The diamond planet

The universe is just full of wonders, and here is another one:

Astronomers have spotted an exotic planet that seems to be made of diamond racing around a tiny star in our galactic backyard.

The new planet is far denser than any other known so far and consists largely of carbon. Because it is so dense, scientists calculate the carbon must be crystalline, so a large part of this strange world will effectively be diamond.

“The evolutionary history and amazing density of the planet all suggest it is comprised of carbon — i.e. a massive diamond orbiting a neutron star every two hours in an orbit so tight it would fit inside our own Sun,” said Matthew Bailes of Swinburne University of Technology in Melbourne.

Lying 4,000 light years away, or around an eighth of the way toward the center of the Milky Way from the Earth, the planet is probably the remnant of a once-massive star that has lost its outer layers to the so-called pulsar star it orbits.

Human experimentation

Around the time Nazi doctor Josef Mengele was conducting his brutal medical experiments on human beings, some American scientists were doing pretty much the same thing:

U.S. government researchers who purposely infected unwitting subjects with sexually transmitted diseases in Guatemala in the 1940s had obtained consent a few years earlier before conducting similar experiments in Indiana, investigators reported Monday. . . .

At least 5,500 prisoners, mental patients, soldiers and children were drafted into the experiments, including at least 1,300 who were exposed to the sexually transmitted diseases syphilis, gonorrhea and chancroid, the commission reported. At least 83 subjects died, although the commission could not determine how many of the deaths were directly caused by the experiments, they said. . . .

In one case described during Monday’s two-hour hearing, a woman who was infected with syphilis was clearly dying from the disease. Instead of treating her, the researchers poured gonorrhea-infected pus into her eyes and other orifices and infected her again with syphilis. She died six months later.

The ultimate goal of the Guatemalan research was to determine whether taking penicillin after sex would protect against syphilis, gonorrhea and chancroid. The question was a medical priority at the time, especially in the military. The Guatemalan experiments, carried out between 1946 and 1948, aimed to find a reliable way of infecting subjects for future studies.

The research included infecting prisoners by bringing them prostitutes who were either already carrying the diseases or were purposely infected by the researchers. Doctors also poured bacteria onto wounds they had opened with needles on prisoners’ penises, faces and arms. In some cases, infectious material was injected into their spines, the commission reported.

The researchers conducted similar experiments on soldiers in an army barracks and on men and women in the National Mental Health Hospital. The researchers took blood samples from children at the National Orphanage, although they did not purposely infect them.

In the studies conducted in Indiana, researchers exposed 241 inmates in Terre Haute to gonorrhea in 1943 and 1944. But there, the researchers explained the experiments in advance in detail and experimented only on the prisoners who volunteered. In contrast, many of the same researchers who began experimenting on Guatemalans a few years later actively hid what they were doing and never tried to obtain permission, the commission found. . . .

Susan M. Reverby, a historian at Wellesley College in Massachusetts, discovered the Guatemalan experiments while doing research for a book on the infamous Tuskegee studies in Alabama. Reverby found papers from John C. Cutler, a doctor with the federal government’s Public Health Service. Cutler had participated in the Tuskegee experiment, in which hundreds of African American men with late-stage syphilis were left untreated to study the disease between 1932 and 1972. Cutler died in 2003.

How did the animals know?

Shortly before the earthquake hit Washington, D.C., the animals in the National Zoo started freaking out.   So did lots of people’s housepets, with sleepy cats suddenly jumping up and heading for the hills just prior to the quake.  Scientists can’t figure out how they knew:

Orangutans, gorillas, flamingos and red-ruffed lemurs acted strangely before humans detected the historic magnitude-5.8 earthquake. Now the question hovering over the zoo is: What did the animals know, and when did they know it?

