In Heart of Darkness, Jeremiah P. Ostriker and Simon Mitton add new stars to the constellation of astronomy to tell the subject's full history

WE HAVE all heard of the Hubble Space Telescope, named after Edwin Hubble, but where is the Tinsley telescope?

Beatrice Tinsley was an excellent astronomer, but her career was stymied by an establishment set against giving a salary to the wife of an academic - even if she was also a gifted scientist. Tinsley made at least two vital contributions to our understanding of the universe's history, but she had to divorce her husband and grant him custody of the children to get any recognition of her talents.

In Heart of Darkness, Jeremiah Ostriker and Simon Mitton explore modern cosmology while recasting what they term the "simple linear parade of heroes" of standard accounts. Among the uncelebrated stars of cosmology they discuss, Tinsley shines brightest, but there are others: Milton Humason, a poorly educated mule-driver and janitor who assisted Hubble in his observations, and Vesto Slipher, who, despite working in the shadow of a boss obsessed with finding evidence for Martian civilisations, made the first observations that told us about the expansion of the universe.

Why do some names last and others fade? As well as being a great astronomer, Hubble was a "showman", and a "comfortable celebrity", say Ostriker and Mitton. Tinsley, meanwhile, was diagnosed with cancer the year she finally made full professor (at Yale). She died four years later, aged 40. Like a supernova, she burned brightly but briefly. Hopefully, this thorough and inspiring book will secure her a place in cosmological history.

Not that Ostriker and Mitton's book is focused solely on people - quite the opposite. Relatively few biographical details are given: it is their scientific contributions that are explored - and with aplomb.

This is a strong, confident book, easily one of the best guides to why cosmologists make the claims they do. Yet for all their redistribution of credit, the cosmology that the authors set out remains uncontroversial. It is the universe that began in a singularity, passed through a period of rapid inflation, and is now dominated by dark matter and dark energy. The state of our knowledge, they say, represents a "stunning" accomplishment.

This is the dilemma of modern cosmology: what counts as success? Summing up, Ostriker and Mitton simultaneously cite a "pretty impressive list of successes" while acknowledging that cosmology is "profoundly incomplete". We don't know what caused the inflation, what constitutes dark matter or what lies behind dark energy. In the end, the authors settle for a declaration that there's plenty for future cosmologists to do.

If there is one flaw in this crystal clear book, it's a lack of depth in the discussion of the dark side of the universe. It provides the book's title and is supposed to account for 96 per cent of the universe, but is confined to two chapters towards the end. Alternatives to dark matter are dismissed in little more than a paragraph and compared to pre-Copernican efforts to keep the Earth at the centre of the cosmos. When many respected scientists support the continued search for alternatives, that seems somewhat disingenuous.

Were she still with us, Tinsley would no doubt argue that there are compelling reasons to believe in the existence of dark matter, but that there are good reasons to consider alternatives, too. Her unique contribution to cosmology was to persuade a dismissive establishment that galaxies change their properties over time. In so doing, she exposed a gaping hole in the cosmology of the 1970s. It was a supreme achievement, if unwelcome.

Clearly, if you want your name to go down in history (or onto a telescope) it's better to be a showman than a troublemaker. But if the history of science teaches us anything, it's that the troublemakers should be celebrated too.

Football: Centralised training for S'pore team for 2013 SEA Games

SINGAPORE: Members of the LionsXII and the Courts Young Lions will form the bulk of the Singapore football squad for the 2013 SEA Games in Myanmar.

Despite its regional powerhouse status, Singapore has never won a gold medal in football at the SEA Games competition and the Lions are gunning to end the barren run in Myanmar this year.

To achieve that, the Football Association of Singapore (FAS) is looking to bring the teams together for centralised training ahead of the Games.

It is critical that the Young Lions and LionsXII have more playing time together.

This will allow selectors enough time to get the SEA Games team to gel and make changes before the December tournament.

FAS president Zainudin Nordin said: "If we are able to pick a suitable month where both calendar can fit in, why not. We can have a team going on a training programme that will put them into a single fighting unit. I think we will work hard towards that."

A good result at the 2013 SEA Games will continue the momentum from the 2012 AFF Suzuki Cup win where the Singapore team clinched a historic fourth ASEAN football title.

On Monday afternoon, the Courts Young Lions received a boost when its sponsor, Courts, decided to stick with the team for another year with a sponsorship deal estimated to be in the region of S$500,000.

The support will keep the focus on the youngsters and allow them to prove themselves, especially with better quality star players signed by some teams.

Courts Young Lions coach Aide Iskandar said: "The objective of the Courts Young Lions this year is to provide a platform, to create a wider pool of players for the coach to bring the team and to select the team for the 2013 SEA Games."

