A drought lasting 13 years and several others that each lasted over three years may have contributed to the collapse of the Classic Maya civilization, chemical fingerprints from a stalagmite in a Mexican cave have revealed. A detailed analysis of oxygen isotopes in the stalagmite allowed a team of researchers, led by the University of…

A proposed earthquake early warning system could have provided several communities an alert of 10 seconds or more ahead of strong shaking from the magnitude 7.3 quake that occurred south of Sand Point near the tip of the Alaska Peninsula in mid-July. That analysis is provided by Alex Fozkos of the Alaska Earthquake Center’s systems…

White sharks exhibit stark differences between the DNA in their nuclei and the DNA in their mitochondria. Until now, scientists have pointed to the migration patterns of great whites to explain these differences. Scientists tested this theory in a new study by analyzing genetic differences between global white shark populations. In doing so, they discovered…

A research team from the Institut de Ciències del Mar (ICM-CSIC) has published a study in Communications Biology showing how ocean acidification and warming — two of the main consequences of global climate change — can simultaneously affect the structure, mineral composition, and microbiome of bryozoans, colonial invertebrates crucial for forming marine habitats. The findings…

Just as overlapping ripples on a pond can amplify or cancel each other out, waves of many kinds — including light, sound and atomic vibrations — can interfere with one another. At the quantum level, this kind of interference powers high-precision sensors and could be harnessed for quantum computing. In a new study published in…

Research from scientists at University of California San Diego School of Medicine have shed new light on an age-old question: what makes the human brain unique? The team’s discovery comes from their investigation of human-accelerated regions (HARs) — sections of the human genome that have accumulated an unusually high level of mutations as humans have…
