A homosexual penguin couple from New York’s Central Park Zoo are back in the news now that a book about their relationship has been banned in Singapore. Keith Wagstaff looks at the core question about homosexual behavior in animals.
An early ancestor of the elephant and an early ancestor of modern humans lived together in North America. That was good news for the hungry people, but not for the proto-elephants
There were a lot of things on the menu for early Americans—deer, antelope, buffalo. But if you really wanted to eat well, and you were an especially early early American, there was nothing quite like a good haunch of gomphothere. That, it turns out, may have been one of the staples of the prehistoric Clovis culture, and while plenty of people never heard of this particular predator or its prey, the fact that they crossed paths is very big news.
The Clovis people are believed to be the earliest occupants of North America, arriving in the southwestern part of the continent somewhere between 13,000 and 13,500 years ago. Gomphotheres, a faintly freakish, four-tusked ancestor of the elephant, had the humans beat by a lot, first appearing on the scene as far back as 33 million years ago. The scientific wisdom had always been that the two species never co-existed, but the scientific wisdom hadn’t reckoned with a site called El Fin del Mundo (the end of the world) in northwestern Mexico.
Researchers from the University of Arizona, the National Autonomous University of Mexico and elsewhere began exploring the site in 2007, after a local rancher reported finding animal remains. They continued digging until 2012, and in a paper just published in Proceedings of the National Academy of Sciences (PNAS), revealed conclusive proof that the gomphotheres thundered and the Clovis people hunted at the same time and in the same place—and the Clovis got the better of the deal.
The first discoveries at the site were a few complete Clovis spear points, along with bones that appeared to be from a large bison. That made it a nice find, but hardly a remarkable one. The following year, however, the investigators unearthed a mandible that was not remotely bison-like, but was entirely gomphothere-like, and that changed everything.
Further digging revealed the complete remains of two gomphotheres—one 13 to 24 years old and the other a comparative juvenile at 10-12 years old. Mingled in with the bones were more spear points and though weathering on the bones made it hard to look for the cut marks and gouges that usually indicate butchering, the signs of a hunt were unmistakable. For one thing, animals that die natural deaths leave bones arranged in more or less the proper skeletal configuration. In this case, however, the remains were stacked in two distinct, non-anatomical piles.
The fact that some of the spear points the investigators unearthed were mingled in with the bones suggests that the Clovis hunters either simply tossed them there after they were done with the remains, or that the points were somehow lost in the flesh of the carcass and too hard to retrieve. The condition of the points suggests they may indeed have been well-embedded. “Three of the four points are complete,” the researchers wrote, “but the fourth is missing its base due to an impact-related snap.”
History was not kind to either the gomphothere or the Clovis culture. The proto-elephants eventually died off and were replaced by the modern, two-tusked model. And the Clovis culture eventually dispersed and settled into different sub-cultures, each adapting to the conditions on its own part of the continent. Some archaeologists think that the gomphothere might have had the last laugh, since the end of the Clovis line could have been caused by the disappearance of it and other such “megafauna” to hunt. The prey went down, but it may have taken the predator culture with it.
On the 45th anniversary of the moon landing, the U.S. should decide on the necessary steps to explore Mars with the eventual goal of establishing a manned settlement there.
It’s hard to believe that on July 20, 2014, we’ll be celebrating the 45th anniversary of Apollo 11, man’s first landing on the moon. It’s also hard to believe that no one can really say where the U.S. manned space exploration program is heading and how we’re going to get there. People come up to me and say, “It’s too bad the space program got canceled.” This is not the case, and yet that is what most of the public thinks has happened. Yes, we hear from NASA that the destination is Mars — and yet there is no detailed plan on how to get there. No one can seem to agree on a clear path. The nation is understandably focused on many other pressing challenges at the moment. However, if we don’t make some important decisions about the future of our space program very soon, I’m afraid the program will be lost to the ages.
