The Influence of Supergenes on the Evolutionary Process

Biology, Science /

Locking together beneficial traits, supergenes confer significant evolutionary advantages. However, this association comes with potential costs, as it becomes exceedingly challenging to eliminate detrimental mutations. Traditionally, it has been believed that sexual reproduction evolved as a means for organisms to mix or recombine different alleles (gene variations) in the next generation, creating essential genetic variation […]

AI-Enhanced Catheter for Medication-Free UTI Prevention

Biology, Biotechnology, Healthcare /

A 3D-printed catheter creates a miniature obstacle course to thwart microbes, addressing widespread infections in hospital settings. Over 100 million people globally need a urinary catheter annually, which is crucial post-surgery. Yet, around one quarter in developing nations and about an eighth in the U.S. who use them may experience catheter-associated urinary tract infections (CAUTI)

Giant pandas Use a ‘Facebook’-like Social Network to Communicate

Biology, Science /

Researchers have found that giant pandas, traditionally believed to be solitary and antisocial creatures, actually engage in a surprisingly active social life, resembling the way individuals share updates on Facebook. This discovery provides a new perspective on the social behavior of these elusive bears. However, in a study conducted in China’s Wolong Nature Reserve, researchers

Scientists are Close to Creating a Male Birth Control Pill. Will Men Embrace it?

Biology, Medical Care, Medicine, Pharmacy, Science Education /

Researchers in the United Kingdom are currently testing the first male contraceptive pill. This raises the question of whether men are willing to actively participate or if they prefer women to continue shouldering the entire burden of deciding when and whether to reproduce. Historically, women have borne the predominant burden of preventing pregnancy, often resorting

The Oldest Mosquito Fossils Reveal that Male Mosquitoes Fed on Blood

Biology, Science /

The preserved specimens of amber display distinct mouthparts that are currently found only in female individuals A mosquito is probably female if you swat it on your arm or neck. Only female mosquitoes feed on blood, providing the protein they need to develop eggs. Males consume plant fluids and nectar as females’ skin-piercing mouthparts are

Apes can Identify Friends they Haven’t Encountered for Decades

Biology, Science, Zoology /

Apes outshine many of us as they promptly recognize family and friends even after a gap of over two decades, marking the longest-recorded “social memory” in a non-human species. Providing crucial understanding of the evolution of human social recognition, the Johns Hopkins University study originated from the observation that apes appeared to recognize humans they

Electric Eel Shocks Transfer Genes to Nearby Animals

Biology, Genetics /

A recent investigation indicates that the electrical discharge from an electric eel is potent enough to facilitate the transfer of genetic material from the surroundings into the cells of neighboring animals. In laboratory conditions, electroporation refers to applying an electric field to cells to enhance the permeability of their cell membrane. This enables the introduction
