The push for renewable energy in the U.S. often focuses on well-established sources of electricity: solar, wind and hydropower. Off the coast of California, a team of researchers is working on what they hope will become an energy source of the future — macroalgae, otherwise known as kelp.

If you're a woman, there's a good chance you've used Johnson's Baby Powder at some point. It smells good, and it can keep you dry.

But is it dangerous?

Dr. Daniel Cramer says yes. He's a professor of obstetrics and gynecology at Brigham and Women's Hospital in Boston. He says talc — the mineral in talcum powder — can cause ovarian cancer.

"Overall, women may increase their risk in general by about 33 percent by using talc in their hygiene," Cramer says.

Brent Deppe is taking me on a tour of the farm supply business, called Key Cooperative, that he helps to manage in Grinnell, Iowa. We step though the back door of one warehouse, and our view of the sky is blocked by a gigantic round storage tank, painted white.

"This is the liquid nitrogen tank," Deppe explains. "It's a million-and-a-half gallon tank."

Nitrogen is the essential ingredient for growing corn and most other crops. Farmers around here spread it on their fields by the truckload.

What if I told you there was a way to use technology to save an estimated $100 billion to $300 billion dollars a year in health care spending in the U.S.? That's the estimated cost incurred because people don't take the medications they're prescribed.

Before a solar project, Mark Holohan usually gives his customers plenty of time to mull over the cost. But lately, installers are scooping up panels so quickly that Holohan has trouble guaranteeing a price for too long.

"We have a sort of panic buying mode in the marketplace right now. Inventories have fallen. Availability has decreased. Prices have risen," Holohan, the solar division manager at Wilson Electric, said over the clatter of machines and workers in the company's warehouse outside Phoenix, Ariz.

The list of charities and nonprofits that have canceled fundraising events at Mar-a-Lago continues to grow. At least 20 groups now have pulled out of galas that had been scheduled for President Trump's country club in Palm Beach, Fla.

In announcing the cancellations, many of the groups cited the controversy surrounding Trump's recent comments that "both sides were to blame" for the violence that occurred during a white supremacists' rally in Charlottesville, Va.

The Environmental Defense Fund opened an office near Walmart's headquarters in Bentonville, Ark., 10 years ago. It was part of a carefully plotted strategy to persuade the giant retailer that going green could be good for business. If it worked, it certainly could be good for the planet — Walmart's revenues are bigger than the entire economy of most countries.

"We really saw that working with companies could be transformative at a scale that was pretty unmatched," says Suzy Friedman, a senior director at EDF.

Classic car shows are a summer tradition. But if you want the most exotic, rare, and the most expensive cars in the world, then you need to head to the Monterey Peninsula, Calif. The 67th annual Pebble Beach Concours d'Elegance caps off a week of intensive, obsessive car love.

The Concours this year features 204 of the highest-caliber cars that have ever been made. Essentially, the international car world descends on the region. Fifteen countries and 31 states enter the elite car show held on the famed 18^th hole of the Pebble Beach golf course.

On Friday, three well-known charities — the American Red Cross, the Salvation Army and Susan G. Komen — announced they are canceling plans for fundraising events at President Trump's Palm Beach country club, Mar-a-Lago.

The three joined a growing list of nonprofits that have severed ties with the exclusive, Trump-owned resort. Others include the Cleveland Clinic and the American Cancer Society.

In 2011, the National Park Service put in place a policy to encourage national parks to end the sale of bottled water. The aim was to cut back on plastic litter.

It was not actually an outright ban — but 23 out of 417 national parks, including Grand Canyon National Park and Zion National Park, implemented restrictions on bottled water sales. The parks encourage visitors to use tap water and refillable bottles instead.

Now, The Trump administration has reversed this Obama-era policy.

Worried about Internet companies snooping on your online browsing? You might turn to something called a virtual private network to protect your privacy. But researchers say these networks can themselves be insecure.

Earlier this year, the federal government rolled back rules that would have prevented Internet service providers from tracking your activity online.

Until now, Ed Butowsky has enjoyed edging close to the limelight — an investment adviser who has pursued celebrity clients, his profile burnished through appearances on Fox News and its sister channel Fox Business Network.

Butowsky, a 55-year-old former Morgan Stanley executive, has been celebrated in glossy magazines, touted for his financial acumen, toasted for his proximity to the powerful.

In recent weeks, however, Butowsky has received unwanted scrutiny.

President Trump declared Wednesday he is disbanding two economic advisory panels, after a growing number of the corporate CEO's who sat on them decided to leave, in the wake of Trump's response to the violence in Charlottesville, Va., over the weekend.

Trump said in a tweet that he is ending the Manufacturing Jobs Initiative and the Strategic and Policy Forum "rather than putting pressure on the businesspeople" that made up those groups.

Officials from the U.S., Mexico and Canada met Wednesday to begin renegotiations of the North American Free Trade Agreement. In an opening statement, U.S. Trade Representative Robert Lighthizer praised President Trump for the fact that these negotiations were even happening.

"American politicians have been promising to renegotiate NAFTA for years, but today, President Trump is going to fulfill those promises," he said.

President Trump roiled opinion Tuesday by reversing himself and reiterating his claim that "both sides" of a white supremacist rally in Charlottesville, Va., were to blame for violence that killed one woman and left many injured.

Trump made the remarks at a news conference at Trump Tower in New York, engaging in back-and-forth exchanges with reporters about what transpired in Charlottesville over the weekend.

At age 31, Nixon Arias cut a profile similar to many unauthorized immigrants in the United States. A native of Honduras, he had been in the country for more than a decade and had worked off and on for a landscaping company for nine years. The money he earned went to building a future for his family in Pensacola, Fla. His Facebook page was filled with photos of fishing and other moments with his three boys, ages 3, 7 and 8.

But in November 2013, that life began to unravel.
