The TV was on as we sat waiting to be called in for our check up. My son, who is 11, turned his head as he heard the anchor use the word “EpiPen”. He is in tune since he has a life threatening peanut allergy and the EpiPen has saved his life. His face was full of emotion as he listened to the anchor talk about how some people could no longer afford this life saving device. He shook his head and said “mom that can't be right, they can't be right, can they, everyone who needs an EpiPen should have one.”
The media has exploded as word spread of some parents paying well over 600 dollars for this necessary life saving device. Headlines abound about big pharmacy greed and patients forced to pay outrageous prices, and this issue has enraged everyone. I am heartened to see food allergies being taken seriously in the mainstream media. As my son stated, everyone who needs an Epipen should have access to one. But food allergies are a topic that is underreported. Even when we are armed with our EpiPens, we have a long way to go in getting the public to recognize the real challenges of living in a world where respect for food allergies as a potential life threatening disease is lacking.
As founder of the No Nut Traveler, I collect the testimonials of food allergic passengers traveling on commercial airlines. Shockingly, many food allergic passengers are being ridiculed, spoken to rudely by the airline staff and most egregiously, sometimes asked to leave the airplane when disclosing a food allergy.
Last month, a food allergy mom sent me a testimonial via FaceBook with a heart-breaking photo of her child, as her family was asked to leave the plane by the pilot for disclosing her child's food allergy. She informed me that she had notified the airline ahead of time of her daughter's allergies. She brought their own food and a supply of medication. She said “We did everything humanly possible on our part. I do not know what else we could have done to prevent such a situation from happening”. She went on to tell me “a supervisor from JFK was called on board and he took our passports and boarding passes. We were then escorted out of the plane under the threat of calling security on us. We were publicly humiliated as we walked through the full airplane. My daughter was brought to tears. On the same airline the next day, a different pilot let our family fly. I find this kind of inconsistency and rudeness unacceptable.
Later in the month, a 22-year-old girl from New Jersey shared another disturbing encounter with me. She asserted that after asking for an announcement for her severe nut allergy, and asking for the surrounding rows to please refrain from eating nuts, the pilot told her that she was an inconvenience to have on-board, and that her thought process was selfish. She further asserted that the pilot said to her “You should be thankful to be allowed on this flight due to the huge risk and inconvenience you may cause to other passengers”. Her aunt, who was traveling with her, then asked what they would do if they had someone with a disability on the airplane and the pilot said they would accommodate them. She then asked why not her niece and he responded because a food allergy is not a disability.
When you receive the diagnosis of a life threatening food allergy, your life is irrevocably altered. Failure to treat a food-induced anaphylaxis quickly (i.e. within minutes) with epinephrine substantially increases the risk of death. No one asks to have this condition. There is the false perception that once you have your EpiPen, everything will be fine. But the truth is that sometimes the EpiPen can only buy you time. That is one of the reasons why you need to carry more than one-a reaction can require multiple EpiPens, and you always need to go to the ER to be monitored after using one.
There is no ER in the air and that is why, as allergic passengers, we ask for reasonable accommodations to make flying safer. Being able to pre-board, to clean the area from the last occupant, informing those around us to be cautious and asking politely not to consume what is deadly to us, and educating the airline staff of this potentially fatal disability, are reasonable requests for a legitimate medical condition. My greatest fear is that it will take a death in the air for meaningful change to occur.

Walker & Co. Founder and CEO, Tristan Walker didn't always see himself trying to build a health and beauty products company. In fact, he tried to cure childhood obesity, start a bank, and build a freight truck fixing company first, which were very big, very complicated ventures he knew little about before he created Bevel, that directly related to a familiar problem. However, when it came time for investments, he received more “no's” than he thought possible, but managed to push himself even harder. “I knew it wasn't a bad idea because I felt no one could work this thing better than we could,” Walker says.
In this interview, Walker takes us through the journey of starting his company, shares how he overcame his toughest trials, and why hiring the same kind of people may even be a good thing.
Walker is Founder and CEO of Walker & Co. Brands, a company that makes health and beauty simple for people of color. Its flagship brand, Bevel, is the first and only shaving system clinically proven to reduce and prevent razor bumps and irritation. Tristan is also the Founder and Chairman of CODE2040, a program that matches high performing black and latino undergraduate and graduate coders and software engineering students with Silicon Valley start-ups for summer internships.

