Urine is a goldmine of useful substances that can be captured and converted into products such as fertilizer. However, going "green" with urine carries some potential risks. For instance, DNA released from antibiotic-resistant bacteria in urine could transfer resistance to other organisms at the site where the fertilizer is used. Now, research published in ACS' Environmental Science & Technology (ES&T) shows this risk is likely to be minimal.
Researchers at Karolinska Institutet in Sweden have revealed a new principle of organisation which explains how locomotion is coordinated in vertebrates akin to an engine with three gears. The results are published in the scientific journal Neuron.
ANN ARBOR--Recycled and aged human urine can be used as a fertilizer with low risks of transferring antibiotic resistant DNA to the environment, according to new research from the University of Michigan.
It's a key finding in efforts to identify more sustainable alternatives to widely used fertilizers that contribute to water pollution. Their high levels of nitrogen and phosphorus can spur the growth of algae, which can threaten our sources of drinking water.
As more and more large-scale human genome sequencing projects get completed, scientists have been able to trace with increasing confidence both the geographical movements and underlying genetic variation of human populations.
Most of these projects have favored the study of European populations, and thus, have been lacking in representing the true ethnic diversity across the globe.
A pilot study conducted by INRS researchers highlights the effect of chemotherapy on male fertility before and after puberty.
"It is often thought that cancer treatments for prepubescent boys will have no effect on their fertility because their testicles would be "dormant". But in fact, the prepubertal testis are not immune to chemotherapy that affects dividing cells and it is now well recognized that there can be long-term effects," explains Géraldine Delbès, a professor at the Institut National de la Recherche Scientifique (INRS) in Laval.
An international team of researchers from ITMO University, the Australian National University, and Korea University have experimentally trapped an electromagnetic wave in a gallium arsenide nanoresonator a few hundred nanometers in size for a record-breaking time. Earlier attempts to trap light for such a long time have only been successful with much larger resonators. In addition, the researchers have provided experimental proof that this resonator may be used as a basis for an efficient light frequency nanoconverter.
Permafrost, the perennially frozen subsoil in Earth’s northernmost regions, has been collecting and storing plant and animal matter since long before the last Ice Age. The decomposition of some of this organic matter naturally releases carbon dioxide (CO2) into the atmosphere year-round, where it is absorbed by plant growth during the warmer months.
Experts' interest in utilizing gene editing for the breeding crops has seen revolutionary growth. Meanwhile, people's awareness for food safety has also been increasing. To understand the attitudinal difference among experts and public towards gene-edited crops, a team of Japanese researchers, led by Dr.
Reston, VA--Researchers have identified several potentially useful breast cancer biomarkers that indicate the presence and risk of malignancy, according to new research published in the January issue of The Journal of Nuclear Medicine. By comparing healthy contralateral breast tissue of patients with malignant breast tumors and benign breast tumors, researchers found that multiple differences in biomarkers can be assessed with PET/MRI imaging, which could impact risk-adapted screening and risk-reduction strategies in clinical practice.
A new International Osteoporosis Foundation (IOF) position paper reviews experimental and clinical evidence showing that hip bone strength estimated by bone mineral density (BMD) and/or finite element analysis (FEA) reflects the actual strength of the proximal femur.
Researchers at Tohoku University have developed a new type of smart contact lenses that can prevent dry eyes. The self-moisturising system, which is described in the journal Advanced Materials Technologies, maintains a layer of fluid between the contact lens and the eye using a novel mechanism.
Smart contact lenses are wearable devices that could accelerate vision beyond natural human capabilities. They are being developed for a wide range of applications from non-invasive monitoring to vision correction to augmented reality display.
Ocean currents are essential for the global distribution of heat and thus also for climate on earth. For example, oxygen is transferred into the deep sea through the formation of new deep water around Antarctica. Weddell Sea sourced Antarctic Bottom Water (AABW) normally spreads northwards into the South Atlantic and Indian Oceans. However, during the peak of the last two ice ages, the supply of deep water from the Weddell Sea to the South Atlantic Ocean was apparently interrupted, as shown by a new study led by scientists of the GEOMAR Helmholtz Centre for Ocean Research Kiel.
Scientists involved in the Borexino collaboration have presented new results for the measurement of neutrinos originating from the interior of the Earth. The elusive "ghost particles" rarely interact with matter, making their detection difficult. With this update, the researchers have now been able to access 53 events - almost twice as many as in the previous analysis of the data from the Borexino detector, which is located 1,400 metres below the Earth's surface in the Gran Sasso massif near Rome.
WASHINGTON, January 22, 2020 - Since 1880, the Earth's temperature has risen by 1.9 degrees Fahrenheit and is predicted to continue rising, according to the NASA Global Climate Change website. Scientists are actively seeking to understand this change and its effect on Earth's ecosystems and residents.
BINGHAMTON, N.Y. - Your choice of clothing could affect the behavioral habits of wildlife around you, according to a study conducted by a team of researchers, including faculty at Binghamton University, State University of New York.
