New therapy cures cancer with just one injection
It neutralized not only the tumor it was injected into but malignancies all over the body.

Current cancer therapies have terrible side effects and aren’t always effective. And with things like radiotherapy and chemotherapy, the number of treatments one needs to endure makes side effects progressively worse over time. A new technique developed by researchers at Stanford University uses two agents which when combined, alert the body’s immune system to the presence of cancer, in order to eliminate it.
Just one injection can be effective for a solid tumor. Such a targeted approach could limit nasty side effects and may even be more effective than current therapies. These results were published in the journal Science Translational Medicine. Dr. Ronald Levy was the study’s senior author. He told Medical News Daily, "When we use these two agents together, we see the elimination of tumors all over the body."
Dr. Levy and colleagues injected minute levels of two “immune-stimulating agents,” into malignant solid tumors in mice. The most remarkable thing is that it treated not only the tumor it was injected into, but distant malignancies at other locations inside the body. Researchers believe it’ll be able to treat all different kinds of cancer. Using T-cells to kill cancer has long been a driving focus of immunotherapy.
Although T-cells already have incredibly powerful cancer-fighting properties, cancer cells have certain “tricks” to circumvent them, until they’ve multiplied enough to overwhelm the immune system entirely. Immunotherapy seeks to boost the immune systems capabilities, in order for it to recognize the cancer and neutralize it.

Clinical trials are currently underway, to see if the same effect occurs in humans. 15 patients, all with low-grade lymphoma, are taking part. Those with this particular type of cancer were selected because lymphoma is essentially a disease of the immune system and so, should show the strongest response to the therapy.
One of the agents has already gained FDA approval, while the other is part of an ongoing clinical trial as a treatment for lymphoma. This has helped streamline the process a bit. What’s also exciting is, in addition to being effective, the agents are inexpensive. “This method can ‘teach’ immune cells how to fight against that specific type of cancer,” Dr. Levy said, “which then allows them to migrate and destroy all other existing tumors.”
There are several different immunotherapy approaches in use today. Some activate the immune system everywhere in the body. Others remove the patient’s own immune cells and genetically engineer them to kill cancer. And others still turn off switches in immune cells which limit their cancer fighting abilities.
The drawbacks are that many of these experimental therapies are expensive or time consuming, or cause terrible side effects. According to Dr. Levy, “This approach bypasses the need to identify tumor-specific immune targets and doesn’t require wholesale activation of the immune system or customization of a patient’s immune cells.” The dual injection includes just one microgram (one-millionth of a gram) of each substance.

The makeup of the injection includes a short, synthetic piece of DNA called CpG oligonucleotide. This binds to the receptor OX40, found on the surface of T-cells. The other is an antibody which binds to a T-cell and activates it. Once they make short work of the tumor, these energized T-cells travel elsewhere throughout the body, eliminating all of the same kind of cancer cells.
To test out the treatment, researchers injected 90 mice who had lymphoma with the mixture. 87 out of 90 became completely cancer-free. When tumors did recur in the remaining three, a second injection eliminated them completely, with no further recurrence. Mouse models with breast, skin, and colon cancer showed similar results.
One stipulation, the T-cells can only target the type of cancer they first experienced. Mouse models that had lymphoma and colon cancer saw only the lymphoma eliminated. The T-cells get trained to take out a particular type of cancer, and that’s what they focus on.
Should this therapy be successful in humans, Dr. Levy and colleagues foresee it being injected after the surgical removal of a solid tumor, to make sure the cancer doesn’t recur. It might even take out any budding tumors that occur due to a genetic mutation. Dr. Levy said there’s no cancer it couldn’t treat, just so long as the immune system can infiltrate it.

