Researchers and community scientists monitored urban milkweed plants for butterfly eggs to learn what makes these city gardens more hospitable to monarchs. They found that even tiny city gardens attracted monarchs and became a home to caterpillars.

In a hopeful sign for demand for more safe, effective antibiotics for humans, researchers have leveraged artificial intelligence to develop a new drug that already is showing promise in animal trials.

A new study has revealed how even the deepest seafloors are affected by the daily back-and-forth of the tides, and the change of the seasons, and that currents at the bottom of the ocean are far more complicated than previously thought. These findings are helping us understand the deep-sea pathways of nutrients that support important deep-sea ecosystems, assess where microplastics and other pollutants accumulate in the ocean, and reconstruct past climate change.

Researchers have succeeded in identifying and synthesizing a group of molecules that can act against the cause of tuberculosis in a new way. They describe that the so-called callyaerins act against the infectious disease by employing a fundamentally different mechanism compared to antibiotic agents used to date.

Scientists have revealed that injury dressings found in first-aid kits can reliably be used to identify shark species involved in bite incidents by deploying medical gauze to gather DNA samples from aquatic equipment, such as surfboards.

A research group has developed a new method that further improves the existing CRISPR/Cas technologies: it allows a more precise and seamless introduction of tags into proteins at the gene level. This technology could significantly improve research on proteins in living organisms and opens up new possibilities for medical research.

North Sea oil and gas extraction can cause pollution to spike by more than 10,000 percent within half a kilometer around off-shore sites, a study has found. The research has uncovered the true impact on Britain's seabed life -- with the number of species plummeting nearly 30 percent near platforms.

Two of the closest known relatives to SARS-CoV-2 -- a pair of bat coronaviruses discovered by researchers in Laos -- may transmit poorly in people despite being genetically similar to the COVID-19-causing virus, a new study reveals. The findings provide clues as to why some viruses have greater 'pandemic potential' than others and how researchers might go about identifying those that do before they become widespread.

Nanozymes are tiny, engineered substances that mimic the catalytic properties of natural enzymes, and they serve a variety of purposes in biomedicine, chemical engineering, and environmental applications. They are typically made from inorganic materials, including metal-based elements, which makes them unsuitable for many purposes due to their toxicity and high production costs. Organic-based nanozymes partially overcome some of these problems and have the potential for a broader range of applications, including food and agriculture, but they are still in the early stages of development. A new paper provides an overview of the current state of organic nanozymes and their future potential.

Geneticists uncover new insights into how sex chromosome systems work in the platypus and the chicken -- which will lead to better understandings of our own sex chromosome evolution and gene regulation.

Researchers have modified certain bacteria with UV light so that they produce more cellulose. The basis for this is a new approach with which the researchers generate thousands of bacterial variants and select those that have developed into the most productive.

July 22, 2024, was the hottest day on record, according to a NASA analysis of global daily temperature data. July 21 and 23 of this year also exceeded the previous daily record, set in July 2023. These record-breaking temperatures are part of a long-term warming trend driven by human activities, primarily the emission of greenhouse gases.

Cotton is woven into the very fabric of our lives, from soft T-shirts to comfortable jeans and cozy bedsheets. It's the world's leading renewable textile fiber and the backbone of a global industry worth billions. As climate change intensifies, cotton farmers face increasing challenges from drought and heat. However, new research offers hope for developing more resilient varieties that can maintain high yields even under water-stressed conditions.

A research team has published a groundbreaking study on malignant catarrhal fever (MCF). This disease is caused by the alcelaphine gammaherpesvirus 1 (AlHV-1), which infects its natural host, the wildebeest. This study sheds light on the mechanisms by which this virus, which is asymptomatic and latent in the wildebeest, causes an oligoclonal expansion of CD8+ T lymphocytes in cattle, leading to the development of MCF.

A study opens new perspectives to better understand how the molecular mechanisms involved in regenerative medicine work. The study focuses on tumor necrosis factor- (TNF- ) and its receptors TNFR, molecules of key interest in biomedicine due to their involvement in multiple diseases such as obesity related to type 2 diabetes mellitus, inflammatory bowel disease and several types of cancer.

Using data from 6,645 camera traps across the United States, researchers mapped populations of 25 mammal species. They determined that climate, not human activity, was the primary factor in mammals deciding where to live.
