How China’s Communist Party Is Stoking Climate Alarmism At Elite Colleges

Imagine if your primary opponent in the world, a country that regularly steals high-tech military, industrial and medical secrets from you, was able to influence research in your universities solely for their benefit. Unless you had a national death wish,…

New study sheds light on function of sex chromosomes in turtles

(Iowa State University) A new study led by an Iowa State University scientist sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study looks at a species of softshell turtle, but the results could help to illuminate an important evolutionary process in many species. The research centers on a process known as sex chromosome dosage compensation.

Southeastern US herbaria digitize three million specimens, now freely available online

(Botanical Society of America) The National Science Foundation recently provided funding to over 100 herbaria across the Southeast U.S. to digitize more than three million plant specimens collected by botanists and naturalists across the country. Researchers tracked the speed and productivity of staff and students who handled the specimens, from the collection drawers to online repositories, to provide institutions with a framework to better determine the time and money needed to digitize remaining collections.

Global warming may limit spread of dengue fever, new research finds – Penn State News

UNIVERSITY PARK, Pa. — Infection with dengue virus makes mosquitoes more sensitive to warmer temperatures, according to new research led by Penn State researchers. The team also found that infection with the bacterium Wolbachia, which has recently been used to…

RNA breakthrough creates crops that can grow 50% more potatoes, rice

(University of Chicago) A new RNA breakthrough is allowing plants to yield dramatically more crops and increase drought tolerance, which could have an impact on food scarcity and production as climate change threatens ecosystems. In initial tests, adding a gene encoding for a protein called FTO to both rice and potato plants increased their yield by 50% in field tests – and the plants grew significantly larger, produced longer root systems and were better able to tolerate drought stress.

California’s carbon mitigation efforts may be thwarted by climate change itself

(University of California – Irvine) To meet an ambitious goal of carbon neutrality by 2045, California’s policymakers are relying in part on forests and shrublands to remove CO2 from the atmosphere, but researchers at the University of California, Irvine warn that future climate change may limit the ecosystem’s ability to perform this service.

Tiny organisms shed big light on ocean nutrients

(Bigelow Laboratory for Ocean Sciences) Sweeping changes in marine nutrients may seem to be a likely consequence of increasing global temperatures; however, new research suggests that processes below the ocean surface could play a larger role than previously thought.

Stem-Cell Based ‘Cure’ for Type-1 Diabetes Draws Nearer, With FDA Trials Launched

While type-2 diabetes is largely preventable, type-1 diabetes is a disruptive autoimmune disorder that was once thought incurable. ‘Once’ is the keyword here, as a new and uncontroversial form of stem cell treatment should be able to cure the disease once and for all. Relying on transforming a small piece of adult skin tissue into […]

Study examines the role of deep-sea microbial predators at hydrothermal vents

(Woods Hole Oceanographic Institution) The hydrothermal vent fluids from the Gorda Ridge spreading center in the northeast Pacific Ocean create a biological hub of activity in the deep sea. There, in the dark ocean, a unique food web thrives not on photosynthesis but rather on chemical energy from the venting fluids. Among the creatures having a field day feasting at the Gorda Ridge vents is a diverse assortment of microbial eukaryotes, or protists, that graze on chemosynthetic bacteria and archaea.

How a butterfly tree becomes a web

(SMBE journals (Molecular Biology and Evolution and Genome Biology and Evolution)) Scientists reveal a key role for interspecific gene flow in the continent-wide adaptive radiation of the Heliconius butterflies.
