When officials make tough calls on which areas to prioritize for conservation, biodiversity is often their top consideration. But there are several types of diversity, and not all of them overlap perfectly. In a new study, researchers analyzed 20-years' worth of U.S. Forest Service data and show that the simplest measure of diversity is the best predictor of healthy forest growth, providing a roadmap for quickly and efficiently protecting ecological resources.

Scientists have discovered how honeybees can decipher dances by their hive mates that relay directions to food.

Some plant species will 'win' and others will 'lose' as global warming forces them to move uphill, new research shows.

A team of scientists has developed a novel antibiotic named COE-PNH2 that is capable of combating hard-to-treat mycobacterial lung infections. Such infections, which are notorious for resisting conventional treatment, pose a serious health threat, especially to the elderly and those with underlying conditions.

Humans pass on more viruses to domestic and wild animals than we catch from them, according to a major new analysis of viral genomes.

Scientists have found a 'tipping point' in the evolution of fungi that throttles their growth and sculpts their shapes. The findings demonstrate how small changes in environmental factors can lead to huge changes in evolutionary outcomes.

How was complex life able to develop on the inhospitable early Earth? At the beginning there must have been ribonucleic acid (RNA) to carry the first genetic information. To build up complexity in their sequences, these biomolecules need to release water. On the early Earth, which was largely covered in seawater, that was not so easy to do.

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.

It's no surprise that your dog can learn to sit when you say 'sit' and come when called. But a new study has made the unexpected discovery that dogs generally also know that certain words 'stand for' certain objects. When dogs hear those words, brain activity recordings suggest they activate a matching mental representation in their minds.

Researchers at McMaster University and Stanford University have invented a new generative artificial intelligence model which can design billions of new antibiotic molecules that are inexpensive and easy to build in the laboratory.

Spiders that disguise themselves as ants live in many locations around the globe but until now most had been able to avoid detection from fossil researchers as well as predators.

Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall.

A product used to control pest slugs on farms in multiple countries is deadly to least one type of native woodland snail endemic to the Pacific Northwest, according to scientists who say more study is needed before the product gains approval in the United States.

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 young larvae emerged in parallel within the order during evolution.

Following injury, plants release terpenoids to enhance their defenses. Researchers studying terpenoid-enriched essential oils (EOs) have found that rose EO (REO) can stimulate defense genes in tomato leaves. Furthermore, REO attracts herbivores that protect the plant from the moth species, Spodoptera litura, and Tetranychus urticae, a mite pest. This suggests that applying REO could be a sustainable approach to pest management in organic farming.

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 wide range of animals, from worms to humans, in various human cell and tissue types, and also in individuals with neurodegenerative disease. Mouse experiments show that the phenomenon can be mitigated via known anti-aging factors, including dietary restriction.

The first study of humpback whale entanglements in B.C. aquaculture facilities found eight over 13 years, with the curiosity of young whales a potential contributing factor.

New research finds a direct communication path between the lungs and the brain which may change the way we treat respiratory infections and chronic conditions. The lungs are using the same sensors and neurons in the pain pathway to let the brain know there's an infection. The brain then prompts the symptoms associated with sickness. Findings indicate we may have to treat the nervous system as well as the infection.

A research consortium made a recent discovery that the natural molecule trigonelline present in coffee, fenugreek, and also in the human body, can help to improve muscle health and function.
