Supernova theory explains global warming, extinction events, ice ages says engineer

Do Supernova Events Cause Extreme Climate Changes?

In recent years, mass die-offs of large animals - like the sudden deaths of 211,000 endangered antelopes within a matter of weeks - have been described as "mysterious" and remain largely unexplained.

Determining the cause of the retreat to ice ages and the abrupt warmings that spawned the interglacial periods has remained controversial for many decades.

Dr. William Sokeland, a heat transfer expert and thermal engineer from the University of Florida, has published a paper in the Journal of Earth Science and Engineering that proposes rapid ice melt events and ice age terminations, extreme weather events leading to mass die-offs, and even modern global warming can be traced to (or at least correlate well with) supernova impact events.

The perspectives and conclusions of researchers who claim to have found strong correlations that could explain such wide-ranging geological phenomena as the causes of glacials/interglacials, modern temperatures, and mysterious large animal die-offs should at least be considered...while maintaining a healthy level of skepticism, of course.

Discovery - if that is potentially what is occurring here - is worth a look.

A new species that has been dubbed a hidden 'monster' of the plankton world has been found lurking under Arctic sea ice in Canada.

The fortuitous discovery of the eight-legged creature - which freakishly only has one eye, no mouth and two hairy antennae - was made by a University of Manitoba student in 2014.

Aurelie Delaforge was working at an ice camp in the wilds of Cambridge Bay, Nunavut, to study plankton blooms when the zooplankton emerged in ocean ice samples. With the bizarre creature turning up in ice on a number of occasions, Delaforge thought it likely that the species was local to the area.

Delaforge sent a message to Department of Fisheries and Oceans researcher Wojciech Walkusz, informing him: "I have this alien."

NEAR MISS: An asteroid is hurtling towards Earth tonight after a string of near misses
The newly-discovered space rock - named Asteroid 2017 TD6 - is expected to zoom past our planet at around 7.53pm.

It will be travelling at a distance of 191,000km away from civilisation.

According to NASA the chunk of rock is a whopping 22m wide.

Last week another asteroid made a close shave with Earth, as it soared past at a distance of just 27,000 miles above the surface.

Brain

Aid memory & attention with specific brain training

New research suggests a specific method of brain-training is significantly better in improving memory and attention than other training protocols. Johns Hopkins University researchers discovered the method that helps the most also demonstrates more significant changes in brain activity.

Researchers explain that while the brain exercise didn't make anyone smarter, it greatly improved skills people need to excel at school and at work. Investigators believe these results suggest it's possible to train the brain like other body parts - with targeted workouts.

The study appears in the Journal of Cognitive Enhancement.

Can geoengineering protect corals from the warming climate?
Time for artificial planet coolers? A cooling "sunshade" for the planet could reduce harmful coral bleaching and the number of hurricanes, which damage reefs.

With the effects of climate change becoming increasingly apparent, the idea of squirting a cloud of sulphate aerosols into the upper atmosphere is being investigated by several groups of scientists. This would scatter some of the sun's rays back into space, reducing the rate at which the Earth is warming.

Now a study by James Crabbe at the University of Bedfordshire, UK, and his colleagues examines what this form of geoengineering would do to the Caribbean region and its fragile reefs. "Corals are the rainforests of the sea, and if you lose them the impacts on ecosystems and people would be complex and far-reaching," says Crabbe.

The team used computer models to simulate both the changing climate and rising seas between 2020 and 2069. They then modelled what would happen if solar radiation was artificially reduced. "We show very convincingly that, by injecting sulphur dioxide in the atmosphere, sea surface temperatures would decrease significantly by 2069," says Crabbe.

Hold back the hurricanes

When the sea is too warm, corals expel the tiny algae living in their tissues, which feed their hosts through photosynthesis. The corals turn white or "bleached". After severe bleaching, most corals starve to death. Keeping temperatures down prevented this in the model.

9.7mn-yo ape teeth discovered in Germany puzzle scientists, challenge timeline of human species

Ancient ape teeth dating back more than 9 million years and discovered in Germany last year are raising questions about the timeline of human evolution.

The two teeth, discovered in sediment of the Proto-Rhine River, are of an ape species whose remains have never before been observed in Europe.

