A new framework bridges a gap in understanding RNA therapeutics by linking the structure of lipid nanoparticles to immune response. It can help scientists and engineers expand the use of RNA medicines beyond vaccines to other therapeutic applications.

Chuck Brooks serves as President and Consultant of Brooks Consulting International. Chuck also serves as an Adjunct Professor at Georgetown University in the Cyber Risk Management Program, where he teaches graduate courses on risk management, homeland security, and cybersecurity.

Chuck has received numerous global accolades for his work and promotion of cybersecurity. Recently, he was named the top cybersecurity expert to follow on social media, and also as one top cybersecurity leaders for 2024. He has also been named “Cybersecurity Person of the Year” by Cyber Express, Cybersecurity Marketer of the Year, and a “Top 5 Tech Person to Follow” by LinkedIn” where he has 120,000 followers on his profile.

As a thought leader, blogger, and event speaker, he has briefed the G20 on energy cybersecurity, The US Embassy to the Holy See, and the Vatican on global cybersecurity cooperation. He has served on two National Academy of Science Advisory groups, including one on digitalizing the USAF, and another on securing BioTech. He has also addressed USTRANSCOM on cybersecurity and serves on an industry/government Working group for DHS CISA focused on security space systems.

In the movie “Jurassic Park,” scientists extracted DNA that had been preserved in amber for millions of years, and used it to create a population of long-extinct dinosaurs.

Researchers at The Jackson Laboratory (JAX), the Broad Institute of MIT and Harvard, and Yale University, have used artificial intelligence to design thousands of new DNA switches that can precisely control the expression of a gene in different cell types. Their new approach opens the possibility of controlling when and where genes are expressed in the body, for the benefit of human health and medical research, in ways never before possible.

“What is special about these synthetically designed elements is that they show remarkable specificity to the target cell type they were designed for,” said Ryan Tewhey, PhD, an associate professor at The Jackson Laboratory and co-senior author of the work. “This creates the opportunity for us to turn the expression of a gene up or down in just one tissue without affecting the rest of the body.”

In recent years, genetic editing technologies and other gene therapy approaches have given scientists the ability to alter the genes inside living cells. However, affecting genes only in selected cell types or tissues, rather than across an entire organism, has been difficult. That is in part because of the ongoing challenge of understanding the DNA switches, called cis-regulatory elements (CREs), that control the expression and repression of genes.

Scientists have identified a natural compound that halts the process involved in the progression of certain forms of cancer and demyelinating conditions—those that damage the sheath, known as myelin, that surrounds neurons—such as multiple sclerosis.

The microbiome has a profound impact on host health that extends to the host’s young ones. Studies in mice have shown that maternal gut bacteria play a role in offspring behavior and placental growth during pregnancy.^1,2 Yet, the effects of the paternal microbiome on the health of their progeny remained relatively unexplored.

In a new study, scientists found that altering the gut microbiome of male mice negatively affected the health and lifespan of their offspring through epigenetic changes in the sperm.³ The results, published in Nature, offer insights into a gut-germline axis that mediates the effects of the microbiome on health and disease across generations.

If you’re ever faced with trying to pick up a grain of rice with a pair of chopsticks, spare a thought for the scientists behind this latest innovation, which has been called “a medical breakthrough on the verge of happening.” They’ve painstakingly built a soft robot with the capacity to carry different types of drugs through the body. It’s the size of a grain of rice, and can be driven to various internal targets via magnetic fields.

Researchers in the School of Mechanical and Aerospace Engineering (MAE) at Nanyang Technological University, Singapore (NTU Singapore), have built on earlier work to create a grain-sized soft robot that can enter the body and be controlled by magnetic fields to travel to a specific target. Once there, it can quickly or slowly release the medication it has stored in its tiny frame.

In the consequent tweets, the biohacker attributed his successful hair regeneration to a multi-faceted approach. The key to his transformation has been the strategic use of vitamins and nutrients, particularly protein and Omega-3 fatty acids, which have played a crucial role in restoring his hair.

In addition to nutrition, he has developed a personalised topical formula tailored to his genetics, that includes melatonin, caffeine, and Vitamin D3. He has also incorporated red light therapy into his daily routine, even wearing a specialised hat to administer this treatment throughout the day.

Another critical component of Johnson’s regimen is oral minoxidil, a topical hair-loss drug. However, he stressed that it is only considered safe at low doses as it can lead to unpleasant side effects, including excessive hair growth and headaches.
