With sensors and cameras, we can learn more about fish behavior, such as schooling – how small fish swim together to avoid predators – and breeding (繁衍). If robotic fish are good at mixing in, we may also learn what it’s like to get eaten by sharks!【1】What do we know about...

In the US and Canada, as many as five billion birds from more than 300 species(物种) live in the forests in the breeding(繁殖的) season. ④Snow forests also help to take in harmful gases(气体). The gases are given off by burning coal oil and gas, which can cause climate change. ...
For generations, scientists have relied on a handful of organisms to study the fundamentals of biology. The usual suspects—fruit flies, zebrafish, and mice, among others—all have short lifespans, small body size, can be bred through multiple generations in the laboratory...
All breeding and colony maintenance was conducted at UIC Biologic Resources Laboratory as previously described [14]. Mice were weaned at P21, ear tagged, and genotyped for 5xFAD. Cages contained four to five mice at the start of housing, which continued unless there was a premature loss of ...
The model focuses on the behaviour of a pair of individuals of two different types (where types can differ in their predation risks, foraging success, or energetic expenditure), over a long series of discrete time steps (in other words, we assume an infinite time horizon). At the start of...
They are usually built near water. Female spotted sandpipers can lay up to 5 clutches per breeding season. Spotted sandpipers breed between May and August.
Our investigation involved the creation of mice with a comprehensive deletion of NONO, and bone marrow chimeric mice that lacked NONO in all their mature B cells. We discovered that the absence of NONO throughout the mouse organism did not impede T-cell development, but resulted in compromised ...
This extent of 13C leakage from the lipid pool into the lean pool was greater than previously reported in mice raised on 13C-palmitic acid [35], yet it remains unclear precisely how the 13C from the palmitic acid tracer was partitioned between the carbohydrate and ...
