Atmospheric ammonia (NH3) is a trace gas that causes environmental problems and harms human health. Chinese scientists have established a full-physical retrieval algorithm to derive the concentration of the atmospheric ammonia from the Hyperspectral Infrared Atmospheric Sounder (HIRAS) onboard the Chinese FengYun (FY)-3D satellite, presenting the first atmospheric NH3 column global map observed by the HIRAS instrument.

Recently, a research team led by Prof. Wu Zhengyan from Hefei Institutes of Physical Science, Chinese Academy of Sciences, in collaboration Binzhou Medical University, successfully designed a nanostructure that improves the detection and treatment of tumors.

When imagining corals, the picture that comes to mind is usually a stationary one: a garden of rock-like structures covering sections of the ocean floor. Reef conservation efforts typically focus on preserving established coral and protecting them from known stressors such as pollution, overfishing and runoff from coastline populations.

Climate campaigners will increasingly adopt "insider activist" roles, working to change or challenge their organizations from the inside rather than the outside, a new study says.

Most garden enthusiasts know that certain flowers can attract pollinators. New research helps explain why and also provides more details about how the nutrition found in plant pollen may determine which specific bee communities might favor your garden. On a larger scale, this research may help fight against pollinator declines through better design of rangeland restoration projects.

Under the Biden administration, there has been an effort to do a better job of measuring public and private environmental impacts. The federal government is trying to develop ways of improving the measurement of environmental costs and benefits of public investments and is also trying to stimulate the development of measures of private sector environmental impacts and risks.

A global study organized and led by Colorado State University scientists shows that the effects of extreme drought—which is expected to increase in frequency with climate change—has been greatly underestimated for grasslands and shrublands.

Well-managed migration can enable migrants to boost sustainable development, research shows. Sustainable development means enhancing well-being in ways that equitably meet needs of present and future generations.

Researchers at McMaster University have discovered a molecular "barcode" system used by disease-causing bacteria to distinguish between beneficial and toxic molecules.

In recent years, there has been rising concern that tiny particles known as microplastics are showing up basically everywhere on Earth, from polar ice to soil, drinking water and food. Formed when plastics break down into progressively smaller bits, these particles are being consumed by humans and other creatures, with unknown potential health and ecosystem effects.

Mexico's greenhouse gas emissions are the second highest among Latin American countries, trailing only Brazil according to the World Bank. But until now, no one had leveraged the full spectrum of available scientific data to make an estimate of sources (such as fossil fuel burning and agriculture) and sinks (such as healthy forests and soils) of carbon dioxide, methane, and nitrous oxide. Calculating the country's greenhouse gas budget could help policymakers develop effective emissions reduction strategies.

The number of relatives that an individual has is expected to decrease by more than 35% in the near future. At the same time, the structure of families will change. The number of cousins, nieces, nephews and grandchildren will decline sharply, while the number of great-grandparents and grandparents will increase significantly. In 1950, a 65-year-old woman had an average of 41 living relatives. By 2095, a woman of the same age will have an average of only 25 living relatives.

More than three years after New York authorities sued the National Rifle Association and four of its current and former leaders, the trial will begin on Jan. 8, 2024.

Universe Today has examined the potential for sending humans to Jupiter's icy moon, Europa, the planet Venus, and Saturn's largest moon, Titan, all despite their respective harsh environments and vast distances. These conversations with planetary science experts determined that humans traveling to these worlds in the foreseeable future could be possible, despite the harsh conditions and travel time, specifically to Titan.

It's astonishing to reflect on the swift technological progress that has reshaped the educational landscape in just the past year. In this age of creativity and innovation, the incorporation of AI into classrooms has emerged as a vital conversation.

Substitutional doping from foreign elements stands out as a preferred method for precisely tailoring the electronic band structure, conduction type, and carrier concentration of pristine materials. In the realm of three-dimensional (3D) monocrystalline silicon, for instance, the introduction of boron (B) and nitrogen (N) atoms as acceptor and donor dopants, respectively, has proven highly effective in enhancing carrier mobility. This improvement positions silicon for advanced applications in integrated circuits.

A study published in the International Journal of Business Competition and Growth has drawn insights from 621 survey samples to help improve our understanding of what elements of viral videos affect consumer behavior and purchasing decisions the most. The elements highlighted include entertainment, brand awareness, source credibility, informativeness, interactivity, and incentives.

Pollinator enthusiasts and scientists have new online tools to identify native bees in the Pacific Northwest.

Would you be happy to pour your friends a glass of wine from a cask or sip your favorite red from an aluminum can?

With hotter and drier conditions expected this summer, we can expect an increase in high fire danger days. So, it's good to be prepared. No property can ever be completely safe from bushfire, but there are some ways to address some of the weak links a bushfire may exploit. One of CSIRO's bushfire experts, Justin Leonard, has decades of experience in understanding how we can manage bushfire risk to life and infrastructure. He provides these tips to help prepare your home.

You might not think twice about using your phone while you're at work. Maybe you need to send a quick message to a family member or a friend, or catch up on the news. Then there's that dental appointment which needs to be booked—and while you're at it, you may as well get the online grocery shopping done.

Brown vs. Board of Education, the pivotal Supreme Court decision that made school segregation unconstitutional, turns 70 years old on May 17, 2024.

On a recent research trip to China, I wandered through the Oasis Mall in suburban Shanghai. Like many Chinese shopping centers, this complex was filled with empty stores that reflected the end of China's 30-year-long economic expansion. But there also were surprises.

Two local lawmakers are announcing a bipartisan effort today to regulate a toxic industrial chemical that has tainted the drinking water of thousands of people in Seminole County for years and possibly decades.

There's one thing that television viewers can count on in 2024: higher fees and more commercials.
