The intracellular purple sulfur bacterium ‘Candidatus Thiodictyon intracellulare’ has lost the ability to oxidize sulfur and now supplies a ciliate with energy from photosynthesis.

Climate reconstruction of the last 200,000 years from East Africa illustrates the living conditions of Homo sapiens when they migrated out of Africa / Homo sapiens was mobile across regions during wet phases and retreated to high altitudes during dry p…

Does evolution explain why we can’t resist a salty chip? Researchers found that differences between the elemental composition of foods and the elemental needs of animals can explain the development of pleasing tastes like salty, umami and sweet.

Engineers have demonstrated how, when the TMDC materials they make are stacked in a particular geometry, the interaction that occurs between particles gives researchers more control over the devices’ properties. Specifically, the interaction between el…

Investigators built a model to examine the potential impact of implementing blood pressure control programs at barbershops nationwide and found that such programs could reach one in three Black men with uncontrolled blood pressure nationally.

Fearsome and powerful, hurricanes can wreak massive destruction when they hit land. But while most hurricanes then weaken, others can strengthen again into extratropical cyclones and caused further damage inland. Now, researchers have used simulations …

Theorists simulate the molecular transitions that take place inside a furnace to create 2D molybdenum disulfide, a semiconductor that could find a home in next-generation electronics.

An observation of an insect exoskeleton on a potted plant may lead to the identification of a new species of cicada.

A new species of large prehistoric croc that roamed southeast Queensland’s waterways millions of years ago has been documented.

Researchers performed microtomography experiments the BL20XU beamline of the SPring-8 synchrotron radiation facility and found that brain capillary structures show a correlation with their neuron structures.

Inspired by kirigami, the Japanese art of folding and cutting paper, engineers have designed a new type of stent that could be used to deliver drugs to the gastrointestinal tract, respiratory tract, or other tubular organs in the body.

A new non-contact laser imaging system developed by engineering researchers, is designed to detect telltale signs of major blinding diseases in retinal blood and tissue that typically go unseen until it is too late.

A new study not only sheds light on how the APOE4 gene may cause some of the pathologies associated with Alzheimer’s disease, but also suggests a new treatment target that might help people who carry the APOE4 gene in early and late stages of the disea…

Scientists explore how protein and signaling pathways change in patients with Alzheimer’s disease. Their work creates a new model of disease progression, taking advantage of the heterogeneity that is inherent to human studies.

Researchers invented a more efficient device for doubling the frequency of incoming light by combining period reflectors inside a microcavity containing gallium nitride. This work may help in the construction of a deep UV light source with bactericidal…

Biologists sought to understand the impact of uneven distribution of eyespots on butterflies. The team found that the location of these eyespots is key to their protective function.

A team of scientists has shown that the healing of skin blisters is driven by hair follicle stem cells, which delay their own development in the process.

Artemisone is a promising substance in the fight against malaria. However, the active ingredient has yet to be used due its instability and because it is not easily absorbed by the body. A team has now pushed this a bit further. They have developed a v…

Researchers tracking the evolution of different strains of the plant pathogen that caused the Irish potato famine in the 1840s show that the historic lineage called FAM-1 was found in nearly three-fourths of the 140 historic and modern samples tested a…

Not only the 11-year cycle, but also all other periodic solar activity fluctuations can be clocked by planetary attractive forces. With new model calculations, they are proposing a comprehensive explanation of known sun cycles for the first time. They …
