An interstellar comet that blazed past the sun last year could be nearly three times older than our solar system and is unlike anything ever seen before in our cosmic backyard, astronomers said Monday.
An international team of scientists led by Dr. Graciela Delvene of the Geological and Mining Institute of Spain (CSIC) has uncovered the oldest known evidence of maternal care in shellfish, revealing that some freshwater ...
Spoorti Gandhadmath carefully placed 3.5-inch (8.9-centimeter) pots on a shelf in a growth chamber. Within seven days of sowing, newly sprouted leaves had fully emerged from each of the carefully selected seeds, representing ...
Genes are not passed on exclusively from parents to their offspring. Some are mobile and can also jump to other species, as researchers at the Max Planck Institute for Marine Microbiology in Bremen have now shown. The direct ...
The group leading the charge in the search for extraterrestrial life has given the all clear: An interstellar comet looks to be completely natural and free of any alien tech.
A researcher at Kyushu University and his collaborators have shown that continuous parameters in quantum gravity may not be freely adjustable "dials" from outside the theory, but rather arise from operators within the theory ...
Aptamers are short DNA or RNA strands that can recognize and bind to a specific target molecule with high precision. Similar to antibodies, they can be used to detect these molecules or modulate their activity. Unlike antibodies, ...
Researchers reported this week a deadly outbreak of plague in Siberia 5,500 years ago, revealing that Yersinia pestis evolved lethal genetic traits far earlier than suspected. A drug developed for heart tissue repair may ...
Like humans, wildlife is increasingly vulnerable as climate change fuels longer and more intense heat waves, disrupting feeding and breeding and, in extreme cases, proving fatal.
New antibiotic candidates for drug-resistant bacteria may reside inside prions, misfolded proteins in the brain best known for rare and fatal degenerative brain diseases. Prion and prion-like proteins may hide short peptides, ...
