Warmer climate may make new mutations more harmful

A warmer global climate can cause mutations to have more severe consequences for the health of organisms through their detrimental effect on protein function. This may have major repercussions on organisms' ability to adapt to, and survive in, the altered habitats of the future. This is shown in a new Uppsala University research study now published in the scientific journal Proceedings of the Royal Society B.

First images of muon beams

A new technique has taken the first images of muon particle beams. Nagoya University scientists designed the imaging technique with colleagues in Osaka University and KEK, Japan and describe it in the journal Scientific Reports. They plan to use it to assess the quality of these beams, which are being used more and more in advanced imaging applications.

A global look at surface soil organic carbon

Healthy soil is paramount to life on Earth. In addition to its importance in agriculture, soil is the foundation for almost every terrestrial ecosystem on Earth. Soil organic carbon (SOC) is frequently used as a gauge of soil health, it plays an important role in terrestrial carbon cycling, and it carries huge implications for climate change adaptation. Understanding these dynamics on a planetary scale will be vital as humanity attempts to feed a growing population under increasing stress from a warming planet.

Nokia and Vodafone showcase record-breaking 100 gigabit fiber broadband

Nokia and Vodafone have announced the successful trial of a new passive optical network (PON) technology capable of delivering speeds up to 100 gigabits per second (Gb/s) on a single wavelength 10 times faster than the most advanced networks available today. This marks the latest industry-first in fiber access for Nokia, following breakthroughs in 10G PON, TWDM-PON, universal PON and 25G PON.

South Africa: Rising temperatures will cost up to 20% of per capita GDP

Temperature rise due to climate change has negatively affected labor productivity in recent decades and will keep damaging it, potentially to a higher extent than what has been estimated in the literature up to now. In South Africa, a future scenario with severe climate change will feature a reduction of per capita GDP of up to 20% by the end of the century compared to an idealized future without the impacts of a changing climate.

Researchers propose programming to support adolescent mothers in areas of conflict

Adolescent mothers often fall through the cracks of educational programming. This is highly problematic given that globally an estimated 12 million girls between the ages of 15-19, and 777,000 girls under the age of 15, give birth each year. In populations affected by conflict and displacement, adolescent girls have an increased likelihood of becoming mothers due to various factors, such as disruptions to schooling, the loss of family members, poverty, gender-based violence, and poor access to healthcare and sexual and reproductive services and resources. There is a lack of support programs for these young mothers, and a continuing need for educational programming.

Coral decline—is sunscreen a scapegoat?

Many household products contain ingredients to protect them against sun damage. These UV filters are found in plastics, paints and textiles, as well as personal care products such as sunscreens and moisturizers. UV filters are entering the aquatic environment in rivers, lakes and oceans. Consider for a moment a beach goer swimming in the ocean or rain washing over plastic playground equipment and running into a stormwater drain—either directly or indirectly, UV filters end up making their way to a waterway.

Double delight: New synthetic transmembrane ion channel can be activated in two ways

Scientists at Tokyo Institute of Technology (Tokyo Tech) and University of Tokyo, Japan, have, for the first time, synthesized a novel artificial transmembrane ion channel modeled on a naturally found transmembrane channel involved in neuron signaling—that responds to both chemical and electrical stimuli. Given its overall properties, this artificial channel opens doors to novel fundamental research into cellular transport and signaling, new possibilities in drug development, and the potential for new types of biosensors.

Scientists develop method to detect fake news

Social media is increasingly used to spread fake news. The same problem can be found on the capital market—criminals spread fake news about companies in order to manipulate share prices. Researchers at the Universities of Göttingen and Frankfurt and the Jožef Stefan Institute in Ljubljana have developed an approach that can recognize such fake news, even when the news content is repeatedly adapted. The results of the study were published in the Journal of the Association for Information Systems.

In the Antarctic, a scientist recruits albatrosses to pinpoint illegal fishing boats

Albatross expert Dr. Henri Weimerskirch, of the French National Centre for Scientific Research (CNRS), turned his favourite seabirds into spies two years ago by fixing them up with loggers that could detect the radar of illegal fishing vessels. The information from this project, known as OCEAN SENTINEL, has helped governments select which parts of the ocean to patrol. But Dr. Weimerskirch wanted to recruit another, possibly better, species to stealth operations. In late 2020, he returned to the remote Kerguelen Islands, in the southern Indian Ocean, to see if they would cooperate. He told Horizon about his expedition.
