High-performance golf clubs and airplane wings are made out of titanium, which is as strong as steel but about twice as light. These properties depend on the way a metal's atoms are stacked, but random defects that arise in the manufacturing process mean that these materials are only a fraction as strong as they could theoretically be. An architect, working on the scale of individual atoms, could

Human skin color reflects an evolutionary balancing act tens of thousands of years in the making. There's a convincing explanation for why human skin tone varies as a global gradient, with the darkest populations around the equator and the lightest ones near the poles. Put simply, dark complexion is advantageous in sunnier places, whereas fair skin fairs better in regions with less sun. That may s

Researchers are urging universities across the United States to find a new way to identify the next generation of scientists. A new study discovered that traditional admissions metrics for physics Ph.D. programs such as the Graduate Record Examination (GRE) do not predict completion and hurt the growth of diversity in physics, which is already the least diverse of the sciences.
On Monday, Senator Lindsey Graham, the South Carolina Republican, reiterated a position that cuts against the core of the Constitution. President Donald Trump "must" invoke emergency powers to construct a border wall, he wrote, "if the White House and Congress fail to reach a deal." The comment allies Graham with some immigration hard-liners in the Republican Party and is perhaps intended to aver
Computer systems produce a lot of heat. Data centers are full of buzzing cooling fans, and even smartphones can heat up with high use. Reducing energy consumption is one of the main challenges in information technology. But there is a theoretical, temperature-dependent lower limit to cooling, as stated by Rolf Landauer in the 1960s. Jan Klaers of UT now shows that by cleverly timing the interactio

Many real-world systems are interesting precisely because they can self-organize to form composite structures with novel "emergent" properties—colloquially, "more is different" (1). This is certainly true for living organisms where cells self-organize to form tissues, which make up organs, and so on. It is also true in geological and geophysical…
Last year, humans emitted approximately 37 billion tonnes of carbon dioxide into the atmosphere – a disastrous and unsustainable figure. To avoid the worst effects of climate change we could capture some of that carbon as it is released by power plants and store it permanently below ground. Better still, some of that waste carbon dioxide could be converted into useful chemicals or fuel.
Cardiff University researchers have uncovered new information about the underlying mechanisms for gastric cancer, providing hope of potential new therapies in the future.
