Using two tactics to retrain his brain, Karp gained confidence and pursued a career in academia. The MIT and Harvard professor shares the benefits of working in a flow state in his new book. Though I still struggle every day in various ways, I'm grateful to be able to say that these LIT tools enabled me to meet and far exceed those dismal early expectations.

In addition to the physical benefits of exercise, it’s also associated with a reduction in stress signals in the brain, which leads to a decreased risk of cardiovascular disease, according to the study. For people without any history of depression, the benefit of exercise on cardiovascular disease reduction plateaued after about 300 minutes of moderate physical activity a week. How it worksExercise reduced stress signals and increased prefrontal cortical signals, Tawakol said. In part, exercise appeared to reduce heart disease risks by reducing the stress signals, Tawakol said. But figure out a way to get a physical activity in that you truly enjoy,” he said.

Some manufacturers say indicator lights can sometimes serve a practical purpose. For example, an indicator light could show that a device is charging or plugged in and working properly. The light has a long lifespan and doesn’t generate excess heat — important qualities for a technology that’s used every day. “As a manufacturer, adding an LED light does cost something, so to add one just to add one seems quite wasteful.

Men had more strokes related to extreme temperatures than women, but it affected people across all age groups. While that may sound counterintuitive for global warming, cold temperatures also come along with climate change. Last year was the warmest since scientists started recording global temperatures in 1850 and temperatures are expected to break more records in the near future. The new study wasn’t designed to show why extreme temperatures that come with the climate crisis seem to be causing so many strokes. Extreme cold temperatures also can lead someone to have a stroke.

Instead, it's about how well you can prioritize your commitments, deadlines, projects and work, says Juliette Han, a Harvard-trained neuroscientist and adjunct professor at Columbia Business School. If you want a second opinion on your job audit, Han suggests consulting either a colleague or your manager. "Tell them you're evaluating your current workload to maximize your productivity and focus on some bigger goals," she says. For example: You might be less responsive to emails, but if you're using that free time on deep-focus work, you're probably turning in better-quality work. "Thinking through all the components of your workload and how these help — or hurt — your career development is super important," Han stresses.

Research has consistently shown that being liked at work can positively influence your career advancement, from negotiating a raise to landing a promotion. Gaining a colleague's respect or making work friends isn't a privilege reserved for high performers, says Juliette Han, a Harvard-trained neuroscientist and adjunct professor at Columbia Business School. According to Han, there's one "cheat code" highly successful people use to form stronger bonds with people at work: They find common ground with the people they work with. "You want to have a clear, open dialogue with the people you work with to show that you listen to and respect their preferences," Han explains. Praising someone on a presentation well done, their work ethic or a skill they've mastered "can go a long way," says Han.

The label expansion may improve insurance coverage for Wegovy, which costs more than $1,300 per month out of pocket before any discounts. Many insurers, including Medicare, don’t cover drugs for weight loss, leaving patients scrambling to afford them. “This patient population has a higher risk of cardiovascular death, heart attack and stroke,” he added. More studies need to be done to show whether there are heart benefits for people who haven’t had a cardiac event.

Speaking up in meetings can be intimidating, especially if you're an introvert — but failing to make your voice heard at important moments could hurt your career. That's at least according to Juliette Han, a Harvard-trained neuroscientist and adjunct professor at Columbia Business School. There's a different "tried and true" trick to standing out at work without speaking up during meetings, says Han, who is also an academic advisor at Harvard medical school. This could include brainstorms, status-update meetings, problem-solving meetings or other important work conversations. Or, if someone posed a potential solution to a business challenge during a meeting, and you would recommend a different approach, outline your thoughts in the follow-up email, says Han.

We discussed that for many people, the most powerful tools for medical weight management are the glucagon like peptide 1 (GLP1) agonists. As of 2024, insurance, not body weight or BMI, has become the most important vital sign for doctors who see patients for medical weight management. They really did transform a fairly barren landscape of pharmacotherapeutic options for medical weight management that lasted several decades. Weight loss is on average about 15% with Wegovy and 22% with Zepbound, with super responders losing more than 25% of their body weight. By comparison, other medications that are FDA-approved for weight loss, including Qsymia and Contrave, are combinations of much older drugs.

CNN —The traditional diet of northern Portugal and northwestern Spain, known as the Southern European Traditional Atlantic Diet, or Atlantic diet for short, may hold some clues to better heart health and a lower risk of dying early from cancer, heart disease or any cause, according to studies conducted in Europe. The diet is based on foods grown or found in that part of the Europe, much like its famous cousin the Mediterranean diet. Because it’s plant-based and locally sourced, the Atlantic diet also helps protect the planet by contributing to the United Nations’ Sustainable Development Goals, the study’s authors noted. Like the Mediterranean diet, the Atlantic diet focuses on home-cooked food served family style, with an emphasis on social interactions between friends and family. However, other studies have shown that not all food groups in the traditional Atlantic diet are beneficial.

Still, the question remains: Does cannabis truly cause psychosis and related diseases such as schizophrenia — or is this another overblown claim? It is especially important for us, as doctors, to untangle whether cannabis actually causes psychosis. Still, of all the drugs associated with this uncommon kind of psychosis, cannabis is the most common culprit. CBD products should only be purchased from reputable companies that test their products through independent labs and share the results. We shouldn’t jump to the conclusion that cannabis causes psychosis, but anyone who plans to use cannabis should know their personal risk factors and exercise caution accordingly.

☆ Researchers think they have the key to why tardigrades can survive almost anything
▼ + stars: | 2024-02-05 | by ( Jenna Schnuer | ) edition.cnn.com time to read: +6 min

CNN —Tardigrades, also known as water bears, commonly survive in some of Earth’s most challenging environments. Under stress in extreme cold or other harsh environmental conditions, tardigrades’ bodies produce unstable free radicals of oxygen and an unpaired electron, aka a reactive oxygen species that can wreak havoc on the body’s proteins and DNA if they overaccumulate. The survival mechanism kicks off when cysteines, one of the amino acids that forms proteins in the body, come into contact with these oxygen free radicals and becomes oxidized, the researchers found. The free radicals become, so to speak, the hammer used to smash the glass on a fire alarm. “We came up with this idea (that) maybe it’s those species that are actually signaling to the tardigrades to enter their tun state,” she said.
