Credit: Victor Baptista The development of small hydropower dams is widespread throughout Brazil and elsewhere in the world, vastly overshadowing large hydropower projects. The proliferation of these smaller dams is a response to growing energy and security needs. Their expansion, however, threatens many of the remaining free-flowing rivers and […]

Here’s how to watch the full ‘wolf moon’ this week

January’s full moon, popularly known as the wolf moon, is almost upon us. Here’s “howl” to watch it shine brightly this Thursday (Jan. 28). The moon will be at its fullest for just an instant — on Thursday, that happens at 2:16 p.m. EST (19:16 UTC). But, as with every full moon cycle, the moon […]

Purported phosphine on Venus more likely to be ordinary sulfur dioxide — ScienceDaily

In September, a team led by astronomers in the United Kingdom announced that they had detected the chemical phosphine in the thick clouds of Venus. The team’s reported detection, based on observations by two Earth-based radio telescopes, surprised many Venus experts. Earth’s atmosphere contains small amounts of phosphine, which may be produced by life. Phosphine […]

Trees That Live Fast, Die Young, and Mess with Climate Models

Under a business-as-usual scenario of greenhouse gas emissions, the average global temperature may increase by almost 5°C through the end of the century. This climate change could cause a 1-meter increase in sea levels, possibly wreaking havoc on coastal regions and demanding hundreds of billions of dollars every year in adaptation and mitigation […]

Schizophrenia is 2nd highest risk factor for dying of COVID-19, after age

Schizophrenia may be one of the highest risk factors for dying from COVID-19, second only to age, according to a new study.  Previous studies had found that people with mental illnesses, particularly depression and schizophrenia — a condition that causes distortions in thinking and perception — had a higher risk of becoming infected with SARS-CoV-2, […]

Diamond holds up at pressures more extreme than those in Earth’s core

Diamond

Diamond stands up to a squeeze. Surprisingly, the material’s structure persists even when compressed to 2 trillion pascals, more than five times the pressure in Earth’s core, scientists report January 27 in Nature. The study suggests that diamond is metastable at high pressures: It retains its structure despite the fact that other, more stable structures […]

Geological phenomenon widening the Atlantic Ocean — ScienceDaily

An upsurge of matter from deep beneath the Earth’s crust could be pushing the continents of North and South America further apart from Europe and Africa, new research has found. The plates attached to the Americas are moving apart from those attached to Europe and Africa by four centimetres per year. In between these continents […]
