monkey : a nonhuman primate mammal with the exception usually of the lemurs and tarsiers; especially : any of the smaller longer-tailed catarrhine or platyrrhine primates as contrasted with the apes — Webster
Monkeys are haplorhine (“dry-nosed”) primates, a group generally possessing tails and consisting of about 260 known living species. There are two distinct lineages of monkeys: New World Monkeys and catarrhines. Apes emerged within the catarrhines with the Old World monkeys as a sister group, so cladistically they are monkeys as well. However, traditionally apes are not considered monkeys, rendering this grouping paraphyletic. The equivalent monophyletic clade are the simians. Many monkey species are tree-dwelling (arboreal), although there are species that live primarily on the ground, such as baboons. Most species are also active during the day (diurnal). Monkeys are generally considered to be intelligent, particularly Old World monkeys. — Wikipedia

- Dynamics of adaptive immunity in tuberculosis...on May 17, 2022 at 3:22 pm
A new study partially explains why tuberculosis infections easily take hold in the host's lungs and suggests that boosting T cell response is key to creating a therapy that can shut down the infection at its onset.
- Bolder marmoset monkeys learn faster than shy oneson May 9, 2022 at 3:20 pm
Individual traits seem to drive our learning success: for instance, conscientious individuals often show higher academic performance. A group of cognitive and behavioral biologists conducted personality assessments and a battery of learning tests with common marmosets and found that such a link, intertwined with family group membership, exists in these monkeys, too.
- Neuroscientists find multiple brain regions...on May 4, 2022 at 9:08 pm
Neurobiologists give new meaning to the term 'motor mouth'. By carefully mapping neural networks in marmoset and macaque monkeys, they determined that multiple areas in the brain's frontal lobe control the muscles of vocalization and could provide a foundation for complex speech.
- Smooth movements are achieved by the stable basal...on April 26, 2022 at 2:16 pm
Researchers have applied a chemogenetic tool in macaque monkeys and suppressed the subthalamic nucleus, a part of the basal ganglia circuitry. The chemogenetic suppression induced unstable movements. In the output nucleus of the basal ganglia, the internal pallidum, neurons showed no firing rate change, but their spike train became variable. The subthalamic nucleus may stabilize neural activity in the basal ganglia for smooth movements.
- 'I know this song!' Evolutionary keys to musical...on April 25, 2022 at 4:11 pm
When we hear a song that we already know, we can identify it even if it is not an exact version of the original. If it sounds higher or lower, faster or slower, or if the instruments are different from the known version, humans can identify it even if there are these superficial changes to the melody. New research explores the extent to which this skill is based on skills that are also present in other animals, i.e., not unique to humans.

- Developmental origin of the adrenal cortex in...on May 20, 2022 at 1:38 pm
Sitting atop each kidney and measuring only around two centimeters long, the adrenal glands are tiny but mighty. These glands produce steroid hormones, including those involved in stress response, blood pressure maintenance, and fertility. When their development goes awry, it can cause a life-threatening condition called primary adrenal insufficiency, also known as Addison's disease. Many of the genetics involved in this and other adrenal gland disorders remain unknown.

Humans behave in strange ways. We readily reveal our inner feelings during moments of weakness, which doesn't seem like the smart thing to do.
- Bolder marmoset monkeys learn faster than shy oneson May 9, 2022 at 4:59 pm
Individual traits seem to drive our learning success: for instance, conscientious individuals often show higher academic performance. A group of cognitive and behavioral biologists from University of Vienna conducted personality assessments and a battery of learning tests with common marmosets and found that such a link, intertwined with family group membership, exists in these monkeys, too. The study results were recently published in the journal Scientific Reports.
- Malaysia's 'mystery monkey' appears to be a...on May 6, 2022 at 2:22 pm
An international team of researchers has found evidence that suggests Malaysia's "mystery monkey" is a hybrid between a proboscis monkey and a silvery langur. In their paper published in the International Journal of Primatology, the group describes their analysis of pictures taken of the monkey and how they came to their assessment about its origins.
- First leaf fossil study of Borneo's rainforest...on April 28, 2022 at 7:00 pm
The first study of leaf fossils conducted in the nation of Brunei on the island of Borneo has revealed that the current dominant tree group, the dipterocarps, has dominated the rainforests for at least 4 million years, according to an international research team led by Penn State in partnership with Universiti Brunei Darussalam. The findings, published in the journal PeerJ, suggest that the current landscape is similar to what was present during the Pliocene Epoch, 5.3 to 2.6 million years […]
