Why E.T. Would Also Breathe Oxygen

Posted by in category: alien life

As the third most abundant element in the universe, oxygen is both abundant and the best element in the periodic table from which to produce energy for metabolism. That’s one reason planetary scientist David Catling argues that E.T. would also breathe oxygen; as noted in this article blast from the past.

What are the odds that visiting space aliens could simply walk off their craft and start breathing our own oxygen-rich atmosphere?

Better than is generally appreciated; even among some astrobiologists.

Nanoporous Material Displays Odd “Breathing” Habit

Simulation of DUT-49 atom arrangement when it has not contracted. Image: © F.-X. Coudert/CNRSHigh-tech sponges of infinitely small, nanoporous materials can capture and release gaseous or liquid chemicals in a controlled way. A team of French and German researchers from the Institut de Recherche de Chimie Paris (CNRS/Chimie ParisTech) and the Institut Charles Gerhardt de Montpellier (CNRS/Université de Montpellier/ENSCM) has developed and described one of these materials, DUT-49, whose behavior is totally counterintuitive.

When pressure is increased for a sample of DUT-49 to absorb more gas, the material contracts suddenly and releases its contents — as if, when inhaling, the lungs contracted and expelled the air that they contained. This work, published in Nature, makes it possible to envisage innovative behavior in materials science.

Capturing toxic molecules in ambient air, storing hydrogen, targeting drug release — the list of applications that could use flexible nanoporous materials is endless. These materials use the large surface area in their pores to capture and store gaseous or liquid molecules: this phenomenon is called adsorption. Their pores can adsorb impressive quantities of products; they keep getting bigger until they reach their flexibility limit.

FBI Warns of Cyber Threat to Electric Grid

Posted by in categories: cybercrime/malcode, energy, government

Three months after a Department of Homeland Security intelligence report downplayed the threat of a cyber attack against the U.S. electrical grid, DHS and the FBI began a nationwide program warning of the dangers faced by U.S. utilities from damaging cyber attacks like the recent hacking against Ukraine’s power grid.

The nationwide campaign by DHS and the FBI began March 31 and includes 12 briefings and online webinars for electrical power infrastructure companies and others involved in security, with sessions in eight U.S. cities, including a session next week in Washington.

The unclassified briefings are titled “Ukraine Cyber Attack: Implications for U.S. Stakeholders,” and are based on work with the Ukrainian government in the aftermath of the Dec. 23 cyber attack against the Ukrainian power infrastructure.

Scientists are developing graphene solar panels that generate energy when it rains

Posted by in categories: solar power, sustainability

Solar power is making huge strides as a reliable, renewable energy source, but there’s still a lot of untapped potential in terms of the efficiency of photovoltaic cells and what happens at night and during inclement weather. Now a solution has been put forward in the form of producing energy from raindrops.

Key to the new process is graphene: a ‘wonder’ material we’ve heard plenty about before. Because raindrops are not made up of pure water, and contain various salts that split up into positive and negative ions, a team from the Ocean University of China in Qingdao thinks we can harness power via a simple chemical reaction. Specifically, they want to use graphene sheets to separate the positively charged ions in rain (including sodium, calcium, and ammonium) and in turn generate electricity.

Early tests, using slightly salty water to simulate rain, have been promising: the researchers were able to generate hundreds of microvolts and achieve a respectable 6.53 percent solar-to-electric conversion efficiency from their customised solar panel.

Watch SpaceX’s historic ocean landing in crystal-clear 4K

Posted by in categories: drones, robotics/AI, space travel

Still haven’t had enough of SpaceX’s rocket landing in the middle of the ocean? Well, new 4K video is here to satisfy you and then make you hungry for more. Late last night, SpaceX released high-definition footage taken from a chase plane, showing the Falcon 9’s delicate descent onto the autonomous drone ship “Of Course I Still Love You.”

The extra detail gives you a nice glimpse into how the rocket’s legs deployed just prior to landing (and that one of the legs seemed to lag behind the rest). It also shows how the vehicle landed a little off its mark. SpaceX probably didn’t want to show off too much by hitting the bulls eye. That just wouldn’t have been fair.
