Some of the assessment tools that measure children's thinking skills in the U.S. may have provided inaccurate information about poor, urban students because they are modeled on wealthier—mostly white—populations.
The amazing survival strategies of polar marine creatures might help to explain how the first animals on Earth could have evolved earlier than the oldest fossils suggest, according to new research. These first simple and now extinct animals might have lived through some of the most extreme, cold and icy periods the world has ever seen. The study appears in the journal Global Change Biology on October 12, 2022.
It seems intuitive: if you want to soften hearts toward marginalized people, show that they are human like everyone else. That's the theory behind untold media messages depicting "outgroups" having relatable experiences, such as images of immigrants eating Thanksgiving dinner or videos of refugees hugging their children.
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory and collaborators at Cold Spring Harbor Laboratory (CSHL) have engineered duckweed to produce high yields of oil. The team added genes to one of nature's fastest growing aquatic plants to "push" the synthesis of fatty acids, "pull" those fatty acids into oils, and "protect" the oil from degradation. As the scientists explain in a paper published in Plant Biotechnology Journal, such oil-rich duckweed could be easily harvested to produce biofuels or other bioproducts.
The Aldabra giant tortoise is one of only two giant tortoise species left in the world, and it is currently on the threatened list. Conservation efforts are underway, but more and better tools to improve the chance of long-term success are greatly needed. A study published today by an international team of researchers has provided such a tool: they have completed and released an extremely high-quality genome sequence that will help to ensure a future for this vulnerable species.
