Smart home products such as lamps controlled via mobile devices are becoming ever more popular in private households. We would, however, feel vulnerable in our own four walls if strangers suddenly started switching the lights in our homes on and off. Researchers at the IT Security Infrastructures group, FAU have discovered security problems of this nature in smart lights manufactured by GE, IKEA, Philips and Osram.
Scientists have developed a camera that can see through the human body.
The camera is designed to help doctors track medical tools known as endoscopes that are used to investigate a range of internal conditions.
The dramatic, worldwide loss of biodiversity is one of today's greatest environmental problems. The loss of species diversity affects important ecosystems on which humans depend. Previous research predominantly addressed short-term effects of biodiversity in small experimental plots planted with few randomly selected plant species. These studies have shown that species-poor plant assemblages function less well and produce less biomass than species rich systems.
According to the head of the works Tatiana Volova, Professor of SibFU and the Head of Laboratory in the Institute of Biophysics KSC of SB RAS, development of a new generation of drugs with the use of bio-decomposable materials which decompose under the influence of the microflora to innocuous products and provide a gradual release of the active principle into the soil, is the newest area of research in the field of agriculture. For example, nitrogen is one of the elements, which is often lacking for the growth and development of plants. Plant-available nitrogen in the soil is usually small. Moreover, its compounds are chemically very mobile and easily leached from the soil. In this connection there is the task of developing such forms of nitrogen fertilizers that provide slow release nitrogen and the constancy of its concentration in the soil.
Researchers from the United States and China have proposed an idea that could improve China’s air quality, but they’re not atmospheric scientists. They’re agronomists.
“China’s poor air quality is caused by a combination of coal burning and particulates from soil erosion. The Loess Plateau is the major source of erosion in China, and air quality there is just terrible. If erosion in the Loess Plateau can be improved, air quality will improve,” says D.K. Lee, an agronomist in the Department of Crop Sciences at the University of Illinois.
The Labrador Sea in the North Atlantic is one of the few areas in the world ocean where cold, saline seawater sinks to large depths and forms deep water. This convection process also transports oxygen into the deep sea. A team of scientists from Scripps Institution of Oceanography (San Diego, California), Dalhousie University (Halifax, Canada) and GEOMAR Helmholtz Centre for Ocean Research Kiel have now published the analysis of data obtained from the mooring K1 in the international scientific journal Geophysical Research Letters. The results show that in winter 2014/2015 an unusually high amount of oxygen was absorbed by the ocean in the region. The actual oxygen uptake at the sea surface is very difficult to determine directly, but the scientists were able to derive the oxygen uptake from the oxygen content measured throughout the water column. One of the questions the scientists were concerned with: Can the strong oxygen uptake in the Labrador Sea compensate the global oxygen loss of the ocean?
