Turning diamond into metal

Researchers have discovered a way to tweak tiny needles of diamond in a controlled way to transform their electronic properties, dialing them from insulating, through semiconducting, all the way to highly conductive, or metallic. This can be induced dynamically and reversed at will, with no degradation of the diamond material.

Trans-Neptunian object Arrokoth: Flattening of a snowman

The trans-Neptunian object Arrokoth, also known as Ultima Thule, which NASA's space probe New Horizons passed on New Year's Day 2019, may have changed its shape significantly in the first 100 million years since its formation. Researchers now suggest that the current shape of Arrokoth could be of evolutionary origin due to volatile outgassing.

How malaria parasites withstand a fever's heat

The parasites that cause 200 million cases of malaria each year can withstand feverish temperatures that make their human hosts miserable. Now, a team is beginning to understand how they do it. The researchers have identified a lipid-protein combo that springs into action to gird the parasite's innards against heat shock. Understanding how malaria protects its cells against heat and other...

Advancing multiprincipal alloys

The most significant advances in human civilization are marked by the progression of the materials that humans use. The Stone Age gave way to the Bronze Age, which in turn gave way to the Iron Age. New materials disrupt the technologies of the time, improving life and the human condition.

Safe resumption of research is important, feasible

At the onset of the COVID-19 pandemic, just as public institutions and businesses closed, research programs performing human participant research (HPR) also largely ceased operations. Now, universities and healthcare organizations conducting HPR are considering reopening.

Dog brains do not prefer faces

Even though dogs gaze into man's eyes, dog brains may not process faces as human brains do. A new study suggests that the canine visual system is organized differently: the face network found in primates may not extend to all mammals.

Scientist maps CO2 emissions for entire US to improve environmental policymaking

With wildfires in the West and hurricanes in the Gulf, the nation is affected by extreme weather-related events resulting from climate change. In response, lawmakers across the country are developing policies to reduce emissions, but the data they have is often inadequate. Scientists have now detailed greenhouse gas emissions across the entire US with details on economic sector, fuel and...

Risk factors for acute kidney injury after brain hemorrhage

Patients who suffer an intracerebral hemorrhage (ICH) face an increased risk of acute kidney injury (AKI) during their hospitalization. AKI can lead to sudden kidney failure, kidney damage or even death. Researchers have determined which ICH patients are at the highest risk for this kidney injury so doctors can take precautions to prevent it.
