The Great Pacific Garbage Patch
The Pacific Ocean hosts the largest trash dump on Earth. It is called the Great Pacific Garbage Patch and it’s at least as big as Texas but might be much larger. Estimates are that it holds more than 3.5 million tons of garbage and at least 80% of it is plastic. [Read more…] about The Great Pacific Garbage Patch
Growing numbers of electric cars
As of early this year, the number of electric cars in the world has passed the 400,000 mark. This represents a doubling of the number from just 12 months ago, which in turn was a doubling of the previous year’s total. There is no doubt that there is sharp and steady growth in electric vehicles. [Read more…] about Growing numbers of electric cars
Saving the bees

In recent years, bee populations have been shrinking at an alarming rate. According to the Department of Agriculture, managed honeybee colonies lost almost a quarter of their numbers over the past winter alone. These rapid declines in bees and other pollinators in the United States threaten billions of dollars in crops. [Read more…] about Saving the bees
The warm Pacific caused our weird winter

Last winter was one of the coldest on record in the American Midwest. Northeastern cities were buried in snow. Meteorologists kept talking about the “polar vortex”. And meanwhile, western states were unseasonably warm and were stricken by drought. By all accounts, it was a weird winter. [Read more…] about The warm Pacific caused our weird winter
Cleaning up with fungus

Dealing with contaminated soils in industrial and former industrial sites is a continuing problem for society. People employ a variety of methods for removing or remediating persistent organic chemicals in these places. Techniques such as capping, excavation, and even incineration have all been used at one point or another. All the methods have their problems and most are quite expensive.

Ecosystems need predators

Salt marshes are extremely important ecosystems. They shield coasts from flooding, they remove pollutants from water, and they are the baby nurseries for many kinds of fish. In recent years, salt marshes in places like the coastlines of New England have been dying off. [Read more…] about Ecosystems need predators
Solar jet fuel
Transportation accounts for more than a quarter of the world’s energy consumption and most of that is in the form of ordinary gasoline. Jet fuel, which is primarily composed of kerosene, accounts for about 6% of refinery production worldwide but contributes about 12% of CO2 emissions. Jet fuel is also a big part of airlines’ operating costs. As a result, there are good reasons to seek sustainable and economical alternatives. [Read more…] about Solar jet fuel
Seashells

Whether you’re a collector or just a casual beachgoer, you’ve probably bent to pick up a seashell that caught your eye. Children scour the beach for unique shells, and vacationers pocket them as mementos of their travels. Few things seem more innocent, but what is the impact of all those disappearing shells? [Read more…] about Seashells
Cars sharing the grid
Last year, Americans bought almost 100,000 cars that plug into the wall. That is a drop in the bucket in the overall auto market, but the number of electric cars is growing rapidly year-by-year. People are starting to wonder what might happen when a huge number of cars need to share the power grid. [Read more…] about Cars sharing the grid
Keeping a pulse on the Hudson River
Technology has transformed our ability to understand rivers. Take the Cary Institute’s longstanding scientific program on the Hudson River. In the past, to get measurements on environmental conditions, we relied on researchers sampling in boats. Not only is this expensive and time consuming– it isn’t feasible in bad weather. [Read more…] about Keeping a pulse on the Hudson River
Honeybees and environmental health
There are many ways to evaluate the health of a landscape. A new study suggests one way may be to listen to dancing honeybees. Of course, the bees aren’t dancing because they’re happy– rather, they use their signature waggle dance as a way to communicate to one another where the best food can be found.

Offshore wind turbines can slow hurricanes
Wind power is welcomed by farmers and ranchers in the Great Plains for the income and economic activity it brings, but it has made much slower progress in the densely populated Northeast. Here, residents often object to wind turbines disrupting their views of formerly pristine ridge-lines, and offshore wind runs into objections from politically powerful owners of beachfront property. [Read more…] about Offshore wind turbines can slow hurricanes
New EPA standards benefit our health
The Environmental Protection Agency recently announced a plan to significantly reduce carbon dioxide emissions from power plants by the year 2030. This is excellent news for the environment, as power plant emissions cause global warming, acid rain, mercury poisoning in fish and wildlife, and ozone damage to crops and trees. [Read more…] about New EPA standards benefit our health
Summertime ozone
Ozone is a puzzling air pollutant. Human activities are not direct sources of a lot of ozone, but ozone concentrations increase to markedly unhealthy levels in many areas during the summer. About 30 years ago, atmospheric chemists solved this mystery. [Read more…] about Summertime ozone
Microbeads
When we think about protecting our waterways from plastic pollution, we think of recycling water bottles or moving toward canvas grocery bags. But what about the plastics we can’t see? [Read more…] about Microbeads
Science and art
Science and art are rarely thought of as going hand-in-hand. In fact, we typically think of scientists and artists as having entirely different type of brains – one logical and analytical, the other creative and subjective. [Read more…] about Science and art
Death by air pollution
The human health effects of air pollutants are hotly debated. Since air pollution is typically a long-term, diffuse problem, it is difficult to link human mortality to any particular air pollutant. Studies of the human health effects of acute chemical spills are much easier. [Read more…] about Death by air pollution
Wasting food
Scientists have long been concerned about potential food shortages in a world facing climate change and a rapidly increasing population. [Read more…] about Wasting food
