WASHINGTON (AP) — Global warming is shifting the way the Earth wobbles on its polar axis, a new NASA study finds.
Melting ice sheets — especially in Greenland — are changing the distribution of weight on Earth.
And that has caused both the North Pole and the wobble, which is called polar motion, to change course, according to a study published Friday in the journal Science Advances.
Interesting: China wants more cross sharing of Cyber Security information with US. This will only get more interesting with the advancement of Quantum tech.
Article’s headline “Obama warned by China against undermining ‘national security’ interests”.
He made the remarks while addressing the Korean Peninsula situation in separate meetings here with U.S. President Barack Obama and South Korean President Park Geun-hye on the sidelines of the fourth Nuclear Security Summit (NSS).

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.
Such other-worldly “visitors” may not be able to click off the first leg of the New York Marathon, but David Catling, a planetary scientist at the University of Washington in Seattle, argues that it’s likely they would have evolved to use molecular oxygen (O2) for respiratory metabolism.
High-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.
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.
