Vaping can clog your lungs

E-cigarettes have been marketed as being safer than smoking tobacco but that doesn’t mean that they’re safe.

A multi-university study published in June in the American Journal of Respiratory and Critical Care Medicine reports that vaping – smoking e-cigarettes – dries out the airways in the lungs, making it harder for smokers to clear mucus from the passages. Vaping also dries the mucus itself, making it stickier and harder to get rid of.

When mucus can’t be cleared, the lungs are more susceptible to infection or damage.

Anti-heartburn drugs found to cause kidney disease, cancer

Nexium, Prilosec and other so-called “proton-pump inhibitor” anti-heartburn drugs, or PPIs, do more than tame that chili dog you had for lunch. Long-term use can cause cardiovascular disease, kidney disease, and cancer in the upper digestive tract, according to a study from Washington University’s medical school.

The study looked at about 210,000 US military veterans and was able to correlate specific illnesses and causes of death to these drugs after weeding out other potential factors.

Cells found that regenerate body parts

Cells that control the regeneration of body parts have been found in tadpoles but scientists think the discovery holds promise for finding a mechanism to do the same in mammals – including people.

A tadpole will grow a new tail if it loses the original but no one has known how. Now researchers at the University of Cambridge have isolated what they call “regeneration-organizing cells” that spark stem cells to grow into a new tail.

Harvesting metals from the deep ocean floor

The treasures that litter the world’s seabeds aren’t in pirates’ chests; they’re in fist-sized lumps of ore that are rich in minerals and metals such as cobalt, a key component in electronic devices, as well as copper, molybdenum, nickel, and others.

But a lack of workable technology, coupled with the relative abundance of these minerals topside, has kept those treasure-laden nodules down deep.

Drinking the bottle along with the water

People in North America ingest at least 100,000 tiny pieces of plastic every year, according to a report by a coalition of research biologists in British Columbia. The pieces may be as long as a fifth of an inch – about five millimeters – and thin enough to be virtually invisible.

The report is the first that attempts to quantify the amount of plastic routinely entering our bodies.

The human heart in 3d

Researchers at Tel Aviv University have 3D-printed a complete, small-scale human heart, complete with inner chambers and its own blood vessels and circulatory system.

Just as impressive, the heart matches the biochemical and immune system properties of the person who donated the cells the heart was made from. That means that, if the heart were implanted in the cells’ donor, the body would recognize it and not reject it as alien.

Brain loss, brain gain…

Alzheimer’s disease kills more people in the U.S. than breast cancer and prostate cancer combined. It’s now the number one killer in England and Wales. There’s a new case in the world every three seconds.

And while there are no treatments that can reverse or even stop its progression, recent research has shown that certain protocols, mostly lifestyle related, can improve symptoms, slow down the rate of neurological decline, and help prevent the disease from taking over in the first place.
