To investigate plants’ airborne sound emissions, Khait et al. constructed a reliable recording system, where each plant is recorded simultaneously by two microphones; first, they recorded plants within an acoustic box and developed machine learning algorithms to classify the recorded sounds; then they tested the system in a greenhouse, while monitoring physiological parameters of the recorded plants.

A large stream of meltwater (about 5 to 10 m in width) emerges from an upstream supraglacial lake in the Greenlandic ice on July, 21 2012. The darker shapes are minor streams covered by cryoconite (a mix of dust particles, soot, meteorite dust and organic material) which covers the ice sheet. Cracks cutting through the streams are visible. Along these cracks water can flow through, enlarging them and, eventually, generating moulins that can deliver meltwater through the ice.

ESA’s XMM-Newton X-ray observatory recorded 20 dust rings, 19 of which are shown here in arbitrary colors. The image merges observations made two and five days after GRB 221009A erupted. Dark stripes indicate gaps between the detectors. A detailed analysis shows that the widest ring visible here, comparable to the apparent size of a full Moon, came from dust clouds located about 1,300 light-years away. The innermost ring arose from dust at a distance of 61,000 light-years -- on the other side of our Galaxy. Image credit: ESA / XMM-Newton / M. Rigoselli, INAF.

Using an interventional study in healthy, normal-weight participants, Thanarajah et al. demonstrate that, independent of body weight gain and alterations in metabolic markers, exposure to high-fat/high-sugar food: (i) reduces preferences for low-fat food, (ii) plays a critical role in up-regulating brain responses to anticipation and consumption of highly palatable, energy-dense food, and (iii) has a generalized effect on the neuronal encoding of prediction errors in the context of associative learning and independent of food rewards. Taken together, repeated consumption of high-fat/high-sugar relative to isocaloric low-fat/low-sugar food, and in the absence of changes in body weight or metabolic state, can rewire brain circuits and thereby induce neurobehavioral adaptations. Hence, changing the food environment and reducing the availability of energy-dense high-fat/high-sugar food items is pivotal to combating the obesity pandemic.

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.
