Crop-saving soil tests now at farmers’ fingertips

Soil pathogen testing -- critical to farming, but painstakingly slow and expensive -- will soon be done accurately, quickly, inexpensively and onsite, thanks to new research.

Long-term warming trend continued in 2017: NASA, NOAA

Continuing the planet's long-term warming trend, globally averaged temperatures in 2017 were 1.62 degrees Fahrenheit (0.90 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists.

Ancient DNA data fills in thousands of years of human prehistory in Africa

By sequencing the ancient genomes of 15 individuals from different parts of Africa, researchers reporting in the journal Cell on Sept. 21 have reconstructed the prehistory of humans on the continent, going back thousands of years. The findings shed light on which human populations lived in eastern and southern Africa between 8,000 and 1,000 years ago, the researchers say.

Novel HIV vaccine candidate is safe and induces immune response in healthy adults and...

New research shows that an experimental HIV-1 vaccine regimen is well-tolerated and generated comparable and robust immune responses against HIV in healthy adults and rhesus monkeys. Moreover, the vaccine candidate protected against infection with an HIV-like virus in monkeys.

Genetic behavior reveals cause of death in poplars essential to ecosystems, industry

Scientists studying a valuable, but vulnerable, species of poplar have identified the genetic mechanism responsible for the species' inability to resist a pervasive and deadly disease. Their finding could lead to more successful hybrid poplar varieties for increased biofuels and forestry production and protect native trees against infection.

Zooplankton rapidly evolve tolerance to road salt

A common species of zooplankton—the smallest animals in the freshwater food web—can evolve genetic tolerance to moderate levels of road salt in as little as two and a half months, according to new research.

Remote sensing data reveals hundreds more species at risk of extinction

Existing assessments of extinction risk would benefit from modern geospatial technologies, say scientists, who warn that there are hundreds more species who are at risk of extinction than is currently recognized.

Understanding 6th-century barbarian social organization and migration through paleogenomics

Applying a comprehensive analysis of genetic, historical, and archeological factors in two 6th-century barbarian cemeteries, researchers have gleaned new insights into a key era known as the Migration Period that laid the foundation for modern European society.

Newly described human antibody prevents malaria in mice

Scientists have discovered a human antibody that protected mice from infection with the deadliest malaria parasite, Plasmodium falciparum. The research findings provide the basis for future testing in humans to determine if the antibody can provide short-term protection against malaria, and also may aid in vaccine design. Currently, there is no highly effective, long-lasting vaccine to prevent malaria.

Flood frequency of the world’s largest river has increased fivefold

A recent study of more than 100 years of river level records from the Amazon shows a significant increase in frequency and severity of floods.
