Ancient genetic mutation helps explain origin of some human organs
A genetic mutation that occurred over 700 million years ago may have contributed to the development of certain organs in human beings and other vertebrates. This change, a random error in the evolutionary process, facilitated the connection of the gene networks involved in animal embryogenesis. www.sciencedaily.com/releas...

Reductions in individual plant growth sometimes boost community resilience
In sports, sometimes a player has to take one for the team. The same appears to be true in the plant world, where reduced individual growth can benefit the broader community. www.sciencedaily.com/releas...

That Feeling in Your Bones
Rainy weather has long been blamed for achy joints and back pain. Past research has yielded mixed results. New analysis tracking visits to the doctor with daily rainfall found no relationship between the two. www.sciencedaily.com/releas...

First proper motions measured of stars in a small galaxy outside the Milky Way
By combining data from the Hubble Space Telescope and the Gaia mission, astronomers have been able to measure the proper motion of 15 stars in the Sculptor Galaxy, the first such measurement outside the Milky Way. Analysis shows an unexpected preference in the direction of movement, which suggests that the standard theoretical models used to describe the motion of stars and dark matter halos in other galaxies might be invalid. www.sciencedaily.com/releas...

Geophysicists uncover new evidence for an alternative style of plate tectonics
Scientists have determined that a volcano and mountain plateau across Turkey formed not by the collision of tectonic plates, but by a massive detachment of plate material beneath Earth's surface. They propose that uplift of the Central Anatolian Plateau over 10 million years was caused by a dripping of the deep lithosphere. It first formed an above-ground basin which sprang up when the weight below broke off and sank into the depths of the mantle. www.sciencedaily.com/releas...

MUSE probes uncharted depths of Hubble Ultra Deep Field
Astronomers using the MUSE instrument on ESO's Very Large Telescope in Chile have conducted the deepest spectroscopic survey ever. They focused on the Hubble Ultra Deep Field, measuring distances and properties of 1600 very faint galaxies including 72 galaxies that have never been detected before. This wealth of new information is giving astronomers insight into star formation in the early Universe. www.sciencedaily.com/releas...

injectable gel helps heart muscle regenerate after heart attack
Researchers have used mouse models to demonstrate a new approach to restart cardiomyocyte replication after a heart attack: an injectable gel that slowly releases short gene sequences known as microRNAs into the heart muscle. www.sciencedaily.com/releas...

Key component for quantum computing invented
In a critical step towards scaling up quantum computers, physicists have invented a microcircuit based on topological insulators, a new phase of matter awarded the 2016 Nobel Prize in Physics. The circuit will be a vital component in the scaling up of quantum information systems. www.sciencedaily.com/releas...

In first, 3-D printed objects connect to WiFi without electronics
Engineers have developed the first 3-D printed plastic objects that can connect to other devices via WiFi without using any electronics, including a laundry bottle that can detect when soap is running low and automatically order more. www.sciencedaily.com/releas...
