To Save the Amazon Rainforest, It Helps to Learn About Fish

Think of the Amazon, and you probably think of jaguars, monkeys, or parrots. But many of the rainforest’s secrets can be found hidden in its watery depths, from the fish swimming around its rivers and lakes And because these animals live in a river network that spans the South American continent, studying them helps conservationists

Earth just had hottest January since records began

Last month was the hottest January on record over the world’s land and ocean surfaces, with average temperatures exceeding anything in the 141 years of data held by the National Oceanic and Atmospheric Administration. The record temperatures in January follow an exceptionally warm 2019, which has been ranked as the second hottest year for the

Simple solar water is good for environment

A completely passive solar-powered desalination system developed by researchers at MIT and in China could provide more than 1.5 gallons of fresh drinking water per hour for every square meter of solar collecting area. Such systems could potentially serve off-grid arid coastal areas to provide an efficient, low-cost water source. The system uses multiple layers

Drop of water lighting up 100 LED bulbs

Generating electricity from raindrops efficiently has gone one step further. A research team led by scientists from the City University of Hong Kong (CityU) has recently developed a droplet-based electricity generator (DEG), featured with a field-effect transistor (FET)-like structure that allows for high energy-conversion efficiency and instantaneous power density increased by thousands times compared to

Warming is going to push farming North, releasing huge swaths of carbon stored in the soil

As the climate changes, Russia has said that it plans to “use the advantages” of rising temperatures to expand agriculture into areas where crops currently can’t easily grow. In Canada, the same migration of farmland will likely also take place. But these adaptations carry a major risk: As farming disturbs soils on northern frontiers, it could

Environment and health care

Boston’s medical establishment is coming together to carry a message to area physicians and other health care workers: Climate change plays a role in many of the illnesses they see each day. A Feb. 13 symposium, “The Climate Crisis and Clinical Practice,” at Harvard Medical School (HMS) aims to help them anticipate those health effects

State of India’s Environment report: Renewable Energy

India’s renewable energy (RE) sector seems to be losing steam, even as the total capacity has reached almost 86 GW by December 2019, says the latest State of India’s Environment Annualreport, released here at the 2020 Annual Media Conclave and Anil Agarwal Dialogue. India has set itself atarget of 175 gigaWatt (GW) RE capacity by

Red alert as Arctic lands grow greener

New research techniques are being adopted by scientists tackling the most visible impact of climate change -- the so-called greening of Arctic regions. The latest drone and satellite technology is helping an international team of researchers to better understand how the vast, treeless regions called the tundra is becoming greener. As Arctic summer temperatures warm,

Survey: Consumers keen to drop brands that damage the environment

A majority of consumers believe their choices can make a difference to environmental outcomes, and almost two-thirds are willing to abandon products and brands that are seen to damage the environment. That is the headline conclusion of a worldwide survey of over 15,000 people from 11 countries across Europe, Asia Pacific, and North America, who

Student invents sustainable polymer to keep crops hydrated

In 2013, Kiara Nirghin’s home country of South Africa was reeling from the worst drought in 30 years. The dry spell was so severe that government officials implemented strict water restrictions and declared disaster areas in five provinces. The agricultural industry was hit particularly hard as crops dried up, farmers went out of business and

Evaluating the hidden risks of herbicides

Robert Brucker grew up in rural Ohio, where farmers depend on herbicides to protect crops. Now in his lab in the Microbial Sciences Initiative at the Rowland Institute of Harvard, he studies how agrochemicals affect insects over multiple generations. “It’s important to recognize that the pesticides and herbicides we use are essential for our food

Thinning of Antarctica’s biggest glacier opposite to previous observations

They found that the pattern of thinning is evolving in complex ways both in space and time with thinning rates now highest along the slow-flow margins of the glacier, while rates in the fast-flowing central trunk have decreased by about a factor of five since 2007. This is the opposite of what was observed prior

More than a dozen states strive for 100 percent renewable energy

In 2019, Environment America and its state affiliates played a key role in convincing New Mexico, Maine and Washington to make commitments to 100 percent clean or renewable energy. On the heels of those landmark victories, the national nonprofit organization announced today it is calling on fifteen additional states in 2020 to enact similar renewable

Lab turns trash into valuable graphene in a flash

That banana peel, turned into graphene, can help facilitate a massive reduction of the environmental impact of concrete and other building materials. While you're at it, toss in those plastic empties. A new process introduced by the Rice University lab of chemist James Tour can turn bulk quantities of just about any carbon source into

Tracking complex mixtures of chemicals in our changing environment

Chemicals are the basis of life, but some anthropogenic organic chemicals pose inherent dangers. Pesticides, industrial chemicals, pharmaceuticals, and other synthetic chemicals can enter the environment and the food chain, causing unwanted effects and disease. Medical research indicates that as much as two-thirds of chronic human disease risk cannot be explained by genetics alone and
