Sensor based on quantum physics could detect SARS-CoV-2 virus

A novel approach to testing for the presence of the virus that causes COVID-19 may lead to tests that are faster, less expensive, and potentially less prone to erroneous results than existing detection methods. Though the ...

PCR tests activated by light

A new approach by LMU chemists could help to significantly improve diagnostic tests based on PCR. The enzymes used are triggered by light pulses.

Wrangling an octopus-like viral replication machine

Endemic in Western African countries, Lassa virus is transmitted to humans through food or household items that are contaminated with the urine or feces of Mastomys rats. Even though many people who become infected with Lassa ...

Cells' replication of DNA is more 'error-prone' in microgravity

On 22 May 2019, scientists from Queen's University boarded a modified Falcon 20 aircraft at Ottawa airport. Scheduled was a 'vomit comet' flight, where the plane repeatedly climbs to 8km in a steep parabola, alternating with ...

DNA replication under the microscope

Cryogenic electron microscopy (cryo-EM) has enabled researchers to study how the DNA replication machinery assembles at sites where DNA is damaged.
