Childlessness by circumstance
In birds and other species alike, pairs can face considerable difficulties with reproduction. Scientists have now shown in an extensive analysis of 23,000 zebra finch eggs that infertility is mainly due to males, while high embryo mortality is more a problem of the females. Inbreeding, age of the parents and conditions experienced when growing up had surprisingly little influence on reproductive failures.

CRISPR-induced immune diversification in host-virus populations
Just like humans, microbes have equipped themselves with tools to recognize and defend themselves against viral invaders. In a continual evolutionary battle between virus and host, CRISPR-Cas act as a major driving force of strain diversity in host-virus systems.
Light pollution alters predator-prey interactions between cougars and mule deer in western US
A new study provides strong evidence that exposure to light pollution alters predator-prey dynamics between mule deer and cougars across the intermountain West, a rapidly growing region where nighttime skyglow is an increasing environmental disturbance.
Mystery over decline in sea turtle sightings
The number of sea turtles spotted along the coasts of the UK and Ireland has declined in recent years, researchers say.
Opinion | The alarming reality of global warming – The Breeze
The levels of greenhouse gas emissions are continuously and rapidly increasing, and with that increase comes dangerous and deadly consequences. The earth’s average temperature is expected to reach 1.5 degrees Celsius (34.7 degrees Fahrenheit) as soon as 2030, and with…
RUDN University soil scientist: Paddy soil fertilization can help reduce greenhouse effect
(RUDN University) A soil scientist from RUDN University discovered the effect of fertilization on the ability of the soil to retain carbon. To understand this mechanism, he and his team studied the movement of organic carbon in the soil of rice paddies. The results of the study can help increase the fertility of the paddies while at the same time reducing the volume of greenhouse gases in the atmosphere.
Ground-breaking discovery finally proves rain really can move mountains
(University of Bristol) A pioneering technique which captures precisely how mountains bend to the will of raindrops has helped solve a long-standing scientific enigma.
Remnants of ancient parasites could be shaping our response to coronavirus
(University of Colorado at Boulder) Why are some people more resilient to viruses than others? One scientist, motivated by the COVID-19 pandemic, has proposed an intriguing answer: Exposure to ancient parasites by our ancestors forever altered our genome, shaping the varied responses of our immune systems today.
