	(Sponsor this newsletter) Bizarre Ancient Sea Creature Was Well-Armed for Feeding Tribrachidium was a denizen of the shallow seas about 550 million years ago, during the late Ediacaran period. Oddly, Tribrachidium had three-fold symmetry, meaning three segments  were mirror images of each other. "Because we have no obvious modern comparison, that's made it really hard to work out what this organism was like when it was alive — how it moved, if it moved, how it fed, how it reproduced," said Imran Rahman, a research fellow at the University of Bristol, in the United Kingdom, who led the study. Read More » Hypersonic rocket engine could revolutionize space flight By Matthew and Stock Oxfordshire-based Reaction Engines are developing a new aerospace engine class that combines both jet and rocket technologies. The company recently announced a strategic investment from BAE Systems of 20.6 million pounds ($31.4 million USD), in addition to a grant funding of 60 million pounds ($.4 million USD) from the British government, to accelerate the development of their unique SABRE engine. SABRE, which stands for Synergetic Air-Breathing Rocket Engine, is designed to enable aircraft to operate from a standstill on the runway to hypersonic flight in the atmosphere, and then transition to rocket mode for spaceflight.

"We actually have an animal whose neck is intermediate [in length] — it's a real missing link," said Nikos Solounias, a professor of anatomy at the New York Institute of Technology (NYIT) College of Osteopathic Medicine and the lead researcher on the study. The creature in question — Samotherium major —lived during the Late Miocene in the forested areas of Eurasia, ranging from Italy to China, Solounias said. Read More » 'Spooky Action' Heats Up: Atoms Entangled at Room Temperature The world of the very small can get pretty wacky — particles can be in two or more places at once, and even become entangled, wherein actions on one entity can affect its partners across the cosmos. Physicists have broken all kinds of records in proving the existence of so-called quantum entanglement, and now, they have done it again, coupling together thousands of atoms at room temperature. This new achievement could one day be applied to enable more sensitive magnetic resonance imaging (MRI) scans, superpowerful quantum computers and even unhackable quantum communications networks unhackable by any known current technologies, researchers say.

Using femtosecond laser technology the researchers developed 'Fairy Lights, a system that can fire high frequency laser pulses that last one millionth of one billionth of a second. The pulses respond to human touch, so that - when interrupted - the hologram's pixels can be manipulated in mid-air.

News of the plan comes as more than 150 world leaders arrived in Paris for climate change talks and Chinese President Xi Jinping and U.S. President Barack Obama said they would work together towards striking a deal that moves towards a low-carbon global economy. According to the Xinhau report, the country's first two carbon-monitoring satellites will be ready by next May after four years of development led by Changchun Institute of Optics and Fine Mechanics and Physics, part of China's Academy of Sciences.

Ancient Eggshells Reveal Dinosaur Nesting Behaviors The fragile remains of 150-million-year-old eggshells are helping researchers figure out what kinds of nests dinosaurs created for their eggs, according to a new study. A comprehensive look at 29 types of dinosaur eggs suggests that most dinosaurs buried their eggs in nests covered with dirt and vegetation, a tactic also used by modern-day crocodiles. But some small theropods (mostly meat-eating, bipedal dinosaurs) that were closely related to birds used another strategy: They laid their eggs in open nests, much like most birds do today, the researchers found. Read More » Is Digital Hoarding a Mental Disorder (And Do You Have It)? A man who takes thousands of digital pictures weekly and spends hours every day organizing the photos on his computer could have a condition that, until now, has never been described in medical literature. The patient might have "digital hoarding disorder," according to the authors of a recent report on the man's case. The clutter fills his Amsterdam apartment and prevents him from inviting anyone over to visit, according to the report, which was published Oct. 8 in the journal BMJ Case Reports. Read More » Eyes May Offer Window into Cardiovascular Disease Vision problems may sometimes be the only symptom a person has of a serious cardiovascular condition, a new case report suggests. The man was diagnosed with "amaurosis fugax," a condition in which a person loses vision in one eye, usually for a few minutes at a time, because of an interruption of blood flow in an artery.

