Low-grade methane leaks are bad for business (that gas could be heating up a home) and bad for the environment (it traps heat up in the atmosphere). Because a methane spill is invisible and has no smell — unless there's about to be an explosion (and if so, run!) — it can be hard to track one down.

That's where a tricked-out Google Street View car comes into play. Google Earth Outreach and the Environmental Defense Fund have teamed up to turn several Subaru Imprezas into mobile methane trackers. As Bloomberg reports, scientists add tubing across the front grill, which helps push a constant stream through a very small dehumidifier and then into a gas analyzer. Real-time data is streamed to a monitor, showing how fast the car is driving and the amount of methane on the street.

The pilot project's results were released on Wednesday, with information coming in from Boston, Indianapolis, and Staten Island. The findings seem to show that older cities have more of an issue with leaks, likely due to old infrastructures. Indianapolis, which has newer pipes, was the cleanest, with just one leak recorded for every 200 miles.

Those involved in the project are excited to use the information as a way of influencing how cities plan in the future. "This is the beginning of what I really see as a big shift in the way we can give people data about the environments they live in," Steven Hamburg, chief scientist for the EDF, told Bloomberg.

Princess Charlotte, the daughter of Prince William and Kate Middleton, is set to turn 1 on Monday. What would a royal birthday be without some formal photos to celebrate? Kensington Palace shared a few gems of the tyke Sunday:

Nice camera work, Kate.

Could she be any cuter?

Democratic presidential hopeful Bernie Sanders raised $25.8 million in April, the campaign said Sunday. That's a sharp drop from the $44 million he pulled in in March.

The campaign put a positive spin on the news, noting it surpasses the campaign's monthly average of $17 million.

Malia Obama will attend Harvard University in 2017 after taking a gap year, President Obama and First Lady Michelle Obama announced Sunday. The decision to take a year off will theoretically lessen the spotlight in college, as her father will be out of office well before she starts classes.

Harvard's acceptance rate this year was just 5.2 percent, the lowest in the institution's history, The New York Times reports. Obama will join a storied club of presidential children that have attended Harvard as undergraduate or graduate students, which includes figures ranging from Robert Lincoln to George W. Bush.

In April, Democratic presidential frontrunner Hillary Clinton and New York City Mayor Bill de Blasio (D) made a seriously uncomfortable joke at a comedy show.

Here's a quick refresher: De Blasio, joking about his chronic lateness, said he was running on "CP Time." Colored People's Time has long been a reference to the racist stereotype that black people are frequently late. Clinton jumped in, jokingly claiming the acronym really means "Cautious Politician Time."

President Obama took Clinton and de Blasio to task Saturday during his speech at the White House Correspondents' Dinner. He apologized for being late and said he was running on CPT, which stands for "Jokes That White People Should Not Make." Watch the zinger below. Julie Kliegman

Rev. Daniel Berrigan, a Jesuit priest influential in forming U.S. opposition to the Vietnam War, died Saturday at age 94, The New York Times reports.

In 1968, Berrigan and his brother led other activists in seizing hundreds of local draft records in Catonsville, Maryland, and setting them on fire with homemade napalm. Berrigan was imprisoned. His activism and subsequent arrests continued in his later years.

"The day after I'm embalmed, that's when I'll give it up," he said in 2001. Julie Kliegman

Donald Trump leads the Republican presidential race in Indiana with 49 percent support among likely voters, according to a Wall Street Journal/NBC News/Marist poll out Sunday.

Ted Cruz sits 15 percentage points behind, with 34 percent support, and John Kasich notched just 13 percent. The margin of error is 3.9 percentage points.

On the Democratic side, Hillary Clinton holds a narrow lead over Bernie Sanders, 50 percent to 46 percent, ahead of Tuesday's primaries. That's smaller than the poll's 4.6-point margin of error. Julie Kliegman

Sen. Ted Cruz (R-Texas) picked up about 80 delegates of more than 170 on the table at local and state conventions Saturday, Politico reports.

He snagged a majority of delegates in Arizona and Virginia, two states that strongly backed Donald Trump in primaries. Cruz also made gains in Missouri. Trump fared well in Massachusetts, Alaska, and Arkansas.

Most delegates are obligated to support the winner of their state's nominating contest on the Republican National Convention's first ballot, but can switch allegiances in future rounds of voting. Cruz's strategy banks on Trump not being able to grab the minimum of 1,237 delegates needed to secure the party's nomination outright. Julie Kliegman
