Garlic isn’t just a kitchen staple—it may also nudge blood pressure down a little when taken as a supplement. Studies using aged garlic extract at 600 mg twice daily showed small drops in readings, but fresh garlic hasn’t been studied as much. The active compound, allicin, works as a mild blood vess
The human brain is wrapped in a tight shield called the blood-brain barrier. Its job is to block harmful stuff while letting in water and nutrients. When this barrier leaks even a little, the brain can get hurt. Scientists want to measure how fast water moves in and out—not to crack the door open, b
Keeping tabs on your health shouldn’t feel like a chore, yet many people overlook something as important as blood pressure. While smartwatches track steps and sleep, measuring blood pressure has been missing from most mobile health tools—until now. A device like the iHealth Track changes that by off
Wearable tech isn’t just for fitness trackers anymore. For people with diabetes, small sensors stuck on the skin now watch blood sugar levels 24/7. These gadgets, called continuous glucose monitors (CGMs), send real-time updates so users know when to adjust diet, exercise, or medication. But do they
A crime scene can hold a bloody fingerprint that helps identify the culprit. The pattern and the DNA in the blood give strong clues to a judge or jury. But sometimes the print is not real. A latent print may already be there, and later blood can make it look like a fresh mark. This is calle
Most people don’t realize how often pets need blood transfusions—just like humans. Yet finding enough pet donors is a constant struggle. Part of the problem is that not enough animal owners know this lifesaving option exists. Veterinarians are in a unique position to change that. They see patients d
Malawi needs more blood than it can collect. Right now, the country has nearly 13% less blood than hospitals require. That gap means doctors sometimes delay surgeries or send families scrambling to find donors in emergencies. Schools could be part of the answer. Teenagers make up a big share of Mala
A study examined how moving into new, well‑insulated apartments with good ventilation affects people’s blood pressure. Researchers measured participants’ BP twice a year for two years before the move and again after they settled in. They tracked morning and evening readings for nearly 180 people eac
A recent study found that drinking watermelon juice every day for two weeks helped young adults keep their heart rate variability stable after consuming a sugary drink. Heart rate variability measures how well the body shifts between stress and relaxation modes. Normally, blood sugar spikes after ea
A new study shows that a simple blood test can flag the risk of Alzheimer’s long before any brain scan or symptoms appear. The test measures a specific form of tau protein called pTau217 in the blood, which has been linked to the toxic tangles that form inside Alzheimer’s brains. Researchers followe
