Magnetic Particles in Human Post Mortem Brains Mapped

Many living organisms, such as migratory birds, are thought to possess a magnetotactic sense, which enables them to respond to the Earth's magnetic field. Whether or not humans are capable of sensing magnetism is the subject of debate. However, several studies have already shown that one of the preconditions required for such a magnetic sensory system is indeed met: magnetic particles exist in the human brain.

The research team has systematically mapped the distribution of magnetic particles in human postmortem brains. Their findings were published in the journal Scientific Reports. 

Fight Against Pesticides: Marine Mammals lack Functional Gene

As marine mammals evolved to make water their primary habitat, they lost the ability to make a protein that defends humans and other land-dwelling mammals from the neurotoxic effects of a popular human-made pesticide. The implications of this discovery led researchers to call for monitoring our waterways to learn more about the impact of pesticides and agricultural run-off on marine mammals, such as dolphins, manatees, seals and whales.

Drug-Resistant Strains: Lower-risk Malaria Regions are Breeding Grounds

New drug-resistant strains of the parasite that causes malaria tend to evolve in regions with lower malaria risk; in areas with high transmission rates, they get outcompeted by the more common, drug-sensitive strains inside the human host. In high-transmission settings, it takes a long time for drug-resistant strains to take hold, but once they do, they can spread rapidly, according to a new study.

Economic and Political Aspects in Better Healthcare

Richer, perhaps, but certainly not very healthy. In 2016, life expectancy in India was 68.6 years, compared with 76.2 in China, 75.28 in Sri Lanka, 72.49 in Bangladesh, and 70.25 in Nepal. In 2015, the Bank says, 39.6% of Indians were at risk of catastrophic expenditure for surgery.  This is because 65% of the population had no insurance coverage and was spending out-of-pocket (OOP) for medical care.

Importance of Proper Nutrition to Young Athletes

To be in top condition for competition, young athletes need proper nutrition – even more than their older counterparts do. "Adolescence is the major growth time for everybody, but boys and girls participating in organized sports are depleting their bodies of energy and proteins and carbohydrates while their bodies are trying to grow, so it's kind of a double whammy for them," said Christopher Ina. 

Surveillance of Drug-resistant Tuberculosis with the New Method

Global tuberculosis control and elimination will require detailed real-time information on the location of individuals with the disease, the presence of drug resistance, and the patterns of transmission. The surveys currently used are only conducted periodically and are not sufficient to effectively control tuberculosis, which causes more than 4,500 deaths daily.
