Life Expectancy Falling for Adults Without a Bachelor’s Degree

Posted by in categories: biotech/medical, education

Summary: Since 2010, there has been an absolute rise in mortality for adults without a college degree. For those with higher education experience, mortality rates have decreased during the same time period.

Life expectancy in the United States dropped in 2020 due to COVID-19, but, for American adults without a college degree, the increase in mortality in adulthood occurred even earlier, according to a new study authored by Anne Case and Sir Angus Deaton of Princeton University.

Should We Genetically Engineer Carbon-Hungry Trees?

Posted by in categories: genetics, innovation

“If you don’t do both, you’re not going to get very far,” he says. He wants to bring “carbon drawdown” technologies into the conversation with genetically modified trees.

Last year, DeLisi organized a workshop with a team of heavy hitters — Sir Richard Roberts (biochemist, Nobel laureate, and staunch advocate for GMOs), Val Giddings (a geneticist at the Information Technology and Innovation Foundation), and researchers from Oak Ridge National Laboratory — to create solutions, like genetically modifying carbon-hungry trees.

And they are close.

This L.A. start-up is building tiny injectable robots to attack tumors

Posted by in categories: biotech/medical, chemistry, robotics/AI

Doctors take a microscopic craft loaded with cancer-killing chemicals, inject it into the human body, and drive it to a malignant tumor to deliver its payload before making a quick exit. The plan is to move to clinical trials by 2023.


Chemotherapy and radiation can cause too much collateral damage to treat some brain tumors. Crumb-sized robots could be the solution.

Bacteria Could Be The First Organisms Found to Use Quantum Effects to Survive

Posted by in categories: biological, chemistry, quantum physics

Bacteria have been found exploiting quantum physics to survive.


Oxygen is life to animals like us. But for many species of microbe, the smallest whiff of the highly reactive element puts their delicate chemical machinery at risk of rusting up.

The photosynthesizing bacterium Chlorobium tepidum has evolved a clever way to shield its light-harvesting processes from oxygen’s poisonous effects, using a quantum effect to shift its energy production line into low gear.

Where Electric Car Batteries Go When They Die

Posted by in categories: energy, sustainability, transportation

Global battery recycling industries are a new beginning for old energy storage.


When your kid looks at you with those big, innocent eyeballs and asks, “Where do lithium ion electric car batteries go when they die?” Without hesitation—because kids that age still believe you know everything—you read them this article:

Scientists are weaponizing viruses to solve a huge problem

Posted by in categories: bioengineering, biotech/medical

Now scientists are hoping to use the knowledge about CRISPR systems to engineering phages to destroy dangerous bacteria.


As the world fights the SARS-CoV-2 virus causing the COVID-19 pandemic, another group of dangerous pathogens looms in the background.

Oops! The “World’s Oldest Meteorite Impact Crater” Isn’t an Impact Crater After All

Posted by in category: futurism

Several years after scientists discovered what was considered the oldest crater a meteorite made on the planet, another team found it’s actually the result of normal geological processes.

During fieldwork at the Archean Maniitsoq structure in Greenland, an international team of scientists led by the University of Waterloo ’s Chris Yakymchuk found the features of this region are inconsistent with an impact crater. In 2012, a different team identified it as the remnant of a three-billion-year-old meteorite crater.

“Zircon crystals in the rock are like little time capsules,” said Yakymchuk, a professor in Waterloo’s Department of Earth and Environmental Sciences. “They preserve ancient damage caused by shockwaves you get from a meteorite impact. We found no such damage in them.”

The Disturbing Link Between Psychiatric Illness and Accelerated Aging

Posted by in category: life extension

The results of this study demonstrate a clear relationship between psychopathology and rate of aging. Remarkably, this relationship was obvious by the age of 45. By that time, those with the upper 10% of psychopathology factor (p-factor) scores had aged approximately 5.3 more years than those with the lowest 10% of p-factor scores.


Is a history of psychiatric illness associated with more rapid aging?

Study finds cancer cells may evade chemotherapy

Posted by in categories: biotech/medical, health

In the study, the researchers found that when AML cells were exposed to chemotherapy, a subset of the cells went into a state of hibernation, or senescence, while at the same time assuming a condition that looked very much like inflammation. They looked similar to cells that have undergone an injury and need to promote wound healing—shutting down the majority of their functions while recruiting immune cells to nurse them back to health.


Cancer cells can dodge chemotherapy by entering a state that bears similarity to certain kinds of senescence, a type of “active hibernation” that enables them to weather the stress induced by aggressive treatments aimed at destroying them, according to a new study by scientists at Weill Cornell Medicine. These findings have implications for developing new drug combinations that could block senescence and make chemotherapy more effective.

In a study published Jan. 26 in Cancer Discovery, a journal of the American Association for Cancer Research, the investigators reported that this biologic process could help explain why cancers so often recur after treatment. The research was done in both organoids and mouse models made from patients’ samples of acute myeloid leukemia (AML) tumors. The findings were also verified by looking at samples from AML patients that were collected throughout the course of treatment and relapse.
