A new strain of the bird flu has been identified by researchers that remains powerful after becoming resistant to antiviral drugs.
The findings, published in Nature Communications, reveals how an avian strain of influenza A has emerged that can develop a resistance to antiviral medications. Labeled as H7N9, the mutation that originated in China, has no vaccine to protect patients from the potentially deadly virus.

Named Siats meekerorum, after the man-eating monster from the Ute tribal legend, the fossil belongs to a species of giant meat eaters known as carcharodontosaurs and is the second one discovered in North America.
“This thing is gigantic,” Lindsay Zanno, a paleontologist at North Carolina State University, who discovered the species, said. “There’s simply nothing even close in this ecosystem to the size of this animal that could’ve been interpreted as an apex predator.”

The team used graphene’s mechanical “stretchability” in order to create a voltage controlled oscillator (VCO) – an electronic component that can generate an FM signal. The VCO was used to send and receive audio signals of 100 megahertz. The team used pure tones and more complex music signals to tune the VCO’s output and found that both kinds of signals could be “faithfully reproduced” by an ordinary radio receiver.

The seawater, found 0.6 miles underground is most likely 100 to 145 million years old – a remnant of the Early Cretaceous North Atlantic Sea. The findings support the theory that the North Atlantic Ocean’s transition from a closed basin to open ocean caused saline levels to decrease.

Granite, scientists suggest, could have formed on the Red Planet after large amounts of feldspar were discovered in an ancient volcano.
"We think some of the volcanoes on Mars were sporadically active for billions of years," James Wray, the study’s lead author, said. "It seems plausible that in a volcano you could get enough iterations of that reprocessing that you could form something like granite."

"For the first time, we have direct images of what the Milky Way looked like in the past," study co-leader Pieter G. van Dokkum of Yale University said. "Of course, we can't see the Milky Way itself in the past. We selected galaxies billions of light-years away that will evolve into galaxies like the Milky Way.”

The country’s Pilbara district, home to the world’s oldest rock formations, was found to contain bacterial ecosystems that had never been seen in this area before. The microbially induced sedimentary structures, or MISS, are believed to be 3.5 billion years old. While the cells can no longer be seen under the microscope, there are marks left behind created by large clusters of microbes.

"Since time immemorial, humanity has looked up and wondered what made the man in the moon," Maria Zuber, GRAIL principal investigator from the Massachusetts Institute of Technology in Cambridge said. "We know the dark splotches are large, lava-filled, impact basins that were created by asteroid impacts about four billion years ago. GRAIL data indicate that both the near side and the far side of the moon were bombarded by similarly large impactors, but they reacted to them much differently."

The previously unidentified ligament, named anterolateral ligament or ALL, was found in a broad cadaver study using macroscopic dissection techniques and may play an important role in individuals with anterior cruciate ligament (ACL) tears.

A new study, published Monday in the journal Scientific Reports, sequenced DNA found in pig bones from archaeological sites across Israel. The results found the bones that originated in the early Iron Age, around 900 BC, contained European genetic signatures that continued to dominate the wild boar population in the country.

Nathan Gray, 10, from Nova Scotia, Canada, recently discovered a 600-million-year-old supernova in the galaxy PGC 61330, which lies in the constellation of Draco – beating his sister by 33 days as the youngest person to find a supernova.
Gray made the discovery on October 30 while looking at astronomical images taken by Dave Lane, who runs the Abbey Ridge Observatory (ARO) in Nova Scotia. The Royal Astronomical Society of Canada confirmed Gray’s discovery, but astronomers with the International Astronomical Union say they will need to use a larger telescope to make the finding official.

According to new research by University of Washington climatologist Jim Johnstone, molecules in a redwood tree trunk reflect climate changes experienced throughout the tree’s lifetime.
“This is really the first time that climate reconstruction has ever been done with redwoods,” Johnstone said about the study published in the Journal of Geophysical Research-Biogeosciences.

Swarms of the red and black insects have appeared in Tennessee and northern Alabama. David Cook, a Tennessee entomologist, says the ladybug population has skyrocketed.
"We have perfect weather conditions, and a large food population," Cook said. "This is a perfect insect storm."
