A better understanding of crop yields under climate change
Researchers use satellites to measure soil moisture around certain crops to solve a long-standing mystery about how water impacts agricultural production. The researchers found that models using soil moisture explain 30% to 120% more of the year-to-yea…
Nearly one in 10 in the US reports having depression
Increases in depression without commensurate increases in treatment are widespread, reports a study. In 2020, past 12-month depression was prevalent among nearly 1 in 10 Americans and almost 1 in 5 adolescents and young adults.
Rheumatoid arthritis drug effective against myasthenia
Early intervention with rituximab, a drug used in the treatment of rheumatoid arthritis (RA), can reduce the risk of deterioration in myasthenia gravis, an autoimmune disease that causes loss of muscle control.
COVID-19 took serious toll on Native Hawaiian/Pacific Islander mental and physical health
Native Hawaiians/Pacific Islanders, or NH/PIs, comprising more than 20 ethnic groups hailing from Polynesia, Micronesia, and Melanesia, are understudied despite being the third fastest growing racial group in the United States. Two studies now report t…
Melanoma treatment: Potential target bypasses therapeutic resistance to immune checkpoint blockers
Over the last decade, immune checkpoint blockers, or ICBs, have revolutionized treatment for various advanced cancers, including melanoma, the most aggressive skin cancer that was considered largely incurable not long ago. However, three-fourths of adv…
Geologist proposes the number of ancient Martian lakes might have been dramatically underestimated by scientists
Though Mars is a frozen desert today, scientists have shown that Mars contains evidence of ancient lakes that existed billions of years ago, which could contain evidence for ancient life and climate conditions on the red planet. Through a meta-analysis…
Three new species of ground snakes discovered under graveyards and churches in Ecuador
Scientists have discovered three new cryptozoic (living underground) snakes hidden under graveyards and churches in remote towns in the Andes of Ecuador. The new snakes, which are small, cylindrical, and rather archaic-looking, were named in honor of i…
Diabetes: When circadian lipid rhythms go wrong
Like all living beings, human physiological processes are influenced by circadian rhythms. The disruption of our internal clocks due to an increasingly unbalanced lifestyle is directly linked to the explosion in cases of type 2 diabetes. By what mechan…
A smartphone’s camera and flash could help people measure blood oxygen levels at home
In a proof-of-principle study, researchers have shown that smartphones are capable of detecting blood oxygen saturation levels down to 70%. This is the lowest value that pulse oximeters should be able to measure, as recommended by the U.S. Food and Dru…
How stressed tumor cells escape cell death: New mechanism discovered
Because of their highly active metabolism, many tumors are susceptible to a special type of cell death, ferroptosis. Nevertheless, cancer cells often manage to escape this fate. Scientists have now discovered a new mechanism by which normal as well as …
Development defect in macrophages causes lung disease
New discovery on the causes of PAP lung disease can also offer solutions for treating obesity and heart disease. The research group has identified a genetic defect that causes the accumulation of lipids in the pulmonary alveoli.
