Environmental Studies

A marine biology class at Monmouth University has been studying how recent nor'easter storms affect mole crab populations along the New Jersey shore. Students are measuring crab abundance before and after the storms to see how these powerful coastal weather events reshape beach ecosystems and the small crustaceans that live in the surf zone.

Students preparing for the Higher Secondary Class 12 Semester 3 Environmental Studies exam are looking at possible questions and answers for the 2027 test. Study materials with model EVS questions are drawing heavy attention as learners under the semester system seek guidance on what the environment studies paper may cover and how to prepare for it.

Volunteers known as 'Rat Rangers' in Washington, DC are leading evening walks through alleys to teach residents that better sanitation is the key to rodent control. Around two dozen neighbors learn about rat biology and the damage caused by poison. The group formed after a 2024 study found rodenticides in local wildlife, prompting a push for non-chemical solutions.

A new report finds that just 3% of questions raised in India's Parliament over ten years addressed climate issues. The study also found the government repeatedly took a cautious stance on linking environmental damage, particularly air pollution, to rising death rates or specific illnesses. Critics say the figures point to limited parliamentary scrutiny of climate and public health risks.

New research suggests that living environment and lifestyle factors in early adulthood may accelerate biological aging, meaning some people in their twenties and thirties could be biologically older than their actual age. The findings point to conditions such as surroundings and daily habits as influences on how quickly the body ages, drawing attention to health risks that emerge long before later life.

West Bengal's higher secondary board, WBCHSE, held the Semester-3 Environmental Studies (EVS) examination for Class 12 students on September 29, 2026. Coaching channels and educators have been sharing question paper reviews and suggested answers to help students estimate their performance. Students across the state are discussing the paper's difficulty and expected scores following the exam.

NASA has published a new Curiosity rover blog covering Sols 5016-5021 on Mars, titled 'Fantastic Minerals and How To Detect Them'. The update describes how the rover's instruments are being used to identify minerals in the rocks it is studying, offering fresh insight into the Red Planet's geology and past environmental conditions.

New research suggests that a person's living environment and lifestyle habits may already accelerate biological ageing in early adulthood, not just later in life. The findings point to factors such as surroundings and daily habits influencing how fast the body ages biologically. The topic is drawing attention as it highlights health risks starting well before middle age.

The emerging field of exposomics — the comprehensive study of every environmental exposure a person experiences over a lifetime, from pollution and diet to stress — is being examined as a missing link in personalized medicine. Researchers argue that genetics alone cannot explain most disease risk, and mapping the exposome could make truly individualized prevention and treatment possible.

A new study examines how climate change is affecting skin health around the world, pointing to rising temperatures, increased UV exposure and environmental shifts as factors influencing skin conditions. Details of the research, including where it was published and its specific findings, are limited so far, but the topic is drawing attention in health and beauty industry circles.

A new climate change study will examine the Pinelands in Burlington County, New Jersey, according to a report by The Philadelphia Inquirer. The research will focus on how climate change is affecting the ecologically sensitive pine barrens region, which spans large parts of southern New Jersey. Details on the study's scope, timeline and funding were not provided in the initial report.

New research reported by Newswise suggests that a person's childhood family environment, including the number of siblings they grew up with, may influence their heart and brain health in middle age. The findings point to early-life conditions as possible long-term factors in cardiovascular and cognitive wellbeing, adding to growing evidence that health risks can take root decades before symptoms appear.

A new study of fracking operations, reported by Spotlight PA, found low levels of radium in wastewater but raised concerns about high salt content. Researchers suggest the salty brine brought up by drilling could pose risks to groundwater and streams if spilled or improperly handled, shifting attention from radiation to salinity as the main environmental worry.

The US Environmental Protection Agency is working to accelerate its chemical safety reviews while reducing reliance on animal testing, according to Bloomberg Law. The agency's chemical science office is pursuing faster assessment methods, likely including new approach methodologies that replace animal studies. The effort affects industries seeking approval of chemicals under federal toxics law, though details of the initiative remain limited in early coverage.

Students preparing for the Higher Secondary third semester Environmental Studies exam are sharing suggested questions and model papers ahead of the 2026-2027 assessment cycle. Coaching centres are circulating expected question papers for Class 12 semester 3 EVS, and learners are using them to focus revision on likely topics as the semester exams approach.

A Tulane University researcher has been awarded a $3.7 million grant from the National Institutes of Health to study how heat and wildfire smoke exposure may be linked to autism risk. The funding will support research into environmental factors that could contribute to the condition, a topic of growing scientific and public interest as climate change intensifies heatwaves and wildfires across the United States.

A new study suggests that fruit flies exposed to dead members of their own species may age faster, offering a possible window into how sensing death affects biological aging. The findings, reported by Vietnamese outlet VnExpress International, add to research on how environmental cues influence lifespan in insects.

A new study reports that pastoralist communities in Uganda are increasingly relying on wild plants to cope with food shortages. Researchers say the shift highlights how climate pressures and declining livestock livelihoods are pushing herders to forage for alternative food sources. The findings raise concerns about food security and nutrition in Uganda's pastoral regions, where drought and environmental change continue to disrupt traditional ways of life.

French utility EDF has deployed a floating platform designed to carry out environmental studies at sea. The platform is intended to support marine monitoring work, likely in connection with offshore energy projects. Details about its location, duration and specific research objectives have not been disclosed. Environmental monitoring of this kind is commonly required ahead of offshore wind developments.
