Cancer cells eat their neighbors' 'words'

Cancer cells are well-known as voracious energy consumers, but even veteran cancer-metabolism researcher Deepak Nagrath was surprised by their latest exploit: Experiments in his lab show that some cancer cells get 30-60 percent of their fuel from eating their neighbors' "words."

"Our original hypothesis was that cancer cells were modifying their metabolism based on communications they were receiving from cells in the micro environment near the tumor," said Nagrath, assistant professor of chemical and biomolecular engineering. "None of us expected to find that they were converting the signals directly into energy."

Targeting cancer’s ‘Achilles heel’ could revolutionize treatment, scientists claim

British scientists have found a ground-breaking technique to attack the ‘Achilles heel’ of cancerous cells, potentially revolutionizing the way the disease is tackled.

The scientists from University College London (UCL) have identified a new approach using the body’s own immune system to wipe out cancer cells, according to RT.

They have discovered rare immune cells which “could form a fearsome cancer fighting force,” according to a video released by Cancer Research UK.

Peanut allergy theory backed up by new research

The effects of eating peanut products as a baby to avoid the risk of allergy have been backed up by new research.

In 2015, a study claimed early exposure to peanut products could cut the risk of allergy by 80% .

Now researchers say "long-lasting" allergy protection can be sustained - even when the snacks are later avoided for a year, according to BBC.

The New England Journal of Medicine study looked at 550 children deemed prone to developing a peanut allergy.

Moments of joy 'can damage heart'

The emotional stress that causes chest pains and breathlessness can occur in moments of joy as well as anger, grief and fear, a Swiss study suggests.

Three-quarters of cases of takotsubo cardiomyopathy, a change in the shape of the heart's left ventricle, which can be fatal, are caused by stress, according to BBC.

The University Hospital Zurich study, in the European Heart Journal, suggests about one in 20 cases is caused by joy.

The condition is normally temporary and people are generally fine afterwards.

Milk teeth reveal medieval children

For modern children used to scoffing handfuls of sugary treats and tasty snacks, the diet of medieval youngsters would have come as something of a shock.

While medieval meals are popularly depicted as banquets with huge haunches of meat, cheese and hunks of bread, new research has revealed that for children, food was much more disappointing.

By studying the milk teeth of young people living during the 11th to 16th centuries, researchers found they lived on a diet of pap - flour, milk and egg yolk - and bread with broth.

The researchers were able to analyze tiny changes in the amount of wear on the molars from 44 children who died aged between one and eight-years-old.
