A new generation of leaders for new global challenges
In collaboration with the Clinton Global Initiative University
What’s your commitment? How to become an effective change-maker.
As an activist, public health professor, mom, author, and Vice Chair of the Clinton Foundation, Chelsea Clinton sure is pretty busy. Here, she explains to us that there is a divide between wanting to make the world a better place and actually having a direction and a unique goal to make it happen. In order to help others both see and meet their goals, the Clinton Foundation launched Clinton Global Initiative University (CGI U) to give mentorship to those looking to make positive change. This video, part one in a series, is a great introduction to CGI U and to Chelsea's overall worldview. You can find out more about CGI U right here.
Learning is more than retaining information—how mentors make the difference
Is America's achievement gap crisis caused by long summer vacations? "In lower income neighborhoods, kids forget anywhere from two-and-a-half to three-and-a-half months of what they learned during the school year over the summer, while their middle-class peers break even or even make gains," says Karim Abouelnaga, CEO of Practice Makes Perfect. This startling statistic is why he started a different kind of summer school, one based on a chain of near-peer mentors, where kids are connected with college students and college students are connected with teaching professionals. "This model, where everyone is sort of a participant but also a beneficiary, creates this win-win-win situation for everyone, making summer school a lot more fun and exciting." Why do some eighth grader students only have a fourth grade reading level? Theoretically speaking, they’ve only been in school for half the time, says Abouelnaga.

How financial innovation is giving cities jobs, wealth and health
Ever since President Jimmy Carter put solar panels on the White House in 1979, innovators and green-minded politicians have been trying to unlock the enormous benefits of energy efficiency across America. But those benefits have remained illusive for two reasons, says BlocPower founder Donnel Baird: financial constraints and engineering complexities. Aged infrastructure like power plants cost us a lot, financially and environmentally. Our best shot at efficiency is by "greening" existing buildings so they can create power locally, rather than burning fossil fuels at a plant and transmitting electricity over long distances, wasting much of it along the way. The problem is that greening isn't cheap: it needs building analysis, and lots of capital to make the initial changes, which not all building owners have. Baird's startup BlocPower has developed technology to lower the cost of building analysis by a huge 95 percent, and matches investors with building owners—it turns out greening buildings is a very profitable investment. Here, Baird explains the details of how updating infrastructure can bring health and wealth to a city: "We know that energy efficiency is going to reduce energy costs for building owners. It’s going to create local jobs. It’s going to reduce our dependence and reliance on foreign oil. And it’s just going to be awesome all around for the environment."
How one Ugandan is fighting human trafficking in Africa—and the U.S.
After fleeing the Lord's Resistance Army in her native Uganda, Igoye came the University of Minnesota. There she began finding resources to combat the scourge of human trafficking. Igoye was so determined to make a difference that she stopped buying food—choosing to eat at university events instead—which allowed her to save money. With her first $1,000 of savings, she supplied her native Ugandans with 23,000 books, knowing that education is an essential part of improving communities and stopping human trafficking. Through the Clinton Global Initiative University, Igoye is committed to building care centers for survivors of human trafficking and training law enforcement to better recognize and combat the illegal activity.
How 'Violence Against Women Centers' are reforming Pakistan’s deadly cultural norm
Approximately 5,000 women die at the hands of domestic violence in Pakistan each year, and thousands more are maimed or disabled. In the socially conservative country, justice is heavily compromised as the reporting of rape, sexual assault, and domestic violence carries a social stigma, the prosecution process is biased and fragmented, and the conviction rate is just 1-2.5%. In 2014, global conflict advisor Hafsah Lak asked herself: what can we do to provide survivors a real and effective justice delivery system? While working at the Punjab Chief Minister’s Strategic Reforms Unit (formerly, known as Special Monitoring Unit - Law and Order) in Punjab, Pakistan, she co-drafted the Punjab Protection of Women Against Violence Act of 2016 and Punjab Women Protection Authority Act 2017. When the former Act was passed into law, it was hit with heavy conservative backlash. Recognizing that reform cannot be carried out by people who do not share the vision, Lak worked as a project lead at the Strategic Reforms Unit to create Pakistan's first-ever Violence Against Women Center (VAWC), which opened on March 25, 2017 and has successfully resolved over 900 cases of violent crimes against women thus far. The VAWC has streamlined the case file process all under one roof (removing all roadblocks to reporting crimes) and is staffed by at least 60 all-female staff including 30 female police officers, 5 female medical officers, plus dedicated prosecutors and psychologists who were hired for their commitment to protecting women, and to providing a real deterrent for perpetrators of gender-based violent crimes.