There are eight U.S. astronauts left out of the 12 who walked on the moon. All of us are in the eighth decade of our lives. Each of us can attest to the importance of continuing human exploration of space and the tremendous impact it has had on so many facets of our society. The technical innovations, scientific achievements, medical breakthroughs, environmental enhancements, national defense improvements and educational impacts have been immeasurable. Our nation simply cannot afford to lose a program that has contributed so much for so long. Our leaders have some important decisions to make and they need to make them now. The moon must not be the last stop in America’s quest for knowledge of other planets and of other places.
Here’s what we as a nation must decide:
- Does the United States wish to continue leading human exploration of space or leave it to Russia, China, India or some other nation to take over? To me, the answer is obvious.
- Does it not make good sense for the U.S. to take the high ground by establishing cooperative U.S.-China relations in space? We did it with the Soviet Union through the Apollo-Soyuz program back in July 1975, and I believe it is even more important to do it with the PRC in 2014. Cooperation, not confrontation, should be the hallmark of our dealings with the Chinese beyond Earth.
- Does it make sense for the U.S. to expend hundreds of billions of dollars to mount a new Apollo-style program to return to the moon? Or have we blazed that trail? Shouldn’t we help other nations achieve this goal with their own resources but with our help? Rather than doing again something we did 45 years ago, shouldn’t the U.S. be developing a path toward Mars?
- And shouldn’t the U.S. develop the technological capabilities needed to land humans on Mars by first traveling to a nearby asteroid for research and development purposes? A hybrid human-robot mission to investigate an asteroid affords a realistic opportunity to demonstrate new technological capabilities for future deep-space travel and to test spacecraft for long-duration spaceflight. This is imperative, as we’ve never done manned missions beyond the moon.
- And speaking of Mars, are we prepared as a nation to take the necessary steps to explore Mars with the eventual goal of establishing a manned settlement on that planet? To me, the answer should be a resounding “yes.”
It’s unlikely that the remaining Apollo astronauts, including yours truly, will be around to witness the conclusion of the next exciting chapter in our nation’s space program. However, we would like to be here when our President and Congress make these critical decisions. If our leaders make the right decisions — and they must — we’re confident the new manned space program will meet or exceed the tremendous success of the Apollo program so many years ago. But let’s make these decisions now.
Dr. Buzz Aldrin served as lunar module pilot for Apollo 11, the first manned lunar landing mission. He is the author of eight books, including his New York Times best-selling autobiography Magnificent Desolation. His newest book, Mission to Mars: My Vision for Space Exploration, was published in 2013. As one of the leading space exploration advocates, Buzz continues to chart a course for future space travel.
The Guardian's dire report of a climate-change catastrophe unfolding in Miami is a case of premature evacuation
Help us! We’re drowning! It’s a catastrophe! DO SOMETHING!
Well, we’re not actually drowning. We do get damp every now and then, but it’s hard to see how some modest sunny-day flooding in my neighborhood at high tide justifies the Guardian headline that’s been generating so much buzz: “Miami, the great world city, is drowning while the powers that be look away.” I’ve described South Beach as the canary in America’s coal mine for climate change, and the canary has started coughing a bit, but it isn’t dead or even very sick. I’m sorry to spoil the climate porn, but while the periodic puddles in my Whole Foods parking lot are harbingers of a potentially catastrophic future, they are not currently catastrophic. They are annoying. And so is this kind of yellow climate journalism.
The Guardian article — by Robin McKie, the science editor (!) — begins a block from my home, on Alton Road, which is “hemmed in by bollards, road-closed signs, diggers, trucks, workmen, stacks of giant concrete cylinders and mounds of grey, foul-smelling earth.” That’s a pretty ominous description of a basic construction project. The state is rebuilding the street, in part (not entirely) because Biscayne Bay is backing up through storm drains at high tide, in part (not entirely) because global warming has helped increase the sea level around South Florida by about 10 in. over a century. McKie describes this gentle backwater flooding with absurdly apocalyptic prose: “Tidal surges are turned into walls of seawater that batter Miami Beach’s west coast and sweep into the resort’s storm drains.” He also claims that the water then “surges across the rest of the island,” which simply isn’t true.
