One in five young people lose sleep over social media

1 in 5 young people regularly wake up in the night to send or check messages on social media, according to new research. This night-time activity is making teenagers three times more likely to feel constantly tired at school than their peers who do not log on at night, and could be affecting their happiness and wellbeing according to Science daily.

Over 900 pupils, aged between 12-15 years, were recruited and asked to complete a questionnaire about how often they woke up at night to use social media and times of going to bed and waking. They were also asked about how happy they were with various aspects of their life including school life, friendships and appearance.

Aspirin slows spread of colon, pancreatic cancer in tumor cells

Researchers have found that aspirin may slow the spread of some types of colon and pancreatic cancer cells according to Science daily.

Platelets are blood cells involved with clotting. They promote the growth of cancerous cells by releasing growth factors and increasing the response of certain proteins that regulate tumor cell development (oncoproteins). Low doses of aspirin, an anti-platelet drug, have been shown to reduce the risk of some types of gastrointestinal cancers, but the process by which aspirin hampers tumor growth has been unclear.

Weather's not to blame for your aches and pains

New research has revealed the weather plays no part in the symptoms associated with either back pain or osteoarthritis according to Science daily.

It's long been thought episodes of both back pain and arthritis can be triggered by changes in the weather, including temperature, humidity, air pressure, wind direction and precipitation.

Professor Chris Maher said: "The belief that pain and inclement weather are linked dates back to Roman times. But our research suggests this belief may be based on the fact that people recall events that confirm their pre-existing views.

Harmful effects of secondhand smoke even before pregnancy

Exposure to second-hand tobacco smoke -- even before conception -- appears to have a lingering impact that can later impair the brain development of a fetus according to Science daily.

Using rats in experiments carefully designed to mimic the second-hand smoke exposures that humans encounter, the researchers found that the chemical components of tobacco smoke affect fetal brain development throughout pregnancy.

The smoke exposure damages regions of the brain involved in learning, memory and emotional responses. Although the impact was most severe with exposures occurring in late gestation, adverse effects on the fetuses' neuro-development occurred even when the mothers were only exposed prior to conception.

"This finding has important implications for public health, because it reinforces the need to avoid secondhand smoke exposure not only during pregnancy, but also in the period prior to conception, or generally for women of childbearing age," said Theodore A. Slotkin, Ph.D.

Slotkin and colleague simulated secondhand smoke exposure by capturing and extracting the chemical compounds of tobacco smoke and administering the solution through implanted pumps in the laboratory animals.

"The current study was designed to determine the effect of inhibition of platelet activation and function by aspirin therapy on colon and pancreatic cancer cell proliferation," the researchers wrote.
