Here is where I walk : episodes from a life in the forest
\"While living in the Presidio National Park, Leslie Carol Roberts became enchanted with the park's 125-year old forest, native plant and habitat restoration, serpentinite rock formations, and wild beaches just outside the Golden Gate. Roberts unearths stories of scientists, spiritualists, and artists around the globe engaged with specific and peculiar places, from the Indiana Dunes to Tasmanian euc forests to the work of landscape painters, to Iowa classrooms -- in this memoir pursuing an understanding what it means to live a life of creativity and creation\"--Provided by publisher.

Nigeria hit by unprecedented Lassa fever outbreak
As efforts to contain it mount, researchers are racing to find out what is driving this year's surge in cases and deaths. In the first 2 months of this year, Nigeria has had more confirmed cases of Lassa fever, a hemorrhagic disease that kills 20% to 30% of those it sickens, than in any previous year. As of 11 March, the toll from this rodent-borne virus stood at 365 confirmed cases, 16 of those among vulnerable health care workers, and 114 deaths. And those figures are widely considered an underestimate. As the government and its international partners scramble to set up isolation wards and deliver protective gear to health workers, researchers on three continents are racing to figure out what is driving the unprecedented outbreak and what it portends for the future. Is it simply better disease surveillance in the wake of Ebola, the similar but more deadly disease that began its rampage across West Africa in 2014? Has the virus changed in some way? Are there more of the rats that carry it, or are more rats infected with it? Or is another rat capable of spreading the virus as well? Considering how lethal Lassa fever is, shockingly little is known about it, experts say.

9 Billion?
The population projections in these graphics compiled by Science can be considered best scientific guesses, not destiny. Still, they offer a window into what the world might look like in 2050. World population is expected to pass 7 billion in late October and is projected to top 9 billion by 2050; the latest U.N. projections put it at about 10 billion in 2100. But all population projections are uncertain, as they are entirely dependent on assumptions about the future—for instance, how many children a woman will have 20 or 30 years hence. In that sense, the numbers in these graphics compiled by Science can be considered best scientific guesses, not destiny. What's more, the further out one looks, the cloudier these projections become. Still, they offer a window into what the world might look like in 2050.

MALARIA WARS
Can malaria be eliminated from the Mekong region before multiple-drug resistance makes it untreatable? A disaster is looming in Cambodia and the rest of the Greater Mekong subregion: A deadly malaria parasite has become resistant to both drugs used in the so-called artemisinin combination therapy, raising the specter of untreatable malaria. Exactly how big the threat is, and whether and how it might sweep through the region and beyond, are uncertain. But no one is taking any chances. The only way to avert that crisis, says a growing chorus of malaria researchers, international agencies, and donors, is to eliminate malaria completely from the entire region—and that means wiping out every single parasite. But no one has ever eliminated the disease in a place as socially and epidemiologically complex as the Mekong, and it is not at all clear they can pull it off. The stakes are high.

In Vietnam, an anatomy of a measles outbreak
A mistrust of vaccines, an overburdened hospital, and even the weather conspired to kick off a devastating measles outbreak last year. Routine immunization is one of the great public health success stories in Vietnam, where rates of vaccine-preventable diseases have plummeted. But the measles outbreak last year was another story, with 60,000 reported cases and nearly 150 deaths in children under age 2. Experts trace the epidemic to the public's loss of faith in the government-led vaccination program, following reports of adverse events associated in time with another vaccine. Many parents stopped vaccinating their children, leaving them susceptible to measles. When the virus swept in from the north and hit Hanoi, it exploded. Panicked parents rushed their children to the hospital, which was quickly overburdened. With poor infection control, the hospital became a hub of measles transmission, and children who weren't already infected caught the virus there.

Skirmishing over the scope of the threat
As malaria experts chart their battle plans, they are looking to the past for clues. Since resistance to today's best malaria drug, artemisinin, was discovered in the Mekong region the late 2000s, experts have feared that it would follow the route of chloroquine, an earlier malaria drug, and sweep out of the Mekong region and into Africa, killing millions of children. But as scientists probe the current threat, they are finding that artemisinin resistance is a very different beast than its predecessor. In the Mekong, for instance, artemisinin resistance is not only spreading, as did chloroquine, but it is also emerging independently, dooming efforts to build a firewall around the region to contain it. Questions remain, but what is already abundantly clear is that very different strategies are needed to stop it.

MEASLES IS ON THE RISE - AND COVID-19 COULD MAKE IT WORSE
Many children in poor countries are lucky to get a single dose, however, which doesn't always lead to full protection in all who receive it. Because the virus is so contagious, 92-95% of a population needs to be fully immunized to ward off outbreaks. In Ukraine, after a child died of unrelated causes following a measles jab in 2008, vaccination coverage plummeted from 95% that year to 31% in 2016, says Robb Linkins, a measles specialist in the global immunization division at the US Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia. A new vaccine delivery system being developed by two teams - one a collaboration between the CDC and the Georgia Institute of Technology and Micron Biomedical, both in Atlanta, and the other at Vaxxas, a biotech company based in Sydney, Australia - could be a \"game changer\" for measles control, says Cochi. [...]the measles patch has languished for lack of funding, he says, and has yet to reach clinical trials. [...]polio is eradicated, the world does not have the appetite or money to target another disease for extinction, Cochi says.
