Two days after touching down on asteroid Bennu, NASA's OSIRIS-REx mission team received on Thursday, Oct. 22, images that confirm the spacecraft has collected more than enough material to meet one of its main mission requirements -- acquiring at least 2 ounces (60 grams) of the asteroid's surface material.
Scientists have devised a method for mapping in unprecedented detail the thickets of slippery sugar molecules that help shield HIV from the immune system. Mapping these shields will give researchers a more complete understanding of why antibodies react to some spots on the virus but not others, and may shape the design of new vaccines that target the most vulnerable sites on viruses.
A 'safety net' made up of multiple ambitious and interlinked goals is needed to tackle nature's alarming decline, according to an international team of researchers analyzing the new goals for biodiversity being drafted by the UN's Convention on Biological Diversity (CBD).
New radio images from ALMA show for the first time the direct effect of volcanic activity on the atmosphere of Jupiter's moon Io.
New research shows that high levels of microplastics (MPs) are released from infant-feeding bottles (IFBs) during formula preparation. The research also indicates a strong relationship between heat and MP release, such that warmer liquids (formula or water used to sterilize bottles) result in far greater release of MPs. The work underlines the need for appropriate mitigation strategies and new plastic technologies.
Scientists demonstrated the first use of a method called self-calibration to remove contamination from gravitational lensing signals. The results should lead to more accurate cosmological models of the universe.
The lessons learned from a near infrared absorbing, bowl-shaped molecule made only from hydrogen and carbon atoms offers insights for future organic conductors.
Researchers have been able to create optical framed knots in the laboratory that could potentially be applied in modern technologies. Their work opens the door to new methods of distributing secret cryptographic keys - used to encrypt and decrypt data, ensure secure communication and protect private information.
Researchers found that bacteria essential to ripening cheese can sense and respond to compounds produced by fungi in the rind and released into the air, enhancing the growth of some species of bacteria over others. The make-up of the cheese microbiome is critical to flavor and quality of the cheese.
