Accelerating drug discovery with fragment screening‎

Modern medicine has played a significant role in improving the length and quality of our lives. While many treatments may seem like miracles, they are the result of a lengthy, rigorous research process. Drug discovery is a particularly time-consuming and costly activity that is fraught with complex challenges and labor-intensive bouts of trial and error.

New study presents the eLTER Framework of Standard Observations for long-term, integrated environmental monitoring‎

A new study published in Earth's Future introduces the eLTER Framework of Standard Observations (eLTER SO)—a structured, harmonized system designed to support consistent long-term environmental observation across Europe. The paper, "Achieving harmonized and integrated long-term environmental observation of essential ecosystem variables - The eLTER Framework of Standard Observations," explains how the eLTER Research Infrastructure (eLTER RI) is improving the comparability and coordination of environmental data across diverse ecosystems and research fields.

Peptide synthesis could stop global potato pathogen once linked to Ireland's Great Famine‎

Scientists in Sweden have taken an important step toward fighting potato late blight, a plant disease that once triggered a historic famine in Ireland and now threatens to spread globally due to climate change. A new study reports the synthesis of a peptide that specifically attacks Phytophthora infestans (P. infestans) to protect potato and tomato crops—without harm to other plants. The work was carried out by researchers at Stockholm's KTH Royal Institute of Technology, in collaboration with research partners in Italy, India and Australia.

What intentional communities can teach us about resilience amid global instability‎

As conflict intensifies in the Middle East, energy markets swing wildly and the cost of living keeps climbing, a pressing question is emerging for anyone who is tied in to the fluctuating energy and food markets: how do we build resilience?

Promiscuity and parental behavior in birds are driven by demographics, not the other way around‎

New research shows that variation in mating behaviors, parental care and differences in ornamentation of the sexes in bird species is driven by demographics rather than vice versa. An international team of researchers from the UK, China, Germany and Hungary looked at 261 species of birds from 69 avian families, running statistical models to investigate the relationship between demographics, adult sex ratio (ASR), breeding behaviors and parental cooperation. Their findings are published in the journal Nature Communications.

Chicken gene-editing advance opens path to drug-producing eggs‎

Chicken eggs are already used to harvest helpful proteins called antibodies to protect humans from viruses such as influenza. Now, a breakthrough at the University of Missouri could one day lead to chickens that produce other useful medical proteins in their eggs.

Stellar flares may expand habitable zones around small stars‎

The search for life beyond Earth has traditionally focused on exoplanets orbiting sun-like stars, which is a G-type star. However, low-mass stars, which are designated as K-type and M-type stars, have rapidly become a target for astrobiology, primarily due to their much longer lifetimes. This also means the habitable zone (HZ), which is the distance from a star where liquid water could exist, is much smaller than our solar system's HZ, and is referred to as the liquid water habitable zone (LW-HZ). In contrast, another type of HZ that involves a star's ultraviolet (UV) radiation potentially enabling life-harboring conditions is known as UV-HZ.

Q&A: Scientists decode the logic behind cells' mysterious protein stockpiles‎

As far as research subjects go, it's not always easy to find common ground with a single-celled bacterium. Yet the more Paul Wiggins studies his model bacteria, Acinetobacter baylyi, the more he sees surprising commonalities between their behavior and our own as humans.

Cosmetics from waste? Microbial discovery unlocks greener route to high-value chemical products‎

Researchers at University of Toronto's Department of Chemical Engineering & Applied Chemistry have made a key discovery about how certain bacterial strains produce a set of economically valuable chemicals—opening the door to new, more sustainable production methods. The finding, published in Nature Microbiology, shows how a family of molecules used in everything from cleaning products to cosmetics to nutritional supplements could be made via bacterial fermentation instead of from palm oil, as they are today.
