Life underground suited newly discovered dinosaur fine      (via sciencedaily.com)     Original source 

A newly discovered ancestor of Thescelosaurus shows evidence that these animals spent at least part of their time in underground burrows. The new species contributes to a fuller understanding of life during the mid-Cretaceous -- both above and below ground.

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.

It takes a cool microscope and antifreeze to really look at ice      (via sciencedaily.com)     Original source 

Ice in nature is surrounded by liquid most of the time, and therefore it is key to understand how ice and liquid interact. A new study has now directly observe the precise shape of ice at the interface between ice and liquid -- by using antifreeze and a refrigerated microscope.

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.

Fresh wind blows from historical supernova      (via sciencedaily.com)     Original source 

A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary 'guest star,' now labeled supernova (SN) 1181, which was recorded in historical documents in Japan and elsewhere in Asia. However, after the star dimmed, its location and structure remained a mystery until a team pinpointed its location in 2021. Now, through computer modeling and observational analysis, researchers have recreated the structure of the remnant white dwarf, a rare occurrence, explaining its double shock formation. They also discovered that high-speed stellar winds may have started blowing from its surface within just the past 20-30 years. This finding improves our understanding of the diversity of supernova explosions, and highlights the benefits of interdisciplinary research, combining history with modern astronomy to enable new discoveries about our galaxy.

Blue and great tits deploy surprisingly powerful memories to find food      (via sciencedaily.com)     Original source 

Blue and great tits recall what they have eaten in the past, where they found the food and when they found it, a new study shows. In the first experiment of its kind to involve wild animals, blue and great tits demonstrated 'episodic-like' memory to cope with changes in food availability when foraging. The same study may suggest that humans leaving out seeds and nuts for garden birds could be contributing to the evolution of these memory traits.

Two new species of Psilocybe mushrooms discovered in southern Africa      (via sciencedaily.com)     Original source 

In a new paper, researchers and citizen mycologists describe the two new species as Psilocybe ingeli and Psilocybe maluti. The paper also contains information on the traditional use of P. maluti by Basotho traditional healers from the mountain kingdom of Lesotho. According to the researchers, this appears to be the only recorded first-hand report of hallucinogenic mushrooms being used traditionally in Africa.

A new breakthrough in understanding regeneration in a marine worm      (via sciencedaily.com)     Original source 

The sea worm Platynereis dumerilii is only a few centimeters long but has a remarkable ability: in just a few days, it can regenerate entire parts of its body after an injury or amputation. By focusing more specifically on the mechanisms at play in the regeneration of this worm's tail, a research team has observed that gut cells play a role in the regeneration of the intestine as well as other tissues such as muscle and epidermis.

Research shows how RNA 'junk' controls our genes      (via sciencedaily.com)     Original source 

Researchers have made a significant advance in understanding how genes are controlled in living organisms. The new study focuses on critical snippets of RNA in the tiny, transparent roundworm Caenorhabditis elegans (C. elegans). The study provides a detailed map of the 3'UTR regions of RNA in C. elegans. 3'UTRs (untranslated regions) are segments of RNA involved in gene regulation.

An ant that selectively amputates the infected limbs of wounded sisters      (via sciencedaily.com)     Original source 

Saving lives through surgery is no longer exclusive to humans. Scientists now detail how Florida carpenter ants, a common, brown species native to its namesake, selectively treat the wounded limbs of fellow nestmates -- either by wound cleaning or amputation. When experimentally testing the effectiveness of these 'treatments,' not only did they aid in recovery, but the research team found the ants' choice of care catered to the type of injury presented to them.

Doctors could soon use facial temperature for early diagnosis of metabolic diseases      (via sciencedaily.com)     Original source 

A colder nose and warmer cheeks may be a telltale sign of rising blood pressure. Researchers discovered that temperatures in different face regions are associated with various chronic illnesses, such as diabetes and high blood pressure. These temperature differences are not easily perceptible by one's own touch but can instead be identified using specific AI-derived spatial temperature patterns that require a thermal camera and a data-trained model. With further research, doctors could one day use this simple and non-invasive approach for early detection of diseases.

Organic material from Mars reveals the likely origin of life's building blocks      (via sciencedaily.com)     Original source 

Two samples from Mars together deliver clear evidence of the origin of Martian organic material. The study presents solid evidence for a prediction made over a decade ago that could be key to understanding how organic molecules, the foundation of life, were first formed here on Earth.
