Results suggest radiotracer maraciclatide can ‘light up’ condition on scan and reduce need for investigative surgery

A non-invasive scan for endometriosis has shown promising results in a trial, boosting hopes for far quicker diagnosis.

The trial, which included 19 women with the condition, suggests that an experimental radiotracer, called maraciclatide, can “light up” endometriosis on a scan. The current need for a surgical investigation is seen as a major obstacle to timely diagnosis, with women in England typically waiting nearly a decade.

People with meniscus tears who underwent surgery had poorer knee function and worse osteoarthritis after 10 years than those who did not

A common knee surgery for cartilage damage does not benefit patients and may lead to worse outcomes, a 10-year trial suggests.

The study tracked outcomes for patients treated for a meniscus tear, who were given a partial meniscectomy, one of the most common orthopaedic surgeries. Their trajectories were compared with patients who had randomly been assigned to receive “sham surgery”, in which no procedure was carried out.

Patrick Vallance says government working with Chinese officials to remove postings from Alibaba after Biobank data breach last week

There have been further listings of confidential health records of UK volunteers on the Chinese website Alibaba since the breach reported last week, and the government is braced for further leaks, the science minister has said.

Addressing a House of Lords debate on the attempted sale of data belonging to 500,000 UK Biobank volunteers, Patrick Vallance said the government had worked with Chinese officials to remove additional postings on the online marketplace.

Scientists think they are looking at chemical building blocks of life preserved for 3.5bn years

Nasa’s Curiosity rover has detected organic molecules on Mars, including chemicals widely considered building blocks for the origin of life of Earth.

Five of the seven molecules identified in a dried lakebed near the equator had never previously been observed on the red planet. The analysis, performed by the robotic rover, cannot establish whether the organic compounds are linked to potential ancient life on Mars or were delivered by meteorites or formed through geological processes. However, they imply that if microbial life once thrived on Mars, chemical fingerprints should remain there today.
