Discovery of a new defense mechanism in bacteria      (via sciencedaily.com)     Original source 

When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defense mechanism using cell-to-cell communication to 'warn' unaffected bacteria, which can then anticipate, shield themselves and spread the warning signal.

The detection of a massive harmful algal bloom in the Arctic prompts real-time advisories to western Alaskan communities      (via sciencedaily.com)     Original source 

A summer 2022 research cruise that detected a massive and highly toxic harmful algal bloom (HAB) in the Bering Strait has provided a dramatic example of science that utilized new technology to track a neurotoxic HAB and effectively communicate that information in real-time to protect remote communities in coastal Alaska.

Phage-derived enzyme targets E. faecalis biofilms to mitigate acute graft-versus-host disease      (via sciencedaily.com)     Original source 

Acute graft-versus-host disease occurs when donor immune cells attack the recipient's tissues after an allogeneic hematopoietic stem cell transplantation (allo-HCT). Researchers recently identified a bacteriophage-derived enzyme called endolysin capable of targeting biofilms formed by Enterococcus faecalis. Their findings offer hope for tailored interventions in allo-HCT.

Tackling the challenge of coca plant ID: Wild vs cultivated for cocaine      (via sciencedaily.com)     Original source 

A new paper reveals that it's not as straightforward as it might seem. Despite decades of data collection by the United Nations Office on Drugs and Crime (UNODC), which has been valuable to monitor changes in areas occupied by illegal coca plantations in South America, there is no reliable scientific method to distinguish between different types of coca plants.

New one-step method to make multiple edits to a cell's genome      (via sciencedaily.com)     Original source 

A team of scientists have developed a new method that enables them to make precise edits in multiple locations within a cell -- all at once. Using molecules called retrons, they created a tool that can efficiently modify DNA in bacteria, yeast, and human cells.

Whale remains tracked to highlight sustainable disposal benefits      (via sciencedaily.com)     Original source 

A new study highlights the sustainable, cultural and ecosystem benefits of offshore removal or decomposition of whale remains. The study tracked the remains of a humpback whale that was intercepted before washing up on the shoreline, then repositioned 30km offshore and fitted with a satellite tag that tracked its position as it drifted with the wind and currents for 6 days before falling to the seabed.

Groundbreaking study reveals oceanic seabirds chase tropical cyclones      (via sciencedaily.com)     Original source 

A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.

How a plant app helps identify the consequences of climate change      (via sciencedaily.com)     Original source 

A research team has developed an algorithm that analyses observational data from a plant identification app. The novel approach can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.

'Sacrifice' of virus data clears the path to open a disease discovery pipeline      (via sciencedaily.com)     Original source 

Tens of millions of still-unknown or misunderstood viruses can cause diseases -- including new pandemics -- and affect the health of valuable terrestrial and marine environments. Now a new pipeline to investigate the 'virosphere,' or all the genomes of viruses and bacteriophages (viruses that attack bacteria) of the world, has been developed by an international collaboration.

Raw milk is risky, but airborne transmission of H5N1 from cow's milk is inefficient in mammals      (via sciencedaily.com)     Original source 

While H5N1 avian influenza virus taken from infected cow's milk makes mice and ferrets sick when dripped into their noses, airborne transmission of the virus between ferrets -- a common model for human transmission -- appears to be limited. These and other new findings about the strain of H5N1 circulating among North American dairy cattle this year come from a set of laboratory experiments. Together, they suggest that exposure to raw milk infected with the currently circulating virus poses a real risk of infecting humans, but that the virus may not spread very far or quickly to others.

Scientists discover how to improve vaccine responses to potentially deadly bacterium      (via sciencedaily.com)     Original source 

Researchers have taken a leap forward in understanding how we might fight back against the potentially deadly MRSA bacterium. They have shown in an animal model that targeting a key suppressive immune molecule (IL-10) during the delivery of a vaccine improves the ability of the vaccine to protect against infection.

Study reveals environmental impact of artificial sweeteners      (via sciencedaily.com)     Original source 

A recently published study demonstrates how sucralose affects the behavior of cyanobacteria -- an aquatic photosynthetic bacteria -- and diatoms, microscopic algae that account for more than 30% of the primary food production in the marine food chain.
