Chinese scientist vanishes after claiming to have made first gene-edited babies

The controversial scientist He Jiankui is currently missing after causing major controversy in late November.

  • He Jiankui caused international controversy by claiming to have used the CRISPR gene-editing tool to modify the genes of two babies.
  • Some reports suggested he was being held under house arrest, though others say that's inaccurate.
  • It's not unusual for people to disappear in China at the hands of government authorities.

Where is He Jiankui?

The scientist who caused international uproar by claiming to have used the CRISPR gene-editing tool to modify the embryos of two babies recently born in China is missing, and it's unclear why.

In a YouTube video published in late November, He stunned the world with claims, which, if true, would be both historic and highly ethically questionable. Almost immediately, geneticists and others in the scientific community decried his research as premature and unethical, criticizing his methods and noting that not enough is known about the consequences of gene editing to pursue the practice at this time.

The co-inventor of CRISPR, Dr. Jennifer Doudna, issued a statement saying He and his colleagues should "fully explain their break from the global consensus that application of CRISPR-Cas9 for human germline editing should not proceed at the present time."

China's Southern University of Science and Technology, where He worked, said it had been unaware of the controversial research, and said it would open an investigation.

The South China Morning Post wrote that He's whereabouts have not been known since last Wednesday. Other reports suggested He had been placed under house arrest by Chinese authorities. A spokeswoman with Southern University said He hadn't been placed under house arrest, but that she couldn't confirm details.

"Right now nobody's information is accurate, only the official channels are," the spokeswoman told the Morning Post, adding that she couldn't "answer any questions regarding the matter right now."

On Thursday, Huai Jinpeng, Party chief and executive vice chairman of the China Association for Science and Technology, said He's work was "extremely abominable in nature" and had "blatantly violated China's relevant laws and regulations."

Xu Nanping, a vice minister for science and technology, told state broadcaster CCTV that the work had "violated the ethical bottom line that the academic community adheres to. It is shocking and unacceptable." The China Association of Science and Technology has ordered an investigation into the matter.

Vanishing in China

Although it's still unclear why He is missing, it's worth noting that it's not uncommon for Chinese citizens, and even high-ranking officials, to go missing after slipping up in public or painting the government in a negative light.

In early November, Lu Guang, a renowned Chinese photographer who documented social injustice and environmental destruction in China, vanished while traveling to a conference in the Xinjiang province. His wife heard from a friend that Lu had been detained by officials.

More broadly, thousands of executives and officials have disappeared in recent years, likely as part of the anti-corruption campaign China began in 2012. The government says its aim is to purge from its ranks officials who abuse power or accept bribes. However, some critics say the primary goal of the program, which was expanded in March, is to allow Party leaders to get rid of opponents and keep everyone in ideological consensus.

Amnesty International has called the campaign, which can result in people being forcefully detained for months without access to a lawyer, as a "systemic threat to human rights in China."

  • U.S. Navy holds patents for enigmatic inventions by aerospace engineer Dr. Salvatore Pais.
  • Pais came up with technology that can "engineer" reality, devising an ultrafast craft, a fusion reactor, and more.
  • While mostly theoretical at this point, the inventions could transform energy, space, and military sectors.

China's "artificial sun" sets new record for fusion power

China has reached a new record for nuclear fusion at 120 million degrees Celsius.

China wants to build a mini-star on Earth and house it in a reactor. Many teams across the globe have this same bold goal --- which would create unlimited clean energy via nuclear fusion.

But according to Chinese state media, New Atlas reports, the team at the Experimental Advanced Superconducting Tokamak (EAST) has set a new world record: temperatures of 120 million degrees Celsius for 101 seconds.

Yeah, that's hot. So what? Nuclear fusion reactions require an insane amount of heat and pressure --- a temperature environment similar to the sun, which is approximately 150 million degrees C.

If scientists can essentially build a sun on Earth, they can create endless energy by mimicking how the sun does it.

If scientists can essentially build a sun on Earth, they can create endless energy by mimicking how the sun does it. In nuclear fusion, the extreme heat and pressure create a plasma. Then, within that plasma, two or more hydrogen nuclei crash together, merge into a heavier atom, and release a ton of energy in the process.

Nuclear fusion milestones: The team at EAST built a giant metal torus (similar in shape to a giant donut) with a series of magnetic coils. The coils hold hot plasma where the reactions occur. They've reached many milestones along the way.

According to New Atlas, in 2016, the scientists at EAST could heat hydrogen plasma to roughly 50 million degrees C for 102 seconds. Two years later, they reached 100 million degrees for 10 seconds.

The temperatures are impressive, but the short reaction times, and lack of pressure are another obstacle. Fusion is simple for the sun, because stars are massive and gravity provides even pressure all over the surface. The pressure squeezes hydrogen gas in the sun's core so immensely that several nuclei combine to form one atom, releasing energy.

But on Earth, we have to supply all of the pressure to keep the reaction going, and it has to be perfectly even. It's hard to do this for any length of time, and it uses a ton of energy. So the reactions usually fizzle out in minutes or seconds.

Still, the latest record of 120 million degrees and 101 seconds is one more step toward sustaining longer and hotter reactions.

Why does this matter? No one denies that humankind needs a clean, unlimited source of energy.

We all recognize that oil and gas are limited resources. But even wind and solar power --- renewable energies --- are fundamentally limited. They are dependent upon a breezy day or a cloudless sky, which we can't always count on.

Nuclear fusion is clean, safe, and environmentally sustainable --- its fuel is a nearly limitless resource since it is simply hydrogen (which can be easily made from water).

With each new milestone, we are creeping closer and closer to a breakthrough for unlimited, clean energy.

The science of sex, love, attraction, and obsession

The symbol for love is the heart, but the brain may be more accurate.

Videos
  • How love makes us feel can only be defined on an individual basis, but what it does to the body, specifically the brain, is now less abstract thanks to science.
  • One of the problems with early-stage attraction, according to anthropologist Helen Fisher, is that it activates parts of the brain that are linked to drive, craving, obsession, and motivation, while other regions that deal with decision-making shut down.
  • Dr. Fisher, professor Ted Fischer, and psychiatrist Gail Saltz explain the different types of love, explore the neuroscience of love and attraction, and share tips for sustaining relationships that are healthy and mutually beneficial.
