Say a couple wants to have a baby, but they’re infertile. Or they have a weird genetic disease. Or they’re gay. Or they aren’t a couple at all — a single parent just wants to go it alone. Right now, these would-be parents have three options: IVF, adoption, or surrogacy. All three are terrific methods, but they’re also imperfect: inconvenient, expensive, and risky.

Soon these practices may become more obsolete. According to Henry Greely, director of Stanford Law School’s Center for Law and the Biosciences, we’re only 20 years away from couples birthing the babies of their dreams. To do so, women will simply need to give scientists samples of their skin cells. From there, the cells will turn into eggs, then hundreds of embryos — allowing parents to choose which baby they’d prefer to grow in the womb. No sex required.


Greely knows the title of his new book, “The End of Sex and the Future of Human Reproduction” (Harvard University Press, 2016), sounds like science fiction. But he’s confident enough in this new technique — which he calls “Easy PGD” (shorthand for the comically scientific term “easy preimplantation genetic diagnosis”) — that he predicts sexless reproduction will soon become not just a reality, but the cultural norm.

If he’s right, how society conceives of sex, reproductive rights, and the very idea of “family” could be about to change forever. Here, Greely prepares us for the future:

Why is now the time to talk about sexless reproduction?

People have been talking about selecting babies for a long time, but it was always theoretical. Once you can cheaply review all the genetic information and once you can easily and cheaply create eggs, everything changes. Both technologies — cheap genome sequencing and induced pluripotent stem cell — are progressing enormously and attracting lots of money for reasons that have nothing to do with reproduction. When they come together for reproduction, I think they will change our world. They will change our species.

Won’t there be political and cultural resistance?

It will be used first by people who are infertile. There are people absolutely desperate to have genetic children but can’t because of a childhood disease, a birth defect, an accident, cancer, or age. That’s a huge and very politically attractive market. Nobody will want to tell people, “I’m sorry, but we are going to ban the procedure that would let you, who had testicular cancer in your youth, become a genetic father.”

But I think it will spread as more people become confident that it is safe. One to two percent of babies have a serious genetic disease. How much is it worth as a parent to avoid that one- to two-percent risk? If, as I expect in the long run, the process becomes free, then I think we’ll see lots and lots of parents choose this as the way they want to conceive their babies.

You say this will cost nothing to parents. How?

Providing it will save the health care system money. Sick babies are really expensive. Time spent in the neonatal intensive care unit can cost over a million. It will be to the advantage of government-run health care systems as well as private insurers to make Easy PGD free in order to avoid the births of really expensive babies. It will also, of course, be a public health advantage to diminish the amount of human suffering, but I’m not even counting on insurers to care about the amount of human suffering. I do expect them to care about the amount of money.

Is there a right to reproduce in the United States? Where have reproductive technologies transformed into rights?

In much of the world, IVF has changed from a new technology into a right. Denmark has a very high IVF rate. Israel has a high rate. [In those countries], it was covered by national health insurance and became a right, but at the same time, they limit it. In France, IVF is covered by the national health care system, but you can only use it if you are a heterosexual couple in an established relationship. In Italy, you can’t use it if you’re a woman over a certain age. In the United Kingdom, you can’t use a PGD for anything other than specific diseases permitted by a government agency.

On the other hand, IVF is almost completely uncovered by insurance in the United States. There’s a basic, important distinction in our constitutional law: the difference between a positive right and a negative right. A negative right is a right to have the government not interfere with you. We don’t view fertility as a positive right — as something the government will pay you to do or guarantee for you — but we’ve been almost entirely hands-off in preventing it.

[quote position=”full” is_quote=”true”]That’s a dangerous path for the government, to say some lives are worth living and some aren’t.[/quote]

What impact will this have on people with disabilities?

First, most disabilities are not the result of genetics. They’re the result of infectious diseases or accidents. There will always be people in wheelchairs, even if we were to eliminate the genetic causes of being in a wheelchair. Having said that, to me intellectually and emotionally, the disability contexts for this are the hardest. I remember at a conference I put on about PGD, one of the panelists had spinal muscular atrophy, so she was confined to a wheelchair. She was in her late 20s, a very bright woman, a Stanford graduate, and she basically said, “What you are saying is that I shouldn’t have been born.”

I surely didn’t want to say that. I said, “No, I’m saying your parents in the future would have a choice about whether you were born with a disease.” She said, quite accurately, “Me without a disease is not me.” And that’s right. There’s a very real psychologically stigmatic and symbolic effect that a technology like this will have on people with disabilities. Then there are very concrete potential effects. Let’s say Down syndrome becomes much less common. What does that do for research into Down syndrome? What does that do for social support?

These questions, for me, are the very hardest. Ultimately it is true that from disability and from suffering, wonderful things can come, but we can’t guarantee that wonderful things will come from suffering. What we can guarantee will come from suffering is suffering.

Maybe if we eliminated genes that lead to people with manic-depressive disorder, we would have lost Vincent Van Gogh, but then maybe he wouldn’t have committed suicide as a young man. And for every manic-depressive who is a Van Gogh, there are hundreds of thousands whose suffering is not redeemed by genius or experience.

