Rebreather diving has gained popularity over the last few years. As you can imagine, these high tech dive units are not cheap. As with any large investment, buying your first rebreather can be daunting. Before you make the big purchase, it’s crucial that you dive and test out a variety of different models. But where do you start? How do you know what’s the best rebreather for your style of diving?

Though rebreathers all perform the same task: removing additional CO₂ from the breathing loop while adding the necessary amount of oxygen or nitrox – The way different models execute this task varies. Remember, a rebreather is a huge investment, and thus it’s important that you take the time to find the right machine for you and your type of diving.

One of our goals here at The Adventure Junkies is to make your life easier when it comes to gear shopping. In this guide, we’ll walk you through some things to consider before buying a rebreather and show you our selection of some of the best models out there.

The Pentagon is executing its first project under the authorities granted by the Defense Production Act in order to produce more than 39 million critical N95 masks amid the ongoing coronavirus pandemic.

“On the evening of April 10, the Department of Defense received approval from the White House Task Force to execute the first DPA Title 3 project responding to COVID-19,” Pentagon spokesman Lt. Col. Mike Andrews said in a statement.

“The $133M project will use these authorities to increase domestic production capacity of N95 masks to over 39 million in the next 90 days,” the statement added.

An astonishing number of viruses are circulating around the Earth’s atmosphere — and falling from it — according to new research from scientists in Canada, Spain and the U.S.

The study marks the first time scientists have quantified the viruses being swept up from the Earth’s surface into the free troposphere, that layer of atmosphere beyond Earth’s weather systems but below the stratosphere where jet airplanes fly. The viruses can be carried thousands of kilometres there before being deposited back onto the Earth’s surface.

“Every day, more than 800 million viruses are deposited per square metre above the planetary boundary layer — that’s 25 viruses for each person in Canada,” said University of British Columbia virologist Curtis Suttle, one of the senior authors of a paper in the International Society for Microbial Ecology Journal that outlines the findings.

The 15-year-old boy, a Yanomami from the village of Rehebe on the Uraricoera River, died Thursday, according to Brazil’s Ministry of Health.

He had been in the intensive care unit in Roraima General Hospital in Boa Vista, the capital of Roraima state, since April 3. The hospital has not revealed his cause of death, the Ministry of Health said.

Light only travels in straight lines, or does it? Scientists have known for centuries that light is composed of waves, but the fact that light can also act like a liquid, that is rippling and spiralling around obstacles like the current of a river, is a much more recent discovery that is increasingly an area of extensive research. However, as you’d expect the “liquid” properties of light only emerge under special conditions when the photons that make up the light waves are able to interact with one another.
