The ocean is our planet’s largest life-support system. It stabilizes climate; stores carbon; produces oxygen; nurtures biodiversity; directly supports human well-being through food, mineral, and energy resources; and provides cultural and recreational services. The value of the ocean economy speaks to its importance: The Organization for Economic Cooperation and Development...

The biological carbon pump (BCP) comprises wide-ranging processes that set carbon supply, consumption, and storage in the oceans’ interior. It is becoming increasingly evident that small changes in the efficiency of the BCP can significantly alter ocean carbon sequestration and, thus, atmospheric CO2 and climate, as well as the functioning...

An exceptionally well-preserved specimen of the articulated rhodophyte Permocalculus, compared with P. tenellus sensu Elliott, 1955, is described from fine-grained Upper Permian limestones of the Khuff Formation of Saudi Arabia. Longitudinal medullary and sheaf-like cortical filaments extend through the uniserial series of elongate-globular, concave- and convex-terminating, interlocking segments for which they are interpreted to have functioned in articulation. The filaments tend to splay and branch laterally into the cortex where they terminate at the pores. At the terminal aperture, the filaments extend as bifurcating and possibly trifurcating branches and may serve as the origin of a new segment. Numerous elongate-globular chambers, up to five in each row and intimately involved with the filaments, are developed in the outer medulla and are considered to represent reproductive sporangia. The specimen is considered to have occupied predominantly low-energy, normal to slightly elevated salinity, shallow conditions within the subtidal regime of a lagoon.

Assemblages of upper lower through upper Miocene Discoaster spp. have been quantified from Integrated Ocean Drilling Program (IODP) Site U1338 in the eastern equatorial Pacific Ocean. These assemblages can be grouped into five broad morphological categories: six-rayed with bifurcated ray tips, six-rayed with large central areas, six-rayed with pointed ray tips, five-rayed with bifurcated ray tips and five-rayed with pointed ray tips. Discoaster deflandrei dominates the assemblages prior to 15.8 Ma. The decline in abundance of D. deflandrei close to the early–middle Miocene boundary occurs together with the evolution of the D. variabilis group, including D. signus and D. exilis. Six-rayed discoasters having large central areas become a prominent member of the assemblages for a 400 ka interval in the late middle Miocene. Five- and six-rayed forms having pointed tips become prominent in the early late Miocene and show a strong antiphasing relationship with the D. variabilis group. Discoaster bellus completely dominates the Discoaster assemblages for a 400 ka interval in the middle late Miocene. Abundances of all discoasters, or discoasters at the species level, show only (surprisingly) weak correlations to carbonate contents or oxygen and carbon isotopes of bulk sediment when calculated over the entire sample interval.

The comparative efficacy of ceftazidime-avibactam and meropenem-vaborbactam for treatment of carbapenem-resistant Enterobacteriaceae (CRE) infections remains unknown. This was a multicenter, retrospective cohort study of adults with CRE infections who received ceftazidime-avibactam or meropenem-vaborbactam for ≥72 hours from February 2015 to October 2018. Patients with a localized urinary tract infection and repeat study drug exposures after the first episode were excluded. The primary endpoint was clinical success compared between treatment groups. Secondary endpoints included 30- and 90-day mortality, adverse events (AE), 90-day CRE infection recurrence, and development of resistance in patients with recurrent infection. A post hoc subgroup analysis was completed comparing patients who received ceftazidime-avibactam monotherapy, ceftazidime-avibactam combination therapy, and meropenem-vaborbactam monotherapy. A total of 131 patients were included (ceftazidime-avibactam, n = 105; meropenem-vaborbactam, n = 26), 40% of whom had bacteremia. No significant difference in clinical success was observed between groups (62% versus 69%; P = 0.49). Patients in the ceftazidime-avibactam arm received combination therapy more often than patients in the meropenem-vaborbactam arm (61% versus 15%; P < 0.01). No difference in 30- and 90-day mortality resulted, and rates of AE were similar between groups. In patients with recurrent infection, development of resistance occurred in three patients that received ceftazidime-avibactam monotherapy and in no patients in the meropenem-vaborbactam arm. Clinical success was similar between patients receiving ceftazidime-avibactam and meropenem-vaborbactam for treatment of CRE infections, despite ceftazidime-avibactam being used more often as a combination therapy. Development of resistance was more common with ceftazidime-avibactam monotherapy.

Security council had spent weeks seeking resolution but Trump administration opposed mention of organizationThe US has blocked a vote on a UN security council resolution calling for a global ceasefire during the Covid-19 pandemic, because the Trump administration objected to an indirect reference to the World Health Organization.The security council has been wrangling for more than six weeks over the resolution, which was intended to demonstrate global support for the call for a ceasefire by the UN secretary general, António Guterres. The main source for the delay was the US refusal to endorse a resolution that urged support for the WHO’s operations during the coronavirus pandemic.Donald Trump has blamed the WHO for the pandemic, claiming (without any supporting evidence) that it withheld information in the early days of the outbreak.China insisted that the resolution should include mention and endorsement of the WHO.On Thursday night, French diplomats thought they had engineered a compromise in which the resolution would mention UN “specialized health agencies” (an indirect, if clear, reference to the WHO).The Russian mission signaled that it wanted a clause calling for the lifting of sanctions that affected the delivery of medical supplies, a reference to US punitive measures imposed on Iran and Venezuela. However, most security council diplomats believed Moscow would withdraw the objection or abstain in a vote rather than risk isolation as the sole veto on the ceasefire resolution.On Thursday night, it appeared that the compromise resolution had the support of the US mission, but on Friday morning, that position switched and the US “broke silence” on the resolution, raising objection to the phrase “specialist health agencies”, and blocking movement towards a vote.“We understood that there was an agreement on this thing but it seems that they changed their mind,” a western security council diplomat said.“Obviously they have changed their mind within the American system so that wording is still not good enough for them,” another diplomat close to the discussions said. “It might be that they just need a bit more time to settle it amongst themselves, or it might be that someone very high up has made a decision they don’t want it, and therefore it won’t happen. It is unclear at this moment, which one it is.”A spokesperson for the US mission at the UN suggested that if the resolution was to mention the work of the WHO, it would have to include critical language about how China and the WHO have handled the pandemic.“In our view, the council should either proceed with a resolution limited to support for a ceasefire, or a broadened resolution that fully addresses the need for renewed member state commitment to transparency and accountability in the context of Covid-19. Transparency and reliable data are essential to helping the world combat this ongoing pandemic, and the next one,” the spokesperson said.While the force of the resolution would be primarily symbolic, it would have been symbolism at a crucial moment. Since Guterres made his call for a global ceasefire, armed factions in more than a dozen countries had observed a temporary truce. The absence of a resolution from the world’s most powerful nations, however, undermines the secretary general’s clout in his efforts to maintain those fragile ceasefires.Talks will continue next week at the security council to explore whether some other way around the impasse can be found.
