Stellar performances finally gain the limelight

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.

PM Lee admits govt lacked 20/20 foresight

SINGAPORE: Prime Minister Lee Hsien Loong has admitted the government did not have 20/20 foresight, resulting in problems with inadequate infrastructure in the country.

He was speaking at the "Singapore Perspectives" conference on governance organised by the Institute of Policy Studies on Monday.

Acknowledging the problems of insufficient housing and inefficient transportation network, Mr Lee pointed out that the government was blind-sided by the outcome of some international events.

He elaborated that in 2000 and 2001, the 9/11 terrorism attack on the United States plunged countries into recession. Singapore was dealt with a slow economy with minimum population growth and local housing prices went down.

But by 2005 and 2006, Mr Lee said the mood changed and the economy started picking up.

So, he said, the government did what it thought would have been appropriate then. It decided to make up for lost time by growing the population and boosting the economy.

He acknowledged that infrastructure like housing and transport didn't keep up with that growth.

He said: "We lacked that 20/20 foresight. Next time, we will try to do better, certainly to have a bigger buffer and not to cut things so fine."

Prime Minister Lee also dealt with sensitive issues that are brought up online.

Replying to a question on why there is a need to moderate social space, he said:
"We don't believe the community in the social space, especially online, moderates itself. It doesn't happen anywhere in the world.

"You have views going to extremes and when people respond to their views, they may respond in an extreme way, and when people decide to disapprove of something which was inappropriate, the disapproval can also happen in an extreme way.

"It's in the nature of the medium, the way the interactions work and that's the reason why we think it cannot be completely left by itself."

Brazil club fire: Pushing, shoving, then panic

STORY HIGHLIGHTS

• The owners of the nightclub pledged to cooperate with the investigation


• At least 231 people died in the fire, authorities say


• Funerals are scheduled to begin Monday for those killed in the fire

Santa Maria, Brazil (CNN) -- Guitarist Rodrigo Martins was preparing to launch into the sixth song of his band's set when he saw embers fall.

The acoustic foam insulation on the ceiling of the KISS nightclub in the southern Brazilian city of Santa Maria was on fire, and it was beginning to spread.

The hot ash fell onto the stage and dance floor.

In front of him, a sea of people who moments earlier were dancing and singing along to the country-pop sounds of his band Gurizada Fandangueira began to realize something was wrong.

Suddenly, concert-goers were stampeding toward the club's only exit, pushing and shoving each other trying to get out.

Then, according to investigators and witnesses, somebody fell in the narrow, dark hallway that led to the windowless exit.

And then another person fell.

And then another.

Searching for answers

It was the last weekend of Brazil's summer break for many of the students, and the KISS nightclub was packed early Sunday with young people, many of whom attended one of a number of universities and colleges in Santa Maria.

At least 231 people died and hundreds more were injured in the fire that authorities believe began about 2:30 a.m. Sunday when the band's pyrotechnic show ignited insulation material.

Many apparently died from smoke inhalation. Others were trampled in the rush for the exits.

Of the dead, 101 were students at the Federal University of Santa Maria.

Another 120 remained hospitalized Monday morning, 79 in critical condition, authorities said.

About 2,000 people were inside the club when the fire broke out -- double the maximum capacity of 1,000, said Guido de Melo, a state fire official.

The roof collapsed in several parts of the building, trapping many inside. Firefighters found piles of bodies in the club's bathroom.

It looked, said state lawmaker Valderci Oliveira, "like a war zone."

For others, escaping was complicated by the fact that guards initially stopped people from leaving, said a reporter from CNN affiliate Band News, echoing comments from the state fire official.

"Some guards thought at first that it was a fight, a huge fight that happened inside the club and closed the doors so that the people could not leave without paying their bills from the club," the reporter, Glauber Fernandes, said.

But Rodrigo Moura, a nightclub security guard, said the fire moved fast.

