Biosignatures may reveal a wealth of new data locked inside old fossils
Step aside, skeletons — a new world of biochemical “signatures” found in all kinds of ancient fossils is revealing itself to paleontologists, providing a new avenue for insights into major evolutionary questions.

Parallel evolution in three-spined sticklebacks what happens in the Eastern Pacific, stays in the Eastern Pacific
The three-spined stickleback ( Gasterosteus aculeatus ), a thumb-sized fish distributed across the Northern hemisphere, is a textbook model species in evolutionary biology. With the retreat of ice sheets since the last glacial maximum, ancestral marine populations have repeatedly colonised newly formed freshwater habitats. Across their distribution range, sticklebacks in these novel freshwater environments exhibit remarkable similarities in their morphology, physiology and behaviour, a phenomenon known as “parallel evolution”.

A new test can see -- almost literally -- infectious bacteria
Urinary tract infections, or UTIs, are one of the most common bacterial infections in the world. With some serious exceptions, they can usually be treated with off-the-shelf prescription antibiotics, and since the symptoms are easily recognized, physicians commonly prescribe antibiotics without waiting for a lab test. The infections are usually resolved within a week.

Study Reveals Continuous Pathway to Building Blocks of Life
Researchers have long sought to understand the origins of life on Earth. A new study conducted by scientists at the Institute for Advanced Study, the Earth-Life Science Institute (ELSI), and the University of New South Wales, among other participating institutions, marks an important step forward in the effort to understand the chemical origins of life.

Record number of countries contribute data revealing disturbing rates of antimicrobial resistance
Geneva—A record number of countries are now monitoring and reporting on antibiotic resistance - marking a major step forward in the global fight against drug resistance. But the data they provide reveals that a worrying number of bacterial infections are increasingly resistant to the medicines at hand to treat them.

Patients with Metastatic Pancreatic Cancer and DNA Repair Defects May Have Improved Survival after Platinum-based Chemotherapy
PHILADELPHIA – Patients with metastatic pancreatic cancer who had germline or somatic mutations in DNA repair genes had better clinical outcomes after platinum-based chemotherapy, as compared with patients without these mutations, according to results from a study published in Clinical Cancer Research , a journal of the American Association for Cancer Research.

Scientists discover mutation that enhances plant defense
Sometimes scientists begin research and find exactly what they expected. Other times they discover something unexpected. Such was the case for a group of scientists studying plant stress responses who stumbled upon a new mutation.

Gene flow between species influences evolution in Darwins finches
Princeton ecologists Peter and Rosemary Grant led a team of researchers to discover how genetics and hybridization affected the beak shape of finches on the Galápagos Islands, such as this medium ground finch with its characteristic blunt beak. This particular specimen was banded by the husband-and-wife team during their field studies on Daphne Major.

Research Brief: Engineering natural selection in microbes has implications for biofuel production, addressing antibiotic resistance
Scientists who study adaptation — or edit the genes of organisms — know the limitations inherent in conventional approaches to mutation that offer little opportunity to target individual genes without altering others as well.

New insight into bacterial surface architecture revealed
University of Sheffield scientists have produced the first high resolution images of the cell wall of the deadly bacterium Staphylococcus aureus, better known as its antibiotic resistant form, MRSA Research will help scientists combat antibiotic resistance Findings overturn previous theories about the structure of these outer bacterial layers.

Bacteria that are persistently resistant to one antibiotic are primed to become multidrug-resistant bugs
Antibiotics save lives — but using them also helps antibiotic-resistant strains evolve and spread. Each year, antibiotic-resistant bacteria infect some 2.8 million people in the United States, killing more than 35,000, according to the Centers for Disease Control and Prevention. Infections by multidrug-resistant — or MDR — bacteria, which are resistant to two or more antibiotics, are particularly difficult to treat.

Mercks Dr. Julie Gerberding on the threat of antimicrobial resistance and COVID-19
As America?s biopharmaceutical companies work around the clock to combat COVID-19, a disease caused by a novel strain of coronavirus, now is an important time to consider how we can prepare for the next public health emergency: Antimicrobial resistance (AMR).

Predicting the evolution of genetic mutations
The algorithm called “minimum epistasis interpolation” results in a visualization of how a protein could evolve to either become highly effective or not effective at all. David McCandlish and his colleagues compared the functionality of thousands of versions of the protein, finding patterns in how mutations cause the protein to evolve from one functional form to another.
