Uniting for a Cure: How Local Leaders, Businesses, and the Community Are Teaming Up to Fight Breast Cancer

  When a community bands together, powerful things happen. Across our neighborhoods, a transformative movement is taking root as local leaders, business owners, and everyday residents join forces to tackle breast cancer head-on. This isn't just about awareness—it’s about direct action, early detection, resource sharing, and building an unbreakable safety net for patients and survivors. The Power of Local Collaboration The fight against breast cancer can often feel overwhelming when faced alone. However, when local ecosystems mobilize, the impact scales rapidly. Municipal leaders, corporate partners, and grassroots volunteers are creating an integrated support framework that turns passive awareness into active, life-saving change. What Local Businesses Are Doing Local enterprises are moving beyond traditional corporate social responsibility (CSR) to become active hubs of health advocacy: Sponsorship and Fundraising: Small and medium-sized businesses are hosting charity sales, round...

Custom, 3D-Printed Heart Replicas Look and Pump Just Like the Real Thing

Source : slashdot.org
MIT engineers are hoping to help doctors tailor treatments to patients' specific heart form and function, with a custom robotic heart. MIT News reports: The team has developed a procedure to 3D print a soft and flexible replica of a patient's heart. They can then control the replica's action to mimic that patient's blood-pumping ability. The procedure involves first converting medical images of a patient's heart into a three-dimensional computer model, which the researchers can then 3D print using a polymer-based ink. The result is a soft, flexible shell in the exact shape of the patient's own heart. The team can also use this approach to print a patient's aorta -- the major artery that carries blood out of the heart to the rest of the body. To mimic the heart's pumping action, the team has fabricated sleeves similar to blood pressure cuffs that wrap around a printed heart and aorta. The underside of each sleeve resembles precisely patterned bubble wrap. When the sleeve is connected to a pneumatic system, researchers can tune the outflowing air to rhythmically inflate the sleeve's bubbles and contract the heart, mimicking its pumping action. The researchers can also inflate a separate sleeve surrounding a printed aorta to constrict the vessel. This constriction, they say, can be tuned to mimic aortic stenosis -- a condition in which the aortic valve narrows, causing the heart to work harder to force blood through the body. Doctors commonly treat aortic stenosis by surgically implanting a synthetic valve designed to widen the aorta's natural valve. In the future, the team says that doctors could potentially use their new procedure to first print a patient's heart and aorta, then implant a variety of valves into the printed model to see which design results in the best function and fit for that particular patient. The heart replicas could also be used by research labs and the medical device industry as realistic platforms for testing therapies for various types of heart disease. The report has been published in the journal Science Robotics.

Foods you should avoid eating before a workout

Dietitians advise that you eat a snack at least thirty minutes prior to any workout. The ideal pre-workout snack contains both protein and carbohydrates to give you the energy you need and the muscle support to last your full session. Some examples of good pre-workout snacks are a slice of toast with peanut butter, oatmeal with half a banana, or some fruit and crackers. But if you ingest the wrong thing, you could be setting yourself up for an unproductive and, frankly, painful experience once you get to your workout. Trust us, you want to avoid these foods if you're planning to work out. Alcohol If you're going to the gym after work, maybe just sip some water during happy hour. And if you're already feeling intoxicated you should probably just skip your workout entirely. Seriously, don't pregame for the gym. Alcohol is a diuretic, meaning that it can make you really dehydrated. Almonds Almonds are high in fat, which is actually the ...
