One year after contracting COVID-19, they still face a higher risk of depression

Patients who have been infected with the new crown virus may still face different symptoms related to the new crown after recovery, even if the original new crown symptoms are not serious. This long-term sequelae is not unique, and its effects have attracted sustained attention from the scientific community. Recently, a large-scale study involving up to 150,000 people with new crown infection showed that new crown infection was associated with an increased risk of various mental health disorders in the following year, including depression, anxiety, drug or alcohol abuse, sleep disorders, cognitive decline, etc.

The world's smallest battery can power a computer the size of a grain of dust

Computers are getting smaller, and the trend continues. Smart dust applications (microelectronic devices), such as biocompatible sensor systems implanted in the human body, require computers and batteries that are smaller than dust, but so far have been hampered by a number of factors, such as the lack of on-chip power sources that can operate anytime, anywhere. Now, scientists have made this dust-sized microcomputer possible. In their latest study, they discuss how battery-powered smart dust applications can be implemented at submillimeter scales and demonstrate the world's smallest battery to date as an application-oriented prototype.

The mystery of the dark side of hot Jupiter is revealed for the first time

Recently, astronomers at the Massachusetts Institute of Technology in the United States obtained the sharpest image of the permanent dark side of an exoplanet with a star "tidally locked". The planet is the hot Jupiter WASP-121b, a giant gas giant that is almost twice the size of Jupiter. Their observations and measurements of the planet provide the first detailed view of the exoplanet's global atmosphere.

Plastic consumer goods can lead to obesity

Researchers at the Norwegian University of Science and Technology found in the study that plastic consumer products contain potent metabolic disorder chemicals (MDCs), and after exposure to MDC, pre-3T3-L1 fat cells in mice will differentiate into fat cells and accumulate triglycerides, and eventually form similar to mature white fat cells; considering that humans are often exposed to a large number of plastic products, the researchers concluded that plastic chemicals may contribute to the formation of obesity in humans.

Eating vegetables does not reduce the risk of cardiovascular disease

Some studies believe that eating more vegetables helps reduce the risk of cardiovascular disease (CVD). This theory seems reasonable at first glance, because vegetables contain ingredients such as carotenoids and vitamin E that can prevent cardiovascular disease. However, a new study published in Frontiers in Nutrition suggests that eating vegetables may have little effect on preventing cardiovascular disease, whether eaten raw or cooked.

The new technology promises to make vaccines no longer need to be refrigerated

Australia's Federal Scientific and Industrial Research Organization issued a communiqué on the 22nd, saying that a breakthrough technology developed by the organization's researchers allows vaccines to be stored at room temperature, thereby facilitating the transportation of vaccines to remote areas that lack refrigerated supply chains. They encapsulate a number of live viral vaccines with a soluble crystalline material called "metal-organic frameworks (MOFs)" and found that the crystalline material protected vaccine integrity for up to 12 weeks at temperatures of 37 degrees Celsius. In the past, under non-refrigerated conditions, these vaccines could only be stored for a few days.

Russia developed a brain activity recorder suitable for human-machine interface

Scientists have found birds with teeth in the Cretaceous

In the past 20 years, a large number of bird fossils have been excavated in the Changma Basin of Gansu, China, but most of these fossils are incompletely preserved, and they have been deformed and broken by compression, which has brought great difficulties to related research. Recently, in a study published in the Journal of Systematics and Evolution, the research team examined 6 of the fossils and identified 2 new genera and species, named Meemannavis ductrix and Brevidentavis zhangi. Both species of birds belong to the present bird type, a large group of birds in the Mesozoic Era, in which all living birds evolved. Meemannavis ductrix has no teeth, Brevidentavis zhangi has tiny tapered teeth and anterior tooth bone at the front of the lower jaw.

The Institute of Physics of the Chinese Academy of Sciences has studied the universal physical laws of exotic metals and high-temperature superconductivity

Recently, the Institute of Physics of the Chinese Academy of Sciences and the Beijing National Research Center for Condensed Matter Physics have obtained a universal law between the scattering of exotic metals and the transition temperature of high-temperature superconductivity. For a key high-temperature superconducting system La2-xCexCuO4 (LCCO), the researchers accumulated a sufficient amount of reliable data over several months and observed for the first time a quantification law between the superconducting transition temperature Tc, the relative doped component (x-xc) and the singular metal scattering rate A1 0.5 ~ A10.5. More importantly, the laws obtained from LCCO can be generalized to unconventional superconducting systems such as hollow copper oxides, iron-based superconductors, and organic superconductors, which are universal, indicating that the exotic metal state and the unconventional superconducting state have common drivers. The study was published in Nature.

Researchers use bacteria to ferment carbon dioxide to produce organic matter
