Take a close look at a house cat's eyes and you'll see pupils that look like vertical slits. But a tiger has round pupils — like humans do. And the eyes of other animals, like goats and horses, have slits that are horizontal.

Scientists have now done the first comprehensive study of these three kinds of pupils. The shape of the animal's pupil, it turns out, is closely related to the animal's size and whether it's a predator or prey.

This time of year, there’s a bevy of tomatoes, cucumbers, squash, beans, and other veggies to eat and share. Even giving them away is a challenge, as I see my neighbor cringe when I walk up their driveway with yet another gift of zucchini.

You don’t have to be an expert to see the auto industry is finally back on track. After the financial crisis several years ago and the $80 billion government bailout of GM and Chrysler, car manufacturers around the country seem to be doing quite well on their own these days.

It's summer and 90 degrees -- so why am I freezing at the office?

A recent New York Times article on air conditioning has sparked a debate on whether air conditioning is a necessity or an indulgence.

Some say air conditioning has been a part of our lives for less than a century, yet we increasingly rely on it as soon as the weather makes us feel the slightest bit uncomfortable. We're not only losing our ability to adapt, the resulting green-house gas emissions are contributing to climate change. And public buildings are way colder than they need to be for comfort.

The commissioner of Connecticut's Department of Energy and Environmental Protection said he's confident the state can comply with President Barack Obama's plan to impose stricter carbon dioxide limits on states.

An epic legal battle is about to begin over President Obama's plan to address climate change, in which the Environmental Protection Agency is putting in place new limits on greenhouse gases from power plants. Critics argue the plan is on shaky legal ground, but the administration says it's prepared to defend the regulations in court.

In announcing the "Clean Power Plan" on Monday, Obama predicted some of the arguments his critics would make.

Common Ground

Common Ground is a bit of a misnomer -- there’s not a whole lot that’s common about this high school. Started in 1997, the school uses agriculture as a key component of its curriculum.

Pesticide Drift Threatens Organic Farms

Jul 31, 2015

Chert Hollow Farm sits nestled between rows of tall trees and a nearby stream in central Missouri. Eric and Joanna Reuter have been running the organic farm since 2006. That means they don't plant genetically modified crops and can only use a few approved kinds of chemicals and fertilizers.

"We've traditionally raised about an acre and a half of pretty intensively managed produce, so it's a very productive acre and a half," Eric Reuter says.

This iridescent, copper-colored beetle hails from Japan, has been around since 1916, and is not a picky eater. Japanese beetles feast on grapes, cherries, raspberries, cannas, basil, roses, and lots of other plants. They often feed en masse, devastating plants.

On a recent visit to Kenya, President Obama proposed changes to U.S. laws governing the sale of ivory. 

The measure is largely in response to a poaching crisis that's pushing elephants, rhinos, and other species to the brink of extinction.

Connecticut was once a hub for the global ivory trade, so musicians and museums are wondering what the future holds for their ivory-containing instruments, art, and antiques.

It’s the middle of summer and for those lucky enough to live in a coastal state, like us here in Connecticut, that means it's beach time! Whether you’re looking for an inexpensive outing with the family, to catch a tan, or simply to get away from the daily grind, beaches offer it all.

White House officials hosted 13 of the largest companies from across the American economy on Monday to discuss ways business can help reduce America’s greenhouse gas emissions 26 percent over the next ten years. 

The state of Vermont and the Nuclear Regulatory Commission don't always see eye to eye. The state and the feds disagreed over the future of the Vermont Yankee nuclear plant when the Vernon reactor was operating. And now that the plant is shut down, the state has challenged the federal agency over emergency planning and decommissioning.

Connecticut's 2015 draft Wildlife Action Plan, which outlines future wildlife conservation efforts in the state, is available for public review.

The Department of Energy and Environmental Protection will accept comment on the document through August 21.

The Fish Creek Fire in Interior Alaska isn't much to look at. It's about 7,500 acres in size, sitting about an hour south of Fairbanks near the twisty Tanana River. The main fire front — the made-for-TV part, with torching trees and pulses of orange heat — flamed out more than a week ago, leaving behind a quiet charred landscape.

More than 1 million people die in traffic deaths around the world each year — that's drivers, passengers, cyclists and pedestrians combined.

It's a problem in the United States: There are 11.4 deaths a year per 100,000 population. It's a problem in low-income countries like Zambia, where the comparable figure is 23.8 deaths. And it's a huge problem in the middle-income world. The Dominican Republic records 41.7 deaths per 100,000, and was ranked in 2013 as the most dangerous country in the world for drivers.

Deepwater Wind started to put steel in the water this week for the Block Island Wind Farm. Island residents have mixed feelings about the construction.

We must really love tomatoes. Even with farmer's markets, CSAs, and farm stands loaded with fresh, locally-grown tomato fruits this time of year, we still insist on growing our own. This is even more impressive considering all the problems tomatoes can have.

There’s nothing like the beautiful blue-flowered hydrangea. Although once thought of as an old fashioned flower, hydrangeas are popular again.


On Tuesday night, astronomers got an encouraging signal from New Horizons -- after 21 hours of radio silence, the NASA probe reported it had safely made its way past Pluto. Now, scientists in Connecticut say the real work begins.

Amid complaints that planned federal rules to cut carbon emissions will hurt the economy, a new study says the northeastern states that already have moved in that direction are seeing economic benefits.

A loud boom that knocked a Rhode Island beachgoer out of her chair is still a mystery days later, leaving investigators and scientists wondering whether it was a bizarre case of nature acting up.

In 1972, there were only seven active osprey nests in Connecticut. The birds were listed as endangered or threatened in many states -- due to the widespread use of the toxin DDT, which was banned that same year.

Wayback Burgers

Gillian Maffeo said it all started as an April Fool's Day joke. Wayback Burgers, a resturant chain headquartered in Cheshire with locations across the state and country, started advertising a new type of milkshake: one infused with protein, from bugs.
