“The bottom-line finding is that cannabis before exercise seems to increase positive mood and enjoyment during exercise, whether you use THC or CBD. But THC products specifically may make exercise feel more effortful,” said Dr. Laurel Gibson.

How does cannabis influence workouts? Does it serve as a performance enhancer or in other ways? This is what a recent study published in Sports Medicine hopes to address, as a team of researchers from the University of Colorado Boulder (CU Boulder) and the University of Colorado Anschutz Medical Campus investigated how cannabis influences exercise workouts and regimens, specifically pertaining to the exercise performance. This study comes almost a decade since Colorado legalized the sale of recreational marijuana and holds the potential to help researchers and the public better understand cannabis’ role in our everyday lives.

For the first-of-its-kind study that started in 2021, the researchers recruited 42 participants who were consistent cannabis users ages 21 to 39 to ascertain their responses to exercise after using cannabis and in a controlled laboratory setting. In the end, the participants reported increased enjoyment and “runner’s high” characteristics while also reporting greater levels of exertion during their exercise regimen. Additionally, the participants reported the following when the researchers asked them why they combine cannabis with their workout routines: 90.5 percent said it increases enjoyment, 69 percent said it reduces pain, 59.5 percent said it increases focus, 57.1 percent said it increases motivation, 45.2 percent stated they perceived that it speeds up time, and 28.6 percent said it improves their performance.

Cancer and an enlarged prostate cause similar symptoms, so it’s important to understand the differences.

Fresh from announcing positive Phase 1 trial results for its inflammation-targeting drug candidate, Utah-based biotech Halia Therapeutics is now pursuing Phase 2 studies in a range of indications. The Salt Lake City company’s lead compound is an inhibitor of the NLRP3 inflammasome, a known driver of systemic chronic inflammation, which is linked to conditions including fibrotic disease, Alzheimer’s, Parkinson’s and many others.

Halia is taking a unique approach to the NLRP3 inflammasome by targeting the protein NEK7, which plays a key role in gene’s activity. In preclinical models, the company has shown its approach disrupts the formation of the NLRP3 inflammasome and promotes its disassembly once activated, reducing the overall inflammatory response. In its recent Phase 1 trial, in addition to showing positive safety and tolerability data, Halia’s drug demonstrated positive effects in blood samples taken from healthy volunteers, showing “over 90% suppression of multiple NLRP3-mediated cytokines and chemokines.”

Longevity. Technology: Chronic inflammation is a frequent topic of discussion in longevity circles. The term “inflammaging” refers to the increase of inflammatory cytokines in our bodies as we age, which is linked to chronic morbidity, disability, frailty and premature death. While there is no doubt that Halia believes that its approach can potentially impact many diseases, does the company have aging itself in its sights? We caught up with CEO Dr David Bearss to find out.

Have you heard of (MTC)? While ThyroidCancer is fairly common, there are four different types of thyroid cancers and MTC is the rarest type making up 3% of 4% of all thyroid cancers. Check out our expert reviewed summary for more.

Medullary thyroid cancer, or MTC, is a cancer that forms in the thyroid. The thyroid is a gland located in the front of your neck, just below the Adam’s apple. It is responsible for sending out hormones to the rest of your body. The inside of the thyroid is called the medulla. The medulla contains special cells called parafollicular C cells that produce and release hormones. MTC happens when the C cells become cancerous and grow out of control. MTC may also be called medullary thyroid carcinoma.

How common is medullary thyroid cancer?

As the average lifespan of people with Down Syndrome (DS) has more than doubled over the past 40 years, more people with DS are being considered for total hip and knee replacements.

Patients with Down syndrome are not more likely to need follow-up surgery after a total knee replacement or total hip replacement. But they are at higher risk.

MSU researcher Carolina de Aguiar Ferreira is changing the way we fight cancer. She is precisely targeting cancer cells with diagnostics and therapies using radioisotopes produced by FRIB, the world’s most powerful heavy-ion accelerator.

Using breakthrough tools to target cancer led Carolina de Aguiar Ferreira to MSU, where she found a community of scientists who discover better together.

Restricting calories is known to improve health and increase lifespan, but much of how it does so remains a mystery, especially in regard to how it protects the brain. Buck Institute for Research on Aging scientists have uncovered a role for a gene called OXR1 that is necessary for the lifespan extension seen with dietary restriction and is essential for healthy brain aging.

“When people restrict the amount of food that they eat, they typically think it might affect their digestive tract or fat buildup, but not necessarily about how it affects the brain,” said Kenneth Wilson, Ph.D., Buck postdoc and first author of the study, published in Nature Communications. “As it turns out, this is a gene that is important in the brain.”

The team additionally demonstrated a detailed cellular mechanism of how dietary restriction can delay aging and slow the progression of neurodegenerative diseases. The work, done in fruit flies and human cells, also identifies potential therapeutic targets to slow aging and age-related neurodegenerative diseases.

Part 2: This is the second of a three-part series on how Stanford Medicine researchers are designing vaccines that protect people from not merely individual viral strains but broad ranges of them. The ultimate goal: a vaccine with coverage so broad it can protect against viruses never before encountered.

The series opener focused on why having vaccines that cover not just one strain of a single virus, but many, could be an invaluable advance. Although Part 1 focused on the COVID-19-causing SARS-CoV-2 as a textbook example, that strain-spewing microbe is just one of many viruses to worry about.

Take, for instance, the old steady: influenza.

Artificial intelligence has progressed from sci-fi fantasy to mainstream reality. AI now powers online tools from search engines to voice assistants and it is used in everything from medical imaging analysis to autonomous vehicles. But the advance of AI will soon collide with another pressing issue: energy consumption.

Much like cryptocurrencies today, AI risks becoming a target for criticism and regulation based on its high electricity appetite. Partisans are forming into camps, with AI optimists extolling continued progress through more compute power, while pessimists are beginning to portray AI power usage as wasteful and even dangerous. Attacks echo those leveled at crypto mining in recent years. Undoubtedly, there will be further efforts to choke off AI innovation by cutting its energy supply.

The pessimists raise some valid points. Developing ever-more capable AI does require vast computing resources. For example, the amount of compute used to train OpenAI’s ChatGPT-3 reportedly equaled 800 petaflops of processing power—on par with the 20 most powerful supercomputers in the world combined. Similarly, ChatGPT receives somewhere on the order of hundreds of millions of queries each day. Estimates suggest that the electricity required to respond to all these queries might be around 1 GWh daily, enough to power the daily energy consumption of about 33,000 U.S. households. Demand is expected to further increase in the future.
