A species of aloe believed to be new to science has been found in Somaliland, a self-declared state, internationally considered to be an autonomous region of Somalia. The genus Aloe includes over 600 species, all native to Africa, islands in the western Indian Ocean or the Arabian Peninsula. Its members are succulent plants with densely [...]
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected the chemical fingerprints of sodium chloride (NaCl), potassium chloride (KCl), and their 37Cl and 41K isotopologues, in a high-mass circumstellar disk around Orion Source I, a young, massive star about 1,500 light-years away. To detect molecules in space, astronomers use radio telescopes to search for [...]
A new study published online in the Journal of Experimental Medicine describes how sleep can fight off an infection, whereas other conditions, such as chronic stress, can make the body more susceptible to illness. “Our study shows that sleep has the potential to enhance the efficiency of T cell responses, which is especially relevant in [...]
Those who set realistic goals can hope for a higher level of well-being. The key for later satisfaction is whether the life goals are seen as attainable and what they mean to the person, as psychologists report in a study with over 970 participants.
One of the great mysteries of neuroscience may finally have an answer: Scientists have identified a potential explanation for the mysterious death of specific brain cells seen in Alzheimer's, Parkinson's and other neurodegenerative diseases.
The key to breeding disease-resistant honeybees could lie in a group of genes -- known for controlling hygienic behavior -- that enable colonies to limit the spread of harmful mites and bacteria, according to genomics research. The researchers narrowed in on the 'clean' genes known to improve the colony's chance of survival.
Since the creation of 3D-printed (3DP) porous titanium scaffolds in 2016, the scientific community has been exploring ways to improve their ability to stimulate osteogenesis, or bone remodeling. A recent study revealed the osteogenic potential of Static Magnetic Field (SMF) treatment for human bone-derived mesenchymal stem cells (hBMSCs) using 3DP scaffolds in vitro and in vivo.
Researchers have become the first to describe a model of mitochondrial epilepsy which raises hope for better therapies for patients with this incapacitating condition.Despite the severity of this epilepsy, up to now there have been no animal models available to provide a mechanistic understanding of the condition. That is set to change though as researchers can now explain the important role that astrocytes play in seizure generation.
Researchers have discovered a new mechanism for a class of anti-cancer drugs known as E1 inhibitors. Their findings reveal a novel binding site that will promote drug design of more efficient E1 inhibitors.
Children living in homes with all vinyl flooring or flame-retardant chemicals in the sofa have significantly higher concentrations of potentially harmful semi-volatile organic compounds (SVOCs) in their blood or urine than children from homes where these materials are not present, according to new research.
Australia has the highest rate of mammal extinction in the world. Resettlement of indigenous communities resulted in the spread of invasive species, the absence of human-set fires, and a general cascade in the interconnected food web that led to the largest mammalian extinction event ever recorded. In this case, the absence of direct human activity on the landscape may be the cause of the extinctions, according to an anthropologist.
In two back-to-back symposia a cross-disciplinary cohort of scientists will present the first comprehensive investigations of how humans interacted with plant and animal species in different cultures worldwide through time.
A combination of two drugs -- one of them an immunotherapy agent -- could become a new standard, first-line treatment for patients with metastatic kidney cancer, results from a phase 3 clinical trial suggest.
Cooking, cleaning and other routine household activities generate significant levels of volatile and particulate chemicals inside the average home, leading to indoor air quality levels on par with a polluted major city.
While the polyester leisure suit was a 1970s mistake, polyester and other synthetic fibers like nylon are still around and are a major contributor to the microplastics load in the environment, according to a materials scientist, who suggests switching to biosynthetic fibers to solve this problem.