Writer-illustrator Shaun Tan turned sculptor for his new book, The Singing Bones, which collects images of the 75 miniature tableaux he made of the Brothers Grimm's immortal collection of dark, disturbing fairytales
Continue reading...The writer-illustrator made his name with dark, unsettling picture books such as The Rabbits. Now he's swapped his pencil for clay to make miniature nightmares based on the stories of the Brothers Grimm
Two centuries and a world apart, the Brothers Grimm and Shaun Tan share an ability to confound those who attempt to categorise them. When the German Grimm siblings released the first edition of their tales in 1812, it was under the name Kinder-und Hausmärchen, or Children's and Household Tales, a title that belied the incest, infanticide and cannibalism found within. It didn't sell. Even after they spent 45 years making increasingly child-friendly revisions over seven editions, their tales of princesses and princes, step-mothers and witches remained controversial; after the second world war, allied forces briefly banned the publication of the Grimm tales in Germany, believing that their violence and nationalism had fuelled Nazi savagery, while around the same time, Disney was hijacking them for saccharine retellings of Cinderella (featuring less eye-plucking) and Snow White (less death by dancing).
Tan also ostensibly writes books for children, but has a history of confusing adults with his surreal, often political picture books. The Australian artist quickly became famous for his intricately illustrated and laconic stories. He picked at the scabs of Australian history in books including The Rabbits (1998), a surreal allegory about colonisation, and The Arrival (2006), an entirely wordless graphic novel about refugees, and he pulled apart mental illness and depression in picture book The Red Tree (2001). Tan was dismissed by some on Australia's right for producing “politically correct propaganda”; for those who loved him, the greatest criticism could be that his books “would almost rather be looked at than read”, as the New York Times once wrote.

A lost Nasa spacecraft “phoned home” after 22 months of silence this week. Stereo-B (Solar Terrestrial Relations Observatory) is a twin to Stereo-A, and together they have been studying the Sun since 2006.
Although planned to last just two years, the mission had been working so well that ground controllers and scientists kept the spacecraft going. The data returned has given unprecedented insights into solar storms, which can threaten the electrical systems of satellites around Earth.

