Sunscreen Required to Survive
I fear that some Neanderthols may have survived and that their decedents live among us. -

German Tourists Hit by Songthaew While Using Zebra Crossing in Khao Lak
That's a tough sell. They never admit their own failings, and will lie through gritted teeth in denial. Embassies and consular services need to be very vocal about the dangers of travelling to Thailand. Thailand doesn't need to hand them out - our own countries could put this advise in their travel advisory, but who really reads those ??... So, any warnings or advisories are likely to go unnoticed. If Embassies start getting very vocal, they will damage ties they have built and a major part of their mission is to develop ties with Thailand. That said - this is a 'pretty damn important issue for Thailand to address' [road safety] - but as you mentioned, getting those in positions of authority and power to admit failings is a pretty tough sell. A cultural shift is required, and perhaps thats part of the issue, for the safety culture in many Western nations results in people becoming desensitised and somewhat ignorant to the risks overseas - perhaps thats something we should take care of with the education in our home countries now that the world is so much smaller and the vast majority of folk will travel overseas - educate people that elsewhere its different. -

The Struggle for Supremacy: Can Trump Halt China’s Global Ascent?
In 10-15 years China is world dominant.. USA, Russia, Europe will be a distant 2nd. China will have invaded Taiwan, will have naval bases in many Asian countries, and be propping up many African governments with money and business. The Belt and Road plan will reach to Europe with tentacles to Africa and the whole of the Pacific. Could go on, but that's the drift of the future. -

Palestinian Columbia Protester Detained by ICE During Citizenship Appointment
Because hes having having his educational visa revoked by the Government and h will have to leave the USA . A few months ago the pro Palestinians were running riot , causing a disruption and trying to influence USA politics . Foreigner students paid for by Countries hostile to the USA trying to influence USA politics . They succeeded under Biden ., It all changed when Biden went and Trump came along . The Palestinians actually could have encouraged people to vote for Trump -

Sunscreen Required to Survive
Sunscreen helped Homo sapiens outlive Neanderthals, study suggests Neanderthals became extinct leaving modern humans as the sole-surviving hominin left on Earth. Cave dwelling, clothing and sunscreen may be the reason Homo sapiens outlasted the Neanderthals, a new study suggests. Neanderthals became extinct about 40,000 years ago, leaving modern humans as the sole-surviving hominin left on Earth. Now a new theory suggests that the replacement could have been down to how the two groups responded to an increase in harmful UV radiation from space, sparked by an unusual flipping of the magnetic poles. About 41,000 years ago, a temporary reversal of the poles occurred – known as the Laschamps excursion. It lasted about 1000 years and weakened Earth’s magnetic field to about 10% of its current strength. It may not be winter yet, but the winter bugs are going around Earth’s magnetic field protects the planet from harmful solar radiation and cosmic rays. Without it, populations can be dangerously exposed. Scientists from the University of Michigan modelled the regions that were most vulnerable during the period and found they tallied with human activity in Europe and Asia. Archaeological evidence shows that around the same time, Homo sapiens started making tailored clothes, dwelling in caves and using ochre as body paint – all of which would have screened them from the increased radiation. “Having protection against solar radiation (from clothing) would have conferred significant advantage to anyone who possessed it,” said Dr Raven Garvey, associate professor of anthropology at the University of Michigan. “There have been some experimental tests that show ochre has sunscreen-like properties. It’s a pretty effective sunscreen, and there are also ethnographic populations that have used it primarily for that purpose. “It’s increased production and its association primarily with anatomically modern humans during the Laschamps is also suggestive of people having used it for this purpose as well.” While clothing, ochre and cave dwelling could have protected Homo sapiens, there is little evidence that Neanderthals had the same practices. At sites associated with modern humans, archaeologists have found hide-scraping stones, as well as needles and awls, which were probably used for sewing, but these were absent from Neanderthal sites. Tailored clothing, as well as protecting from UV rays, also brought warmth, meaning people could travel farther from their hearths and shelters in search of food. Homo sapiens also probably stepped up their use of ochre, a naturally occurring pigment comprising iron oxide, clay and silica that has been used by many species to paint objects, cave walls and decorate their bodies “I think it’s important to note that these findings are correlational,” Garvey added. “But I think it is a fresh perspective on the data in light of the Laschamps excursion.” Earth’s magnetic field is created by the rotation of its molten iron core, which generates an electric field that forms around the globe. This magnetic field has a north and south orientation, the North and South poles, but occasionally these poles wander from their traditional geographic positions, known as excursions. The Laschamps excursion caused Earth’s magnetic poles to drop down near the Equator and would have caused aurora to be seen all over Europe and into northern Africa. It coincided with a big shift for humanity. “In the study, we combined all of the regions where the magnetic field would not have been connected, allowing cosmic radiation, or any kind of energetic particles from the sun, to seep all the way into the ground,” said Dr Agnit Mukhopadhyay, a climate, space sciences and engineering expert at the University of Michigan. ‘Prehistoric sunscreen’ “We found that many of those regions actually match pretty closely with early human activity from 41,000 years ago, specifically an increase in the use of caves and an increase in the use of prehistoric sunscreen.” Mukhopadhyay added: “If such an event were to happen today, we would see a complete blackout in several different sectors. “Our communication satellites would not work. Many of our telecommunication arrays, which are on the ground, would be severely affected by the smallest of space weather events, not to mention the human impacts, which would also play a pretty massive role in our day-to-day lives.” The study was published in the journal Science Advances. -

Why, Oh Why: has the Left turned on Elon? No more gravy-train?
I was an Elon fan because of space x and also his boring machine ideas since I have a background and education in mining. I changed my opinions on how he handled the twitter purchase. He acted like a rich brash child. Then my administration turned to full contempt when I reinstated trump's acct. But blocked the smart kid who tracked his planes miliage. He has made twitter his personal platform and has outdid Murdock in the disinformation. Then cake his election support for trump, his election bribery, his Nazi salute, his support for the Nazi party in Germany. I had been following the government scrutiny of his self driving cars and exploding starships and it's obvious why he paid trump 230 million. So he can get rid of government oversite. He chose the wrong method using optics rather than lidar but won't admit it. Only thing we have in common now.
