How cells correctly choose active genes

Posted: 05 Nov 2021 10:46 AM PDT

It is essential for cells to control precisely which of the many genes of their genetic material they use. This is done in so-called transcription factories, molecular clusters in the nucleus. Researchers have now found that the formation of transcription factories resembles the condensation of liquids. Their findings will improve the understanding of causes of diseases and advance the development of DNA-based data storage systems.

Comparing photosynthetic differences between wild and domesticated rice

Posted: 05 Nov 2021 10:46 AM PDT

In a new study, researchers compared domesticated rice to its wild counterparts to understand the differences in their photosynthetic capabilities. The results can help improve future rice productivity.

Lighting up chemical reactions for sustainable drug production

Posted: 05 Nov 2021 10:45 AM PDT

Researchers have discovered a new approach for using visible-light to structurally modify bioactive molecules in chemical reactions, providing a possible sustainable alternative to traditional methods that could be used in the design and production of new medicines.

Increasingly frequent wildfires linked to human-caused climate change

Posted: 05 Nov 2021 08:43 AM PDT

A new study strengthens the case that climate change has been the main cause of the growing amount of land in the western U.S. destroyed by large wildfires. And researchers say the trend is likely to worsen.

Save the planet (and your health) by steering clear of sweets and pastries

Need another reason to cut back on sugary foods and drinks, apart from an expanding waistline? They're not helping the environment, contributing to a higher cropland, water scarcity and ecological footprint, according to a new review.

Researchers detect a diffusion barrier inside fly brain

A team of researchers has now demonstrated the existence of an internal diffusion barrier in the brain of fruit flies - in addition to the already known blood-brain barrier.

SARS-CoV-2 variant detected in dogs and cats with suspected myocarditis

Posted: 05 Nov 2021 05:41 AM PDT

A new study reveals that pets can be infected with the alpha variant of SARS-CoV-2, which was first detected in southeast England and is commonly known as the UK variant or B.1.1.7.

New insights into kidney disease with tropical frog models

Posted: 05 Nov 2021 05:41 AM PDT

Using cutting-edge genetic engineering, researchers have developed a model to study hereditary kidney disease with the help of tropical frogs. The method allows them to collect large amounts of data on anomalies, which can then be analyzed using artificial intelligence. The research opens up new opportunities in the search for new treatment approaches for the hitherto incurable disease.

Bood metabolites associated with coffee consumption may affect kidney disease risk

Posted: 04 Nov 2021 02:12 PM PDT

Researchers have identified several metabolites in the blood whose levels are altered by coffee consumption. Levels of 3 of these coffee-related metabolites were significantly associated with individuals' risk of developing chronic kidney disease.

Repurposing carbon dioxide may be key to net-zero emissions

Posted: 04 Nov 2021 01:26 PM PDT

While only a mere 4% of the atmosphere, carbon dioxide plays a vital role in sustaining life on our planet. However, if this delicate balance is disrupted, excess carbon dioxide can pose a formidable threat to our environment and the living beings that reside within.

What sponges can tell us about the evolution of the brain

Posted: 04 Nov 2021 11:08 AM PDT

What can sponges tell us about the evolution of the brain? Sponges have the genes involved in neuronal function in higher animals. But if sponges don't have brains, what is the role of these? Scientists imaged the sponge digestive chamber to find out.

Novel tag provides first detailed look into goliath grouper behavior

Posted: 04 Nov 2021 07:06 AM PDT

A new study reveals detailed behavior of massive goliath groupers. Until now, no studies have documented their fine-scale behavior. What is known about them has been learned from divers, underwater video footage, and observing them in captivity. Using a multi-sensor tag with a three axis accelerometer, gyroscope and magnetometer as well as a temperature, pressure and light sensor, a video camera and a hydrophone, researchers show how this species navigates through complex artificial reef environments, maintain themselves in high current areas, and how much time they spend in different cracks and crevices -- none of which would be possible without the tag.

Ecosystems worldwide are disrupted by lack of large wild herbivores – except in Africa

Posted: 03 Nov 2021 05:26 AM PDT

Biological research has repeatedly demonstrated that the relationship between the producer and the consumer is governed by a scaling law. An international research team has now looked into whether this law of nature can be reproduced in the relationship between the production of plants in an area and the number of large herbivores that graze on them. The study reveals that Africa is the only continent where the scaling law holds true.
