Extraordinary tensile strength and ductility of scalable nanoporous graphene

While the compressive strength-density scaling relationship of ultralight cellular graphene materials has been extensively investigated, high tensile strength and ductility have not been realized in the theoretically strongest carbon materials because of high flaw sensitivity under tension and weak van der Waals interplanar bonding between graphene sheets. In this study, we report that large-scal

High-tide flooding disrupts local economic activity

Evaluation of observed sea level rise impacts to date has emphasized sea level extremes, such as those from tropical cyclones.

STEM faculty who believe ability is fixed have larger racial achievement gaps and inspire less student motivation in their classes

An important goal of the scientific community is broadening the achievement and participation of racial minorities in STEM fields.

Theoretical guidelines to create and tune electric skyrmion bubbles

Researchers have long wondered whether ferroelectrics may present topological textures akin to magnetic skyrmions and chiral bubbles, the results being modest thus far.

Power flow-conformal metamirrors for engineering wave reflections

Recently, the complexity behind manipulations of reflected fields by metasurfaces has been addressed, showing that, even in the simplest scenarios, nonlocal response and excitation of auxiliary evanescent fields are required for perfect field control.

Lithiophilicity chemistry of heteroatom-doped carbon to guide uniform lithium nucleation in lithium metal anodes

The uncontrollable growth of lithium (Li) dendrites seriously impedes practical applications of Li metal batteries.

However, the lithiophilic nature of these carbon hosts is poorly understood. Herein, the lithiophilicity chemistry of hetero

Charge extraction via graded doping of hole transport layers gives highly luminescent and stable metal halide perovskite devices

Dog burial as common ritual in Neolithic populations of north-eastern Iberian Peninsula

Coinciding with the Pit Grave culture (4200-3600 years before our era), coming from Southern Europe, the Neolithic communities of the north-eastern Iberian Peninsula started a ceremonial activity related to the sacrifice and burial of dogs. The high amount of cases that are recorded in Catalonia suggests it was a general practice and it proves the tight relationship between humans and these animal

Researchers Create 'Rat Cyborgs' That People Control With Their Minds

I’ll just come right out and say it: Scientists have created human-controlled rat cyborgs. Lest you think this is some media sensationalism at work, here’s the actual title of the paper under discussion, which came out last week in Scientific Reports: “Human Mind Control of Rat Cyborg’s Continuous Locomotion with Wireless Brain-to-Brain Interface.” That pretty much says it all.

Multitasking increases in online courses compared to face-to-face

The phenomenon of multitasking across three or four internet-connected devices simultaneously is increasingly common. Researchers were curious to know how often this happens during online education, a method of delivering college and even high school courses entirely via an internet-connected computer as opposed to a traditional face-to-face course with a teacher physically present.

Massive Bolivian earthquake reveals mountains 660 kilometers below our feet

Geophysicists used data from an enormous earthquake in Bolivia to find mountains at the base of the mantle's transition zone, located 660 kilometers below our feet. Their statistical model didn't allow for precise height measurements, but these mountains may be bigger than anything on the surface of the Earth. The researchers also examined the top of the transition zone (410 km down) and did not f