Facebook's earnings: It's all about mobile

All eyes are again on Facebook as it prepares to report fourth-quarter earnings, a make-or-break event that will determine whether the social network can continue its remarkable recovery from a stock market coma induced by a disastrous initial public offering.

Facebook, Wall Street's one-time punching bag, went from zero to hero with its share price swelling more than 60 percent from $19 and change to more than $31 in the past three months. Even an investor-disappointing Graph Search announcement did little to sway the social network's upward momentum. Today, Facebook, while still below its IPO offer price of $38, looks surprisingly healthy at $31.54.

So what happens now? Wall Street's consensus is that the social network will report $1.52 billion in revenue and earnings per share of $0.15. Should Facebook miss or clobber the top line number, the stock will move, but more is at stake. Facebook needs to show that its milking more money from its growing mobile audience, that other cash-making strategies are truly working and, above all, keep the Street convinced that its business is on the right track.

Zero to hero in 90 days
Toward the end of October, Facebook looked like a dud. The social network's shares were trading at around half of its IPO price of $38. Investors and analysts had zero confidence in the company's ability to profit from users who were quickly shifting their attention from desktops to smartphones and
tablets. And there was fear that end-of-year lock-up expirations on those suddenly able to see pre-IPO shares would drive the stock price down further.

When Facebook reported its third-quarter earnings, however, the company proved to investors that it was serious about making money, particularly on mobile, where it now has 604 million monthly active users. Overall, mobile accounted for 14 percent of Facebook's advertising revenue, or roughly $152.6 million, in the third quarter. At the time, Facebook also said that it was making $3 million per day from so-called Sponsored Stories in the News Feed on mobile phones and tablets.

That mobile successes lessened the fear among investors that mobile was such a big risk for Facebook -- a fear that Wedbush analyst Michael Pachter says was overblown. "I've had a $35 target since July," he said. "I refuse to budge."

Ultimately, the fundamentals of the company have not changed in the past 90 days, Pachter said. Instead, fear around mobile subsided. CEO Mark Zuckerberg personally helped dose out the everything-is-A-OK meds when he stressed how strong Facebook was performing on mobile.

But what now?
Facebook is entering Wednesday's earnings report in a position of the strength.

The social network successfully mitigated sizable lock-up expirations in October, November, and December, which added 1.2 billion shares to the public pool. The company is also now in its seventh month of offering Sponsored Stories, or status updates from brands who pay to promote their stories in members' News Feed, which means it should be able to show dramatic revenue growth from the desktop- and mobile-friendly units. Facebook also pushed its Gifts products out to all U.S. members before the holiday, ramped up its efforts to allow developers to pitch people on their applications through mobile app install ads, and started charging to deliver messages to strangers.

Some of these products may each only contribute between $20 million to $100 million to Facebook's bottom line, Pachter said, but so long as Facebook shows that the percentage of advertising revenue derived is growing on mobile, investors will be pleased. Pachter predicts that Facebook will report 17 percent of advertising revenue from mobile products in the fourth quarter.

RBC Capital Markets identifies what it views as positive, negative, and neutral results for Facebook in the fourth quarter.

Of course, Wall Street wants to hear more about Graph Search. Analysts are particularly curious about the potential financial impact of the curated search tool, as detailed in RBC Capital Market's pre-release report on Facebook.

They also want to hear from Facebook about the Instagram privacy policy debacle and understand whether there has been a measured drop off in users or activity, and they want to be reassured that Facebook will keep its spending in check. Should Facebook not satisfy queries in these areas, the company could be in jeopardy of losing some of the ground its picked up in recent months.

"We continue to like Facebook shares and view the company as arguably the most under-levered name in the Internet sector," RBC concluded.

The firm identified positive, neutral, and negative results, as pictured above. Basically, Facebook will really bring home the bacon if it can surprise Wall Street with $1.54 billion in revenue, earnings per share greater than $0.15, more than $1.25 billion in ad revenue, and more than 640 million daily active users. Conversely, anything lower than $1.52 billion in total revenue and $0.14 earnings per share will be miss. RBC's financial estimates have Facebook sliding into position somewhere between the negative and neutral zones.

It's a far simpler equation for Pachter, who views the social network with rose-colored glasses.

"[Facebook] has done everything right," he said, "and they will continue to do everything right."

Doomed Dolphin Speaks to New York's Vibrant Wildlife

By the time New Yorkers spied a dolphin swimming through the superfund sludge of the Gowanus Canal last Friday, it was too late. The marine mammal didn't even survive long enough for a rescue plan to come together. First sighted on Friday afternoon, the dolphin perished at 6:00 p.m.

