Dr. Natalie Yivgi-Ohana, Ph.D. — CEO, Minovia Therapeutics — Harnessing The Therapeutic Power Of Mitochondria
Is Co-Founder and CEO of Minovia Therapeutics (https://minoviatx.com/), a biotech company dedicated to rapidly advance life-changing therapies that address the unmet need of serious and complex mitochondrial diseases, and are the first clinical-stage company to develop a mitochondrial transplantation approach to treat a broad range of indications generated by a mitochondrial dysfunction which lead to rare-genetic or age-related diseases.
Dr. Yivgi-Ohana has twenty years of experience in mitochondrial research and received her Ph.D. in Biochemistry at The Hebrew University, after which she completed her postdoctoral fellowship at the Weizmann Institute of Science.
Dr. Yivgi-Ohana also has her B.Sc., Medical Sciences Ben-Gurion University of the Negev and her Master’s Degree, Human Reproduction Bar-Ilan University.
Dr. Yivgi-Ohana founded Minovia with a passion to help children and adults with mitochondrial diseases worldwide.
Epic Games & Google Reveal $800 Million Deal Amid Lawsuit
During a recent hearing in San Francisco, Epic’s CEO Tim Sweeney revealed that the agreement is related to Fortnite’s metaverse: “Epic’s technology is used by many companies in the space Google is operating in to train their products, so the ability for Google to use the Unreal Engine more fullsome… sorry, I’m blowing this confidentiality.”
In this partnership, Epic will spend $800 million to buy some unannounced services from Google. However, this is not a joint product made by the companies. “This is Google and Epic each separately building product lines,” Sweeney said.
Sweeney doesn’t see anything wrong with paying Google “to encourage much more robust competition than they’ve allowed in the past,” he said. “We view this as a significant transfer of value from Epic to Google.”
Enzyme as Maxwell’s Demon: Steady-State Deviation from Chemical Equilibrium by Enhanced Enzyme Diffusion
NoteL This is elegant theoretical physics showing an intriguing possibility, not a confirmed biological mechanism. It’s a “what if” scenario that could change how we view enzymes, but only if the controversial premise (EED) turns out to be real.
Enhanced enzyme diffusion (EED), in which the diffusion coefficient of an enzyme transiently increases during catalysis, has been extensively reported experimentally, although its existence remains under debate. In this Letter, we investigate what macroscopic consequences would arise if EED exists. Through numerical simulations and theoretical analysis, we demonstrate that such enzymes can act as Maxwell’s demons: They use their enhanced diffusion as a memory of the previous catalytic reaction, to gain information and drive steady-state chemical concentrations away from chemical equilibrium. Our theoretical analysis identifies the conditions under which this process could operate and discusses its possible biological relevance.
Heisenberg-limited Quantum Sensing Achieves Noise Resilience Via Indefinite-Causal-Order Error Correction
The research extends beyond theoretical analysis by outlining a feasible experimental implementation using integrated photonics. This includes a detailed description of the required optical components and control sequences for realising the ICO gate and performing the quantum sensing measurements. By leveraging the advantages of integrated photonics, the proposed scheme offers a pathway towards compact and scalable quantum sensors with enhanced performance characteristics. The findings pave the way for practical applications in fields such as precision metrology, biomedical imaging, and materials science.
Indefinite Causal Order for Real-Time Error Correction
Realistic noisy devices present significant challenges to quantum technologies. Quantum error correction (QEC) offers a potential solution, but its implementation in quantum sensing is limited by the need for prior noise characterisation, restrictive signal, noise compatibility conditions, and measurement-based syndrome extraction requiring global control. Researchers have now introduced an ICO-based QEC protocol, representing the first application of indefinite causal order (ICO) to QEC. By coherently integrating auxiliary controls and noisy evolution within an indefinite causal order, the resulting noncommutative interference allows an auxiliary system to herald and correct errors in real time.
New Drug Slashes Dangerous Blood Fats by Nearly 40% in First Human Trial
When we eat, the body turns surplus calories into molecules called “triglycerides”, especially when those calories come from carbs, sugar, fats, and alcohol. Triglycerides are a type of fat or “lipid”, and the body stores them in fat cells to use as fuel between meals.
However, too much of this fat can become harmful. High triglyceride levels can lead to “hypertriglyceridemia” (“excess triglycerides in the blood”), a condition tied to a much higher risk of heart disease, stroke, and pancreatitis. That is why people are widely encouraged to support healthy triglyceride levels through diet and exercise, while more severe cases may require medication.
