Connecting the dots to shape growth forces      (via sciencedaily.com)     Original source 

Branching patterns are prevalent in our natural environment and the human body, such as in the lungs and kidneys. For example, specific genes that express growth factor proteins are known to influence the development of the lungs' complex branches. Researchers have unveiled a regulatory system linking signal, force, and shape in mouse lung structure development. The team recognized that the signal protein ERK plays an active role in causing growing lung tissue to curve.

Synaptic protein change during development offers clues on evolution and disease      (via sciencedaily.com)     Original source 

An analysis of how synaptic proteins change during early development reveals differences between mice and marmosets but also what's different in individuals with autism spectrum disorders. The findings offer first insights into the mechanism behind synaptic development and open up routes for research on possible treatments.

A combination of approved drugs enhances the delivery of anti-bacterial medications to treat tuberculosis      (via sciencedaily.com)     Original source 

Researchers have found that approved drugs that were originally shown to normalize blood vessels surrounding tumors (to improve drug delivery to cancer cells) can enhance the delivery of anti-microbial medications to kill tuberculosis bacteria residing in the lungs.

Sweet success: Sugarcane's complex genetic code cracked      (via sciencedaily.com)     Original source 

Scientists created a highly accurate reference genome for one of the most important modern crops and found a rare example of how genes confer disease resistance in plants. Exploring sugarcane's genetic code could help researchers develop more resilient and productive crops, with implications for both sugar production and biofuels.

Scientists extract genetic secrets from 4,000-year-old teeth to illuminate the impact of changing human diets over the centuries      (via sciencedaily.com)     Original source 

Researchers have recovered remarkably preserved microbiomes from two teeth dating back 4,000 years, found in an Irish limestone cave. Genetic analyses of these microbiomes reveal major changes in the oral microenvironment from the Bronze Age to today. The teeth both belonged to the same male individual and also provided a snapshot of his oral health.

New technique for predicting protein dynamics may prove big breakthrough for drug discovery      (via sciencedaily.com)     Original source 

Understanding the structure of proteins is critical for demystifying their functions and developing drugs that target them. To that end, a team of researchers has developed a way of using machine learning to rapidly predict multiple protein configurations to advance understanding of protein dynamics and functions.

Combination of the climate crisis and continued deforestation may result in significant damage to the animal world      (via sciencedaily.com)     Original source 

A new study states that the combination of global warming and extreme heat events, alongside the continued expansion of deforestation in the world, may be devastating for many species of animals, especially those that know how to climb trees. As part of the study, the researchers focused on lizards and showed that following the effects of climate change, they will seek refuge from the hot ground by spending a lot of time on trees. However, due to human-related activities, such as deforestation, urbanization and the expansion of agricultural lands at the expense of natural lands, the availability of trees in the areas where the lizards live will decrease, and this may lead to the collapse of many populations.

Researchers find energy development and tree encroachment impact Wyoming pronghorn      (via sciencedaily.com)     Original source 

While Wyoming is home to some of North America's most abundant populations of pronghorn that have largely been stable in recent years, a new analysis shows that many herds are experiencing long-term declines in fawn production.

Severe hurricanes boost influx of juveniles and gene flow in a coral reef sponge      (via sciencedaily.com)     Original source 

A study is the first to evaluate substrate recolonization by sponges in the U.S. Virgin Islands after two catastrophic storms using genetic analyses to understand how much clonality verses sexual recruitment occurs on coral reefs post-storms. Results show that populations of clonal marine species with low pelagic dispersion, such as A. cauliformis, may benefit from increased frequency and magnitude of hurricanes to maintain genetic diversity and combat inbreeding, enhancing the resilience of Caribbean sponge communities to extreme storm events.

Discovery of amino acid unveils how light makes plants open      (via sciencedaily.com)     Original source 

Scientists have uncovered a unique mechanism that regulates the opening of stomata in plants. Phosphorylation of the amino acid Thr881 on the plasma membrane proton pump plays a key role in this process. The study paves the way for the targeted manipulation of plant physiology, with potential applications in agriculture and environmental sustainability.

New roadmap to prevent pandemics centers on protecting biodiversity      (via sciencedaily.com)     Original source 

An international team of 25 scientists has proposed a roadmap for how to prevent the next pandemic by conserving natural areas and promoting biodiversity, thereby providing animals with enough food, safe havens and distance to limit contact and the transfer of pathogens to humans.

Novel electrochemical sensor detects dangerous bacteria      (via sciencedaily.com)     Original source 

Researchers have developed a novel sensor for the detection of bacteria. It is based on a chip with an innovative surface coating. This ensures that only very specific microorganisms adhere to the sensor -- such as certain pathogens. The larger the number of organisms, the stronger the electric signal generated by the chip. In this way, the sensor is able not only to detect dangerous bacteria with a high level of sensitivity but also to determine their concentration.

Seeing the forest for the trees: Species diversity is directly correlated with productivity in eastern U.S. forests      (via sciencedaily.com)     Original source 

When officials make tough calls on which areas to prioritize for conservation, biodiversity is often their top consideration. But there are several types of diversity, and not all of them overlap perfectly. In a new study, researchers analyzed 20-years' worth of U.S. Forest Service data and show that the simplest measure of diversity is the best predictor of healthy forest growth, providing a roadmap for quickly and efficiently protecting ecological resources.

Natural recycling at the origin of life      (via sciencedaily.com)     Original source 

How was complex life able to develop on the inhospitable early Earth? At the beginning there must have been ribonucleic acid (RNA) to carry the first genetic information. To build up complexity in their sequences, these biomolecules need to release water. On the early Earth, which was largely covered in seawater, that was not so easy to do.
