According to Bening Mayanti's doctoral dissertation at the University of Vaasa, the use of life cycle assessment combined with economic models can help companies to take steps toward the circular economy.

Frustrated that U.S. oil refineries are still allowed to dump massive amounts of toxic chemicals and heavy metals into lakes and rivers, environmental groups are urging a federal court to order more stringent regulation of some of the nation's biggest polluters.

A new perspective published in the journal Nature Chemical Biology uncovers a previously unknown biochemical recycling process in animals. The authors review a flurry of recent papers demonstrating that animals extensively recycle biochemical waste to produce novel chemicals that play key roles in biology, from regulating behavior to development and aging.

It's commonly assumed that the supply-and-demand economics of the consumer marketplace dictates price. If you are one of few retailers that sells a product consumers want, you can charge more. If supplies of that product are more scarce, prices will likely be higher. On the flip side, if supplies are plentiful for a product that is in less demand, prices for that product are likely to be lower.

The US government announced Tuesday that it is considering imposing across-the-board cuts in usage of the dwindling Colorado River, after squabbling states failed to agree on how to deal with a decades-old problem.

The Environmental Protection Agency proposed Tuesday to limit the use of the chemical ethylene oxide after finding higher than expected cancer risk at facilities that use it to sterilize billions of medical devices each year.

Cancer-causing chlorinated paraffins are still used in a wide range of everyday products sold in North America, despite their known health harm and being banned in Canada for a decade, according to a new study in Environmental Science: Processes & Impacts. The researchers detected short-chain chlorinated paraffins in more than 85% of products tested, including headphones, plastic toys, clothing,...

A new review published in Science China Chemistry has summarized recent progresses in the oxidation of methane via both thermocatalysis and photocatalysis through the lens of environmental remediation. The review was led by Prof. Junwang Tang, Department of Chemical Engineering, University College London; and Department of Chemical Engineering, Tsinghua University.

New research lead by Keith Slotkin, Ph.D., a member of the Donald Danforth Plant Science Center, opens the door for scientists to equip plants with the tools they need to adapt to rising levels of carbon dioxide (CO2), high heat, and other stressors associated with climate change. The study is published in the journal The New Phytologist .

Throughout the Arctic, fallen trees make their way from forests to the ocean by way of rivers. Those logs can stack up as the river twists and turns, resulting in long-term carbon storage. A new study has mapped the largest known woody deposit, covering 51 square kilometers (20 square miles) of the Mackenzie River Delta in Nunavut, Canada, and calculated that the logs store about 3.4 million tons...

The disastrous flood that hit Durban in April 2022 was the most catastrophic natural disaster yet recorded in KwaZulu-Natal (KZN) in collective terms of lives lost, homes and infrastructure damaged or destroyed and economic impact.

Group of Seven nations are butting heads over the timeline for phasing out coal-fired power ahead of next weekend's summit of top energy and environmental ministers.

New Mexico's budget relies heavily on oil and gas revenue, but the state also bears the scars of generations of mining and drilling. So when Antoinette Sedillo Lopez, a former law professor and current Democratic state senator, heard about the movement to add "green amendments" to state constitutions, it seemed a promising tool to address climate change and other environmental pressures in New...

As winter approached, few anticipated what was about to hit California.

Lake Tahoe's blue waters are making a significant comeback.

Thousands of dark blue creatures have been washing ashore at beaches across the state, littering the shores and bewildering passersby from Marin to Orange county.

Jouncing along to school in a fume-spewing, rattletrap yellow bus is practically a rite of passage for most American students.

The behavior of so-called "strange metals" has long puzzled scientists—but a group of researchers at the University of Toronto may be one step closer to understanding these materials.

It's a dirty job, but someone has to do it—with pride and hope.

In the United States, federal laws were created to effectively decriminalize prostitution in minors under the age of 18. However, state and local justice systems continue to arrest and incarcerate minors for prostitution, despite widespread agreement that youth involved in commercial sexual exploitation are victims, not offenders.

North Carolina State University researchers have shown that adding a small amount of a chemical used in perfumes—nonanal—to a two-chemical combination of other sex pheromones helped increase the cocktail's effectiveness in mimicking female fall armyworm "come hither" calls to males.

Have you ever had a nasty infection that just won't seem to go away? Or a runny nose that keeps coming back? You may have been dealing with a bacterium that is tolerant of, though not yet resistant to, antibiotics.

On February 6, 2023, two powerful earthquakes successively occurred in Turkey, resulting in significant damage and loss of life across southeast Turkey and northwest Syria. As a fundamental parameter, their magnitudes are of great interest to the scientific community and the general public at large.

Streams are complex habitats that can be affected by changes further upstream or downstream. Even small dams and reservoirs can modify significant ecological processes, such as fish migration and colonization.
