Nanopore technology identifies proteins molecule by molecule
Proteins are responsible for most functions in the human body. However, their analysis, which is essential for understanding diseases, developing drugs and discovering new biomarkers, remains highly complex. Using a technology called "nanopore detection," a team at the University

Structural blueprint for RNA therapeutics reveals why some siRNA molecules work better tha
RNA interference is a natural mechanism for living cells to control whether specific genes are being used. Crowned with the 2006 Nobel Prize in Physiology or Medicine, the discovery of RNA interference has since been harnessed by scientists to create a powerful and growing class
Scientists may have finally found how Alzheimer's spreads through the brain
Scientists may have finally found how Alzheimer's spreads through the brain
A common brain protein may be giving Alzheimer’s disease an unexpected way to spread, carrying toxic Tau proteins from damaged neurons into healthy ones. By blocking these harmful protein packages before they reach new cells, researchers believe it may one day be possible to slow
Medici brothers' remains reveal Renaissance-era malaria strains, closing the book on a mur
In 1562, Cardinal Giovanni de Medici, a scion of the dynastic family that dominated politics and banking in Tuscany during the Renaissance, died of malaria. Twenty-five years later, his older brother, Grand Duke Francesco de Medici, succumbed to the same disease.
Ancient gum disease may have helped reshape jaws before human brains expanded
Ancient gum disease may have helped reshape jaws before human brains expanded
Human evolution is generally explained through changes in brain size, locomotion or tool use, but new research from Wits University suggests that gum disease and changes in facial structure may have been important factors in shaping the evolutionary path that ultimately led to mo

Feline fleas carry bacteria linked to human disease in South Texas, study finds
As human cases of flea-borne murine typhus continue to occur in South Texas, researchers are working to better understand the role cats and their fleas may play in the disease's transmission cycle.
Insect-borne diseases in the Amazon linked to land use and rural economies
Diseases spread by insects in the Brazilian Amazon are not randomly distributed but form distinct regional patterns linked to land use, rural economies and environmental change, according to new research led by the Environmental Change Institute (ECI) at the University of Oxford.
Scientists may have finally found how Alzheimer's kills brain cells
Scientists may have finally found how Alzheimer's kills brain cells
Researchers have identified a previously overlooked mechanism of brain cell death that appears to play a major role in Alzheimer's disease and frontotemporal dementia. The finding could lead to new treatments aimed at slowing neuron loss by interrupting the process before cells a
Survival comes at a price: Frog study links salt adaptation to increased risk of disease
Survival comes at a price: Frog study links salt adaptation to increased risk of disease
Over generations, a small North American frog has learned how to survive in a world that's getting increasingly saltier. But new research from the University of Missouri suggests that adaptation comes with an unexpected trade-off.
Fighting the world's deadliest infection with PAC-MAN and AI
Tuberculosis, caused by the bacterium Mycobacterium tuberculosis (Mtb), is the world's deadliest single-agent infection, responsible for 1.23 million deaths in 2024, according to the World Health Organization. The bacterium's unique outer cell membrane is notoriously hard to pene
‘A break from scrolling’: how Gen Z fell in love with birding – podcast
In the last 50 years, Britain has lost an astonishing 73 million wild birds from its landscape, according to the British Trust for Ornithology. Habitat loss, pesticides, disease, cats and the climate crisis mean there are fewer birds than ever before. For children and young peopl
Peru Amazon highway tied to 400% dengue surge within 5 kilometers of road
New roads bring changes to the regions they traverse. They can enable job opportunities, access to medicine and health care, and electricity. But they also disrupt local ecosystems and can have surprising consequences for human health, including increased disease risk.
