High-tech fishing gear could help save critically endangered right whales

Many fish, marine mammals and seabirds that inhabit the world's oceans are critically endangered, but few are as close to the brink as the North Atlantic right whale (Eubalaena glacialis). Only about 411 of these whales exist today, and at their current rate of decline, they could become extinct within our lifetimes.

Vaccine is a cost-effective solution for countries burdened by typhoid

Introducing a typhoid conjugate vaccine (TCV) into routine child vaccine schedules and conducting a catch-up campaign to vaccinate all children up to age 15 is a cost-effective solution for many low- to middle-income countries severely burdened by typhoid, a new study led by researchers at the Yale School of Public Health finds.

Evidence of new magnetic transitions in late-type dwarfs from Gaia DR2

Since the second Gaia data release on the 25th April 2018, astrophysicists have had at their disposal an unprecedented wealth of information not only on distances and motions of stars in the galaxy, but also on many other stellar parameters that came along by exploiting the instrumentation aboard the satellite and the unique characteristics of the mission. Multiple observations of the same star, required to derive its distance and motion, also produced parameters related to stellar variability. Data for stars with spots on the surface similar to those on our Sun, in particular, provide information on their rotation period and on their surface magnetic fields. Stellar spots generated by magnetic fields at the surface modulate the stellar brightness as it rotates, making it possible to derive the star's rotation period and to provide an indication of its magnetic activity. The large number of stars observed made it possible to produce, with just the first 22 months of Gaia observations, the largest dataset on rotation to date, with rotation period and modulation amplitude of some 150,000 solar-like stars.
