Absorbers suppress reflection and scattering of an incident wave by dissipating its energy into heat. As material absorption goes to zero, the energy impinging on an object is necessarily transmitted or scattered away. Specific forms of temporal modulation of the impinging signal can suppress wave scattering and transmission in the transient regime, mimicking the response of a perfect absorber wi
Topological surface states (TSSs) in a topological insulator are expected to be able to produce a spin-orbit torque that can switch a neighboring ferromagnet. This effect may be absent if the ferromagnet is conductive because it can completely suppress the TSSs, but it should be present if the ferromagnet is insulating. This study reports TSS-induced switching in a bilayer consisting of a topolog

This is a difficult task for which previous appro
In engineering, the "softness" of an object, as measured by an indenter, manifests as two measurable parameters: (i) indentation depth and (ii) contact area. For humans, softness is not well defined, although it is believed that perception depends on the same two parameters. Decoupling their relative contributions, however, has not been straightforward because most bulk—"off-the-shelf"—materials

An international team of scientists, studying evidence preserved in speleothems in a coastal cave, illustrate that more than three million years ago—a time in which the Earth was two to three degrees Celsius warmer than the pre-industrial era—sea level was as much as 16 meters higher than the present day. Their findings represent significant implications for understanding and predicting the pace o
American Journal of Roentgenology researchers have validated a first-of-its-kind machine learning-based model to evaluate immunohistochemical characteristics in patients with suspected thyroid nodules, achieving 'excellent performance' for individualized noninvasive prediction of the presence of cytokeratin 19, galectin 3, and thyroperoxidase based upon CT images.
Wildfires are getting worse — simply rebuilding after a disaster is no longer going to work in many communities. The reality of a warming West means we are better off rethinking our relationship with fire at a fundamental level.Transformative resilience — realigning our goals to accommodate future fire — is often the most rational option given the inevitability of fire in landscapes. Transforma
Same sex attraction isn't genetic. It's human The argument that some behaviour is "in our genes" is distrusted by the left. Too often it is used to whitewash terrible injustices. Yet it cannot be entirely dismissed. Certain patterns of behaviour and thought, such as the faculty of language acquisition, are very clearly a part of our genetic inheritance as a species. The instinct for justice itself
Bricked Servers On Thursday, porn production company Bang Bros purchased a website called PornWikiLeaks—and promptly shut it down permanently, scrubbing the website clean and literally incinerating the hard drives that stored its data. Why? As Motherboard reports , PornWikiLeaks was responsible for doxing over 15,000 adult film entertainers, and people frequently used the personal information pub
NASA astronaut Anne McClain was accused by her ex-wife for identity theft. The alleged crime was committed on the International Space Station from a NASA computer. Current legal channels exist to solve this dispute, but more heinous or international space crimes are going to be harder to reconcile. It looks like the long arm of the law stretches as far as space. Astronaut Anne McClain, 40, has be

In Hong Kong, umbrellas are commonly used for sun protection (and a symbol of protest). (AP Photo/Kin Cheung/) Many of us apply sunscreen when we go to the beach. But walking outside under the fierce summer sun—even if it's to run a quick errand—can be taxing: We sweat, we get exhausted, we burn and we expose ourselves to dangerous UV rays. In Asian countries, many people have a convenient tool a
Scooternado The city of Miami officially called for shared electric scooters to be removed from the streets on Thursday. And pronto — all scooters need to disappear by noon, Friday. That's because Category 3 hurricane Dorian, referred to as "a monster storm" by CNN, is destined to make landfall any time now. For the uninitiated, Category 3 hurricanes are, in a word, massive. All of Florida was pu
"I am obsessed with audiences," writes Phoebe Waller-Bridge in the introduction to the playtext of Fleabag . "How do you make an audience laugh in one moment, then feel something completely and profoundly different in the next?" The actor and writer has had six years to find out. Fleabag began as her one-woman play at the 2013 Edinburgh festival , before spawning two seasons of a BBC television s
Drone Fishing An Australian man uploaded video of himself fishing, from a chair, suspended over a lake, by a drone — and the whole stunt (somehow) appears to have gone surprisingly well. According to a story from RT , Kyneton, Victoria, fisherman Sam Foreman and his friends spent AUS$20,000 (US$13,460) building the drone, which features 12 motors, 25 batteries, and six 27-inch propellers. They th
