HIV: Third case in the world of probable cure after a bone marrow transplant

After a stem cell transplant from a donor with the CCR5-delta 32 mutation, a man was able to stop his antiretroviral treatment without viral resurgence. Four years later, no HIV virus could be detected in his body, indicating probable cure. This case joins two previous reported cases and offers further proof that HIV can be cured.

Black people less likely to receive dementia-related medications

A preliminary study by the American Academy of Neurology found that Black people with dementia are receiving dementia-related medications less often than white people. The study revealed significant disparities in access to treatments, with Black patients receiving fewer prescription types compared to their white counterparts.

Who are the first ancestors of present-day fish?

A new study by Institut Pasteur reveals that the 'bony-tongues' and 'eels' are genetically linked, shedding light on the evolutionary history of teleost fishes. The researchers sequenced genomes of several species and reconstructed relationships between different fish groups.

Lower frequency of vegetable and fruit intake linked to higher risk of death regardless of chronic kidney disease (CKD) status

A new study found that a lower frequency of vegetable and fruit intake was associated with a higher risk of death in patients with and without chronic kidney disease (CKD), regardless of their CKD stage. Higher fruit and vegetable intake is generally linked to lower mortality risk in the general population.

How the brain’s recycling system breaks down in Parkinson’s Disease

Researchers identified a gene linked to Parkinson's Disease also contributes to cell debris buildup in the brain. Autophagy disruption leads to toxic waste accumulation and neuron death, hallmarks of the disease. The discovery could pave the way for new, more effective treatments by targeting autophagy.

Let's get wasted and apply some deep thinking to rubbish

Researchers are developing a deep learning model to predict where waste is accumulating in cities and how often public bins should be cleared. This can help councils optimise their waste management services, schedule bin clearances and relocate rarely used bins.
