The other side of the story: How evolution impacts the environment      (via sciencedaily.com)     Original source 

Researchers show that an evolutionary change in the length of lizards' legs can have a significant impact on vegetation growth and spider populations on small islands in the Bahamas. This is one of the first times, the researchers say, that such dramatic evolution-to-environment effects have been documented in a natural setting.

Finally solved! The great mystery of quantized vortex motion      (via sciencedaily.com)     Original source 

Scientists investigated numerically the interaction between a quantized vortex and a normal-fluid. Based on the experimental results, researchers decided the most consistent of several theoretical models. They found that a model that accounts for changes in the normal-fluid and incorporates more theoretically accurate mutual friction is the most compatible with the experimental results.

Symbiotic and pathogenic fungi may use similar molecular tools to manipulate plants      (via sciencedaily.com)     Original source 

Symbiotic and pathogenic fungi that interact with plants are distantly related and don't share many genetic similarities. Comparing plant pathogenic fungi and plant symbiotic fungi, scientists at the Sainsbury Laboratory Cambridge University (SLCU) have discovered that these remote relatives are using a similar group of proteins to manipulate and live within plants.

New method improves efficiency of 'vision transformer' AI systems      (via sciencedaily.com)     Original source 

Vision transformers (ViTs) are powerful artificial intelligence (AI) technologies that can identify or categorize objects in images -- however, there are significant challenges related to both computing power requirements and decision-making transparency. Researchers have now developed a new methodology that addresses both challenges, while also improving the ViT's ability to identify, classify and segment objects in images.

Phenomenal phytoplankton: Scientists uncover cellular process behind oxygen production      (via sciencedaily.com)     Original source 

According to new research, the amount of oxygen in one of 10 breaths was made possible thanks to a newly identified cellular mechanism that promotes photosynthesis in marine phytoplankton. The new study identifies how a proton pumping enzyme (known as VHA) aids in global oxygen production and carbon fixation from phytoplankton.

Study leads to milestone advances in understanding lethal bronzing of palm trees      (via sciencedaily.com)     Original source 

Scientists have identified a key chemical associated with lethal bronzing (LB) infected palm trees. LB is a bacterial disease that kills more than 20 species of palm trees in the Southern United States and Caribbean and has been devastating the Florida green industries for nearly two decades.

Plants can distinguish when touch starts and stops, study suggests      (via sciencedaily.com)     Original source 

Even without nerves, plants can sense when something touches them and when it lets go, a study has found. In a set of experiments, individual plant cells responded to the touch of a very fine glass rod by sending slow waves of calcium signals to other plant cells, and when that pressure was released, they sent much more rapid waves. While scientists have known that plants can respond to touch, this study shows that plant cells send different signals when touch is initiated and ended.

Light conveyed by the signal transmitting molecule sucrose controls growth of plant roots      (via sciencedaily.com)     Original source 

Researchers shows how information about the quantity of absorbed light passes from the leaves to the roots. Photosynthetic sucrose not only supplies roots with carbohydrates but also acts as a signal transmitter for light-dependent root architecture.

Weevils, long-nosed beetles, are unsung heroes of pollination      (via sciencedaily.com)     Original source 

Some of nature's most diverse pollinators often go unnoticed, even by scientists: long-snouted beetles called weevils. A new study provides a deep dive into the more than 600 species of weevils, including ones whose entire life cycles are interwoven with a specific plant that they help pollinate.

New method predicts extreme events more accurately      (via sciencedaily.com)     Original source 

A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they are too small. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.

Identifying the bee's knees of bumble bee diets      (via sciencedaily.com)     Original source 

A new study has identified the bee's knees of bumble bee dietary options in Ohio and the Upper Midwest. By viewing almost 23,000 bumble bee-flower interactions over two years, researchers found that these bees don't always settle for the most abundant flowers in their foraging area -- suggesting they have more discerning dietary preferences than one might expect.
