Chinese Scientists Try to Cure One Man's HIV With Crispr

He would be eligible to participate in the first-ever clinical trial to assess the safety of trying to cure both the cancer and the infection in a single procedure using the gene-editing tool called Crispr .In July of 2017, doctors in Beijing blasted the patient with chemicals and radiation to wipe out his bone marrow, making space for millions of stem cells they then pumped into his body through an IV.

The Bizarre, Peaty Science of Arctic Wildfires

The Bizarre, Peaty Science of Arctic Wildfires

That, though, would require forest management across swaths of the Arctic, a kind of management we in the US can’t even do right on a small scale .What we’re looking at, then, is yet another complicating factor in the massive complexity that is climate change: When peat burns, it emits lots of CO2, and when peatlands aren’t healthy, they don’t capture any.

Gulf Fisheries Are Under Siege—Now Comes Tropical Storm Barry

Gulf Fisheries Are Under Siege—Now Comes Tropical Storm Barry

A historic slow-moving flood of polluted Mississippi River water loaded with chemicals, pesticides, and human waste from 31 states and two Canadian provinces is draining straight into the marshes and bayous of the Gulf of Mexico —the nurseries of Arnesen’s fishing grounds—upsetting the delicate balance of salinity and destroying the fragile ecosystem in the process.

How Remote Lakes Could Help Unravel the Mysteries of Microplastic

How Remote Lakes Could Help Unravel the Mysteries of Microplastic

The International Institute for Sustainable Development’s Experimental Lakes Area, or ELA, are testing grounds that allow researchers to isolate a pocket of water within a lake and add pollutants like hormones and flame retardants—and now potentially microplastics—and watch how the ecosystem responds.

YouTube Testimonials Lure Patients to Shady Stem Cell Clinics

YouTube Testimonials Lure Patients to Shady Stem Cell Clinics

Then there’s the ease with which stem cell clinics reach potential patients online. Often, this involves the patient testimonial video—one of the most successful marketing strategies employed by stem cell clinics.

An IOS App That Secretly Spies on You, And More News

Say hello to your new speaker-lamp. A cervix-navigating robot could save the rhinos. To be fair, these rhinos will need a lot more than a cervix-navigating robot to survive.

How to Keep Parents From Fleeing STEM Careers

How to Keep Parents From Fleeing STEM Careers

“For professionals like these it typically costs the company between 1 to 1.5 times their annual salary to be able to replace that person and train a new person.” At that point, she argues it is far more cost-effective for companies to pay for policies that would support these families, things like paid family leave, flexible work hours, and subsidized child care.

Drones Drop Poison Bombs to Fight One Island’s Rat Invasion

Drones Drop Poison Bombs to Fight One Island’s Rat Invasion

On Seymour Norte, officials and conservationists are once again banishing the rats, but the war against invasive species for the purity of the world’s islands has only just begun. Fighting invasive species demands constant vigilance, as the return of rats to Seymour Norte shows.

For Brown Bears and Salmon, It’s Not Just About Numbers

For Brown Bears and Salmon, It’s Not Just About Numbers

Looking at streams on Alaska’s Kodiak Island, the researchers found that the varied timing of salmon migrations likely matters as much as abundance. Previous research found that this variance in migration timing among streams matters a lot to brown bears and other wildlife that feed on salmon.

Aquaculture Could Be Conservation’s Secret Weapon

Aquaculture Could Be Conservation’s Secret Weapon

“But we could use aquaculture to replace some of those water filtration benefits, and at the same time grow food.” In places where excess nutrients are a problem, like the Chesapeake Bay, shellfish aquaculture could even help offset the negative environmental impacts of other industries.

We Know Exactly How to Stop Wildfires—With Money

We Know Exactly How to Stop Wildfires—With Money

Except if you don’t reduce the number of trees, and if you then also try to put out every fire, and allow runaway climate change to make droughts and heat waves worse … the boreal forests of North America will continue to literally go up in smoke, erasing the landscape and spewing climate-changing carbon into the atmosphere.Everyone pretty much agrees on how to deal with our new Burning World: Stop trying to suppress fire and start managing that land to restore a more natural (less intense) fire regime.

Hundreds of Seals Are Dying on the New England Coast

Hundreds of Seals Are Dying on the New England Coast

5.Marine Mammals of MaineIt is theoretically possible though unlikely for viruses to jump species, Dr. Goldstein noted, and dogs have been known to give distemper to seals, though the opposite has not been seen.[To report a stranded or dead seal, call 866-755-NOAA.]“It’s hard when you see people intervene with animals that are not doing well,” said Ms. Doughty, whose team has responded to more than 400 stranded animals over the last month, including 30 on Sept.

Arctic carbon cycle is speeding up – Climate Change: Vital Signs of the Planet

Arctic carbon cycle is speeding up – Climate Change: Vital Signs of the Planet

A new NASA-led study using data from the Arctic Boreal Vulnerability Experiment (ABoVE) shows that carbon in Alaska's North Slope tundra ecosystems spends about 13 percent less time locked in frozen soil than it did 40 years ago.

To Heal Wounds, Cells Time-Travel Back to a Fetal State

To Heal Wounds, Cells Time-Travel Back to a Fetal State

Instead, the cells of the damaged tissue turn the clock back all the way to a more fetal state, tapping into the proliferative power that once characterized development — and a program thought to have long gone silent.Atom Bombs and Self-Renewing CellsIn the early 1900s, scientists theorized that the specific blood cell types they’d learned to distinguish from one another under a microscope — red blood cells, white blood cells and platelets — came from a common, more primitive source: a stem cell.

An Adorable Rodent Gives a Glimpse Into Earth’s Climate Chaos

While barn owls and western meadowlarks were “losers” during the drought, killdeer and greater roadrunners were “winners.” The blunt-nosed leopard lizard suffered; the side-blotched lizard came up in the world.“The drought kind of knocked down the species that were dominating and allowed the underdogs to do better and stay in the system,” says wildlife ecologist Laura Prugh of the University of Washington, lead author on the new paper in Nature Climate Change.For all the winners and losers, nearly three quarters of species weren’t strongly affected by the drought.

New Science Shows Nature’s Potential to Fight Climate Change

Building on a large body of existing research, they divided natural carbon sinks into 20 different pathways and then calculated both their potential for emissions reductions and the associated costs.
