Want to predict someone's next move, or know if someone is telling you a lie? Learn to read body language like a poker pro.
Olivia "Liv" Boeree is a poker player, TV presenter and model from England who won the 2010 European Poker Tour in Sanremo. Born in Kent, Boeree studied at Ashford School before going on to earn a First Class Honours degree in Physics with Astrophysics at the University of Manchester. She was the #1 ranked female player on the Global Poker Index as of November 2015, and #6 on the female all-time live poker winnings list.
Boeree was a keen guitar player in her early twenties, specializing in the heavy metal genre. In University she played lead guitar in the band Dissonance, and in 2006 she briefly featured as lead guitarist for rock/goth band Nemhain before starting her career in poker.
Boeree also modeled in her early twenties for rock and alternative lifestyle features.
Boeree was introduced to the poker industry when she was selected as one of five contestants for the reality TV show Ultimatepoker.com Showdown, which aired on Five in Autumn 2005.
After the show, Boeree began playing poker regularly at the Gutshot Club in London, and from there became an on-screen reporter for Gutshot TV at the World Series of Poker in Las Vegas. Soon after she became the host of Challenge TV's on-line coverage of the European Poker Tour, also appearing as a reporter for the World Series of Poker Europe on WorldSeriesofPoker.com.
On 21 April 2010, Boeree won the European Poker Tour main event in San Remo, at the time the largest ever poker tournament held on European soil. Boeree won €1,250,000 and thereby became the third woman ever to win an EPT title.
She has shown continuous success on the EPT circuit with twelve Main Event cashes to date. Other notable results include a 2nd place in the 2014 UKIPT Edinburgh Main Event a 3rd place in the EPT Barcelona High Roller event for €391,000 in August 2015.
Boeree has been a member of Team PokerStars Pro since September 2010. Her total live tournament winnings exceed $3,000,000.
In February 2016 she was announced as the Team Manager of the Global Poker League team "The London Royals".
Liv Boeree: When it comes to body language, it's never an exact art. The things I'm going to suggest, they're all guidelines. But that said there are some certain things that as a poker player I'll look for. And the most important thing is, first of all, to get a baseline of somebody. It's impossible to tell whether the behavior someone is showing is meaningful or not if you don't know how they naturally behave. So the first thing I'll do when I sit down at the table is look at what my opponents are doing when they're not in a hand: are they naturally quite gregarious, are they confident when they interact with the waitress, or are they naturally quite quiet and shy? How do they sit? Are they naturally closed off? Are they very languishing”—that kind of thing?
And once I've got an idea of their baseline outside of a hand then I look to see how they deviate from that when they're actually in the middle of playing or in a tense situation. In general what you want to look for in both poker—but also when you're trying to figure out if someone is lying—is their comfort level, if they seem authentic. As a rule of thumb, humans are actually quite good at picking up authenticity or if someone is being disingenuous. So that's the thing to look out for, and there are some like classic behaviors that I've noticed people do at the table where—if you see them suddenly making a point of making themselves bigger, where they're naturally sitting like this and now they're sort of puffing up, that's more often than not a false confidence that they're trying to show. Most people do try to stay very constant. So you really do notice a behavior, particularly against someone who seems to play quite regularly, the chances are that they're aware of their behavior, so they're probably trying to mislead you.
But another rule of thumb that I like to follow is: the first thing you learn as a kid, usually, when you lie is “liars won't look you in the eye,” so what do kids do to overcompensate? They'll look you in the eye. And similarly people are very aware of their faces, this part of their body, if they're trying to be dishonest, but what they're not thinking about is the rest of their body. So the lower down on the body that you're looking at, the more reliable the information is.
So if you think about when you're excited about something, generally speaking you'll bounce around and you can't keep still, and we call it “happy feet” in poker. The feet are often the most reliable thing to look at on your opponent because they might be completely stoic in their face but their feet are bouncing around—it's usually a sign that they have a really strong hand. But similarly if they're sort of smiling and chatty but their feet all of a sudden tuck themselves around the table or around the chair legs, something's up there. So as a rule of thumb, look for the rest of someone else's body more than their face if you're trying to figure out if they're telling you the truth or not.
A good poker face can win you a fortune or help you sell a difficult lie, but that term might be leading us all astray. For poker champ Liv Boeree, calling someone's bluff isn't about their face at all, it's often much more about their body as a whole—and one part in particular. "The feet are often the most reliable thing to look at on your opponent because they might be completely stoic in their face but their feet are bouncing around," she says. We're all hyper aware of our faces as a primary point of communication, but our bodies are speaking more loudly than we may realize. Typically, "the lower down on the body that you're looking at, the more reliable the information," she says. Keep in mind, reading body language is an art not a science, but thanks to Boeree's years of experience at the poker table she highlights some classic behaviors of bluffers, and reliable strategies for those who want to call them out.