Therein lies a scientific mystery, one in which hard facts and solid observations are entangled with lore and legend. There has been talk over the years about mysterious electromagnetic fields generated by rupturing faults. There has been speculation about sounds inaudible to humans, and subtle tilting in rock formations, and the release of vapors that people can’t smell.But there also may be less to the mystery than meets the eye, with Tuesday’s zoo weirdness merely serving as a reminder that many wild animals are paying close attention to nature while humans are doing whatever it is that humans do.

The zoo documented a broad range of animal behavior before, during and after the tremor that began in central Virginia and shook much of the eastern United States. For example, a gorilla, Mandara, shrieked and grabbed her baby, Kibibi, racing to the top of a climbing structure just seconds before the ground began to shake dramatically. Two other apes — an orangutan, Kyle, and a gorilla, Kojo — already had dropped their food and skedaddled to higher turf.

The 64 flamingos seemed to sense the tumult a number of seconds in advance as well, clustering together in a nervous huddle before the quake hit. One of the zoo’s elephants made a low-pitched noise as if to communicate with two other elephants.

And red-ruffed lemurs emitted an alarm cry a full 15 minutes before the temblor, the zoo said.

During the quake, the zoo grounds were filled with howls and cries. The snakes, normally inert in the middle of the day, writhed and slithered. Beavers stood on their hind legs and then jumped into a pond. Murphy the Komodo dragon ran for cover. Lions resting outside suddenly stood up and stared at their building as the walls shook.

Damai, a Sumatran tiger, leaped as if startled but quickly settled down. Some animals remained agitated for the rest of the day, wouldn’t eat and didn’t go to sleep on their usual schedule. . . .

The belief that strange animal behavior is a precursor to earthquakes goes back to antiquity. A recent scientific study suggested that toads fled to higher ground days before the 2009 earthquake in L’Aquila, Italy. In the most famous case of modern times, snakes and frogs emerged from their holes in 1975 in the dead of winter several weeks before a magnitude-7.3 earthquake in Haicheng, China (the odd animal behavior helped persuade officials to evacuate the city just before the tremor).

via Zoo mystery: How did apes and birds know quake was coming? – The Washington Post.

One explanation has to do with the so-called p-wave, a faint foreshock that precedes the big s-wave in an earthquake.  This is imperceptible to human beings, but maybe animals can pick it up.  The p-wave hit 15 seconds before the big 5.8-on-the-Richter-scale shock.  That would explain some of the animal behavior.  But some of the zoo animals started panicking a full 15 minutes before the quake.

America’s last space ship?

Last Thursday, July 21, the Space Shuttle Atlantis landed, ending the United States’ Space Shuttle program. And it may mark the end of manned flight, at least as far as the United States is concerned. Russia will still be able to send people into orbit, and American astronauts can hitch a ride with them to get to the International Space Station, another program whose days are numbered.  But there are no plans to update manned spacecraft  or start any more manned space programs.  See Shuttle Atlantis Final Landing Completes U.S. Retreat from Manned Spaceflight – IT Infrastructure – News & Reviews – eWeek.com.

So does this mean all of those science fiction fantasies about space being the final frontier and all that were just a blip of technological and imaginative optimism?

Pushing back against “born this way”

Postmodernists are opposed to “essentialism,” the notion that ANYTHING is innate or predetermined.  Thus I have found it interesting that when it comes to homosexuality, the prevailing argument is that this condition IS innate and predetermined.   I have been waiting for signs that postmodernism is on its way out, and this seemed to be a significant development.  But now it seems that postmodernists are pushing back against Lady Gaga’s assertion that we can all say “I was born this way.”  Instead we are seeing a revival of the notion that identity, including sexual identity, is “fluid.”  Thanks to Tim Challies for his comment alerting me to this from Gender Studies professor Suzanna Danuta Walters:

If marriage and military access are conjured as the Oz of queer liberation, then biological and genetic arguments are the yellow brick road, providing the route and the rationale for civil rights. The medicalization of sexual identity – and the search for a cause if not a cure – has a long and infamous history. This history includes well-meaning attempts by social activists to create a safe life for same-sex desire through the designation of homosexuality as biologically predetermined but also, more ominously, includes the sordid history of incarceration, medication, electroshock “therapy” and numerous other attempts to rid the body (and mind) of its desires.

