For most of their lives, our hematopoietic stem cells (HSCs)—which produce all of our blood and immune cells—are quiet and inactive. But they also are the toughest cells in the blood system, able to survive exposure to levels of radiation or viral infections that kill most other blood cells.

A new study from researchers in Columbia’s Stem Cell Initiative has discovered how HSCs cheat death, which could lead to new therapies for blood cancers and other diseases related to aging and improve stem cell transplantation.

All hail the mushroom king :P.

It’s the fungus mushrooms are made of, but it can also produce everything from plastics to plant-based meat to a scaffolding for growing organs—and much more.

Female bedbugs who are ‘full bellied’ and therefore more attractive mates for males, are able to boost their immune systems in anticipation of catching sexually transmitted infections, research has found.

Led by the University of Sheffield, the research discovered a correlation between fed females and the chances of them being inseminated and therefore infected as a result.

To mitigate this, female bedbugs that have just dined on blood and are therefore full, are able to cleverly manage their simple immune system in anticipation of mating. This is in comparison to female bedbugs that do not get regular food, do not mate regularly and therefore do not have the same need to boost their immune system in defence of infection.

DARPA-funded chemists at the Massachusetts Institute of Technology (MIT) have devised a way to rapidly synthesize and screen millions of novel proteins that could be used as drugs against Ebola and other viruses. The team supports DARPA’s Fold F(x) synthetic chemistry program.

Certain plants, insects, crustaceans and fish possess the uncanny ability to change the sex of their offspring before they are born. Mammals have never before demonstrated this genetic skill, until now.

A new Tel Aviv University study reveals a genetic system in mammals that enables two animals to mate and produce only females. A similar system based on identical principles would produce only males.

Research for the breakthrough study was led by Prof. Udi Qimron, Dr. Ido Yosef and Dr. Motti Gerlic and conducted by Dr. Liat Edry-Botzer, Rea Globus, Inbar Shlomovitz and Prof. Ariel Munitz, all of the Department of Clinical Microbiology and Immunology at TAU’s Sackler School of Medicine. The research was published on July 1 in EMBO Reports.

The hospital technology, typically used to identify human ailments, captured perhaps the world’s smallest magnetic resonance image.

I’m super excited to share this new Quartz article of mine, part of an ongoing personal debate about #transhumanism, #kids, and #education in my family:

But the age of downloading experience and expertise directly into our brain mainframe is coming. So is downloading professional training, including everything from becoming a police officer to practicing medicine or investigative journalism.

For many in the audience, I think that was the first time considering this could become a reality in our lifetime.

Researchers at MIT in the US and DESY (Deutsches Elektronen-Synchrotron) in Germany have developed a technology that could shrink particle accelerators by a factor of 100 or more. The basic building block of the accelerator uses high-frequency electromagnetic waves and is just 1.5 cm (0.6 in) long and 1 mm (0.04 in) thick, with this drastic size reduction potentially benefitting the fields of medicine, materials science and particle physics, among others.
