Published Scientists map DNA of Lyme disease bacteria
(via sciencedaily.com) Original source Researchers have produced a genetic analysis of Lyme disease bacteria that may pave the way for improved diagnosis, treatment, and prevention of the tick-borne ailment.
Published Advancing modular quantum information processing
(via sciencedaily.com) Original source A team of physicists envisions a modular system for scaling quantum processors with a flexible way of linking qubits over long distances to enable them to work in concert to perform quantum operations. The ability to carry out such correlated or 'entangling' operations between linked qubits is the basis of the enhanced power quantum computing holds compared with current computers.
Published Diet is main risk factor for colon cancer in younger adults, new study suggests
(via sciencedaily.com) Original source A new study has identified diet-derived molecules called metabolites as main drivers of young-onset colorectal cancer risk, especially those associated with red and processed meat. The report, which analyzed metabolite and microbiome datasets, highlighted that one of the best ways a younger (less than 60 years) adult can prevent colorectal cancer is to discuss their diet with their doctor.
Published A taste for carbon dioxide
(via sciencedaily.com) Original source The remarkable affinity of the microbial enzyme iron nitrogenase for the greenhouse gas CO2 makes it promising for future biotechnologies.
Published New way inflammation impacts cell communication
(via sciencedaily.com) Original source Researchers have made significant progress in understanding how cells communicate during inflammation.
Published Physicists throw world's smallest disco party
(via sciencedaily.com) Original source A new milestone has been set for levitated optomechanics as a group of scientists observed the Berry phase of electron spins in nano-sized diamonds levitated in vacuum.
Published Revealing the mysteries within microbial genomes
(via sciencedaily.com) Original source A new technique will make it much easier for researchers to discover the traits or activities encoded by genes of unknown function in microbes, a key step toward understanding the roles and impact of individual species within the planet's diverse microbiomes.
Published How bread dough gave rise to civilization
(via sciencedaily.com) Original source A major international study has explained how bread wheat helped to transform the ancient world on its path to becoming the iconic crop that today helps sustain a global population of eight billion.
Published Lake Erie walleye growth is driven by parents' size, experience
(via sciencedaily.com) Original source Parent size and the conditions in which actively spawning adults lived are the most influential factors affecting growth of Lake Erie walleye, a new study has found.
Published Hand washing is important -- but is your sink clean?
(via sciencedaily.com) Original source Handbasins are hotspots for dangerous microbes that can cause illnesses including pneumonia, Legionnaires' disease and wound infections, a new study warns. The environmental health study found handbasin biofilms contained a diverse range of pathogens including microbes typically found in water, and other pathogens not found in water.
Published Beige fat cells with a 'Sisyphus mechanism'
(via sciencedaily.com) Original source A new class of fat cells makes people healthier. The cells consume energy and produce heat through seemingly pointless biochemical reactions.
Published A belly full of jelly
(via sciencedaily.com) Original source For a long time, scientists assumed that jellies (commonly known as jellyfish) were a dead-end food source for predatory fish. However, a team has now discovered that fish in Greenland waters do indeed feed on jellyfish. In two of the analyzed species, they even made up the majority of the food. The results suggest that the role of jellyfish as prey in marine food webs should be reconsidered, especially in regards to the fact that they could be profiting from climate change and spreading farther and farther north.
Published Impact of 700 years of Inuvialuit subsistence hunting on beluga whales
(via sciencedaily.com) Original source An international team of researchers analyzed beluga whale bones retrieved from archaeological sites in the Mackenzie Delta, Northwest Territories, Canada, to shed light on the sustainability of centuries of Inuvialuit beluga whale subsistence harvests.
Published New mechanism of action kills cancer cells
(via sciencedaily.com) Original source Conventional cancer drugs work by triggering apoptosis, that is programmed cell death, in tumor cells. However, tumor cells have the ability to develop strategies to escape apoptosis, rendering the drugs ineffective. A research team now describes a new mechanism of action that kills cancer cells through ferroptosis.
Published A ketogenic diet could improve the response to pancreatic cancer therapy
(via sciencedaily.com) Original source Scientists have discovered a way to get rid of pancreatic cancer in mice by putting them on a high fat, or ketogenic, diet and giving them cancer therapy.
Published Decoding the world's largest animal genome
(via sciencedaily.com) Original source Scientists have sequenced the largest genome of all animals, the lungfish genome. Their data help to explain how the fish-ancestors of today's land vertebrates were able to conquer land.
Published Researchers call for genetically diverse models to drive innovation in drug discovery
(via sciencedaily.com) Original source Researchers unveiled an approach to drug discovery that could revolutionize how we understand and treat diseases. Their commentary explains the limitations of studies using traditional mouse models and proposes using genetically diverse mice and mouse and human cells to better predict human responses to drugs and diseases.
Published Newly discovered ability of comammox bacteria could help reduce nitrous oxide emissions in agriculture
(via sciencedaily.com) Original source An international research team has discovered that comammox bacteria, first identified by them in 2015, can grow using guanidine, a nitrogen-rich organic compound, as their sole energy and nitrogen source. This unique ability opens new avenues for targeted cultivation of these enigmatic microbes and could also provide a key to reducing agricultural nitrous oxide emissions.
Published Ecologists put an insect group on century-old map of biodiversity
(via sciencedaily.com) Original source The distribution of species around the globe is not a random process but an outcome resulting from several evolutionary mechanisms as well as past and current environmental limitations. As a result, since the mid-19th century, biologists have identified several main regions, called biogeographic realms, that depict these large ensembles of species around the world. These biogeographic realms represent one of the most fundamental descriptions of biodiversity on Earth and are commonly used in various fields of biology.
Published Exciting advance in stem cell therapy
(via sciencedaily.com) Original source A new technique for mechanically manipulating stem cells could lead to new stem cell treatments, which have yet to fulfill their therapeutic potential.
