Blood tests that track the amount of tumor DNA can - after only one month of drug therapy - detect how well treatment is working in patients with skin cancer, a new study finds.
The online complaint system used by web giants like Google and Twitter is a 'Wild West' with evidence of abuse by complainants, according to a new study from Queen Mary University of London.
Despite this, the UK government is considering promoting similar systems to underpin parts of future web regulation, and the researchers believe this raises questions for its effectiveness.
Over one year, they observed more than 1 billion URLs being complained about, primarily with the intent of removing content.
TALLAHASSEE, Fla. -- When it comes to choosing a mate, female guppies often go for the mates with the flashiest, most interesting color patterns.
But why is that? Turns out, it's all about psychology.
In a new study, Florida State University researchers found that these tiny, tropical fish often choose a mate that physically stands out from the rest of the pack because of a common type of learning called habituation. Through habituation, animals -- in this case guppies -- stop responding to a stimulus after prolonged exposure.
Vanderbilt University paleontologists are looking into the evolutionary origins of the whistles and squeaks that dolphins and porpoises make - part of the rare echolocation ability that allows them to effectively navigate their dark environment.
An innovative use of instruments that measure the ocean near Antarctica has helped Australian scientists to get a clearer picture of how the ocean is melting the Antarctic ice sheet.
Until now, most measurements in Antarctica were made during summer, leaving winter conditions, when the sea freezes over with ice, largely unknown.
Strict policies traditionally embraced by Asian nations to discourage illicit drug use are beginning to change, with a few nations adopting alternative approaches while other nations are taking an even harder line against drugs, according to a new RAND Corporation report.
Thailand is on the forefront of Southeast Asian nations that are reconsidering longstanding policies, moving to adopt greater harm reduction, approving the use of medical cannabis and easing restrictions on the traditional use of the substance kratom.
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.
