In the boating world, outboard motors reign supreme in terms of portability, ease of maintenance, and better power-to-weight ratio in comparison to their inboard counterparts. However, these design advantages limit the engine’s power output, which is a fair trade-off for the benefit of larger cabin space. That’s the reason why the Lexus LY 650 opted for a 2,700-horsepower (2,013-kilowatt) Volvo inboard engine setup, while the Lamborghini 63 luxury yacht has two V12s integrated within the hull, each making 2,000 hp (1,491 kW). 12 Photos … Source link

Natural gas better than windmills, solar panels In a recent Letter to the Editor,  Fred Roensch accuses me of “sneering at someone’s climate solutions” when in fact, I merely pointed out the negatives that must be weighed against the putative benefits of President Joe Biden’s climate solutions. But since Roensch asked for alternative solutions, here are my suggestions: • Use clean, efficient natural gas to its best advantage, keeping our economy strong, while developing the next generation of technology. • Streamline approvals and encourage further development of modern, small nuclear power stations. • Support energy innovation — cold fusion, molten-salt fission, et al. Solar (1.7% of U.S. energy in 2019) and wind (7%) will never be the solution to the search for… Source link

Columnist Clint argues we must be careful when developing artificial intelligence. The year 2020 was, well, terrible … in many ways. The COVID-19 pandemic brought the entire world to a near standstill, and millions have either been infected or killed by the virus. The economies of many major countries are now in recession, with millions having lost their jobs in the United States alone. And, to top it all off, 2020 was the year we lost one of the greatest musical geniuses of all time — and my personal guitar hero —

Each year, billions of tons of goods are transported globally using cargo containers. Currently, there are concerns that this immense volume of traffic could be exploited to transport illicit nuclear materials, with little chance of detection. One promising approach to combating this issue is to measure how goods interact with charged particles named muons — which form naturally as cosmic rays interact with Earth’s atmosphere. Studies worldwide have now explored how this technique, named ‘muon tomography,’ can be achieved through a variety of detection technologies and reconstruction algorithms. In this article of EPJ Plus, a team headed by Francesco Riggi at the University of Catania, Italy, build on these results to develop a full-scale muon tomograph… Source link

A financially-motivated threat actor notorious for its cryptojacking attacks has leveraged a revised version of their malware to target cloud infrastructures using vulnerabilities in web server technologies, according to new research. Deployed by the China-based cybercrime group Rocke, the Pro-Ocean cryptojacking malware now comes with improved rootkit and worm capabilities, as well as harbors new evasion tactics to sidestep cybersecurity companies’ detection methods, Palo Alto Networks’ Unit 42 researchers said in a Thursday write-up. “Pro-Ocean uses known vulnerabilities to target cloud applications,” the researchers detailed. “In our analysis, we found Pro-Ocean targeting Apache ActiveMQ (CVE-2016-3088), Oracle WebLogic (CVE-2017-10271) and Redis (unsecure instances).” “Once… Source link

The scientific method is built on two pillars: First, the assumption of a common objective reality that separate observers can agree on. Second, the understanding of complex phenomena by isolating simple subsystems for experimental study. In a quantum world, (first) it is provably impossible to separate observer from observed. There is no such thing as objective reality. And (second) it is possible to isolate a particle and do experiments, but most of the interesting quantum effects depend on collective properties of many identical particles that we can never probe by studying one-particle-at-a-time. Since these two pillars of the scientific method fell in the 1920s, scientists continue to think in terms of objective reality, and we continue to analyze pieces to understand the whole…. Source link
