Specially adapted drones successfully use a "tap and go" approach to apply monitoring tags to whales, speeding up the process and avoiding human interference

Researchers with the Arkansas Agricultural Experiment Staiton have found the first evidence that drought and insect herbivory can create lasting, transgenerational effects in soybeans. The stressors not only affect the parent plants but alter the traits and defenses of their offspring. The research demonstrates some of the positive and negative impacts the stressors have on a plant’s progeny and could be used to develop more resilient crops in the same season.

The team found fossils of Homo that confirm the earliest evidence for the human lineage at 2.8 million years ago as well as evidence of Homo at 2.6 million years ago, solidifying the antiquity of Homo. Unexpectedly, the team also found evidence that Homo overlapped at the site with a different type of hominin, Australopithecus, at 2.6 million years ago.  

A team of international scientists has discovered new fossils at a field site in Africa that indicate Australopithecus, and the oldest specimens of Homo, coexisted at the same place in Africa at the same time — between 2.6 and 2.8 million years ago. The paleoanthropologists discovered a new species of Australopithecus that has never been found anywhere.  

UNLV anthropologist leads international research team find of Ethiopian fossils; details published in Aug. 13 issue of Nature journal.

An international study has revealed that tiny planktonic crustaceans carry a unique microbial signature that better reflects ocean currents and environmental gradients than microbes found freely in seawater. As surface oceans become warmer and more nutrient-depleted, these host-associated microbes, especially those adapted to oligotrophic conditions as in the Mediterranean Sea, may offer early warning signs about the health of marine ecosystems.
