Fire-hardened House Offers Lessons on Rebuilding Los Angeles

The house that Michael Kovac built is the only one on his street still standing after a huge fire raced through his Los Angeles neighborhood.

Now this architect says the city needs to learn from homes like his as it begins to rebuild.

"I think we always knew a fire was coming here," he said of the ridgeline in Pacific Palisades where his house sits.

Kovac and his wife, Karina Maher, who describe themselves as "avid environmentalists," designed and constructed their home with that risk in mind.

The walls are covered with non-flammable cement fiber siding, the windows are insulated to have the highest degree of protection against heat, the vents are covered in metal mesh and the fireproof roof is topped with soil and vegetation, AFP reported.

Instead of a lawn, the garden is designed as a "defensive space," where a bed of volcanic rocks is dotted with agave, dwarf olive trees and mother-in-law's cushions -- a striking spherical cactus.

All of it is protected by a sprinkler system that can spray fire retardant to slow the spread of flames.

"If most of the houses were built to something closer to this standard, I think the fire could have been contained," Kovac told AFP of the blaze that erupted on January 7.

Like many in Los Angeles, the 62-year-old was astounded by just how destructive the wind-driven fires were, with two major blazes razing around 40,000 acres (16,000 hectares) and leveling thousands of buildings.

As the city gradually turns its attention towards the long, slow process of rebuilding, Kovac hopes it will do so with fire resiliance in mind.

Many houses in the western United States have timber frames, and a wholesale switch to something less vulnerable like brick is unlikely, as availability and cost are key drivers in construction choices.

But even if the frame stays the same, hardening its cover doesn't have to break the bank, says Kovac.

"The choice to use, say, a cement siding instead of a wood siding, that's almost a cost neutral thing," he said.

Footage from his home's security cameras shows red-hot embers spraying all over the property -- the same embers that allowed the fire to take hold of so many homes on his street.

But not Kovac's.

"At that point you have to dismiss too much of it being luck. I mean, when it's enveloped by embers and surrounded by flames... it's down to the material choices and the systems to protect the house," he said.

Maher, a doctor who specializes in the effects of climate change on human health, says the fire was an obvious consequence of the way we are messing with our planet.

"We know the solutions to slow it down, but we also know the solutions to adapt, and that's what we all need to do," she said.

The devastation wrought by the fires was awful, says Yana Valachovic, a specialist in fire-resistant construction at the University of California, but it now presents an opportunity.

Protecting a home from the ember showers that set so many houses ablaze is among the most pressing considerations, she said.

That means hardening or stopping any ingress points, like vents.

Other important considerations are using tempered glass -- which is heat-resistant -- and rethinking the way a garden is laid out.

"Fire adaptation doesn't require a huge investment, it just requires us living a little differently," Valachovic said.



Face of 400-Year-Old 'Vampire' Recreated

The face of a "vampire", whose remains were posthumously mutilated to prevent them from rising from the dead, can be seen for the first time in more than 400 years, reported Sky News.

Discovered in a grave at Racesa, a fortress in eastern Croatia, the body had been exhumed, beheaded and reburied face down beneath heavy stones.

And since the desecration cannot be explained by environmental factors, experts believe it was done to stop the dead man returning as a vampire.

Now the face of the deceased can be seen for the first time in centuries, after scientists rebuilt his likeness from his skull.

Archaeologist Natasa Sarkic, part of the excavation team, said the fear inspired by the man in death may stem from the fear he inspired in life.

She said: “Bioarchaeological analysis showed that this man often participated in violent conflicts, and died a violent death. He experienced at least three episodes of serious interpersonal violence during his lifetime.”

“One of those attacks left his face disfigured, which could cause fear and repulsion, leading to social exclusion. Before even recovering from the penultimate trauma, he sustained a final fatal attack,” she revealed.

“Individuals who died violently, behaved violently in life, or were considered sinful or socially deviant, were believed to be at risk of becoming vampires,” she continued.

“He may have been regarded as a 'vampire', or a supernatural threat due to his facial disfigurement and his marginal lifestyle, characterized by repeated interpersonal violence,” Sarkic explained.

She said such beings were thought to be restless, vengeful, and capable of harming the living, spreading disease and killing people or livestock.

Sarkic said that, in the Slavic tradition, the soul remains attached to the body for about 40 days after death.


Caffeinated Beverages May Help Protect the Brain, Study Says

Drinking a few cups of caffeinated coffee or tea every day may help in a small way to preserve brain power and prevent dementia, researchers reported on Monday.

People with the highest daily intake of caffeinated coffee had an 18% lower risk of developing dementia compared to those with the lowest such intake, according to a study based on responses to questionnaires by 132,000 U.S. adults spanning four decades.

The study, published in JAMA, also found that the people with the highest intake had a lower rate - by nearly 2 percentage points - of ‌self-perceived memory ‌or thinking problems compared to those with ‌the ⁠lowest intake.

Results were ‌similar with caffeinated tea, but not with decaffeinated beverages, the researchers said.

While the findings are encouraging, the study does not prove caffeine helps protect the brain, they said.

The magnitude of caffeine's effect, if any, was small, and there are other better-documented ways to protect cognitive function as people age, study leader Dr. Daniel Wang ⁠of Harvard Medical School said in a statement.

Lifestyle factors linked with lower risks of ‌dementia include physical exercise, a healthy diet ‍and adequate sleep, according to previous ‍research.

"Our study suggests that caffeinated coffee or tea consumption can ‍be one piece of that puzzle," Wang said.

The findings were most pronounced in participants who consumed two to three cups of caffeinated coffee or one to two cups of caffeinated tea daily, the researchers reported.

Those who drank caffeinated coffee also showed better performance on some objective tests of cognitive function, according to the ⁠study funded by the National Institutes of Health.

Further research is needed to validate the factors and mechanisms responsible for the findings, the researchers said.

They noted that bioactive ingredients in coffee and tea such as caffeine and polyphenols have emerged as possible factors that reduce nerve cell inflammation and damage while protecting against cognitive decline.

"We also compared people with different genetic predispositions to developing dementia and saw the same results - meaning coffee or caffeine is likely equally beneficial for people with high and low genetic risk of developing ‌dementia," study coauthor Dr. Yu Zhang of the Harvard T.H. Chan School of Public Health said in a statement.
