Resistance to antimalarial drugs is thought to result mainly from changes in the parasite’s genome. However, P. falciparum can also develop resistance to some antimalarial compounds by epigenetic changes, according to a new study led by ISGlobal, an institution supported by “la Caixa,” and the Institute of Tropical Medicine (ITM), Antwerp. This is of concern…
Researchers have proposed a new idea that may explain why some Antarctic icebergs are tinged emerald green rather than the normal blue, potentially solving a decades-long scientific mystery. Pure ice is blue because ice absorbs more red light than blue light. Most icebergs appear white or blue when floating in seawater, but since the early…
Optical clocks of the National Institute of Information and Communications Technology (NICT, Japan) and LNE-SYRTE (Systemes de Reference Temps-Espace, Observatoire de Paris, Universite PSL, CNRS, Sorbonne Universite, France) evaluated the latest “one second” tick of the International Atomic Time (TAI) and provided these data to the Bureau International des Poids et Mesures (BIPM) to be…
People exposed to trauma are less able to suppress unwanted emotional memories due to neural and behavioral disruptions in their brain that may contribute to the development of post-traumatic stress disorder (PTSD). PTSD is characterized by intense reliving of the trauma that is repetitive, intrusive and incapacitating. The intrusive nature of these hallmark symptoms suggests…
Our brain comprises 85 billion nerve cells and just as many so-called glial cells, which work in close contact with the former to guarantee their proper function. All originate from brain stem cells. But what decides when and how many of them become neurons or glial cells? A new study led by the Laboratory of…
As far back as Ancient Greece, a sculptured physique has been heralded as the pinnacle of physical perfection. But now, researchers from Japan have found that increased muscle mass doesn’t just make you look good, it could literally save your life. In a study published in Scientific Reports, researchers from Osaka University have revealed that…
New research from the NIHR Guy’s and St Thomas’ Biomedical Research Centre has found a way to predict rejection of a kidney transplant before it happens, by monitoring the immune system of transplant patients. The researchers have found that a signature combination of seven immune genes in blood samples can predict rejection earlier than current…
Each year in the United States, more than 600,000 children are seen in emergency rooms due to traumatic brain injury, a disruption to the normal function of the brain caused by a bump, blow or jolt to the head. Severe TBI results in approximately 7,000 childhood deaths annually, while survivors of the condition may suffer…
Heart attack patients taken directly to heart centres for lifesaving treatment have better long-term survival than those transferred from another hospital, reports a large observational study presented today at Acute Cardiovascular Care 20191 a European Society of Cardiology (ESC) congress. Directly admitted patients were older, suggesting that heart attacks in young adults, and particularly women,…
Women call an ambulance for husbands, fathers and brothers with heart attack symptoms but not for themselves. “It’s time for women take care of themselves too” is the main message of two studies from the Polish Registry of Acute Coronary Syndromes (PL-ACS) presented today at Acute Cardiovascular Care 20191,2 a European Society of Cardiology (ESC)…
