China’s Dark Matter Particle Explorer detected unexpected and

and mysterious signals in its measurement of high-energy cosmic rays, which might bring scientists a step closer to shedding light on invisible dark matte

r. It is the first time a space experiment has reported a detailed and precise electron and positron spectrum up t

o about 5 tera-electron-volts (TeV, corresponding to 1 trillion times the energy of visible light). In this energy ran

ge, the Chinese researchers detected a spectral break at 0.9 TeV and a possible spike at 1.4 TeV.

7.BREAKTHROUGH IN STUDYING WATER STRUCTURE

Using China-developed new atomic force microscopy, scientists have observed the atomic structur

e of the hydrated ions in their natural environment. It is the first time visualizing the atomic structure of hyd

rated ions since the notion was proposed more than 100 years ago. Scientists also discovered that exactly three water molecules are needed to allo

w a single sodium ion to travel 10 to 100 times faster than other ion hydrates – a process that could lead to more ef

ficient ion batteries, anti-corrosion coatings and seawater desalination plants.

8.SUPER-RESOLUTION IMAGING TECHNIQUE

A team of Chinese and U.S. scientists developed a new imaging tec

hnology that can perform high-speed, long-term and super-resolution imaging of intracellular phy

siological processes. Using this technique, a variety of new interactions between organelles were discovered.

9.BALANCED PLANT GROWTH

Crops can be bred with high yields and less fertilizer, as Chinese resea

rchers found a growth-regulating transcription factor GRF4 that had the opposite effect of

a growth-inhibiting protein called DELLA in crops. GRF4 and DELLA existed in a balance that regulated plant gr

owth and nitrogen metabolism. The finding could aid efforts toward reaching sustainable global food safety.
