On The Origin Of Phobos’ Groovy Mystery

Mars’ natural satellites – Phobos and Deimos – have been a mystery since they were first discovered. While it is widely believed that they are former asteroids that were captured by Mars’ gravity, this remains unproven. And while some of Phobos’ surface features are known to be the result of Mars’ gravity, the origin of its linear grooves and crater chains (catenae) have remained unknown.

SLAC’s high-speed ‘electron camera’ films atomic nuclei in vibrating molecules

An ultrafast “electron camera” at the Department of Energy’s SLAC National Accelerator Laboratory has made the first direct snapshots of atomic nuclei in molecules that are vibrating within millionths of a billionth of a second after being hit by a laser pulse. The method, called ultrafast electron diffraction (UED), could help scientists better understand the role of nuclear motions in light-driven processes that naturally occur on extremely fast timescales

Blood thirsty brains

In a new research collaboration between the University of Witwatersrand and the University of Adelaide, previously held views on the evolutionary development of the human brain are being challenged. The findings of their studies, published today in the Royal Society Open Science *, unseats previous theories that the progression of human intelligence is simply related to the increase in size of the brain. read more

The Great Elephant Census reports massive loss of African savannah elephants

Results of the two-year, $8 million Great Elephant Census (GEC) of African savannah elephants led by Elephants Without Borders (EWB) were released today at an international wildlife conference in Hawaii, confirming massive declines in elephant numbers over just the last decade. The researchers report the current rate of species decline is 8 percent per year, primarily due to poaching

Study documents a lost century for forest elephants

First-ever demographic study confirms forest elephants among the world’s slowest reproducing mammals, spelling trouble for populations threatened by poaching Elephant populations will take nearly a century to recover from poaching since 2002 Closing domestic ivory markets will be debated at upcoming IUCN World Conservation Congress and CITES meeting Forest elephants are one of two species of African elephants read more

CRISPR/Cas9 technology to inactivate cancer mutations

CRISPR/Cas9 is likely one of the most revolutionary tools in biotechnology, with tremendous implications for a broad range of biological and medical disciplines. As programmable scissors this technology allows cleavage of DNA at predefined sites in the genome of cells. Now researchers from the National Center for Tumor Disease (NCT) Dresden, the German Consortium ortium for Translational Cancer Research (DKTK) and the Medical Faculty of the TU Dresden have found a way to utilize the technology to diagnose and inactivate cancer mutations, thereby accelerating cancer research

Monkeys in zoos have human gut bacteria

A new study led by the University of Minnesota shows that monkeys in captivity lose much of their native gut bacteria diversity and their gut bacteria ends up resembling those of humans. The results suggest that switching to a low-fiber, Western diet may have the power to deplete most normal primate gut microbes in favor of a less diverse set of bacteria

Argonne theorists solve a long-standing fundamental problem

Trying to understand a system of atoms is like herding gnats – the individual atoms are never at rest and are constantly moving and interacting. When it comes to trying to model the properties and behavior of these kinds of systems, scientists use two fundamentally different pictures of reality, one of which is called “statistical” and the other “dynamical.” read more
