Possible 'Trojan Horse' found for treating stubborn bacterial infections      (via sciencedaily.com)     Original source 

Bacteria can be tricked into sending death signals to stop the growth of their slimy, protective homes that lead to deadly infections, a new study demonstrates. The discovery could someday be harnessed as an alternative to antibiotics for treating difficult infections. The researchers used the messengers, which they named death extracellular vesicles (D-EVs), to reduce growth of the bacterial communities by up to 99.99% in laboratory experiments.

Microalgae with unusual cell biology      (via sciencedaily.com)     Original source 

A globally distributed single-celled organism that occurs in harmful algal blooms has been found to exhibit an unusual organisation of photosynthesis. Researchers have taken a closer look at the unusual cell biology of the species Prorocentrum cordatum from the group of dinoflagellates. The results of their study could help to better understand the role of the species in the environment and the increased occurrence of algal blooms at higher water temperatures.

JWST captures the end of planet formation      (via sciencedaily.com)     Original source 

The James Webb Space Telescope is helping scientists uncover how planets form by advancing understanding of their birthplaces and the circumstellar disks surrounding young stars. Scientists have imaged winds from an old planet-forming disk (still very young relative to the Sun) which is actively dispersing its gas content. Knowing when the gas disperses is important as it constrains the time left for nascent planets to consume the gas from their surroundings.

Modeling the origins of life: New evidence for an 'RNA World'      (via sciencedaily.com)     Original source 

Scientists provide fresh insights on the origins of life, presenting compelling evidence supporting the 'RNA World' hypothesis. The study unveils an RNA enzyme that can make accurate copies of other functional RNA strands, while also allowing new variants of the molecule to emerge over time. These remarkable capabilities suggest the earliest forms of evolution may have occurred on a molecular scale in RNA, and also bring scientists one step closer to re-creating autonomous RNA-based life in the laboratory.

An evolutionary mystery 125 million years in the making      (via sciencedaily.com)     Original source 

Plant biologists have uncovered an evolutionary mystery over 100 million years in the making. It turns out that sometime during the last 125 million years, tomatoes and Arabidopsis thaliana plants experienced an extreme genetic makeover. Just what happened remains unclear. But the mystery surrounds CLV3, a gene key to healthy plant growth and development.

Advances in forensic science improve accuracy of 'time of death' estimates      (via sciencedaily.com)     Original source 

Accurate 'time of death' estimates are a mainstay of murder mysteries and forensic programs, but such calculations in the real world are often complex and imprecise. In a first-of-its-kind study, researchers have discovered a group of common microbes that work together specifically to decompose flesh. These microorganisms serve as a biological clock and allow scientists to investigate the post-mortem breakdown of tissue with unprecedented precision.

New antibodies target 'dark side' of influenza virus protein      (via sciencedaily.com)     Original source 

Researchers have identified antibodies targeting a hard-to-spot region of the influenza virus, shedding light on the relatively unexplored 'dark side' of the neuraminidase (NA) protein head. The antibodies target a region of the NA protein that is common among many influenza viruses, including H3N2 subtype viruses, and could be a new target for countermeasures.
