The Kaikoura earthquake in New Zealand in 2016 caused widespread damage. LMU researchers have now dissected its mechanisms revealing surprising insights on earthquake physics with the aid of simulations carried out on the supercomputer SuperMUC.

The 2016 Kaikoura earthquake (magnitude 7.8) on the South Island of New Zealand is among the most intriguing and best-documented seismic events anywhere in the world – and one of the most complex. The earthquake exhibited a number of unusual features, and the underlying geophysical processes have since been the subject of controversy. LMU geophysicists Thomas Ulrich and Dr. Alice-Agnes Gabriel, in cooperation with researchers based at the Université Côte d’Azur in Valbonne and at Hong Kong Polytechnic University, have now simulated the course of the earthquake with an unprecedented degree of realism. Their model, which was run on the Bavarian Academy of Science’s supercomputer SuperMUC at the Leibniz Computing Center (LRZ) in Munich, elucidates dynamic reasons for such uncommon multi-segment earthquake. This is an important step towards improving the accuracy of earthquake hazard assessments in other parts of the world. Their findings appear in the online journal Nature Communications.

Two isolated mountain lion populations in southern California’s Santa Ana and Santa Monica Mountains are at risk of local extinction, perhaps as soon as within 50 years, according to a study published in the journal Ecological Applications.

The study showed the extinction risk is due to low genetic diversity and mortality that affects the stability of the population. Mountain lion mortality is often caused by humans, but can also result from changes in the environment, such as wildfire and fluctuations in prey density.

Physicists discovered rotating black holes might serve as portals for hyperspace travel. Here’s what would happen if you travel through a black hole.

We have talked about the potential of partial cellular reprogramming in previous articles, and today, we want to draw attention to a new paper that promises to further refine reversal of epigenetic aging in cells.

As we age, our cells experience alterations to their epigenetic markers, and this changes gene expression, which is proposed to be a primary reason we age. Recently, there has been considerable interest in resetting these epigenetic markers to reverse cellular aging, and this paper builds on that.

Three of the study’s authors, Prof. Vittorio Sebastiano, Jay Sarkar, and Marco Quarta, have founded Turn.bio, a biotech company that is working to bring partial cellular reprogramming to humans. The company is also currently enjoying the leadership of Gary Hudson from Oisin Biotechnologies, who is standing in as CEO to help the company get off the ground and funded.

Imagine that… The earth is round.

Many people view pollutants and pathogens as separate causes of illness. However, recent research indicates that the two can interact, changing how people and animals respond to infectious diseases. According to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, environmental pollutants appear to weaken the immune system, reduce vaccine efficacy and increase pathogen virulence.

More than 20 years ago, researchers showed that exposing mice to low levels of a dioxin called 2,3,7,8-tetrachlorodibenzo–p-dioxin made them more susceptible to influenza virus. Since then, several studies have suggested that other chemicals, such as perfluorooctanoic acid, mercury and arsenic, can also alter animals’ immune responses and decrease their resistance to infectious diseases. And epidemiological studies in humans have linked chemical exposure in the womb to a child’s increased risk of infectious disease. However, scientists are only now beginning to unravel how this happens, Senior Editor Britt Erickson writes.

Another anti-aging analytic agency rated David Sinclair number one, but WTF is with his face!?! has a different opinion on how David looks like )

These activity levels “may be easy to achieve by most adults.”

Calyxt is the first with its gene-edited oil, but several other companies also have edited foods in the works.

Featuring titans of Texas medicine, the race was on to develop the cutting-edge technology.
