Transparency and trust are the foundations of every successful research partnership, report suggests‎

According to research by the IfM Bonn, strengthening research collaboration between universities and businesses requires regional technology transfer networks in which technology transfer offices at universities and research institutions, as well as chambers of commerce and industry, trade associations, chambers of crafts, business-related networks and financial intermediaries, all play an active role. In this way, networking opportunities could be pooled and examples of good practice highlighted.

How high turnover rates in Tanzania's agro-dealer sector affect farmer fertilizer adoption‎

Smallholder farmers in sub-Saharan Africa adopt agricultural inputs, including fertilizer, at low rates, contributing to low agricultural productivity. Previous research has shown that insufficient information and distrust in the quality of products for sale in local markets are among the reasons for low rates of fertilizer adoption and application. In a new study published in the American Journal of Agricultural Economics, University of Illinois Urbana-Champaign researchers examined the agricultural marketplace in Tanzania, finding that frequent turnover among local agro-dealers affects farmer perceptions of product quality and has implications for broader market functioning.

A new mechanism for reading extra-long genes in neurons‎

Neurons in humans and other mammals express many exceptionally long genes, ranging from more than 100 kbp to more than 2 Mbp, that are important for forming synapses and neural circuits. In general, genetic information is read from DNA into RNA. This process is called transcription. The longer a gene is, the more time it takes to read from beginning to end. In addition, gene expression must be regulated at several steps. Neurons are therefore thought to require special mechanisms to read long genes accurately and stably, but the details of these mechanisms have remained unclear.

Study explores new photonics advance: Topology imprinting in nonlinear metasurfaces‎

Light is traditionally described by properties such as wavelength, amplitude, phase and polarization. Advances in optics have shown that light can also be shaped into complex spatial patterns known as structured light, enabling new ways to carry information and interact with matter for applications in imaging, optical communications and information processing.

Four in 10 young people don't see 'buy now, pay later' as debt‎

The way a product is labeled can change how consumers think about it. "No added sugar" or "99% fat-free" can make food sound healthier than it really is.

Greyhound racing just turned 100, and says its dogs are fine. But are they?‎

This year, greyhound racing in Britain turns 100 years old. The first race took place on July 24, 1926, in Manchester, where six dogs chased a mechanical hare around a track.

High-resolution weather data could pinpoint neighborhoods facing greatest heat stress‎

Heat stress is a leading cause of weather-related deaths and can be especially dangerous in cities, where phenomena like urban heat islands drive temperatures higher than in surrounding rural areas. Now, a new dataset developed by the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR) aims to provide city governments and health officials with information that could minimize heat impacts on residents.

New species of 240-million-year-old prehistoric animal could reshape dinosaur origins timeline‎

A new prehistoric animal species from Tanzania dating to around 240 million years ago, during the Triassic period, has been described by an international team of researchers. Led by the University of Bristol, the new species, named Dinodontosaurus isiyavamanda, could help scientists refine the age of one of the world's most significant fossil sites and reshape the timeline of early dinosaur evolution.

Plasma and electricity convert CO₂ into methanol, butane and other useful chemicals‎

Carbon dioxide (CO₂) can be harmful to the environment in large amounts but can be used in the production of fuels and other useful chemicals. Doing so isn't easy, though. Now, Yale researchers have developed a new way to combine electrocatalysis and plasma to efficiently and practically generate a number of valuable products from the gas. The results are published in Nature Catalysis.

Weather forecasts are significantly less accurate in poorer countries, analysis finds‎

Weather forecasts inform countless everyday decisions—from farmers deciding when to sow crops and energy companies anticipating demand to public authorities preparing for heat waves. But how useful those forecasts are depends considerably on where people live.
