Spiders, like humans and many other animals, have distinct personalities. Two studies have unveiled interesting findings about the relationship between personality traits of spiders and their decision-making as well as hunting styles.

Researchers used a baseline comparison of infection and transmission rates of Florida mosquitoes to those from the Dominican Republic, a region associated with numerous human cases. Experts measured mosquito infection and transmission of the emergent strains of chikungunya -- Asian and Indian Ocean – in Aedes aegypti and Aedes albopictus mosquitoes.

Uncertainty and confusion on genetic engineering of main food crops in Africa have delayed the acceptance and application of these crops by smallholder farmers in sub-Saharan Africa, say researchers. Model calculations reveal that the costs of a one year delay in approving the pod-borer resistant cow-pea in Nigeria will cost the country 33 -- 46 million dollars, and more disastrously, will take theoretically 100 to 3000 lives, the team reports.

Delirium is common in elderly hospitalized patients, affecting an estimated 14-56 percent of patients. It frequently manifests as a sudden change in behavior, with patients suffering acute confusion, inattention, disorganized thinking and fluctuating mental status.

For the first time, a team of scientists has calculated the distribution of all light energy contained within the Milky Way, which will provide new insight into the make-up of our galaxy and how stars in spiral galaxies such as ours form.

Three more frog species have been discovered in the Peruvian Andes, raising to five the total number of new frog species the group has found in a remote protected forest since 2012.

German shepherd dogs could be predisposed to health conditions such as arthritis because of the way they have been bred in recent decades, according to a new study.

From 2007-2012, deceased donor kidneys in the United States were offered a median of 7 times before finally being accepted for transplantation. Such refusals may have contributed to racial and ethnic disparities that exist in access to transplantation in the United States.

Frequent alcohol consumption is associated with a reduced risk of diabetes in both men and women, according to a new study, with alcohol consumption over 3-4 week days giving the lowest risks of diabetes.

A world-first systematic review into the safety of ketamine as a treatment for depression shows the risks of long-term ketamine treatment remain unclear.

Genes that regulate a cellular recycling system called autophagy are commonly mutated in Crohn's disease patients, though the link between biological housekeeping and inflammatory bowel disease remained a mystery.

Using the latest techniques, MRI can provide a 'one-stop-shop' method for evaluation of potential living liver donors, according to an article.

The smile may be the most common and flexible expression, used to reveal some emotions, cover others and manage social interactions that have kept communities secure and organized for millennia. But how do we tell one kind of smile from another?

A study by MIT researchers shows that collections of ultracold molecules can retain the information stored in them for hundreds of times longer than previously achieved in these materials. These clusters might thus serve as 'qubits,' the basic building blocks of quantum computers.

A human-made cousin of a small molecule found in olive oil can disrupt the hunger-signaling pathway, new research suggest.
