Epilepsy surgery may improve overall brain health

Epilepsy surgery may be associated with improvements to overall brain health, a study led by University of Liverpool researchers has found. The study, published in Neurology®, the medical journal of the American Academy of Neurology, used advanced magnetic resonance imaging (MRI) techniques to inform its findings. Corresponding author Dr Christophe de Bezenac said: “Many clinicians remain hesitant […]

New insights into how the ‘first brain’ works in the gut

New research explains how the nervous system in the gut, known as the enteric nervous system (ENS) causes propulsion along the gut, highlighting how similar it behaves to other neural networks in the brain and spinal cord. The study, led by Professor Nick Spencer at Flinders University, maintains that the ENS in the gut is […]

Beige fat ‘indispensable’ in protecting the brain from dementia

Beige is considered a calming paint color, and scientists have new evidence that beige fat has a similar impact on the brain, bringing down the inflammation associated with the more common white fat and providing protection from dementia. They have found that beige fat cells, which are typically intermingled with white fat cells in the […]

Neural network scours vast chemical space to design drug-delivering peptides

Large biomolecule drugs’ great promise is held back because it’s hard to get them into cells – but now US researchers have used machine learning to tackle this problem. They developed Peptimizer, a machine learning model that designs cell-penetrating peptides (CPPs) that improve oligonucleotide drug delivery into cells 50-fold. The teams of Rafael Gómez-Bombarelli and […]

Developing countries sidelined in Covid-19 vaccine scramble

The Covax initiative is falling well short of its objective to deliver 2 billion doses of Covid-19 vaccines to lower-income countries by the end of 2021. Wealthy countries, while pledging funds to Covax, have sequestered almost all scheduled vaccine production for the year. Covax is coordinated by Gavi, the Vaccine Alliance; the Coalition for Epidemic […]

Q&A: We need to think differently about how we cool things down

The ability to keep food, medicines, vaccines and our buildings cool underpins much of our modern way of life, but it is also a major source of greenhouse gas emissions. If the world is to meet its development goals and climate change targets over the coming decades, we need to rethink how we keep things […]
