Researchers in Japan have genetically transferred a unique courtship behavior from one fruit fly species to another. By turning on a single gene in insulin-producing neurons, the team successfully made a species of fruit fly (Drosophila melanogaster) perform a gift-giving ritual it had never done before. The study, published in the journal Science, represents the…

In a new study led by Oxford University’s Department of Chemistry, chemists have demonstrated the synthesis of a cyclocarbon that is stable enough for spectroscopic characterisation in solution at room temperature. nough to be studied in liquid solution form at room temperature. The study – only the second example of a new type of molecular…

Researchers at Columbia Engineering have built a cancer therapy that makes bacteria and viruses work as a team. In a study published recently in Nature Biomedical Engineering, the Synthetic Biological Systems Lab shows how their system hides a virus inside a tumor-seeking bacterium, smuggles it past the immune system, and unleashes it inside cancerous tumors. The…

Data provided by the water satellite, a joint effort between NASA and the French space agency, is helping to improve tsunami forecast models, benefitting coastal communities. The SWOT (Surface Water and Ocean Topography) satellite captured the tsunami spawned by an 8.8 magnitude earthquake off the coast of Russia’s Kamchatka Peninsula on July 30, 11:25 a.m….

For the first time in more than thirty years, the heaviest nucleus decaying via proton emission has been measured. The previous similar breakthrough was achieved in 1996. The radioactive decay of atomic nuclei has been one of the keystones of nuclear physics since the beginning of nuclear research. Now the heaviest nucleus decaying via proton…

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…
