Cancer and other diseases have another means of travel.
The continuous network of fluid-filled compartments crosses organ barriers and might serve as a conduit for tumor cells to spread.

The short and long view of how AI is changing health
As the electronic health record grows in detail, the possibilities for customized care are becoming a reality. This article features some useful links to things in the making.
While AI is driving value in all aspects of our lives, there are times where it’s hard to separate the aspirations of those who want to use it to do good from those leverag ing AI today to positively impact real change in health and medici ne.
While AI is driving value in all aspects of our lives, there are times where it’s hard to separate the aspirations of those who want to use it to do good from those leverag ing AI today to positively impact real change in health and medici ne.I have the privilege of working with many talented leaders and organizations that are truly making health and medical services better by harnessing the power of healthcare’s data tsunami using AI and other analytical solutions.
COVID-19, p art t wo
There is growing optimism in how we manage COVID-19 going forward to restore many of the daily living activities we miss and treasure. One of the good things we learned from COVID-19 is that, when faced with a challenge, health systems are capable of agile transformation. As part of this, we also demonstrated that AI could drive a “short time to value.”
Gene That Could Help Prevent or Delay Onset of Alzheimer’s Disease Identified
Summary: Boosting the expression of the ABCC1 gene may not only reduce amyloid plaques in the brain, it might also delay the onset of Alzheimer’s disease.
Source: TGen.
Findings of a study by the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggest that increasing expression of a gene known as ABCC1 could not only reduce the deposition of a hard plaque in the brain that leads to Alzheimer’s disease, but might also prevent or delay this memory-robbing disease from developing.
DNA robots designed in minutes instead of days
Someday, scientists believe, tiny DNA-based robots and other nanodevices will deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics.
Researchers took a big step toward that future by developing a new tool that can design much more complex DNA robots and nanodevices than were ever possible before in a fraction of the time.
In a paper published today in the journal Nature Materials, researchers from The Ohio State University—led by former engineering doctoral student Chao-Min Huang—unveiled new software they call MagicDNA.
Age-related diseases can be linked by genetics
In a research paper published in Nature Aging, the team reports using a novel approach to provide the first data-driven classification of multiple diseases obtained using human genetic and medical data freely available from the UK Biobank.
Co-author Professor Linda Partridge (UCL Institute of Health Aging and Max Planck Institute for Biology of Aging) said: Advancing age is the main risk for major diseases, including cancer, dementia, and cardiovascular disease. Understanding the molecular links between the aging process and age-related diseases could allow them to be targeted with drugs to improve late-life health.
The striking finding from the study was that diseases with a similar age of onset were genetically more similar to each other than they were to diseases in the other three clusters.

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a revolutionary technology that gives scientists the ability to alter DNA. On the one hand, this tool could mean the elimination of certain diseases. On the other, there are concerns (both ethical and practical) about its misuse and the yet-unknown consequences of such experimentation.
“The technique could be misused in horrible ways,” says counter-terrorism expert Richard A. Clarke lists biological weapons as one of the potential threats, “Threats for which we don’t have any known antidote.” CRISPR co-inventor, biochemist Jennifer Doudna, echos the concern, recounting a nightmare involving the technology, eugenics, and a meeting with Adolf Hitler.
Should humanity even have access to this type of tool? Do the positives outweigh the potential dangers? How could something like this ever be regulated, and should it be? These questions and more are considered by Doudna, Clarke, evolutionary biologist Richard Dawkins, psychologist Steven Pinker, and physician Siddhartha Mukherjee.

Virtual Humans Are Equal to Real Ones in Helping People Practice New Leadership Skills
Summary: Computer-generated, or virtual humans, prove to be just as good as humans in helping people practice leadership skills.
Source: Frontiers.
A virtual human can be as good as a flesh-and-blood one when it comes to helping people practice new leadership skills. That’s the conclusion from new research published in the journal Frontiers in Virtual Reality that evaluated the effectiveness of computer-generated characters in a training scenario compared to real human role-players in a conventional setting.
The semiconductor shortage is here to stay, but it will affect chip companies differently
This article is part of a series tracking the effects of the COVID-19 pandemic on major businesses and sectors. For other articles and earlier versions, go here.
A global shortage of semiconductors — chips that power massive data-centers, modern autos and countless digital devices — has roiled global manufacturing and is not expected to end soon. It isn’t a blanket problem, however, as different sectors within the chip industry will continue to be affected by the shortage in different ways.
As the industry entered 2020, high demand was expected in the mobile chip area because of the rollout of 5G devices. That path was turned on its head when COVID-19 became a global pandemic, driving millions, if not billions, of people into the safety of their homes to work, go to school, be entertained and to socialize.