In the study, researchers found no difference in birth rates between women who received progesterone treatments during their first trimester of pregnancy and those who received a placebo at that time. Among the women given the supplements, 65.8 percent maintained their pregnancy, compared to 63.3 percent of those given the placebo. Read More » Another American Ebola Survivor Had Eye Problems Ebola survivor Dr. Ian Crozier wasn't the only American to experience eye problems following the disease — a new report describes eye problems in another American doctor who lived through the disease. Dr. Richard Sacra, who works for the Christian mission organization SIM USA, contracted Ebola last year while caring for pregnant women in Liberia during the rise of the Ebola outbreak there. Read More » Why Menstruation Remains a Medical Mystery Humans are among the few species in which the process occurs, and although researchers have ideas about why menstruation happens, there are many unknowns. But a better understanding of the hows and whys of menstruation is needed, researchers say. "There's so much we don't understand about why this repeated event of shedding and repair happens," said Dr. Hilary Critchley, an ob-gyn and reproductive health researcher at the University of Edinburgh in Scotland.

It was covered in barnacles and was initially mistaken for a dead whale. Britain's Maritime and Coastguard Agency said in a statement that a piece of metal alloy was recovered with the help of a local boatman. Read More »

	(Sponsor this newsletter) Massive Rocks May Explain Moon's Mysterious Tilt The mysterious tilt of the moon's orbit is due to gravitational tugs it received from giant, close-passing rocks that eventually slammed into the Earth, new research suggests. The leading explanation for the moon's origin is that a Mars-size rock called Theia struck the newborn Earth about 4.5 billion years ago, and the moon coalesced from the disk of debris that resulted from this crash. However, the moon's current orbit is tilted about 5 degrees with respect to Earth. Read More » 'The Good Dinosaur': Could Humans and Dinos Coexist? What if the dinosaur-killing asteroid never slammed into Earth and the paleo-beasts weren't vanquished from our planet 66 million years ago? The movie maker's answer — that a young Apatosaurus would meet and befriend a cave boy — is cute, but totally off the mark, several paleontologists told Live Science. "It's completely impossible," said Thomas Williamson, curator of paleontology at the New Mexico Museum of Natural History and Science, referring to dinosaurs ever being alive alongside humans — something that could never happen if the dinosaurs were to survive. Read More » The Thanksgiving Sky: The Moon Meets a Bright Star at Dawn As the moon moves around the Earth in its monthly orbit, it often passes in front of background stars. Such events are called "lunar occultations" and one will happen Thursday at dawn in a Thanksgiving lunar treat. Read More » Infections with Mosquito-Borne Chikungunya Virus Can Cause Brain Inflammation, Death Catching the mosquito-borne virus chikungunya usually leads to fever and severe pain, but a new study shows it may also lead to inflammation in the brain, and even death in some people. In the study, researchers looked at an epidemic of the virus on Reunion Island, in the Indian Ocean near Madagascar, that lasted from 2005 to 2006 and sickened 300,000 people. As a result of their infections, 24 people developed encephalitis, which is inflammation of the brain, and four of these people died from their infection. Read More » Liberia Suffers New Ebola Death, Despite Being 'Ebola-Free' The death of a 15-year-old boy from Ebola in Liberia — a country that has been declared free of the disease twice — raises the question of why cases are still popping up in the country, experts say. Although infectious disease experts expect to see new cases crop up shortly after a country is declared Ebola-free — often because of cases that weren't accounted for — in this case, Liberia had gone several months without any new Ebola cases, Adalja said. Liberia was first declared Ebola-free in May, but then a new case was confirmed in July.

The technology utilizes the process of photosynthesis by algae, one of the most common microorganisms on earth, according to a Concordia University engineering professor leading the research. Algae naturally creates electrons during photosynthesis, and metal probes stuck into the plant can capture that energy and transfer it into electricity for batteries, he said on Wednesday.

Like most Americans, NASA astronauts Scott Kelly and Kjell Lindgren have Thanksgiving (Nov. 26) off, and they'll spend the day aboard the International Space Station (ISS) watching football and enjoying a turkey-centric feast, agency officials said. Kelly and Lindgren gave viewers a look at that feast in a special Thanksgiving video this week, breaking out bags of smoked turkey, rehydratable corn, candied yams and potatoes au gratin. Read More »
