Published 3D laser printing with bioinks from microalgae (via sciencedaily.com) Original source
Microalgae such as the diatom Odontella aurita and the green alga Tetraselmis striata are especially suitable as 'biofactories' for the production of sustainable materials for 3D laser printing due to their high content in lipids and photoactive pigments. An international research team has succeeded for the first time in manufacturing inks for printing complex biocompatible 3D microstructures from the raw materials extracted from the microalgae.
Published Researchers make breakthrough in understanding species abundance (via sciencedaily.com) Original source
The key finding was that temperature and genome size, not body size, had the greatest influence on the maximum population growth rate of the diatoms. Yet body size still mattered in colder latitudes, conserving Bermann's Rule.
Published Researchers crack a key celiac mystery (via sciencedaily.com) Original source
An interdisciplinary team of medical and engineering researchers has spent the last six years working to unlock a significant piece of the puzzle in the search for a cure: how and where the gluten response begins.
Published Researchers outline promises, challenges of understanding AI for biological discovery (via sciencedaily.com) Original source
Machine learning is a powerful tool in computational biology, enabling the analysis of a wide range of biomedical data such as genomic sequences and biological imaging. But when researchers use machine learning in computational biology, understanding model behavior remains crucial for uncovering the underlying biological mechanisms in health and disease. Researchers now propose guidelines that outline pitfalls and opportunities for using interpretable machine learning methods to tackle computational biology problems.
Published 3D bioprinting advances research on respiratory viruses (via sciencedaily.com) Original source
Researchers develop a microstructured 'artificial lung' model using bioprinting technology.
Published Microscopy technique 'paves way' for improving understanding of cellular functions (via sciencedaily.com) Original source
Scientists have developed a new way of counting labelled proteins in living cells that could become a standard and valuable tool in the field of biomedical research.
Published Recurrent wheezing in children linked to 'silent' viral infections (via sciencedaily.com) Original source
Nearly a quarter of children with recurrent wheezing have 'silent' lung infections that would be better treated with antiviral medications than commonly prescribed steroids that can carry lifelong side effects, new research reveals.
Published Children can inherit early aging symptoms from parents who abuse alcohol, researchers find (via sciencedaily.com) Original source
Researchers say they now know that offspring are inheriting dysfunction in their mitochondria as a result of their parents' substance abuse. This dysfunction causes these individuals to show early signs of age-related disease when they're still considered young, usually in their 40s.
Published Mix of factors prompts owl monkeys to leave their parents (via sciencedaily.com) Original source
There comes a point in the lives of young owl monkeys when they leave their parents and strike out on their own to find a mate. In a new study of a wild population of Azara's owl monkeys in northern Argentina, researchers reveal that a combination of social and ecological factors influences when these tree-dwelling monkeys peel away from their parents and siblings. According to their findings -- which were based on 25 years of genetic and demographic data for several generations of owl monkeys, covering more than 330 individuals -- none of the individuals, regardless of their sex, reproduced in the same group where they were born. In all cases, the researchers found, the animals either departed from their natal group or died before reproducing.
Published How ribosomes in our cells enable protein folding (via sciencedaily.com) Original source
Scientists discovered a role played by ribosomes during the folding of new proteins in cells.
Published Asthma emergencies spike when allergenic pollen blooms (via sciencedaily.com) Original source
A new study that tracks how many asthma-related emergency room visits result from pollen in metropolitan areas highlights the importance of knowing local plants and the need for developing science-based pollen forecasts.
Published Viral defense protein speeds up female stem cell production (via sciencedaily.com) Original source
A viral defense mechanism can be used to accelerate the creation of female stem cell lines in mice. The findings can boost efforts in medical research, drug testing, and regenerative therapies, particularly for women and individuals with two X chromosomes.
Published Do smells prime our gut to fight off infection? (via sciencedaily.com) Original source
In nematodes and humans, mitochondrial stress in the nervous system initiates a whole-body response that is most pronounced in the gut. A recent study showed that in nematodes, the odor of a pathogen triggers the nervous system to broadcast this response to the rest of the organism, prepping mitochondria in intestinal cells to fight a bacterial infection. Humans, too, may be able to sense pathogenic odors that prepare the gut for an infection.
Published Discovering how plants make life-and-death decisions (via sciencedaily.com) Original source
Researchers have discovered two proteins that work in tandem to control an important response to cell stress.
Published Cocaine discovery could pave way for treatment for substance abuse (via sciencedaily.com) Original source
Cocaine binds to a specific transporter in the brain that is responsible for regulating dopamine levels. Researchers have studied and described the process, producing new knowledge that may bring us a step closer to designing a drug for cocaine abuse.
Published Unexpected link between grooming and physiological stress in wild baboons (via sciencedaily.com) Original source
New research has found a surprising link between grooming and physiological stress in wild baboons. While grooming often calms, this study suggests it can sometimes elevate stress levels. This gives us an intriguing look into primate behavior and social dynamics.
Published Fishing is causing frightened fish to flee when they should flirt (via sciencedaily.com) Original source
Populations of squaretail grouper face an uncertain future as new research shows fishing that targets their spawning sites is causing males to be repeatedly scared away from their territories during their short mating meet-ups. By fleeing for safety, individuals are losing valuable time to catch the eye and court female fish.
Published Plants offer fruit to insects to disperse dust-like seeds (via sciencedaily.com) Original source
Fruit exist to invite animals to disperse the swallowed seeds. A research team found that plants targeting insects rather than birds or mammals for this service are more common than previously thought. These plants produce dust-like seeds and fruit suitable for the minute, ground-dwelling animals.
Published Nasal microbiome: Depriving multi-resistant 'bugs' of iron (via sciencedaily.com) Original source
Whether dangerous staphylococci survive in the nose depends on what other bacteria are present -- and how they obtain iron.
Published Elephants on the move: Mapping connections across African landscapes (via sciencedaily.com) Original source
Elephant conservation is a major priority in southern Africa, but habitat loss and urbanization mean the far-ranging pachyderms are increasingly restricted to protected areas like game reserves. The risk? Contained populations could become genetically isolated over time, making elephants more vulnerable to disease and environmental change.
