Where lions operate, grazers congregate ... provided food is great
Meals are typically family affairs for zebras, gazelles, cape buffalo and other grazing species in the African Serengeti, but in one of the first studies of its kind, ecologists have found grazing species can be more willing to share meals in areas frequented by lions.

Why young and female patients don't respond as well to cancer immunotherapy
UC San Diego researchers discovered that tumor cells in younger and female patients accumulate cancer-causing mutations that are more poorly presented to the immune system, better enabling tumors to escape detection and clearance.

Study reveals how two sex chromosomes communicate during female embryo development
Researchers at Massachusetts General Hospital (MGH) have solved a mystery that has long puzzled scientists: How do the bodies of female humans and all other mammals decide which of the two X chromosomes it carries in each cell should be active and which one should be silent?

Machine learning reveals role of culture in shaping meanings of words
What do we mean by the word beautiful? It depends not only on whom you ask, but in what language you ask them. According to a machine learning analysis of dozens of languages conducted at Princeton University, the meaning of words does not necessarily refer to an intrinsic, essential constant. Instead, it is significantly shaped by culture, history and geography.

Equatorial winds ripple down to Antarctica
A CIRES-led team has uncovered a critical connection between winds at Earth's equator and atmospheric waves 6,000 miles away at the South Pole. The team has found, for the first time, evidence of a Quasi-Biennial Oscillation (QBO) -- an atmospheric circulation pattern that originates at the equator--at McMurdo, Antarctica.

New superlattice material for future energy efficient devices
A team of international physicists including Jennifer Cano, PhD, of Stony Brook University, has created a new material layered by two structures, forming a superlattice, that at a high temperature is a super-efficient insulator conducting current without dissipation and lost energy. The finding is detailed in a paper published in Nature Physics.

Flies and mosquitoes beware, here comes the slingshot spider
Running into an unseen spiderweb in the woods can be scary enough, but what if you had to worry about a spiderweb - and the spider - being catapulted at you? That's what happens to insects in the Amazon rain forests of Peru, where a tiny slingshot spider launches a web - and itself - to catch unsuspecting flies and mosquitoes.

Widespread electric vehicle adoption would save billions of dollars, thousands of lives
A new study found that if EVs replaced 25% of combustion-engine cars currently on the road, the United States would save approximately $17 billion annually by avoiding damages from climate change and air pollution. In more aggressive scenarios -- replacing 75% of cars with EVs and increasing renewable energy generation -- savings could reach as much as $70 billion annually.

Swimming microparticles may help improve coolant performance
Your computer, car battery, or cell phone may one day be cooled down by swimming nanoparticles. Jeff Moran, an assistant professor of mechanical engineering at George Mason University's Volgenau School of Engineering, is investigating an innovative technology that could help remove waste heat from devices. Moran received an EAGER (Early-concept Grants for Exploratory Research) Award from the National Science Foundation for the project, "Feasibility of Self-Propelled Nanoparticles for Heat Transfer Enhancement."

2D materials for ultrascaled field-effect transistors
Since the discovery of graphene, two-dimensional materials have been the focus of materials research. Among other things, they could be used to build tiny, high-performance transistors. Researchers at ETH Zurich and EPF Lausanne have now simulated and evaluated one hundred possible materials for this purpose and discovered 13 promising candidates.

Research helps explain source of pathogen that causes bitter rot disease
Fungal spores responsible for bitter rot disease, a common and devastating infection in fruit, do not encounter their host plants by chance. Turns out, they have a symbiotic association with the plant, often living inside its leaves. The new way of looking at the fungal pathogen, Colletotrichum fioriniae, as a leaf endophyte -- bacterial or fungal microorganisms that colonize healthy plant tissue -- was the outcome of a two-year study conducted by researchers in Penn State's College of Agricultural Sciences.

Linking sight and movement
Harvard researchers found that image-processing circuits in the primary visual cortex not only are more active when animals move freely, but that they receive signals from a movement-controlling region of the brain that is independent from the region that processes what the animal is looking at.

Reconstructing global climate through Earth's history
Accurate temperature estimates of ancient oceans are vital because they are the best tool for reconstructing global climate conditions in the past. While climate models provide scenarios of what the world could look like in the future, paleoclimate studies (study of past climates) provide insight into what the world did look like in the past.

UMD researchers identify structure of blue whirls
'Blue whirls' -- small, spinning blue flames that produce almost no soot when they burn -- have attracted great interest since their discovery in 2016, in part because they represent a potential new avenue for low-emission combustion. Now, a team of researchers has identified how these intriguing whirls are structured.
