Researchers develop sensors for continuous corn growth monitoring‎

When is the best time to apply nitrogen? What plant response was there to fertilizer or any number of other treatments? There is a general answer to those questions now, but what if plant breeders and agronomists could download data from continuously monitored cornstalks and ears to develop specific answers for those questions?

Lab-grown neurons retain features of embryonic development‎

Scientists from Skoltech, together with colleagues from the Kharkevich Institute for Information Transmission Problems of the Russian Academy of Sciences, Lomonosov Moscow State University and other organizations, conducted a comparative study of the 3D genome organization in neurons derived from induced pluripotent stem cells and in neurons of the adult human brain. The authors collected and processed more than 300 3D genome maps covering 62 human samples and 34 mouse samples, including data on embryonic stem cells, induced pluripotent stem cells, neural progenitors, fetal and postmortem neurons, as well as neurons differentiated in vitro.

Digitalization front-runners are more vulnerable to cyberattacks‎

For many business leaders, digitalization is associated with promises of greater efficiency and productivity.

Study maps Nelore cattle microbiota to reduce methane emissions‎

Researchers at the Brazilian Agricultural Research Corporation (EMBRAPA) are studying the relationship between the genetics of Nelore cattle and the microorganisms in their guts (microbiota). Nelore cattle are the most widely raised beef breed in Brazil. The goal is to develop strategies that reduce emissions of methane—a major greenhouse gas—and improve the animals' feed efficiency.
