There were 94 total losses reported around the shipping world in 2017, down 4 percent year-on-year, according to Allianz Global Corporate & Specialty SE’s (AGCS) Safety & Shipping Review 2018.
The report indicates that large shipping losses have declined by more than a third (38%) over the past decade and that the downward trend continued into 2017, marking the second lowest losses in 10 years after 2014.
However, Allianz stressed that the sinking of the oil tanker Sanchi and the impact of the NotPetya malware on harbor logistics underline that the shipping sector is being tested by a number of traditional and emerging risk challenges.
A temperature of 130 degrees Fahrenheit (54.4 degrees Celsius) recorded in California’s Death Valley on Sunday by the US National Weather Service could be the hottest ever measured with modern instruments, officials say.
The reading was registered at 3:41 pm at the Furnace Creek Visitor Center in the Death Valley national park by an automated observation system—an electronic thermometer encased inside a box in the shade.
In 1913, a weather station half an hour’s walk away recorded what officially remains the world record of 134 degrees Fahrenheit (56.7 degrees Celsius). But its validity has been disputed because a superheated sandstorm at the time may have skewed the reading.
Microsoft Put Off Fixing Zero Day for 2 Years — Krebs on Security.
A security flaw in the way Microsoft Windows guards users against malicious files was actively exploited in malware attacks for two years before last week, when Microsoft finally issued a software update to correct the problem.
Low levels of total cholesterol (TC) are associated with an increased all-cause mortality risk in both old and younger subjects, but low TC is also found in youth, so which is it? In this video, I present data showing that subjects that had high albumin and HDL, but low TC had a similar survival to subjects that had higher TC levels.
Your typical, run-of-the-mill black holes have long ago been eliminated from the running as candidates for dark matter, that mysterious substance that appears to make up a large proportion of the mass in our universe, including our own galaxy.
The reason is simple: ordinary black holes come from the collapse of stars, which means that they were originally formed from what is called baryonic matter, ordinary matter. You are made of baryons and so are black holes.
While we were all busy watching the Perseverance rover head off on its journey to Mars, NASA’s asteroid sample mission has been gearing up for its big moment. The Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx for short) has completed its final test approach of the surface. The next time it descends, OSIRIS-REx will scoop up pieces of the asteroid Bennu for return to Earth.
NASA launched OSIRIS-REx in 2016, sending it off to intercept 101955 Bennu, a carbonaceous asteroid about 1,610 feet (490 meters) in diameter. Bennu does get very close to Earth at points in its orbit — there’s even a small chance that it could impact the Earth in the next few centuries. Currently, it’s safely out of the way about 2 AU distant (an AU is the distance between Earth and the sun).
OSIRIS-REx rendezvoused with Bennu in 2018, and the team set to work finding a landing zone. NASA encountered the same issue as the Japanese Hayabusa2 team — Bennu was much more craggy than expected. To collect a sample, OSIRIS-REx has to make contact with the surface, and that’s dangerous with uneven surfaces and rocky prominences everywhere. Eventually, NASA selected several potential sites, naming them after birds. The Nightingale site, which is in a crater near the asteroid’s north pole, prevailed.
Although true “cyborgs”—part human, part robotic beings—are science fiction, researchers are taking steps toward integrating electronics with the body. Such devices could monitor for tumor development or stand in for damaged tissues. But connecting electronics directly to human tissues in the body is a huge challenge. Now, a team is reporting new coatings for components that could help them more easily fit into this environment.
The researchers will present their results today at the American Chemical Society (ACS) Fall 2020 Virtual Meeting & Expo.
“We got the idea for this project because we were trying to interface rigid, inorganic microelectrodes with the brain, but brains are made out of organic, salty, live materials,” says David Martin, Ph.D., who led the study. “It wasn’t working well, so we thought there must be a better way.”
The universe may have started with a Big Bang, but it will most likely end in an utterly anticlimactic way, slowly fading to black over trillions and trillions of years. Now, a theoretical physicist at Illinois State University has calculated what might just be the last interesting event that will ever happen – the explosions of stars called black dwarfs, which don’t even exist yet.
The ultimate fate of the universe is still up for debate, but one of the leading hypotheses is that it will undergo a “heat death.” Basically, all the stars will cool down and fizzle out, black holes will evaporate, and the never-ending expansion of the universe will stretch the fabric of reality so far that the remaining subatomic particles will rarely have the chance to whiz within a parsec of each other.
And now, thanks to theoretical physicist Matt Caplan, we have an idea of what might be one of the last things that will ever happen – black dwarf supernovae.
