Nitric oxide may help prevent kidney issues after heart surgery

Nitric oxide may help prevent kidney issues after heart surgery

Health
June 20 (UPI) -- A randomized, controlled trial in China recently found that patients who inhaled nitric oxide during and for 24 hours after heart surgery saw a decreased risk of developing acute and chronic kidney problems. The study, published in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine, is the first to show a drug could reduce kidney injury resulting from heart surgery, the researchers say. Previous studies have shown that prolonged cardiopulmonary bypass can disrupt circulating red blood cells and the release of hemoglobin, which can cause acute kidney injury that leads to kidney failure and the need for long-term hemodialysis. While several drugs have been tested to prevent kidney problems after surgery, this is the first one that ac...

Unique microbe could thrive on Mars, help future manned missions

Science
June 18 (UPI) -- New research suggests certain cyanobacteria could thrive on Mars. The microbes could even be used to provide future space colonies with oxygen. "This might sound like science fiction, but space agencies and private companies around the world are actively trying to turn this aspiration into reality in the not-too-distant future," Elmars Krausz, chemistry professor at Australian National University, said in a news release. "Photosynthesis could theoretically be harnessed with these types of organisms to create air for humans to breathe on Mars." Cyanobacteria are the only photosynthetic prokaryotes capable of producing oxygen. They're the most abundant ground of bacteria on the planet and have colonized Earth since as early as 2.5 billion years ago. Several cyanobacteria h...
Nanorobots help remove bacteria, toxins from blood

Nanorobots help remove bacteria, toxins from blood

Health
May 31 (UPI) -- Nanorobots that are about 25 times smaller than the width of a human hair have been developed to remove harmful bacteria and toxins by swimming through the bloodstream. Engineers at the University of California San Diego hope one day their proof-of-concept method will offer a safe and efficient way to detoxify and decontaminate biological fluids. Their findings were published Wednesday in the journal Science Robotics. "The idea is to create multifunctional nanorobots that can perform as many different tasks at once," co-first author Berta Esteban-Fernandez de Avila, a postdoctoral scholar at UC San Diego, said in a press release. "Combining platelet and red blood cell membranes into each nanorobot coating is synergistic -- platelets target bacteria, while red blood cells ...

The government created a fake cryptocurrency to help you avoid scams

Finance
What is an ICO? There's a hot new crypto coin linked with luxury travel out there: HoweyCoins. But this initial coin offering isn't going to earn you anything more than a better understanding of how crypto works and a warning about scams. This mock ICO — or initial coin offering — is a creation of the Securities and Exchange Commission's office of investor education and advocacy in an effort to teach people about the dangers and pitfalls of investing in cryptocurrencies. Lesson one: If it sounds too good to be true, it probably is. The goal of the project is to acquaint investing novices with signs of fraud before it's too late. "The rapid growth of the 'ICO' market, and its widespread promotion as a new investment opportunity, has provided fertile gro...

Realmuto, Straily help Marlins end losing streak vs. Braves

Sports
May 11 (UPI) -- Miami Marlins catcher J.T. Realmuto was a triple short of the cycle in a 6-3 win against the Atlanta Braves Friday at Marlins Park in Miami, Fla. Realmuto's 3-for-5 effort included a single, double and home run. He had two RBIs and scored twice out of the leadoff spot. He also backed up a strong starting outing by Marlins righty Dan Straily, who earned his first victory of the season. "Every time I gave up a run, we scored sometimes the next pitch," Straily said. It was really nice to go up there and have that kind of run support. Just knowing that I have to keep us right there. Just keep going. The goal is a zero every single inning. You just got to keep going. These guys just kept going tonight. They just kept putting together quality at-bat after quality at-bat." The w...
