Harnessing green energy from plants depends on their circadian rhythms      (via sciencedaily.com)     Original source 

Plant hydraulics drive the biological process that moves fluids from roots to plant stems and leaves, creating streaming electric potential, or voltage, in the process. A study closely examined the differences in voltage caused by the concentrations of ions, types of ions, and pH of the fluid plants transport, tying the voltage changes to the plant's circadian rhythm that causes adjustments day and night. According to the authors, this consistent, cyclic voltage creation could be harnessed as an energy source.

Transgenic expression of rubisco factors increases photosynthesis and chilling tolerance in maize      (via sciencedaily.com)     Original source 

Maize is one of the world's most widely grown crops and is essential to global food security. But like other plants, its growth and productivity can be limited by the slow activity of Rubisco, the enzyme responsible for carbon assimilation during photosynthesis. Scientists have now demonstrated a promising approach to enhancing Rubisco production, thus improving photosynthesis and overall plant growth.

Breakthrough discovery uses engineered surfaces to shed heat      (via sciencedaily.com)     Original source 

Splash a few drops of water on a hot pan and if the pan is hot enough, the water will sizzle and the droplets of water seem to roll and float, hovering above the surface. The temperature at which this phenomenon, called the Leidenfrost effect, occurs is predictable, usually happening above 230 degrees Celsius. A team has now discovered a method to create the aquatic levitation at a much lower temperature.

Sexual parasitism helped anglerfish invade the deep sea during a time of global warming      (via sciencedaily.com)     Original source 

Members of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate. Now, researchers show that sexual parasitism arose during a time of major global warming and rapid transition for anglerfishes from the ocean floor to the deep, open sea.

Community science volunteers can set scientific world abuzz with new bumble bee sightings      (via sciencedaily.com)     Original source 

Community science volunteers -- laypeople with an interest in bees and conservation -- significantly contribute to the scientific knowledge of native bumble bees across Canada and the United States. It's buzz worthy confirmation that community science programs can play an important role in monitoring the changing distributions of bumble bees and more.

Strings that can vibrate forever (kind of)      (via sciencedaily.com)     Original source 

Researchers have engineered string-like resonators capable of vibrating longer at ambient temperature than any previously known solid-state object -- approaching what is currently only achievable near absolute zero temperatures. Their study pushes the edge of nanotechnology and machine learning to make some of the world's most sensitive mechanical sensors.

New insights into the degradation dynamics of organic material in the seafloor      (via sciencedaily.com)     Original source 

Many processes in the deep sea are not yet well understood, and the role of microbial communities in particular is often a big unknown. This includes, for example, how organic material that sinks from the water surface to the ocean floor is metabolised -- an important building block for a better understanding of the global carbon cycle.

Improving statistical methods to protect wildlife populations      (via sciencedaily.com)     Original source 

In human populations, it is relatively easy to calculate demographic trends and make projections of the future if data on basic processes such as births and immigration is known. The data, given by individuals, can be also death and emigration, which subtract. In the wild, on the other hand, understanding the processes that determine wildlife demographic patterns is a highly complex challenge for the scientific community. Although a wide range of methods are now available to estimate births and deaths in wildlife, quantifying emigration and immigration has historically been difficult or impossible in many populations of interest, particularly in the case of threatened species.

Powering wearable devices with high-performing carbon nanotube yarns      (via sciencedaily.com)     Original source 

Carbon nanotube (CNT) yarns are promising for flexible and fabric-type wearable materials that can convert waste heat into thermoelectricity. To improve the thermoelectric properties of CNT yarns, researchers dispersed CNT filaments in a highly viscous glycerol, enabling the production of CNT yarn with highly aligned bundles together with surfactants that prevent increased thermal conductivity. This innovative approach can significantly improve carbon nanotube-based thermoelectric materials, making it possible to power wearable devices using just body heat.

The impacts of climate change on food production      (via sciencedaily.com)     Original source 

A new study shows that climate change has led to decreased pollen production from plants and less pollen diversity than previously thought, which could have a significant impact on food production.
