Drug discovery bottleneck? Cell-free platform screens peptides faster, even in harsh conditions‎

Many biological functions are regulated by the switching on and off of mechanisms triggered by the matching of a keyhole (receptor) formed by a protein's three-dimensional structure and a molecule (ligand) that fits perfectly into it. If this keyhole deforms (protein mutation) or if a false key is created, biological functions become disrupted, leading to disease. Drug discovery research involves a process called screening to find compounds that fit into these receptor lock-and-key sites.

High-performance cell atlas workflow driven by manifold fitting‎

Researchers from the National University of Singapore (NUS) have developed CellScope, a high-performance single-cell analysis framework that uses manifold fitting to analyze single-cell RNA sequencing (scRNA-seq) data. This framework helps build detailed "cell atlases" that map different cell types and show how they further group into finer subtypes.

New computation method for climate extremes: Researchers reveal 10-fold increase in heat over Europe‎

How much will heat, flooding, drought and storms increase as a result of human-induced climate change? In a groundbreaking study, climate researcher Gottfried Kirchengast and his team at the University of Graz have developed a new method for computing the hazards from extreme events: it can compute all relevant hazard metrics for events such as heat waves, floods and droughts in any region worldwide with unprecedented information content.

Enhanced rock weathering is not yet a reliable climate protection measure, say researchers‎

Most countries will not achieve climate neutrality through greenhouse gas emission reductions alone; carbon sinks are also needed to offset unavoidable emissions. Researchers are discussing technical solutions, such as applying silicate-rock powder to arable land. This process, known as enhanced rock weathering (ERW), can bind carbon dioxide from the atmosphere.

Why crowning the protein that makes jellyfish glow green as a model can help scientists streamline biology‎

Fruit flies, mice, zebrafish, yeast and the tiny worm C. elegans are model organisms that have carried modern biology on their backs.

'Don't leave late' is the best advice for fires or floods. These terrifying videos show why‎

Where are you at most risk when a flood or bushfire strikes? You might think it's at home. But in reality, the most dangerous time is when you leave and jump in your car. Many flood and bushfire deaths are linked to vehicles, often driven by people evacuating late.

Nanoparticle system shows promise for delivering mRNA to prevent type 1 diabetes‎

Research on preventing type 1 diabetes often focuses on limiting the autoimmune response that destroys the body's ability to produce its own insulin. A new technology developed by scientists at the University of Chicago takes a different approach, centered on preserving insulin-producing beta cells by giving them the ability to protect themselves.
