allows for fine control over the interaction between light and matter in the terahertz (THz) spectrum to reveal rare phenomena known as exceptional points. The team published their results today in Science.

Ocean water samples collected around the world have yielded a treasure trove of new data about RNA viruses, expanding ecological research possibilities and reshaping our understanding of how these small but significant submicroscopic particles evolved.

Many consumers choose higher-priced steaks, burgers and other beef products from cattle that have been raised without antibiotics. The USDA approves meat labels with claims such as 'No Antibiotics Ever', 'No Added Antibiotics' and 'Raised without Antibiotics', but how confident can shoppers be that they are, in fact, getting what they paid for

Coalescing supermassive black holes in the centers of merging galaxies fill the universe with low-frequency gravitational waves. Astronomers have been searching for these waves by using large radio telescopes to look for the subtle effect these spacetime ripples have on radio waves emitted by pulsars within our galaxy. Now, an international team of scientists has shown that the high-energy light collected by NASA's Fermi Gamma-ray Space Telescope can also be used in the search. Using gamma rays instead...

After 10 years of careful analysis and scrutiny, scientists of the CDF collaboration at the U.S. Department of Energy's Fermi National Accelerator Laboratory announced today that they have achieved the most precise measurement to date of the mass of the W boson, one of nature's force-carrying particles. Using data collected by the Collider Detector at Fermilab, or CDF, scientists have now determined the particle's mass with a precision of 0.01%—twice as precise as the previous best measurement. It... Читать дальше...

For the second year running, US scientists observed record increases in the atmospheric concentration of the potent greenhouse gas methane, the National Oceanic and Atmospheric Administration (NOAA) said Thursday.

A new study finds companies that are more aggressive in their tax planning tend to do a worse job of managing their workforce. Specifically, these companies were more likely to be "underemployed," meaning they hadn't hired enough staff to operate efficiently.

Active nanotech-based research from China has yielded several new advancements with wide-ranging applications. Newly developed nanosensors can be used to detect toxic environmental pollutants, such as chromium; novel medical technologies can be leveraged to allow point-of-care testing for clinical diagnosis and drug analysis; and they can even provide sustained and controlled drug release. Accordingly, these new technologies are expected to usher in an era of improved healthcare at the levels of prevention, diagnosis, and treatment.

After two of the most active hurricane seasons on record in 2020 and 2021, top hurricane forecasters on Thursday said we should expect another above-normal season this year.

Five years ago, the United Nations' panel on climate change was charged with drafting a series of reports detailing its science, the effects on the planet and how humanity might save itself.

Chimpanzees are known to interact with dead members of their species, revisiting corpses, and even showing mourning-like behavior. Elephants are also known to do this, and will even interact with elephant skeletons.
