Why I'm Thinking About Alcohol Taxes
1hThis is an excerpt from The Atlantic 's climate newsletter, The Weekly Planet. Subscribe today . The climate scientist Ken Caldeira recently tweeted a joke meant to charm carbon-tax advocates. "If we don't want people to drink so much alcohol, rather than taxing alcohol, we can subsidize everything that is not alcohol," he wrote . His point, if I may ruin the punch line, is that the United States

We find that…
TBK1 and IKKϵ act like an OFF switch to limit NLRP3 inflammasome pathway activation [Immunology and Inflammation]
2hNACHT, LRR, and PYD domains–containing protein 3 (NLRP3) inflammasome activation is beneficial during infection and vaccination but, when uncontrolled, is detrimental and contributes to inflammation-driven pathologies. Hence, discovering endogenous mechanisms that regulate NLRP3 activation is important for disease interventions. Activation of NLRP3 is regulated at the transcriptional level and by.
Restoring fertility in yeast hybrids: Breeding and quantitative genetics of beneficial traits [Genetics]
2hHybrids between species can harbor a combination of beneficial traits from each parent and may exhibit hybrid vigor, more readily adapting to new harsher environments. Interspecies hybrids are also sterile and therefore an evolutionary dead end unless fertility is restored, usually via auto-polyploidisation events. In the Saccharomyces genus, hybrids are…
Therapeutic inhibition of USP9x-mediated Notch signaling in triple-negative breast cancer [Medical Sciences]
2hTriple-negative breast cancer (TNBC) is a breast cancer subtype that lacks targeted treatment options.

One water bucket to find them all: Detecting fish, mammals, and birds from a single sample
2hIn times of exacerbating biodiversity loss, reliable data on species occurrence are essential.

However, eDNA turns out to be capable of providing much more than fish occurrence data, including information on other vertebrates. A study demonstrates how
The vampire that doesn't suck blood: New parasite-host relationships in Amazonian candirus
2hScientists report a vampire fish attached to the body of an Amazonian thorny catfish. Very unusually, the candirus were attached close to the lateral bone plates, rather than the gills, where they are normally found. Since the hosts were not badly harmed, and the candirus apparently derived no food benefit, scientists believe this association is commensalistic rather than parasitic.
