I believe nanomachines or new advanced rna antivirals that can target one’s own variants of viruses will be game changers to prevent future global pandemics. Also eventually new genetic engineering could allow for the end to all viruses with some sorta Omni vaccine.

Measurement(s) Pandemic-and epidemic-prone disease outbreaks Technology Type(s) Text mining using R Sample Characteristic — Organism Disease outbreaks Sample Characteristic — Environment spatiotemporal region Sample Characteristic — Location Global.

An interview with J. Storrs Hall, author of the epic book “Where is My Flying Car — A Memoir of Future Past”: “The book starts as an examination of the technical limitations of building flying cars and evolves into an investigation of the scientific, technological, and social roots of the economic…

J. Storrs Hall or Josh is an independent researcher and author.

He was the founding Chief Scientist of Nanorex, which is developing a CAD system for nanomechanical engineering.

Resurrection biology — attempting to bring strings of molecules and more complex organisms back to life — is gaining traction in labs around the world.

The work is a far cry from the genetically engineered dinosaurs that escape in the blockbuster movie “Jurassic Park,” although for some scientists the ultimate goal is de-extinction and resurrecting animals and plants that have been lost.

Other researchers are looking to the past for new sources of drugs or to sound an alarm about the possibility of long-dormant pathogens. The field of study is also about recreating elements of human history in an attempt to better understand how our ancestors might have lived and died.

The CHOOSE system, an innovative approach combining brain organoids and genetics, transforms autism research by allowing detailed analysis of mutations and their effects on brain development.

Does the human brain have an Achilles heel that ultimately leads to Autism? With a revolutionizing novel system that combines brain organoid technology and intricate genetics, researchers can now comprehensively test the effect of multiple mutations in parallel and at a single-cell level within human brain organoids.

This technology, developed by researchers from the Knoblich group at the Institute of Molecular Biotechnology (IMBA) of the Austrian Academy of Sciences and the Treutlein group at ETH Zurich, permits the identification of vulnerable cell types and gene regulatory networks that underlie autism spectrum disorders. This innovative method offers unparalleled insight into one of the most complex disorders that challenge the human brain with implications that bring autism clinical research much-needed hope.

A new paper in the journal Genome Biology and Evolution, published by Oxford University Press, finds that genetic material from Neanderthal ancestors may have contributed to the propensity of some people today to be “early risers,” the sort of people who are more comfortable getting up and going to bed earlier.

Human Evolution and Genetic Adaptation

All anatomically modern humans trace their origin to Africa around 300 thousand years ago, where environmental factors shaped many of their biological features. Approximately seventy thousand years ago, the ancestors of modern Eurasian humans began to migrate out to Eurasia, where they encountered diverse new environments, including higher latitudes with greater seasonal variation in daylight and temperature.

The holiday season means presents galore — but in the case of at-home DNA tests, some gifts may be better left unopened.

As experts told USA Today, the prevalence of self-serve DNA testing has made it much more likely that people discover painful family secrets — for instance, that one or both of your parents are not your genetic relatives — upon getting their results.

For years now, we’ve come across reports about people learning of their parents’ affairs via DNA testing kits from companies like Ancestry or 23andme.
