Published Researchers uncover mechanisms behind enigmatic shapes of nuclei
(via sciencedaily.com) Original source White blood cells known as neutrophils feature a nucleus that is structured strikingly different than most nuclei. These unique shapes permit neutrophils to travel all over the body to combat invading pathogens. Scientists have now deciphered the shapeshifting puzzle of the neutrophil nucleus.
Published Microscopy: Overcoming the traditional resolution limit for the fast co-tracking of molecules
(via sciencedaily.com) Original source Researchers have developed an innovative method to simultaneously track rapid dynamic processes of multiple molecules at the molecular scale.
Published Pesticides to help protect seeds can adversely affect earthworms' health
(via sciencedaily.com) Original source While pesticides protect crops from hungry animals, pesky insects, or even microbial infections, they also impact other vital organisms, including bees and earthworms. And today, research reveals that worms are affected by the relatively small amounts of chemicals that can leach out of pesticide-treated seeds. Exposure to nonlethal amounts of these insecticides and fungicides resulted in poor weight gain and mitochondrial DNA (mtDNA) damage in the worms.
Published Female lab mice behave very differently when placed outdoors
(via sciencedaily.com) Original source A new study has examined social behavior of lab mice in large outdoor enclosures.
Published By growing animal cells in rice grains, scientists dish up hybrid food
(via sciencedaily.com) Original source From lab-grown chicken to cricket-derived protein, these innovative alternatives offer hope for a planet struggling with the environmental and ethical impacts of industrial agriculture. Now, scientists add a new recipe to the list -- cultured beef rice -- by growing animal muscle and fat cells inside rice grains. The method results in a nutritious and flavorful hybrid food that, once commercialized, could offer a more affordable protein alternative with a smaller carbon footprint.
Published Benefits of heat pumps
(via sciencedaily.com) Original source Millions of U.S. households would benefit from heat pumps, but the cost of installing the technology needs to come down to make their use a more attractive proposition.
Published CRISPR-copies: New tool accelerates and optimizes genome editing
(via sciencedaily.com) Original source Researchers are further improving CRISPR's versatility to engineer new grasses and yeasts for biochemical production.
Published Eco-friendly way to generate power from waste wood
(via sciencedaily.com) Original source A new study by researchers has revealed a sustainable method of efficiently converting waste heat into electricity using Irish wood products, while minimizing costs and environmental impact.
Published Low-cost microbe can speed biological discovery
(via sciencedaily.com) Original source Researchers have created a new version of a microbe to compete economically with E. coli -- a bacteria commonly used as a research tool due to its ability to synthesize proteins -- to conduct low-cost and scalable synthetic biological experiments.
Published New trial highlights incremental progress towards a cure for HIV-1
(via sciencedaily.com) Original source A new clinical trial suggests that a combination of the drug vorinostat and immunotherapy can coax HIV-infected cells out of latency and attack them. The findings highlight how close -- yet still far -- researchers have come to developing a cure for HIV-1.
Published Sandalwood oil by-product prevents prostate cancer development in mice
(via sciencedaily.com) Original source Sandalwood oil has been used worldwide for centuries. Now, a study is the first to demonstrate in vivo the chemo-preventive properties of a by-product of the oil in a mouse model. Results show administering alpha-santalol reduced visible prostate tumors, protected the normal tissue, and delayed progression from a precancerous condition to a high-grade form of cancer. These findings are significant because mortality in prostate cancer patients is mainly attributable to advanced stages of the disease.
Published Nutrients direct intestinal stem cell function and affect aging
(via sciencedaily.com) Original source The capacity of intestinal stem cells to maintain cellular balance in the gut decreases upon aging. Researchers have discovered a new mechanism of action between the nutrient adaptation of intestinal stem cells and aging. The finding may make a difference when seeking ways to maintain the functional capacity of the aging gut.
Published 3D ice printing can create artificial blood vessels in engineered tissue
(via sciencedaily.com) Original source A new 3D printing method uses ice to build a template for artificial blood vessels in engineered tissue. Researchers hope the vessels could eventually be used in artificial organ transplants or drug testing.
Published How ancient sea creatures can inform soft robotics
(via sciencedaily.com) Original source Fossils of a marine animal that lived 500 million years ago, combined with computer simulations, informed the design of a new soft robot.
Published How electron spectroscopy measures exciton 'holes'
(via sciencedaily.com) Original source Semiconductors are ubiquitous in modern technology, working to either enable or prevent the flow of electricity. In order to understand the potential of two-dimensional semiconductors for future computer and photovoltaic technologies, researchers investigated the bond that builds between the electrons and holes contained in these materials. By using a special method to break up the bond between electrons and holes, they were able to gain a microscopic insight into charge transfer processes across a semiconductor interface.
Published Conversion process turns greenhouse gas into ethylene
(via sciencedaily.com) Original source Engineers have created a more efficient way of converting carbon dioxide into valuable products while simultaneously addressing climate change.
Published Towards A Better Way of Releasing Hydrogen Stored in Hydrogen Boride Sheets
(via sciencedaily.com) Original source Hydrogen stored in hydrogen boride sheets can be efficiently released electrochemically, report scientists. Through a series of experiments, they demonstrated that dispersing these sheets in an organic solvent and applying a small voltage is enough to release all the stored hydrogen efficiently. These findings suggest hydrogen boride sheets could soon become a safe and convenient way to store and transport hydrogen, which is a cleaner and more sustainable fuel.
Published Smart earrings can monitor a person's temperature
(via sciencedaily.com) Original source Researchers introduced the Thermal Earring, a wireless wearable that continuously monitors a user's earlobe temperature. Potential applications include tracking signs of ovulation, stress, eating and exercise. The smart earring prototype is about the size and weight of a small paperclip and has a 28-day battery life.
Published Researchers discover new cell that remembers allergies
(via sciencedaily.com) Original source Researchers have made a groundbreaking discovery: a new cell that remembers allergies.
Published New research uncovers biological drivers of heart disease risk
(via sciencedaily.com) Original source Over the past 15 years, researchers have identified hundreds of regions in the human genome associated with heart attack risk. However, researchers lack efficient ways to explore how these genetic variants are molecularly connected to cardiovascular disease, limiting efforts to develop therapeutics. To streamline analysis of hundreds of genetic variants associated with coronary artery disease (CAD), a team of researchers combined multiple sequencing and experimental techniques to map the relationship between known CAD variants and the biological pathways they impact.
