Hemophilia ‘cures’ are proving gene therapy really is all it’s cracked up to be

The latest example is hemophilia, and the incredible recent progress toward a cure (or cures) show just how much potential the field really has.About 1 in 5,000 males is born with Hemophilia A, which has to do with the function of the protein factor VIII, and 1 in 30,000 is born with hemophilia B, due to defective versions of factor IX.

How MIT’s new biological ‘computer’ works, and what it could do in the future

How MIT’s new biological ‘computer’ works, and what it could do in the future With a fully realized ability to program cell behavior as reliably as we do computer behavior, there’s no telling what biological computing could accomplish.In 2013, this same team designed the computing strain that preceded this one: a biological “state machine.

In mice, a possible means to counteract multiple sclerosis

In mice, a possible means to counteract multiple sclerosis In either case, the length of the cell, the connection between the in-point and the out-point, is called the axon.It is responsible for carrying signals over whatever distance the signal must travel to get to the next neuron, or its ultimate destination.

Scientists invent a new kind of nanoscale imaging for living cells

Scientists invent a new kind of nanoscale imaging for living cells They also move, and all that motion makes it practically impossible to get good high-resolution images of cells and what’s inside them.To get around this, a team of scientists from the University of Texas at Austin have put their heads together and demonstrated a whole different way of imaging cells, called “thermal noise imaging.

Drug-resistant bacteria tricked into dropping their shields become vulnerable once again

Drug-resistant bacteria tricked into dropping their shields become vulnerable once again In search of another way to manage the endless slog against antibiotic-resistant bacteria, scientists just figured out how to bait bacteria into developing an Achilles’ heel.Not all drug resistance works the same: It depends on the type of antibiotic the bacteria have evolved to resist.

Scientists create new fluorescent protein to monitor the cell cycle

Scientists create new fluorescent protein to monitor the cell cycle When you need new cells, they can be created through a process called mitosis, whereby a cell makes a copy of itself.A new technique from Stanford (PDF) allows the cell cycle to be observed with more precision than ever before.

Researchers create a tiny tractor beam that totes bacteria around

Researchers create a tiny tractor beam that totes bacteria around “The principle underlying this laser beam is similar to the concept to be found in the television series Star Trek,” says Dr.In their new method, the Bielefeld researchers use a second laser beam as a single-cell optical trap — in other words, a tiny tractor beam — so that the cells float under the microscope and can be moved at will.

Scientists discover way to eliminate chemotherapy side effects in mice

Scientists discover way to eliminate chemotherapy side effects in mice Which is why it’s exciting to hear that scientists have published a paper describing how these side effect might be nullified.“Chemotherapeutic drugs are an effective anti-cancer strategy but come with a number of side effects due to the lack of specificity against cancer cells,” Dr.

Brain cells, beware: Researchers have created the world smallest hammer

Brain cells, beware: Researchers have created the world smallest hammer The world’s smallest hammer has been created to study what happens to brain cells when we hit our head.” Along with Megan Valentine, Adele Doyle, and research student Luke Patterson, Foster will study how impact affects neural stem cells.

Scientists use stem cells to grow animal-free pork in a lab

Scientists use stem cells to grow animal-free pork in a lab ) “What the paper describes is research designed to generate muscle from a newly established pig stem-cell line, rather that from primary cells taken directly from a pig,” co-author Dr.These are all questions I had to figure out in the lab before the cells could be turned into muscle.

Stanford scientists ‘program’ mice to glow like fireflies

Stanford scientists ‘program’ mice to glow like fireflies Moreau; scientists at Stanford University really have come up with a way to make mice glow in the dark by producing firefly proteins.And it could just turn out to be a major advance in the development of future designer vaccines or even cancer therapies.

Scientists find another reason to cut your sugar intake: Alzheimer's disease

Scientists find another reason to cut your sugar intake: Alzheimer's disease researchers say they've spotted the molecular "tipping point" that could explain sugar's ties to Alzheimer's disease.Their findings provide further evidence that there might be a link between high blood sugar levels and the memory-robbing disease, though they don't prove that sugar causes Alzheimer's outright.

Can you hear me now? Researchers one step closer to reversing hearing loss

Can you hear me now? Researchers one step closer to reversing hearing loss Humans are born with 30,000 sound-sensing hair cells, which die off over time due to loud noises, medications, and natural aging.But a few years ago researchers from Massachusetts Eye and Ear managed to restore partial hearing in mice by converting a small number of inner ear cells into hair cells.

Scientists may have found a way to make old blood stem cells act young again

Scientists may have found a way to make old blood stem cells act young again To achieve this, they’ve discovered a protein capable of boosting blood stem cells, which prompt them to act like the stem cells of younger people.More: Scientists may have discovered how to reverse the natural aging process “Older stem cells have several disadvantages,” Dr.
