Deforestation’s Hidden Toll: Impact on Child Health

Posted by in categories: biological, climatology, economics, education, health, sustainability

Do the impacts of deforestation go beyond the environment? What about human health, specifically the health of children? This is what a recent study published in Economics & Human Biology hopes to address as Dr. Gabriel Fuentes Cordoba, who is an associate professor of economics from Sophia University in Japan, investigated how deforestation in Cambodia effects the health of children around the time of their birth. This study holds the potential to help scientists, conservationists, and the public better understand the health effects of deforestation, specifically with the increasing effects of climate change around the world.

For the study, Dr. Fuentes Cordoba analyzed data obtained from the Cambodian Demographic Health Surveys and forest loss to ascertain the health impacts for pregnant women and children under five years of age who reside in areas of deforestation. In the end, Dr. Fuentes Cordoba discover alarming results that suggest deforestation exposure to women less than one year before pregnancy could lead to development of anemia, which is a precursor to malaria. This could result in significant health impacts on children being born, specifically reductions in birth weight, along with overall height and weight as they age.

“This research shows a negative impact of deforestation on child health,” Dr. Fuentes Cordoba said in a statement. “This negative impact may persist into adulthood and affect other aspects of wellbeing such as education acquisition and even wages. My findings indicate that future research should explore this aspect further.”

What math tells us about social dilemmas

Posted by in categories: economics, mathematics

Human coexistence depends on cooperation. Individuals have different motivations and reasons to collaborate, resulting in social dilemmas, such as the well-known prisoner’s dilemma. Scientists from the Chatterjee group at the Institute of Science and Technology Austria (ISTA) now present a new mathematical principle that helps to understand the cooperation of individuals with different characteristics. The results, published in PNAS, can be applied to economics or behavioral studies.

A group of neighbors shares a driveway. Following a heavy snowstorm, the entire driveway is covered in snow, requiring clearance for daily activities. The neighbors have to collaborate. If they all put on their down jackets, grab their snow shovels, and start digging, the road will be free in a very short amount of time. If only one or a few of them take the initiative, the task becomes more time-consuming and labor-intensive. Assuming nobody does it, the driveway will stay covered in snow. How can the neighbors overcome this dilemma and cooperate in their shared interests?

Scientists in the Chatterjee group at the Institute of Science and Technology Austria (ISTA) deal with cooperative questions like that on a regular basis. They use to lay the mathematical foundation for decision-making in such social dilemmas.

Legendary shipwreck’s treasure of “incalculable value” will be recovered by underwater robot, Colombia says

Posted by in categories: economics, government, robotics/AI

Colombia’s government on Friday announced an expedition to remove items of “incalculable value” from the wreck of the legendary San Jose galleon, which sank in 1708 while laden with gold, silver and emeralds estimated to be worth billions of dollars. The 316-year-old wreck, often called the “holy grail” of shipwrecks, has been controversial, because it is both an archaeological and economic treasure.

Culture Minister Juan David Correa told AFP that more than eight years after the discovery of the wreck off Colombia’s coast, an underwater robot would be sent to recover some of its bounty.

Recycling fertilizers from human excreta exhibit high nitrogen fertilizer value and result in low uptake of pharmaceutical compounds

Year 2023 face_with_colon_three


Recycling nutrients is essential for closing nutrient loops within a circular economy. Using locally available resources such as human excreta to produce bio-based recycling fertilizers can substitute mineral fertilizers and thereby promote environmentally friendly food production. To better understand the fertilizer potential and nitrogen value of human excreta, three novel and safe recycling products were evaluated in a field experiment. Two nitrified urine fertilizers (NUFs) and one fecal compost were applied alone or in combination, and compared against the commercial organic fertilizer vinasse. In addition, the uptake of pharmaceuticals was assessed for treatments with compost application. White cabbage (Brassica oleracea var. capitata f. alba) was cultivated in plots in three different soil types (sand, loam or silt) treated with the fertilizers according to plant needs and mineral soil nitrogen content. The two NUFs resulted in marketable yields similar to those of vinasse in all soil types. Combining fecal compost with a NUF led to increased marketable yield compared to compost alone. The highest yield was recorded from the sandy soil, where vinasse and NUF treatments led to comparable yields, as expected in organic productions systems (up to 72 t ha−1). The cabbage yield and total aboveground fresh biomass followed the following trend in all soils: NUFs ∼ vinasse ≥ compost + NUF ≥ compost. Nitrogen uptake in the cabbage heads and total biomass was significantly higher in sand (69.5–144 kg ha−1) than loam (71.4–95.8 kg ha−1). All compost treatments alleviated the effect of soil type and resulted in comparable nitrogen uptake and yield in all soil types. Plant uptake of pharmaceuticals (Carbamazepin) was higher in sand than in loam, and concentration in the edible part was lower than in the outer leaves. In conclusion, NUF alone appears to be a promising successful fertilizer substitute in horticultural food production. The combined application of NUF and compost led to slightly lower crop yields, but may increase soil carbon content in the long term, promoting climate-friendly food production.

