Honey is more effective and less harmful than usual care for improving symptoms of upper respiratory tract infections, particularly cough frequency and cough severity, according to a systematic review and meta-analysis of previous studies, published in the journal BMJ Evidence Based Medicine. Honey is more effective than usual care alternatives and avoids causing harm through antimicrobial resistance. Image credit: PollyDot. Upper respiratory tract...

A Somali sengi (Galegeeska revoilii) at the Assamo locality in Djibouti. As is observed in other sengi species, Somali sengis have some variation in pelage colors. These differences seem to correspond to the color variation of substrates between occurrence localities. At the Assamo site, in the extreme southeastern corner of Djibouti, sengi habitats are comprised of rocks with more rusty coloration than elsewhere in the country. Compared to other Djiboutian sites, sengis from Assamo have dorsal pelage hairs with more pronounced reds. Image credit: Steven Heritage.

An artist’s conception of a potential solar companion, which theorists believe was developed in the Sun’s birth cluster and later lost. If proven, the solar companion theory would provide additional credence to theories that the Oort Cloud formed as we see it today, and that Planet Nine was captured rather than formed in place.

Experimental set-up. Quartz-glass sample container cylinder is filled partially with superfluid 3He-B, leaving a free surface of the superfluid approximately 3 mm above the centre of the surrounding coil system. The space above the free surface is vacuum due to the vanishing vapor pressure of 3He at sub-millikelvin temperatures. Magnons can be trapped in this configuration in two separate locations, in the bulk (colored blue) and touching the free surface (colored red). Transverse NMR coils are used both for RF pumping of magnons into the BECs, and for recording the induced signal from the coherently precessing magnetization M (light yellow arrow). The amplitude of the recorded signal is proportional to βM, the tipping angle of M, and its frequency corresponds to the precession frequency of the condensate. The condensates are trapped by the combined effect of the distribution of the orbital anisotropy axis of the superfluid (green arrows) via spin-orbit coupling, and a minimum of the external magnetic field created using a pinch coil (magenta wire loop). The external field H is oriented along the z axis of the sample container. Image credit: Autti et al, doi: 10.1038/s41563-020-0780-y.

This artist’s impression shows ‘Oumuamua, the first interstellar object discovered in our Solar System. Recent observations show that the object is moving faster than predicted while leaving the Solar System. Astronomers assume that venting material from its surface due to solar heating is responsible for this behavior. This outgassing can be seen in this artist’s impression as a subtle cloud being ejected from the side of the object facing the Sun. Image credit: NASA / ESA / Hubble / ESO / M. Kornmesser.

NASA’s Viking 1 orbiter photographed the Cydonia region in the northern latitudes of Mars on July 25, 1976 while searching for a landing site for the Viking 2 lander. The speckled appearance of the image is due to missing data, called bit errors, caused by problems in transmission of the photographic data from Mars to Earth. Bit errors comprise part of one of the ‘eyes’ and ‘nostrils’ on the eroded rock that resembles a human face near the center of the image. Shadows in the rock formation give the illusion of a nose and mouth. Planetary geologists attribute the origin of the formation to purely natural processes. The feature is 1.5 km across, with the Sun angle at approximately 20 degrees. The picture was taken from a range of 1,873 km. Image credit: NASA / JPL.
