’s graduate-student survey say that they would most like to work in academia — down from 56% in 2019, whenlast surveyed PhD students. Those who want to pursue careers outside academia point to reasons including lack of funding, stiff competition for jobs and lack of work–life balance.

Global luxury sales set to hit record this year, study saysLuxury spending is growing faster than ever, fueled by pent-up pandemic demand and shifting demographics as younger, more diverse consumers buy into tiny handbag and post-streetwear trends. Yall got to get it together. Either we are on the brink of a recession or people are rich and throwin down on handbags. The media is trash.

A First Look into the Nature of JWST/MIRI 7.7 micron Sources from SMACS 0723Until now, our knowledge of the extragalactic Universe at mid-IR wavelengths (| 5 microns) was limited to rare active galactic nuclei (AGN) and the brightest normal galaxies up to z~3. The advent of the JWST with its Mid-Infrared Instrument (MIRI) will revolutionise the ability of the mid-IR regime as a key wavelength domain to probe the high-z Universe. In this work we present a first study of JWST MIRI 7.7 micron sources selected with | 3 sigma significance from the lensing cluster field SMACS J0723.3-7327. We model their spectral energy distribution fitting with 13 JWST and HST broad bands, in order to obtain photometric redshifts and derived physical parameters for all these sources. We find that this 7.7 micron galaxy sample is mainly composed of normal galaxies up to z=4 and has a tail of about 2% of sources at higher redshifts to z~ 9-10. The vast majority of our galaxies have [3.6]-[7.7]|0 colours and very few of them need high dust extinction values (A_V=3 -6 mag) for their SED fitting. The resulting lensing-corrected stellar masses span the range 10^7-10^{11} Msun. Overall, our results clearly show that the first MIRI 7.7 micron observations of deep fields are already useful to probe the high-redshift Universe and suggest that the deeper 7.7 micron observations to be available very soon will open up, for the first time, the epoch of reionisation at mid-IR wavelengths.

The supply of multiple ecosystem services requires biodiversity across spatial scales - Nature Ecology & EvolutionThe authors test whether spatial scale (plot, local and landscape) affects the supply of various ecosystem services in grasslands, finding that some services are predicted by plot-level properties while others depend more on landscape-level management.
