A new study sheds light on the intricate interplay of brain regions involved in nicotine's effects on the human brain.

Millions of U.S. households would benefit from heat pumps, but the cost of installing the technology needs to come down to make their use a more attractive proposition.

Many neurodegenerative diseases, such as dementia, are characterized by the abnormal aggregation of proteins inside cells, and treatments are being developed to break them up. But new research suggests that for some diseases, the aggregates are not directly killing cells. Aggregates prevent a protein, SIFI, from switching off the cells' stress response, and the constant stress kills cells. This suggests a strategy to treat these diseases without needing to mop up protein aggregates.

Researchers are further improving CRISPR's versatility to engineer new grasses and yeasts for biochemical production.

Australian birds that live on islands are among the species most at risk of extinction, a first-of-its-kind study has shown. Australia has over 750 native bird species. But many of them are facing an uncertain future.

Scientists develop novel underwater bio-adhesive patches with mussel adhesive protein.

Desert ants find their way during an early learning phase with the help of the Earth's magnetic field. The associated learning process leaves clear traces in their nervous system.

Marine heatwaves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions -- as shown in a new study.

An estimated 11,000 sq miles or 28,707 sq kilometers of Greenland's ice sheet and glaciers have melted over the last three decades, according to a major analysis of historic satellite records.

A new study by researchers has revealed a sustainable method of efficiently converting waste heat into electricity using Irish wood products, while minimizing costs and environmental impact.

Oxytocin, a naturally occurring chemical in the brain, plays a crucial role in various cognitive functions, including memory. A recent study revealed that the activation of neurons in the supramammillary nucleus of the mouse brain enhances performance in object recognition tasks. This discovery implies that specific oxytocin neurons play a pivotal role in modulating object recognition memory in mice.

Researchers have created a new version of a microbe to compete economically with E. coli -- a bacteria commonly used as a research tool due to its ability to synthesize proteins -- to conduct low-cost and scalable synthetic biological experiments.

For the first time, researchers have investigated how ropes and fishing lines are handled by the Norwegian commercial fishing industry. The fishing fleet loses almost 400 tons of rope in Norwegian waters every year.

A new clinical trial suggests that a combination of the drug vorinostat and immunotherapy can coax HIV-infected cells out of latency and attack them. The findings highlight how close -- yet still far -- researchers have come to developing a cure for HIV-1.

Researchers have shed new light on how viral evolution, population immunity, and the co-circulation of other flu viruses shape seasonal flu epidemics.

Sandalwood oil has been used worldwide for centuries. Now, a study is the first to demonstrate in vivo the chemo-preventive properties of a by-product of the oil in a mouse model. Results show administering alpha-santalol reduced visible prostate tumors, protected the normal tissue, and delayed progression from a precancerous condition to a high-grade form of cancer. These findings are significant because mortality in prostate cancer patients is mainly attributable to advanced stages of the disease.

The Joro spider was first spotted stateside around 2013 and has since been spotted across Georgia and the Southeast. New research has found more clues as to why the spider has been so successful in its spread. The study found the invasive orb-weaving spider is surprisingly tolerant of the vibrations and noise common in urban landscapes. In this new study, researchers examined how Joro spiders can live next to busy roads, which are notably stressful environments for many animals.

New research examined how often people experiencing binge eating are also using cannabis recreationally, and whether patients who use cannabis experience more severe eating disorder symptoms or symptoms of struggling with mental health.

More time stranded on land means greater risk of starvation for polar bears, a new study indicates. During three summer weeks, 20 polar bears closely observed by scientists tried different strategies to maintain energy reserves, including resting, scavenging and foraging. Yet nearly all of them lost weight rapidly: on average around 1 kilogram, or 2.2 pounds, per day. Some have speculated that polar bears might adapt to the longer ice-free seasons due to climate warming by acting like their grizzly... Читать дальше...

Smelling a familiar scent can help depressed individuals recall specific autobiographical memories and potentially assist in their recovery.

New research revealed that when coral bleaching occurs, corals release unique organic compounds into the surrounding water that not only promote bacterial growth overall, but select for opportunistic bacteria that may further stress reefs.

You can mend a broken heart this valentine s day now that researchers invented a new hydrogel that can be used to heal damaged heart tissue and improve cancer treatments.

The capacity of intestinal stem cells to maintain cellular balance in the gut decreases upon aging. Researchers have discovered a new mechanism of action between the nutrient adaptation of intestinal stem cells and aging. The finding may make a difference when seeking ways to maintain the functional capacity of the aging gut.
