You can sense not only the sixth finger, but also its length.
The brain allocates neurons that regulate sensation or movement to parts of the body, so it can be said that the brain contains a map of the body, but studies suggest that it may not be so "reliable" at times. In 2016, a scientist conducted an experiment that made subjects think they had a sixth finger on one hand, and another shouted: "Witchcraft!" But the illusion only lasted a very short time. So another research team decided to repeat the experiment and managed to extend the duration of the illusion, which was published in 2020 in the journal Perception. The team then published a new study in 2021 in Cognition: they not only gave subjects the illusion of a sixth finger, but also managed to control the length of their perception of a finger they had never seen before.

These people never feel full, but the problem lies in their cerebellum.
Prad-Willie syndrome (Prader-Willi syndrome) is a rare genetic disease in which people never feel full. This lack of satiety can lead to severe obesity, which in turn leads to life-threatening diseases. Although the fist-sized cerebellum has never been linked to hunger before, scientists have found that the cerebellum plays a key role in regulating satiety in patients with Prad-Willie syndrome.

Water is good for all things but not for dispute. | Wang Yanxin
Water is the source of life. From the point of view of geoscience, the water on the earth moves under the action of solar heat energy, earth gravity and molecular energy, and the phase changes occur constantly, from the troposphere of the atmosphere to the depth of the lithosphere, forming a hydrosphere tens of kilometers thick, which has become a basic feature that distinguishes the earth from other planets.

[Earth interview] Academician Li Tingdong: science popularization is the biggest public welfare project.
General Secretary Xi Jinping said that scientific and technological innovation and scientific popularization are the two wings for realizing innovation and development, and scientific popularization should be placed in the same important position as scientific and technological innovation. Without the general improvement of the scientific quality of the whole people, it will be difficult to establish a grand army of high-quality innovation. " Academician Li Tingdong has a lot to say about the importance of science popularization.

Deciphering the black land
The fragrance of rice flowers in black soil There is a saying in the geological industry that "look at the color and recognize the composition". The black soil is black because it contains more dark black humus. Humus can not only provide rich nutrients such as nitrogen, phosphorus and sulfur for plant growth, but also make black soil have a unique structure-aggregate structure. Humus, like glue, binds soil particles into aggregates of several millimeters, which are called small reservoirs and small fertilizer reservoirs of plant roots, which are unmatched by clay, sand and other properties. Therefore, the black soil has high fertility and good character, which is worthy of the reputation of the king of the soil.

China is rich in volcanic geological relics, and 25 national geoparks with volcanoes as the theme have been built. Each Geopark has its own unique volcanic landscape, which not only has a high ornamental value, provides us with a good place for leisure and entertainment, but also can better protect the geological relic landscape and ecological environment. More importantly, they are important witnesses to the evolution of the earth's history, a window through which we can spy on the earth's movement, and a natural place for popular science education in geology.
Under the influence of the neotectonic movement, five submarine volcanic activities occurred in the coastal-shallow sea environment around Weizhou Island. 1.42 million years ago, Weizhou Island played the symphony of Weizhou Island volcanic eruption. at that time, the eruption took place in the crater of Henglushan volcano, and the basaltic lava overflowed from the volcanic cone to flow around, forming a shield-shaped volcanic topography with high and low surrounding areas in the center of Weizhou Island. At present, the basalts formed in this period are mainly hidden below sea level, but some basalts can be seen along the intertidal zone when the tide goes out in the western corner and Houbeitang in the north of Weizhou Island. they are the founders of Weizhou Island. 36000 years ago, volcanic activity was dominated by exhalation magma eruption, which formed typical low-level crater and thick basement wave accumulation, experienced weathering and marine erosion, and shaped the geomorphological landscape of Weizhou Island today.
