Beautiful white wall paint does not stay beautiful and white forever. Often, various substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while -- but over time, the color changes and needs to be renewed. Now, special...
Cool paint coatings help pedestrians feel up to 1.5 degrees Celsius cooler in urban setting
A real-world study has shown that the use of cool paint coatings in cities can help pedestrians feel up to 1.5 degrees Celsius cooler, making the urban area more comfortable for work and play.
Scientists close in on TB blood test which could detect millions of silent spreaders
Millions of people are spreading tuberculosis unknowingly - now scientists say they are close to developing a new test that is as simple as the lateral flows used during the Covid pandemic.
Enormous ice loss from Greenland glacier
Ground-based measuring devices and aircraft radar operated in the far northeast of Greenland show how much ice the 79 N-Glacier is losing. According to recent measurements, the thickness of the glacier has decreased by more than 160 meters since 1998. Warm ocean water flowing under the glacier tongue is melting...
Researchers take major step toward developing next-generation solar cells
Engineers have discovered a new way to manufacture solar cells using perovskite semiconductors. It could lead to lower-cost, more efficient systems for powering homes, cars, boats and drones.
Evolutionary history of the formation of forceps and maternal care in earwigs
Researchers examined the developmental processes and reproduction-related behavior of 8 of the 11 families of Dermaptera (earwigs) in detail and compared with those reported in previous studies. The results confirmed that Dermaptera is a polyneopteran order, and the features such as caudal forceps and elaborate maternal care for eggs and...
As we age, our cells are less likely to express longer genes
Aging may be less about specific 'aging genes' and more about how long a gene is. Many of the changes associated with aging could be occurring due to decreased expression of long genes, say researchers. A decline in the expression of long genes with age has been observed in a...
Say hello to biodegradable microplastics
Finding viable alternatives to traditional petroleum-based plastics and microplastics has never been more important. New research shows that their plant-based polymers biodegrade -- even at the microplastic level -- in under seven months.
The heat index — how hot it really feels — is rising faster than temperature
Researchers showed in 2022 that heat index calculations by NOAA based on analyses from the 1970s don't adequately reflect the heat stress humans feel during the extremes of heat and humidity accompanying climate change. Using their revised heat index, the researchers looked at Texas's summer 2023 heat wave and found...
The first Neolithic boats in the Mediterranean
More than 7,000 years ago, people navigated the Mediterranean Sea using technologically sophisticated boats, according to a new study.