"All of a sudden the fire just took off and was all around us. We tried to tell people to get out," he said.

The owners of the nightclub, meanwhile, pledged to cooperate with the investigation into the fire, according to a statement released by the law firm of Kummel & Kummel.

"We are open to all authorities and inspections," said the statement, obtained by Globo TV.

The club's license had expired in August and had not been renewed, a local fire official told Globo TV.

The owners, however, said the nightclub was properly permitted and had been inspected by the fire marshal.

Deadly blazes: Nightclub tragedies in recent history

'Blocked by security'

The band, Gurizada Fandangueira, was a popular attraction at KISS in part because of its pyrotechnic show, according to Billboard.com. It played at the nightclub about once a month, and was there Sunday to promote a new album.

Martins, the guitarist, told Radio Gaucha the band had been on stage for about 20 minutes, finishing the fifth song of its set, when it set off its "sputnik" pyrotechnics -- sparkler columns that shoot up in the air.

"We used it all the time. ...We never had this problem before," he told the radio station late Sunday.

Martins said he first noticed a small ember, and then he looked up at the ceiling and saw the flames.

A backstage hand attempted to put out the blaze with a fire extinguisher. "But, it didn't work," he said.

Martins said as he and the other band members got off the stage, there were 20 to 30 people in front of him who were "being blocked by security."

People started pushing and shoving, and then they tripped over one another to the door.

Martins said the band's accordion player, 28-year-old Danilo Jacques, died in the fire. "I saw him, and then I lost him in the crowd."

Struggling to help

Esequiel Corte Real and his friends arrived late for the show and ended up with what they thought was one of the worst locations to watch -- by the exit.

The same happened with Norton Basson and his friends, who were at the club to celebrate his 29th birthday.

They are alive, they believe, because of where they were -- making them among the first to make it out alive.

After the fire started, the dark, narrow hallway that led to KISS nightclub's exit was choked with smoke and people trying to find their way out.

Outside, Corte Real and his friends could hear the screams of people trying to escape.

He told Globo TV that he and his friends ran back in to the club to try to help.

They pulled out one body. Then two more.

"Somebody must be alive," he said.

Basson and his friends, meanwhile, grabbed rocks, sticks and an axe they found at a nearby building and began trying to knock a hole in the side of the club to help those trapped inside. Others soon joined them with shovels and more axes.

Firefighters used the hole Basson and his friends created to get inside the club.

There, they were greeted by the eerie sounds of cell phones ringing in the pockets and purses of the dead. Many of the calls were from parents desperate to reach their children.

The missing

Later Sunday, family members wept as they searched for information outside a local gymnasium where bodies were taken for identification.

Inside, Brazilian President Dilma Rousseff met with relatives as they waited on bleachers for word of their loved ones. She had been attending a regional summit in Chile, but cut short the trip and returned to Brazil early to deal with the aftermath of the tragedy.

"The Brazilian people are the ones who need me today," she said. "I want to tell the people of Santa Maria in this time of sadness that we are all together."

Ericmar Avila Dos Santos went from hospital to hospital Sunday, searching for his 23-year-old brother.

Hours earlier, he learned in a telephone call from a friend that his older brother was among those missing following the fire.

His family scanned lists, talked with police officials. They checked with friends, searched everywhere.

They finally found him -- among hundreds of bodies laid out on body bags at a makeshift morgue at a local gym.

Rhode Island victims 'can't help but watch'

"I was supposed to go with him. I didn't feel like going out. He ended up there without me," Avila Dos Santos said, openly sobbing over his brother's coffin outside the gym.

On Monday, the first of Brazil's three days of mourning, the three cemeteries in the city of 260,000 were packed with families readying to bury their dead.

Among them: Avila Dos Santos' family.

"We did everything together. We were even studying the same major," he said, remembering his brother. "Now that he's gone, I'm lost. I don't know what I'm going to do with my life."

