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.

Nuclear magnetic resonance (NMR) is a powerful tool that is widely used in many scientific fields‚ from analytical chemistry to medical diagnostics. However‚ regardless of its widespread use‚ there are still areas in which this very informative method cannot be employed because it is limited by its low sensitivity.

Atmospheric aerosol particles exert a strong net cooling effect on the climate by making clouds brighter and more extensive‚ reflecting more sunlight back out to space. However‚ how aerosol particles form in the atmosphere remains poorly understood‚ especially in polar and marine regions.

Not all discoveries turn out to be actual new discoveries. This was the case for the extremely red objects (EROs) found in James Webb Space Telescope (JWST) data. Analysis shows that they are very similar to blue-excess dust obscured galaxies (BluDOGs) already reported in Subaru Telescope data.

Patients struggling with some chronic diseases often must wait years for a proper diagnosis. For example‚ symptoms such as shortness of breath can be attributed to many pulmonary as well as cardiovascular disorders‚ so patients may be treated for a misdiagnosed disease that is far from accurate diagnosis and treatment.