Understood to belong to one ape, the two teeth are similar in structure to 3 million year old fragments belonging to an ape skeleton previously uncovered in Africa.

However, the German river bed remains, an upper right molar and left canine, predate the African example by more than 6 million years, according to a study published by the National History Museum Mainz.

Google's DeepMind group unveils AI that learns on its own

Match 3 of AlphaGo vs Lee Sedol in March 2016.
Google's artificial intelligence group, DeepMind, has unveiled the latest incarnation of its Go-playing program, AlphaGo - an AI so powerful that it derived thousands of years of human knowledge of the game before inventing better moves of its own, all in the space of three days.

Named AlphaGo Zero, the AI program has been hailed as a major advance because it mastered the ancient Chinese board game from scratch, and with no human help beyond being told the rules. In games against the 2015 version, which famously beat Lee Sedol, the South Korean grandmaster, in the following year, AlphaGo Zero won 100 to 0.

The feat marks a milestone on the road to general-purpose AIs that can do more than thrash humans at board games. Because AlphaGo Zero learns on its own from a blank slate, its talents can now be turned to a host of real-world problems.

At DeepMind, which is based in London, AlphaGo Zero is working out how proteins fold, a massive scientific challenge that could give drug discovery a sorely needed shot in the arm.

African gene study shows human skin tone has varied for 900,000 years

Researcher in the field measures skin colour
Skin tone has varied greatly among humans for at least the last 900,000 years. So concludes an analysis of the genetic variants associated with skin pigmentation in people from several regions of Africa. The latest findings suggest that some particularly dark skin tones evolved relatively recently from paler genetic variants, underlining how deeply flawed the racist concept of people with whiter skin being "more advanced" really is.

Nicholas Crawford and Sarah Tishkoff at the University of Pennsylvania in Philadelphia recruited around 1500 ethnically and genetically diverse volunteers living in Ethiopia, Tanzania and Botswana for their study. Each person agreed to provide a DNA sample and have their skin pigmentation measured (pictured above).

The combined data allowed the team to find eight sites in the human genome that are particularly associated with the level of skin pigmentation. Together, these sites account for about 30 per cent of the variation they found in skin pigmentation among the volunteers.

For each of the eight sites of variation, there existed a genetic variant associated with paler skin, and a variant linked to darker skin. Seven of the paler skin variants emerged at least 270,000 years ago. Four of these arose more than 900,000 years ago.

Recent study suggests drought and cold climate prompted ancient humans' move out of Africa

Ancient humans may have trekked out of Africa to escape arid climes. This is the result suggested by a record of climate in East Africa spanning the past 200,000 years.

"It raises the possibility that drought, rather than rainy conditions, prompted early humans to migrate," says lead author Jessica Tierney at the University of Arizona.

Modern humans are widely agreed to have evolved in Africa and are thought to have migrated out 65,000 to 55,000 years ago. They may have left via East Africa and headed to Arabia, although this isn't settled.

Previous studies showed that many parts of Africa, like the Sahara, have had many wet and dry periods. A marine core, collected from the Gulf of Aden off Africa's east coast in 1965, has sediments dating to 200,000 years ago. Analysing this allowed Tierney and her colleagues to construct an extended timeline of climate shifts in north-east Africa.

Chalkboard

It's time to fix the fact that most scientific papers end up drawing wrong conclusions

Crisis? What crisis?
Research findings often crumble under the microscope. Rows over the best way to fix this must end so we can stop trust in science crumbling too

In these times of fake news, it's good to know that there's still one source we can rely on: the scientific community. Wielding rigorous standards of evidence, researchers can be counted on to give us trustworthy insights amid a sea of nonsense.

Yet this, too, is fake news. For decades, scientists have been using flawed methods for turning raw data into insight about, say, the effectiveness of a new medical therapy or method of teaching. As a result, the research literature is awash with findings that are nothing more than meaningless flukes. No less shocking is the fact that researchers have been repeatedly warned about the problem, to no effect.

This week, the American Statistical Association (ASA) hopes to change that. It is hosting a conference intended to get the scientific community to mend its ways. But what has this scientific crisis got to do with statistics?