How the foster care system fails so many kids—and how we can do better
When it comes to life after foster care, there is typically not a lot of hope on the horizon, says Sixto Cancel, who has been in and out of the foster care system since he was 11 months old. He was lucky enough to take part in programs that set him up for an independent life when he turned 18—how to manage finances, find a job, apply for an apartment, buy a car—but his story is the exception, not the rule. The stats are not good: 20 percent of young people in foster care will experience homelessness within the first two years of leaving the system. 50 percent are underemployed. Only 3 percent earn a bachelor's degree. These negative outcomes are the reason Cancel founded Think of Us, a non-profit platform that gives vulnerable youths tools and resources to plan their life, and empowers them to build a network of adult mentors they trust.

- Sci-fi visions of Mars have changed over time, in step with humanity's own obsessions.
- Once the source of alien invaders, the Red Planet is now deemed ripe for terraforming.
- Here's an extreme example: Mars with exactly as much surface water as Earth.
Misogynists in space
Mars – and Martians – were a staple of 1930s pulp science fiction.

"Oh, my God, it's a woman," he said in a tone of devastating disgust.
"Stowaway to Mars" hasn't aged well. First serialised in 1936 as "Planet Plane" and set in the then distant future of 1981, the fourth novel by sci-fi legend John Wyndham (writing as John Benyon) could have been remembered mainly for its charming retro-futurism, if it weren't so blatantly, offhandedly misogynistic.
Fortunately, each era's sci-fi says more about itself than about the future. That also goes for how we see Mars. 'Classic' Martians, like the ones in H.G. Wells' "War of the Worlds," are creatures from a dying planet, using their superior firepower to invade Earth and escape their doom. That trope reflected 19th- and 20th-century fears about mechanized total warfare, which hung like a sword of Damocles over otherwise increasingly placid lifestyles.
Closer inspection of the Red Planet has revealed the absence of green men; and now we're the dying planet – pardon my Swedish. So the focus has shifted from interplanetary war to terraforming the fourth rock from the Sun, creating something all those protest signs say we don't have: a Planet B.
How to keep Mars from killing us
Mars today: red and dusty, dead and deadly.

Cue Elon Musk, who doesn't just build Teslas but also heads SpaceX, a program to make humanity an interplanetary species by landing the first humans on Mars by 2024 as the pioneers of a permanent, self-sufficient and growing colony.
Such a colony would benefit from an environment that doesn't try to kill you if you take off your space helmet. Martian temperatures average at around -55°C (-70°F), and its atmosphere has just 1 percent the volume of Earth's, in a mix that contains far less oxygen. Changing all that to an ecosystem that's more like our own, would be a herculean task.
From Red Mars to Green Mars

So how would Musk go about it? In August 2019, he launched a t-shirt with the two-word answer: 'Nuke Mars'. The idea would be to heat up and release the carbon dioxide frozen at Mars's poles, creating a much warmer and wetter planet – as Mars may have been about 4 billion years ago – though still not with a breathable atmosphere.
Alternatives to nuclear explosions: photosynthetic organisms on the ground or giant mirrors in space, either of which could also melt the Martian poles. However, many scientists question the logistics of these plans, and even whether there is enough readily accessible CO2 on Mars to fuel the climate change that Musk (and others) envision.
Ah, but why stop at the objections of the current scientific consensus? Sometimes, you have to dream ahead to see the place that can't be built yet. In the lobby of SpaceX HQ in Hawthorne, California, Red Mars and Green Mars are shown side by side. The terraformed version on the right looks green and cloudy and blue – Earth-like, or at least habitable-looking.
Or how about a Blue Mars?

