Scientists have reported that an experimental vaccine targeting one of the most common genetic drivers of pancreatic cancer, called mutant KRAS, is safe and generated a durable immune responses aimed at preventing the cancer.
America leads the world in adult science literacy, science output and social media. That means broad social networks.
And it means, unless some field of science is your particular hot-button issue, the US is doing better in science acceptance than every other country, and spending time and money doing awareness is not really helping much.
Facial recognition software works pretty well. It measures various parameters, such as the distance between the person's eyes, the height from lip to top of their nose and various other metrics and then compares it with photos of people in a database.
Why not create emotion recognition software that can use its own custom parameters?
Dev Drume Agrawal, Shiv Ram Dubey and Anand Singh Jalal of the GLA University, in Mathura suggest in the International Journal of Computational Vision and Robotics
has taken a three-phase approach to a software emotion detector.
A team of researchers has developed a new model to study the motion patterns of bacteria in real time and to determine how these motions relate to communication within a bacterial colony.
The researchers chemically attached colonies of Escherichia coli bacteria to a microcantilever – a microscopic beam anchored at one end, similar to a diving board – thus coupling its motion to that of the bacteria. As the cantilever itself isn't doesn't generate any vibrations, or 'noise,' this allowed the researchers to monitor the colony's reactions to various stimuli in real time.
For lovers of wild foods, autumn means things like mushrooms and fungi of dizzying variety.
Intrepid treasure hunters scour the woods in search of delectable wild mushrooms and their not-quite-meat, not-quite-vegetable qualities.
A bonus: If you find some, you may be eating something not even known to science.
The Fungi Kingdom is enormously diverse and completely under-documented. Species are tough to know, and that is without counting the billions that have gone extinct without us ever knowing about them, but of the 10 million species likely out there, only about 100,000 have been described.
That DNA makes RNA which makes protein is a simplified explanation molecular biologists use to explain for how genetic information is deciphered and translated in living organisms.
The process is more complicated than the schema first articulated nearly 60 years ago by Nobel Laureate Francis Crick, co-discoverer of the DNA's double-helix structure. Now it is known that there are multiple types of RNA, three of which—messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA)—are essential for proper protein production. Moreover, RNAs that are synthesized during the process known as transcription often undergo subsequent changes, which are referred to as "post-transcriptional modifications."
If we get sugars down to 3% of total energy intake, it may put dentists out of business, according to a paper in BMC Public Health which analyzed the effect of sugars on tooth decay and found that sugars are the only cause of tooth decay in children and adults.
Free sugars are defined by the World Health Organisation Nutrition Guidance Advisory Group as "Free sugars include monosaccharides and disaccharides added to foods by the manufacturer, cook or consumer, and sugars naturally present in honey, syrups, fruit juices and fruit concentrates."
Calculating the pros and cons is a time-honored method for making analytical decisions but focusing too much on numberscalculations, especially those involving money, can lead to negative consequences, including social and moral transgressions, says a new paper.
Based on several experiments, researchers concluded that people in a "calculative mindset" as a result of number-crunching are more likely to analyze non-numerical problems mathematically and not take into account social, moral or interpersonal factors.

Molecules containing carbon-halogen bonds are produced naturally across all kingdoms of life and constitute a large family of natural products with a broad range of biological activities.
The presence of halogen substituents in many bioactive compounds has a profound influence on their molecular properties and a goal of chemical science has been to find the late-stage, site-specific incorporation of a halogen atom into a complex natural product by replacing an sp³ C-H bond (one of the most inert chemical bonds known in an organic compound) with a C-X bond (X=halogen).
There has been no reliable synthetic or biological method known to be able to achieve this type of transformation but in Nature Chemical Biology
In 2010, McGill Redmen receiver Charles-Antoine Sinotte suffered a concussion during his last home game. "It was like nothing I had experienced before," recalls Sinotte. "I felt like I was out of my body."
Although he received medical attention and missed the rest of the game, he admits he downplayed his symptoms in order to play in the next game – his last before leaving McGill.
Researchers have discovered "the most famous wheat gene," a reproductive traffic cop of sorts that can be used to transfer valuable genes from other plants to wheat, which clears the way for wheat varieties with disease- and pest-resistance traits of other grasses.
Though it would be genetic modification, because of precise legal definitions that ban some genetic optimization but allow mutagenesis and other older forms of genetic modification, it would not have the same regulatory hurdles and controversy of modern GMOs.
Men who had moderate baldness affecting both the front and the crown of their head by age 45 were at a 40% increased risk of developing aggressive prostate cancer than men with no baldness, according to a new, large cohort analysis from the prospective Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial.
Prostate cancer is the second most common cancer among men.
Aggressive prostate cancer usually indicates a faster growing tumor resulting in poorer prognosis relative to non-aggressive prostate cancer later in life. There was no significant link between other patterns of baldness and prostate cancer risk.
The use of unnecessary medical tests and procedures driven by a fear of malpractice lawsuits, commonly known as 'defensive medicine', has been estimated to cost up to $46 billion annually in the U.S.
It used to be that we didn't want medical decisions being made by insurance companies, and instead they became dictated by lawyers.
For a recent paper, the authors estimated the cost of defensive medicine on three services – tests, procedures or hospitalizations – by asking physicians to estimate the defensiveness of their own orders. The authors invited 42 hospital physicians to complete a survey, which 36 physicians did and rated 4,215 orders for 769 patients in the research letter.
