by Vittoria D’Alessio In the battle against antibiotic resistance, some scientists are trying a new approach: re-sensitising bacteria to drugs they no longer respond to so that existing antibiotics can hit their target once more. ‘This is a sustainable and straightforward approach to the problem of antibiotic resistance,’ said Fredrik Almqvist, professor of organic chemistry … Read more

Few aeroplanes land automatically but new systems could make this the norm

Almost half of fatal plane accidents happen between final approach and landing. Image credit - Pixabay/ windhaven1077, licensed under Pixabay license

by Jonathan O’Callaghan When it comes to planes cruising through the air, many of us are used to the idea of them flying on autopilot with little or no input from a human pilot as they travel from one destination to another. Landing a plane under autopilot, known as autoland, is a different matter. While … Read more

New findings about how a human egg matures may help prevent infertility and birth defects

DNA or chromosome errors are found in 20% of women in their early 20s, say researchers.

by Vittoria d’Alessio Decoding how the human egg matures and how this process can go wrong could lead to ways of preventing genetic errors leading to infertility, birth defects or pregnancy loss. Physiological changes known to trigger miscarriages and to increase the likelihood of carrying a child with a genetic condition start in a woman’s … Read more

by Rex Merrifield New weapons are needed to fight drug-resistant bacteria, one of the biggest threats to global health. By working on new antibiotics or finding ways to revive existing ones in our medical arsenal, scientists aim to avoid a return to a world where even everyday infections may mean death. Antibiotics have saved hundreds of … Read more

Scientists speed up the evolution of yeast to create tastier and healthier alcohol

Scientists are speeding up the natural selection process of yeasts to help develop beer and wine that is low in alcohol content. Image credit - U3144362, licensed under CC BY-SA 4.0

Researchers across Europe have started to speed up the evolutionary process of yeast to develop new or better flavours for wine and beer. The objective is for beer and wine producers to better accommodate changing consumer tastes and trends, such as anti-GMO sentiments and demand for low-alcohol products. ‘All kinds of fermentation beverages start out … Read more

Non-antibiotic cures for cows could speed up treatments for people

Mastitis, a bacterial infection that leads to inflammation of a cow's mammary glands and udders, has long been a scourge of the dairy industry. Image credit - Tomasz Jagielski, licensed under CC BY-SA 3.0

by Gareth Willmer As the global antibiotic resistance crisis grows, chemical-based aerosol sprays and electrical signals to wake up the immune system are being developed to treat cow infections. These non-antibiotic therapies for livestock could also help to limit the spread of antibiotic resistance through the human food chain. The animal sector, which uses drugs … Read more