“The effect is calamitous,” McKie writes. Calamitous!
“City life is paralyzed,” he continues. Paralyzed!
Well, it does get hard to park at Whole Foods. Puddles form in front of Walgreens. A few cars have been damaged — or, as McKie described it, “ruined” by “surging seawaters that corrode and rot their innards.” McKie was apparently too lazy to talk to any actual victims of our ongoing calamity, but he did rip off a quote from a laundromat owner who told the New York Times that Alton Road flooding once blocked the entrance to his front door. What’s happening in the Middle East right now is calamitous. A blocked entrance is inconvenient.
Hey, it’s been inconvenient for all of us. I’m bummed that my favorite Alton Road burger joint just closed, although its downfall was the construction mess, not the flooding. But let’s get real. The Pacific island of Kiribati is drowning; Miami Beach is not yet drowning, and the Guardian’s persistent adjective inflation (“calamitous,” “astonishing,” “devastating”) can’t change that. We should fight global warming — and the powers that be, including Senator Marco Rubio and Governor Rick Scott, should stop looking away — because it’s a potential disaster for Miami and the rest of this very nice planet. But we shouldn’t pretend it’s a disaster now.
I get why the Obama Administration wants to emphasize that global warming is a today issue, not a someday issue. I understand that stories about how climate change is already affecting our cities and our farms and our lives — even our wine — can make the issue feel more pressing to ordinary Americans. But fortunately, the effects are not yet calamitous; the reason we ought to DO SOMETHING is that they’ll get calamitous if we don’t. If we think once-a-month ankle-deep water is drowning, then why should Americans care whether we drown?
A new study makes it possible for you to hold one of astronomy's great mysteries in your hands—and understand it better too+ READ ARTICLE
People alive in 1841 understood the Eta Carinae nebula better than we do. They were the ones who were actually around to watch when an enormous star weighing about 130 times as much as our sun erupted more than 7,500 light years from Earth. Maybe if modern astronomers had been on the scene they could have figured out what caused the blast—and specifically why the vast cloud of dispersing matter that makes up the nebula assumed its signature peanut shape.
Still, the good thing about those modern astronomers is that when they put their minds to something, it’s never too late to get some answers. An international team of researchers has just announced that they have done just that, publishing a new study in the Monthly Notices of the Royal Astronomical Society that may at last unravel the Eta Carinae mystery.
The investigators did their work with the help of the European Southern Observatory’s Very Large Telescope (VLT), conducting elaborate cross-sectional observations of Eta Carinae. These allowed them not only to develop a solid theory about how the star blew, but to create a 3D-printed model of the two-lobed space cloud that came from it.
The model is not much to look at—two irregularly shaped balls of plastic that resemble extracted molars as much as anything else. Still, NASA has made the program necessary for printing your own version of Eta Carinae publicly available. Whether you think it’s display-worthy or not, the model tells a complex story.
The star at the center of the Eta Carinae nebula is actually two stars—a binary pair in perpetual orbit around each other. That had been known for a while, but how—or if—they worked together to shape the nebula was never clear. The international team now believes that the eruption occurred when the smaller star—which measures about 30 solar masses—was at the closest point in its orbit to the larger one. It does not appear that a collision triggered the explosion. That seems to have happened on its own, with the blast beginning at one of the poles of the 130-solar-mass star and propagating across its entire body to the other pole.
But the close approach of the smaller star does seem to have had a powerful influence on shaping the eruptive cloud that resulted—and that star had a lot of material to work with. The larger star, which still exists, is now thought to weigh in at just 90 solar masses; the missing material—about 40 times the mass of our sun—is what we see when we look at the huge cosmic peanut.
