With the help of the CRISPR/Cas molecular scissors, genetic information in a plant can be modified to make the latter more robust to pests, diseases, or extreme climatic conditions. Researchers have now developed this method further to eliminate the complete DNA of specific cell types and, thus, prevent their formation...

Despite Detroit's reputation as a mecca for urban agriculture, a new analysis of the city's Lower Eastside, which covers 15 square miles, found that community and private gardens occupy less than 1% of the vacant land.

Researchers have found that restoration of B cell function in BCR signaling deficiencies involves the interaction of CD22, normally an inhibitory factor, with binding partners on the same cell, which results in upregulation of BCR expression and paradoxically increased BCR signaling. These findings suggest that CD22 could be a novel...

Scientists analyzed the ethanol content of fruit eaten by spider monkeys in Panama, and found that the fruit regularly contained alcohol: between 1% and 2%. The researchers also collected urine samples, most of which contained secondary metabolites of ethanol. The results provide further evidence that our primate ancestors preferentially sought...

New research suggests that social change may depend on the relationship between beneficial behaviors and policies. Using an innovative mathematical model, researchers studied a behavior that benefits groups, but does not spread without policy support, such as a costly measure to mitigate the effects of climate change. The results showed...

Cichlids and stingrays can perform simple addition and subtraction in the number range of one to five. This has been shown in a recent study by the University of Bonn, which has now been published in the journal Scientific Reports. It is not known what the animals need their mathematical...

Less known than Attila's Huns, the Avars were their more successful successors. They ruled much of Central and Eastern Europe for almost 250 years. We know that they came from Central Asia in the sixth century CE, but ancient authors and modern historians debated their provenance. Now, a multidisciplinary research...

Geologists have provided critical new evidence for the timing of volcanic activity in the Karoo province, the largest of the Jurassic magma systems. The remnants of the province are widespread in southern Africa and Antarctica.

Polynesian explorers discovered a treasure trove of unique plants and animals when they arrived in the Marquesas Islands of French Polynesia, according to new research.

Forget sending bull semen out for complicated laboratory tests to learn whether the agricultural animal is virile. Scientists have developed a faster, easier microfluidics method.
