In 2023, lawmakers across the U.S. introduced a record number of anti-LGBTQ+ bills. Although the 2024 legislative session has just begun, the American Civil Liberties Union (ACLU) is already tracking 429 bills, a figure on pace to surpass 2023 numbers.

The rapid growth of environmental data presents a significant challenge in analyzing complex pollution networks. While ML has been a pivotal tool, its widespread adoption has been hindered by a steep learning curve and a significant knowledge gap among environmental scientists.

A Northeastern University professor who found a persistent and widespread discrepancy in how often Massachusetts police ticket white drivers and drivers of color is questioning the analysis of a report released by the state Executive Office of Public Safety and Security.

Establishing an integrated ecological security pattern (ESP) is an effective way to achieve higher and more comprehensive ecological goals in the future.

After many predictions, on September 19, the Australian Bureau of Meteorology formally announced an El Niño for the summer of 2023/2024, several months after it had been declared by other international meteorological agencies.

Individually tailored RNA or DNA-based molecules are able to reliably fight off viral infections in plants, according to a new study by the Martin Luther University Halle-Wittenberg (MLU) published in the International Journal of Molecular Sciences.

The livestock industry's impact on climate change has long been a subject of concern, as detailed in the 2006 United Nations Food and Agricultural Organization's 390-page report "Livestock's Long Shadow." The report provided the first global assessment of animal agriculture's contribution to anthropogenic warming, land degradation, air pollution, water shortage and loss of biodiversity. Further, the report stated grim environmental consequences if the industry continued as usual.

Spring frosts can have devastating effects on apple production, and a warming climate may be causing trees to blossom early, making them more susceptible to the damaging effects of extreme cold events. Growers' attempts to prevent the flowers from freezing by attempting to heat the canopies of their orchards largely have been inefficient.

Vanderbilt scientist Houra Merrikh led a team of researchers who discovered the first anti-evolution chemical compound that prevents drug resistance development in bacteria. The compound is also a drug development platform that targets antimicrobial resistance during treatment of infections with antibiotics and evolution in general, Merrikh said.

Glass fiber-reinforced plastic (GFRP), a strong and durable composite material, is widely used in everything from aircraft parts to windmill blades. Yet the very qualities that make it robust enough to be used in so many different applications make it difficult to dispose of—consequently, most GFRP waste is buried in a landfill once it reaches its end of life.

An online platform powered by deep learning can predict the makeup of new psychoactive substances to help law enforcement in the fight against dangerous drugs.

Strolling along the promenade by the lake, walking through the city by the river, playing ping-pong in the park—everyday things like these are what increase our sense of well-being. Things we take for granted and around which we organize our free time—until, suddenly, the things we take for granted are no longer possible.

Researchers using a novel method of measuring long-term wildfire smoke exposure have found that Indigenous communities in California are exposed to disproportionate amounts of dangerous particulate matter—sometimes far beyond what has been previously known.

The University of Queensland has co-led a project to design a cost effective yet robust pen to expand fish farming into deeper ocean areas to help feed the growing global population. The research is published in the Journal of Marine Science and Engineering.

In a corner room of the Aerospace Engineering Sciences Building at CU Boulder, Torin Clark is about to go for a ride.

A research team led by Prof. Zhang Haimin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has conducted a systematic study on the regulation mechanism of heterostructure bimetallic phosphide electrocatalysts to improve the performance of electrochemical nitrate reduction reaction.

Internal browning (IB) is a significant post-harvest issue in pineapples, impacting fruit quality and leading to substantial losses, yet its mechanism remains poorly understood. Studies have shown that the accumulation of phenolic compounds plays a key role in tissue browning development.

As an important reproductive organ of angiosperms, flowers have a clear purpose and adaptive significance in their various characteristics. As a typical floral evolutionary feature, the floral spur is a tubular structure extending from the petal, which has undergone several independent evolutions in angiosperms (e.g., Impatiens, Aquilegia, Linaria, etc.).

Every year in the mid-latitudes of the planet, a peculiar phenomenon known as the phytoplankton spring bloom occurs. Visible from space, spectacular large and ephemeral filament-like shades of green and blue are shaped by the ocean currents.

In the context of the gradual depletion of fossil fuels and the energy crisis, hydrogen energy has attracted widespread attention due to its ultra-high energy density and eco-friendly properties. However, most of the hydrogen production still relies on fossil fuels, with less than 1 million tons produced as low-emission hydrogen in 2021, which means it has limited benefits in mitigating the energy crisis and environmental degradation.

Carbon nanotubes have shown promise for everything from microelectronics to aviation to energy storage. Researchers think this material might one day fulfill the science fiction dream of creating an elevator to space.

Central Asia has experienced a faster temperature rise than the global land over the past decades, which has brought unprecedented challenges to the survival and flourishing of life. The role of the drivers and their associated underlying mechanisms have been poorly explored.

The metabolic process of bilirubin has been a focus of medical research since the abnormal accumulation of bilirubin has been found to be associated with a variety of diseases. Bilirubin is a substance produced by the breakdown of aging or damaged red blood cells, and its effective removal is essential for human health.

Generative artificial intelligence (AI) tools are supercharging the problem of misinformation, disinformation and fake news. OpenAI's ChatGPT, Google's Gemini, and various image, voice and video generators have made it easier than ever to produce content, while making it harder to tell what is factual or real.

With media conglomerates slashing jobs, programs and publications and growing news avoidance and perceived issues of trust in journalism, finding ways to catch, engage and retain an audience has become a matter of survival for those in the news business.