Why does any of this matter? Well, it doesn’t, if you take “matter” to mean influencing the well-being of the human species responsible for the finding. But if you mean making that species smarter, explaining to it how some of the universe’s most extraordinary and violently beautiful formations came to be, then it matters indeed—and quite a lot, in fact.
Germany’s decision to let midfield Christof Kramer keep playing in the World Cup final yesterday after being slammed in the head was understandable—if this were 1962, anyway. Back then, a little concussion wasn’t seen as much of a big deal.
That’s not true anymore, and given the fact that everyone from kids’ coaches to the NFL (if grudgingly) recognize that even mild head injuries can have serious consequences, that decision looks close to insane—especially given that Kramer “looked as if he was on another planet and had to be helped off the field,” as TIME’s Bill Saporito observed.
Of course, it’s possible that the German team didn’t realize that this sort of thing can cause permanent brain damage. Or maybe they think that what applies to American football is irrelevant to real football. Except that studies have shown that soccer players are equally at risk.
Clearly, they didn’t read the editorial in The Lancet Neurology published the day before the game reminding coaches and team officials that “cerebral concussion is the most common form of sports-related traumatic brain injury (TBI), and the long-term effects of repeated concussions may include dementia, amyotrophic lateral sclerosis, and other neurological disorders.” The decision to let players continue in a game, wrote these learned medical experts, should be made solely by doctors.
It turns out that FIFA doesn’t have any clear rules about what to do in case a player suffers an apparent concussion. But the fact that Kramer stayed in the game, no matter how important a World Cup final match might be, was at best highly questionable. “I can’t remember very much but it doesn’t matter now,” the dazed player reportedly said after the game was over.
If the medical professionals are right about how serious concussions can be, Kramer and his teammates might well have a different take on things a few years down the road.
New study reveals the greatest risks
The study published in the journal Pediatrics on Monday found that babies aged 0-3 months were most likely to die as a result of bed-sharing. For older infants ages four months to a year, the greatest risk for sleep-related death is objects in the sleep environment, the study found.
The study relied on a database compiled between 2004 and 2012—using information from 24 states—by the National Center for the Review and Prevention of Child Deaths. Researchers analyzed 8,207 deaths in total.
Of the younger victims, 74% were sharing a bed at the time of their death. The study defines “bed-sharing” as sleeping with a person or an animal. Of the older victims, 39% of deaths happened in a sleep area containing an object such as a blanket or a pillow. And 18% changed their sleeping position from on their side or on their back to prone.
But the study makes it clear that it hasn’t uncovered any clear cause and effect. Instead it states its “objective was to determine any associations between risk factors for sleep-related deaths at different ages.”
The American Academy of Pediatrics guidelines on safe sleep environments suggest placing babies on their back on a firm surface, in the same room as their parents, and with no soft objects or loose bedding until the age of one.
Astronaut Alexander Gerst tweeted this amazing picture of the above-earth view of a supermoon early Monday, when the moon was still behind the horizon.
Gerst is a German astronaut aboard the International Space Station and among many astronauts using the social media site to share incredible pictures of the view from space. Gerst often uses the hashtag #bluedot, a nod to the iconic image of Earth taken from Saturn. And earlier in July, NASA astronaut Reid Wiseman tweeted above-earth images of Super Typhoon Neoguri. Three astronauts recently spoke to TIME about life above the earth, read their comments in this week’s issue.
The biggest temblor clocked in at 4.3 on the Richter scale
Oklahoma was rocked by seven small earthquakes in a span of about 14 hours over the weekend, the U.S. Geological Survey said.
Three quakes hit between Saturday evening and Sunday morning, centered in the areas of Guthrie, Jones and Langston, and ranging between 2.6 and 2.9 in magnitude. They followed four larger temblors earlier on Saturday, including one near Langston shortly after noon that clocked in at 4.3 on the Richter scale.
