The Triangulum Stream, Remnant of a Star Cluster Being Ingested by the Milky Way

star clusters in the process of being ingested by the Milky Way

Using the Sloan Digital Sky Survey, a team of scientists have discovered a band of stars, named the Triangulum stream, in the southern Galactic sky that is believed to be the remnant of an ancient star cluster slowly being ingested by the Milky Way. Yale astronomers have caught the Milky Way having a snack. Using […]

Space-Launched Paintballs Could Possibly Deflect an Incoming Asteroid

paint pellets could cause an asteroid to veer off course

The 2012 Move an Asteroid Technical Paper Competition winner, Sung Wook Paek, a graduate student in MIT’s Department of Aeronautics and Astronautics, proposed using a paintball strategy that builds on last year’s competition winner’s idea of deflecting an asteroid with a cloud of solid pellets. In the event that a giant asteroid is headed toward […]

Hubble Views Arbell 2261, An Elliptical Galaxy with an Unusually Large Core

elliptical galaxy Abell 2261

This new image from Hubble shows Abell 2261, a giant elliptical galaxy located about three billion light-years away that is roughly ten times the diameter of our Milky Way with an unusually large core measuring about 10,000 light-years. Astronomers using NASA’s Hubble Space Telescope have obtained a remarkable new view of a whopper of an […]

Genetic Evidence Tracks Missing Otomí During Aztecs Conquest

missing-otomi

In the 15th century, the population of the city state Xaltocan, part of the Otomí, vanished and was replaced by the growing Aztec culture. The fate of the Otomí in the region is known only through conflicting historical accounts and archaeological evidence. A new genetic study has recorded the comings and goings of the Otomí and […]

How Tyrannosaurus Rex Ate Triceratops Horridus

t-rex-eating-t-horridus

Tyrannosaurus rex bite marks have been found on the fossilized bones of Triceratops horridus, but so far such fossils have been studied in an isolated manner. In new research, scientists worked on numerous specimens from Montana’s Hell Creek Formation to identify the tooth marks of T. rex and how it ate T. horridus. The scientists […]

Physical Exercise May Forestall Brain Shrinkage

old-man-cyclilng

Exercising regularly in old age may stop the human brain from shrinking and showing signs of aging better than engaging in mental or social activities. That’s what a new study from Edinburgh University states. This was revealed by combing through the brain scans of 638 people past the age of retirement, who were more physically […]

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

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 […]
