Climate change likely caused migration, demise of ancient Indus Valley civilization

2018-11-13 18:41:32

More than 4,000 years ago, the Harappa culture thrived in the Indus River Valley of what is now modern Pakistan and northwestern India, where they built sophisticated cities, invented sewage systems that predated ancient Rome's, and engaged in long-distance trade with settlements in Mesopotamia. Yet by 1800 BCE, this advanced culture had abandoned their cities, moving instead to smaller villages in the Himalayan foothills. A new study from the Woods Hole Oceanographic Institution (WHOI) found evidence that climate change likely drove the Harappans to resettle far away from the floodplains of the Indus.

No pause in global warming in the past 100 years

2018-11-13 13:12:12

Global warming has been attributed to persistent increases in atmospheric greenhouse gasses (GHGs), especially in CO2, since 1870, the beginning of the Industrial Revolution. Nevertheless, the upward trend in global mean surface temperature (GMST) slowed or even paused during the first decade of the 21st century, even though CO2 levels continued to rise and reached nearly 400 ppm in 2013. This episode has typically been termed the global warming hiatus, or slowdown in warming. The hiatus is characterized as a near-zero trend over a certain period. The hiatus appeared during 2001-2013/2002-2012 with extremely weak interannual variability in some GMST sequences, and the slowdown in the others.

2018-11-13 12:16:52

About 140 years ago, Charles Darwin seemed to be bothered by evidence suggesting the sudden occurrence of numerous angiosperms in the mid-Cretaceous. Since Darwin's theory of evolution implies that all organisms should increase gradually, the sudden appearance of angiosperms would have represented a headache in his theory.

A magnetic method to control the transport of chiral Majorana fermions

2018-11-13 12:14:53

The Majorana fermion, a particle that is its own antiparticle, was originally introduced as a putative elementary particle by Ettore Majorana in 1937, and the chiral Majorana fermion was experimentally observed in topological superconductors in 2017. Since the Majorana fermion is a charge-neutral particle, the direct effect on Majorana fermions by electromagnetic methods should fail. Now, researchers have proposed a scheme to control the transport of chiral Majorana edge modes in a ring-shaped Josephson junction of a topological superconductor using magnetic flux.

How plants evolved to make ants their servants

2018-11-12 20:00:08

Plants are boring. They just sit there photosynthesizing while animals have all the fun. Right? Not so much. Take a look at the interactions between ants and plants—plants have evolved features specifically to make them enticing to ants, like juicy nectar for the insects to eat and hollow thorns for them to take shelter in. In exchange, plants use ants to spread their seeds and even act as bodyguards. A new study in the Proceedings of the National Academy of Sciences breaks down the genetic history of 1,700 species of ants and 10,000 plant genera, and the researchers found that the long history of ant and plant co-evolution started with ants foraging on plants and plants later responding by evolving ant-friendly traits.

Diverse biofeedstocks have high ethanol yields and offer biorefineries flexibility

2018-11-12 15:10:07

Biorefineries are picky eaters. They only consume one or two types of plant matter. Researchers processed and experimentally measured ethanol production from five different herbaceous feedstocks. They examined two annuals (corn stover and energy sorghum) along with three perennials (switchgrass, miscanthus, and restored prairie). They determined that a lignocellulosic ethanol refinery could use a range of plant types without having a major impact on the amount of ethanol produced per acre, or per land area.
