Scientists have found that a drug candidate with anticancer potential can be activated by one of the body's natural responses to cellular stress.
Once activated, the agent can kill prostate cancer cells.
The study highlights the potential of the natural compound called leinamycin E1 (LNM) for development as a "prodrug," a medication converted through a metabolic process in the body to become an active therapy.
A study of parental age and autism risk including
5.7 million children in five countries
found increased autism rates among the children of teen moms and among children whose parents have relatively large gaps between their ages. It also confirmed that older parents are at higher risk of having children with autism.
Though previous studies identified a link between advancing parental age and autism risk, many aspects of the association remained unclear. For example, some studies found increased risk with older dads but not moms. The goal of the new study was to determine whether advancing maternal or paternal ages independently increase autism risk, and to what extent each might do so.
Imaging lung cancer requires both precision and innovation and clinical positron emission tomography (PET) imaging reates advanced whole-body parametric maps, which allow quantitative evaluation of tumors and metastases throughout the body, according to research announced at the 2015 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI).
Real-time brain scans coupled with a machine-learning algorithm can reveal whether a person has memory of a particular subject, but with a little bit of concentration people can easily hide their memories from the computer.
But with just a little bit of coaching and concentration, subjects are easily able to obscure real memories, or even create fibs that look like real memories, on brain scans. For cooperative subjects, things are good, but for high-stakes situations knowing they can be spoofed is important.
It all began with an innocuous article on a college news website, penned by a Clemson University student named Mackenzie Pearson.
“The dad bod is a nice balance between a beer gut and working out,” she wrote. “While we all love a sculpted guy, there is just something about the dad bod that makes boys seem more human, natural, and attractive.”
Pearson’s post first made the rounds on social media, before receiving mainstream media attention.-->
Electronic devices that can be injected directly into the brain, or other body parts, have been a staple of science fiction for decades - and they seem a little closer to reality if you visit Charles Lieber's chemistry lab at Harvard.
A team of international researchers, led by Lieber, has developed a method for fabricating nano-scale electronic scaffolds that can be injected via syringe. Once connected to electronic devices, the scaffolds can be used to monitor neural activity, stimulate tissues and even promote regenerations of neurons.
In collaboration with the United States Department of Agriculture, the University of the Basque Country Department of Analytical Chemistry has identified the volatile compounds in damaged walnuts that insects find attractive and which is threatening the harvests of these nuts in California.
These are the first studies carried out on walnuts which are designed to specify the components of the aroma and which can be used to control the moth pests in the most sustainable way, besides helping to cut the use of pesticides and control agents.
Food wasted means money wasted which can be an expensive problem especially in homes with financial constraints. A new study from the Cornell Food and Brand Lab and the Getulio Vargas Foundation, shows that the top causes of food waste in such homes include buying too much, preparing in abundance, unwillingness to consume leftovers, and improper food storage.
"Fortunately," notes lead author Gustavo Porpino, PhD candidate at the Getulio Vargas Foundation and Visiting Scholar at the Cornell Food and Brand Lab, "most of the factors that lead to food waste, can be easily remedied by simple changes in food buying, preparing, and storing."
I’m on the back seat of the lower deck of a number 37 bus, outside the red-brick and Portland stone clock tower of Lambeth Town Hall in Brixton, south London. Although I know exactly where I am, I feel lost. I no longer know whether to trust what my eyes are telling me.
I’ve just been told by a leading vision scientist that I have no real depth perception.
In other words, I have never seen in three dimensions the way most people do.
The World Health Organization released its 2015 updated essential medicines list and for the first time included the progesterone contraceptive vaginal ring (CVR), a contraceptive safe and effective for lactating women in the postpartum period.
The progesterone CVR, developed by the Population Council, is an intravaginal ring that provides women who breastfeed at least four times a day with a contraceptive option as early as four weeks after giving birth. It can be used for up to a year for improved birth spacing.
The central United States has undergone a dramatic increase in seismicity over the past 6 years. From 1973-2008, there was an average of 24 earthquakes of magnitude 3 and larger per year. From 2009-2014, the rate steadily increased, averaging 193 per year and peaking in 2014 with 688 earthquakes. So far in 2015, there have been 430 earthquakes of that size in the central U.S. region through the end of May.
There are many questions and misconceptions about what’s happening. How does the observed increase relate to oil and gas production activities? Does this connect to fracking—more formally known as hydraulic fracturing? What exactly is fracking? What are induced earthquakes?
