A new primate species, the Popa langur, has been discovered in central Myanmar, with only 200-250 individuals remaining due to habitat loss and hunting. Genetic analysis reveals it separated from known species around 1 million years ago.
A research team from the German Primate Center found that lemurs' average cognitive performance in tests was not fundamentally different from other primate species. Despite smaller brains, lemurs showed domain-specific cognitive skills similar to those of monkeys and great apes.
A study found that malaria drug chloroquine does not inhibit SARS-CoV-2 infection in human lung cells, raising concerns about its potential use as a COVID-19 treatment. The research highlights the importance of using relevant cell lines in clinical trials to ensure effective treatments.
Scientists have developed a gene therapy approach that reactivates visual circuitry in human retinas using near-infrared light, potentially restoring vision in blind patients. The treatment was tested on human retinas kept alive in culture medium and showed promising results.
A team of scientists used artificial intelligence to examine whether mandrills' facial features are a result of genetic similarity or selection. They found that half-sisters with the same father exhibit stronger facial resemblance, indicating a possible evolutionary mechanism for social discrimination and nepotism among kin.
Researchers identified the cleavage of furin as crucial for SARS-CoV-2 entry into host cells. The study also found potential starting points for therapy and live attenuated vaccines by exploring coronaviruses with similar activation sequences in animals, enabling the virus to spread in humans.
Researchers found that SARS-CoV-2 requires the protease TMPRSS2 to enter host cells, a target for therapeutic intervention. The drug camostat mesilate, approved for pancreatic inflammation, shows promise in blocking virus entry into lung cells.
Research on red titi monkeys reveals that female pair bond maintenance is driven by relationship management, while males provide useful services like offspring care and territory defense. The study supports the 'male-services hypothesis' suggesting females prioritize proximity to maintain relationships.
Researchers investigated primate societies' evolutionary paths and found pair living played a crucial role in transitioning from solitary life to complex societies. The study suggests that paternal care increased offspring survival, reinforcing pair living and paving the way for group living.
A study on olive baboons found that females avoid mating if either the male or female shows visible signs of infection, while males do not change their behavior. The researchers aim to understand how sexually transmitted diseases impact non-human primate populations.
A team of neuroscientists discovered that the brain combines visual features through high-frequency oscillations to achieve a unified percept. The researchers measured nerve cell activity in rhesus monkeys while performing a visual perception task, finding that faster responses occurred with stronger high-frequency oscillations.
Researchers found that males with similar personalities are more likely to form strong social bonds and cooperate in critical situations. The study suggests that personality homophily provides an evolutionary advantage by facilitating communication and coordination among friends.
Scientists have shown that monkeys disperse seeds from primary forests to secondary forests, leading to increased biodiversity. Over 20 years of study, researchers found that moustached and black-fronted tamarins were responsible for dispersing over 10% of the seeds, which germinated and survived for at least a year.
Researchers found that West African green monkeys quickly learned the meaning of unfamiliar drone sounds and mimicked an East African vervet monkey's call to warn against eagles. This suggests that alarm call structure is deeply rooted in evolutionary history.
Researchers reconstructed the phylogenetic tree of six African baboon species, revealing that genes were exchanged between species, leading to new species emergence. This study sheds light on fundamental biological processes producing new species and provides an analogous model for understanding human evolutionary history.
Researchers at German Primate Center found that MERS virus mutations make it more resistant to the human immune system. This could lead to a rise in severe cases and potentially trigger a pandemic.
Researchers identify medial prefrontal cortex as key player in perceptual memory, allowing for stable perception of environment despite intermittent blinks. This finding has implications for understanding interaction between perception and memory, and may also shed light on confidence in one's own perception.
Researchers from the German Primate Center found that visual attention desynchronizes nerve cell activity, enabling more complex information processing. This insight may provide evidence for mechanisms underlying ADHD and autism, and sheds light on how the brain processes stimuli.
The study highlights the devastating impact of human activities on primate populations, with up to 78% decline in their habitats by the end of the century. The authors recommend extending protected areas, reforestation, and promoting sustainable farming practices to conserve primates.
Researchers found that the primate brain quickly and efficiently shifts attention with each eye movement in a well-synchronized manner. This synchronization allows for optimal processing of relevant stimuli across saccades. The study's findings have implications for understanding disorders like schizophrenia and visual neglect.
Researchers at the German Primate Center have improved DNA transfer in gene therapy by modifying viruses to produce a protein called CD9, which increases exosome production and virus efficiency. This results in an 80% infection rate, making gene therapies more efficient.
Red-fronted lemurs demonstrate ability to differentiate between conspecifics and closely related sister species based on facial pattern and color variations. The study found that females showed a stronger reaction than males, indicating visual and olfactory signals play crucial role in species recognition.
Researchers propose hypothesis that prenatal stress affects offspring in two ways: early stages leading to slow growth and later stages leading to fast growth. Study across 21 mammal species supports this idea, predicting outcomes in offspring development and performance.
Researchers tested a new vaccination approach in rhesus monkeys, finding that the type and order of administration influenced immune activation. The study showed promise for inducing sustained protective immunity without increasing CD4+ T helper cells.
A study by Morel et al. found that physical effort in movements is not solely determined by force resistance but also by the duration of the movement. Additionally, the researchers identified common optimization principles in decision-making and motor control, suggesting a shared mechanism for both.
Researchers studied mandrill behavior in Gabon's rainforests, finding they avoid sick individuals through olfactory cues. This 'behavioral immune system' minimizes parasite transmission, influencing social behavior and co-evolution.
The study highlights the alarming rate of primate species extinction, with over half threatened due to human activities. Immediate action is needed to protect primates and their habitats through sustainable land-use initiatives and education.
