Early-onset El NiƱo means warmer winters in East Asia, and vice versa      (via sciencedaily.com)     Original source 

Researchers have found that the early onset of El Nino around June leads to warm winter climates in Japan, while the late onset of El Nino is associated with colder winters. By analyzing 100-ensemble member climate simulations over the past 61 years, the team found that the warming of the tropical Indian Ocean was a player in warmer Japanese winters.

Mighty floods of the Nile River during warmer and wetter climates      (via sciencedaily.com)     Original source 

Global warming as well as recent droughts and floods threaten large populations along the Nile Valley. Sediment cores off the Nile mouth reveal insights into the effects and causes of heavy rainfall episodes about 9,000 years ago. That will help to prepare for weather extremes in a changing climate.

Nuclear spectroscopy breakthrough could rewrite the fundamental constants of nature      (via sciencedaily.com)     Original source 

Raising the energy state of an atom's nucleus using a laser, or exciting it, would enable development of the most accurate atomic clocks ever to exist. This has been hard to do because electrons, which surround the nucleus, react easily with light, increasing the amount of light needed to reach the nucleus. By causing the electrons to bond with fluorine in a transparent crystal, UCLA physicists have finally succeeded in exciting the neutrons in a thorium atom's nucleus using a moderate amount of laser light. This accomplishment means that measurements of time, gravity and other fields that are currently performed using atomic electrons can be made with orders of magnitude higher accuracy.

Exploring the chemical space of the exposome: How far have we gone?      (via sciencedaily.com)     Original source 

Scientists have taken on the daunting challenge of mapping all the chemicals around us. They take inventory of the available science and conclude that currently a real pro-active chemical management is not feasible. To really get a grip on the vast and expanding chemical universe, they advocate the use of machine learning and AI, complementing existing strategies for detecting and identifying all molecules we are exposed to.

Melting of Alaskan glaciers accelerating faster than previously thought      (via sciencedaily.com)     Original source 

Melting of glaciers in a major Alaskan icefield has accelerated and could reach an irreversible tipping point earlier than previously thought. The research found that glacier loss on Juneau Icefield, which straddles the boundary between Alaska and British Columbia, Canada, has increased dramatically since 2010. The team looked at records going back to 1770 and identified three distinct periods in how icefield volume changed. In particular, they found that icefield-wide, rates of glacier area shrinkage were five times faster from 2015-2019 relative to 1948-1979. The research team say that current published projections for the Juneau icefield may need to be updated to reflect the processes detailed in this latest study.

Dampening the 'seeds' of hurricanes      (via sciencedaily.com)     Original source 

Increased atmospheric moisture may alter critical weather patterns over Africa, making it more difficult for the predecessors of many Atlantic hurricanes to form, according to a new study.

Shrinking glaciers: Microscopic fungi enhance soil carbon storage in new landscapes created by shrinking Arctic glaciers      (via sciencedaily.com)     Original source 

Shrinking glaciers expose new land in the Arctic, creating unique ecosystems. Researchers studied how microbes colonize these barren landscapes. The study reveals a crucial role for specific fungal species in capturing and storing carbon in the newly formed soil. These findings suggest fungi are essential for future carbon storage in the Arctic as glaciers continue to recede.

The evidence is mounting: humans were responsible for the extinction of large mammals      (via sciencedaily.com)     Original source 

Human hunting, not climate change, played a decisive role in the extinction of large mammals over the last 50,000 years. This conclusion comes from researchers who reviewed over 300 scientific articles from many different fields of research.

Novel spectroscopy technique sheds light on NOx reduction      (via sciencedaily.com)     Original source 

The process that can convert pollution into benign by-products is called selective catalytic reduction, or SCR. Until now, it has been unclear how this reaction actually occurs, and contradictions have long existed between reaction models within the literature. Catalysis researchers used a technology called modulation excitation spectroscopy, or MES, to finally identify the correct pathway.

How researchers are using digital city-building games to shape the future      (via sciencedaily.com)     Original source 

Researchers have come up with exciting and sophisticated new mapping technology enabling future generations to get involved in creating their own future built landscape. They say that planners are missing a real trick when it comes to encouraging and involving the public to help shape their own towns, cities and counties for the future. They also say that games platforms can be used to plan future cities and also help the public immerse themselves in these future worlds.
