Published Quantum dots and metasurfaces: Deep connections in the nano world
(via sciencedaily.com) Original source A team has developed printable, highly efficient light-emitting metasurfaces.
Published Scientists engineer yellow-seeded camelina with high oil output
(via sciencedaily.com) Original source Using tools of modern genetics, plant biochemists have produced a new high-yielding oilseed crop variety -- a yellow-seeded variety of Camelina sativa, a close relative of canola, that accumulates 21.4% more oil than ordinary camelina.
Published Virus-like nanoparticles control the multicellular organization and reproduction of host bacteria
(via sciencedaily.com) Original source Researchers have discovered that virus-like nanoparticles can promote the multicellular organization and reproduction of host bacteria. These particles, which are evolutionarily related to phages (viruses that infect bacteria), contain an enzyme that helps shape the multicellular architecture and ultimately enhances morphological differentiation.
Published Algae offer real potential as a renewable electricity source
(via sciencedaily.com) Original source The need to transition away from fossil fuels to more sustainable energy production is critical. That's why a team of researchers is looking at a potential power source that not only produces no carbon emissions but removes carbon as it works: algae.
Published New technique could help build quantum computers of the future
(via sciencedaily.com) Original source Researchers have demonstrated a new method that could enable the large-scale manufacturing of optical qubits. The advance could bring us closer to a scalable quantum computer.
Published Switching nanomagnets using infrared lasers
(via sciencedaily.com) Original source Physicists have calculated how suitable molecules can be stimulated by infrared light pulses to form tiny magnetic fields. If this is also successful in experiments, the principle could be used in quantum computer circuits.
Published Protein study could help researchers develop new antibiotics
(via sciencedaily.com) Original source A team has found a way to make the bacterial enzyme histidine kinase water-soluble, which could make it possible to rapidly screen potential antibiotics that might interfere with its functions.
Published How human derived RNA fragments help the Hepatitis E virus
(via sciencedaily.com) Original source Why does Hepatitis E become chronic in some patients, and why do medications not work? To find out, an international research team led by scientists from Bochum observed a patient with chronic Hepatitis E infection over a year. Repeated sequencing of the virus RNA showed that the virus incorporated various parts of the host's messenger RNA into its genome. This resulted in a replication advantage, which may have contributed to the infection becoming chronic.
Published A protein that enables smell--and stops cell death
(via sciencedaily.com) Original source While smell plays a considerable role in the social interactions of humans -- for instance, signaling fear or generating closeness -- for ants, it is vitally important. Researchers have found that a key protein named Orco, essential for the function of olfactory cells, is also critical for the cells' survival in ants.
Published Fat molecule's inability to bond with shape-shifting protein in cell's powerhouse linked to an inherited metabolic disease
(via sciencedaily.com) Original source By studying mutations in yeast and human cells, scientists say they have found that biochemical bonds between fats and proteins in the mitochondrion, the cell's powerhouse, play a crucial role in how our cells produce energy.
Published Perturbations simplify the study of 'super photons'
(via sciencedaily.com) Original source Thousands of particles of light can merge into a type of 'super photon' under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers have now shown that this exotic quantum state obeys a fundamental theorem of physics. This finding now allows one to measure properties of photon Bose-Einstein condensates which are usually difficult to access.
Published Silkworms help grow better organ-like tissues in labs
(via sciencedaily.com) Original source Biomedical engineers have developed a silk-based, ultrathin membrane that can be used in organ-on-a-chip models to better mimic the natural environment of cells and tissues within the body. When used in a kidney organ-on-a-chip platform, the membrane helped tissues grow to recreate the functionality of both healthy and diseased kidneys.
Published Scientists 'read' the messages in chemical clues left by coral reef inhabitants
(via sciencedaily.com) Original source What species live in this coral reef, and are they healthy? Chemical clues emitted by marine organisms might hold that information. But in underwater environments, invisible compounds create a complex 'soup' that is hard for scientists to decipher. Now, researchers have demonstrated a way to extract and identify these indicator compounds in seawater. They found metabolites previously undetected on reefs, including three that may represent different reef organisms.
Published Determining sex in ants
(via sciencedaily.com) Original source Researchers have been investigating the molecular mechanisms responsible for determining sex in ants. Although the vast majority of an ant colony consists of female workers, males are essential to the continuing survival of the species. In order to uncover the mechanisms involved, the researchers decided to focus on diploid males, which occasionally occur in the Argentine ant.
Published Novel diamond quantum magnetometer for ambient condition magnetoencephalography
(via sciencedaily.com) Original source A highly sensitive diamond quantum magnetometer utilizing nitrogen-vacancy centers can achieve millimeter-scale resolution magnetoencephalography (MEG). The novel magnetometer, based on continuous-wave optically detected magnetic resonance, marks a significant step towards realizing ambient condition MEG and other practical applications.
Published Novel lipopeptide proves lethal against Staphylococcus areus
(via sciencedaily.com) Original source Researchers provide the first insight into the mode of action of the lipopeptide serrawettin W2-FL10, derived from Serratia marcescens. This lipopeptide targets the cell membrane of S. aureus, causing lesions which result in the leakage of intracellular components and ultimately cell death.
Published How milk proteins interact with caffeine in espresso
(via sciencedaily.com) Original source The swirl of milk and espresso -- a small storm in your mug -- doesn't impact the dynamics of the milk proteins, according to research. Researchers took a molecular view of how milk proteins and caffeine molecules interact in water and in a coffee drink. The results suggest that the structures of milk proteins remain intact, meaning they retain their original mouthfeel and taste in your morning brew.
Published New technique reveals how gene transcription is coordinated in cells
(via sciencedaily.com) Original source Researchers invented a technique that allows them to observe which genes and enhancers are active in a cell at the same time. This could help them determine which enhancers control which genes and may reveal potential new drug targets for genetic disorders.
Published Father's diet before conception influences children's health
(via sciencedaily.com) Original source A recent study provides new insights into how fathers' diets and overweight can affect their children's health even before conception. The findings of the study can help develop preventive health measures for men wishing to become fathers: The healthier the father's diet, the lower the risk for their children to develop obesity or diseases such as diabetes later in life.
Published Exercising during pregnancy normalizes eating behaviors in offspring from obese mice
(via sciencedaily.com) Original source Maternal obesity impacts the eating behaviors of offspring via long-term overexpression of the microRNA miR-505-5p, according to a new study.
