When the zinc and bismuth atoms fused, they produced an atom with 113 protons. This atom decayed, incredibly rapidly, into a series of daughter products, each an alpha particle (two protons and two neutrons) lighter than the parent atom. The daughte
These cognitive functions are known to mature relatively late in humans, after the time of adolescence. Also, this period of persistent myelin development during early adulthood in humans is a time of particular vulnerability to neuropsychiatric d
Alexander says he first found himself floating above clouds before witnessing, "transparent, shimmering beings arced across the sky, leaving long, streamer like lines behind them." He claims to have been escorted by an unknown female companion a
adio dishes in Hawaii, Arizona and California to create a telescope array called the "Event Horizon Telescope" (EHT) that can see details 2,000 times finer than what's visible to the Hubble Space Telescope. These radio dishes were trained on M87,
At our most recent glacial maximum, the Beringia land bridge was likely one thousand miles, from North to South, or roughly the distance from Seattle to San Francisco, spanned between Alaska and Siberia and not covered in ice, as many would imagine.
It is currently very faint because it is out in the depths of space near Jupiter's orbit. But it will steadily brighten over the coming months until it passes less than two million km from the Sun on November 28. That makes it a type of comet cal
He said the way pain worked was very similar in mice and people, so he hoped to develop painkillers that could be used in the clinic. Tests on human cells in the laboratory have also showed the mambalgins have similar chemical effects in people.
published online in Nature Biotechnology, the research team showed for the first time that liver cells, thymus tissue and insulin-producing pancreatic islet cells, in an animal model, can thrive in lymph nodes despite being displaced from their natur
Mr Teitoi said he woke in the afternoon to the sound of scratching and looked overboard to see a six-foot shark circling the boat and bumping the hull. When the shark had his attention it swam off. "He was guiding me to a fishing boat. I looke
Shouhong Wang, a professor in the IU College of Arts and Sciences' Department of Mathematics, and Tian Ma, a professor at Sichuan University, suggest the law of energy and momentum conservation in spacetime is valid only when normal matter, dark mat
Photos and video of Bigfoots exist that are better than the Patterson footage. Photos and video have been shot in the past 20 years that are said to be better than the Patterson footage. They are better than the Patterson footage in that it is cleare
The evolutionary benefit of keeping watch over her descendants may help explain why female killer whales, like humans and pilot whale females, live decades past their reproductive prime. The idea that mothers live much longer than needed for reprodu
Researchers in the US caught pregnant females from two snake species and genetically analysed the litters. That proved the North American pit vipers reproduced without a male, a phenomenon called facultative parthenogenesis that has previously bee
, Kareiva hopes environmental issues will become human issues, incorporated into our basic social, economic, and political fabric. His advice for conservationists? “Don’t be a special interest. We all want a better future
Take it from an international team of physicists, led by the University of Toronto, which used double-sided Scotch tape to give a semiconductor the properties of a high-temperature superconductor. The results of the experiment, published Tuesday i
the scientists found evidence of genetic alterations from BPA exposure. But the truly significant aspect of the study comes from the fact that the researchers replicated in mice the low-level, chronic exposure that humans experience in their day-to-d
Jupiter impacts are of great interest to astronomers, amateur and professional, because they're part of the orbital billiards game that has shaped our solar system. In some cases, the cosmic interloper is destroyed before it has any visible effect o
The first known encounter with Orange Eyes occurred in 1963. According to eyewitness reports, the creature appeared before a plethora of eyewitnesses who described as being approximately 11-feet in height and weighing somewhere in the order of 1,000
But first, an introduction: Scientists have long wondered about the nature of space and time. Albert Einstein envisioned the two concepts as an interwoven fabric that extends smoothly and continuously throughout the universe, warping under the weight
But the latest research shows that the sleep conditioning persists even after they wake up, causing them to sniff strongly or weakly on hearing the relevant tone — even if there was no odour. The participants were completely unaware that they had lea
The work also shows that at least 80 per cent of the human genetic code, or genome, is active. That’s surprisingly high and a sharp contrast to the idea that the vast majority of our DNA is junk. Most people know that DNA contains genes, which hol
The dastardly deed is theoretically possible, however, and even on time scales not stretching into millions of years. "There's one scheme to me that seems not quite plausible, but it's close," said Mike Zarnstorff, an experimental plasma physicis
The work will pay dividends if 54-year-old Meldrum or someone else proves the existence of a bipedal hominid that isn't a human or known primate, something Meldrum thinks will happen in his lifetime. In the meantime, criticism follows.
The jays then gathered around the dead body, forming large cacophonous aggregations. The calls they made, known as "zeeps", "scolds" and "zeep-scolds", encouraged new jays to attend to the dead.
"Because previous studies suggested an affinity between Cerataspis and penaeoid shrimp, and more specifically the family Aristeidae, we sampled heavily within these groups," Crandall explained. His lab had been collecting crustacean DNA informatio
This video by NASA’s Solar Dynamics Observatory captures a dramatic filament eruption on Aug. 31. Shown in the video in extreme ultraviolet light, the filament collapsed and exploded in spectacular fashion. The segment shown in red covers nearly 3 ho
This scenario represents an incomparably more challenging task, since most techniques for studying life were developed using examples existing on Earth. Did the entity use DNA, RNA and proteins to store and utilize genetic information? How can one be
oticed a change in the decay rate of a radioactive sample 39 hours before a solar flare. Since joined by a Purdue University professor of Physics named Ephraim Fischbach, Jenkins' subsequent research has reinforced the discovery, using two samples o
The most recent case was 76-year-old Michael Faherty who died on December 22, 2010. West Galway coroner Ciaran McLoughlin recorded the cause of death as spontaneous human combustion.
"We wanted to examine how the kinds of photos people see every day -- the ones that decorate newspaper or TV headlines, for example -- might produce "truthiness," said lead investigator Eryn J. Newman of Victoria University of Wellington, New Ze