‘Designer baby’ book trilogy explores the moral dilemmas humans may soon create
How would the ability to genetically customize children change society? Sci-fi author Eugene Clark explores the future on our horizon in Volume I of the "Genetic Pressure" series.
- A new sci-fi book series called "Genetic Pressure" explores the scientific and moral implications of a world with a burgeoning designer baby industry.
- It's currently illegal to implant genetically edited human embryos in most nations, but designer babies may someday become widespread.
- While gene-editing technology could help humans eliminate genetic diseases, some in the scientific community fear it may also usher in a new era of eugenics.
Tribalism and discrimination
<p>One question the "Genetic Pressure" series explores: What would tribalism and discrimination look like in a world with designer babies? As designer babies grow up, they could be noticeably different from other people, potentially being smarter, more attractive and healthier. This could breed resentment between the groups—as it does in the series.</p><p>"[Designer babies] slowly find that 'everyone else,' and even their own parents, becomes less and less tolerable," author Eugene Clark told Big Think. "Meanwhile, everyone else slowly feels threatened by the designer babies."</p><p>For example, one character in the series who was born a designer baby faces discrimination and harassment from "normal people"—they call her "soulless" and say she was "made in a factory," a "consumer product." </p><p>Would such divisions emerge in the real world? The answer may depend on who's able to afford designer baby services. If it's only the ultra-wealthy, then it's easy to imagine how being a designer baby could be seen by society as a kind of hyper-privilege, which designer babies would have to reckon with. </p><p>Even if people from all socioeconomic backgrounds can someday afford designer babies, people born designer babies may struggle with tough existential questions: Can they ever take full credit for things they achieve, or were they born with an unfair advantage? To what extent should they spend their lives helping the less fortunate? </p>Sexuality dilemmas
<p>Sexuality presents another set of thorny questions. If a designer baby industry someday allows people to optimize humans for attractiveness, designer babies could grow up to find themselves surrounded by ultra-attractive people. That may not sound like a big problem.</p><p>But consider that, if designer babies someday become the standard way to have children, there'd necessarily be a years-long gap in which only some people are having designer babies. Meanwhile, the rest of society would be having children the old-fashioned way. So, in terms of attractiveness, society could see increasingly apparent disparities in physical appearances between the two groups. "Normal people" could begin to seem increasingly ugly.</p><p>But ultra-attractive people who were born designer babies could face problems, too. One could be the loss of body image. </p><p>When designer babies grow up in the "Genetic Pressure" series, men look like all the other men, and women look like all the other women. This homogeneity of physical appearance occurs because parents of designer babies start following trends, all choosing similar traits for their children: tall, athletic build, olive skin, etc. </p><p>Sure, facial traits remain relatively unique, but everyone's more or less equally attractive. And this causes strange changes to sexual preferences.</p><p>"In a society of sexual equals, they start looking for other differentiators," he said, noting that violet-colored eyes become a rare trait that genetically engineered humans find especially attractive in the series.</p><p>But what about sexual relationships between genetically engineered humans and "normal" people? In the "Genetic Pressure" series, many "normal" people want to have kids with (or at least have sex with) genetically engineered humans. But a minority of engineered humans oppose breeding with "normal" people, and this leads to an ideology that considers engineered humans to be racially supreme. </p>Regulating designer babies
<p>On a policy level, there are many open questions about how governments might legislate a world with designer babies. But it's not totally new territory, considering the West's dark history of eugenics experiments.</p><p>In the 20th century, the U.S. conducted multiple eugenics programs, including immigration restrictions based on genetic inferiority and forced sterilizations. In 1927, for example, the Supreme Court ruled that forcibly sterilizing the mentally handicapped didn't violate the Constitution. Supreme Court Justice Oliver Wendall Holmes wrote, "… three generations of imbeciles are enough." </p><p>After the Holocaust, eugenics programs became increasingly taboo and regulated in the U.S. (though some states continued forced sterilizations <a href="https://www.uvm.edu/~lkaelber/eugenics/" target="_blank">into the 1970s</a>). In recent years, some policymakers and scientists have expressed concerns about how gene-editing technologies could reanimate the eugenics nightmares of the 20th century. </p><p>Currently, the U.S. doesn't explicitly ban human germline genetic editing on the federal level, but a combination of laws effectively render it <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">illegal to implant a genetically modified embryo</a>. Part of the reason is that scientists still aren't sure of the unintended consequences of new gene-editing technologies. </p><p>But there are also concerns that these technologies could usher in a new era of eugenics. After all, the function of a designer baby industry, like the one in the "Genetic Pressure" series, wouldn't necessarily be limited to eliminating genetic diseases; it could also work to increase the occurrence of "desirable" traits. </p><p>If the industry did that, it'd effectively signal that the <em>opposites of those traits are undesirable. </em>As the International Bioethics Committee <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">wrote</a>, this would "jeopardize the inherent and therefore equal dignity of all human beings and renew eugenics, disguised as the fulfillment of the wish for a better, improved life."</p><p><em>"Genetic Pressure Volume I: Baby Steps"</em><em> by Eugene Clark is <a href="http://bigth.ink/38VhJn3" target="_blank">available now.</a></em></p>Octopus-like creatures inhabit Jupiter’s moon, claims space scientist

The 3 layers of your identity.
Answering the question of who you are is not an easy task. Let's unpack what culture, philosophy, and neuroscience have to say.
- Who am I? It's a question that humans have grappled with since the dawn of time, and most of us are no closer to an answer.
- Trying to pin down what makes you you depends on which school of thought you prescribe to. Some argue that the self is an illusion, while others believe that finding one's "true self" is about sincerity and authenticity.
- In this video, author Gish Jen, Harvard professor Michael Puett, psychotherapist Mark Epstein, and neuroscientist Sam Harris discuss three layers of the self, looking through the lens of culture, philosophy, and neuroscience.