Gym Turned Into Morgue for Nightclub Fire Victims

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.

"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.

DNA privacy: don't flatter yourself

The secrets contained in our individual genomes are less valuable than we like to believe

IMAGINE donating your DNA to a project aimed at discovering links between genes and diseases. You consent to your genome sequence being released anonymously into the public domain, though you are warned there is a remote possibility that it might one day be possible to link it back to you.

A few years later, that remote possibility comes to pass. How should you feel? This is no longer a hypothetical scenario. About 50 people who participated in a project called 1000 Genomes have been traced (see "Matching names to genes: the end of genetic privacy?").

The researchers' intentions were honourable. They have not revealed these identities, and the original data has been adjusted to make a repeat using the same technique impossible. All they wanted to do was expose privacy issues.

Consider them exposed. It is clear that genomics has entered a new phase, similar to that which social media went through a few years ago, when concerns were raised about people giving away too much personal information.

What happens when the same applies to our DNA? Having your genome open to public scrutiny obviously raises privacy issues. Employers and insurers may be interested. Embarrassing family secrets may be exposed.

But overall, personal genetic information is probably no more revealing than other sorts. In fact there are reasons to believe that it is less so: would an insurance company really go to the trouble of decoding a genome to discover a slightly elevated risk of cancer or Alzheimer's disease?

The available evidence suggests not. In 2006, Harvard University set out to sequence the genomes of 100,000 volunteers and make them publicly available, along with personal information such as names and medical records. One of the goals was to see what happens when such data is open to all. The answer seems to be "not a lot". So far this Personal Genome Project has published 148 people's full genomes. Not one volunteer has reported a privacy issue.

This is not a reason for complacency, but it suggests that our genomic secrets are less interesting to other people than we might like to believe.

Sao Paolo, Brazil (CNN) -- A fire swept through a popular nightclub in southern Brazil on Sunday, killing at least 245 people, state media reported, citing police.

The death toll was expected to climb as firefighters continued to pull bodies from the Kiss nightclub in Santa Maria, said Col. Adilomar Silva, the regional coordinator of civil defense.

Most of those killed appeared to have died of smoke inhalation, Silva said. Hundreds are believed to have been injured, though an exact count was not immediately available.

Many people were trampled in the panic to leave the club, one security guard told CNN affiliate Band News.

Families and friends searching for information were outside a nearby sporting complex, where bodies were taken for identification, the state-run Agencia Brasil reported.

Police described it as the worst tragedy ever to affect Brazil's Rio Grande do Sul state, Band News said.

The fire started at about 2 a.m. after the acoustic insulation in the Kiss nightclub caught fire, Silva said.

There was a pyrotechnics show going on inside the club when the fire started. Authorities stopped short of blaming it for the blaze, saying the cause was still under investigation.

The incident called to mind a 2003 nightclub fire in Rhode Island where pyrotechnics used by the heavy metal band Great White ignited a blaze that killed more than 90 people.

Pyrotechnics were also involved in a 2004 night club fire in Argentina that killed 194 people and a 2009 explosion at a night club in Russia that left more than 100 dead.

The Kiss nightclub is popular with young people in Santa Maria, drawing between 2,000 and 3,000 people a night on the weekends.

The blaze broke out during a weekend when students were celebrating the end of summer. Students at many Brazilian universities return to school on Monday.

Santa Maria is home to the Federal University of Santa Maria as well as a number of other private universities and colleges.

Brazilian President Dilma Rousseff, who has been in Chile for a regional summit, was expected to come to Rio Grande do Sul, the state government said in a statement.

CNN's Catherine E. Shoichet contributed to this report from Atlanta.

Dozens of stranded Arizona hikers rescued

TUCSON, Ariz. Teams on the ground and in the air rescued dozens of hikers who were stranded in an Arizona canyon after heavy rains flooded trails, authorities said.

