For many coffee lovers, making espresso seems to require two essential ingredients: very hot water and high pressure. But researchers at the University of New South Wales (UNSW) in Australia have challenged that assumption by creating espresso-strength coffee using room-temperature water and ultrasonic sound waves. The new technique could reduce the energy needed to make […]

Astronomers have discovered a huge reservoir of cold gas in one of the earliest known galaxies, providing new clues about how some galaxies grew so quickly after the Big Bang. The galaxy, known as REBELS-25, is so far away that astronomers see it as it appeared about 700 million years after the birth of the […]

For many years, doctors have encouraged people with obesity to lose weight in order to improve their heart health. Even modest weight loss can reduce strain on the heart, improve blood sugar levels, and lower blood pressure. Now, a major new study suggests that the latest generation of weight-loss medications may deliver significant blood pressure […]

Millions of older adults worry about losing their strength and independence as they age. Many people fear not only serious illnesses such as heart disease or cancer but also the gradual loss of physical function that can make everyday tasks difficult. This condition, known as frailty, affects a growing number of older people around the […]

For decades, measuring blood pressure has involved the same basic process. A cuff is wrapped around the upper arm, inflated until it squeezes the artery, and then slowly released while measurements are taken. Although this method is widely used and generally reliable, it has one major weakness: it only captures a single reading at one […]

The thyroid gland is small, but it plays a huge role in keeping the body healthy. Located at the front of the neck, this butterfly-shaped gland produces hormones that help control metabolism, energy levels, body temperature, heart rate, growth, and many other important functions. When the thyroid does not work properly, it can affect almost […]
