Patients with drug-resistant malaria cured by plant therapy

When the standard malaria medications failed to help 18 critically ill patients, the attending physician in a Congo clinic acted under the ‘compassionate use’ doctrine and prescribed a not-yet-approved malaria therapy made only from the dried leaves of the Artemisia annua plant. In just five days, all 18 people fully recovered. This is a small but stunningly successful trial.

Photosynthesis in the dark? Unraveling the mystery of algae evolution

Researchers compared the photosynthetic regulation in glaucophytes with that in cyanobacteria, to elucidate the changes caused by symbiosis in the interaction between photosynthetic electron transfer and other metabolic pathways. Their findings suggest that cyanelles of the glaucophyte Cyanophora paradoxa retain many of the characteristics observed in their ancestral bacteria, and that C. paradoxa is the primary symbiotic algae most similar to cyanobacteria than other lineages of photosynthetic organisms in terms of metabolic interactions.

Novel method to detect toxic effects of chemicals could reduce need for animal testing

Traditional toxicological investigations performed on animals (in vivo) are expensive, time-consuming and may cause animal suffering. But new research demonstrates that a neuronal cell model, derived from mouse, can be used to evaluate the neurotoxic effect of chemicals. The alternative toxicity risk assessment could reduce reliance on animal testing while also enable quick large scale toxicity evaluations. …

Totally bizarre facts about the star-nosed mole

In a new synthesis of anatomy research, scientists showcase the surprising, record-breaking and just plain weird adaptations of the star-nosed mole. The animal eats faster and sports a more sensitive touch organ than any other mammal, is the first mammal known to smell underwater and offers fascinating insights about the brain-body interface. …

In experiments on Earth, testing possible building blocks of alien life

Extraterrestrial life, if it exists, could use different amino acid building blocks than living things here on Earth. To better understand what alien life might look like, researchers are studying which amino acids stand up to the types of extreme conditions found on other planets and moons. …

Atomic-level motion may drive bacteria’s ability to evade immune system defenses

A study has found evidence that extremely small changes in how atoms move in bacterial proteins can play a big role in how these microorganisms function and evolve traits, such as antibiotic resistance. …

Plant’s parent genes cooperate in shaping their child

Plant biologists discovered for the first time how factors arising from the mother and father in flowering plants cooperate to develop the shape of their child. Until now, it has been unknown whether paternal factors cooperate or conflict with each other to bring about zygote asymmetry. The outcome of this discovery is expected to shed light on the exact mechanism of plant body shape formation and possibly lead to the generation of new hybrid plants. …