But why stop there? This map looks forward to a Mars that doesn't just have some surface water, but exactly as much as Earth – which means quite a lot. No less than 71 percent of our planet's surface is covered by oceans, seas, and lakes. The dry bits are our continents and islands.
In the case of Mars, a 71 percent wet planet leaves the planet's northern hemisphere mainly ocean, with most of the dry land located in the southern half.
Most of the dry land is connected via the south pole but is articulated in two distinct land masses. Both semi-continents are separated by a wide bay that corresponds to Argyre Planitia.
The one in the west is centered on Tharsis, a vast volcanic tableland. To the north, attached to the main land mass, is Alba Mons, the largest volcano on Mars in terms of area (with a span comparable to that of the continental United States).
It's about 6.8 km (22,000 ft) high, which is about one-third of Olympus Mons, a volcano now located on its own island off the northwest coast of Tharsis. At a height of over 21 km (72,000 ft), Olympus Mons is the highest volcano on Mars and the tallest planetary mountain (1) currently known on the solar system. Olympus rises about 20 km (66,000 ft) above the sea level as shown on this map.
A new civilization

Mars's eastern continent is centered not on a plateau, but on a depression that on today's 'dry' Mars is called Hellas Planitia, one of the largest impact craters in the Solar system. On the 'wet' Mars of this map, the crater is the central and largest part of a sea that is surrounded by land, a Martian version of the Mediterranean Sea. Perhaps one day this Medimartian Sea will be the Mare Nostrum of a new civilization.
To the northeast of the circular semi-continent is a large island that on 'our' Mars is Elysium Mons, a volcano that is the planet's third-tallest mountain (14.1 km, 46,000 ft).
The map is the work of Aaditya Raj Bhattarai, a civil engineering student at Tribhuvan University in Kathmandu (Nepal). Talking to Inverse, he said he hoped his map could help further the Martian plans of Elon Musk and SpaceX: "This is part of my side project where I calculate the volume of water required to make life on Mars sustainable and the sources required for those water volumes from comets that will come nearby Mars in the next 100 years."

(1) The tallest mountain in the Solar system, planetary or otherwise, we know of today, is a peak which rises 22.5 km (14 mi) from the center of the Rheasilvia crater on Vesta, a giant asteroid which makes up 9 percent of the entire mass of the asteroid belt.
- Anyone can start a business and be an entrepreneur, but the reality is that most businesses will fail. Building something successful from the ground up takes hard work, passion, intelligence, and a network of people who are equally as smart and passionate as you are. It also requires the ability to accept and learn from your failures.
- In this video, entrepreneurs in various industries including 3D printing, fashion, hygiene, capital investments, aerospace, and biotechnology share what they've learned over the years about relationships, setting and attaining goals, growth, and what happens when things don't go according to plan.
- "People who start businesses for the exit, most of them will fail because there's just no true passion behind it," says Miki Agrawal, co-founder of THINX and TUSHY. A key point of Agrawal's advice is that if you can't see yourself in something for 10 years, you shouldn't do it.
- Laser experiments can reveal precisely how far away an object is from Earth.
- For years scientists have been bouncing light off of reflectors on the lunar surface that were installed during the Apollo era, but these reflectors have become less efficient over time.
- The recent success could reveal the cause of the degradation, and also lead to new discoveries about the Moon's evolution.
NASA's Lunar Reconnaissance Orbiter (LRO) has been orbiting the Moon about a dozen times per day since 2009. The craft carries six high-tech instruments that have helped scientists create detailed maps of the moon, and learn more radiation and temperatures on the lunar surface.
But the craft also carries a rather simple instrument: a reflector the size of a paperback novel.
Over the past decade, scientists have been shooting laser beams from Earth to the LRO's reflector, some 240,000 miles away, hoping to catch a return signal. On Monday, NASA scientists and their French colleagues announced that they successfully received that return signal for the first time.
What can scientists learn by bouncing lasers off the LRO? For one, it reveals precisely how many seconds it takes for photons to travel there and back — an average of 2.5 seconds. Scientists can use this duration to tell exactly how far away an object is. Also, by measuring tiny fluctuations in the duration, they can study subtle movements of the Moon.

