<p class="p1"><span class="s1">Carbon-fiber composites – stronger than steel and lighter than aluminum – can easily and cost-effectively be recycled into new material just as robust as the originals, a team of researchers led by the ��ɫ��Ƶ has found.</span></p>

<p>Strange as it may seem, a bird bigger than Big Bird once lived above the Arctic Circle. The flightless bird, known as <em>Gastornis</em>, roamed Ellesmere Island next to Greenland about 50 million years ago, even during the twilight months of winter. </p>

<p>The first direct evidence that humans played a substantial role in the extinction of the huge, wondrous beasts inhabiting Australia some 50,000 years ago -- in this case a 500-pound bird -- has been discovered by a ��ɫ��Ƶ-led team.</p>

<p>The United States could slash greenhouse gas emissions from power production by up to 78 percent below 1990 levels within 15 years while meeting increased demand, according to a new study by NOAA and ��ɫ��Ƶ researchers.</p>

<p>In the ever-escalating evolutionary battle with drug-resistant bacteria, humans may soon have a leg up thanks to adaptive, light-activated nanotherapy developed by researchers at the ��ɫ��Ƶ.</p>
<p>Antibiotic-resistant bacteria such as Salmonella, E. Coli and Staphylococcus infect some 2 million people and kill at least 23,000 people in the United States each year. Efforts to thwart these so-called “superbugs” have consistently fallen short due to the bacteria’s ability to rapidly adapt and develop immunity to common antibiotics such as penicillin.  </p>

<p>Pregnant and postpartum women at risk of depression are less likely to suffer depression when they meditate or get in a yoga pose than when they are treated with psychotherapy or antidepressants, a new study led by ��ɫ��Ƶ researchers has found.</p>

<p>New research led by the ��ɫ��Ƶ indicates an ongoing loss of ice on Niwot Ridge and the adjacent Green Lakes Valley in the high mountains west of Boulder is likely to progress as the climate continues to warm.</p>

<p>An unusually star-deprived black hole at the site of two merged galaxies could provide new insight into black hole evolution and behavior.</p>

<p>The human gut harbors a teeming menagerie of over 100 trillion microorganisms and exercising early in life can alter that microbial community for the better, promoting healthier brain and metabolic activity over the course of a lifetime.</p>

<p>Water managers in Colorado and the West scrambling to meet the growing demand for increasingly scarce water supplies caused by large populations far from water resources, climate change and drought need to focus more effort on conserving water, including addressing reservoir evaporation, say ��ɫ��Ƶ researchers.</p>
