Published Pollinator's death trap turns into nursery
(via sciencedaily.com) Original source In a group of plants that is famous for luring its pollinators into a death trap, one species offers its flowers as a nursery in exchange. The discovery blurs the line between mutualism and parasitism and sheds light on the evolution of complex plant-insect interactions.
Published Eating too much protein is bad for your arteries, and this amino acid is to blame
(via sciencedaily.com) Original source Consuming over 22% of dietary calories from protein can lead to increased activation of immune cells that play a role in atherosclerotic plaque formation and drive the disease risk, new study showed.
Published Imageomics poised to enable new understanding of life
(via sciencedaily.com) Original source Imageomics, a new field of science, has made stunning progress in the past year and is on the verge of major discoveries about life on Earth, according to one of the founders of the discipline.
Published Viruses that can help 'dial up' carbon capture in the sea
(via sciencedaily.com) Original source Armed with a catalog of hundreds of thousands of DNA and RNA virus species in the world's oceans, scientists are now zeroing in on the viruses most likely to combat climate change by helping trap carbon dioxide in seawater or, using similar techniques, different viruses that may prevent methane's escape from thawing Arctic soil.
Published Link between high levels of niacin -- a common B vitamin -- and heart disease, study suggests
(via sciencedaily.com) Original source Researchers have identified a new pathway that contributes to cardiovascular disease associated with high levels of niacin, a common B vitamin previously recommended to lower cholesterol. The team discovered a link between 4PY, a breakdown product from excess niacin, and heart disease. Higher circulating levels of 4PY were strongly associated with development of heart attack, stroke and other adverse cardiac events in large-scale clinical studies. The researchers also showed in preclinical studies that 4PY directly triggers vascular inflammation which damages blood vessels and can lead to atherosclerosis over time.
Published Giant Antarctic sea spiders reproductive mystery solved
(via sciencedaily.com) Original source Instead of carrying the babies until they hatched, as in most species of sea spiders, one parent (likely the father) spent two days attaching the eggs to the rocky bottom where they developed for several months before hatching as tiny larvae.
Published Mystery solved: The oldest fossil reptile from the alps is an historical forgery
(via sciencedaily.com) Original source Palaeontological analysis shows that a renowned fossil thought to show soft tissue preservation is in fact just paint. The fossil discovered in 1931 was thought to be an important specimen for understanding early reptile evolution. While not all of the celebrated fossil is a forgery, scientists urge caution in how the fossil is utilized in future.
Published Beyond peak season: Bacteria in the Arctic seabed are active all year round
(via sciencedaily.com) Original source Researchers studied the composition and function of bacteria in the seabed off Svalbard, during alternating periods of polar night and midnight sun. To do this, they specially developed a sampling device, the Ellrott grab. In contrast with bacterial communities in the overlying water, the sediment bacteria hardly change with the seasons. This is probably due to the fact that in the seabed some hard-to-digest foods are available all year round.
Published Toxoplasmosis: Evolution of infection machinery
(via sciencedaily.com) Original source Researchers have identified a protein that evolved concurrently with the emergence of cellular compartments crucial for the multiplication of the toxoplasmosis pathogen.
Published Online digital data and AI for monitoring biodiversity
(via sciencedaily.com) Original source Researchers propose a framework for integrating online digital data into biodiversity monitoring.
Published What can bulls tell us about men?
(via sciencedaily.com) Original source Researchers have found genes in the reproductive organs of bulls that influence fertility. The findings can be transferred to humans, as these genes are also present in men.
Published Superbug killer: New synthetic molecule highly effective against drug-resistant bacteria
(via sciencedaily.com) Original source A new antibiotic overcomes antimicrobial resistance mechanisms that have rendered many modern drugs ineffective and are driving a global public health crisis.
Published Discovery of new Li ion conductor unlocks new direction for sustainable batteries
(via sciencedaily.com) Original source Researchers have discovered a solid material that rapidly conducts lithium ions. Consisting of non-toxic earth-abundant elements, the new material has high enough Li ion conductivity to replace the liquid electrolytes in current Li ion battery technology, improving safety and energy capacity. The research team have synthesized the material in the laboratory, determined its structure and demonstrated it in a battery cell.
Published Big new idea introduced with the help of tiny plankton
(via sciencedaily.com) Original source A new model bridges the rules of life at the individual scale and the ecosystem level, which could open new avenues of exploration in ecology, global change biology, and ultimately ecosystem management.
Published Do sugar-free candy and gum give you gas? Researchers think they know why
(via sciencedaily.com) Original source Scientists may have figured out why some people have trouble digesting sorbitol, a sugar alcohol used in sugar-free gum, mints, candy and other products.
Published Researchers shed light on river resiliency to flooding
(via sciencedaily.com) Original source Researchers have completed one of the most extensive river resilience studies, examining how river ecosystems recover following floods. They developed a novel modeling approach that used data from oxygen sensors placed in rivers to estimate daily growth in aquatic plants and algae. The researchers then modeled the algal and plant biomass in 143 rivers across the contiguous U.S. to quantify what magnitude of flooding disturbs the biomass and how long the rivers take to recover from floods. Increased understanding of rivers' resiliency is important to maintaining healthy rivers, as human actions can affect flood regimes and change the conditions in rivers for other aquatic life that may rely on algae and plants as a food source.
Published When it comes to bad breath, some bacterial interactions really stink
(via sciencedaily.com) Original source Researchers found that the oral bacterium Streptococcus gordonii activates another bacterial species, Fusobacterium nucleatum, to produce large quantities of methyl mercaptan, a compound responsible for bad breath. Disrupting this interaction could therefore help treat halitosis, and possibly also help prevent the development of more serious tooth and gum disease.
Published Diving deeper into our oceans: Underwater drones open new doors for global coral reef research
(via sciencedaily.com) Original source Scientists take innovation in coral e-DNA monitoring to the next level.
Published Asexual propagation of crop plants gets closer
(via sciencedaily.com) Original source When the female gametes in plants become fertilized, a signal from the sperm activates cell division, leading to the formation of new plant seeds. This activation can also be deliberately triggered without fertilization, as researchers have shown. Their findings open up new avenues for the asexual propagation of crop plants.
Published Protein-rich breakfast boosts satiety and concentration
(via sciencedaily.com) Original source A new study has explored the link between diet and cognitive function, and the results reveal that a protein-rich breakfast can increase satiety and improve concentration. This is important knowledge in a society with increasing obesity rates and lifestyle-related diseases.
