Composite metal foam outperforms aluminum for use in aircraft wings

The leading edges of aircraft wings have to meet a very demanding set of characteristics. New research shows that a combination of steel composite metal foam and epoxy resin has more desirable characteristics for use as a leading-edge material than the aluminum currently in widespread use.

Exploring the effect of fasting on age-related diseases

There are many indications that fasting promotes longevity. In recent years, much attention has been devoted to so-called caloric restriction mimetics (CMRs), substances that simulate the health-promoting effects of fasting without the need of life-style change. A study reports the identification of a novel candidate CRM. The substance may prove useful in the further research for the treatment of age-related diseases.

The night gardeners: Immune cells rewire, repair brain while we sleep

Science tells us that a lot of good things happen in our brains while we sleep — learning and memories are consolidated and waste is removed, among other things. New research shows for the first time that important immune cells called microglia — which play an important role in reorganizing the connections between nerve cells, fighting infections, and repairing damage — are also primarily active while we sleep.

Your healthcare provider's expectations on whether a treatment works may impact its effectiveness

If a doctor expects a treatment to be successful, a patient may experience less pain and have better outcomes, according to a new study. The findings reveal how social interactions between hypothetical healthcare providers and patients have the power to influence how patients perceive the effectiveness of a treatment, even when it is a placebo.
