Soliton microcomb range measurement

Laser-based range measurement systems are important in many application areas, including autonomous vehicles, robotics, manufacturing, formation flying of satellites, and basic science. Coherent laser ranging systems using dual-frequency combs provide an unprecedented combination of long range, high precision, and fast update rate. We report dual-comb distance measurement using chip-based soliton microcombs. A single pump laser was used to generate dual-frequency combs within a single microreson...

Ultrafast optical ranging using microresonator soliton frequency combs

Light detection and ranging is widely used in science and industry. Over the past decade, optical frequency combs were shown to offer advantages in optical ranging, enabling fast distance acquisition with high accuracy. Driven by emerging high-volume applications such as industrial sensing, drone navigation, or autonomous driving, there is now a growing demand for compact ranging systems. Here, we show that soliton Kerr comb generation in integrated silicon nitride microresonators provides a rou...

Infrared hyperbolic metasurface based on nanostructured van der Waals materials

Metasurfaces with strongly anisotropic optical properties can support deep subwavelength-scale confined electromagnetic waves (polaritons), which promise opportunities for controlling light in photonic and optoelectronic applications. We developed a mid-infrared hyperbolic metasurface by nanostructuring a thin layer of hexagonal boron nitride that supports deep subwavelength-scale phonon polaritons that propagate with in-plane hyperbolic dispersion. By applying an infrared nanoimaging technique,...

U-Th dating of carbonate crusts reveals Neandertal origin of Iberian cave art

The extent and nature of symbolic behavior among Neandertals are obscure. Although evidence for Neandertal body ornamentation has been proposed, all cave painting has been attributed to modern humans. Here we present dating results for three sites in Spain that show that cave art emerged in Iberia substantially earlier than previously thought. Uranium-thorium (U-Th) dates on carbonate crusts overlying paintings provide minimum ages for a red linear motif in La Pasiega (Cantabria), a hand stencil...

Single-cell bioluminescence imaging of deep tissue in freely moving animals

Bioluminescence is a natural light source based on luciferase catalysis of its substrate luciferin. We performed directed evolution on firefly luciferase using a red-shifted and highly deliverable luciferin analog to establish AkaBLI, an all-engineered bioluminescence in vivo imaging system. AkaBLI produced emissions in vivo that were brighter by a factor of 100 to 1000 than conventional systems, allowing noninvasive visualization of single cells deep inside freely moving animals. Single tumorig...

Too Much TV Could Boost Your Odds for a Blood Clot
The study found that people who spend too much time in front of the TV are at increased risk for blood clots in their veins -- a condition called venous thromboembolism (VTE).

Exercising Yourself to Death: The Risk of Rhabdo
Rhabdomyolysis is a syndrome involving muscle breakdown and damage. When muscles are injured, they release their contents, including a muscle enzyme, into the bloodstream. The disorder is dangerous but rare. In one study, 22 people out of 100,000 were known to have it.

Heavy Drinkers Put Themselves at Risk for Dementia
Overall, alcohol abuse was associated with a three times greater risk for all types of dementia. Alcohol was a factor in 57 percent of the 57,000 cases of early onset dementia, which is dementia that develops before age 65.
