Resistance to artemisinin, the main component of the current antimalarial treatments recommended by WHO, is already widespread in South-East Asia, but it had not previously been described in Africa. Scientists from the Institut Pasteur recently detected the emergence and spread of malaria parasites capable of resisting artemisinin derivatives for the first time in Rwanda.
A new iron intervention study has determined which of the world's low-and-middle income countries would benefit from using iron-containing micronutrient powders to tackle childhood anaemia.
Finding out if the food and water we consume are safe from toxic and carcinogenic metals can now be much faster and simpler. Researchers at the University Johannesburg developed an efficient and more sensitive method to test for dangerous levels of heavy metals, like arsenic, cadmium and chromium in vegetables and water. The method can be used to test other foods also. A clay-based adsorbent makes testing for several metals at the same time possible.
An early blood test could detect which babies deprived of oxygen at birth are at risk of serious neurodisabilities like cerebral palsy and epilepsy.
Despite recent reports of lower COVID-19 incidence among high-altitude populations, current data is insufficient to conclude that high altitude is protective against the SARS-CoV-2 virus.
A multidisciplinary team from The University of Texas Medical Branch at Galveston has uncovered a Zika virus mutation that may be responsible for the explosive viral transmission in 2015/2016 and for the cause of microcephaly (babies with small heads) born to infected pregnant women. The study is currently available in Proceedings of National Academy of Sciences.
Researchers at the National Institutes of Health and other institutions have discovered another set of pore-like holes, or channels, traversing the membrane-bound sac that encloses the deadliest malaria parasite as it infects red blood cells. The channels enable the transport of lipids--fat-like molecules--between the blood cell and parasite, Plasmodium falciparum. The parasite draws lipids from the cell to sustain its growth and may also secrete other types of lipids to hijack cell functions to meet its needs.
Compounds tested for their potential as antibiotics have demonstrated promising activity against one of the deadliest infectious diseases - tuberculosis (TB).
Modifying 12 risk factors over the lifecourse could delay or prevent 40% of dementia cases, according to an update to The Lancet Commission on dementia prevention, intervention, and care, which is being presented at the Alzheimer's Association International Conference (AAIC 2020).