This technology sounds like a eugenicist’s dream. Will it be used as a coercive tool?

I don’t have nightmares. I don’t think we’re going to require everybody to use this and to only transfer embryos [whose genes] predict above-average intelligence. Outside the U.S., I could see that happening — not in a lot of countries, but in some. But in the U.S., I can see us doing coercive things that might be borderline. I could see a state passing a law saying you can use this to detect really serious early-onset diseases but not other diseases. I think that’s a dangerous path for the government, to say some lives are worth living and some aren’t.

I don’t think coercion is always a bad idea. I’m in favor of the IRS, or at least taxation, which is coercive. But when it comes to picking the traits of my kids, my strong preference is to let the parents decide. They’re the ones who are going to have to live with the best decision and who are most likely to have the kid’s best interests at heart.

If you were in a position 20 years from now to start a family with Easy PGD as an option, how would you decide whether to use it?

First, I would talk very seriously to the person with whom I was trying to make a baby. When my wife was pregnant with our first child, she got a prenatal diagnosis to find out whether the fetus would turn into a baby with Down syndrome. I was unsure whether I wanted to know that, but she was the one who was pregnant. It’s a negotiation. I suspect our ability to influence a future child’s behavior will be pretty weak, so I would ignore that. “Oh, this embryo has a 53 percent chance of being in the top half of math ability.” That’s noise.

    Putting The ‘5-4-3-2-1 Packing Method’ Into Action

    In her trending TikTok post, Lumbatis shares a packing system she claims to be “as easy as it sounds.” Here are the basics of the 5-4-3-2-1 packing method:

    • 5 TOPS
    • 4 BOTTOMS
    • 3 SHOES
    • 2 LAYERS
    • 1 MISCELLANEOUS

    Lumbatis explains, “So all you got to do is pick out 5 tops, 4 coordinating bottoms, 3 pairs of shoes, 2 layering pieces, and 1 of anything else. Like a dress, pajamas, a hat, a belt, or any other accessories that you might need. And then of course pack as many undergarments and toiletries as you need.”

    The strategy isn’t just about simplifying and maximizing the number of items you bring on a trip. It’s also about function. “The key is to pick versatile pieces that can mix and match so you can pair them up for whatever activities you have planned for your trip.”

    Taking Pictures Can Help Plan Ahead

    Another helpful step is taking photos of your outfits to remember how everything fits together. Lumbatis offers, “You can even take pictures of the outfits with you wearing them or flat lays of the pieces and keep them on your phone or in your Notes App — So you can refer back to it on your trip.”

    Is the 5-4-3-2-1 packing method effective? These were some of the thoughts in the comments from readers hopeful to put the plan into action:

    “Great tip for me. Hate packing and never wear all the clothes I bring.”

    “Heading to Japan and I was just going to my closet to put it together. I overpack so this is sooo helpful.”

    “I’m dreading how to not over pack for such a variety of occasions, heat, and limited washing facilities. Ugh.”

    “I struggle with under packing so this is super helpful!”

    The Science Behind Good Preparation

    Traveling is a great way to alleviate the stress and burdens of our daily lives. A 2025 study in Springer Nature Link showed travel helped people improve their long-term resilience by creating positive emotions while ecouraging self reflection. National Geographic found the benefits of travel begin even before the trip begins.

    However, preparation can have a powerful effect on the simple stresses a person might acquire during traveling. A 2025 study revealed that planning reduced anxiety and helped people prepare for delays or unexpected changes. Research in 2025 reported by AP News found that even making a simple checklist reduced anxiety and helped make for smoother trips.

    Lumbatis claims, “If you struggle with overpacking and want to create a great capsule wardrobe packing list, you’ve got to try this method.”

    People hope that traveling will relieve stress more than generate it. The 5-4-3-2-1 packing method offers a clear and simple way to pack just what you need. Careful preparation helps prevent last-minute chaos and produces a more enjoyable trip. Hopefully, this method can help you spend less time worrying and more time soaking in the adventure.

  • People are cheering woman’s refusal to accept the latest trend in hotel bathrooms
    Sadie has declared war on non-private hotel bathrooms.Photo credit: @bring_back_doors

    People are cheering woman’s refusal to accept the latest trend in hotel bathrooms

    “I HATE how hotels started thinking going to the bathroom is a shared experience.”

    It can be frustrating seeing change for change’s sake in the world. To be more specific, changes that are said to be done in the name of innovation and design, but are in truth ways for companies to save a buck.

    One example that is getting attention is the bathroom doors in hotels… or the lack thereof, actually. One TikToker has had enough and has taken it upon herself to save regular bathroom doors in hotels and to point out why open-space bathrooms and glass doors just don’t cut it.

