The plague may have caused the downfall of the Stone Age farmers      (via sciencedaily.com)     Original source 

Ancient DNA from bones and teeth hints at a role of the plague in Stone Age population collapse. Contrary to previous beliefs, the plague may have diminished Europe's populations long before the major plague outbreaks of the Middle Ages, new research shows.

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.

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.

Cracking open a tasty menu for captive marsupials to sink their teeth into      (via sciencedaily.com)     Original source 

From sifting through topsoil for native truffles to cracking open hard shells of seeds and nuts to munch on the tasty kernels, Australia bettongs and potoroos are described as 'ecosystem engineers' in a two-way relationship between their rich diet and environmental health. However, with native ecosystems and potoroid marsupial numbers in decline, ecology and evolution experts are working to understand how difficult it is to bite into the foods these leading foragers seek out.

Ancient large kangaroo moved mainly on four legs, according to new research      (via sciencedaily.com)     Original source 

A type of extinct kangaroo that lived during the Pleistocene around two and a half million to ten thousand years ago, known as the 'giant wallaby', was a poor hopper, a study has found.

New way for beneficial microbes to survive extreme conditions and space exploration      (via sciencedaily.com)     Original source 

Investigators sought to help figure out how to send materials like probiotics into space and to better treat a variety of gastrointestinal (GI) and metabolic diseases. The team's formulations allow microbial therapeutics, including those used to treat gastrointestinal diseases and improve crop production, to maintain their potency and function over time despite extreme temperatures.

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.

Ancient dingo DNA shows modern dingoes share little ancestry with modern dog breeds      (via sciencedaily.com)     Original source 

A study of ancient dingo DNA revealed that the distribution of modern dingoes across Australia, including those on K'gari (formerly Fraser Island), pre-dates European colonization and interventions like the dingo-proof fence.

Restored oyster sanctuaries host more marine life      (via sciencedaily.com)     Original source 

Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.
