Researchers have developed a model to calculate how quickly or slowly an organism should ideally learn in its surroundings. An organism's ideal learning rate depends on the pace of environmental change and its life cycle, they say. Read more ›

Imagine a sweater that powers electronics to monitor your health or charge your mobile phone while running. This development faces challenges because of the lack of materials that both conduct electricity stably and are well suited for textiles. Now a research group presents an ordinary silk thread, coated with a conductive plastic material, that shows promising properties for turning textiles into electricity generators. Read more ›

Recent rules that require all new building and road projects in England to address and offset their impact on nature are excellent in principle but flawed in their implementation, leading environmental economists argue. In a new study experts criticize the implementation of the Biodiversity Net Gain policy which forces the majority of off-setting to occur within or near development sites rather than where it might most benefit biodiversity. Targeting offsets... Read more ›

The success of the $1 trillion that was recently invested by the U.S. federal government to mitigate climate climate change through the Inflation Reduction Act and the Bipartisan Infrastructure Law largely depends on how well state and local governments spend the money, according to new a commentary.

Chronic, low-level lead poisoning is a major risk factor for cardiovascular disease in adults and cognitive deficits in children, even at levels previously thought to be safe, Low-level lead poisoning is a risk factor for preterm. Annually 5.5 million deaths from cardiovascular disease attributed to low-level lead poisoning; accounts for a loss of 765 million IQ points in children. Read more ›

Most corn and soybean fields in the U.S. are planted with herbicide-resistant crop varieties. However, the evolution of superweeds that have developed resistance to common herbicides is jeopardizing current weed management strategies. Agricultural robotics for mechanical weeding is an emerging technology that could potentially provide a solution. A new study looks at the types of farmers and fields more likely to adopt weeding robots and at what stage of resistance... Read more ›

A new study has found that the COVID-19 pandemic significantly impacted patient safety indicators in U.S. hospitals. The study examined data from the National Database of Nursing Quality Indicators to assess trends in nursing-sensitive quality indicators from 2019 to 2022. The prevention of these very distressing, uncomfortable conditions is considered to be under the nurse's purview and directly influenced by nursing care. Read more ›

Anecdotes abound of wildlife behaving 'drunk' after eating fermented fruits, but despite this, nonhuman consumption of ethanol has been assumed to be rare and accidental. Ecologists now challenge this assumption. They argue that since ethanol is naturally present in nearly every ecosystem, it is likely consumed on a regular basis by most fruit- and nectar-eating animals. Read more ›

An international research team has investigated how nanoplastic particles deposited in the body affect the effectiveness of antibiotics. The study showed that the plastic particles not only impair the effect of the drugs, but could also promote the development of antibiotic-resistant bacteria. Read more ›

Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining chloroplasts (chlorophyll containing structures in the cells of plants and algae) with animal cells was not possible, and that the chloroplasts would not survive or function. However, results showed that photosynthetic action continued for at least two days. This technique could be... Read more ›

Treating anxiety, depression and other disorders may depend on the amygdala, a part of the brain that controls strong emotional reactions, especially fear. But a deep understanding of this structure has been lacking. Now scientists have identified new clusters of cells with differing patterns of gene expression in the amygdala of humans and non-human primates. The work could lead to more targeted treatments for disorders such as anxiety that affect... Read more ›
