Where does the vaccine for Covid-19 stand?

May 11, 2025 • 10:30 AM

In the worldwide race for a vaccine to stop the coronavirus, the laboratory sprinting fastest is at Oxford University. Most other teams have had to start with small clinical trials of a few hundred participants to demonstrate safety. But scientists at the university's Jenner Institute had a head start on a vaccine, having proved in previous trials that similar inoculations, including one last year against an earlier coronavirus, were harmless to humans. That has enabled them to leap ahead and...

Study finds smoking e-cigarettes could cause cancer

May 11, 2025 • 10:30 AM

A recent study hints that e-cigarette smoke may contribute to lung and bladder cancer, as well as heart disease, in humans.

Using mice models for their study, scientists at the Department of Environmental Medicine, New York University School of Medicine, have proposed that e-cigarette smoking is carcinogenic. The study results also found that e-cigarette smokers are at a higher risk of developing lung and bladder cancers and heart diseases compared to non-smokers.

Smoking tobacco creates a...

Flu virus becomes more virulent in pregnant women

May 11, 2025 • 10:30 AM

When a woman is pregnant, her immune system is dampened to protect the unborn foetus. This is because the baby is recognised as a foreign being by the mother's immune system - the baby is genetically different to that of the mother.

Scientists at the
Heinrich Pette Institute in Hamburg have shown in mice that the mother's suppressed immune system provides a unique opportunity for the influenza virus not only to infect the mother but to evolve into a more powerful strain.

"Pregnant women become...

High-salt diet linked to dementia in mice

May 11, 2025 • 10:30 AM

Scientists have discovered that a diet which is high in salt, can have major effects on the brain and in mice, can lead to dementia. The study, published in Nature Neuroscience, is the first to identify a link between the gut and the brain and that it is responsible for cognitive impairment.  This finding explores the possibility of preventing detrimental effects to the brain caused by an excess in salt intake. Dr. Costantino Iadecola, of the Feil Family Brain and Mind Research Institute at...

Breastfeeding rates increased by financial incentives

May 11, 2025 • 10:30 AM

Breastfeeding rates increase when new mothers are offered financial incentives. Research from the University of Sheffield and the University of Dundee reveals that when mothers are offered vouchers to breastfeed their babies, the low rates of breastfeeding are significantly increased.

The study looked at over 10,000 new mothers in England, aged 16-44, who were offered £40 on five separate occasions if their child received breastmilk at two days, ten days, six weeks, three months and six months...
