Here’s a valid excuse to ditch that baby shower by text: chinwagging on a mobile phone may be related to higher risk factors for cancer, according to a new study at Tel Aviv University. By looking at the saliva of phone users who chinwagged for eight to 40 hours a month – the salivary gland is in your smartphone’s firing line – researchers found that the saliva of heavy users indicated higher oxidative stress than that of those who either didn’t own a mobile or used it only for texting. While there was no proven cause and effect, experts said it added weight to evidence that long-term phone use could cause harm.
BETCHA DIDN’T KNOW THAT NOT ALL MIGRAINES ARE CREATED EQUAL. ‘MIGRAINE WITH AURA’ IS THE LESS COMMON STRAIN MARKED BY SYMPTOMS SUCH AS ZIG-ZAG PATTERNS AND BLIND SPOTS BEFORE HEADACHE ONSET, WHILE IN ‘MIGRAINE WITHOUT AURA’, THE HEADACHE HITS FIRST. BOTH ARE SUBJECTS OF A BREAKTHROUGH STUDY FINDING THAT SUFFERERS ARE MORE LIKELY TO HAVE AN INCOMPLETE NETWORK OF ARTERIES, KNOWN AS THE CIRCLE OF WILLIS SUPPLYING BLOOD FLOW TO THE BRAIN ACCORDING TO UNIVERSITY OF PENNSYLVANIA RESEARCHERS, AURA SUFFERERS WERE MORE THAN 20 PER CENT MORE LIKELY THAN NON-HEADACHE SUFFERERS TO HAVE AN INCOMPLETE CIRCLE OF WILLIS, WHILE NON-AURA SUFFERERS WERE MORE THAN 10 PER CENT MORE LIKELY TO HAVE ABNORMAL BLOOD FLOW.
The height increment associated with a 13 per cent increase in cancer risk in new research. In a study of more than 20,000 postmenopausal women, greater height was linked to cancers of the breast, colon, endometrium, kidney, ovary, rectum and thyroid, and melanoma, academics reported in Cancer Epidemiology, Biomarkers & Prevention. More cancers were associated with height than with body mass index (BMI). Theory goes that hormones and growth factors affecting height could also impact the risk of cancer, which is also associated with growth.

BAD MOON RISING
Can’t sleep when the moon’s full? You’re not going mad (well, not necessarily). Despite McMansions with block out blinds, humans may still be sensitive to the moons circa lunar clock, suggests a report published in Current Biology. In a study at a US psychiatric hospital, brain activity related to deep sleep plunged 30 per cent around a full moon. The study investigated brain activity, eye movements and hormone secretions. Subjects also got 20 minutes less shut eye, took five minutes longer to doze off and had lower levels of sleep wake hormone melatonin, researchers found.
CHRONIC FATIGUE DRUG HOPE
A new link between chronic fatigue syndrome (CFS) and reactivation of a virus that infects over 95 per cent of people by the age of three could shed light on drug therapies for the condition denoted by long-term fatigue and chronic pain, new research suggests. An article published in the Journal of Medical Virology says some CFS sufferers may lack the immune capacity to keep the HHV-6 virus inactive.
28 THE NUMBER OF CUPS OF COFFEE SHOWN TO STATISTICALLY INCREASE MORTALITY IN WOMEN FEWER THAN 55 BY 50 PER CENT IN NEW US RESEARCH. IN A STUDY OF 45,000 PEOPLE AGED 20 TO 87, YOUNGER WOMEN WHO CONSUMED MORE THAN 28 CUPS OF COFFEE PER WEEK ALSO HAD MORE THAN TWICE THE RISK OF ALLCAUSE MORTALITY THAN LATTE-TOTALLERS. TOO MUCH CAFFEINE CAN INHIBIT INSULIN ACTIVITY AND INCREASE BLOOD PRESSURE, AMONG OTHER PITFALLS
