Lending a hand to protective immunity

Lending an iron hand to spintronics

As semiconductor electronics push up against the limits of Moore’s law, physicists are seeking new ways to manipulate and store information in matter. A promising new direction is “spintronics” [1], a kind of electronics built around the spin carried by electrons, rather than the charge. Spin is the basis of ferromagnets, which are magnets in which the electron spins are aligned. The informatio...

A physiologist in Africa: lending a hand in developing countries.

With the passing of the presidential campaign of 1988, the American public and the Bush administration have come to the realization that the country has major problems. The agenda for addressing these problems will be set during the first few months of 1989. Will the Bush administration or Congress set the agenda for the coming year? This question will be addressed as we watch the play of perso...

"Lending a hand" to patients with type 2 diabetes: a simple way to communicate treatment goals.

Because sugar was historically the defining feature of diabetes mellitus (meaning “excess urination of honey”), treatment focused primarily on lowering blood glucose levels until recently. However, based on high-quality evidence from meta-analyses, glucose control should no longer be the main focus of treatment. A new approach to the care of adults with type 2 diabetes emphasizes proven interve...

Evolution: Lending a Helping Hand in Sperm Competition?

Most females mate with many males. This can be costly, but the benefits to females are often unclear. A new study raises the possibility that females could benefit through an unconventional genetic pathway, while also showing that males can inadvertently increase rival males' fitness in surprising ways.