Erin Meyer explains the keeper test and how it can make or break a team.
- There are numerous strategies for building and maintaining a high-performing team, but unfortunately they are not plug-and-play. What works for some companies will not necessarily work for others. Erin Meyer, co-author of No Rules Rules: Netflix and the Culture of Reinvention, shares one alternative employed by one of the largest tech and media services companies in the world.
- Instead of the 'Rank and Yank' method once used by GE, Meyer explains how Netflix managers use the 'keeper test' to determine if employees are crucial pieces of the larger team and are worth fighting to keep.
- "An individual performance problem is a systemic problem that impacts the entire team," she says. This is a valuable lesson that could determine whether the team fails or whether an organization advances to the next level.
A study finds 1.8 billion trees and shrubs in the Sahara desert.
- AI analysis of satellite images sees trees and shrubs where human eyes can't.
- At the western edge of the Sahara is more significant vegetation than previously suspected.
- Machine learning trained to recognize trees completed the detailed study in hours.

Area in which trees were located
Credit: University of Copenhagen<p>As important as trees are in fighting climate change, scientists need to know what trees there are, and where, and the study's finding represents a significant addition to the global tree inventory.</p><p>The vegetation Brandt and his colleagues have identified is in the Western Sahara, a region of about 1.3 million square kilometers that includes the desert, <a href="https://en.wikipedia.org/wiki/Sahel" target="_blank">the Sahel</a>, and the <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/subhumid-zones" target="_blank" rel="noopener noreferrer">sub-humid zones</a> of West Africa.</p><p>These trees and shrubs have been left out of previous tabulations of carbon-processing worldwide forests. Says Brandt, "Trees outside of forested areas are usually not included in climate models, and we know very little about their carbon stocks. They are basically a white spot on maps and an unknown component in the global carbon cycle."</p><p>In addition to being valuable climate-change information, the research can help facilitate strategic development of the region in which the vegetation grows due to a greater understanding of local ecosystems.</p>

Credit: Martin Brandt/University of Copenhagen<p>There's been an assumption that there's hardly enough vegetation outside of forested areas to be worth counting in areas such as this one. As a result the study represents the first time a significant number of trees — likely in the hundreds of millions when shrubs are subtracted from the overall figure — have been catalogued in the drylands region.</p><p>Members of the university's Department of Computer Science trained a machine-learning module to recognize trees by feeding it thousands of pictures of them. This training left the AI be capable of spotting trees in the tiny details of satellite images supplied by NASA. The task took the AI just hours — it would take a human years to perform an equivalent analysis.</p><p>"This technology has enormous potential when it comes to documenting changes on a global scale and ultimately, in contributing towards global climate goals," says co-author Christian Igel. "It is a motivation for us to develop this type of beneficial artificial intelligence."</p><p>"Indeed," says Brandt says, "I think it marks the beginning of a new scientific era."</p>
Looking ahead and beyond<p>The researchers hope to further refine their AI to provide a more detailed accounting of the trees it identifies in satellite photos.</p><p>The study's senior author, Rasmus Fensholt, says, "we are also interested in using satellites to determine tree species, as tree types are significant in relation to their value to local populations who use wood resources as part of their livelihoods. Trees and their fruit are consumed by both livestock and humans, and when preserved in the fields, trees have a positive effect on crop yields because they improve the balance of water and nutrients."</p><p>Ahead is an expansion of the team's tree hunt to a larger area of Africa, with the long-term goal being the creation of a more comprehensive and accurate global database of trees that grow beyond the boundaries of forests.</p>
Water may be far more abundant on the lunar surface than previously thought.
- Scientists have long thought that water exists on the lunar surface, but it wasn't until 2018 that ice was first discovered on the moon.
- A study published Monday used NASA's Stratospheric Observatory for Infrared Astronomy to confirm the presence of molecular water..
- A second study suggests that shadowy regions on the lunar surface may also contain more ice than previously thought.
Credits: NASA/Daniel Rutter<p>Still, it's not as if the moon is dripping wet. The observations suggest that a cubic meter of the lunar surface (in the Clavius crater site, at least) contains water in concentrations of 100 to 412 parts per million. That's roughly equivalent to a 12-ounce bottle of water. In comparison, the same plot of land in the Sahara desert contains about 100 times more water.</p><p>But a second study suggests other parts of the lunar surface also contain water — and potentially lots of it. Also publishing their findings in <a href="https://www.nature.com/articles/s41550-020-1198-9#_blank" target="_blank">Nature Astronomy</a> on Monday, the researchers used the Lunar Reconnaissance Orbiter to study "cold traps" near the moon's polar regions. These areas of the lunar surface are permanently covered in shadows. In fact, about 0.15 percent of the lunar surface is permanently shadowed, and it's here that water could remain frozen for millions of years.</p><p>Some of these permanently shadowed regions are huge, extending more than a kilometer wide. But others span just 1 cm. These smaller "micro cold traps" are much more abundant than previously thought, and they're spread out across more regions of the lunar surface, according to the new research.</p>

But if there is, it would mean that water would be much more accessible to astronauts, considering they wouldn't have to travel into deep, shadowy craters to extract water.</p><p>Greater accessibility to water would not only make it easier for astronauts to get drinking water, but could also enable them to generate rocket fuel and power.</p><p style="margin-left: 20px;">"Water is a valuable resource, for both scientific purposes and for use by our explorers," said Jacob Bleacher, chief exploration scientist in the advanced exploration systems division for NASA's Human Exploration and Operations Mission Directorate, in a statement. "If we can use the resources at the Moon, then we can carry less water and more equipment to help enable new scientific discoveries."</p>
