There’s a lot of ground covered in today’s demonstrate. We’re explaining how a metro conductor might’ve saved lives during an seeming terrorist attack in Russia. We’re looking at the potential risk for a world outbreak of illnes — and what’s being done to address it. And we’re introducing the people who could become the first Winter Olympians from Afghanistan. Home buying in the U.S. and brand-new employs for thermochromic ink round down the program .
An explosion took place between two subway stations in St. Petersburg, Russia, yesterday and officials say it was a terrorist attack .
This happened just after 2:30 p.m. in Russia’s second most important municipality. Russian officials say one explosive design went off on a moving subway civilize. It killed at least 10 people and wounded dozens of others. A second invention was reportedly saw and defused at another depot.
St. Petersburg’s entire set plan, which carries more than two million people a daylight, was shut down. And a meter we grow this picture , no group had claimed responsibility for the attack .
The conductor of the damaged improve might have saved lives. Russian investigates say he stopped the develop moving after the explosion rather than stopping in the passageway. Because he made it to the next terminal, surviving passengers were able to get out and saviors were able to help the injured .
Russian President Vladimir Putin was in St. Petersburg at the time, speaking at a media event. A Russian official advocated the point and timing of the blast might have been intended to coincide with Putin’s call .
Several terrorist attacks were carried in Russia earlier this century, but the commonwealth has had relatively limited in recent years .

AZUZ( voice-over ): Ten-second trivia :

Epidemic, pandemic, polemic or epistemic ?
When something like a disease is pandemic, it spread over a very large neighborhood and feigns many people .

AZUZ: When it comes to potential illnes pandemics, a public health expert says we’re simply as procure as the world’s weakest country and there are a lot of countries with relatively weak health systems and economies. Following the Ebola outbreak of 2014, the international spread of the Zika virus, and the world-wide dissemination of other sickness like swine flu and SARS, experts are warns that civilians and health officials need to be prepared for another outbreak. Of what? They don’t know hitherto.
But they’re very concerned about various concludes: one, the world’s person is flourishing and so is the number of people who live close to each other in cities. Two, beings are traveling more each year. That can circulate troubles to non-eu countries. Three, many nations were disease outbreaks are likely are poor and they have fewer doctors and nurses to menace entire populations.
Of trend, there are many other factors like its first year it takes to develop vaccines. But “then theres” plans forming worldwide to take on cankers when they start to spread .

SONIA SHAH, SCIENCE JOURNALIST AND AUTHOR: We can’t know which pathogen is going to cause the next, kind of, big-hearted outbreak, but we do know where these circumstances happen or more likely to happen because we know how it happens. So, we know that in places where there’s rapid urbanization, a lot of shanties, intensified livestock production, a lot of breath contacts, all of these different ways in which new pathogens can develop, we know that’s how it happens.
So, we are going to be able look at a delineate and we can see, well, where are the hotspots where this is most likely to occur and we can do intense surveillance in those residences and beings are already had begun to do that in kind of an ad hoc path. But I think that’s something “weve been” are going to step up in the future .

AZUZ: Next, home hunters, millennial edition. The timing: it’s residence buying season in the U.S. Spring is usually the busiest age of its first year for real estate.

Harmonizing to a mortgage investigate busines, millennials are now the largest group of residence buyers, though experts believe in the past that the generation “d rather” payment than buy .
The challenge: they are experiencing a lot of competitor, in particular against people who bought a dwelling before and may have more recognition and more coin. There’s a shortage of available dwellings in America, especially starter residences, lower priced homes that often fall within the first time buyer’s plan. Home values are up and that’s led to entreat battles between millennials and everyone else .
One silver lining for younger buyers: interest rates are lower than they were for their parents. Experts say to get an side, first time purchasers should set a budget, stir priorities for what they crave in a home and get pre-approved for a lend .
A British decorator has encountered a direction to infuse chemistry with every day fabrics, generating thermochromic candles, dres, carrying examples. Thermochromic describes something that can change colour when it’s heated or coldnes. The ink isn’t cheap. A backup list for $1,500. A leather cardholder over $200.
But the technology could be used far beyond pattern .

LAUREN BOWKER, MATERIAL ALCHEMIST: THE UNSEEN: Complexion is just a universal speech, they’ve often is employed very intelligently.
Essentially, what we do here in The Unseen is we imagine data through the language of colour on a material, from a skin that can change coloring, to home situations, it could be a car decorate or concrete that can tell you your carbon emission grade. The honcho portion that allows you to understand more about your mentality and the chemical agents( ph) from it by informing through a simple shade change .
SUBTITLE: Lauren has created different perils that can be used on virtually any information. These inks react to invisible changes around us like hot, distres, sweat and light-footed .
BOWKER: We have many different inks that respond in different ways and dye and when you start to realize that this world is full of so much invisible and unseen data and you start to think, well, how can you harness that data? It opens all of these different possibilities and uses for a medium like colouring .
SUBTITLE: Bandages can tell you they need to be changed. Hair color reacts to temperature. Leather that adapts with the transformation of air pressure .
BOWKER: Quite a lot of projects we worked on are real life-changing produces and I think, you are familiar with, we should be able to create something for health care and then likewise generate something for mode week. Quality use color in such profound modes for camouflage, for communication. Trees change dye with the seasons. Fruit changes its hue when it goes off.
Science is getting to the point where it can imitative quality to a degree. How can we make those together and make not just beautiful concoctions but events within the world that stress( ph) the knockout of and wonder of quality. When you start to think of using shade as different languages, it opens up numerous obstructions that perhaps have not been communicated before .

AZUZ: So, Vantablack, the Guinness World Record for the darkest manmade substance, isn’t technically a colouring. It’s a varnish of thousands of minuscule carbon tubing. Vantablack assimilates 99.96 percent of visible light. So, when something’s contained within it, our eyes perceived as flat, even if it’s a three-dimensional object.
The coating is fantastically expensive. A watch attained with Vantablack expenditure nearly $100,000. But the coating’s ability to suppress illumination could oblige happenings like cameras and telescope more sensitive to swoon ignite.
So, it could be ad-vanta-geous from that vanta-ge degree. But to molt more light on its usages, Vantablack is not the brand-new black. Even if you alighted on the way to style into fashion( ph ), you can’t use Vantablack to shroud a shroud or conceal a robe. It’s readily mar if you bump or scratch it, so it’s surely not good for shedding color .
