Convention Countdown

The Republican National Convention is in 4 days in Cleveland.

The Democratic National Convention is in 11 days in Philadelphia.

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.

The Senate is set to approve a bill intended to change the way police and health care workers treat people struggling with opioid addictions.

My husband and I once took great pleasure in preparing meals from scratch. We made pizza dough and sauce. We baked bread. We churned ice cream.

Then we became parents.

Now there are some weeks when pre-chopped veggies and a rotisserie chicken are the only things between us and five nights of Chipotle.

Parents are busy. For some of us, figuring out how to get dinner on the table is a daily struggle. So I reached out to food experts, parents and nutritionists for help. Here is some of their (and my) best advice for making weeknight meals happen.

"O Canada," the national anthem of our neighbors up north, comes in two official versions — English and French. They share a melody, but differ in meaning.

Let the record show: neither version of those lyrics contains the phrase "all lives matter."

But at the 2016 All-Star Game, the song got an unexpected edit.

At Petco Park in San Diego, one member of the Canadian singing group The Tenors — by himself, according to the other members of the group — revised the anthem.

School's out, and a lot of parents are getting through the long summer days with extra helpings of digital devices.

How should we feel about that?

Police in Baton Rouge say they have arrested three people who stole guns with the goal of killing police officers. They are still looking for a fourth suspect in the alleged plot, NPR's Greg Allen reports.

"Police say the thefts were at a Baton Rouge pawn shop early Saturday morning," Greg says. "One person was arrested at the scene. Since then, two others have been arrested and six of the eight stolen handguns have been recovered. Police are still looking for one other man."

A 13-year-old boy is among those arrested, Greg says.

After an international tribunal invalidated Beijing's claims to the South China Sea, Chinese authorities have declared in no uncertain terms that they will be ignoring the ruling.

The Philippines brought the case to the Permanent Court of Arbitration in The Hague, objecting to China's claims to maritime rights in the disputed waters. The tribunal agreed that China had no legal authority to claim the waters and was infringing on the sovereign rights of the Philippines.

Donald Trump is firing back at Supreme Court Justice Ruth Bader Ginsburg after she disparaged him in several media interviews. He tweeted late Tuesday that she "has embarrassed all" with her "very dumb political statements" about the candidate. Trump ended his tweet with "Her mind is shot - resign!":

Tiny Bubbles: Injectable Oxygen Foam Tested For Emergency Care

Sep 19, 2012
Originally published on September 19, 2012 4:12 pm

A lot of medicine's direst emergencies come down to one problem: lack of oxygen.

Cardiologist John Kheir started thinking about that when a little girl in his care, drowning from lung hemorrhages, died before she could be hooked up to a heart-lung machine that would have kept her blood oxygenated while the damage was repaired.

That was in 2006. Now Kheir and his colleagues at Children's Hospital in Boston think they've figured out a way to inject oxygen directly into the bloodstream — a route that could save the lives of many patients who can't get enough oxygen, fast enough, through their airways.

Currently, injecting oxygen (or any gas) directly into the bloodstream is a big no-no, because it can form a large bubble called an embolism — an obstruction that can be fatal.

The new method — not yet tried in humans — encapsulates pure oxygen in microbubbles made of fat molecules. "It's a foam a lot like shaving cream," Kheir told Shots. "The purpose is to carry oxygen gas in an injectable way."

The bubbles release the oxygen in milliseconds in oxygen-starved tissues. That happens because of the natural affinity of hemoglobin, the business molecule within red blood cells, for oxygen. If there's any oxygen in the vicinity, hemoglobin immediately soaks it up.

Kheir says his injectable oxygen foam could buy crucial time in a number of medical scenarios, such as:

  • On ambulances, when there's a need to deliver oxygen as fast as possible to a patient during cardiac arrest, an asthma attack, a near-drowning episode or other catastrophes.
  • On the battlefield, when it can be difficult to insert a breathing tube into the airway of an injured soldier in hemorrhagic shock.
  • In the intensive care unit, when conventional oxygen delivery through a mask is compromised by lung injury or disease, severe asthma, obesity or convoluted airways.

"This would help us stabilize patients for a few minutes, and that could be immensely valuable," Kheir says.

So far the injectable oxygen has been tested only in rabbits with experimentally blocked windpipes. The researchers have been able to keep rabbits alive for up to 15 minutes without a single breath. All but one of the animals that got the oxygen foam avoided the cardiac arrest that follows oxygen deprivation within 8 to 10 minutes.

The next step is to give the oxygen injections to healthy volunteers to test its safety. Then comes the difficult part — identifying those patients who could be given the oxygen foam during real-life instances of oxygen deprivation.

"That's a complicated question," Kheir says, "because we really want to have a patient population we can not only study effectively but who can consent ahead of time, and these are emergency situations."

The research has been funded up to now by a $1.5 million grant from the Department of Defense. The work is described in a paper published in Science Translational Medicine.