The technology isn't quite new. During the Apollo era, astronauts installed on the lunar surface five reflecting panels, each containing at least 100 mirrors that reflect back to whichever direction it's coming from. By bouncing light off these panels, scientists have been able to learn, for example, that the Moon is drifting away from Earth at a rate of about 1.5 inches per year.
"Now that we've been collecting data for 50 years, we can see trends that we wouldn't have been able to see otherwise," Erwan Mazarico, a planetary scientist from NASA's Goddard Space Flight Center in Greenbelt, Maryland, said. "Laser-ranging science is a long game."
NASA's Lunar Reconnaissance Orbiter (LRO)
But the long game poses a problem: Over time, the panels on the Moon have become less efficient at bouncing light back to Earth. Some scientists suspect it's because dust, kicked up by micrometeorites, has settled on the surface of the panels, causing them to overheat. And if that's the case, scientists need to know for sure.
That's where the recent LRO laser experiment comes in. If scientists find discrepancies between the data sent back by the LRO reflector and those on the lunar surface, it could reveal what's causing the lunar reflectors to become less efficient. They could then account for these discrepancies in their models.
Studying the Moon's core
More precise laser experiments could also help scientists learn more about the moon's core. By measuring tiny wobbles as the Moon rotates, past laser experiments revealed that the satellite has a fluid core. But inside of that fluid could lie a solid core — one that might've helped to generate the Moon's now-extinct magnetic field.
However, confirming that hypothesis will require more precise measurements — and the continued success of laser experiments involving the LRO, or reflecting panels installed on the Moon during future missions.
"The precision of this one measurement has the potential to refine our understanding of gravity and the evolution of the solar system," Xiaoli Sun, a Goddard planetary scientist who helped design LRO's reflector, told NASA.
- Steel is fifty times harder than hair, yet shaving razors dull in a hurry.
- A new study finds much of this is caused by hair cracking razors at points of imperfection.
- The findings may lead to new ways of making razors that last longer.
Everybody who shaves regularly knows that most razors only last a few shaves. Given that hair is not nearly as hard as steel, this tendency seems odd. Why should soft hair degrade steel? Until now, the assumption had always been that each shave dulled the blade to the point of it losing its sharp edge.
Now, a curious new study out of MIT finds that this isn't what happens at all. Instead, your hair can crack stainless steel under the right circumstances.
An extremely magnified image of a razor blade cutting hair.
Lead author Gianluca Roscioli grew his facial hair out for three days before shaving. He then brought his razors into the lab to examine them under an electron microscope. While the team expected to see even dulling on the blade edge, they instead noticed strange C-shaped chips missing. Intrigued, they attached a camera to the microscope so they could record the blade cutting the hair. At the same time, they investigated the properties of the razors at the microscopic level.
This apparatus revealed that, when the razor blade hit the hairs at non-perpendicular angles, small cracks formed. These tended to develop in boundary areas between where the steel was harder and where it was softer due to differences in the properties at each location caused by the manufacturing process. Over time, these cracks grew into chips. While these chips are too small to see with the naked eye, they were large enough to reduce the blade's effectiveness.
Roscioli told NPR, "The size of the chips are about 1/10 of the diameter of a human hair."
The chips can be caused by hair of any thickness and appear to be unavoidable in blades with standard imperfections.
The finding surprised other scientists, who also quickly accepted the explanation. Professor Suveen Mathaudhu of UC Riverside explained to NPR that he had expected a larger role in the dulling process to be played by corrosion but that the findings made a great deal of sense. Other scientists expressed how impressed they were by the quality of the images and the difficulty of the study.
How can we possibly use this information?
The study determined that part of the reason for this chipping is the imperfections in the steel used to make the blades, specifically the lack of uniformity in the composition of the steel at the microscopic level. At least partly, these imperfections are due to the nature of the production process and can be reduced through alternative methods. This study's research team is also working on a new material with more structural uniformity as a possible solution.
