Your Heartbeat Isn't Steady, and That's Good

September 23, 2014 7:00 am | by Caltech | News | Comments

Although the heart beats out a very familiar "lub-dub" pattern that speeds up or slows down as our activity increases or decreases, the pattern itself isn't as regular as you might think. In fact, the amount of time between heartbeats can vary even at a "constant" heart rate— and that variability, doctors have found, is a good thing.

Roasted Peanuts Are More Dangerous than Raw

September 23, 2014 7:00 am | by Univ. of Oxford | News | Comments

Dry roasted peanuts are more likely to trigger an allergic reaction than raw peanuts, suggests a study involving mice. The researchers say that specific chemical changes caused by the high temperatures of the dry roasting process are recognized by the body's immune system, “priming” the body to set off an allergic immune response the next time it sees any peanuts.

Chip Holds Promise for Tumor Research

September 22, 2014 2:00 pm | by Purdue Univ. | News | Comments

Amid criticism that the world still is not acting fast enough against the surging Ebola epidemic, Pres. Obama travels today to the CDC to discuss the outbreak with health officials who've been there.

ADHD Brain Study Finds Slower Development of Key Connections

September 16, 2014 7:00 am | by Univ. of Michigan Medical School | News | Comments

A peek inside the brains of more than 750 children and teens has revealed a key difference in brain architecture between those with attention deficit hyperactivity disorder and those without.

Sugars Can Promote, Inhibit Cancer Depending Upon Stage

September 16, 2014 7:00 am | by UC San Diego School of Medicine | News | Comments

During cancer development, tumor cells decorate their surfaces with sugar compounds called glycans that are different from those found on normal, healthy cells. New research has found that sialic acids at the tips of these cancer cell glycans are capable of engaging with immune system cells and changing the latter’s response to the tumor– for good and bad.
