Glioblastoma is one of the most aggressive types of brain cancer known to man. For many, the chance of survival is often low. However, a new type of brain tumor therapy could help change things for the better. The therapy, which relies on destroying the “power source” of the cancer, has shown considerable success in mice. The scientists are hopeful it will work the same in humans.

The new therapy hopes to destroy the “power source” of glioblastoma tumors. A new study led by Israeli scientists shows that glioblastoma relies on specific brain cells to fuel the growth of its tumors. As a result, scientists began to look at ways to treat cancer by removing those cells instead. The new brain tumor therapy could completely starve out the cancer cells, allowing patients to enter remission.

Normally doctors would use chemotherapy to target the tumors directly. However, by removing brain cells called Astrocytes, scientists found they could starve out glioblastoma tumors in mice. Further, the tumors remained gone for as long as the astrocytes were repressed. And, even when they stopped suppressing, Dr. Lior Mayo, lead author on the study, says that 85 percent of mice stayed in remission.

According to the researcher, the same technology could be applied to beetles and cicadas as well.

It’s a fun and futuristic vision: an army of remotely controlled cyborg insects that can infiltrate hard to reach locations or monitor crops.

But scientists will have to advance the tech carefully — nobody wants to risk a cyborg cockroach uprising.

Many insects are powerful, agile flyers. One reason is that most have four wings, which gives them fine control over their direction of flight and their orientation through pitch, roll, and yaw adjustment.

In recent years, aerodynamicists, engineers, and roboticists have attempted to copy insect-like flight by building tiny flying robots. The main thing they’ve discovered is just how difficult this is.

At its height, the Roman Empire was home to about 30% of the world’s population, and in many ways the pinnacle of human advancement. Rome became the first city in history to reach one million inhabitants and was a center of technological, legal, and economic progress. An empire impossible to topple, stable and rich and powerful.
Until it wasn’t anymore. First slowly then suddenly, the most powerful civilization on earth collapsed. If this is how it has been over the ages, what about us today? Will we lose our industrial technology, and with that our greatest achievements, from one dollar pizza to smartphones or laser eye surgery? Will all this go away too?

Did they unlock one of the vital keys to stop aging?


According to a recent National Eye Institute (NEI) study in mice, loss of the protein pigment epithelium-derived factor (PEDF), which protects retinal support cells, may promote age-related changes in the retina.

Age-related retinal diseases, such as age-related macular degeneration (AMD), can cause blindness since the retina is the light-sensitive tissue at the back of the eye. The new information could help develop medicines to stop AMD and other aging conditions of the retina. The research was published in the International Journal of Molecular Sciences. NEI is part of the National Institutes of Health.

“People have called PEDF the ‘youth’ protein because it is abundant in young retinas, but it declines during aging,” said Patricia Becerra, Ph.D., chief of NEI’s Section of Protein Structure and Function and senior author of the study. “This study showed for the first time that just removing PEDF leads to a host of gene changes that mimic aging in the retina.”
