Many common kitchen items like clamshells, foil and greasy pizza boxes often can’t go in curbside recycling.Food residue on containers and mixed materials, like coffee cans, make recycling harder and often contaminate loads.Scrap metal facilities can recycle cookware and appliances, while local stores may accept bags and plastic wrap. Whether you’re trying to eliminate food waste, cut down on single-use plastics or learn to compost, your kitchen is one of the most impactful starting points for being more sustainable at home. This is also the area of the home with the biggest potential for recycling, which most Americans support but…

When dietitians, food scientists and cardiologists all tell you to ditch plastic cutting boards, it’s worth listening to. I communicated with these experts at separate times, asking what they avoid in the kitchen, and the plastic cutting board has come up repeatedly for its microplastics risk. It makes sense: Studies show that over time, after consistent use, you’re essentially cutting little particles of your plastic board right into your food. Yummy!  Because of all of these building insights, I knew that when I moved three months ago, I would take the opportunity to switch to a non-toxic cutting board alternative,…

Scarlett McNally, professorEastbournescarlettmcnally{at}cantab.netFollow Scarlett on X @scarlettmcnallyThere was standing room only in my hospital’s big lecture theatre for a recent seminar about retirement from the NHS. I recognised many staff, now in their 50s and 60s, who I’ve worked alongside for a quarter of a century. It was palpably sad to see the NHS potentially losing so many experienced, wise people who know how things work and hold the collective memory of an organisation. The event felt like a surreal group lifestyle clinic with colleagues,1 and I sensed a cohort limping through their workload, hoping to reduce some heavy financial…

Cell clusters that resemble the uterine lining grow with support cells in a synthetic hydrogel.Credit: Juan Gnecco, Linda G. GriffithIn 2017, Ashley Moffett, a reproductive immunologist, walked to the pharmacy near her laboratory at the University of Cambridge, UK, to buy a pregnancy test. But it wasn’t for Moffett. Her postdoc, Margherita Turco, had created what she thought might be the first cluster of cells capable of mimicking the tissue of the placenta — a placental organoid. But she needed a way to be sure.The new science of menopause: these emerging therapies could change women’s health“We must do a pregnancy…

Not all genetic fusions are created equal. In a new Cancer Discovery study, titled “EML4-ALK variant-specific genetic interactions shape lung tumorigenesis,” scientists from the German Cancer Research Center (DKFZ) and Stanford University reveal that different EML4-ALK fusion variants—the oncogenic drivers behind about 5% of lung adenocarcinomas—behave more like distinct oncogenes. Their findings, uncovered with advanced CRISPR genome editing in mice, could reshape how clinicians classify and treat these tumors. The EML4-ALK fusion occurs when parts of the EML4 and ALK genes break and rejoin, creating an abnormal protein that fuels cancer growth. But the precise breakpoints vary, producing multiple “variants,”…

A high school team sent their science experiment to space for a month.Image credit:©iStock, Elen11It started with a poster on the classroom board of William Heinen, a biology teacher at St. Francis High School in La Cañada Flintridge, California, that called for all students to participate in a competition organized by the school for a once-in-a-lifetime experience. The inaugural Knight Skies Program was created to spark student interest in space science and STEM fields. Spearheaded by space enthusiast and religious studies teacher Mark Fredette, in partnership with Dream Up to Space, the STEM education branch of Voyager Space Explorations, the…

Queen Elizabeth added lemon zest and nutmeg to her scrambled eggs.The combo adds brightness, warmth, and balance to a basic breakfast.This royal twist is easy to try and brings bold flavor with minimal effort. Eggs are a dependable source of protein. They also offer plenty of beneficial nutrients and can be the centerpiece of a truly delicious meal—whether it’s a quiche for brunch or a simple breakfast taco. With so many benefits, it’s no wonder eggs are a popular breakfast food. Still, it’s easy to get into an egg rut, cooking up the same basic scramble every morning. We’re taking…

1. Change Your HabitsIf you feel like your calf muscles are always clenched and tight (which can make them appear swollen), try reminding yourself to relax them while you’re sitting, lying down, or at rest. For some people, wearing certain shoes — like high heels — can cause them to tense their calves all day, leading to swelling and pain, according to a study published in 2022. Opt for supportive, comfortable shoes when possible.Getting physically active each day is also important for toning your calves and entire body. Walking, for example, can help improve blood circulation in the legs, according to the…

Green tea is rich in beneficial plant compounds but sipping on the tea isn’t completely risk-free. Many of the active compounds in green tea interfere with some medications, like blood thinners and stimulants.You may want to limit or avoid green tea if you’re pregnant, caffeine sensitive or have anemia. Since around 3000 BC, people have enjoyed green tea for its many health benefits and its distinctive flavor. In recent years, research has uncovered its supportive connections to weight loss, improved focus, anti-aging effects and cancer prevention. “Green tea is rich in antioxidants and loaded with polyphenols, especially catechins (like EGCG), which…
