Not the most informative article, but it does have a map giving you an idea of how many of these facilities exist and in which countries. China is not the only place with labs.

Three of the 23 countries with BSL4 labs (Australia, Canada and the US) have national policies for oversight of dual-use research. At least three other countries (Germany, Switzerland and the UK) have some form of dual-use oversight, where, for instance, funding bodies require their grant recipients to review their research for dual-use implications.

Rising demand for BSL4 labs

That still leaves a large proportion of scientific research on coronaviruses carried out in countries with no oversight of dual-use research or gain-of-function experiments. This is particularly concerning as gain-of-function research with coronaviruses is likely to increase as scientists seek to better understand these viruses and to identify which viruses pose a higher risk of jumping from animals to humans or becoming transmissible between humans. More countries are expected to seek BSL4 labs, too, in the wake of the pandemic as part of a renewed emphasis on pandemic preparedness and response.

The World Health Organization classifies processed meat as a Group 1 carcinogen. Processed meat includes ham, sausage, bacon, pepperoni; they’re meats that have been preserved with salt or smoke, meat that has been cured, and meat treated with chemical preserves. Other Group 1 carcinogens include formaldehyde, tobacco, and UV radiation. Group 1 carcinogens have ‘enough evidence to conclude that it can cause cancer in humans.’

There is no question whether or not our current meat production complex is inhumane, unsanitary, or bad for the environment. Almost all chickens (99.9%), turkeys (99.8%), and most cows (70.4%) eaten in the United States are raised on factory farms. There are horrific consequences to this practice.

For example, the EPA estimates agriculture is the biggest contaminator of rivers and streams, to the point where feedlots, crop production, and manure runoff have led almost half (46%) of the U.S.’s rivers to be “in poor biological condition.”

Scientific American also explains, “TDM-approved feed containing antibiotics [are] a necessity if [factory farm animals] were to stay healthy in their crowded, manure-gilded home. Antibiotics also help farm animals grow faster on less food, so their use has long been a staple of industrial farming.” Many scientists worry that antibiotics used at such a scale on farms create unstoppable, drug-resistant bacteria that can transfer to humans; think inconveniences like nose infections or UTIs turned deadly because of the lack of antibiotics available to treat them.

The five-year survey, conducted across a section of the cosmos known as the nearby universe because of its proximity to our own galaxy, used the Atacama Large Millimeter/Submillimeter Array (ALMA) radio telescope located in Chile’s Atacama Desert. By conducting their survey in the radio part of the electromagnetic spectrum, rather than the optical part, the astronomers could focus on the faint glow from the dust and gas of the dark and dense molecular clouds, as opposed to the visible light from the young stars birthed by them.

This allowed the researchers to study how a star’s home cloud shapes its formation.

For those who track their diet, eating only the RDA for many nutrients may not optimize health. For example, the RDA for selenium is 55 micrograms per day, but is that amount optimal for reducing risk of death for all causes?

Inked fingerprints on paper forms. We’ve come a long way from the days when that was the height of forensic technology.

GE is light years ahead after launching a breakthrough portable DNA scanner at the 25th World Congress of the International Society for Forensic Genetics in Melbourne in early September.

The scanner uses a new process called microfluidics to present a DNA analysis and database match in only 85 minutes — a process that used to take at least 48 hours.

The way the team made the human–monkey embryo is similar to previous attempts at half-human chimeras.

Here’s how it goes. They used de-programmed, or “reverted,” human stem cells, called induced pluripotent stem cells (iPSCs). These cells often start from skin cells, and are chemically treated to revert to the stem cell stage, gaining back the superpower to grow into almost any type of cell: heart, lung, brain…you get the idea. The next step is preparing the monkey component, a fertilized and healthy monkey egg that develops for six days in a Petri dish. By this point, the embryo is ready for implantation into the uterus, which kicks off the whole development process.

This is where the chimera jab comes in. Using a tiny needle, the team injected each embryo with 25 human cells, and babied them for another day. “Until recently the experiment would have ended there,” wrote Drs. Hank Greely and Nita Farahany, two prominent bioethicists who wrote an accompanying expert take, but were not involved in the study.

The BREST-OD-300 reactor is planned to start operating in 2026. A fuel production facility will be built by 2023 and the construction of an irradiated fuel reprocessing module is scheduled to start by 2024, Rosatom said. The design of the lead-cooled reactor is based on the principles of so-called natural safety, which makes it possible to abandon the melt trap.

“The successful implementation of this project will allow our country to become the world’s first owner of the nuclear power technology which fully meets the principles of sustainable development in terms of environment, accessibility, reliability, and efficient use of resources,” said Rosatom’s Director General Alexey Likhachev. “Today, we reaffirm our reputation as a leader in world progress in the nuclear technologies, that offers humanity unique solutions aimed at improving people’s lives,” he added.

According to President of the Kurchatov Institute Mikhail Kovalchuk, the project is aimed at bringing nuclear power to a new level.
