Live from NPR News, I'm Lakshmi Singh. NPR has learned that White House Chief of Staff Susie Wells plans to convene a security meeting at the White House to reassess security protocol for the president and others following Saturday night's shooting outside the White House Correspondent's Dinner at the Washington Hilton. A White House official not authorized to speak publicly says the gathering will include the White House operations team, Secret Service and Department of Homeland Security leadership. They'll explore additional security options, possibly as President Trump prepares to take part in events marking the 250th anniversary of American independence. Well, the president's praising the response of the Secret Service and law enforcement, but NPR's Tamara Keith tells us he's also back to criticizing the press and Democrats.

In the hours after the dinner, Trump hit a note of unity. The then Sunday, in an interview with 60 Minutes, he was asked about political violence in America and what he as president can do to change the trajectory in the country.

It's always been there. People are assassinated, people are injured, people are hurt. And I'm not sure that there's any more now than there was. I do think that the hate speech of the Democrats, much more so, is very dangerous. I really think it's very dangerous for the country.

Of the alleged attacker, Trump said he was radicalized and, quote, probably a pretty sick guy. Tamara Keith, NPR News.

The suspect is due to be arraigned this afternoon. Well, 36 hours after the shooting, the head of the British monarchy is making a historic state visit to the United States. President Trump and first lady Melania Trump are set to welcome King Charles and Queen Camilla at the White House this afternoon. Iran's foreign minister held meetings in Russia today after he made stops in Pakistan and Oman. But there's still no indication Iran and the United States will sit down for another round of peace talks soon. Here's NPR's Aba Tarawi.

Iran is coming under pressure from its regional neighbors and allies to open the Strait of Hormuz, which it now controls. China and neighbors Saudi Arabia and Qatar are pushing for oil and gas to be allowed to flow through the waterway again. Iran's also facing the consequences of the US Naval blockade on its ports. President Trump told FOX News on Sunday Iran has just three days of storage left before its oil pipelines explode from pressure since it's running out of ships to store it on. Amina Bucker, head of Mideast Energy at research firm Kepler, says Iran has closer to 20 days of storage left.

But usually what happens is that before they run out of storage they begin

to, like, slowly cut production.

And she says Iran has a southern oil terminal it could use if ships bypass that U.S. blockade. Aya Baltrari, NPR News, Dubai.

U.S. stocks are trading lower this hour. The Dow is down more than 100 points. From Washington, this is NPR News. Colorectal cancer is now the most lethal among young adults. Part of the challenge is people who are young are least likely to discuss their bowel functions. Sanpr Zuki Noguchi has more.

Dr. Neal Parikh at Hartford Hospital in Connecticut noticed something about human behavior.

So we love talking about pooping until about the age of 12. And then there's this radio silence.

He says this demographic's discomfort with bodily functions is a reason many don't mention seeing blood or other changes in their stool.

We need to normalize this so it comes up at dinner table.

That, he says, would save lives by getting more people to seek screenings or diagnostic tests. Yuki Noguchi, NPR News.

Let's talk seeds. Researchers say they have found the first direct evidence that seeds do sense sound in nature, and it may help them grow. Here's NPR's Amy Held.

As those who sing to their plants may suspect they really can pick up on sound, MIT engineers experimented with rice seeds in water, finding those exposed to rain sound germinated 30 to 40% faster than others in identical conditions with no drips, whether in water or on the ground, raindrops generate a sound wave that vibration researchers hypothesize, could shake seeds out of a dormant state, stimulating them to germinate, putting rain sensing seeds at an advantage. Those close enough to the surface to respond may also be at the best depth to take in the moisture and grow. The findings are published in the journal Scientific Reports. Amy Held, NPR News.
