New "clickable" pseudoviruses could revolutionize virus research

Pseudoviruses resemble impostors: although harmless, they are designed in such a way that they can hardly be distinguished from their dangerous relatives. This makes them an invaluable tool in virus research.

Study sheds light on origins of breast cancer in people with BRCA2 mutations

A pioneering study led by Professor Ashok Venkitaraman from the Cancer Science Institute of Singapore (CSI Singapore) at the National University of Singapore and Dr Mona Shehata from the University of Cambridge (UK) has uncovered vital insights into the distinct effects of BRCA2 mutations on breast tissue cells, shedding light on early breast cancer development in people with BRCA2 mutations.

Existing drug could be repurposed to treat type 1 diabetes, study suggests

Type 1 diabetes is an autoimmune disease that causes the body's immune system to attack and destroy insulin-producing beta cells in the pancreas. Traditional management of type 1 diabetes has primarily involved replacing the missing insulin with injections which, though effective, can be expensive and burdensome.

Cancer neuroscience: A new frontier in cancer treatment

Cancer cells hijack normal biological processes, allowing them to multiply. For example, tumors spur construction of new blood vessels, building themselves "highways" to supply nutrients.

Highly sensitive blood test shows promise for early detection of common deadly cancers

Most cancers become deadly by keeping a low profile, causing no symptoms until they're too advanced to treat. Ovarian and gastroesophageal cancers are among the most notorious for this sly disease progression, often leading to late-stage diagnoses.
