Explainer: Femtoseconds And Attoseconds

Back in the first half of the 20th century, when MIT’s famed Harold “Doc” Edgerton was perfecting his system for capturing fast-moving events on film, the ability to observe changes […]

Explainer: The Higgs Boson Particle

Theoretical physics is full of mysteries and unknowns. In the case of some particles, we can predict their existence even if we can’t find them. Such is the status of […]

Explainer: The Elusive Neutrino

Of all the known particles in our universe, neutrinos are perhaps the most elusive; their origins are mysterious, their purpose unknown and they are notoriously difficult to detect. You’ll already […]

Acne Cysts and Treatment

Deep cysts, inflammation, extensive damage to the skin and scarring distinguish severe acne. It often requires a hard-hitting treatment regimen and should be treated by a dermatologist.

Severe forms of acne can require years of treatment and may experience one or more treatment failures. However, almost every case of acne can be successfully treated.

There are five popular treatments for acne cysts. There are many effective treatments that are available currently. Drainage and surgical excision, inner lesion corticosteroid injection, isotretinoin (a potent drug for treating severe cystic acne), oral antibiotics, and oral contraceptives are the most popular treatments. Some people may choose a more natural treatment for severe acne, which will also be covered briefly in this article.

Diastolic Blood Pressure

When the heart is at rest, between beats, your blood pressure falls. This is the diastolic pressure. Blood pressure is always given as two numbers, the systolic and diastolic pressures. Both are important. The systolic pressure is the first or top number, and the diastolic pressure is the second or bottom number (for example, 120/80). If your blood pressure is 120/80, you say that it is “120 over 80”.

Both of these numbers do not need to be high for you to have high blood pressure. Either one or both can be high for you to have high blood pressure.

The diastolic blood pressure has been and remains, especially for younger people, an important hypertension number.

Research has shown that higher diastolic blood pressure is a significant risk factor for heart attacks, strokes, kidney failure, and other serious conditions.

As people become older, especially after the age of 55, the diastolic pressure will begin to decrease, while the systolic blood pressure usually begins to rise and becomes more important.

A rise in systolic blood pressure will also increase the chance for heart attacks, strokes, kidney failure, and other serious conditions.


Male & Female Intelligence Brain Areas Differ

Although there are virtually no disparities in general intelligence between the sexes, a UC Irvine study has found significant differences in brain areas where males and females manifest their intelligence. […]
