By taking their microscopes to the skeletal structures of the human body, scientists in Australia have unearthed an entirely new type of bone cell, one they believe may play an important role in the development of various bone diseases. The new cell switches on a number of unique genes, shedding new light on the way bones degenerate and reform and opening up new possibilities for the treatment of conditions like osteoporosis.

Among the many moving parts that scientists suspect may play a role in Alzheimer’s disease is one known as the glymphatic system, which is thought to flush waste chemicals from the brain. A new study has demonstrated how this recently discovered system might be kicked into gear via ultrasound, with the technique proving effective in stimulating its activity in patients as part of early human trials. read more

Artificial intelligence is starting to combine with smartphone technology in ways that could have profound impacts on the way we monitor health, from tracking blood volume changes in diabetics to detecting concussions by filming the eyes. Using the technology to spot melanoma in its early stages is another exciting possibility, and a new deep-learning system developed by Harvard and MIT scientists promises a new level of sophistication, by using a method commonly used by dermatologists known as the “ugly duckling” criteria.

How many Form of Ice?

Researchers have confirmed the crystal structure of a new form of ice, adding to a growing list of known ice types

Owing to the many different ways atoms can be arranged within the material, ice can exist in many more forms than what’s known as ice I, the type we’re all familiar with. Scientists have actually categorized 18 different types of the material, each with its own unique crystalline structure, and now have added another, called ice XIX, to the list.

Regrow Your Muscles?

Researchers have discovered an enzyme that could aid in the repair of muscles

Although muscle stem cells are able to grow and repair torn muscle tissue after we sustain an injury, they become less effective as we age. Now researchers at the Australian Regenerative Medicine Institute at Monash University have discovered a novel protein that can trigger the proliferation of these stem cells and promote healing, offering hope not only to those who have torn a muscle, but also the elderly and those suffering severe muscle wasting diseases.

While studying the cells that migrated to the site of a muscle injury in zebrafish, the researchers noticed macrophages appeared to play a role in triggering the regeneration of muscle stem cells. Macrophages are a type of white blood cell that converge on the site of any injury or infection in the body to clear away debris and promote healing. Professor Currie calls them “the clean-up crew of the immune system.”

To study the regeneration of skeletal muscle, the research team, led by Professor Peter Currie, turned to zebrafish. The zebrafish is a popular animal model for studying cell regeneration due to their quick reproduction rate, the fact that they share at least 70 percent of their genes with humans, and the ease with which they can be manipulated experimentally. They are also transparent, providing a convenient window for the viewing of actual regeneration in living muscle.

When the heart is injured it can’t repair itself, meaning that heart failure often requires a transplant of the whole organ. But now, scientists at EPFL have developed an artificial aorta that can help pump blood, taking some of the pressure off the heart and reducing or even eliminating the need for a transplant.

WND Exclusive – WHO changed virus test parameter the day Biden took office

from Brent Smith at World Net Daily:

On Jan. 20, 2021, the WHO (World Health Organization) posted an important bulletin regarding polymerase chain reaction (PCR) testing for COVID-19. What else happened on 20 January that was important? That’s right. It was the very same day Joe Biden was sworn in as the 46th president of the United States. But I’m sure the WHO release was purely coincidental.

LifeSite News claims that the notice was released one hour after Biden took office. Although I can’t confirm that exact time, the WHO guidance bulletin is dated Jan. 20, 2021. read more
