Projected loss of brown macroalgae and seagrasses with global environmental change

Sciencedaily.com 

Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role seaweeds and seagrasses in coastal ecosystems and provide evidence of the pervasive impacts of climate change on marine life.

The density difference of sub-Neptunes finally deciphered

Sciencedaily.com 

The majority of stars in our galaxy are home to planets. The most abundant are the sub-Neptunes, planets between the size of Earth and Neptune. Calculating their density poses a problem for scientists: depending on the method used to measure their mass, two populations are highlighted, the dense and the less dense. Is this due to an observational bias or the physical existence of two distinct populations of sub-Neptunes? Recent work argues for the latter.

No more stressing out over structural formulas

Sciencedaily.com 

Structural formulas are a source of dread for many students, but they're an essential tool in biology lessons. A study has now shown that the stress levels of students working with chemical formulas are significantly reduced if they are given simple tips on how to deal with these formulas.

Novel peptide formulation shows promise of treating cognitive decline in schizophrenia

Sciencedaily.com 

Schizophrenia is a serious mental health disorder linked to the imbalance of chemical neurotransmitters that affect cognitive capabilities. Current therapies against schizophrenia have numerous limitations, largely due to the selective permeability of blood-brain barrier, which necessitates the development of novel strategies.

Nike shares tumble on tepid outlook as CEO eyes Olympics marketing win

NAIJ.COM (Nigeria News) 

Nike reported higher profits due to cost-cutting efforts Thursday, but shares fell sharply on the company's tepid outlook despite a hoped-for boost from the upcoming Olympic Games. He also vowed an impressive marketing blitz at the upcoming Olympic Games in Paris.

Long-standing marine mystery solved: How algae get nitrogen to grow

Sciencedaily.com 

Scientists shed light on an unexpected partnership: A marine diatom and a bacterium that can account for a large share of nitrogen fixation in vast regions of the ocean. This symbiosis likely plays a key role for global marine nitrogen fixation and productivity, and thus uptake of carbon dioxide. The newly-discovered bacterial symbiont is closely related to the nitrogen-fixing Rhizobia which live in partnership with many crop plants and may also open up new avenues for engineering nitrogen-fixing plants.

Groundbreaking discovery: Zinc can make crop yields more climate-resilient

Sciencedaily.com 

Climate change, drought, increased temperature and other stressors challenge agricultural sustainability. Researchers have now made an unexpected discovery: zinc plays a pivotal role in the plant response to abiotic stress. This groundbreaking discovery not only sheds light on the intricate mechanisms of plant growth but also holds promise for revolutionizing crop resilience, especially in legume-based agriculture.

Just 4% of teen academy prospects play elite soccer (football)

Sciencedaily.com 

Just four per cent of talented teen academy prospects make it to the top tier of professional football, a new study has shown. A sample of nearly 200 players, aged between 13-18, also revealed only six per cent of the budding ballers even go on to play in lower leagues.

New deep-learning model outperforms Google AI system in predicting peptide structures

Sciencedaily.com 

Researchers have developed a deep-learning model, called PepFlow, that can predict all possible shapes of peptides -- chains of amino acids that are shorter than proteins, but perform similar biological functions. Peptides are known to be highly flexible, taking on a wide range of folding patterns, and are thus involved in many biological processes of interest to researchers in the development of therapeutics.

Emotional overeating fed by temperament, caregivers' reactions to children's emotions

Sciencedaily.com 

A research team tracked children from infancy through age 3 to explore the roots of emotional overeating. Parents/caregivers were surveyed about the children's temperaments and whether they consumed food to manage their emotions. The team found that while emotional overeating was associated with temperament and individuals' capacity to manage their emotions, parents' and caregivers' reactions to the children's negative emotions had a significant impact on whether they developed emotional overeating.

Last surviving woolly mammoths were inbred but not doomed to extinction

Sciencedaily.com 

The last population of woolly mammoths was isolated on Wrangel Island off the coast of Siberia 10,000 years ago, when sea levels rose and cut the mountainous island off from the mainland. A new genomic analysis reveals that the isolated mammoths, who lived on the island for the subsequent 6,000 years, originated from at most 8 individuals but grew to 200--300 individuals within 20 generations. The researchers report that the Wrangel Island mammoths' genomes showed signs of inbreeding and low genetic... Читать дальше...
