Unveiling Mars’ Methane Mystery: Insights from Atmospheric Pressure Fluctuations

Posted by in category: alien life

Is there life on Mars or has life ever existed in its ancient past? What conditions would be the right combination for life to exist there? These questions are what NASA’s Curiosity and Perseverance rovers are trying to answer as they continue to explore the barren and dry landscape of the Red Planet in hopes of unlocking its secrets above or buried deep beneath the surface. One such component that could contribute to life is methane, which has been identified by the Curiosity rover to exist on Mars in bursts. Now, a recent study published in Journal of Geophysical Research Letters: Planets (JGR: Planets) hopes to explain why, how, and when these methane gases reach the surface in bursts. This study holds the potential to help scientists better understand the internal mechanisms of Mars and whether this could lead to life existing on the Red Planet.

2019 news report discussing Curiosity finding methane on Mars.

“Understanding Mars’ methane variations has been highlighted by NASA’s Curiosity team as the next key step towards figuring out where it comes from,” said John Ortiz, who is a PhD Student Researcher at Los Alamos National Laboratory and lead author of the study. “There are several challenges associated with meeting that goal, and a big one is knowing what time of a given sol (Martian day) is best for Curiosity to perform an atmospheric sampling experiment.”

Watch A Tesla Model 3 Casually Blast Through A Flooded Street In San Diego

Posted by in categories: Elon Musk, sustainability, transportation

To make things even more interesting (or weird), there’s a mime (yes, you read that right) in the middle of the street, somehow unfazed by all the surrounding water, who reacts in a way only a mime could (we don’t know what those moves mean, so take that as you may).

Taking both X posts into consideration, there are about 1,000 comments–some say the car would malfunction in a matter of minutes, others say that nothing will happen, while some referred to Elon Musk’s words from 2016 when he said that “the Model S floats well enough to turn it into a boat for short periods of time.”

Inside secret Bond-style Alpine vault ‘backing up Earth’ in case of WW3

Posted by in category: existential risks

Some recent progress on our backup of civilization project …


A SECRET project to back-up planet Earth in the event of apocalypse is underway in a James Bond-style villain bunker in the Swiss Alps.

As a hotbed of conflict explodes around the globe with fears of all-out World War Three mounting, a US firm has installed a British-designed “superman” memory disk containing a compendium of human history.

Signs of ‘transmissible’ Alzheimer’s seen in people who received growth hormone

Posted by in categories: biotech/medical, neuroscience

Evidence that amyloid-beta particles are infectious and cause dementia in rare cases involving people who got growth hormone from cadavers.

Aβ is described as “prion like”…a seed can lead to more Aβ


The findings support a controversial hypothesis that proteins related to the neurodegenerative disease can be ‘seeded’ in the brain through material taken from cadavers.

Recovering lossless propagation: HKU physicists overcoming optical loss in polariton system with synthetic complex frequency waves

Posted by in categories: computing, nanotechnology, physics, security

A collaborative research team co-led by Professor Shuang ZHANG, the Interim Head of the Department of Physics, The University of Hong Kong (HKU), along with Professor Qing DAI from National Center for Nanoscience and Technology, China, has introduced a solution to a prevalent issue in the realm of nanophotonics – the study of light at an extremely small scale. Their findings, recently published in the prestigious academic journal Nature Materials, propose a synthetic complex frequency wave (CFW) approach to address optical loss in polariton propagation. These findings offer practical solutions such as more efficient light-based devices for faster and more compact data storage and processing in devices such as computer chips and data storage devices, and improved accuracy in sensors, imaging techniques, and security systems.

Surface plasmon polaritons and phonon polaritons offer advantages such as efficient energy storage, local field enhancement, and high sensitivities, benefitting from their ability to confine light at small scales. However, their practical applications are hindered by the issue of ohmic loss, which causes energy dissipation when interacting with natural materials.

Over the past three decades, this limitation has impeded progress in nanophotonics for sensing, superimaging, and nanophotonic circuits. Overcoming ohmic loss would significantly enhance device performance, enabling advancement in sensing technology, high-resolution imaging, and advanced nanophotonic circuits.
