From Birth, Our Microbes Become As Personal As A Fingerprint

We may not see them, but we need them.

Look in the mirror, and you won't see your microbiome. But it's there with you from the day you are born. Over time, those bacteria, viruses, and fungi multiply until they outnumber your own cells 10 to one.

As babies, the microbes may teach our immune systems how to fight off bad bugs that make us sick and ignore things that aren't a threat.

We get our first dose of microbes from our mothers, both in the birth canal and in breast milk. Family members tend to have similar microbiomes.

"The mother's microbiome has actually poised itself over nine months to basically become the prime source of microbes to the infant," says Lita Proctor, director of the Human Microbiome Project at the National Institutes of Health.

But ultimately each person's microbiome seems to be unique, perhaps as personal as a fingerprint.

As the microbes colonize our bodies, they pick specialized real estate. The mouth, with all those moist nooks and crannies, is home to one of the most diverse habitats, like the Amazon jungle.

Wet places like our armpits are lush, too. But they have different microbes than those in the mouth.

The armpit microbes feast on nutrients in sweat, Proctor says, and produces antimicrobial compounds to protect the skin against harmful microbes.

Other body parts are like the Sahara Desert to your microbes. That forearm skin, for example, is dry — very dry. But even that driest habitat is brimming with microbes.

Feet have oily parts and dry parts, and those wet parts that the foot fungus just loves.

But the biggest habitat is the gut. It hosts the most complex and diverse group of microbes. Everything that microbes are doing elsewhere in the body, they're doing in the gut, in spades.

Diverse as these habitats are, the microbes on the various body parts communicate with each other and with our cells. Scientists have started eavesdropping on those conversations, and have started testing them as possible treatments for diseases like Crohn's, multiple sclerosis, and asthma.

This research is all really new. No one knows for sure what most of our microbes are doing. But many scientists now think that if we're going to remain healthy, we have to maintain the health and well-being of the ecosystems for our microbes.

British royal baby's birth drafted as phishing bait

It may be old news now, but hackers are still using news of the U.K. royal baby's birth to entice people into clicking on malicious links, according to researchers at Trend Micro.

When the official announcement was made on July 22, the researchers spotted plenty of spammed messages related to the birth of Price George. In a statement, they described the speed with which this spam hit the Internet as "remarkable."

"These messages appear to be from ScribbleLive, a service that provides real-time engagement platforms.

The offer, of course, is false, and clicking on links in the email will only trigger multiple redirections that are typical among Blackhole exploit kit (BHEK) spam runs," the researchers said.

BHEK is a page that cybercriminals use to determine what software versions are used by a victim so that the page can deliver the "correct" exploit. Generally, people using outdated software are more at risk of being caught by exploits.

In this case, the script that triggers the redirections is detected as JS_OBFUSC.BEB, the researchers said. This particular exploit targets two vulnerabilities in Java: CVE-2013-1493 and CVE-2013-2423. Both of these vulnerabilities have been patched by Oracle, though many people still run on older versions of Java.

Trend Micro described this technique of taking advantage of current affairs as a social engineering lure, adding that they often come in the form of highly publicized events. The researchers gave the Boston Marathon incident and the election of Pope Francis as prime examples. What's more, they said, hackers take advantage of more than one big news story at a time.

"This particular BHEK run is not limited to the royal baby alone. Other spammed messages took advantage of the controversy surrounding the upcoming sci-fi film Ender's Game," they said.

"While these messages are made to look like an article from CNN, clicking on links will trigger the same redirections as that of the royal baby spam."
