Dow Chemical Punished for Lying About the Safety of New Herbicide

Alex Pietrowski, StaffA potentially dangerous new product, Enlist Duo, from Dow Chemical might actually undergo the scrutiny it deserves, now that the U.S. Environmental Protection Agency (EPA) has asked the Ninth U.S. Circuit Court of Appeals to abandon its approval of the herbicide. New information that the EPA discovered in a review of Dow’s patent application for Enlist Duo – which Dow seems to have conveniently omitted in its application to gain the agency&rsquo [...]

The Story of Human Evolution Now Challenged



Story of Human Evolution Challenged


Excerpt from newhistorian.com

The history of the evolution of early humans has been challenged.
Until now, one of the most dominant theories about our evolution claimed that our genus, Homo, had evolved from smaller early humans becoming taller, heavier and longer-legged. This process eventually resulted in Homo erectus, which was able to migrate out of Africa and colonise Eurasia.

Whilst we know that small-bodied H. erectus, averaging less than five feet tall and weighing under 50 kilograms, were living in southern Europe by 1.77 million years ago, the origin of the larger body size associated with modern humans has been elusive.

The paucity of knowledge about the origins of larger members of the Homo genus is primarily a result of a lack of evidence. Previous estimates of body size had been based on well-preserved specimens which were easy to assign a species to. Since these samples are rare and disparate in terms of both space and time, little is known about geographical and chronological variation in the body sizes of the early Homo.

A joint study between the Universities of Cambridge and Tübingen has shown that increases in body size occurred thousands of years after H. erectus left Africa; this growth in Homo body sizes primarily took place in the Koobi Fora region in modern Kenya.

“The evolution of larger bodies and longer legs can thus no longer be assumed to be the main driving factor behind the earliest excursions of our genus to Eurasia,” said Manuel Will, co-author of the study which has been published in the Journal of Human Evolution.

By using tiny fragments of fossil, the team were able to estimate our earliest ancestors’ height and body mass. Their findings, rather surprisingly, indicate a huge diversity in body size; this is particularly surprising as the wide variation we see in humans today was thought to be a relatively recent development.

“If someone asked you ‘are modern humans 6 foot tall and 70kg?’ you’d say ‘well some are, but many people aren’t,’ and what we’re starting to show is that this diversification happened really early in human evolution,” said Dr Jay Stock, co-author of the study.

Stock and Will are the first scientists in 20 years to compare the body size of humans from between 2.5 and 1.5 million years ago. They are also the first to use fragmentary fossils – many as small as toes, none longer than 5cm – to estimate body sizes.

By comparing measurements of fossils from sites in Kenya, Tanzania, South Africa and Georgia, the researchers have revealed substantial regional variation in the size of early humans. Groups who lived in South African caves, for example, were 4.8 feet tall on average. Some of the skeletons found in Kenya’s Koobi Fora region would have stood nearly 6 feet tall, a height comparable to the average height of modern British males.
“Basically every textbook on human evolution gives the perspective that one lineage of humans evolved larger bodies before spreading beyond Africa. But the evidence for this story about our origins and the dispersal out of Africa just no longer really fits,” said Stock.

It appears that Stock and Will have rewritten the history of the development of early humans; diversity has deep roots amongst the Homo genus.

Scientists Slow Down The Speed Of Light in Lab

Excerpt from popsci.com


Light passes through air at about 299,000,000 meters per second, an accepted constant that hasn’t been challenged—until now. By manipulating a single particle of light as it passed through free space, researchers have found a way to slow down the speed of light through air.

Scientists have known for a while how fast light passes through different mediums, such as water or glass, and how to slow that speed down. But researchers at the University of Glasgow and Heriot-Watt University decided to take this concept further and see if the speed of light could be changed as it passes through gases.
To make that happen, the team decided to look at individual light particles, or photons. “Measuring with single photons is the cleanest experiment you can get,” Jacquiline Romero, one of the study’s lead authors and a physics professor at the University of Glasgow, tells Popular Science. The group wanted to explicitly establish that different photons have different velocities depending on their placement within a light beam's structure. Depending on where a photon is in a light beam, it has either a slower or faster relative speed. It's similar to a group of runners: Even as the group stays together, the one at the front has to constantly be moving faster than the ones at the side or in the back. Daniel Giovannini, another study lead author from the University of Glasgow, says that researchers have known this for a while, but the team wanted to know just how slow the photons in the 'back of the pack' are moving.

The experiment set out to measure the arrival times of single photons, Romero says. To do that, the researchers passed one photon through a filter, which changed the photon's structure. They then compared the velocity of this photon to an unstructured photon. The researchers were able to decrease the velocity of the structured photon through air by 0.001 percent, which seems quite small, but the amount was not accidental. “We had to try it out and convince ourselves that it can be done and that it’s real,” Giovannini says. He and Romero say they anticipate the results will be divisive, between people who think the conclusion is obvious and those who think it’s a groundbreaking experiment.

The study was published January 23 in Science Express.