The reason the marine mammal died, and why the dolphin swam up the polluted waterway in the first place, is as yet unknown. But the sad story of the wayward creature highlights the strange nature of New York City, the global epitome of urbanity. Hidden within Gotham are native carnivores, marine mammals, and even species that have scarcely been seen before.

Marine mammals are arguably the most high-profile of New York City's wild residents and visitors. The Gowanus Canal dolphin was only the latest to venture within city limits. Just a month ago, a 60-foot-long finback whale (Balaenoptera physalus) became stranded in the Rockaway Inlet of Queens. The emaciated animal died the day after it was discovered.

There seems to be no singular reason explaining why marine mammals such as the Gowanus dolphin and Queens' finback whale wander up the city's rivers or strand on beaches. Each case is unique. But not all the city's marine mammal visitors suffer terrible fates.

In 2006, a hefty manatee (Trichechus spp.) took a long jaunt from its Florida home up the East Coast, including a detour down New York's Hudson River. The sirenian survived the trip, continuing on to Cape Cod before reportedly turning back south to a destination unknown. Hopefully the manatee didn't encounter any great white sharks (Carcharodon carcharias) on the return journey, a marine predator we know patrols the waters off New York.

Of course, New York City's whales, seals, and occasional manatee can only skirt the city along its shores and canals. You likely won't see a seal caterpillaring its way along Broadway.

Yet the city's interior also hosts a strange accumulation of wildlife, including native animals that are carving out spaces for themselves in the concrete corridors and exotic species that we have introduced to city life.

Coyotes (Canis latrans) may be the cleverest of New York City's hidden wildlife. Thanks to camera traps, and the occasional police chase through Lower Manhattan, researchers are keeping track of the wily canids and studying how they are so successfully taking up residence in many of the nation's cities. "Most small, urban parks will likely hold a pair and their offspring at most—coyotes are very territorial," said Cornell University ecologist Paul Curtis.

The secretive carnivorans bring a welcome element to urban neighborhoods—an appetite for rodents—and are experts at cracking open new niches alongside people.

Black bears (Ursus americanus) may be next. The bears have proliferated in northern New Jersey in recent years, and in 2010, a black bear came within three miles of the George Washington Bridge, a major thoroughfare between New Jersey and Manhattan. The bear obviously would have eschewed rush hour traffic and the tolls, but the local population is so bountiful that it's not unreasonable to think some enterprising bear might eventually wander into the big city.

Strangely, you may actually be more likely to run into a crocodylian predator in New York City than a black bear. New Yorkers have a nagging habit of importing—and losing-alligator—like caimans and other reptiles within the city.

In 2010, an 18-inch long caiman took refuge under a parked Datsun in Astoria, Queens. No one knows how the reptile wound up on the street, but given the trend of owners buying cute crocodylians and later dumping them, someone may have abandoned the poor little caiman.

This would hardly be the first time. In 2006, another little caiman was found in the leaf litter behind Brooklyn's Spring Creek Towers, while "Damon the Caiman" swam around a Central Park lake in the summer of 2001. These caimans are only some of the most famous—according to a New York Times report, the Brooklyn-based Animal Care and Control deals with about ten caimans each year.

Many other unusual and exotic animals have romped through New York. Under some of their most notable animal celebrities, the city's Parks and Recreation department lists guinea pigs, boa snakes, and even a tiger that escaped from a circus in 2004 and ran down Jackie Robinson Parkway before his owners were able to get him back.

The Big Apple even contains species that have never been documented before. No, not the ballyhooed "Montauk Monster"—actually a rotted raccoon—but a distinct species of leopard frog. Described early this year, the cryptic amphibian was given away by its unique mating call.

Victims' Cellphones Ring After Nightclub Fire

Coffins lined a gymnasium in Santa Maria, Brazil, today as family members tried to identify their loved ones after a fast-moving fire tore through a crowded nightclub Sunday morning, killing more than 230 people and injuring hundreds more.

A community gym near the popular Kiss nightclub has been converted to a temporary morgue were family members were led in one by one Sunday night and early this morning to identify the dead. Outside the gym police held up personal objects, including a black purse and blue high-heeled shoe, as people seeking information on loved ones crowded around, hoping not to recognize anything they were being shown.

"Doctors from other parts of Brazil were flown in to assist the medical side of this," BBC reporter Julia Carneiro told ABC News this morning. "One hundred people are injured and in hospital. Some have been flown to other cities that have better hospital capacity."

