Experts from MIT are hosting an event next week to explore the potential blockchain technology could in making electricity markets cleaner and more efficient.

Cambridge chapter of the MIT Enterprise Forum will bring together experts including Joi Ito of the MIT Media Lab and Paul Brody of Ernst and Young for the blockchain transitioning energy industry event on Monday 22 February. They will be joined by a distinguished panel of emerging technology, blockchain, and energy industry leaders to discuss the intersection of energy grid transformation and distributed ledger technology.

Scott Clavenna of Greentech Media will moderate a panel consisting of Joi Ito, Paul Brody, Ed Hesse of Grid Singularity, and Lawrence Orsini of LO3 Energy. The event will tackle questions such as “How can cleantech enterprise and industry leverage the blockchain for innovation?” and “What are the new models for growth?”.

Quantum gravity is a theory that has been the target of decades of study by physicists worldwide. If this idea is proven, it would tie together the General Theory of Relativity (which governs gravitational fields) with quantum mechanics, and the bizarro-world of subatomic particles.

Gravitational waves, produced by accelerating objects, ripple through space-time, according to most interpretations of the General Theory of Relativity penned by famed physicist Albert Einstein. Researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) have announced they detected these disturbances in the fabric of time and space for the first time.

Criminal’s favorite new tool for extortion.


Hollywood Presbyterian Medical Center was the target of a ransomware extortion plot in which hackers seized control of the hospital’s computer systems and then demanded that directors pay in bitcoin to regain access, according to law enforcement sources.

Ransomware attacks on business data systems are becoming an increasingly common form of cyber crime. The assault on Hollywood Presbyterian computers occurred Feb. 5, when hackers prevented hospital staff from accessing patient information, according to law enforcement sources, who were not authorized to discuss the details of the investigation. The hackers then demanded an unspecified sum of computer currency.

But now it seems that collision may have been followed by a bright burst of gamma rays. NASA’s Fermi gamma-ray space telescope detected such an eruption just 0.4 seconds after LIGO’s gravitational waves arrived at Earth. It’s not clear whether the same event triggered both signals, but the Fermi team calculated that the probability of a coincidence was just 0.0022.

The problem is that no one expected such a bright gamma-ray burst to accompany a black-hole merger. Coalescing black holes orbit each other in a cosmic do-si-do, clearing out a region of empty space. According to models of gamma-ray bursts, isolated black holes can’t ignite them.

Strange signal

“Everything smells like a short gamma-ray burst in our signal,” says Valerie Connaughton of the Fermi team. “And that’s a real problem in a way – you don’t expect this signal from merging black holes.”
