Reliable carbon-free power for the world — michelle catts, senior vice president, nuclear programs, ge-hitachi nuclear energy.


Michelle Catts is the Senior Vice President of Nuclear Programs at GE-Hitachi (GEH — https://nuclear.gepower.com/) located in Wilmington, NC.

Ms. Catts has over 18 years of demonstrated managerial and technical expertise in nuclear Regulatory Affairs and currently is responsible for ensuring world-class Quality, Continuous Improvement, Regulatory Affairs, and oversight of Environment, Health & Safety programs. She manages a multimillion-dollar budget and over a 30-member organization. She provides licensing and quality leadership and guidance to support nuclear fuel facility licensing, current nuclear fleet fuel reload/outage licensing activities, new reactor and new fuel opportunities, Technical Regulations and Standards, and GE-Hitachis’s Vallecitos and Morris sites.

Prior to joining GE-Hitachi, Ms. Catts worked for the U.S. Nuclear Regulatory Commission (NRC) where she held positions of increasing responsibility including as a nuclear reactor inspector stationed onsite at nuclear power plants up to the Policy Advisor to the Presidential Appointed NRC Chairman.

Ms. Catts holds a B.S. in Nuclear Engineering from North Carolina State University and is currently working on her MBA at UNCW.

The machines could help to “drastically increase the efficiency of the farming industry.”

In farming, weeds can strangle crops and destroy yields. Unfortunately, spraying herbicides to deal with the intrusive plants pollutes the environment and harms human health and there simply aren’t enough workers to tackle all the weeds by hand.

A new startup called FarmWise has come up with a solution: autonomous weeding robots that use artificial intelligence to cut out weeds while leaving crops untouched, according to an MIT report published on Thursday.

A new paper in Nature Communications illuminates how a previously poorly understood enzyme works in the cell. Many diseases are tied to chronic cellular stress, and UMBC’s Aaron T. Smith and colleagues discovered that this enzyme plays an important role in the cellular stress response. Better understanding how this enzyme functions and is controlled could lead to the discovery of new therapeutic targets for these diseases.

The enzyme is named ATE1, and it belongs to a family of enzymes called arginyl-tRNA transferases. These enzymes add arginine (an amino acid) to proteins, which often flags the proteins for destruction in the cell. Destroying proteins that are misfolded, often as a result of cellular stress, is important to prevent those proteins from wreaking havoc with cellular function. An accumulation of malfunctioning proteins can cause serious problems in the body, leading to diseases like Alzheimer’s or cancer, so being able to get rid of these proteins efficiently is key to long-term health.

The new paper demonstrates that ATE1 binds to clusters of iron and sulfur ions, and that the enzyme’s activity increases two-to three-fold when it is bound to one of these iron-sulfur clusters. What’s more, when the researchers blocked cells’ ability to produce the clusters, ATE1 activity decreased dramatically. They also found that ATE1 is highly sensitive to oxygen, which they believe relates to its role in moderating the cell’s stress response through a process known as .

A pilot trial by investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham health care system, tested the nasal administration of the drug Foralumab, an anti-CD3 monoclonal antibody. Investigators found evidence that the drug dampened the inflammatory T cell response and decreased lung inflammation in patients with COVID-19. Further analysis showed the same gene expression modulation in patients with multiple sclerosis, who experienced decreased brain inflammation, suggesting that Foralumab could be used to treat other diseases. Their results are published in the Proceedings of the National Academy of Sciences.

“We discovered a way to shut down inflammation not only seen in COVID-19, but also in a patient with multiple sclerosis as well as in healthy patients,” said lead author Thais Moreira, Ph.D., an assistant scientist at the Ann Romney Center for Neurologic Diseases at BWH and an instructor in Neurology at Harvard Medical School. “This is very exciting because not only does our study suggest that this new monoclonal antibody drug is safe and can modulate the without major side effects, but it can also decrease inflammation in multiple realms, so it may be useful for treating other diseases.”

“Inflammation is a major cause of many diseases,” said senior author Howard Weiner, MD, founder and director of the Brigham Multiple Sclerosis Center and co-director of the Ann Romney Center for Neurologic Diseases. “Our center has spent decades looking for novel ways to treat disease where there is abnormal inflammation in a way that is safe and effective.”

The health of the heart and blood vessels is vital to body function. Early screening can help people understand their risks and potentially prevent adverse health outcomes.

Testing cholesterol levels is important, but another test can further help identify the risk for cardiovascular disease: apolipoprotein B-100 (ApoB) levels. This protein helps transport cholesterol throughout the body.

Testing for the level of this protein in the blood may help identify people who are more at risk for cardiovascular disease, even when cholesterol levels are normal.

The FBI is investigating a data breach affecting U.S. House of Representatives members and staff after their account and sensitive personal information was stolen from DC Health Link’s servers.

DC Health Link is the organization that administers the health care plans of U.S. House members, their staff, and their families.

Impacted individuals were notified today of the breach in an email from Catherine L. Szpindor, the U.S. House Chief Administrative Officer, as first reported by DailyCaller.

With the rapid development of chatbots and other AI systems, questions about whether they will ever gain true understanding, become conscious, or even develop a feeling agency have become more pressing. When it comes to making sense of these qualities in humans, our ability for counterfactual thinking is key. The existence of alternative worlds where things happen differently, however, is not just an exercise in imagination – it’s a key prediction of quantum mechanics. Perhaps our brains are able to ponder how things could have been because in essence they are quantum computers, accessing information from alternative worlds, argues Tim Palmer.

Ask a chatbot “How many prime numbers are there?” and it will surely tell you that there are an infinite number. Ask the chatbot “How do we know?” and it will reply that there are many ways to show this, the original going back to the mathematician Euclid of ancient Greece. Ask the chatbot to describe Euclid’s proof and it will answer correctly [ii]. [ii.

Of course, the chatbot has got all this information from the internet. Additional software in the computer can check that each of the steps in Euclid’s proof is valid and hence can confirm that the proof is a good one. But the computer doesn’t understand the proof. Understanding is a kind of Aha! moment, when you see why the proof works, and why it wouldn’t work if a minor element in it was different (for example the proof in the footnotes doesn’t work if any number but 1 is added when creating the number Q). Chatbots don’t have Aha! moments, but we do. Why?

Giving FemTech its own name helped the community of people working in the sector to find each other, but also gave investors reassurance about where they were putting their money, Tin said.

“It’s a little easier to say you’re invested in FemTech than, you know, a company that helps women not pee their pants … It kind of bridged the gap over to men as well, which was important, still is important, because so many investors are men.”