These findings may one day lead to longer-lasting razor blades. Given that Americans throw out two billion blades each year, such a discovery's environmental impact would be tremendous.
- Anxiety is triggered environmentally and emotionally, but a physiological response quickly follows.
- Calming breathing techniques help to tamp down the physiological response of anxiety.
- The following four exercises are known to help calm anxiety and develop focus.
Stressed? Use This Breathing Technique to Improve Your Attention and Memory, with Emma Seppälä
Alternate Nostril Breathing
Emma Seppälä, science director at Stanford Center For Compassion And Altruism Research And Education, says American culture values intensity yet undervalues calmness. We never shut off. While intensity has its place, every animal in nature inherently knows the necessity of rest in order to store up energy for when it's actually needed. Americans are careless with our energy reserves, which is why so many of us are chronically tired, overworked, and stressed out.
Seppälä knows that breathing changes our state of mind. She recommends a popular yogic breathing technique, nadi shodhana, also known as alternate nostril breathing.
Place the index and middle fingers of your right hand on your forehead. Use your thumb to close your right nostril while inhaling through the left nostril, then close the left nostril with your ring finger and exhale through your right nostril. Repeat this for at least two minutes, then sit quietly for another minute or two, breathing normally.
There are many variations of this technique. My favorite is a four-cycle breath: inhale for a count of four through one nostril, retain your breath for a count of four, exhale for four, hold your breath out for four. If you're new to this breathing technique, retention might initially create more anxiety than it relieves, so try the basic inhale-exhale pattern until you can last for at least five minutes before moving onto breath retentions.
Mind Hack: Combat Anxiety with This Breathing Technique
Game designer and author of "Superbetter," Jane McGonigal, recommends the Power Breath: exhale for twice as long as you inhale. She says this will shift your nervous system from sympathetic to a parasympathetic tone—you'll calm down. Simply sit comfortably, close your eyes, and begin by inhaling for a count of four and exhaling for a count of eight.
This is also a popular yoga breathing technique. As with nadi shodhana, it can initially kick up rather than diminish anxiety. If you find long exhales challenging, begin by inhaling and exhaling at an even rate: a count of four in both directions. Then try to slowly increase your exhale to a count of five, six, and so on. Longtime practitioners can inhale for a count of four and exhale for a count of 50. As with any muscle, you can train your breathing. The benefits are immense.
Breathing Techniques to Help You Relax
Focus Word Breathing
Lolly, a Mind-Body Specialist at the University of Maryland Heart Center, offers what she calls Focus Word Breathing. Traditionally, this is known as Mantra meditation. Choose a word that has meaning to you—calm, grace, ease—and repeat it during every inhalation and exhalation. As your mind wanders, the word becomes a sort of flagpole that you've mentally planted to bring you back to this moment.
As a former sufferer of anxiety disorder, I remember how important my thoughts were when having a panic attack. The power of the physiological symptoms increased when I dwelled on negative thoughts. This spiral felt like being sucked into a vortex. By contrast, when I was able to redirect my thinking, the symptoms lessened.
Mantra meditation never completely worked during an attack. By that point, my physiology had been hijacked. But as a regular practice, this breathing technique is powerful. Think of it as training for the big game of life. You teach yourself to focus on beneficial words. Your attention goes where thinking leads you, but you also have control of your thoughts. By integrating a mantra with breathing, you're priming your mind to focus at will.
How to do Viparita Karani (Legs Up the Wall) w/ AnaMargret Sanchez
Deep Belly Breathing
This exercise is commonly used by yoga instructors to bring their students into Corpse Pose (Savasana). Place your hands over your stomach while lying down and focus your attention there. Take deep, even breaths into your hands. As with the last technique, focus your mind there. Relax the muscles at your extremities: your toes, fingers, and forehead. Allow yourself to melt into the floor.
I love doing this breath while in Viparita Karani, otherwise known as Legs Up the Wall posture. The video above explains how to enter this pose; a blanket or pillow under your lower back makes the posture comfortable. Once there, I practice deep belly breathing. This technique always calms me down. I've recommended it to friends suffering from insomnia; they all responded with positive anecdotal feedback.