Flames and smoke outraced a terrified crowd at the Kiss nightclub, located in the southern city of Santa Maria, shortly after 2 a.m. Sunday morning. Panicked partygoers tried to outrun flames and black, thick smoke, but the club appeared to have only one open exit, police Maj. Cleberson Braida Bastianello told The Associated Press.

Police confirmed that the toll had risen to 233 with the death of a hospitalized victim.

Hours after the fire, cellphones on the victims were ringing inside the still-smoldering nightclub as family members tried to contact their loved ones, Brazilian radio reporter Sara Bodowsky told "World News" anchor David Muir.

Brazil Nightclub Fire: Nearly 200 People Killed Watch Video

"It's really like a war zone in here. We have 232 bodies laid down, side by side, so the families go inside one by one. They look at the bodies," Bodowsky said.

The first funerals for the victims were scheduled to begin later today for those families who have identified their loved ones.

"It was terrible inside. It was like one of those films of the Holocaust, bodies piled atop one another," police inspector Sandro Meinerz said Sunday. "We had to use trucks to remove them. It took about six hours to take the bodies away."

Investigators believe the blaze began when a band's small pyrotechnics show ignited foam sound insulating material on the ceiling, releasing a putrid haze that caused scores of people to choke to death.

Survivors and police inspector Marcelo Arigony said security guards briefly tried to block people from exiting the club in the mass confusion and chaos moments after the fire began.

But Arigony said the guards didn't appear to block fleeing patrons for long. "It was chaotic and it doesn't seem to have been done in bad faith because several security guards also died," he told the AP.

Police Maj. Bastianello told the AP by telephone the death toll was likely made worse because the nightclub appeared to have just one exit through which patrons could exit.

A security guard told the newspaper Diaro de Santa Maria that the club was filled to capacity, with 1,000 to 2,000 people inside.

Meanwhile, people outside tried to break through walls to get in to save those trapped inside.

Michele Pereira told the Folha de S. Paulo newspaper that she was near the stage when members of the band lit some sort of flare.

"The band that was onstage began to use flares and, suddenly, they stopped the show and pointed them upward," she said. "At that point, the ceiling caught fire. It was really weak, but in a matter of seconds it spread."

Guitarist Rodrigo Martins told Radio Gaucha that the band, Gurizada Fandangueira, started playing at 2:15 a.m. "and we had played around five songs when I looked up and noticed the roof was burning."

"It might have happened because of the Sputnik, the machine we use to create a luminous effect with sparks. It's harmless, we never had any trouble with it," he said. "When the fire started, a guard passed us a fire extinguisher, the singer tried to use it but it wasn't working."

He confirmed that accordion player Danilo Jacques, 28, died, while the five other members made it out safely.

Brazilian President Dilma Rousseff, who was attending a summit with European Union leaders and the Community of Latin American and Caribbean States in Chile, cut her trip short and returned home to Brazil Sunday.

Weird high-energy flare made by spitting black hole

GLOBS of plasma spat out by black holes can trigger the brightest flashes of light in the universe.

Gamma-ray bursts are high-energy flares that mostly originate billions of light years away, making it hard to see how they are created. In November 2011, NASA's Fermi satellite saw a gamma-ray burst coming from the galaxy 4C +71.07, which sits about 10.5 billion light years away. The galaxy was also being watched by the Very Long Baseline Array, a radio telescope network that can see small features at a distance.

The supermassive black hole at the galaxy's centre is feeding on surrounding matter, causing it to fire high-speed jets of particles. The radio array showed that, around the same time as the flare, the black hole spat out a knot of plasma that travelled up the jet at near the speed of light.

Electrons in the knot probably collided with and energised light from a slower-moving part of the jet, producing the gamma rays, says Alan Marscher of Boston University, who presented the work at a recent astronomy meeting in California. It's still a mystery, though, what made the black hole erupt.

150 dead in Brazil nightclub fire: media

RIO DE JANEIRO: 150 people died early Sunday in a fire that broke out at a nightclub in the southern Brazilian city of Santa Maria, local media reported.

Santa Maria fire chief Guido de Melo said there was panic after the fire started and many revellers got trampled.

According to media reports, the fire erupted after 2:00 am (0400 GMT) when the nightclub hosted a university party featuring a rock band.

The band used pyrotechnics as part of its show, O Globo newspaper reported on its site.

"We have just taken the fire under control," Colonel Silvia Fuchs of the local fire department was quoted by the G1 website as saying. "Now we are removing the bodies."

Family member are gathering outside of the burned-down building in the hope of getting news of their loved ones.

The ultimate gall of a heartless iPhone thief

An object of desire?

(Credit:
CNET)

One should never expect justice in life.

The best one can hope for is poetry.

