A NASA-funded study analyzed urban growth among 30 mid-sized cities using Landsat satellite data, revealing three common spatial patterns of land development. The research provides current global assessments of urbanization, including growth in Africa, and highlights the need for updated maps to inform climate modeling and social scien...
The world's population will grow to 8.9 billion by 2050, with slower growth in richer countries and more urbanization in underdeveloped nations. The average population density is expected to rise from 45 people per square kilometer to 66 people per square kilometer.
A study found that selective hunting of male saiga antelopes for their horns is driving the species closer to extinction. The sex ratio has become severely imbalanced, with females outnumbering males by a ratio of 100:1, leading to reproductive collapse and population decline.
A recent study reveals significant discrepancies in shark fin trade reports, with estimates suggesting under-reporting of 24-49% compared to Hong Kong's quantities. The study highlights the need for continued monitoring and analysis in key seafood trading centers like Hong Kong.
Global analysis reveals 46% of the Earth's land surface is still intact wilderness, but only 2.4% of the world's population inhabits it. The areas are under threat from encroaching agriculture and resource extraction, with only 7% enjoying protection.
The Antioquian population in Colombia exhibits a high degree of European genetic influence, predominantly from southern Spain. This is reflected in the Y chromosome data, which show that 94% of males are of European descent.
A new study published at the CINP meeting found that treating patients with schizophrenia with Risperdal resulted in a daily savings of $2.80 US per patient, corresponding to an annual saving of $1,022 US. This cost-effectiveness analysis may translate into significant figures given the high prevalence of schizophrenia worldwide.
Dr. Yoav Horn founded the West Bank Cancer Program in 1978, helping to establish two oncology treatment centers and train Palestinian physicians. The program improved early cancer treatment and saved lives, according to data from a computerized registry of over 7,000 patient records.
