Published Giant phage holds promise as treatment for lung infections



Researchers have discovered a new bacterial killer that can target common lung infection caused by Burkholderia bacteria that has exciting potential for biotechnological applications.
Published Plant-based plastic releases nine times less microplastics than conventional plastic



A newly developed plant-based plastic material releases nine times less microplastics than conventional plastic when exposed to sunlight and seawater, a new study has found.
Published Researchers visualize quantum effects in electron waves



One of the most fundamental interactions in physics is that of electrons and light. In an experiment, scientists have now managed to observe what is known as the Kapitza-Dirac effect for the first time in full temporal resolution. This effect was first postulated over 90 years ago, but only now are its finest details coming to light.
Published Discovery could end global amphibian pandemic



A fungus devastating frogs and toads on nearly every continent may have an Achilles heel. Scientists have discovered a virus that infects the fungus, and that could be engineered to save the amphibians.
Published Plastic-free vegan leather that dyes itself grown from bacteria



Researchers have genetically engineered bacteria to grow animal- and plastic-free leather that dyes itself.
Published New discovery unravels malaria invasion mechanism



A recent breakthrough sheds light on how the malaria parasite, Plasmodium falciparum, invades human red blood cells. The study reveals the role of a sugar called sialic acid in this invasion process. The findings have major implications for malaria vaccine and drug development.
Published Water-based paints: Less stinky, but some still contain potentially hazardous chemicals



Choosing paint for your home brings a lot of options: What kind of paint, what type of finish and what color? Water-based paints have emerged as 'greener' and less smelly than solvent-based options. And they are often advertised as containing little-to-no volatile organic compounds (VOCs). But, according to new research, some of these paints do contain compounds that are considered VOCs, along with other chemicals of emerging concern.
Published Scientists further our understanding of how a foodborne bacterium can survive in food preparation environments



Scientists have discovered that bacterial populations remain stable on factory floor despite cleaning efforts in ready-to-eat food production facilities.
Published Chemistry researchers modify solar technology to produce a less harmful greenhouse gas



Researchers are using semiconductors to harvest and convert the sun's energy into high-energy compounds that have the potential to produce environmentally-friendly fuels.
Published Scientists link certain gut bacteria to lower heart disease risk



Changes in the gut microbiome have been implicated in a range of diseases including type 2 diabetes, obesity, and inflammatory bowel disease. Now, a team of researchers has found that microbes in the gut may affect cardiovascular disease as well. The team has identified specific species of bacteria that consume cholesterol in the gut and may help lower cholesterol and heart disease risk in people.
Published Infant gut microbes have their own circadian rhythm, and diet has little impact on how the microbiome assembles



Infant gut microbiomes oscillate with a circadian rhythm, even when they are cultivated outside of the body. Researchers report that the rhythm is detectable as early as 2 weeks after birth but becomes more pronounced with age. The finding comes from a randomized controlled trial that also showed that diet has less impact on the development and composition of the infant microbiome than previously thought.
Published New method reveals hidden activity of life below ground



Researchers have refined an innovative method for measuring the activity level of microbes and linking that to their individual genetic code, providing new insights into the microbial communities that thrive in extreme environments.
Published New antibiotic class effective against multidrug-resistant bacteria



Scientists have discovered a new class of antibiotics with potent activity against multi-drug resistant bacteria, and have shown that it cures bloodstream infections in mice. Two publicly-funded initiatives dedicated to advancing early-stage antibiotic development, ENABLE and ENABLE-2, provided the resources and expert support without which this antibiotic would not have been developed.
Published Engineers 'symphonize' cleaner ammonia production



Among the many chemicals we use every day, ammonia is one of the worst for the atmosphere. The nitrogen-based chemical used in fertilizer, dyes, explosives and many other products ranks second only to cement in terms of carbon emissions, due to the high temperatures and energy needed to manufacture it. But by improving on a well-known electrochemical reaction and orchestrating a 'symphony' of lithium, nitrogen and hydrogen atoms, engineers have developed a new ammonia production process that meets several green targets.
Published When inequality is more than 'skin-deep': Social status leaves traces in the epigenome of spotted hyenas in Tanzania



A research consortium provides evidence that social behavior and social status are reflected at the molecular level of gene activation (epigenome) in juvenile and adult free-ranging spotted hyenas. They analyzed non-invasively collected gut epithelium samples from both high-ranking and low-ranking female hyenas and showed that rank differences were associated with epigenetic signatures of social inequality, i.e., the pattern of activation or switching off of genes that regulate important physiological processes such as energy conversion and immune response in several genome regions.
Published How the Crimean-Congo hemorrhagic fever virus enters our cells



Researchers have identified how the tick-borne Crimean-Congo haemorrhagic fever virus enters our cells. The results are an important step in the development of drugs against the deadly disease.
Published Genomic research may help explain cancer resistance in Tasmanian devils



Through DNA sequencing of Tasmanian devils and their tumors, researchers have tracked the genomic interactions between the animals and the cancer.
Published TB vaccine may enable elimination of the disease in cattle by reducing its spread



Vaccination not only reduces the severity of TB in infected cattle, but reduces its spread in dairy herds by 89%, research finds.
Published Researchers discover key gene for toxic alkaloid in barley



Barley is one of the most important cereal crops on a global scale. Many barley cultivars produce a toxic alkaloid called gramine that affects the suitability of barley as fodder, but also helps to protect barley from pathogens. So far, the potential of manipulating gramine levels has not been harnessed for plant breeding, because the genetic basis of gramine production has been unresolved. Research groups now disclose the complete biosynthetic pathway of gramine and demonstrate how gramine biosynthesis can be introduced into model organisms or removed from barley.
Published Connecting the dots to shape growth forces



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.
