A new cancer vaccine platform works by enhancing the ability of the immune system to recognize cancer by leveraging anti-viral memories it already has - due to the COVID-19 pandemic, the worst outbreak of the last 70 years.
In popular legend, Lucrezia Borgia, Duchess of Ferrara (1480- 1519), stands falsely accused of poisoning her second husband. Victor Hugo portrayed her in thinly veiled fiction as a tragic femme fatale. Buffalo Bill named his gun after her. But new research by USC historian Diane Yvonne Ghirardo claims that the only sister of Machiavelli's Prince was less interested in political intrigue than in running a business, undertaking massive land development projects that "stand alone in the panorama of early sixteenth-century projects, not only those initiated by women," Ghirardo says.
Attention Deficit/Hyperactivity Disorder (ADHD) is a complex condition considered by some to have both environmental and genetic causes. It is characterized by developmentally inappropriate levels of inattention, hyperactivity and impulsivity that has an onset in childhood. It has become one of the most commonly diagnosed psychiatric diseases, diagnosed in up to 8 percent of children worldwide.
Asteroids are hunks of rock that orbit in the outer reaches of space. Scientists have generally assumed that their small size limited the types of rock that could form in their crusts but two newly discovered meteorites have changed that. The two meteorites were discovered during the Antarctic Search for Meteorites (ANSMET) 2006/2007 field season in a region of the Antarctic ice known as the Graves Nunatak icefield. The light-colored meteorites, designated GRA 06128 and GRA 06129, were immediately recognized as being different from previously known meteorites.
It seems obvious, right? If you are around people who don't think much of you, over time you are more inclined to think less of yourself. That's self esteem. Looking at yourself in the mirror every morning, you never think to question whether the person you see is actually you but our interaction with others impacts that also, claims a PLoS ONE study by Dr Manos Tsakiris in Department of Psychology at Royal Holloway, University of London. He challenges this common-sense notion about our own self image and says that the image we hold of our own face can actually change through shared experiences with other people's faces.
Herbicide use should increase crop yields, that's the whole point, and herbicides and pesticides do that, given the output in food production that has matched the population increases over the last two centuries. But there may be a problem in how some herbicides impact reproduction and tests may not be accounting for that, says a study in the Journal of Environmental Quality.
Scientists can now call up stem cell troops to repair the body using new drug combinations. They have basically 'tricked' bone marrow into releasing extra adult stem cells into the bloodstream, a technique that they hope could one day be used to repair heart damage or mend a broken bone, according to a new study published today in Cell Stem Cell.
A study published in Cancer Prevention Research identifies components of black raspberries with chemopreventive potential. Researchers at the Ohio State Comprehensive Cancer Center found that anthocyanins, a class of flavonoids in black raspberries, inhibited growth and stimulated apoptosis in the esophagus of rats treated with an esophageal carcinogen.
Astronomers say they may have solved one of those classic chicken-and-egg problems, namely, which came first in the early Universe, galaxies or the supermassive black holes seen at their cores.Chris Carilli, of the National Radio Astronomy Observatory (NRAO), outlined the conclusions from recent research done by an international team studying conditions in the first billion years of the Universe's history in a lecture presented to the American Astronomical Society's meeting in Long Beach, California.
NASA's Fermi Gamma-ray Space Telescope has discovered 12 new gamma-ray-only pulsars and has detected gamma-ray pulses from 18 others. The finds are transforming our understanding of how these stellar cinders work."We know of 1,800 pulsars, but until Fermi we saw only little wisps of energy from all but a handful of them," says Roger Romani of Stanford University, Calif. "Now, for dozens of pulsars, we're seeing the actual power of these machines."A pulsar is a rapidly spinning and highly magnetized neutron star, the crushed core left behind when a massive sun explodes. Most were found through their pulses at radio wavelengths, which are thought to be caused by narrow, lighthouse-like beams emanating from the star's magnetic poles.
People have been making cheese for 8,000 years but it seems we still don't know all there is to know about the bacteria responsible for turning milk into cheese. An international research team has identified a new line of bacteria they believe adds flavor to some of the world's most exclusive cheeses.The team used DNA fingerprinting techniques to identify eight previously undiscovered microbes in the French cheese Reblochon.
There are fossils of all shapes and sizes but we like dinosaurs because they're big and that means they could engage in terrific imaginary battles with other big things, like King Kong.You don't see natural history museums vying for fossil skeletons of prehistoric kittens, it's the Tyrannosaurus Rex fossils everyone goes after, whereas non-science people tend to go for little squeaky things they can fit in their laps while they drive and talk on the phone. Earth's creatures come in all sizes, yet we all sprang from the same single-celled organisms that first populated the planet. So how on Earth did life go from bacteria to the blue whale?
Obstructive sleep apnea decreases blood flow to the brain, elevates blood pressure within the brain and eventually harms the brain's ability to modulate these changes and prevent damage to itself, according to a new study published by The American Physiological Society. The findings may help explain why people with sleep apnea are more likely to suffer strokes and to die in their sleep. Sleep apnea is the most commonly diagnosed condition amongst sleep-related breathing disorders and can lead to debilitating and sometimes fatal consequences for the 18 million Americans who have been diagnosed with the disorder. This study identifies a mechanism behind stroke in these patients.
