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 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?

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.

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 modern world relies on portable electronic devices such as smartphones, tablets, laptops, cameras or camcorders. Many of these devices are powered by lithium-ion batteries, which could be smaller, lighter, safer and more efficient if the liquid electrolytes they contain were replaced by solids. A promising candidate for a solid-state electrolyte is a new class of materials based on lithium compounds, presented by physicists from Switzerland and Poland.

A team at British Antarctic Survey (BAS) examined the potential distribution of over 900 species of shelf-dwelling marine invertebrates under a warming scenario produced by computer models. They conclude that, while some species in some areas will benefit, 79% of the species native to the region will lose out. This has important implications for future resource management in the region.

In June 2017, three critically endangered North Atlantic right whale carcasses were spotted floating in the Gulf of St. Lawrence. In the weeks that followed the number of dead right whales rose to 10, while three more were found entangled alive in fishing gear. (The total number of deaths may be as high as 12.)

For a species with approximately 500 surviving animals in the world, this was a crisis — an unprecedented die-off signalling a troubled outlook for the species.

Four new tender fruit varieties are coming soon to Canada.

After 18 years of research and testing, the University of Guelph is poised to release two varieties of yellow Japanese plums and two varieties of early peaches.

UCLA physicists have proposed new theories for how the universe’s first black holes might have formed and the role they might play in the production of heavy elements such as gold, platinum and uranium.
