Astronomers from the Harvard–Smithsonian Center for Astrophysics (CfA) and elsewhere‚ report the discovery of a new 'warm Jupiter' exoplanet orbiting a rapidly rotating F-type star. The newfound alien world‚ designated TOI-4641 b could be nearly four times as massive as Jupiter. The finding was detailed in a paper published December 7 on the pre-print server arXiv.

A team of researchers led by Professor Young S. Park at UNIST's Department of Chemistry has achieved a significant breakthrough in the field of organic semiconductors. Their successful synthesis and characterization of a novel molecule called "BNBN anthracene" has opened up new possibilities for the development of advanced electronic devices.

A pair of veterinary medicine researchers at Medical University of Vienna and University of Vienna‚ in Austria‚ has found that some captive Goffin's cockatoos prefer to dunk their hard bread before eating it‚ seemingly as a means to improve its texture. In their paper published in the journal Biology Letters‚ Jeroen Zewald and Alice Auersperg‚ describe their observations of the birds and their theories on why the birds dunk the bread.

A research group has reported on a new method to enhance the electrochemical surface area (ECSA) in a calcium-doped perovskite‚ La0.6Ca0.4MnO3 (LCMO64)‚ thereby overcoming a common bottleneck in the application of perovskite oxides as electrocatalysts in hydrogen fuel cells.

Compound leaves‚ which are composed of multiple independent units called leaflets‚ show a wide diversity of patterning‚ ranging from trifoliolate‚ palmate‚ pinnate to higher ordered forms. There is agreement that the proximodistal expression patterns of morphogenetic regulators are associated with the compound leaf patterning. However‚ the mechanisms by which such patterns are established‚ maintained‚ and regulated‚ as well as their functional relationships to the sequential progression of leaflet formation are largely unknown.

A team of astronomers has used asteroseismology‚ or the study of stellar oscillations‚ to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and checked the measurements taken during the Gaia mission to study the near universe.

Using optogenetics‚ Würzburg researchers have detected a new acid sensor in plant cells that addresses a cell-internal calcium store. The study is published in the journal Science.

To an everyday consumer‚ the best gadgets on the market have the highest speed‚ the largest memory‚ and the longest battery life. Chasing this demand‚ the forefront of research often only considers these tangible performance metrics when innovating and designing next-generation electronics. In the wake of this technological stampede‚ the long-term environmental impacts lie obscured and neglected under the dust.

A research team at the Hong Kong University of Science and Technology (HKUST) has outlined the high-resolution structure of a little-known virus‚ improving our understanding of viral infection‚ which could pave the way for more accurate predictions of climate change.

A study published today (Dec. 15) in the journal Astronomy &; Astrophysics reveals the discovery of two new planetary systems orbiting stars similar to our sun‚ also known as solar analogs.
