India has conducted its first-ever survey of snow leopards, estimating that there are 718 of these big cats living in the country's mountainous regions. This accounts for approximately 10 to 15 percent of the global population. The survey, which took place between 2019 and 2023, was led by the Wildlife Trust of India. In other news, a synthetic material that imitates leaf structure has been developed, which could potentially hide objects from cameras in green areas. Additionally, a piece of mammoth ivory with carved holes found in Germany is believed to be a tool for making ropes, dating back 37,000 years and representing the earliest known evidence of rope-making.

A report from the Chinese Academy of Sciences discusses the development of a multi-deformable interpenetrating network thermosensitive hydrogel fluorescent device for the real-time and visual detection of nitrite in food. The hydrogel material used in the device has a stable structure and can be easily prepared into various sensing devices. When combined with a smartphone system, the device can accurately quantify nitrite levels and differentiate dosage with the naked eye. This research expands the applications of hydrogel materials and contributes to the detection of hazardous materials in food safety. [Extracted from the article]

A study conducted by researchers at the Chinese Academy of Sciences in Shenzhen, People's Republic of China, has found that cancers have a higher uptake and consumption of carbohydrates compared to normal cells, making carbohydrates an effective tool for targeting cancer. The researchers developed a glycooligomer construction methodology that allows for the synthesis of sequence-controlled glycooligomers, which were found to be taken up by cancerous cells at a significantly higher rate than normal cells. The study suggests that these glycooligomers have potential applications in targeted cancer diagnosis and therapy. For more information, readers can refer to the article "Sequence-controlled Glycooligomers for Tumor Targeting" published in Cell Reports Physical Science. [Extracted from the article]