In view of a growing world population and the human alteration of nutrient cycles, including nitrogen (N) and phosphorus ℗ (Rockström et al., 2009), transforming food production is a major challenge of this century (Springmann et al., 2018). Both N and P are essential nutrients for healthy plant growth in crop production; however, their addition to synthetic fertilizers is currently organized in a linear economy. The Haber-Bosch process, used to generate plant-available N from its airborne unreactive form, is energy intensive, depending on fossil fuels such as natural gas, and associated with high greenhouse gas emissions (Wang et al., 2021). P is obtained from finite, depleting phosphate rock resources and its mining is increasingly more expensive and polluting (Desmidt et al., 2015). This background emphasize the need for significant improvements of nutrient management in agriculture and for alternative, circular N and P sources to achieve global food security (Gerten et al.

More than 60% of Americans are living paycheck to paycheck. Here’s what researchers say is to blame

Posted by in categories: economics, robotics/AI, transhumanism

Along with climbing homelessness and other societal woes globally this is the time for transhuman ideals to emerge to save lives. We could automate all work and get universal basic income with AI to work for us.


About 61% of Americans are living paycheck to paycheck, an issue that impacts both low-wage and high-income families alike, according to new research from LendingClub.

Low-wage earners are most likely to live paycheck to paycheck, with almost 8 in 10 consumers earning less than $50,000 a year unable to cover their future bills until their next paycheck arrives. Yet even 4 in 10 high-income Americans, or those earning more than $100,000, say they’re in the same position, the research found.

Electrification or hydrogen? Both have distinct roles in the European energy transition

Posted by in categories: climatology, economics, sustainability

A study, published in One Earth, is the first to analyze the interplay of electrification and hydrogen in EU climate neutrality scenarios at greater sectoral detail. The analysis shows higher potential for electrification and identifies a more confined deployment range for hydrogen-based energy than earlier studies.

“Previous research has shown that our power system can be transformed to renewable sources like wind and solar at low cost and low environmental impact. However, the next question is how this renewable electricity can be used to substitute in the buildings, industry and transport sectors. Our analysis shows that the direct use of electricity, for example, via and , is critical for a broad range of sectors, while the conversion of electricity to hydrogen is important only for few applications,” says Felix Schreyer, PIK scientist and lead author of the study.

Using the energy-economy model REMIND, PIK-scientists investigated plausible combinations of both strategies in EU energy system transformation pathways under different scenario assumptions.

Nova-C Launch: A New Chapter in Lunar Exploration Begins

Posted by in categories: economics, space

No American spacecraft has made a soft landing on the Moon since NASA’s Apollo 17 in 1972, but that could change soon as the Intuitive Machines’ Nova-C lander launched from the historic Launch Complex 39A at NASA’s Kennedy Space Center at 1:05 am EST (10:05 pm PST) last night. With a currently scheduled landing date of February 22, Nova-C (also called IM-1 Odysseus) is slated to land in Malapert-A crater, which is approximately 190 miles (300 kilometers) from the Moon’s south pole. This landing will also mark the first time a private company will perform a soft landing on the Moon and holds the potential to test technologies that could be used on future human missions with NASA’s Artemis program.

“NASA scientific instruments are on their way to the Moon – a giant leap for humanity as we prepare to return to the lunar surface for the first time in more than half a century,” NASA Administrator Bill Nelson said in a statement. “These daring Moon deliveries will not only conduct new science at the Moon, but they are supporting a growing commercial space economy while showing the strength of American technology and innovation. We have so much to learn through CLPS flights that will help us shape the future of human exploration for the Artemis Generation.”

The science instruments that will be traveling with Nova-C include the Lunar Node 1 Navigation Demonstrator, Laser Retroreflector Array, Navigation Doppler Lidar for Precise Velocity and Range Sensing, Radio Frequency Mass Gauge, Radio-wave Observations at the Lunar Surface of the Photoelectron Sheath, and Stereo Cameras for Lunar Plume-Surface Studies. All these instruments are designed to investigate how spacecraft can both land and operate on the lunar surface, specifically near the south pole of the Moon.