And yet, just once or twice, both manage to collide with a deliciousness that moves the soul.

Here is the tale of a teenage girl who had her iPhone stolen.

As The New York Times composes it, the girl had her
iPhone 4S ripped from her by a teenage boy in Brooklyn's notoriously difficult Prospect Park.

iPhone theft is rather popular in New York. Indeed, Mayor Bloomberg recently suggested that it's responsible for an increase in crime in the city.

Anyway, the iPhone-less girl collared a couple of policemen, but the miscreant was not to be found.

However, the thief then decided that he'd try to get some money for the phone. So he met a man on a Flatbush street -- as you do.

The man asked to take a look at the phone. Perhaps he wanted to see whether Siri was still inside.

Then, he ran off with it.

Yes, this is slightly poetic. But we've only just begun.

You see, the boy thief was not very happy. After all, he'd had his recently acquired property stolen. So he went off in search of a policeman to report the crime.

I pause for your sound effects.

Thank you.

More Technically Incorrect

The police reacted with unusual efficiency. They corralled both the boy and the man who had taken Siri from him. But they still assumed the boy was the victim.

Are you ready for verse three?

The phone rang. It was the girl trying to do a deal to get her phone back. The police realized something might be amiss here. This seemed to be a miss who actually owned the phone.

So they waited for her to arrive in Flatbush. She recognized the boy's sneakers. They were pink.

I pause for your further sound effects.

The police decided it was time to play Solomon. They would slice the phone in two if one party didn't renounce their claim to the phone.

No, wait. They asked both the girl and the pink-sneakered boy to unlock the phone with the PIN code.

You're already there, aren't you? Both the actual thieves were brought to justice -- the actual kind. And the girl got her phone back.

There are several morals to this story.

One, don't steal iPhones if you're wearing pink sneakers.

Two, if someone does unto you as you have done unto someone else, take it onto the chin. It will help you understand the feelings of others.

Three, if you're the kind of New Yorker who thinks they can always get away with it, well, you can't. Not always.

Pictures: The Story Behind Sun Dogs, Penitent Ice, and More

Photograph by Art Wolfe, Getty Images

If you want the beauty of winter without having to brave the bone-chilling temperatures blasting much of the United States this week, snuggle into a soft blanket, grab a warm beverage, and curl up with some of these natural frozen wonders.

Nieve penitente, or penitent snow, are collections of spires that resemble robed monks—or penitents. They are flattened columns of snow wider at the base than at the tip and can range in height from 3 to 20 feet (1 to 6 meters). The picture above shows the phenomenon in central Chile. (See pictures of the patterns in snow and ice.)

Nieve penitente tend to form in shallow valleys where the snow is deep and the sun doesn't shine at too steep an angle, said Kenneth Libbrecht, a physicist at the California Institute of Technology in Pasadena who studies ice crystal formation.

As the snow melts, dirt gets mixed in with the runoff and collects in little pools here and there, he said. Since the dirt is darker in color than the surrounding snow, the dirty areas melt faster "and you end up digging these pits," explained Libbrecht.

"They tend to form at high altitude," he said. But other than that, no one really knows the exact conditions that are needed to form penitent snow.

"They're fairly strong," Libbrecht said. "People have found [the spires] difficult to hike through."

Obama: Gun-Control Advocates Have to Listen More

President Barack Obama says gun-control advocates have to do a little more listening than they do sometimes in the debate over firearms in America.

In an interview with The New Republic, Obama says he has "a profound respect" for the tradition of hunting that dates back for generations.

"And I think those who dismiss that out of hand make a big mistake. Part of being able to move this forward is understanding the reality of guns in urban areas are very different from the realities of guns in rural areas," he says.

Gun Owners Rally State Capitals Across Country Watch Video

Andrew Cuomo Signs New York Gun Control Law, Obama Readies Federal Plan Watch Video

Obama has called for a ban on military-style assault weapons and high-capacity ammunition magazines and is pushing other policies following the mass shooting last month at an elementary school in Newtown, Conn. In response, gun-rights advocates have accused Obama and others of ignoring the Second Amendment rights of Americans.

The president says it's understandable that people are protective of their family traditions when it comes to hunting.

"So it's trying to bridge those gaps that I think is going to be part of the biggest task over the next several months. And that means that advocates of gun control have to do a little more listening than they do sometimes," he says.

Has Obama himself ever fired a gun?

"Yes," the president says, "in fact, up at Camp David, we do skeet shooting all the time."

His daughters don't shoot skeet at the presidential retreat in Maryland, he adds, "but oftentimes guests of mine go up there."

The interview appears in the Feb. 11 issue of The New Republic.
