Advanced imaging with CT shows that people who cook with biomass fuels like wood are at risk of suffering considerable damage to their lungs from breathing in dangerous concentrations of pollutants and bacterial toxins, according to a new study.
Researchers have developed a tool that allows early detection of shade avoidance syndrome (SAS) in plants using Raman spectroscopy in significantly less time compared to conventional methods. The discovery can help farmers better monitor plant health and lead to improved crop yield.
Researchers have identified a unique population of astrocytes in the dorsal horn of the spinal cord of mice that produces pain hypersensitivity when activated by neurons carrying signals down from the brain. The findings indicate that the role of descending neurons in controlling spinal pain transmission is not limited to suppression and point to this group of astrocytes as a new target for enhancing the effect of chronic pain treatments.
Researchers find that viewing interests as developable, not fixed, can help people make connections among diverse fields that others might miss, with implications for innovation. Their research suggests that understanding this can benefit organizations in generating innovative solutions and ideas, job seekers taking on new or wide-ranging responsibilities, and can create a culture for interdisciplinary learning and problem-solving.
The Loricifera is a microscopic, sediment-dwelling marine invertebrate, with a head covered in over 200 spines and an abdomen with a protective shell - known as a lorica. Since it was first discovered in 1983, just under 40 species have been written about. Now, that number is one more thanks to a group of scientists who reported on a new genus and species of Loricifera.
Physical activity makes happy and is important to maintain psychic health. Researchers studied the brain regions which play a central role in this process. Their findings reveal that even everyday activities, such as climbing stairs, significantly enhance well-being, in particular of persons susceptible to psychiatric disorders.
Scientists have discovered a training method to further improve the delicate touch of pianists by optimizing the method rather than increase the amount of training. They developed a system that freely controls the weight of piano keys using a haptic device, which enables to control the strength and direction of the force. The results of experiments showed that enhancing the somatosensory function of fingertips with AHT could improve the accuracy of keystrokes.
Gut hormones play an important role in regulating fat production in the body. One key hormone, released a few hours after eating, turns off fat production by regulating gene expression in the liver, but this regulation is abnormal in obesity, researchers found in a new study.
Neuroscientists tracked the brains and pupils of self-described basketball fans as they watched March Madness games, to study how people process surprise -- an unexpected change of circumstances that shifts an anticipated outcome. They found that that shifts in the pattern of activity in high-level brain areas only happened at moments that contradicted the watchers' current beliefs about which team was more likely to win.
Products derived from nanotechnology are efficient and highly sought-after, yet their effects on the environment are still poorly understood. A research team has investigated the effects of nanosilver, currently used in almost 450 products for its antibacterial properties, on the algae known as Poterioochromonas malhamensis. The results show that nanosilver disturb the alga's entire metabolism. Its membrane becomes more permeable, the cellular ROS increases and photosynthesis is less effective.
Researchers have determined the three dimensional (3D) structure of a protein responsible for glass formation in sponges. They explain how the earliest and, in fact, the only known natural protein-mineral crystal is formed.
Studies of both mice and humans who have traveled into space reveal that critical parts of a cell's energy production machinery, the mitochondria, can be made dysfunctional due to changes in gravity, radiation exposure and other factors. These findings are part of an extensive research effort across many scientific disciplines to look at the health effects of travel into space.
It is largely unknown why influenza infections lead to an increased risk of bacterial pneumonia. Researchers have now described important findings leading to so-called superinfections, which claim many lives around the world every year.
An international team of researchers from the United Kingdom and China has created droplet-based algal micro-reactors capable of aerobic or hypoxic photosynthesis at room temperature in air. “Our methodology is facile and should be capable of scale-up without impairing the viability of the living cells,” said Professor Xin Huang, a researcher at Harbin Institute of [...]
Despite their reputation, rats are surprisingly sociable and regularly help each other out. Researchers have shown that a rat just has to smell another rat that is engaged in helpful behavior to increase their own helpfulness. This is the first study to show that just the smell of a cooperating rat is enough to trigger a helpful response.
A team of archaeologists from the Israel Antiquities Authority (IAA) has uncovered the remnants of an ancient fortified complex believed to have been founded by the Geshurites, the ally of King David, in the 11th or 10th century BCE. The 3,000-year-old Geshurite fort was unearthed near Hispin, a religious Israeli settlement and a moshav located [...]
