March 20, 2019 - Salads were recently in the news--and off America's dinner tables--when romaine lettuce was recalled nationwide. Outbreaks of intestinal illness were traced to romaine lettuce contaminated with Escherichia coli (E. coli) bacteria.
These bacteria occur naturally in the intestines of warm-blooded animals. Because crops are grown in the natural environment, E.coli may get into the fields, contaminating produce. The results are potentially deadly for people who eat that produce.
Labiodental sounds, such as F and V, have been known to be rarely met in hunter-gatherer languages. To understand how this has occurred, the authors undertook a massive statistical inquiry. 2,400 languages were analyzed, and a biomechanical model of mouth and lip movements was created.
Scientists from the National University of Science and Technology "MISIS" developed nanomaterial, which will be able to rstore the internal structure of bones damaged due to osteoporosis and osteomyelitis. A special bioactive coating of the material helped to increase the rate of division of bone cells by 3 times. In the future, it can allow to abandon bone marrow transplantation and patients will no longer need to wait for suitable donor material. An article about the development was published in Applied Surface Science.
Searching high-Tc superconductor has become a hot topic in physics since superconducting mercury was first reported more than one century ago. Dense hydrogen was predicted to metalize and become superconductor at high pressure and room temperature. However, it has been very challenging and no widely accepted experimental work has been reported yet. In 2004, Ashcroft predicted hydrogen-dominant hydrides could become high-Tc superconductor at high pressure, due to the 'chemical precompression'. Later, Drozdov et al.
The ecological bio-production of xylitol and cellulose nanofibers using modified yeast cells, from material produced by the paper industry has been achieved by a Japanese research team. This discovery could contribute to the development of a greener and more sustainable society. The findings were published on March 4, in Green Chemistry.
Freshwater biodiversity is rapidly declining worldwide, and nature-based solutions which increase the resilience of ecological communities are becoming increasingly important in helping communities prepare for the unavoidable effects of climate change.
OAK BROOK, Ill. - The use of digital breast tomosynthesis (DBT), also known as 3-D mammography, may significantly reduce the number of women who undergo breast biopsy for a non-cancerous lesion following an abnormal mammogram, according to a new study published in the journal Radiology.
Unlike standard or full-field digital mammography (FFDM), which captures two x-ray images of the breast from top-to-bottom and from side-to-side, DBT captures multiple images from different angles that are synthesized into 3-D images by a computer.
(Millbrook, NY) In the Americas, primate species likely to harbor Zika - and potentially transmit the virus - are common, abundant, and often live near people. So reports a new study published today in Epidemics. Findings are based on an innovative model developed by a collaborative team of researchers from Cary Institute of Ecosystem Studies and IBM Research through its Science for Social Good initiative.
Stanford researchers have devised a way to generate hydrogen fuel using solar power, electrodes and saltwater from San Francisco Bay.
The findings, published March 18 in Proceedings of the National Academy of Sciences, demonstrate a new way of separating hydrogen and oxygen gas from seawater via electricity. Existing water-splitting methods rely on highly purified water, which is a precious resource and costly to produce.
