Published Hybrid transistors set stage for integration of biology and microelectronics



Researchers create transistors combining silicon with biological silk, using common microprocessor manufacturing methods. The silk protein can be easily modified with other chemical and biological molecules to change its properties, leading to circuits that respond to biology and the environment.
Published How do temperature extremes influence the distribution of species?



As the planet gets hotter, animal and plant species around the world will be faced with new, potentially unpredictable living conditions, which could alter ecosystems in unprecedented ways. A new study investigates the importance of temperature in determining where animal species are currently found to better understand how a warming climate might impact where they might live in the future.
Published Nutrient found in beef and dairy improves immune response to cancer



Trans-vaccenic acid (TVA), a long-chain fatty acid found in meat and dairy products from grazing animals such as cows and sheep, improves the ability of CD8+ T cells to infiltrate tumors and kill cancer cells, according to a new study.
Published Researchers puncture 100-year-old theory of odd little 'water balloons'



Quinoa and many other extremely resilient plants are covered with strange balloon-like 'bladders' that for 127 years were believed to be responsible for protecting them from drought and salt. Research results reveal this not to be the case. These so-called bladder cells serve a completely different though important function. The finding makes it likely that even more resilient quinoa plants will now be able to be bred, which could lead to the much wider cultivation of this sustainable crop worldwide.
Published Team discovers rules for breaking into Pseudomonas



Researchers report that they have found a way to get antibacterial drugs through the nearly impenetrable outer membrane of Pseudomonas aeruginosa, a bacterium that -- once it infects a person -- is notoriously difficult to treat.
Published Skunks' warning stripes less prominent where predators are sparse, study finds



Striped skunks are less likely to evolve with their famous and white markings where the threat of predation from mammals is low, scientists have discovered.
Published First comprehensive look at effects of 2020-2021 California megafires on terrestrial wildlife habitat



In 2020 and 2021, California experienced fire activity unlike anything recorded in the modern record. When the smoke cleared, the amount of burned forest totaled ten times more than the annual average going back to the late 1800s. We know that wildlife in western forests evolved with changing habitat and disturbances like wildfire. Each species responds differently, some benefiting from openings, others losing critical habitat. What we don't know is how increasing fire severity at large scales is impacting their habitat and survival, because many species are not adapted to these types of 'megafires.'
Published A stronger core for better plant breeding



A new software tool with enhanced genome-sequencing powers has been developed, increasing the speed and accuracy at which researchers can improve plants through breeding.
Published Curators and cavers: How a tip from a citizen scientist led to deep discoveries in Utah's caves



Scientists and colleagues from Utah's caving community have published the first research from their collaborative fieldwork effort deep in Utah's caves. The journal's feature article reveals why caves make such compelling research archives; what was uncovered in Boomerang Cave in northern Utah; why skeletal remains provide new access to hard-to-get data from the recent past; and offers a new zoological baseline for mammalian changes in an alpine community.
Published Sophisticated swarming: Bacteria support each other across generations



When bacteria build communities, they cooperate and share nutrients across generations. Researchers have been able to demonstrate this for the first time using a newly developed method. This innovative technique enables the tracking of gene expression during the development of bacterial communities over space and time.
Published Tiny beads preserve enzymes for biocatalysis



Some enzymes, such as the one derived from fungi and investigated in this study, are able to produce valuable substances such as the fragrance (R)-1-phenylethanol. To this end, they convert a less expensive substrate using a co-substrate. A research team came up with the idea of supplying them with this co-substrate using a plasma -- a somewhat crazy idea, as plasmas generally have a destructive effect on biomolecules. However, by employing several tricks, the researchers did indeed succeed. They have now refined one of these tricks and thus improved the process: They attach the enzymes to tiny beads in order to hold them in place at the bottom of the reactor, where they are protected from the damaging effects of the plasma.
Published Trilobites rise from the ashes to reveal ancient map



Ten newly discovered species of trilobites, hidden for 490 million years in a little-studied part of Thailand, could be the missing pieces in an intricate puzzle of ancient world geography.
Published Looking for 'LUCA' and the timing of cellular evolution



LUCA, the 'last universal common ancestor' of all living organisms, lived 4.32 to at most 4.52 billion years ago. What LUCA looked like is unknown, but it must have been a cell with among others ribosomal proteins and an ATP synthase.
Published Laser-powered 'tweezers' reveal universal mechanism viruses use to package up DNA



Researchers have used laser-powered ‘optical tweezers’ to reveal a universal motor mechanism used by viruses for packaging their DNA into infectious particles.
Published How gut microbes help alleviate constipation



Scientists have identified the genes in the probiotic Bifidobacteria longum responsible for improving gut motility. A research team found that B. longum strains possessing the abfA cluster of genes can ameliorate constipation through enhanced utilization of an indigestible fiber called arabinan in the gut.
Published Deep-sea mining and warming trigger stress in a midwater jellies



The deep sea is home to one of the largest animal communities on earth which is increasingly exposed to environmental pressures. However, our knowledge of its inhabitants and their response to human-induced stressors is still limited. A new study now provides first insights into the stress response of a pelagic deep-sea jellyfish to ocean warming and sediment plumes caused by deep-sea mining.
Published Could eating turkey ease colitis?



According to data in mice, extra tryptophan could reduce the risk of future colitis flares.
Published Unearthing how a carnivorous fungus traps and digests worms



A new analysis sheds light on the molecular processes involved when a carnivorous species of fungus known as Arthrobotrys oligospora senses, traps and consumes a worm.
Published Bacteria store memories and pass them on for generations



Scientists have discovered that bacteria can create something like memories about when to form strategies that can cause dangerous infections in people, such as resistance to antibiotics and bacterial swarms when millions of bacteria come together on a single surface. The discovery -- which has potential applications for preventing and combatting bacterial infections and addressing antibiotic-resistant bacteria -- relates to a common chemical element bacterial cells can use to form and pass along these memories to their progeny over later generations.
Published Coffee grounds may hold key to preventing neurodegenerative diseases



A team of researchers found that caffeic-acid based Carbon Quantum Dots (CACQDs), which can be derived from spent coffee grounds, have the potential to protect brain cells from the damage caused by several neurodegenerative diseases.
