Insight into brain’s waste clearing system may shed light on brain diseases

Posted by in categories: biotech/medical, engineering, neuroscience

Like the lymphatic system in the body, the glymphatic system in the brain clears metabolic waste and distributes nutrients and other important compounds. Impairments in this system may contribute to brain diseases, such as neurodegenerative diseases and stroke.

A team of researchers in the McKelvey School of Engineering at Washington University in St. Louis has found a non-invasive and non-pharmaceutical method to influence glymphatic transport using , opening the opportunity to use the method to further study diseases and . Results of the work are published in the Proceedings of the National Academy of Sciences on May 15.

Hong Chen, associate professor of biomedical engineering in McKelvey Engineering and of in the School of Medicine, and her team, including Dezhuang (Summer) Ye, a postdoctoral research associate, and Si (Stacie) Chen, a former postdoctoral research associate, found the first direct evidence that focused , combined with circulating microbubbles—a technique they call FUSMB—could mechanically enhance glymphatic transport in the mouse brain.

Russia’s war on Ukraine has caused lasting damage to international spaceflight cooperation

Posted by in categories: Elon Musk, internet, satellites

This article gives a clear and chilling assessment of the impact of the Ukraine conflict on the future of collaborative space exploration; in doing so it highlights how humankind’s habitual tendency towards wars severally slow, if not completely halt, our urgent reach for the stars. As that old warrior Churchill once said„ ‘Jaw, jaw is always better than War, war!’


Russia’s invasion of Ukraine in February 2022 has resulted in hundreds of thousands of deaths, millions homeless and displaced and billions of dollars of damage in infrastructure. The conflict has also had less immediate but significant impacts on other areas, including on the space industries of Ukraine and Russia, but also globally in terms of the launch market, spaceflight activity and international cooperation.

In the wake of the start of the conflict on Feb. 24, 2022, and resulting international backlash against Russia, the then-head of the Russian space agency Dmitry Rogozin threatened to end its cooperation with the West on the International Space Station (ISS) program over sanctions imposed on Russia. He also issued a threat to SpaceX founder and CEO Elon Musk for the company’s role in providing connectivity through its Starlink satellites.

Waterloo engineers task AI robot to help people with dementia

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

Harnessing the power of Artificial Intelligence to help patients keep track of their medicines, glasses, and even their keys.

It is estimated that the number of people with dementia will significantly increase in the coming years, with some estimates projecting numbers to double in the United States by 2050.

One of the ramifications of dementia, amongst many, is the loss of memories, especially episodic memories. These are of a long-term nature and allow us to recall instances ranging from “How was my first day at school” to sensory information such as “What did I see” and “How did it smell.”

Human DNA is surprisingly easy to find in the environment

Posted by in category: biotech/medical

Human DNA is easy to find in the environment, with samples of such good quality it can identify individual people. That’s both a boon and a burden for researchers.

A new study out of the University of Florida has found that human DNA samples, some of extremely high quality, are easily found in the environment wherever researchers looked, offering both a bounty for scientific research but also an ethical dillema not easily solved.
