If so, how would you choose to die?
Well on weekends, welcome to open the “Monthly One Weekly Conjecture.” Here, you can see the latest technology exhibitions in the past week, as well as inventions beyond imagination. At the same time, we are also paying close attention to the interesting evolution of the relationship between people and technology in the AI era. Let us glimpse the tip of the iceberg of the future.

Animal gender can be intervened before birth: is hi, but also sad
Recently, researchers at Hiroshima University in Japan have unexpectedly discovered a disturbingly simple way to separate sperm carrying X chromosomes from sperm carrying Y chromosomes – this may It has a huge impact on the future of mankind.
To understand the importance of this research, let us briefly review the basics of biology: In most mammals, females carry the XX chromosome, while males carry the XY chromosome. The sex of the offspring is the male XY chromosome. The X chromosome produces a female and the Y chromosome produces a male. For a long time, we all thought that sperm is almost the same except for the DNA it carries.
However, when studying the difference in X and Y spermatozoa in mice, Hiroshima University’s team found that about 500 genes in X sperm are active, but not in Y sperm. The researchers used a chemical called resiquimod to bind to the receptor, slowing the movement of the X sperm, and finally separating the X and Y sperm with surprising accuracy: in this experiment, they used the fastest sperm. In vitro fertilization yielded 90% of male pups. When fertilized using the slowest sperm, 81% of female pups were produced.
This research is of great value in animal farming. For example, in a dairy farm, the value of a mother cow is much higher because it produces milk.Yugong cows. In beef production, the value of the bull is much higher than that of the cow. In theory, human sperm can now be separated in the same way, but this will involve enormous ethical and social problems.

A new way to spy on privacy with your smartphone:To embank a smartphone around you
Smartphones can detect the amount of light, air pressure and temperature in the surrounding environment, as well as the environment, through the camera and microphone.
Recently, Eric Larson and Mitchell Thornton, professors at Southern Methodist University, have discovered that mobile motion sensors can also be used to eavesdrop on mobile phones.
The researchers developed an application to realistically simulate this potential attack scenario. The attacker only needs to put several phones with the program on the same table as your computer. You can identify what you typed by tapping the vibration of the keyboard. Even if people around you are talking, about a quarter of the words are perfectly translated.
But don’t worry too much at the moment, because there is a huge challenge in achieving this kind of attack: each type of keyboard is like a different drum, and the vibration of each table is different. So in the moment, no one can complete such a snoop.
“But a technology company like Google should change their policies before these attacks become more viable. They should let users know which application on the phone is accessing the sensor without risk, even if the threat is in this The time is not going to happen,” said researcher Thornton.

Swiss scientists turn breast cancer cells into normal fat:So, fat is fat< /p>
Scientists have been able to induce the transformation of human breast cancer cells into normal fat cells. Although the results of this study are only the first step, they can indeed be regarded as a major breakthrough.
When you cut your fingers, or when the fetus grows out of the organs, the epithelial cells begin to become less like themselves, but more like “liquids” – they become “mesenchymal stem cells.” And then it will be transformed into any cell that the body needs. This process is called epithelial-mesenchymal transition (EMT), which is the use of this pathway or the opposite pathway MET (mesenchymal-epithelial transformation) to spread throughout the body and metastasize. Simply put, this is the principle of cancer spread.
Cancer cells show a high degree of plasticity when undergoing EMT. Scientists have developed a new treatment using this characteristic of cancer cells: Treatment of mice implanted with human breast cancer using a diabetes drug called rosiglitazone and a cancer treatment called trmetatinib. These two drugs make cancer cells use the above pathways for transformation, but they do not spread, but become fat cells.
The exciting thing is that these two drugs have already received FDA (USApproved by the Food and Drug Administration, this therapy will be used in clinical trials. Although the mouse experiment is still only a small step, it has given people some hope in conquering cancer.

Can’t pull down the face to dismiss employees? Practice with VR first:Become overbearing president and need training
Even if you have experienced people in the workplace, you will feel a little tricky in the face of dismissal. According to the MIT Technology Review, Talespin, a company that specializes in virtual reality workplace training, has developed a VR character called Barry to help you improve your “soft” management skills: If you are too blunt about Barry, he will bury his head in his hands, and other mistakes may make him yell.
Virtual reality has been in the training field in recent years. Talespin’s CEO, Kyle Jackson, believes this trend will spread across the office, and he sees growing interest and need for interviewing techniques, difficult conversations, consulting sales, performance assessments, and more. But now the VR role like Barry is stillIt is not perfect, he is still following a fixed script, and can’t interact in a very natural way.

Without talking, this wearable device lets you command:The highest level of laziness is motionless
In July, Neuralink, a brain-computer interface startup founded by Elon Musk, finally unveiled the mystery: Neuralink has developed a system that can send 1,500 electron probes into the mouse brain. It is expected that in the first half of 2020, the testing of the technology will begin on the human body, and the realization of the brain machine seems to be close at hand.
Arnav Kapur, a postdoctoral student at the Massachusetts Institute of Technology Media Lab, has similar ideas and he has already made it. But unlike Musk’s brain, it doesn’t read signals from people’s brains, which involves privacy violations. The prototype device, called Elter Ego, reads information from the nervous system in a voluntary way, and you need to be consciously involved in communicating with the device.
This potentially revolutionary technology works like this: When humans talk, they need to involve hundreds of facial muscles, even if you don’t speak, and don’t move your lips, chin or Facial muscles, just talking to yourself in the heart, the system also captures the subtle nerve activation of your internal language system from the surface of the skin, evenThe source is inside the skin.
If this device is available, it will be very beneficial for patients suffering from Alzheimer’s, stroke, brain damage, Parkinson’s disease and many other diseases that cause language problems. Of course, there are those who are too lazy to move, they can control their smart home without saying a word. You seem to be wearing an anechoic version of Siri, sneaking up to control everything…