Notions of homosexuality as “inbred,” innate and immutable were endorsed by a wide variety of thinkers and activists, including progressive reformers such as Havelock Ellis and not so progressive conservatives, eager to assert same-sex love as nature’s mistake. Richard von Krafft-Ebing in the 1880s and Magnus Hirschfeld in the 1903s – both pioneer sexologists and generally advocates of “toleration”– came to believe in some notion of “innate” homosexuality, whether through theories of a kind of brain inversion or through vague references to hormonal imbalances. These theories mostly had little traction, and no evidence whatsoever, and were further undermined during the heyday of the early gay movement which included a deep commitment to the depathologization and demedicalization of homosexuality, manifested in a long-term attempt to remove “homosexuality” as a disease category in the DSM.

Theories of biological origins of “gayness” have ebbed and flowed during different historical and social moments, most obviously intersecting with the rise of eugenics and other determinist frameworks in the early part of the last century. There is no question that the romance with biological and/or genetic explanations for sexual “orientation” has ratcheted up in recent years, due in no small part to the combined force of the gay marriage debates and the increasing “medicalization” and “geneticization” of behavior and identity, spurred on by the initiation of the human genome project in 1989 which furthered the already booming interest in genetic bases for behavior, personality, disease, etc. . . .

In our present political context, gay volition is like Voldemort – dangerous even to be uttered. This “born with it” ideology encompasses gay marriage, gay genes, gayness as “trait” and is used by both gay rights activists and anti-gay activists to make arguments for equality (or against it). This is bad science (mistaking the possibility of biological factors with wholesale causation) and bad politics (hinging rights on immutability and etiology). Causality is – of course – the wrong question and will only get muddled answers. The framing of “gayness” as an issue of nature vs. nurture or destiny vs. choice misses the point about (fluid, chaotic) sexuality and about civil rights. It’s not our genes that matter here, but rather our ethics.

Of course, the author doesn’t cite any evidence for her contention, just surveying the overall history of the question, which is how postmodernists tend to argue.

Pollution cures global warming

Climate scientists–the established ones, not the renegades–have found that global surface temperatures did not rise from 1998 to 2008, despite heightened carbon emissions, and they have been trying to figure out why.  Now they are saying the temperature drop is anthropogenic, the result (like they had been saying of global warming) of pollution, just a different kind:

Smoke belching from Asia’s rapidly growing economies is largely responsible for a halt in global warming in the decade after 1998 because of sulphur’s cooling effect, even though greenhouse gas emissions soared, a U.S. study said on Monday.

The paper raised the prospect of more rapid, pent-up climate change when emerging economies eventually crack down on pollution.

World temperatures did not rise from 1998 to 2008, while manmade emissions of carbon dioxide from burning fossil fuel grew by nearly a third, various data show.

The researchers from Boston and Harvard Universities and Finland’s University of Turku said pollution, and specifically sulphur emissions, from coal-fueled growth in Asia was responsible for the cooling effect.

Sulphur allows water drops or aerosols to form, creating hazy clouds which reflect sunlight back into space.

“Anthropogenic activities that warm and cool the planet largely cancel after 1998, which allows natural variables to play a more significant role,” the paper said.

Natural cooling effects included a declining solar cycle after 2002, meaning the sun’s output fell.

The study said that the halt in warming had fueled doubts about anthropogenic climate change, where scientists say manmade greenhouse gas emissions are heating the Earth.

“It has been unclear why global surface temperatures did not rise between 1998 and 2008,” said the study published in the Proceedings of the National Academy of Sciences of the United States.

Good thing it exactly balanced out!  Otherwise we’d be causing a new ice age that would also destroy civilization as we know it.