Forty to 50 adults and children were stranded Saturday along various sections of Bear Canyon northeast of Tucson as the waters rushed down mountainsides, the Pima County Sheriff's Department said.

A series of 911 calls from hikers sparked a rescue operation involving teams on the ground and in a helicopter,

The first group of hikers was led out of the canyon in the Catalina Mountains in the late afternoon and the last group well after dark, deputy Tom Peine told the Arizona Daily Star.

Some of the hikers said they were stranded when a river swelled to a raging torrent in a matter of minutes.

"I've never seen anything like this," hiker Jesse Boyd told KGUN-TV. "I've gotten caught in rain out here, but nothing to the point where I had to be rescued."

With some hikers, rescuers used a technique that involved roping them together with flotation devices to help get them through high water. Some of the hikers were flown out by helicopter.

"(A) rescue team member was behind us with a hand on that flotation device," Michael Rolland told KVOA-TV after being aided by rescuers. "They strung a rope across, and so we had to grab the rope and sidestep across the river."

Peine said that the hikers might not have realized that rains at higher elevations could cause canyon flooding long after the down pour ends.

Authorities: 245 Dead in Brazil Nightclub Fire

A fire swept through a crowded nightclub in southern Brazil early Sunday, killing at least 180 people and leaving hundreds injured, police and firefighters said.

Sandro Meinerz, a spokesman for the police in the city of Santa Maria, told local media that the fire broke out at the Kiss club while a band was performing. He said at least 200 people were injured.

The cause of the fire is not yet known, officials said. The total number of victims is still unclear and there may be hundreds injured, Civil Police and regional government spokesman Marcelo Arigoni told Radio Gaucha.

Arigoni told the radio station a truck carrying 70 bodies had arrived at the Municipal Sports Center, which was being used as an improvised morgue.

Diario de Santa Maria reported that the fire started at around 2 a.m.

Rodrigo Moura, whom the paper identified as a security guard at the club, said it was at its maximum capacity of between 1,000 and 2,000, and partygoers were pushing and shoving to escape.

Ezekiel Corte Real, 23, was quoted by the paper as saying that he helped people to escape. "I just got out because I'm very strong," he said.

"Sad Sunday", tweeted Tarso Genro, the governor of the southern state of Rio Grande do Sul. He said all possible action was being taken and that he would be in the city later in the day.

Santa Maria, at the southern tip of Brazil near the borders with Argentina and Uruguay, is a major university city with a population of around a quarter of a million.

Your molar roots are leftovers from Homo erectus

TALK about exploring your roots. Longer lifespans mean our adult teeth erupt later than they did in our early ancestors, but the memo didn't make it to the roots of our molars. They develop at the same pace as they did in Homo erectus.

Christopher Dean and Tim Cole at University College London studied the microscopic structure of adult molars to reconstruct the pace of their development, much like tree rings can be used to build a picture of tree growth. They found that the roots of chimpanzee molars go through a growth spurt as the teeth erupt through the gum - probably to provide more stability for biting and chewing. The same thing happened in early hominins, but not in modern humans: by the time our molars arrive, their roots have been fully developed for at least a year.

Dean and Cole found an explanation in Homo erectus, a species who lived between 1.8 million and 300,000 years ago. H. erectus gained its molars at exactly the same age as our molar roots have their growth spurts. Or as Dean puts it: "Our roots are stuck in the past."

In humans, he says, root growth spurts are merely a hangover from an early stage of evolution. We retain molar roots like H. erectus because the growth spurts use too little energy for natural selection to weed them out (PLoS One, doi.org/j8w).

H. erectus had a bigger brain and smaller teeth than its ancestors. Some believe, controversially, that these features reflected big dietary changes, including eating the first cooked food, which would have been easier to chew while supplying more energy.

The new study may find favour with critics of the controversial "cooked food hypothesis". It shows that H. erectus still required an early molar root growth spurt - presumably to prepare its teeth for heavy-duty chewing.