Within the penumbra, the eclipse is partial (left), but within the umbra, the Moon completely covers the Sun (right).
“Red dwarfs the dim bulbs of the cosmos have received scant attention by SETI scientists in the past,” said Jon Richard, of SETI, a private, non-profit organization which stands for Search for Extraterrestrial Intelligence. “That's because researchers made the seemingly reasonable assumption that other intelligent species would be on planets orbiting stars similar to the sun.”
Yesterday's announcement that astronomers using European Southern Observatory (ESO) telescopes in Chile shown above and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri may ultimately prove to be a habitable planet could that harbor an advanced technological civilization. The long-sought world, designated Proxima b, orbits its cool red -dwarf parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than the Earth and is the closest exoplanet to us -- and it may also be the closest possible abode for life outside the Solar System.
Red Dwarfs “may be one instance in which older is better,” said Seth Shostak, senior astronomer and director of California-based SETI. “Older solar systems have had more time to produce intelligent species.” A super-Earth known as Kapteyn b that orbits an 11.5 billion-year-old red dwarf, for example, makes the star and the planet 2.5 times older than Earth.
The SETI Institute belives that planetary systems orbiting red dwarfs — dim, long-lived stars that are on average billions of years older than our sun — are worth investigating for signs of advanced extraterrestrial life. The star that's closest to our sun, Proxima Centauri, is a red dwarf. A variety of observing efforts, including Cornell's Pale Red Dot initiative, are looking for habitable planets around Proxima Centauri .
The two-year project involves picking from a list of about 70,000 red dwarfs and scanning 20,000 of the nearest ones, along with the cosmic bodies that circle them using the SETI Institute's Allen Telescope Array in the High Sierras of northern California, a group of 42 antennas that can observe three stars simultaneously.
“We'll scrutinize targeted systems over several frequency bands between 1 and 10 GHz,” said SETI scientist Gerry Harp. “Roughly half of those bands will be at so-called ‘magic frequencies' — places on the radio dial that are directly related to basic mathematical constants. It's reasonable to speculate that extraterrestrials trying to attract attention might generate signals at such special frequencies.”
For a long time, scientists ruled out searching around red dwarfs because habitable zones around the stars are small, and planets orbiting them would be so close that one side would be constantly facing the star, making one side of the planet very hot and the other quite cold and dark. But more recently, scientists have learned that heat could be transported from the light side of the planet to the darker side, and that much of the surface could be amenable to life.
“In addition, exoplanet data have suggested that somewhere between one sixth and one half of red dwarf stars have planets in their habitable zones, a percentage comparable to, and possibly greater than, for Sun-like stars,” said the statement.
The brightest of Red Dwarfs are a tenth as luminous as the sun, and some are just 0.01 percent as bright, but account for three-quarters of all stars, with 6 percent or more of all red dwarfs having potentially habitable, Earth-sized planets.
Guillem Anglada-Escudé from Queen Mary University of London who led the Pale Red Dot project explains the background to this unique search: "The first hints of a possible planet were spotted back in 2013, but the detection was not convincing. Since then we have worked hard to get further observations off the ground with help from ESO and others. The recent Pale Red Dot campaign has been about two years in the planning."
During the first half of 2016 Proxima Centauri was regularly observed with the HARPS spectrograph on the ESO 3.6-metre telescope at La Silla in Chile and simultaneously monitored by other telescopes around the world. This was the Pale Red Dot campaign that was looking for the tiny back and forth wobble of the star that would be caused by the gravitational pull of a possible orbiting planet.
The Pale Red Dot data, when combined with earlier observations made at ESO observatories and elsewhere, revealed the clear signal of a truly exciting result. At times Proxima Centauri is approaching Earth at about 5 kilometers per hour -- normal human walking pace -- and at times receding at the same speed. This regular pattern of changing radial velocities repeats with a period of 11.2 days. Careful analysis of the resulting tiny Doppler shifts showed that they indicated the presence of a planet with a mass at least 1.3 times that of the Earth, orbiting about 7 million kilometers from Proxima Centauri -- only 5% of the Earth-Sun distance.
Guillem Anglada-Escudé comments on the excitement of the last few months: "I kept checking the consistency of the signal every single day during the 60 nights of the Pale Red Dot campaign. The first 10 were promising, the first 20 were consistent with expectations, and at 30 days the result was pretty much definitive, so we started drafting the paper!"
Red dwarfs like Proxima Centauri are active stars and can vary in ways that would mimic the presence of a planet. To exclude this possibility the team also monitored the changing brightness of the star very carefully during the campaign using the ASH2 telescope at the San Pedro de Atacama Celestial Explorations Observatory in Chile and the Las Cumbres Observatory telescope network. Radial velocity data taken when the star was flaring were excluded from the final analysis.
Although Proxima b orbits much closer to its star than Mercury does to the Sun in the Solar System, the star itself is far fainter than the Sun. As a result Proxima b lies well within the habitable zone around the star and has an estimated surface temperature that would allow the presence of liquid water. Despite the temperate orbit of Proxima b, the conditions on the surface may be strongly affected by the ultraviolet and X-ray flares from the star -- far more intense than the Earth experiences from the Sun [4].
Two separate papers discuss the habitability of Proxima b and its climate. They find that the existence of liquid water on the planet today cannot be ruled out and, in such case, it may be present over the surface of the planet only in the sunniest regions, either in an area in the hemisphere of the planet facing the star (synchronous rotation) or in a tropical belt (3:2 resonance rotation). Proxima b's rotation, the strong radiation from its star and the formation history of the planet makes its climate quite different from that of the Earth, and it is unlikely that Proxima b has seasons.
This discovery will be the beginning of extensive further observations, both with current instruments and with the next generation of giant telescopes such as the European Extremely Large Telescope (E-ELT). Proxima b will be a prime target for the hunt for evidence of life elsewhere in the Universe. Indeed, the Alpha Centauri system is also the target of humankind's first attempt to travel to another star system, the StarShot project.
Guillem Anglada-Escudé concludes: "Many exoplanets have been found and many more will be found, but searching for the closest potential Earth-analogue and succeeding has been the experience of a lifetime for all of us. Many people's stories and efforts have converged on this discovery. The result is also a tribute to all of them. The search for life on Proxima b comes next..."

