New Tfr cell model uncovers molecular switches that restrain antibody responses

For the immune system to effectively combat pathogens, antibody responses must be precisely controlled. So-called follicular regulatory T cells (Tfr cells) play a key role in this process by limiting excessive immune responses and helping to maintain immune tolerance. Researchers at the University Hospital Bonn (UKB) and the University of Bonn have now developed a robust laboratory method that allows Tfr cells to be generated from precursor cells and studied in a targeted manner. The results were recently published in the journal Cellular & Molecular Immunology.

Treating knowledge as a conservation asset to resolve present-future biodiversity trade-offs

Conservation planning must allocate limited resources under substantial uncertainty about species interactions. A central dilemma is whether prioritization should be guided by phylogenetic diversity (PD), which preserves long-term evolutionary potential, or functional diversity (FD), which supports current ecosystem functioning. Because PD and FD are often weakly correlated, fixed prioritization schemes can misallocate effort when ecological information is incomplete. We develop a dynamic allocation framework in which the conservation objective is fixed, but the biodiversity proxy guiding decisions adapts to the level of interaction knowledge. When interaction information is limited, PD-based rankings are more robust to uncertainty; as interaction knowledge accumulates, rankings based on FD become increasingly reliable. We evaluate this framework using a 148-year Northeast Atlantic fish stomach time series and simulations on synthetic food webs. Across both empirical and simulated ecosystems, the adaptive strategy consistently produces higher post- disturbance diversity than fixed-weight PD–FD strategies and no-intervention baselines. This indicates that the PD–FD trade-off should be conditioned on the prevailing level of ecological knowledge, rather than fixed ex ante.

If you could drive a car straight up into the sky at highway speed, you would reach the edge of outer space in under an hour — the only thing protecting every living creature on Earth from the lethal vacuum is a layer of air thinner, relative to the planet, than the s - Space Daily

Get in a car. Point it at the sky. Drive at the speed limit. You would reach the official boundary of outer space — the line at which Earth’s atmosphere thins to the point where conventional aircraft can no longer generate enough lift to fly, and at which orb…
