Each year, pregnant female elephant seals take an approximately 240-day trek over 10,000 kilometers across the Eastern North Pacific Ocean before returning to their breeding beaches to give birth within five days of their arrival. Now, a study appearing February 28 in the journal biology Current Biology finds that this impressive navigation ability depends on an internal map sense, which functions much like a built-in GPS.

New research from scientists at Cummings School of Veterinary Medicine at Tufts University supports and builds on the researchers’ previous findings that opioid use in female rats before pregnancy—even if not used during pregnancy itself—could result in a higher likelihood that male offspring will develop type 2 diabetes and metabolic syndrome, conditions that increase the risk of heart disease and stroke.

Controlling the spin of a single unpaired electron is no easy task. In this research, scientists show that visible light can be used to influence a relative orientation of an unpaired electron in a molecule in a magnetic field. This process can potentially be applied across a class of small molecules and is an important step toward novel technologies such as quantum computers and quantum sensors.

A new study tracked lithium metal deposition and removal from a battery anode while it was cycling to find clues as to how failure occurs. The research could help improve the use of pure lithium metal in anodes for electric vehicle batteries, which would reduce battery weights and dramatically extend driving range.

The icefields that stretch for hundreds of miles atop the Andes mountain range in Chile and Argentina are melting at some of the fastest rates on the planet. The ground that was beneath this ice is also shifting and rising as these glaciers disappear. Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie Patagonia.

In humans, virtually every cell stores fat. However, patients with a rare condition called congenital lipodystrophy, which is often diagnosed in childhood, cannot properly store fat, which accumulates in the body’s organs and increases the risk of early death from heart or liver disease. In 2001, a transmembrane protein called seipin was identified as a molecule essential for proper fat storage, although its mechanism has remained unknown.
