Sterile spikelets improve yield in sorghum and related grasses, shows study

Much of the food we eat comes from grasses such as rice, wheat, corn, sorghum, and sugarcane. These crops still resemble the wild species from which they were derived. In all grasses the structures that contain the flowers and seeds are called spikelets.

A digital CRISPR-based method for quick detection and absolute quantification of SARS-CoV-2

In a recent medRxiv* preprint manuscript, researchers from Singapore and the United States report the development of a digital CRISPR method for the sensitive, specific, and rapid detection of viral nucleic acids at a constant temperature, which could be exploited for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Llama antibodies could be a potent nanoweapon against COVID-19

Today in Science, researchers at the University of Pittsburgh School of Medicine describe a new method to extract tiny but extremely powerful SARS-CoV-2 antibody fragments from llamas, which could be fashioned into inhalable therapeutics with the potential to prevent and treat COVID-19.

Nanobodies efficiently neutralize SARS-CoV-2 in cells

Two separate studies have identified nanobodies - which could be produced less expensively than monoclonal antibodies - that bind tightly to the SARS-CoV-2 spike protein and efficiently neutralize SARS-CoV-2 in cells.

Study describes the effects of a DPP3-knockout on the renin-angiotensin system

The role of the enzyme dipeptidyl peptidase 3 in the blood pressure-regulating renin-angiotensin system was investigated in the inter-university cooperation project BioTechMed-Graz. The results could pave the way for new therapies for cardio-renal diseases.

Chikungunya can infect central nervous system and impair cognitive, motor functions

A study conducted by an international team of researchers with FAPESP's support shows that infection by chikungunya virus can produce even more severe manifestations than the typical symptoms of the disease, such as acute fever, headache, rash, and intense joint and muscle pain.