"The echoing of FRBs is a very direct probe of dark matter," Munoz said. "While gravitational waves might 'indicate' that dark matter is made of black holes, there are other ways to produce very-massive black holes with regular astrophysics, so it would be hard to convince oneself that we are detecting dark matter. However, gravitational lensing of fast radio bursts has a very unique signature, with no other astrophysical phenomenon that could reproduce it."
Astrophysicists from the Johns Hopkins University have proposed a clever new way of shedding light on the mystery of dark matter, believed to make up most of the universe. The irony is they want to try to pin down the nature of this unexplained phenomenon by using another, an obscure cosmic emanation known as "fast radio bursts."In a paper published online by the journal Physical Review Letters the team of astrophysicists argues that these extremely bright and brief flashes of radio-frequency radiation can provide clues about whether a particular kind of ancient black hole is what makes up dark matter.
Julian Munoz, a Johns Hopkins graduate student and the paper's lead author, said fast radio bursts, or FRBs, provide a direct and specific way of detecting black holes of a specific mass, which are the suspect dark matter.
Munoz wrote the paper along with Ely D. Kovetz a post-doctoral fellow, Marc Kamionkowski, the William R. Kenan Jr. Professor of Physics and Astronomy, and Liang Dai, who completed his doctorate in astrophysics at Johns Hopkins last year. Dai is now a NASA Einstein Postdoctoral Fellow at the Institute for Advanced Study in Princeton.
The paper builds on a hypothesis offered in a paper published this spring by Munoz, Kovetz and Kamionkowski along with five Johns Hopkins colleagues. Also published in Physical Review Letters, that research made a speculative case that the collision of black holes detected early in the year by the Laser Interferometer Gravitational-Wave Observatory (LIGO) had actually revealed dark matter, a substance not yet identified but believed to make up 85 percent of the mass of the universe.
The earlier paper made what Kamionkowski called a "plausibility argument" that LIGO had found dark matter. The study took as a point of departure the fact that the objects detected by LIGO fit within the predicted range of mass of so-called "primordial" black holes. Unlike black holes that formed from imploded stars, primordial black holes are believed to have formed from the collapse of large expanses of gas during the birth of the universe.
The existence of primordial black holes has not been established with certainty, but they have been suggested before as a possible solution to the riddle of dark matter. With so little evidence of them to examine, the hypothesis had not gained a large following among scientists.
The LIGO findings, however, raised the prospect anew, especially as the objects detected in that experiment conform to the mass predicted for dark matter.
The Johns Hopkins team calculated how often these primordial black holes would form binary pairs, and eventually collide. Taking into account the size and elongated shape believed to characterize primordial black hole binary orbits, the team came up with a collision rate that conforms to the LIGO findings.
Key to the argument is that the black holes that LIGO detected fall within a range of 29 to 36 solar masses, meaning that many times the mass of the sun. The new paper considers the question of how to test the hypothesis that dark matter consists of black holes of roughly 30 solar masses.
That's where the fast radio bursts come in. First observed only a few years ago, these flashes of radio frequency radiation emit intense energy, but last only fractions of a second. Their origins are unknown, but believed to lie in galaxies outside the Milky Way.
If the speculation about their origins is true, Kamionkowski said, the radio waves would travel great distances before they're observed on Earth, perhaps passing a black hole. According to Einstein's theory of general relativity, the wave would be deflected when it passes a black hole. If it passes close enough, it could be split into two rays shooting off in the same direction - creating two images from one source.
The new study shows that if the black hole has 30 times the mass of the sun, the two images will arrive a few milliseconds apart. If roughly 30-solar-mass primordial black holes are dark matter, there is a chance that any given fast radio burst will be deflected in this way and followed in a few milliseconds by an echo.
Kaimonkowski said that while the probability for any such FRB echo is small, "it is expected that several of the thousands of FRBs to be detected in the next few years will have such echoes ... if black holes make up the dark matter."
So far, only about 20 fast radio bursts have been detected and recorded since 2001. The very sensitive instruments needed to detect them can look at only very small slices of the sky at a time, limiting the rate at which the bursts can be found. A new telescope expected to go into operation this year that seems particularly promising for spotting radio bursts is the Canadian Hydrogen Intensity Mapping Experiment. The joint project of the University of British Columbia, McGill University, the University of Toronto and the Dominion Radio Astrophysical Observatory stands in British Columbia.
"Once the thing is working up to their planned specifications, they should collect enough FRBs to begin the tests we propose," said Kamionkowski, estimating results could be available in three to five years.
The image at the top of the page shows he 305-m Arecibo telescope. From space, a sequence of millisecond-duration radio flashes are racing towards the dish, where they will be reflected and detected by the radio receivers. Such radio signals are called fast radio bursts, and Arecibo is the first telescope to see repeat bursts from the same source. (Danielle Futselaar).

