Delaying second doses of COVID-19 vaccines should reduce case numbers in the near term; however, the longer term case burden and the potential for evolution of viral 鈥榚scape鈥� from immunity will depend on the robustness of immune responses generated by natural infections and one or two vaccine doses, according to a study from 黑料网爆吃瓜 and Princeton University published today in Science.

Many species might be left vulnerable in the face of climate change, unable to adapt their physiologies to respond to rapid global warming. According to a team of international researchers, species evolve heat tolerance more slowly than cold tolerance, and the level of heat they can adapt to has limits.

Crocodiles are resilient animals from a lineage that has survived for over 200 million years. Skilled swimmers, crocodiles can travel long distances and live in freshwater or聽marine environments. But they can鈥檛 roam far on land. American crocodiles (Crocodylus acutus) are found in the Caribbean and Pacific coasts of the Neotropics but they arrived in the Pacific before Panama existed, according to .

Women today represent two-thirds of all Canadian doctorates in archaeology, but only one-third of Canadian tenure-stream faculty. While men with Canadian PhDs have done well in securing tenure-track jobs in Canada over the past 15 years, women have not, according to a new study from 黑料网爆吃瓜. The current COVID-19 pandemic is likely to exacerbate these existing inequalities.

Mini-Neptunes and super-Earths up to four times the size of our own are the most common exoplanets orbiting stars beyond our solar system. Until now, super-Earths were thought to be the rocky cores of mini-Neptunes whose gassy atmospheres were blown away. In a new study published in , astronomers from 黑料网爆吃瓜 show that some of these exoplanets never had gaseous atmospheres to begin with, shedding new light on their mysterious origins.

Economic growth is often prescribed as a sure way of increasing the well-being of people in low-income countries, but a study led by 黑料网爆吃瓜 and the Institute of Environmental Sciences and Technologies at the Universitat Aut貌noma de Barcelona (ICTA-UAB) suggests that there may be good reason to question this assumption. The researchers set out to find out how people rate their subjective well-being in societies where money plays a minimal role, and which are not usually included in global happiness surveys.

Picture a flower: what do you see? A bright and showy splash of contrasting colours? Well, not all plants produce flowers that are only like that. Some plant species actually produce two types: 鈥渘ormal鈥� ones that look great, and 鈥渞unts鈥� that are small, never open and, rather than attract pollinating insects, instead pollinate themselves.

For decades, scientists have wrestled with rival theories to explain how interactions between species, like competition, influence biodiversity. Tracking microbial life across the planet, researchers from 黑料网爆吃瓜 show that biodiversity does in fact foster further diversity in microbiomes that are initially less diverse. However, diversity rates plateau with increased competition for survival and space in more diverse microbiomes.
