May 15, 2019 - We all know plants need nutrients, especially nitrogen and phosphorus. To give crops a boost, they are often put on fields as fertilizer. But we never talk about where the nutrients themselves come from.
Phosphorus, for example, is taken from the Earth, and in just 100-250 years, we could be facing a terrible shortage. That is, unless scientists can find ways to recycle it.
Scientists at Tel Hai College and MIGAL Institute in Israel are working on a way to make phosphorus fertilizer from an unlikely source -- dairy wastewater.
A University of Bristol academic has succeeded where countless cryptographers, linguistics scholars and computer programs have failed - by cracking the code of the 'world's most mysterious text', the Voynich manuscript.
Although the purpose and meaning of the manuscript had eluded scholars for over a century, it took Research Associate Dr. Gerard Cheshire two weeks, using a combination of lateral thinking and ingenuity, to identify the language and writing system of the famously inscrutable document.
Surface engineering of nanocarriers devotes considerable contribution to the field of biomedicine ranging from drug delivery to theranostic. Conventional chemical/physical approaches trend to use PEG functionalization, morphological control, and lipid modification, which allow nanocarriers participate various tasks in complex biological conditions. Although the in-vivo performance of nanocarries was improved by using these aforementioned methods, nanocarriers still suffer from drug delivery barrier caused by immune clearance, resulting in a low therapy efficacy.
Evidence of crawling in an Italian cave system sheds new light on how late Stone Age humans behaved as a group, especially when exploring new grounds, says a study published today in eLife.
In a records review of 290 people at risk for Alzheimer's disease, scientists at Johns Hopkins say they have identified an average level of biological and anatomical brain changes linked to Alzheimer's disease that occur three to 10 years -- some even more than 30 years -- before the disease's first recognizable symptoms appear.
In another major clinical breakthrough of the Walk Again Project, a non-profit international consortium aimed at developing new neuro-rehabilitation protocols, technologies and therapies for spinal cord injury, two patients with paraplegia regained the ability to walk with minimal assistance, through the employment of a fully non-invasive brain-machine interface that does not require the use of any invasive spinal cord surgical procedure. The results of this study appeared on the May 1 issue of the journal Scientific Reports.
Researchers from McLean Hospital and Yale University have published findings of their study of large-scale systems in the brain, findings that could improve understanding of the symptoms and causes of bipolar disorder, schizophrenia, depression, and other mental illnesses.
Scientists might have found an early detection method for some forms of dementia, according to new research by the University of Arizona and the University of Toronto's Baycrest Health Sciences Centre.
According to the study published in the journal Neuropsychologia last month, patients with a rare neurodegenerative brain disorder called Primary Progressive Aphasia, or PPA, show abnormalities in brain function in areas that look structurally normal on an MRI scan.

GPs must be better-equipped to support patients to manage the psychological challenge of reducing their opioid use - according to new research from the University of East Anglia.
The recommendation is part of a toolkit being launched today to help GPs reduce the amount of opioids they prescribe.
The toolkit outlines seven areas of best practice to tackle chronic opioid use - based on international research evidence, the experiences of health organisations and individual practitioners.
New research in The Journal of Physiology has found, using a mouse model, that microbes in the maternal intestine may contribute to impairment of the gut barrier during pregnancy.
Wildfires can have dramatic impacts on Western landscapes and communities, but human values determine whether the changes caused by fire are desired or dreaded. This is the simple - but often overlooked - message from a collaborative team of 23 researchers led by University of Montana faculty in a study published in the May issue of the journal BioScience.
RIVERSIDE, Calif. -- A team of psychologists has found strong associations between working memory -- a fundamental building block of a functioning mind -- and three health-related factors: sleep, age, and depressed mood. The team also reports that each of these factors is associated with different aspects of working memory.
Researchers at Aalto University have discovered a surprising phenomenon that changes how we think about how sound can move particles. Their experiment is based on a famous experiment recognisable from high school science classrooms worldwide - the Chlandni Plate experiment, where particles move on a vibrating surface. The experiment was first performed in from 1787 by Ernst Chladni, who is now known as the father of acoustics. Chladni's experiment showed that when a plate is vibrating at a frequency, heavy particles move towards the regions with less vibration, called nodal lines.
As states crack down on doctor and pharmacy "shopping" by people who misuse opioids, a new study reveals how often those individuals may still be able to find opioids to misuse in their family medicine cabinets.
For every 200 patients prescribed opioids in 2016, one had a family member whose opioid-misuse problem led them to seek the drugs from multiple prescribers and fill prescriptions at multiple pharmacies to avoid detection. If these family members have access to the patient's opioids, this could increase their risk of misuse and possibly overdose.
