Researchers have identified how cells in our brains work together to join up memories of separate experiences, allowing us to make educated guesses in everyday life. By studying both human and mouse brain activity, they report that this process happens in a region of the brain called the hippocampus.

In a large group of patients with metastatic colorectal cancer, consumption of a few cups of coffee a day was associated with longer survival and a lower risk of the cancer worsening, researchers report in a new study.

The scientists found that the more curved a toe spring is, the less power the foot inside the shoe has to exert when pushing off from the ground while walking. That means foot muscles are doing less work, and this, the researchers hypothesize, may have consequences such as less endurance and make people more susceptible to medical conditions like plantar fasciitis.

Researchers have developed a new method to determine - rapidly, easily and cheaply - how effective two antibiotics combined can be in stopping bacterial growth. The new method is simple for laboratories to use and can provide greater scope for customizing treatment of bacterial infections.

If you want a dog to hunt something down, it helps to let them sniff an item to pick up the scent. Now, researchers have found that scent training honeybees might work in a similar way -- and that this approach could make bees more efficient in pollinating crops. The findings show that honeybees given food scented with sunflower odors led to a significant increase in sunflower crop production.

First-ever measurements provide evidence that extremely cold supercooled water exists in two distinct structures that co-exist and vary in proportion dependent on temperature.

Hubble's sharp view is giving researchers an updated weather report on the monster planet's turbulent atmosphere, including a remarkable new storm brewing, and a cousin of the famous Great Red Spot region gearing up to change color -- again.

Students who are quizzed over class material at least once a week tend to perform better on midterm and final exams compared to students who did not take quizzes, according to a new meta-analysis. The researchers found in addition to frequency, immediate feedback from instructors also seemed to positively impact student performance.

In the 2019 Boeing 737 Max crash, the recovered black box from the aftermath hinted that a failed pressure sensor may have caused the ill-fated aircraft to nose dive. This incident and others have fueled a larger debate on sensor selection, number and placement to prevent the reoccurrence of such tragedies. Researchers have now developed a comprehensive mathematical framework that can help...

Biologists observing the formation of leaves noticed the nuclei moved in bewildering ways. Further investigation uncovered proteins that act as compasses and motors, guiding the divisions of individual cells to create the overall pattern of the leaf.

By comparing genetic variants differing in the two fly populations, researchers found that polygenic traits led to the quickness of adaptation; many genes, each with very small effects, worked together to determine the rate of development. The research illustrates that crop pests and insect disease vectors with similar biology may rapidly respond to changing climates by a similar genetic...

Limitations in DNA sequencing technology make it difficult to detect some major mutations often linked to cancer, such as the loss or duplication of parts of chromosomes. Now, methods developed by computer scientists will allow researchers to more accurately identify these mutations in cancerous tissue, yielding a clearer picture of the evolution and spread of tumors than was previously possible.

Scientists have discovered a new alkali copper halide, Cs5Cu3Cl6I2, that emits pure blue light. The combination of the two halide ions, chloride and iodide, gives the material a crystalline structure made of zigzag chains and peculiar properties that result in highly efficient photoluminescence. This novel compound could be readily used to produce relatively inexpensive and eco-friendly white LEDs...

Preserving terrestrial biodiversity requires more ambitious land-conservation targets to be established and met. At the same time, 'bending the curve' on biodiversity loss needs more efficient food production, and healthier and less wasteful consumption and trade. If undertaken with 'unprecedented ambition and coordination,' these efforts provide an opportunity to reverse terrestrial biodiversity...

For many livestock species, artificial insemination (AI) is standard. But it can be tricky to achieve success the first time, thanks to variability in ovulation timing across the herd. A new study identifies a naturally occurring sugar that slows the maturation of sperm in pigs, opening up the possibility of extending sperm storage time within the female reproductive tract and increasing the...

Researchers provides the first evidence that patients with ocular hypertension may exhibit superior antioxidant protection that promotes resistance to the elevated intraocular pressure associated with glaucoma.

Researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic activity. The finding could provide insights into the enigmatic planet's geological history.

Artificial intelligence (AI) experts report that they have successfully addressed what they call a 'major, long-standing obstacle to increasing AI capabilities' by drawing inspiration from a human brain memory mechanism known as 'replay.'

Researchers found that disfluency, or the difficulty for an individual to process a message, increases people's attitudes toward that message after a time delay.

Scientists have recently developed an all-optical ultrafast imaging system with high spatial and temporal resolutions, as well as a high frame rate. Because the method is all-optical, it's free from the bottlenecks that arise from scanning with mechanical and electronic components.

An international effort that brought together more than 60 ice, ocean and atmosphere scientists from three dozen international institutions has generated new estimates of how much of an impact Earth's melting ice sheets.

A new study presents the first comprehensive assessment of the conservation status of primary forests in Europe -- and shows that many of them are not protected and at risk of being destroyed. The researchers conclude that formal conservation of these forests should be a top priority for countries to meet their climate change and biodiversity goals.

Over 99% of terrestrial ice is bound up in the ice sheets covering Antarctic and Greenland. Even partial melting of this ice due to climate change will significantly contribute to sea level rise. But how much exactly? For the first time ever, glaciologists, oceanographers, and climatologists from 13 countries have teamed up to make new projections.

A dangerous protein named SNAI2 helps cancers metastasize and shields cancer from both the immune system and chemotherapy. Worse, SNAI2 is in a family of proteins that are notoriously hard to fight with drugs. But now researchers have found a way to use the cell's recycling system to control SNAI2, providing a new possibility for treatments.
