A critical component of healthcare, blood transfusions play a vital role in saving lives around the globe every day. Maintaining an adequate blood supply, though, is no easy task, particularly in low- and middle-income countries (LMIC). The demand for O–negative blood — the universal donor type — often exceeds supply and donations have a limited shelf life.

I always wanted to understand life. What moves us? What allows us to heal and thrive? And what goes wrong when we get sick or when we eventually stop breathing and die? My search for answers to these stupendously ambitious questions led me, it now seems inexorably, to mitochondria. In biology classes from high school through university, I learned that mitochondria are little objects that reside within each cell and serve as “powerhouses,” combining oxygen and food to yield energy for the body.

TL;DR A new study found no genetic changes in human cells exposed to 5G radiation, even at high intensities. Researchers ruled out heating effects, confirming previous claims of harm were likely due to temperature, not EMF. 5G waves can’t penetrate deep into the skin, and aren’t scrambling your DNA. The 5G conspiracy crowd has been banging their drum for years, but scientists have now directly tested their central claims. In a useful but unsurprising result, a new 5G study found that blasting

At the time, the treatment was experimental, but it worked: The cells targeted the cancer and eradicated it. Thirteen years later, Whitehead is still cancer-free.

Two signal trains circulate a loop and are duplicated at a T-junction onto an open-ended section of wire. The first (7-0) causes the sheathed end of the wire to become exposed. The second (6-0) re-sheathes the exposed end, leaving the wire one cell longer than before. Codd's cellular automaton is

If you took high school biology, you probably learned about cell division: a crucial process in all life forms officially called mitosis. For over one hundred years, students have learned that during mitosis, a parent cell becomes spherical before dividing into two daughter cells of the same size and shape. A new study, however, might rewrite many, many biology textbooks. Researchers revealed that mitosis doesn’t always feature cell rounding (when a parent cell becomes spherical), meaning that

When alerted to the presence of such invaders, mast cells can create mucus, trigger swelling and itching, and make muscles contract in our airways, stomach, and intestines. While these symptoms allow the body to destroy or expel invaders, oversensitive mast cells cause allergic reactions, including life-threatening and hard-to-treat conditions. As

In colloids as in biofilms, these interactions are governed by two opposing forces. One is repulsive: Two particles or two cells can’t physically occupy the same space at the same time. The other force is attractive. Cells are covered with sticky proteins that can fasten two cells together, much like the medium binding a colloid. If the repulsive force is stronger, cells don’t aggregate. But if the attractive force is stronger, it can spark the initial formation of a biofilm. What differentiate
