Frequent fliers prone to radiation poisoning

Experts have warned that long-term radiation poisoning from ‘solar space storms’ or flare activity from the sun can cause severe harm.

Researchers found passengers faced the ‘hazard’ of space radiation, which created unhealthy levels of exposure while flying at ‘typical cruise altitudes’ of 40,000 feet.
NASA scientists believe the earth is facing danger from a once-in-a-century ‘solar flare’, a disturbance on the sun’s surface that could cause geomagnetic storms on this planet.
Scientists from the Rutherford Appleton Laboratory, Oxon found aircrew were ‘the major occupation group’ most exposed to the sun’s radiation with passengers also at risk from the phenomenon.

“There is an increased risk of cancer. People would be sensible to think about kind of work they do, how much flying they do and what risk that poses. I don’t think that is unreasonable,” said Mike Hapgood, the head of the Laboratory’s Space Environment Group. Lloyds of London, the insurance market, published the study.

Laughter can make some snooze 100 times a day

Laughter may be the best medicine, but for some, it’s nothing less than a disorder — a sleep disorder called narcolepsy can send a person into an instant slumber without warning if you laugh.

People with this order suffer temporary muscle weakness when they experience emotions such as surprise, fear and the exhilaration that comes from a good belly laugh.
It usually manifests itself as cataplexy, in which wide-awake sufferers ‘flop’ as if falling into a deep sleep.

“I lost strength in my hands or my head went limp and nodded forward for a few seconds when I laughed,” said Claire Allen, who suffers from the disorder.Claire, from Cambridge, was sometimes collapsing 100 times a day.

The majority of sufferers start experiencing it in their teens or early 20s when the combination of daytime fatigue and night-time insomnia is simply dismissed as adolescent laziness.
“Quality of life can be badly hit if untreated. Their studies suffer. They avoid driving. They are afraid to look after young children on their own and take baths. They don’t get into relationships, get promoted or do physical exercise,” said Dr John Shneerson, an expert at Papworth Hospital’s sleep centre in Cambridge.

Soon, a ‘nano drug’ jab that hits brain tumour’s bullseye

The scientists have developed a unique technology, which can inject anti-tumour drugs directly into brain tumour cells, unlike other drugs of its kind.

The research team at Cedars-Sinai’s Maxine Dunitz Neurosurgical Institute has created a ‘nanobioconjugate’ drug that may be given by intravenous injection and carried in the blood to target the brain tumour.

It is engineered to specifically permeate the tumour cell wall, entering endosomes, mobile compartments within cells.

Studies in lab mice showed this system allows large amounts of antitumor drug to accumulate in tumours, significantly slowing the growth of new vessels and the tumours themselves.

“This nanobioconjugate is different from earlier nanomedicine drugs because it
delivers and releases antitumor drugs within tumour cells, not just at the site of
a tumour,” said research scientist Julia Y Ljubimova, senior author of the
article.
“Based on our studies, this nanoconjugate appears to be a safe and efficient delivery platform that also may be appropriate in the treatment of degenerative brain conditions and a wide array of other disorders,” she added.