The standard ways of thinking about morality don't apply well to parenthood
Why is taking care of children worthwhile? It's hard work, badly paid if paid at all, and full of uncertainty, guilt and heavy lifting. And yet, at least to most of us, it seems like an absolutely fundamental, profoundly valuable project. If you asked most parents about their deepest moral commitments, and most agonising moral dilemmas, about what gives their lives meaning, they would talk about their children. But caring for a child is very different from any other human relationship, and the standard ways of thinking about morality and meaning don't apply very well to being a parent.
Caring for children is deeply paradoxical. There's a profound tension between dependence and independence. Parents and other caregivers must take complete responsibility for that most utterly dependent of creatures, the human baby. But they must also transform that utterly dependent creature into a completely independent and autonomous adult. We start out feeding and changing and physically holding our children most of the day, and doing all this with surprising satisfaction and even happiness. We end up, if we're lucky, with the occasional affectionate text message from a distant city. A marriage or friendship that was like that would be peculiar, if not downright pathological.

The edge of Queens Wood in north London. It's just a ten minute walk from my home. When I'm suffering from PWS* it's good to be close to a place that I can explore at the drop of a hat. Living so close to the centre of town it's something I'm very fortunate to have.
Thanks for looking.

An international team of astronomers has found clear evidence of a planet orbiting Proxima Centauri. The new world, designated Proxima b, orbits its parent star every 11 days and has a temperature suitable for liquid water to exist on its surface, if it were present. This artist's impression shows a view of the surface of the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to the solar system. The double star Alpha Centauri AB also appears in the image to the upper-right of Proxima b itself. Proxima b is a little more massive than the Earth and orbits in the habitable zone around Proxima Centauri, where the temperature is suitable for liquid water to exist on its surface.

A team of Harvard University researchers with expertise in 3-D printing, mechanical engineering, and microfluidics has demonstrated the first autonomous, untethered, entirely soft robot. This small, 3-D-printed robot -- nicknamed the octobot -- could pave the way for a new generation of completely soft, autonomous machines. Soft robotics could revolutionize how humans interact with machines. But researchers have struggled to build entirely compliant robots. Electric power and control systems -- such as batteries and circuit boards -- are rigid and until now, soft-bodied robots have been either tethered to an off-board system or rigged with hard components.
