PolyU study reveals the mechanism of bio-inspired control of liquid flow, enlightening breakthroughs in fluid dynamics and nature-inspired materials technologies
2024-07-03
The more we discover about the natural world, the more we find that nature is the greatest engineer. Past research believed that liquids can only be transported in fixed direction on species with specific liquid communication properties and cannot switch the transport direction. Recently, The Hong Kong Polytechnic University (PolyU) researchers have shown that an African plant controls water movement in a previously unknown way – and this could inspire breakthroughs in a range of technologies in fluid dynamics and nature-inspired materials, including applications that require multistep and repeated reactions, such as microassays, medical ...
Early-onset El Niño means warmer winters in East Asia, and vice versa
2024-07-03
Fukuoka, Japan—The phenomenon known as El Niño can cause abnormal and extreme climate around the world due to it dramatically altering the normal flow of the atmosphere. In Japan, historical data has shown that El Niño years tend to lead to warmer winters. This case was exemplified recently with Japan’s warm 2023-2024 winter season. However, there have also been cases of cold winters in Japan during El Niño years, such as the one recorded in 2014-2015. Yet, it was unclear as to why this was occurring.

How to avoid wasting huge amounts of energy
2024-07-03
Norway wastes huge amounts of energy. Surplus heat produced by industry is hardly exploited at all.
Researchers at the Norwegian University of Science and Technology (NTNU) have been looking at the possibilities for doing something about this.
“Surplus heat from industrial processes is a huge resource,” says Kim Kristiansen.
He has just completed his PhD on a technology that can harness some of the surplus heat that currently goes to waste. Almost all the heat generated by industrial processes is currently released directly into the air or the ocean, and we are not talking about small amounts. In Norway alone, industry produces ...
Bowel cancer turns genetic switches on and off to outwit the immune system
2024-07-03
Bowel cancer cells have the ability to regulate their growth using a genetic on-off switch to maximise their chances of survival, a phenomenon that’s been observed for the first time by researchers at UCL and University Medical Center Utrecht.
The number of genetic mutations in a cancer cell was previously thought to be purely down to chance. But a new study, published in Nature Genetics, has provided insights into how cancers navigate an “evolutionary balancing act”.
The researchers found that mutations in DNA repair genes can be repeatedly created and repaired, acting as ‘genetic switches’ that take the brakes off a tumour’s growth ...
Shark hatching success drops from 82% to 11% in climate change scenario
2024-07-03
New experimental research shows that the combined effects of ocean warming and acidification could lead to a catastrophic decrease in embryonic shark survival by the year 2100. This research is also the first to demonstrate that monthly temperature variation plays a prominent role in shark embryo mortality.
Oceanic warming and acidification are caused by greater concentrations of CO2 dissolving into marine environments, resulting in rising water temperatures and falling pH levels. “The embryos of egg-laying ...

NARO developed a novel method to analyze “forever chemicals” in the soil
2024-07-03
Concern about the effects of PFAS are of increasing globally. Also there is no accurate method for analyzing multiple PFAS in soil. Hence, a team of PFAS researchers led by NARO et.al sought to develop a stable and accurate method for analyzing multicomponent PFAS in the soil (Ministry of Agriculture, Forestry and Fisheries -MAFF project).
Unlike the PFAS analysis method for water samples, it is difficult to ensure the extraction efficiency of the target PFAS in diverse soil samples. In Japan, there are 381 soil types, with volcanic ash soils being the predominant. Since these soils possess high carbon content, ...
Scientists pinpoint strategies that could stop cats from scratching your furniture
2024-07-03
Many cat owners are familiar with torn cushions, carpets, and couches. The feline instinct to scratch is innate but is often perceived as a behavioral problem by cat owners and sometimes leads to interventions that are not cat friendly.
Now, an international team of researchers has investigated which factors influence undesired scratching behavior in domestic cats. They published their findings in Frontiers in Veterinary Science.
“Here we show that certain factors – such as the presence of children at home, personality traits of cats, and their activity levels – significantly impact the ...
