An environmental sciences professors explain why naming new species may be a never-ending journey.

Fire operations-prescribed burning combo reduces wildfire severity up to 72%

Posted: 14 Jul 2021 12:11 PM PDT

Firefighters battling wildfires in the western United States use a variety of suppression tactics to get the flames under control. Prescribed burns, or controlled fires intentionally set to clear shrubs and forest litter before a wildfire ever ignites, can make fire suppression operations almost three times as effective in limiting wildfire severity, according to a new study.

Detecting wildlife illness and death with new early alert system

A new early detection surveillance system for wildlife helps identify unusual patterns of illness and death in near real-time by tapping into data from wildlife rehabilitation organizations across California, explains a new study.

Conversion of genetic information from DNA to proteins: role of mRNA

Posted: 14 Jul 2021 08:06 AM PDT

mRNA plays a key role in the conversion of genetic information from DNA to proteins. Their production is a delicate process. A research team has now identified a crucial factor.

Study highlights need to replace 'ancestry' in forensics with something more accurate

Posted: 14 Jul 2021 08:05 AM PDT

A new study finds forensics researchers use terms related to ancestry and race in inconsistent ways, and calls for the discipline to adopt a new approach to better account for both the fluidity of populations and how historical events have shaped our skeletal characteristics.

Chemistry discovery could remove micropollutants from environment

New research identified a new chemistry approach that could remove micropollutants from the environment.

DNA from 1,600-year-old Iranian sheep mummy brings history to life

Posted: 14 Jul 2021 08:05 AM PDT

A team of geneticists and archaeologists has sequenced the DNA from a 1,600-year-old sheep mummy from an ancient Iranian salt mine, Chehrabad. This remarkable specimen has revealed sheep husbandry practices of the ancient Near East, as well as underlining how natural mummification can affect DNA degradation.

Fungi that live in the gut influence health and disease

Posted: 14 Jul 2021 08:05 AM PDT

Bacteria's role in gut health has received attention in recent years. But new research shows that fungi -- another microorganism that lives within us -- may be equally important in health and disease. Fungi thrive in the healthy gut, but when interactions with the immune system are off-balance, they cause intestinal damage that may contribute to gastrointestinal disease. Additional investigation demonstrate that vaccines could be developed as therapeutics to improve gut health.

Study puts charge into drive for sustainable lithium production

Posted: 14 Jul 2021 08:05 AM PDT

A new study has yielded critical fresh insights into the lithium production process and how it relates to long-term environmental sustainability, particularly in the area of transportation with batteries and electric vehicles.

Researchers begin to unravel the mysteries of kombucha fermentation

Posted: 14 Jul 2021 08:04 AM PDT

Scientists are beginning to unravel the key microorganisms that contribute to the fermentation of kombucha, research that is already aiding large-scale kombucha producers in the fast-growing industry.

Compound derived from turmeric essential oil has neuroprotective properties

Posted: 14 Jul 2021 08:04 AM PDT

Researchers have found that a component derived from turmeric essential oil, ar-turmerone, and its derivatives act directly on dopaminergic neurons to exert a neuroprotective effect on tissue cultures of a Parkinson's disease model. The effect appears to be due to the enhancement of cellular antioxidant potency through Nrf2 activation. The researchers believe that the ar-turmerone derivatives identified in this study can be utilized as new therapeutic agents for Parkinson's disease.

Tamarind shells converted into an energy source for vehicles

Posted: 14 Jul 2021 08:04 AM PDT

A team of scientists has found a way to process tamarind shells which are rich in carbon, converting the waste material into carbon nanosheets, which are a key component of supercapacitors - energy storage devices that are used in automobiles, buses, electric vehicles, trains, and elevators.

Hard to swallow: Coral cells seen engulfing algae

Posted: 14 Jul 2021 08:04 AM PDT

Scientists have seen stony coral cells engulf dinoflagellates - single-celled, photosynthetic algae that are crucial for keeping coral alive. The researchers cultured endoderm-like cells from the stony coral, Acropora tenuis. Around 40% of coral cells incorporated the algae in around 30 minutes and remained healthy for one month. The research is a step towards understanding the partnership between coral and dinoflagellates and could shed light on how coral bleaching occurs.

Rapid evolution in waterfleas yields new conservation insights

Posted: 14 Jul 2021 08:04 AM PDT

The extraordinary ability of animals to rapidly evolve in response to predators has been demonstrated via genetic sequencing of a waterflea population across nearly two decades.

New system for tracking macaws emphasizes species' conservation needs

Posted: 14 Jul 2021 08:04 AM PDT

New data on macaw movements has the potential to greatly improve conservation strategies for the scarlet macaw, as well as similar species of large parrots.

Species of algae with three sexes that all mate in pairs identified in Japanese river

Posted: 12 Jul 2021 07:22 AM PDT

For 30 years, University of Tokyo Associate Professor Hisayoshi Nozaki has visited the Sagami River to collect algal samples to understand how living things evolved different sexes. The threes sexes of the Pleodorina starrii algae are male, female, and a third sex called bisexual in reference to the fact that it can produce both male and female sex cells in a single genotype and exists due to normal expression of the species' genes.
