Algebra Boosts Wireless Network Bandwidth Tenfold

coded-tcp

Algebraists are promising to improve wireless bandwidth by an order of magnitude, not by adding base stations, but by using algebra to eliminate the network-clogging task of resending dropped packets of data. This technology will eliminate wasteful processes and will seamlessly weave data streams from Wi-Fi and LTE, which is a step forward from other […]

New Study Revives Doubted Exoplanet Fomalhaut b

exoplanet Fomalhaut b

A team of astronomers reanalyzed data from NASA’s Hubble Space Telescope to further examine whether the star Fomalhaut hosts a massive exoplanet, named Fomalhaut b, or to see if it is a short-lived dust cloud unrelated to any planet. A second look at data from NASA’s Hubble Space Telescope is reanimating the claim that the […]

Mitochondrial Transfer Technology Could Reduce Risk of Childhood Disease

mitochondrial-dna-swap

New technology that would allow genetic material to shuffle between unfertilized eggs is ready to make healthier babies. This technique would allow parents to minimize the risk of a range of diseases related to defects in mitochondria. The scientists published their findings in the journal Nature. Mitochondrial defects affect 1 in every 4,000 children, and […]

Molecular Nano-Machine Assembly Mimics Human Muscle Movement

molecular-nano-machines

An assembly of thousands of nano-machines has been put together to produce a coordinated contraction movement, extending up to ten centimeters, akin to the movement of muscular fibers. They were synthesized by a CNRS research team from the Institut Charles Sadron. The researchers published their findings in the journal Angewandte Chemie. Nicolas Guiseppone, Université de […]

Fluctuations in Weather Patterns Help Decrease the Antarctic Ozone Hole

Antarctic ozone hole measured this year was the second smallest in the last 20 years

Data from NASA and NOAA satellites show that the average area covered by the Antarctic ozone hole this year was the second smallest in the last 20 years. Scientists believe natural fluctuations in weather patterns played a role in this change. This video shows the status of the ozone hole between July 1, 2012 to […]

Mapping the Human Brain’s Facial Recognition System

fusiform-gyrus-facial-recognition

Humans have evolved an ability to recognize faces, and this ability is so important that there is an area in the brain, the fusiform gyrus, solely dedicated to this task. Brain imaging studies have consistently shown that this region of the temporal lobe becomes active when people look at faces. A new study provides the […]

US Concerns about Biosecurity Could Hamper Collaborations in Viral Research

virologist_using_a_protective_suit

U.S. Federal health agencies have started to tighten security surrounding the research on deadly pathogens. The move is to enhance public safety, but some fear that this might hamper research. Earlier this month, US health agencies added SARS to the list of select agents that pose a sever threat to public health and safety. The […]

Controversy Sparked by Ocean Fertilization Project off Canada’s Coast

haida-trawler-iron-ocean-fertilization

Last July, a chartered fishing boat strewed 100 tonnes of iron sulphate into the ocean, off the western coast of Canada. The goal was to supercharge the marine ecosystem. The iron was supposed to fertilize plankton, boost salmon population and sequester carbon. Currently, it’s still unclear whether the ocean responded as hoped, but this project […]

Keck II Telescope Peers into Uranus’ Depths Using Adaptive-Optics

saturn-hexagonal-pole

These images showcase the fine-scale structure of the atmosphere of Uranus, and contain vastly more detail than other images. The images were taken by the adaptive-optics-equipped telescope, the Keck II, which employed its NIRC2 camera. Near the equator, there is a rhythmic wave structure in a cloud belt. Near the north pole, the mottled texture […]

Cooking Fueled the Growth of the Human Brain

eating-gorilla

A new study has calculated the energetic cost of growing a bigger brain. If humans had been eating a raw food diet exclusively, they would have had to spend more than 9 hours a day eating in order to get enough energy from unprocessed raw food alone to support their large brains. The scientists published […]

New Technique Views Breast Tumors in 3-D with Better Clarity & Reduced Radiation

technique images breast tumors in 3-D

Using phase contrast tomography to X-ray a human breast from multiple angles and by then applying equally sloped tomography, or EST, an international team of scientists were able to produce 3-D images of breast tissue that are sharper than those made using current CT scanners and have a lower dose of X-ray radiation than a […]

Easter Island Moai Statues Could Have “Walked” Out of Quarries

moai-rano-raraku

A controversial new claim made by archaeologists states that the Easter Island moai statues could have walked out of the quarries in which they were made. The archaeologists demonstrated this feat with a 4.4-tonne model. The scientists published their findings in the Journal of Archaeological Science. There are nearly 1,000 statues littering Easter Island’s 163 […]

Scientists Search for Quasar’s “Missing” Galaxy

one of the most distant and brightest quasars in the universe

Scientists are exploring the mystery of a distant and very bright quasar that dates to less than one billion years after the big bang. Hubble astronomers have looked at one of the most distant and brightest quasars in the universe and are surprised by what they did not see: the underlying host galaxy of stars […]

Human Obsession with Orchids Goes as Far Back as Roman Times

orchid-roman-times

A careful study of ancient artifacts in Italy has pushed back the earliest documented appearance of orchids from the Renaissance to Roman times. The orchid’s popularity in public art seemed to decrease with the advent of Christianity, perhaps because of its associations with sexuality. The scientists published their findings in the Journal of Cultural Heritage. […]

Analyzing a Mouse Brain with “Block-Face” Electron Microscopy

analyzing a whole mouse brain under the electron microscope

A team of Scientists at the Max Planck Institute for Medical Research has developed a method for preparing the whole mouse brain for “block-face” electron microscopy, a crucial step towards obtaining a complete circuit diagram of the brain of the mouse. What happens in the brain when we see, hear, think and remember? To be […]

Ankle Bone Fossil of Earliest Primate Implies That It Was Arboreal

purgatorius-tree

It’s always been contentious when primates started climbing trees. The discovery of some new ankle bones is now making it look like primates have always been arboreal. The scientists presented their findings at the annual meeting of the Society of Vertebrate Paleontology in Raleigh, North Carolina, last week. The earliest primate, Purgatorius, a genus of […]

Bees are the world’s most important pollinator, and without them the planet would quickly go hungry. All of over the world, their populations are quickly decreasing, and scientists are trying to find out why. With the widely reported Colony Collapse Disorder, which was due to a disease, finally ebbing down, new research indicates that pesticides […]

Graphene Membranes May be Used to Filter Water & Biological Samples

graphene membranes

Finding that large membranes engineered from single sheets of grapheme allow small molecules to pass through, researchers are now looking to use the graphene membranes as filters for microscopic contaminants in water and to separate specific types of molecules from biological samples. Much has been made of graphene’s exceptional qualities, from its ability to conduct […]
