Two hundred and sixty-one years ago, Linnaeus formalized binomial nomenclature and the modern system of naming organisms. Since the time of his first publication, taxonomists have managed to describe 1.8 million of the estimated 8 to 25 million extant species of multicellular life, somewhere between 7% and 22%. At this rate, the task of treating all species would be accomplished sometime before the year 4,000.
When cells change to a more specialized type, we call this process cellular differentiation. Scientists have revealed that protein secretions by skin cells known as keratinocytes control the differentiation of subsurface skin fat cells. This discovery could potentially help to treat obesity. Associate Professor Takehiko Ueyama and Professor Naoaki Saito at the Biosignal Research Center of Kobe University led the research team, and the findings were published on July 24 in the online edition of the Journal of Investigative Dermatology.
An international team of scientists have observed a previously unclear inflammatory mechanism caused by airborne particles that can worsen asthma symptoms, it has been reported in Toxicological Sciences.
Researchers from the University of Notre Dame and Emory University published a new paper in the Journal of Marketing that examines whether price-based recovery incentives after service failures retain customers in the long run.
The study, forthcoming in the September issue of the Journal of Marketing and titled "The Unintended Consequence of Price-based Service Recovery Incentives," is authored by Vamsi K. Kanuri and Michelle Andrews.
Nearly three years later, it's rare to read a postmortem of the 2016 presidential election that doesn't include at least a passing mention of one of the electorate's more elusive unicorns: the Obama-to-Trump voter.
Ribosomes, the essential machinery used for protein synthesis is recycled after each one round of translation. An enzyme called ABCE1 is responsible for this process and turns out to be remarkably plastic as Ludwig-Maximilians-Universitaet (LMU) in Munich biophysicists report.
Cichlids (Cichlidae) are a group of small to medium-sized fish that are ubiquitous in
freshwater habitats in the tropics. They are particularly notable in exhibiting a wide range of
morphological and behavioral specializations, such as various modes of parental care,
including mouthbrooding. Some species (mainly members of the genus Tilapia) have
achieved fame as culinary delicacies and are of considerable economic significance. Cichlids
have undergone rapid diversification in Africa, which is home to at least 1100 species. This
Immune cells prevent bacteria, parasites or viruses from entering the body when, for example, the intestinal epithelium is injured. They respond with restricted inflammatory reactions, which are controlled via various processes in the healthy organism. If an organism suffers from Crohn's disease, for example, the immune cells are continuously activated. The research group led by Professor Thomas Brunner at the University of Konstanz has demonstrated that the transcription factor LRH-1 plays a key role in immune cells.
Preclinical trials were held on mice. Senior Research Associate Alexander Deneka (Laboratory of Molecular and Biochemical Bases of Pathogenesis and Therapy of Cancer Diseases, Kazan Federal University) explains that the method in question was first proposed by British scientists; they proved that liquid can be drained from a pleural cavity with the help of a talcum powder solution.
Using YouTube to learn about climate-change-related topics will expose you to video content that mostly opposes worldwide scientific consensus.
Inspired by the processes of cellular differentiation observed in developmental biology, an interdisciplinary team of researchers at the University of Bristol have demonstrated a new spontaneous approach to building communities of cell-like entities (protocells) using chemical gradients.
HANOVER, N.H. - July 25, 2019 - Researchers at Dartmouth College have discovered a planet orbiting one of the brightest young stars known, according to a study published in the journal The Astrophysical Journal Letters. Aged at approximately 45 million years old, the star and its planet could provide valuable information on how planetary bodies form.
SILVER SPRING, MD - A Middle East respiratory syndrome coronavirus (MERS CoV) vaccine candidate was shown to be safe, well-tolerated, and induced a robust immune response in a Phase 1 first-in-human clinical trial. Initial findings from the trial were published today in The Lancet Infectious Diseases.
ITHACA, N.Y. - A new study demonstrates that increasing class size has the largest negative impact on female participation in science, technology, engineering and mathematics (STEM) classrooms, and offers insights on ways to change the trend.
Using data obtained from 44 science courses across multiple institutions - including Cornell, the University of Minnesota, Bethel University and American University in Cairo - a team of researchers found that large classes begin to negatively impact students when they reach enrollments over 120 students.
Irvine, Calif., July 24, 2019 -- As Lyme disease increases, researchers have taken a significant step toward finding new ways to prevent its transmission. The experts, who include a pioneer in Lyme disease discovery, have sequenced the genome of the animal carrying the bacteria that causes the illness. The advance by researchers at the University of California, Irvine and colleagues provides a launching pad for fresh approaches to stopping Lyme disease from infecting people.
