Cambridge researchers have developed ‘mini brains’ that allow them to study a fatal and untreatable neurological disorder causing paralysis and dementia – and for the first time have been able to grow these for almost a year.
A common form of motor neuron disease, amyotrophic lateral sclerosis, often overlaps with frontotemporal dementia (ALS/FTD) and can affect younger peo… See More.
A team of researchers publishing in Aging have shown that resveratrol reduces inflammation and partially restores function in a rat model of spinal injury.
In line with previous research
This is far from the first study that aimed to use approaches associated with aging research in order to spur regeneration. For example, we have previously reported that removing senescent cells aids in spinal cord regeneration in a rodent model, at least partially because of the associated reduction in inflammation.
The COVID-19 crisis led to fundamental changes in how we conduct business. The big question today is whether these innovations will be sustained and built upon after the crisis.
Circa 2020 o.o Basically a molecular printer could make your own vaccine for any disease.
Tesla Inc is building mobile molecule printers to help make the potential COVID-19 vaccine being developed by CureVac in Germany, the electric-car maker’s Chief Executive Officer, Elon Musk, tweeted on Wednesday.
Dr. Ann Marie Kimball (https://epi.washington.edu/faculty/kimball-ann-marie/) is a physician, epidemiologist and currently holds the roles of Associate Fellow at the international affairs think tank Chatham House, and Vice Chair, COVID 19 task force, at The Rotary Foundation / Rotary International.
Previously, Dr. Kimball served as a strategic advisor to the Rockefeller Foundation, supporting the strengthening and development of strategies for Ebola, post-Ebola, and health crisis response, including planning and guiding the formation of a regional disease surveillance network in collaboration with Connecting Organizations for Regional Disease Surveillance (CORDS).
Before joining the Rockefeller Foundation, Dr. Kimball served as technical and strategic lead for the Bill and Melinda Gates Foundation surveillance strategy formation.
Prior to Gates, Dr. Kimball served as Professor of Epidemiology for the University of Washington (UW), School of Public Health, with adjunct appointments in Medicine (Bioinformatics and Infectious Diseases) and the Jackson School of Foreign Affairs. During her tenure at UW, Dr. Kimball founded and directed the APEC Emerging Infections Network, and led research and training programs in Surveillance and Informatics in Peru and Thailand.
Dr. Kimball’s research focus on global trade and emerging infections earned her a Fulbright New Century Scholars award and a Guggenheim Scholars award.
Dr. Kimball is also the author of Risky Trade: Infectious Diseases in an Era of Global Trade, which was highly reviewed by NEJM, Emerging Infections and Lancet. She has authored numerous scientific publications, and served on numerous Institute of Medicine panels. She is also a fellow in the American College of Preventive Medicine and member of the National Biosurveillance Advisory group (NBAS) from the Centers for Disease Control.
Recent advancements in biotechnology have immense potential to help address many global problems; climate change, an aging society, food security, energy security, and infectious diseases.
Biotechnology is not to be confused with the closely related field of biosciences. While biosciences refer to all the sciences that study and understand life, biology, and biological organisms, biotechnology refers to the application of the knowledge of biosciences and other technologies to develop tech and commercial products. Biotechnology is the application of innovation to biosciences in a bid to solve real-world medical problems.
Throw Artificial Intelligence into the mix and we suddenly have a really interesting pot of broth. Several AI trends have already proven beneficial to the development of biotechnology. Dr. Nathan S. Bryan, an inventor, biochemist and professor, who made a name for himself as an innovator and pioneer in nitric oxide drug discovery, commercialization, and molecular medicine, offers his insights on these contributions.
This type of cell could lead to an unlimited cell division in human cells aka a forever lifespan 😃 #immortality
“The sequencing and posting of the HeLa genome brought into sharp relief important ethical and policy issues,” said Dr. Collins. “To understand the family’s perspectives, we met with them face to face three times over four months, and listened carefully to their concerns. Ultimately, we arrived at a path forward that respects their wishes and allows science to progress. We are indebted to the Lacks family for their generosity and thoughtfulness.”
The HeLa Genome Data Use Agreement
The new controlled access policy for full genome sequence data from HeLa cells will give the Lacks family the ability to have a role in work being done with the HeLa genome sequences and track any resulting discoveries. Under the policy, biomedical researchers who agree to abide by terms set forth in the HeLa Genome Data Use Agreement will be able to apply to NIH for access to the full genome sequence data from HeLa cells. Along with representatives from the medical, scientific, and bioethics communities, two representatives of the Lacks family will serve on NIH’s newly formed, six-member working group that will review proposals for access to the HeLa full genome sequence data. In addition, NIH-funded researchers who generate full genome sequence data from HeLa cells will be expected to deposit their data into a single database for future sharing through this process. The database study page will be accessible after the embargo lifts at this url: http://www.ncbi.nlm.nih.gov/projects/gap/cgi-bin/study.cgi?s…0640.v1.p1. Other investigators will be encouraged to respect the wishes of the family and do the same. Importantly, all researchers who use or generate full genomic data from HeLa cells will now be asked to include in their publications an acknowledgement and expression of gratitude to the Lacks family for their contributions.
Circa 2018
The secrets to immortality may lie in an unexpected place — fruit fly stem cells. Researchers led by Howard Hughes Medical Institute (HHMI) Investigator Yukiko Yamashita have found that some stem cells have a genetic trick to remain young forever across generations. While some areas of the fruit fly genome get shorter as they age, some reproductive cells are able to fix that shortening. Once observed only in yeast, this work, reported in eLife, has revealed more about aging, and how some cells can avoid it.
This work focused on critical genes in ribosomal DNA, rDNA. Ribosomes are cellular organelles that act as protein factories. That rDNA is repeated in several areas of the genome because many ribosomes are needed to make all of the proteins the body needs. Five chromosomes each have spots with hundreds of copies of rDNA. However, that type of redundant sequence can be difficult for cells to replicate accurately every time cell division happens.
