For the first time, scientists have been able to produce kangaroo embryos through in-vitro fertilization (IVF), an important milestone in being able to replicate this across hundreds of species of pouch-toting marsupials under ever-increasing threat of extinction.A team from the University of Queensland successfully replicated nature from eggs and sperm harvested from eastern grey kangaroos (Macropus giganteus), but not because of their own threat of extinction. The animals actually number in their millions and are adept survivors. However, many of their marsupial relatives are not as fortunate, and due to habitat loss, the development of roads, heat stress and invasive…

Dairy cows in Nevada have been infected with a new form of bird flu that is distinct from the version that has been spreading through herds over the last year, the U.S. Department of Agriculture announced on Wednesday.The finding indicates that the virus, known as H5N1, has spilled from birds into cows at least twice — leading to these two sets of infections — and that it could continue to do so. It also suggests that the virus may pose a persistent risk to cows and to the people who work closely with them.Before last year, scientists did not know…

Whether you’re starting your fitness journey or are a seasoned gym rat, you’ve probably come across pre-workout. The strongest pre-workouts stand out from the pack because they are formulated with scientifically backed ingredients and doses to enhance your physical and mental performance. “How strong a pre-workout is depends on the compounds it has that stimulate the central nervous system, which helps increase energy and wakefulness,” says Alex Oskian, M.S., R.D.N. As a certified personal trainer, when I’m looking for the strongest pre-workout, I make sure it has four key ingredients: caffeine (at least 200mg), L-citrulline (at least 4,000mg), beta-alanine (at…

The evolution of the Octo carabiner multitool is an unusual one. The device started small, got bigger, but has now shrunk again. That small-again model, called the Octo Mighty, still manages to pack 18(ish) functions into a li’l titanium body.Manufactured by Danish outdoor gear company Sitpack, the original Octo – which you can still buy – is a multi-functional carabiner offered in metal choices of titanium, stainless steel or aluminum. Among other things, it sports a fold-out magnetic bit driver, bottle opener/pry bar, and wire stripper.It was followed up by the bigger and beefier Octo Max, which adds some more…

Are vegetable and seed oils “toxic”?! From TikTok to bestseller lists, vegetable oils—a.k.a. “seed oils”—are a big topic right now. To be fair, folks have debated the merits of vegetable oils dating back to when they first entered the marketplace. More recently, however, with the advent of the carnivore diet, vegetable oil hate has roared back into the socials. Maybe you’ve come across posts that refer to these cooking oils as “toxic sludge,” “motor oil,” “the hateful eight,” and “the biggest cause of chronic disease that nobody knows about.” The anti-vegetable oil logic goes something like this… Animal fats have…

This is just all kinds of outrageous. Last November, a skydiver jumped out of a helicopter, glided down into the Grand Canyon wearing a wingsuit, turned around to face the sky, and hooked up to a plane flying above him so it could tow him up and away into the air.That’s the world’s first mid-air plane hook maneuver – and a testament to skydiver Max Manow’s ambition to push the boundaries of extreme aerial sports.You can watch the stunt below in a freshly minted video, and get a glimpse behind the scenes at the meticulous preparation and planning that went…

Once upon a time, I invested in a cottage cheese brand because it was delicious and reminded me of my childhood. I’m still grateful to this day that I did because I love it and it’s encouraged me to use cottage cheese more creatively. Sure, I like it on its own, but it turns out that it’s so much more versatile than I ever thought.  I’ve now used cottage cheese in everything from crepes, to cheesecake, to queso, and so much more. I have some friends who love buffalo chicken wings, and this experimentation was for a party dip and…

When someone says they want to lose weight, what they really mean is they want to shed excess body fat. However, without a well-designed plan in place, a calorie deficit leads you to lose both fat and valuable muscle tissue. To minimize muscle loss, it’s crucial to incorporate resistance training, quality sleep, and a high-protein diet into your regular routine. Protein plays a multifaceted role in weight management, influencing factors like hunger levels, metabolism, and muscle preservation. While heavy resistance training provides the necessary stimulus, signaling to the body that existing muscle should be retained, a high-protein diet ensures the body has an ample…

eFoiling should be getting a whole lot easier yet also more exciting, according to Lift Foils. The Puerto Rican company has announced its new Lift5 and LiftX boards, which are reportedly both quicker to assemble and more capable than their predecessors.Should you be unfamiliar with eFoils, they typically take the form of what is basically a surfboard with a streamlined mast extending down from the underside, in the rear. At the bottom of that mast is a foiling wing and a motor/propeller module.The board starts out floating flush with the water’s surface, but rises up out of the water as…

Q: Sometimes I feel really anxious the day after I drink. Can alcohol cause a panic attack?The short answer is yes.Panic attacks — sudden waves of overwhelming fear and apprehension, along with physical symptoms like chest pain and tightness, sweating, a racing heartbeat, nausea, difficulty breathing, feeling faint or numbness in the arms and hands — are intense episodes of anxiety.And alcohol and anxiety are considered “two sides of the same coin,” said Dr. Alëna Balasanova, an associate professor of psychiatry and the director of addiction psychiatry education at the University of Nebraska Medical Center.While drinking is often used as…