    On her @bring_back_doors TikTok account, Sadie has a collection of videos highlighting the flaws in hotel bathroom designs, with the most prominent being the lack of a regular door to the bathroom. In one viral TikTok, Sadie discussed a hotel that reached out to her, explaining that they have “foggy” glass doors to their bathroom to provide privacy. She was quick to point out that it still doesn’t provide adequate privacy. “Yes you can see through these,” Sadie said, adding that “glass doors do not close properly.”


    @bring_back_doors

    Hotel name: Alexander Hotel, Noordwijk aan Zee, Netherlands I need to be clear. Glass doors are not private. And making them foggy does not make them private. I am once again sitting here saying screw you to all bathroom doors that are not solid and close fully. And I am providing alternative hotels with guaranteed doors at bringbackdoors.com Check your hotels door situation before you book or risk your privacy. Door submitted by @mmargaridahb, DM me to submit your own bad doors. #bathroomdoors #hotel #travel #fyp Bathroom doors | bathroom design | hotel design | bad hotel design | travel fail | travel memories | travel inspo | door design | hotels with privacy

    The comments rallied behind Sadie’s bathroom-door crusade

    The commenters joined in with Sadie, demanding the return of solid, closing, and lockable doors to bathrooms in hotels:

    “I HATE how hotels started thinking going to the bathroom is a shared experience.”

    “I hate how you can’t turn the bathroom light on without disturbing the other person in the room.”

    “The foggy ones are almost worse, you just get a hazy fleshy silhouette hunched over on the crapper like some kind of sack of ham.”

    “I just don’t get it, NOBODY wants this, even couples. I won’t be more likely to book two separate rooms for me and my friend/sibling/parent, I’ll just book another hotel.”

    “Love this campaign, I do not want a romantic weekend listening to the other person poo.”

    Hotel Names⬇️⬇️ Citizen M South Hotel (first pics) and Fletcher Hotel (third pic) both in Amsterdam. As part of this project, I’ve been emailing hotels around the world to put together an easy to reference list for people to find hotels with guaranteed doors at BringBackDoors.com And I did notice that in Amsterdam a lot of hotels were saying they don’t have doors. It wasn’t the worst city (that honor goes to Barcelona, so far I’ve only found TWO that have said yes to all doors), but it was still bad. Then I went into the comments. And kept getting people mentioning these hotels in Amsterdam. And I realized that clearly the city has a designer or architect on the loose who has a thing for test tubes. It’s horrible. Luckily, I was able to find 6 hotels in Amsterdam that all have bathroom doors in every room and have them all listed on BringBackDoors.com These hotels were submitted by so many people I couldn’t name them all. But to submit your own bad hotel bathroom send me a DM with hotel photo, name, and location! #hotel #bathroom #hoteldesignfail Bathroom doors | hotel bathrooms | hotel privacy | no privacy | travel problems | hotel issues | travel | hotel design | hotel design fail | hotel designers | design fail | hotel concept | bathrooms | Citizen M | Hotel Fletcher | Hotels in Amsterdam | Visit Amsterdam | Amsterdam

    A great way to save a buck—er, I mean, ‘create a modern look’

    As many commenters asked, why do hotels have glass doors — or, worse, no doors at all—in their bathrooms? Well, this has been a growing trend in modern hotels over the past decade as a means to create a sleek aesthetic and to allow glass partitions to bring more daylight into otherwise darker sections of the room.

    At least that’s what’s being promoted to the customer. In reality, skimping on solid doors for glass ones or none at all gives the illusion that the room is bigger than it is while requiring fewer building materials. It does bring in more daylight, but mostly with the hope that you’ll cut down on electricity use for lights in an otherwise enclosed space. These reasons are also why some hotels don’t have solid walls around their bathroom areas at all.

    Tired of the lack of privacy? Check out the database

    To combat this trend, Sadie has developed a database at bringbackdoors.com for her and her followers to report which hotels have true, solid, private bathrooms in their accommodations and which ones do not, so people can properly plan where to stay and have true privacy during their most vulnerable moments.

    “I get it, you can save on material costs and make the room feel bigger, but what about my dignity?,” Sadie wrote on her website. “I can’t save that, when you don’t include a bathroom door.”

    Over time, the hope is that sanity and dignity can be restored as hotels realize that their glass “features” don’t have any real benefit when they don’t allow basic privacy.

    MIT’s super-fast camera can capture light as it travels

    It has a resolution rate of one frame per trillionth of a second.

    A camera developed at MIT can photograph a trillion frames per second. Compare that with a traditional movie camera which takes a mere 24. This new advancement in photographic technology has given scientists the ability to photograph the movement of the fastest thing in the Universe, light. In the video below, you’ll see experimental footage of light photons traveling 600-million-miles-per-hour through water.

    The actual event occurred in a nano second, but the camera has the ability to slow it down to twenty seconds. For some perspective, according to New York Times writer, John Markoff, “If a bullet were tracked in the same fashion moving through the same fluid, the resulting movie would last three years.”


    It’s impossible to directly record light so the camera takes millions of scans to recreate each image. The process has been called femto-photography and according to Andrea Velten, a researcher involved with the project, “There’s nothing in the universe that looks fast to this camera.”
