Plankton Are Multiplying Like Crazy Due to Warming

The population of a microscopic marine alga in the north Atlantic Ocean apparently is booming due to climate change, but scientists — who’ve been caught off-guard by the development — aren’t sure what it means for the aquatic environment. Details

Antibiotic resistance is one of the biggest threats to global health today.

It is compromising our ability to treat infectious diseases and undermining many advances in health and medicine. This can affect anyone in any country, and is not just a problem for regular antibiotic users. 

Look at the causes and tips provided by the World Health Organization (WHO) to find out what you can do.

The Fantastically Strange Origin of Most Coal on Earth

The absence of the tiniest creature can shape the world in the biggest way.

Ever wonder how coal formed?

Forests For All Forever

From tissue and paper, to packaging, furniture and building materials, people consume and depend on forest products every day.

We often take our surroundings for granted. This is an excellent piece that outlines some of the problems and proposes a cool way to keep our forests going. 

In the San Joaquin Valley, a legacy of shortsighted land-use planning has intensified the water crisis for poor residents.

Arctic Warming Produces Mosquito Swarms Large Enough to Kill Baby Caribou

Lauren Culler's study in Proceedings of the Royal Society B found that Arctic warming is producing larger and larger mosquito swarms, which can kill caribou.

Apparently, because of the earlier thawing of the permafrost, and the increasing amount of permafrost that is melting each, each because of climate change, the Alaska state bird, aka the mosquito, is swarming in unprecedented numbers. The article tells us that mosquitos can kill a baby caribou calf by draining its blood, because the calf is already weakened by the scarcity of food sources also attributable to climate change.

Here’s a video, showing mosquitos swarming in Alaska and annoying a baby owl and a herd of caribou.

Check out these photos, taken by scientists in Alaska. If mosquitos make you squirm, close your eyes:

Ending slavery will also help save the one thing that connects us all... Earth.

“Desperate migrants from Myanmar and Cambodia are enslaved on fishing boats to strip the oceans of fish… in Brazil, young men are trapped by debt in work illegally logging the Amazon forest… Brick kilns in India, operated by bonded labourers, are fuelled with old tyres and used motor oil, spewing carcinogens into the air.”

Brain, Bone and Blood Vessels Coming Hot Off the Press

Could the days of custom clavicles and bespoke bladders produced just in the knick of time for suffering patients be around the corner?

While keeping an eye on tissue engineering studies, we’ve been seeing some significant wins in the lab that are bringing the sci-fi future of on-demand 3-D printed organs, bone and blood vessels closer. 

Harvard and Brown bioengineers are taking their own routes to build complex tissues in customized 3-D printers. And just the other week, we reported on newly unveiled work at the University of Florida to print complex soft structures in baths that could one day birth replacement human parts along with soft robots.

Now, Carnegie Mellon engineers reported on Friday that they had successfully printed simplified proof-of-concept anatomical structures like mini femurs, blood vessels and brains suspended in soft gelatin. Learn more and see a video below.

Earth Could Lose a Third of Its Topsoil

You might think that dirt doesn’t matter that much — after all there seems to be so much of it all over the planet.

But researchers warn that the world’s precious supply of topsoil — which we need to grow food crops, absorb excess carbon and supply us with new antibiotics — is being lost faster than it can be replenished through natural processes. And the decreasing supply of soil could have a catastrophic effect on agriculture and the world supply of food.

The UN, which designated 2015 as the International Year of Soils, warns that 33 percent of the planet’s soil resources are being degraded due to erosion, pollution, acidification and nutrient depletion — destructive processes that are caused by bad land management. And unless new approaches are adopted, the amount of productive farmland on Earth per person will only amount to one-fourth of the amount available in 1960.

In December, the UN is set to release a report on the state of the world’s soil, and it’s likely to present an even more grim picture, according to a preview in New Scientist. We’re losing soil at the rate of 30 soccer fields per minute, and if we don’t slow the decline, the planet’s entire supply of soil for farming could be gone by 2075.
