A recent study suggests that humanity's response to climate change could do more harm than the changes itself. The research highlights the devastating impact of human activities on tropical forests and biodiversity. To mitigate this damage, experts emphasize the importance of planning and adopting sustainable practices.
Research reveals human Chlamydia pneumoniae originated from an animal source, specifically amphibians like frogs, and has adapted to infect humans. The study's findings emphasize the need for improved diagnostic tests, precautions, and vaccine development to combat this respiratory disease.
Researchers found striking relationships between language demographics and grammatical complexity. Languages with larger populations tend to have simpler pronoun and number systems. The study proposes the Linguistic Niche Hypothesis, where languages evolve within socio-demographic niches.
Researchers have characterised a new multi-drug resistant strain of Salmonella Typhimurium causing life-threatening disease in Africa. The new strain, ST313, is resistant to several antibiotics and may spread from person to person, predominantly affecting individuals with weakened immune systems.
Researchers at Stanford University have found evidence that adaptation is a major driver of human genomic evolution. The study, published online in Public Library of Science Genetics, reveals that genetic mutations beneficial to an organism's environment are more common than previously thought. This suggests that humans have undergone ...
Scientists have discovered how bird flu adapts in patients, offering a new way to monitor the disease and prevent a pandemic. The research found specific mutations in the virus that may allow it to adapt to humans, indicating a potential risk of a pandemic.
A new scientific journal uses evolutionary biology to tackle pressing issues such as climate change, food safety, and infectious diseases. The journal features articles that discuss topics ranging from adapting to elevated atmospheric carbon dioxide to predicting the extinction of certain populations due to human-mediated stresses.
Fossilized remains of small-bodied humans found in Palau, Micronesia, share characteristics with Homo sapiens and H. floresiensis, but not all features match. The discovery provides insight into the process of island dwarfism in human populations.
Researchers found that Mycobacterium indicus pranii (MIP) is the earliest ancestor of generalist mycobacterial pathogens, including Crohn's disease pathogen M. avium paratuberculosis (MAP). The study suggests that MIP and MAP descended from a common ancestor and infected marine organisms before arriving on soil through bird-droppings.
A study by Cardiff University scientists suggests that human activities such as deforestation and poaching are driving the decline of the giant panda population. The research finds that conservation efforts should focus on habitat restoration and protection to ensure the species' survival.
Scientists at St. Jude Children's Research Hospital have found specific mutations that distinguish influenza viruses in birds from those that infect humans. These markers can be used to track changes in H5N1 avian influenza strains threatening humans, suggesting potential adaptation and spread.
Researchers found that police officers who use eye contact are more effective at calming down hysterical citizens. The study analyzed over 35 hours of police-citizen interactions and found that regulating gaze is central to face-to-face interaction in these situations.
A review in the Journal of Internal Medicine estimates that 50 million people acquired zoonotic diseases between 2000 and 2005, resulting in up to 78,000 deaths. The Dengue virus and Japanese Encephalitis Virus are among the most common zoonotic killers.
Biomedical engineers at Washington University in St. Louis have discovered a new learning strategy called categorical adaptation, which suggests that learning does not necessarily scale proportionally with error size.
A new study by St. Jude Children's Research Hospital has shown a DNA-based vaccine to be highly effective in protecting mice against lethal challenges with the H5N1 avian influenza virus. The vaccine targets two conserved viral proteins and one variable protein, providing complete protection in mice.
Researchers found that gut bacterium B. theta adapts its genome in response to changing nutrient conditions, allowing it to maintain stability of the gut's complex microbial society. The study reveals that this adaptability is crucial for maintaining intestinal health and preventing diseases such as obesity and diabetes.
