Team develops a rapid test to measure immunity to SARS-CoV-2

Mount Sinai researchers have developed a rapid blood assay that measures the magnitude and duration of someone's immunity to SARS-CoV-2, the virus that causes COVID-19. This test will allow large-scale monitoring of the population's ...

Developing a better diagnostic nano-probe

Biomarkers are components that may be present in biological samples and are related to specific diseases. Therefore, doctors can analyze biological samples from a patient to check their health condition or to monitor the ...

Using cold to enhance microscopy

Fluorescence light microscopy has the unique ability to observe cellular processes over a scale that bridges four orders of magnitude. Yet, its application to living cells is fundamentally limited by the very rapid and unceasing ...

No US return to the Moon before 2026: audit

The return of humans to the Moon, already postponed last week by NASA from 2024 to 2025, will actually take place in 2026 "at the earliest", according to a government audit published on Monday.

Trapping light with disorder

Like a pinball game in the hands of a good player, a collection of obstacles randomly positioned can be sufficient to trap light without the need for an optical cavity. By adding amplification, at no cost, a mirrorless laser—often ...

Acoustic tweezers can pick up objects without physical contact

Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound transducers to generate ...
