Making the Invisible Visible: The Remarkable Journey of a Powerhouse Space Microscope

In the International Space Station's Destiny laboratory, NASA astronaut Dan Burbank, Expedition 30 commander, conducts a session with the Preliminary Advanced Colloids Experiment (PACE) at the Light Microscopy Module (LMM) in the Fluids Integrated Rack / Fluids Combustion Facility (FIR/FCF). PACE is designed to investigate the capability of conducting high magnification colloid experiments...

Mites that mate on our faces at night face extinction threat

Study of tiny parasites points to gene loss from adaptation putting them on dead-end evolutionary courseGliding through grease, and protected by our pores, tiny Demodex folliculorum mites lead a secretive life within our skin, only emerging at night to mate on our foreheads, noses and nipples. Successful as these sexual encounters are, their days as independent parasites may be numbered.The first...

How humans evolved to get along (to extent that we do)

The research shows that four neighboring groups of bonobos they studied at the Kokolopori Bonobo Reserve in the Democratic Republic of Congo maintained exclusive and stable social and spatial borders between them, showing they are indeed part of distinct social groups that interact regularly and peacefully with each other.

Attitudes around older motherhood too often emphasize risk and pregnancy timing

A political science professor argues that much of the official language around older motherhood is rooted in both ageism and ableism, as well as being out of step with current childbirth trends. The average age of childbirth has been rising steadily since the mid-1960s, and in some countries, more women are giving birth between the ages of 35 to 39 than between 20 and 24. But societal expectations...

Collecting a library of bee genomes

The USDA Agricultural Research Service is leading a project dubbed "Beenome100" to produce high-quality maps of the genomes of at least 100 bee species, capturing the diversity of bees in the United States, representing each of the major bee taxonomic groups in this country.

Researchers develop a low-background neutron detector array

A research team from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS), together with their collaborators from Sichuan University and Chinese Institute of Atomic Energy, has recently developed a high-efficiency low-background neutron detector array, which is essential for the precise cross-section measurement of the 13C(α,n)16O reaction at stellar energies in China...
