New microrobots show promise for future medical applications

Cancer drugs have side effects, so for many years, scientists have been exploring ways to transport the active substances to a tumour in the body as precisely as possible. That is the only place that drugs should take effect.

Researchers identify key molecular processes used by coronaviruses to survive

When a coronavirus--including SARS-CoV-2, which causes COVID-19--infects someone, it hijacks the person's cells, co-opting their molecular machinery for its own survival and spread.

Damage to brain cells causes a chain reaction that impacts 'bystander' neurons

Injury or disease that afflicts a relatively small number of brain cells causes a chain reaction that stops activity across a vast network of neural circuits, according to new research from Oregon Health & Science University.

Tumor DNA in DLBCL patient's stem cells or blood can predict risk of relapse after transplant

Many patients with diffuse large B-cell lymphoma (DLBCL) can be cured by a transplant using their own blood-forming stem cells, but as many as half eventually relapse. New research led by Dana-Farber Cancer Institute scientists suggests that patients whose blood or stem cell samples harbor tumor DNA are likely to relapse.

Researchers discover molecular mechanism of plant immune receptors

In a recent study, Alexander von Humboldt Professor Jijie Chai at the University of Cologne and his team together with MPIPZ researchers have succeeded for the first time in reconstructing the sequence of molecular events that activate an inactive plant immune receptor and thus mediate the death of the host cell.

Researchers demonstrate strategy to control chemical reactions using antibodies

Antibodies are remarkable biomarkers: they are the cues that provide us with indications about many diseases and how our immune system counter them. Now a group of scientists from the University of Rome, Tor Vergata (Italy) has found a way to repurpose them so that they can trigger a specific chemical reaction.
