Fifty-nine labs around world handle the deadliest pathogens – only a quarter score high on safety

Posted by in category: biotech/medical

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

Vegans Diets and Longevity: What Existing Science Actually Says

Posted by in categories: biotech/medical, chemistry, life extension, science

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.”

Selenium: How Much Is Optimal For Health?

Posted by in categories: biotech/medical, food, life extension

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?

DNA scanning in the palm of your hand

Posted by in categories: biotech/medical, genetics

Circa 2013 o.,.o.


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.

Scientists Grew Human Cells in Monkey Embryos, and Yes, Its an Ethical Minefield

Posted by in categories: bioengineering, biotech/medical, chemistry, ethics, neuroscience

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.

New record distance for quantum communications

Posted by in categories: biotech/medical, computing, government, internet, quantum physics

Toshiba’s Cambridge Research Laboratory has achieved quantum communications over optical fibres exceeding 600 km in length, three times further than the previous world record distance.

The breakthrough will enable long distance, quantum-secured information transfer between metropolitan areas and is a major advance towards building a future Quantum Internet.

The term “Quantum Internet” describes a global network of quantum computers, connected by long distance quantum communication links. This technology will improve the current Internet by offering several major benefits – such as the ultra-fast solving of complex optimisation problems in the cloud, a more accurate global timing system, and ultra-secure communications. Personal data, medical records, bank details, and other information will be physically impossible to intercept by hackers. Several large government initiatives to build a Quantum Internet have been announced in China, the EU and the USA.

Does Telomere Length Really Affect Lifespan?

Posted by in categories: biotech/medical, genetics, life extension

What Are Telomeres?

As our cells divide (a process known as mitosis), our cells replicate the long strands of DNA located within the nucleus of our cells (known as chromosomes). This process however is imperfect, and due to the mechanics of how this is carried out by the body, the DNA is shorted ever so slightly during each replication cycle. I will not get into the details on how exactly this happens in this article, but if you are interested then this video should give you a better understanding of this process. In order to prevent important parts of the DNA being lost through the replication process, areas of what is mostly blank DNA at the end of the chromosomes are used as a sort of sacrificial buffer, allowing for the DNA to be replicated without the loss of genetic information. These areas of the chromosomes are known as telomeres. In addition to providing a buffer zone for DNA replication, telomeres also prevent broken strands of DNA attaching themselves to the ends of chromosomes, which both prevents chromosomes from becoming conjoined, as well as allowing for the opportunity for the broken strand of DNA to be repaired.

Deposits of Copper And Magnetic Iron Found in Alzheimers Patients Brains

Posted by in categories: biotech/medical, neuroscience

High levels of labile iron have been linked to neurodegenerative disorders like Alzheimer’s before. Similarly, copper is another mineral typically shielded safely in a protein, yet thoroughly capable of making a mess of our brains in labile form.


Set aside every scrap of iron inside a human body and you might have enough to fashion a nail or two. As for copper, you’d be lucky to extract just enough to make a small earring.

Scarce as they are, these two metals are necessary for our survival, playing essential roles in human growth and metabolism. But one place we wouldn’t expect to find either is clumped inside our brain cells.
