Opportunities and challenges with CRISPR-Cas mediated homologous recombination based precise editing in plants and animals
CRISPR-Cas Homology directed repair (HDR) Non-homologous end joining (NHEJ) Knock-in Gemini virus replicon (GVR) Gene targeting (GT)
2023/11/16
The genome editing has revolutionized the agriculture and human therapeutic sectors by its ability to create precise, stable and predictable mutations in the genome. It depends upon targeted double-st...
Aaron Wagner, professor of electrical and computer engineering at Cornell, has been thinking about the fundamental assumptions surrounding the use of feedback information in digital communication stra...
Light pollution is disorienting animals that navigate by the night sky

Madagascar is renowned for its unique and varied biodiversity, which spans dry grasslands, wet rain forests, mangroves and deserts. This variety, combined with the island's isolation and size, has fos...
Climate regulation changed with the proliferation of marine animals and terrestrial plants
Climate regulation carbon-silicon cycle temperature
2021/8/3
Earth's climate was relatively stable for a long period of time. For three billion years, temperatures were mostly warm and carbon dioxide levels high - until a shift occurred about 400 million years ...
Better predicting how plants and animals will weather climate extremes

2021/8/4
A team of scientists has devised a more accurate way to predict the effects of climate change on plants and animals -- and whether some will survive at all.
Animals' ability to adapt their habitats key to survival amid climate change
climate change animal habitat
2021/8/4
A research group of scientists from North America, Europe and Africa concluded that animals' ability to respond to climate change likely depends on how well they modify their habitats, such as nests a...
Imagine a tropical forest, and you might conjure up tall trees hung with vines, brightly colored birds, howling monkeys and ... rain. Indeed, precipitation patterns, along with temperature, dictate wh...
When it comes to climate, plants and animals aren't so different（图）

Despite fundamental differences in their biology, plants and animals are surprisingly similar in how they have evolved in response to climate, according to a new National Science Foundation-funde...
Upending an evolutionary theory proposed in the 1950s, scientists have found that the groups of animals most resistant to extinction also contain the greatest ecological diversity –- their members per...
