Published Combining maths with music leads to higher scores, suggests review of 50 years of research
(via sciencedaily.com) Original source Children do better at maths when music is a key part of their lessons, an analysis of almost 50 years of research on the topic has revealed.
Published Evaluating cybersecurity methods
(via sciencedaily.com) Original source Researchers created a generic framework that enables an engineer or scientist to evaluate the effectiveness of defense schemes that seek to limit a hacker's ability to learn secret information by observing the behavior of a victim computer program.
Published How urea may have been the gateway to life
(via sciencedaily.com) Original source Urea reacts extremely quickly under the conditions that existed when our planet was newly formed. This new insight furthers our understanding of how life on Earth might have begun.
Published There may be good news about the oceans in a globally warmed world
(via sciencedaily.com) Original source An analysis of oxygen levels in Earth's oceans may provide some rare, good news about the health of the seas in a future, globally warmed world. A study analyzing ocean sediment shows that ocean oxygen levels in a key area were higher during the Miocene warm period, some 16 million years ago when the Earth's temperature was hotter than it is today.
Published This self-driving boat maps underwater terrain
(via sciencedaily.com) Original source Engineers concoct an easier way for scientists to study underwater topography.
Published Freely available risk model for hurricanes, tropical cyclones
(via sciencedaily.com) Original source As human-driven climate change amplifies natural disasters, hurricanes and typhoons stand to increase in intensity. Until now, there existed very few freely available computer models designed to estimate the economic costs of such events, but a team of researchers has recently announced the completion of an open-source model that stands to help countries with high tropical cyclone risks better calculate just how much those storms will impact their people and their economies.
Published What math can teach us about standing up to bullies
(via sciencedaily.com) Original source New research from Dartmouth takes a fresh look at game theory to show that being uncooperative can help people on the weaker side of a power dynamic achieve a more equal outcome -- and even inflict some loss on their abusive counterpart. The findings can be applied to help equalize the balance of power in labor negotiations, international relations and everyday interactions, as well as integrate cooperation into interconnected AI systems such as driverless cars.
Published Humans' ancestors survived the asteroid impact that killed the dinosaurs
(via sciencedaily.com) Original source A Cretaceous origin for placental mammals, the group that includes humans, dogs and bats, has been revealed by in-depth analysis of the fossil record, showing they co-existed with dinosaurs for a short time before the dinosaurs went extinct.
Published Research in a place where geological processes happen before your eyes
(via sciencedaily.com) Original source Taiwan experiences some of the world's fastest rates of mountain building -- they are growing at a faster rate than our fingernails grow in a year. The mountains also see frequent and significant earthquakes, the region experiences about four typhoons per year on average, and in some places, it receives upwards of several meters of rain annually.
Published Study of Earth's stratosphere reduces uncertainty in future climate change
(via sciencedaily.com) Original source New research reduces uncertainty in future climate change linked to the stratosphere, with important implications for life on Earth. A significant source of uncertainty relates to future changes to water vapor in the stratosphere, an extremely dry region of the atmosphere 15--50 km above the Earth's surface. Future increases in water vapor here risk amplifying climate change and slowing down the recovery of the ozone layer, which protects life on Earth from harmful solar ultraviolet radiation.
Published Study of deep-sea corals reveals ocean currents have not fuelled rise in atmospheric carbon dioxide
(via sciencedaily.com) Original source Pioneering analysis of deep-sea corals has overturned the idea that ocean currents contributed to increasing global levels of carbon dioxide in the air over the past 11,000 years.
Published Investing in nature improves equity, boosts economy
(via sciencedaily.com) Original source A new study shows that current trends in environmental degradation will lead to large economic losses in the coming decades, hitting the poorest countries hardest. But there is hope: investing in nature can turn those losses into gains.
Published How coral reefs can survive climate change
(via sciencedaily.com) Original source Similar to the expeditions of a hundred or two hundred years ago, the Tara Pacific expedition lasted over two years. The goal: to research the conditions for life and survival of corals. The ship crossed the entire Pacific Ocean, assembling the largest genetic inventory conducted in any marine system to date. The team's 70 scientists from eight countries took around 58,000 samples from the hundred coral reefs studied.
Published New nationwide modeling points to widespread racial disparities in urban heat stress
(via sciencedaily.com) Original source Using a combination of satellite data and modeling to study the temperatures and humidity people might feel in urban areas, researchers have pinpointed who in the U.S. is most vulnerable to heat stress.
Published 21st century economic growth will be slower than we thought
(via sciencedaily.com) Original source The global economy will grow slower in the 21st century than economists have expected, a finding that has implications for our ability to adapt to climate change in the coming decades, according to new research.
Published Lessons in sustainability, evolution and human adaptation -- courtesy of the Holocene
(via sciencedaily.com) Original source The El Gigante rockshelter in western Honduras is among only a handful of archaeological sites in the Americas that contain well-preserved botanical remains spanning the last 11,000 years. Considered one of the most important archaeological sites discovered in Central America in the last 40 years, El Gigante was recently nominated as a UNESCO World Heritage site.
Published Effect of volcanic eruptions significantly underestimated in climate projections
(via sciencedaily.com) Original source Researchers have found that the cooling effect that volcanic eruptions have on Earth's surface temperature is likely underestimated by a factor of two, and potentially as much as a factor of four, in standard climate projections.
Published Sinking seamount offers clues to slow motion earthquakes
(via sciencedaily.com) Original source The first ever 3D seismic imaging of a subducting seamount shows a previously unknown sediment trail in Earth's crust off the coast of New Zealand. Scientists think the sediment patches help release tectonic pressure gradually in slow slip earthquakes instead of violent tremors. The findings will help researchers search for similar patterns at other subduction zones like Cascadia in the U.S. Pacific Northwest.
Published Traditional methods cannot give us the insights we need to understand changing ecosystems
(via sciencedaily.com) Original source If we want to face up to the challenges posed by climate change and other global environmental changes, we need to bring complexity science into the mix with ecology and biodiversity conservation.
Published Conservation policies risk damaging global biodiversity, researchers argue
(via sciencedaily.com) Original source Rewilding, organic farming and the 'nature friendly farming' measures included in some government conservation policies risk worsening the global biodiversity crisis by reducing how much food is produced in a region, driving up food imports and increasing environmental damage overseas.
