You might not want to depend on your smartphone app alone to help you avoid or achieve pregnancy, say the authors of a new study. A review of nearly 100 fertility awareness apps finds that most don’t employ evidence-based methodology.
Parents and society shouldn’t shift the blame for young people’s sexual behavior on what teens supposedly see and read in the media about intimate encounters. So says a researcher who led a thorough systematic analysis of 22 relevant studies on … Continue reading
Scientists have developed an automated method for three-dimensional tracking of massive eruptions from the Sun, called Coronal Mass Ejections (CMEs). The Automated CME Triangulation (ACT) system uses data from three space-based observatories that orbit the Sun at different locations, allowing … Continue reading
Astronomers have released a catalog of the hidden universe, which reveals the unseen sources of energy found over the last 12 billion years of cosmic history.
Numerical models show hot, rocky exoplanets can change their chemistry by vaporizing rock-forming elements in steam atmospheres that are then partially lost to space.
Just when it seemed that missing cases of microcephaly in Colombia were straining the credibility of the Zika virus’ connection to the birth defects, the latest report from Colombia includes five new cases of microcephaly with Zika infections.
Planetary scientists have discovered pieces of opal in a meteorite found in Antarctica, a result that demonstrates that meteorites delivered water ice to asteroids early in the history of the solar system.
Stunning new images and the highest-resolution maps to date of Jupiter at thermal infrared wavelengths give a glowing view of Juno’s target, a week ahead of the NASA mission’s arrival at the giant planet. The maps reveal the present-day temperatures, … Continue reading
Sparrows form pair bonds that are normally monogamous, but many females are unfaithful to their partner and have offspring with other males. Biologists believe that the male birds are unfaithful to ensure they father as many chicks as they can, … Continue reading
Men think women with make-up on are more ‘prestigious’, while women think women who wear make-up are more ‘dominant,’ a psychology study has found.
With a surface resembling that of plants, solar cells improve light-harvesting and thus generate more power. Scientists reproduced the epidermal cells of rose petals that have particularly good antireflection properties and integrated the transparent replicas into an organic solar cell. … Continue reading
A tech start-up has invented a world-first multi-function antenna for laptops that fits into the extremely limited space of the hinge cavity.
There is merit in looking at the use of wearable biosensors to detect whether opioid users stay focused on their rehabilitation programs. This follows a preliminary study. Scientists tested the use of wristband sensors worn by a group of patients … Continue reading
Engineering graduate students, one of whom lost his hands to meningitis, design and build a foot-activated video game controller.
Space agencies examine the extent of greenhouse gases in the air via prisms and gratings in satellites. New technology now makes it possible to connect both components with each other so that they are suitable for space thus achieving a … Continue reading
