Wild plants and crops don't make great neighbors, research finds      (via sciencedaily.com)     Original source 

Native plants and non-native crops do not fare well in proximity to one another, attracting pests that spread diseases in both directions, according to two new studies.

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.

Wolves' return has had only small impact on deer populations in NE Washington      (via sciencedaily.com)     Original source 

Wolves returned to Washington state in 2008. A new study shows that, despite their rising numbers, wolves are not having much of an impact on white-tailed deer, one of their primary prey. Scientists report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available, which is largely determined by human activity. Cougars were second in their impact. Wolves were a distant third.

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.

Moving from the visible to the infrared: Developing high quality nanocrystals      (via sciencedaily.com)     Original source 

Awarded the 2023 Nobel Prize in Chemistry, quantum dots have a wide variety of applications ranging from displays and LED lights to chemical reaction catalysis and bioimaging. These semiconductor nanocrystals are so small -- on the order of nanometers -- that their properties, such as color, are size dependent, and they start to exhibit quantum properties. This technology has been really well developed, but only in the visible spectrum, leaving untapped opportunities for technologies in both the ultraviolet and infrared regions of the electromagnetic spectrum.

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.

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.

A 2D device for quantum cooling      (via sciencedaily.com)     Original source 

Engineers have created a device that can efficiently convert heat into electrical voltage at temperatures lower than that of outer space. The innovation could help overcome a significant obstacle to the advancement of quantum computing technologies, which require extremely low temperatures to function optimally.

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.

Giant clams may hold the answers to making solar energy more efficient      (via sciencedaily.com)     Original source 

Solar panel and biorefinery designers could learn a thing or two from iridescent giant clams living near tropical coral reefs, according to a new study. This is because giant clams have precise geometries -- dynamic, vertical columns of photosynthetic receptors covered by a thin, light-scattering layer -- that may just make them the most efficient solar energy systems on Earth.

Spotted apex predator being pressured by spotted pack hunters -- and it's our fault      (via sciencedaily.com)     Original source 

Leopards, who are already in decline, can't keep up with hyenas when people are around. As we humans move into the their territories more and more, we are helping to disturb and unbalance ecosystems. This has been shown in a new study where researchers used camera traps to observe both large carnivore species.
