Going platinum: A non-toxic catalyst for clean, re-usable water
Platinum has set a new "gold standard" in jewelry, and now it's about to upscale the quality of your water.
Scientists reveal function of cell death enzyme capsase-7
Researchers have unmasked a component of the cell death process that could play a vital role in a better infection-fighting strategy.
Giving metal to microbes could reduce greenhouse gas
Like you and me, microbes need some metals in their diet to stay healthy. The metals help the microbes fully "digest" food. After a good meal, the microbes that gain energy by chemically reducing nitrate release a harmless byproduct: nitrogen, the gas that makes up 78% of Earth's atmosphere.
Deadly heatwaves threaten economies too
More frequent and intense heatwaves are the most deadly form of extreme weather made worse by global warming, with death tolls sometimes in the thousands, but they can also have devastating economic impacts too, experts say.

After Yellowstone, floodwaters near Montana's largest city
Floodwaters that rushed through Yellowstone National Park and surrounding communities earlier this week moved through Montana's largest city on Wednesday, flooding farms and ranches and forcing the shutdown of its water treatment plant.
Study of young adolescents suggests that intelligence is malleable
One in five students in the United States will not earn a high school diploma—and young adolescents who fall behind in school risk never catching up, leading to unemployment, poor health and poverty, research has shown.
The signals that make cells self-destruct
Most human hearts look nearly identical—muscle cells in the same places, blood vessel structures in the same orientations. Organs such as hearts or stomachs look alike and function the same across individual organisms in a species because cells follow rigorous processes during development that get them precisely where they need to go.
Researchers model accelerator magnets' history using machine learning approach
After a long day of work, you might feel tired or exhilarated. Either way, you are affected by what happened to you in the past.
Diffuse optics for medical diagnostics: Progress toward standardization
Among the various optics-based tools used in diagnostics, diffuse optics (DO) is rapidly emerging as one of the most attractive technologies. The technique is based on analyzing how light is absorbed and scattered by biological tissues, which relates to the tissue chemical composition and structure. One of the key advantages of DO is that it is non-invasive (it uses low-power near-infrared light)....
