The mutual neutralization of hydronium and hydroxide      (via sciencedaily.com)     Original source 

Researchers have been able to directly visualize the neutral products of the mutual neutralization of hydronium and hydroxide, and report three different product channels: two channels were attributed to a predominant electron-transfer mechanism, and a smaller channel was associated with proton transfer. The two-beam collision experiment is an important step toward understanding the quantum dynamics of this fundamental reaction.

Researchers overestimate their own honesty      (via sciencedaily.com)     Original source 

The average researcher thinks they are better than their colleagues at following good research practice. They also think that their own research field is better than other research fields at following good research practice. The results point to a risk of becoming blind to one's own shortcomings.

Obesity disrupts normal liver function in mice      (via sciencedaily.com)     Original source 

Your liver plays a vital role in your metabolism, the biological process which converts food into energy. We know that being overweight can negatively affect metabolic activity, but not exactly how. To better understand this, researchers compared the livers of mice which were a typical weight with mice which were obese. They were surprised to find that biological regulation of metabolic activity, after a period of feasting and fasting, was reversed between them. In typical mice, allosteric regulation (the process which controls metabolism) was inhibited during feeding and activated when fasting. However, in obese mice, allosteric regulation increased during feeding and decreased when fasting.

Predatory fish use rapid color changes to coordinate attacks      (via sciencedaily.com)     Original source 

Striped marlin are some of the fastest animals on the planet and one of the ocean's top predators. When hunting in groups, individual marlin will take turns attacking schools of prey fish one at a time. Now a new study helps to explain how they might coordinate this turn-taking style of attack on their prey to avoid injuring each other. The key, according to the new work, is rapid color changes.

Study of 1.2+M births reveals associations between excess heat exposure and preterm births      (via sciencedaily.com)     Original source 

In the face of increasing temperatures globally, a new study of 1.2 million births over two decades has shown a strong association between the risk of pre-term birth and exposure to extreme hot temperatures in the third trimester of pregnancy. The data suggested that this association with extreme temperature might be reduced by the level of greenery in a pregnant person's residential surrounds. The findings suggest health services should consider preparing for an increase in preterm births as our climate warms.

Metal scar found on cannibal star      (via sciencedaily.com)     Original source 

When a star like our Sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it. Now, researchers have found a unique signature of this process for the first time -- a scar imprinted on the surface of a white dwarf star.

The small intestine adapt its size according to nutrient intake      (via sciencedaily.com)     Original source 

Resizing of the intestine is a highly conserved strategy employed by a wide range of organisms to cope with fluctuation in nutrient availability. Nevertheless, very little is known about the mechanisms and signals underlying nutrient-mediated gut resizing. New research has identified one of the signaling pathways implicated in this process.

Cloud clustering causes more extreme rain      (via sciencedaily.com)     Original source 

Understanding cloud patterns in our changing climate is essential to making accurate predictions about their impact on society and nature. Scientists published a new study that uses a high-resolution global climate model to understand how the clustering of clouds and storms impacts rainfall extremes in the tropics. They show that with rising temperatures, the severity of extreme precipitation events increases.

Scientists closer to solving mysteries of universe after measuring gravity in quantum world      (via sciencedaily.com)     Original source 

Scientists are closer to unravelling the mysterious forces of the universe after working out how to measure gravity on a microscopic level. Experts have never fully understood how the force works in the tiny quantum world -- but now physicists have successfully detected a weak gravitational pull on a tiny particle using a new technique.

Global warming increases the diversity of active soil bacteria      (via sciencedaily.com)     Original source 

Warmer soils harbor a greater diversity of active microbes, according to a new study. The study represents a significant shift in our understanding of how microbial activity in the soil influences the global carbon cycle and possible feedback mechanisms on the climate. Until now, scientists have assumed that higher soil temperatures accelerate the growth of microbes, thus increasing the release of carbon into the atmosphere. However, this increased release of carbon is actually caused by the activation of previously dormant bacteria.

Measuring the properties of light: Scientists realize new method for determining quantum states      (via sciencedaily.com)     Original source 

Scientists have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors -- devices that can detect individual light particles -- for so-called homodyne detection. The ability to characterize optical quantum states makes the method an essential tool for quantum information processing.

Barriers against Antarctic ice melt disappearing at the double      (via sciencedaily.com)     Original source 

Undersea anchors of ice that help prevent Antarctica's land ice from slipping into the ocean are shrinking at more than twice the rate compared with 50 years ago, research shows. More than a third of these frozen moorings, known as pinning points, have decreased in size since the turn of the century, experts say. Further deterioration of pinning points, which hold in place the floating ice sheets that fortify Antarctica's land ice, would accelerate the continent's contribution to rising sea levels, scientists warn.

Biomolecular condensates -- regulatory hubs for plant iron supply      (via sciencedaily.com)     Original source 

Iron is a micronutrient for plants. Biologists now show that regulatory proteins for iron uptake behave particularly dynamically in the cell nucleus when the cells are exposed to blue light -- an important signal for plant growth. They found that the initially homogeneously distributed proteins relocated together into 'biomolecular condensates' in the cell nucleus shortly after this exposure.
