Food aroma study may help explain why meals taste bad in space      (via sciencedaily.com)     Original source 

A new study on common food aromas may help explain why astronauts report that meals taste bland in space and struggle to eat their normal nutritional intake. This research has broader implications for improving the diets of isolated people, including nursing home residents, by personalizing aromas to enhance the flavor of their food.

First ever 3D reconstruction of 52,000-year-old woolly mammoth chromosomes thanks to serendipitously freeze-dried skin      (via sciencedaily.com)     Original source 

An international research team has assembled the genome and 3D chromosomal structures of a 52,000-year-old woolly mammoth -- the first time such a feat has been achieved for any ancient DNA sample. The fossilized chromosomes, which are around a million times longer than most ancient DNA fragments, provide insight into how the mammoth's genome was organized within its living cells and which genes were active within the skin tissue from which the DNA was extracted. This unprecedented level of structural detail was retained because the mammoth underwent freeze-drying shortly after it died, which meant that its DNA was preserved in a glass-like state.

A new species of extinct crocodile relative rewrites life on the Triassic coastline      (via sciencedaily.com)     Original source 

The surprising discovery of a new species of extinct crocodile relative from the Triassic Favret Formation of Nevada, USA, rewrites the story of life along the coasts during the first act of the Age of Dinosaurs. The new species Benggwigwishingasuchus eremicarminis reveals that while giant ichthyosaurs ruled the oceans, the ancient crocodile kin known as pseudosuchian archosaurs ruled the shores across the Middle Triassic globe between 247.2 and 237 million years ago.

Lion with nine lives breaks record with longest swim in predator-infested waters      (via sciencedaily.com)     Original source 

A record-breaking swim by two lion brothers across a predator-infested African river has been documented in a new study. The researchers say the 1km swim is another example of iconic wildlife species having to make tough decisions to find homes and mates in a human-dominated world.

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.

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.

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.

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.
