Using cannabis may cause changes in the human body’s epigenome, a study of over 1,000 adults suggests. The epigenome functions like a set of switches, activating or deactivating genes to change how our bodies function.

“We observed associations between cumulative marijuana use and multiple epigenetic markers across time,” says Lifang Hou, a preventative medical doctor and epidemiologist from Northwestern University Feinberg School of Medicine.

Cannabis is a commonly used substance in the United States, with 49 percent of people trying it at least once, Hou and a team of US researchers report in their published paper. Some US states and other countries have made it legal, but we still don’t fully understand its effects on our health.

In March 2020, an experiment in science philanthropy was hatched in the span of a five-minute call.

Patrick Collison, the now 34-year-old billionaire CEO of the online payments company Stripe, and economist Tyler Cowen were chewing over a shared concern: Scientific progress seemed to be slowing down. As the first pandemic lockdowns went into effect, researchers were in a holding pattern, waiting to hear if they could redirect their federal grants to COVID-related work. Collison and Cowen worried that the National Institutes of Health wasn’t moving quickly enough, so they launched Fast Grants to get emergency research dollars to virologists, coronavirus experts, and other scientists rapidly.

“We thought: Let’s just do this,” Cowen recalls. “It was a bit like put up or shut up.”

If you’re fighting cancer, a healthy lifestyle can help you stay well during and after treatment. Research suggests that good nutrition, exercise and other healthy behaviors may improve your quality of life during treatment.

“Taking charge of your health by developing healthy habits empowers you to cope better with your treatment and any side effects you may have,” says Lonny Yarmus, D.O., a board certified interventional pulmonologist at the Lung Cancer Program at the Sidney Kimmel Comprehensive Cancer Center.

Patients who come to any Northwestern Medicine location for colonoscopies now have access to advanced artificial intelligence (AI) technology, which is improving the way gastroenterologists detect colon polyps and prevent colorectal cancer. According to new research by Northwestern Medicine, physicians who performed colonoscopies assisted by AI achieved a 13% increase in the detection and removal of colorectal polyps.

Computer-aided colonoscopies could reduce future colon cancer diagnoses by up to 39%.

“Most polyps do not become cancerous, but nearly all colorectal cancers begin as polyps,” says Rajesh N. Keswani, MD, MS, director of Endoscopy for Northwestern Memorial Hospital and director of quality for the Northwestern Medicine Digestive Health Center. “We want to detect them in their earliest stages and remove them to prevent future diagnoses of cancer. There’s nothing better than telling a patient that their decision to have a screening colonoscopy may have saved their life.”

To understand the main determinants behind worldwide antibiotic resistance dynamics, scientists from the Institut Pasteur, Inserm, Université de Versailles Saint-Quentin-en-Yvelines and Université Paris-Saclay developed a statistical model based on a large-scale spatial-temporal analysis. Using the ATLAS antimicrobial resistance surveillance database, the model revealed significant differences in trends and associated factors depending on bacterial species and resistance to certain antibiotics.

For example, countries with high quality health systems were associated with low levels of among all the investigated, while high temperatures were associated with high levels of antibiotic in Enterobacteriaceae. Surprisingly, national antibiotic consumption levels were not correlated with resistance for the majority of the bacteria tested. The results suggest that antibiotic resistance control measures need to be adapted to the local context and to targeted bacteria-antibiotic combinations.

The results of the study were published in the journal The Lancet Planetary Health.

The digital devices that we rely on so heavily in our day-to-day and professional lives today—smartphones, tablets, laptops, fitness trackers, etc.—use traditional computational technology. Traditional computers rely on a series of mathematical equations that use electrical impulses to encode information in a binary system of 1s and 0s. This information is transmitted through quantitative measurements called “bits.”

Unlike traditional computing, quantum computing relies on the principles of quantum theory, which address principles of matter and energy on an atomic and subatomic scale. With quantum computing, equations are no longer limited to 1s and 0s, but instead can transmit information in which particles exist in both states, the 1 and the 0, at the same time.

Quantum computing measures electrons or photons. These subatomic particles are known as quantum bits, or ” qubits.” The more qubits are used in a computational exercise, the more exponentially powerful the scope of the computation can be. Quantum computing has the potential to solve equations in a matter of minutes that would take traditional computers tens of thousands of years to work out.

Reviews:
“This movie hits home since my dad died of cancer when I was 13 and it upsets me tremendously to think that our overall health care system has been corrupted due to the profit system. The Hippocratic oath seems to be more focused on maintaining the status quo of profit versus curing medical problems.

The Movie: An insider’s account from the 70’s at a well known NYC cancer research hospital exposing the truth (using the hospital’s own records) behind how the profit system has corrupted the search for finding a “cure” for cancer. A promising treatment was swept under the rug and the scientist who found it (co-founder of chemotherapy) was forced to lie about his treatment. The treatment was not the “cure”, but it worked remarkably well and very cheap. The problem was it was “very cheap”. Even though the movie is centered around 1 character and it’s almost entirely a narrative, the topic and the evidence is so damning, it’s exciting. It’s a knock-out punch guilty as charged for the hospital. Definitely recommended to all.”

Researchers from the University of California, San Francisco and colleagues conducted a study to determine whether AKI is independently associated with subsequent kidney function trajectory among patients with chronic kidney disease (CKD). The findings suggest kidney disease observed after AKI often present before injury.

In the present study of hospitalized persons with chronic kidney disease (CKD) fournd that acute kidney injury (AKI) did not predict worsening of kidney function trajectory once difference in pre-hospitalization characteristically were fully accounted for. Instead, the authors suggest that much of determinants of faster kidney disease decline observed after AKI may already be present before AKI. The findings are published in Annals of Internal Medicine.

Many now believe that AKI is an independent risk factor for accelerated loss of kidney function. This has led to changes in research focus, practice patterns, and public health targets. However, prior studies associating AKI with more rapid subsequent loss of kidney function had methodological limitations, including inadequate control for differences between patients who had AKI and those who did not.

4. Embrace Decentralized Solutions: Start exploring decentralized technologies like blockchain and decentralized storage solutions. Understand how they can empower you as the custodian of your data by reducing reliance on third-party intermediaries. Research and adopt decentralized platforms that align with your data ownership goals.

5. Stay Informed About Tokenization: Familiarize yourself with the concept of tokenization and how it can impact data ownership. Learn about the potential benefits and risks of tokenizing your data, and evaluate whether it aligns with your objectives. Stay updated on emerging tokenization platforms or data marketplaces that offer opportunities to securely monetize or share your data.

The road to personal data ownership is a bold, significant step forward, but it represents a necessary departure from the status quo. As we move toward a future powered by data-driven insights, the empowerment of individuals as the gatekeepers of their digital selves will become increasingly important to balance the scales between privacy and progress.
