Since March, several infants in Connecticut have died at home daycares – resulting in police investigations and heightened concern among parents.

This hour, we talk about child care – many of us rely on it, how do we keep it safe?

Scientists in Michigan have found a new dwarf planet in our solar system.

It's about 330 miles across and some 8.5 billion miles from the sun. It takes 1,100 years to complete one orbit.

But one of the most interesting things about the new object, known for the time being as 2014 UZ224, is the way astronomers found it.

Politics plays a role in all sorts of things in life: dating partners, how we think about the economy, and, according to Eitan Hersh, the choices doctors make.

This is the way the Rosetta ends: not with a bang, but with a slow-motion crash.

The historic spacecraft has transformed scientists' understanding of comets over the past two years, as it orbited the 67P/Churyumov-Gerasimenko comet and sent a stream of images and data back to Earth.

Now scientists have steered it into the comet for a "Grand Finale" of data-collection, and Rosetta has lost contact with Earth forever.

It has been a common belief that low-emissions vehicles, like hybrids and electric cars, are more expensive than other choices. But a new study finds that when operating and maintenance costs are included in a vehicle's price, cleaner cars may actually be a better bet.

The cars and trucks we drive are responsible for about a fifth of greenhouse gas emissions in this country. That's why Jessika Trancik, an energy scientist at the Massachusetts Institute of Technology, decided it was time to take a closer look at vehicle emissions.

Teen pregnancy rates in the U.S. have reached historic lows, according to the latest data from the Centers for Disease Control and Prevention, declining more than 40 percent from 2006 to 2014.

Newly released FBI data show the number of murders in the U.S. rose nearly 11 percent last year and violent crime increased by nearly 4 percent, but crime researchers said homicides and other violence still remain at low rates compared with a crime wave from 20 years ago.

The Commercial Fisheries Research Foundation is kicking off a new project to collect data on black sea bass, a species that has moved north in search of cooler water.

This year marks an important milestone in our nation's history -- 35 years since the discovery of HIV/AIDS. This hour, we look back to see how far we've come in understanding, treating, and destigmatizing HIV/AIDS in America.

This hour, we look at the impact of climate change on New England's native plant and animal species. We talk with scientists and science journalists, and we hear from you. Have you noticed anything different about the flora and fauna in your backyard? And what can historical records -- like the observations of naturalist Henry David Thoreau -- teach us about our changing environment?

Colin has a "pet" raccoon that visits his porch. The raccoon will press her tiny paw up against the outstretched palm of Colin's significant other, which rests on the indoor side of the glass. Eventually, the raccoon gets a bit of food because "she" is too cute to resist. The pleased raccoon now visits on a regular basis. Colin fears this cannot end well.

A more than 160-year-old Arctic mystery has come to resolution: The HMS Terror, a vessel from a doomed Royal Navy exploration to chart an unnavigated portion of the Northwest Passage, has been found, Aleta Brooke, operations manager for the Arctic Research Foundation said.

The Guardian, which first reported the story, said the vessel is in "perfect condition." The paper reports:

Five states are voting this fall on whether marijuana should be legal, like alcohol, for recreational use. That has sparked questions about what we know — and don't know — about marijuana's effect on the brain.

Connecticut’'s medical marijuana program is proving to be a success. The program has been up and running since 2014 with more than 12,000 patients and a growing list of certified doctors, according to the Department of Consumer Protection. 

Newly released government data paint a sobering picture of safety on the nation's roads and highways.

In 2015, the number of people who died in auto accidents reached 35,092, says the National Highway Traffic Safety Administration, a 7.2% increase over 2014. The last time there was such a large single-year increase was back in 1966 when Lyndon Johnson was president.

State officials are preparing to respond if there are any signs the Zika virus is being transmitted in Connecticut. Experts from several state agencies met Wednesday to put together a plan to combat the spread of the disease.

Why are some people more susceptible to addiction than others? How does genetic makeup influence a person’s chances of becoming an addict? This hour, we find out how researchers at Yale University and The Jackson Laboratory are working to better understand the science of addiction. 

The Obama administration has denied a bid by two Democratic governors to reconsider how it treats marijuana under federal drug control laws, keeping the drug for now, at least, in the most restrictive category for U.S. law enforcement purposes.

Rhode Island Keeps Tabs on Zika

Aug 9, 2016

The Rhode Island Health Department has confirmed 18 cases of Zika virus -- a disease linked to a severe birth defect called microcephaly. 

The National Centers for Disease Control and Prevention report all of the Rhode Island cases were contracted outside of state lines. 

The mosquito known to carry Zika in Florida is not established in Rhode Island. However, the state may be at risk for another mosquito which also carries the virus. 

The federal government announced plans Thursday to lift a moratorium on funding of certain controversial experiments that use human stem cells to create animal embryos that are partly human.

The National Institutes of Health is proposing a new policy to permit scientists to get federal money to make embryos, known as chimeras, under certain carefully monitored conditions.

'Clone Sisters' Of Dolly The Sheep Are Alive And Kicking

Jul 26, 2016

About four years ago, Kevin Sinclair inherited an army of clones. Very fluffy clones.

"Daisy, Debbie, Denise and Diana," says Sinclair, a developmental biologist at the University of Nottingham in England.

The sheep are just four of 13 clones Sinclair shepherds, but they're the most famous because of their relation to Dolly, the sheep that made headlines two decades ago as the first successfully cloned mammal.

NASA has released the first picture of Jupiter taken since the Juno spacecraft went into orbit around the planet on July 4.

The picture was taken on July 10. Juno was 2.7 million miles from Jupiter at the time. The color image shows some of the atmospheric features of the planet, including the giant red spot. You can also see three of Jupiter's moons in the picture: Io, Europa and Ganymede.

We’re humans, so we tend to think -- not surprisingly -- about Earth first. 

Updated 1:40 a.m. ET with Juno orbit maneuver

After a nearly five-year journey, NASA's solar-powered Juno spacecraft achieved orbit around Jupiter on Monday night. Juno navigated a tricky maneuver — including slowing by around 1,212 mph — to insert itself into orbit in what NASA calls "the king of our solar system."

At 11:18 p.m. ET, Juno transmitted a radio signal to Earth that meant its main engine had switched on. It stayed on for 35 minutes, placing Juno into exactly the orbit that mission managers had planned for.
