New platform integrates THz photonics with planarized low-loss polymers

Integrated photonics extensively uses on-chip optical elements such as sources, splitters, modulators, and high-confinement waveguides embedded in a planar platform to efficiently process and route optical signals. There is a growing interest in integrated Mid-IR and THz photonics for telecommunications and sensing. In the THz frequency range, a prominent candidate for source integration is the THz quantum cascade laser.

Earth news

	Bering Land Bridge formed surprisingly late during last ice age, study finds A new study that reconstructs the history of sea level at the Bering Strait shows that the Bering Land Bridge connecting Asia to North America did not emerge until around 35,700 years ago, less than 10,000 years before the height of the last ice age (known as the Last Glacial Maximum).
	Far-flung forces caused the 2021 Pacific Northwest heat wave, say researchers An extreme heat wave struck the Pacific Northwest in June 2021. Temperatures soared above 40°C (104°F) across Oregon, Washington, and British Columbia, sometimes even approaching 50°C (122°F). Experts estimate that at least several hundred people died as a result.
	Deep learning can predict tsunami impacts in less than a second Detailed predictions about how an approaching tsunami will impact the northeastern coastline in Japan can be made in fractions of a second rather than half an hour or so—buying precious time for people to take appropriate action. This potentially life-saving technology exploits the power of machine learning.
	Real-time rip current identification tool uses AI and deep learning Beachgoers could be safer thanks to a new technology with the potential to give real-time updates of rip currents.
	Depletion of groundwater is accelerating in California's Central Valley, study finds Scientists have discovered that the pace of groundwater depletion in California's Central Valley has accelerated dramatically during the drought as heavy agricultural pumping has drawn down aquifer levels to new lows and now threatens to devastate the underground water reserves.
	'Epic' winter storm wallops US, leaving 1 mn without power More than a million US power customers were in the dark Friday as a "bomb cyclone" winter storm walloped the country, closing highways, grounding flights and causing misery for Christmas travelers.
	Deadly winter blizzard leaves US in pre-Christmas deep freeze A fearsome winter storm that pummelled the United States with blinding snow and powerful Arctic winds left over half a million customers without power Saturday as thousands of cancelled flights stranded travelers making last-minute dashes for Christmas.
	Savage US blizzard leaves 32 dead, power outages, travel snarls A brutal winter storm that brought Christmas chaos to millions of Americans will be slow to dissipate, the US National Weather Service said Monday, after intense snow and frigid cold caused power outages, travel delays and at least 32 deaths across the eastern part of the country.
	'Blizzard of the century' leaves nearly 50 dead across US Temperatures were expected to moderate across the eastern and midwest United States on Tuesday, after days of freezing weather from "the blizzard of the century" left at least 49 dead and caused Christmas travel chaos.
	Model analysis of atmospheric observations reveals methane leakage in North China Natural gas is a relatively clean burning fossil fuel, that causes less air pollution than coal and is widely used in the world. Recent studies have shown that the natural gas leaks from production, supply chain, and end-use facilities are a large source of atmospheric methane (CH4), and the leaking budget is underestimated in many places by bottom-up inventories.
	Homes that survived Boulder County fire hid another disaster inside: Research details this urban wildfire health risk On Dec. 30, 2021, one of the most destructive wildfires on record in Colorado swept through neighborhoods just a few miles from our offices at the University of Colorado Boulder. The flames destroyed over 1,000 buildings, yet when we drove through the affected neighborhoods, some houses were still completely intact right next to homes where nothing was left to burn.
	22 dead as savage US blizzard cuts power, snarls travel More than 200,000 Americans woke up without power on Christmas morning as a days-long winter megastorm that hammered several eastern US states Sunday left more than 20 people dead.
	Philippines floods force tens of thousands to flee homes Christmas Day floods in the Philippines forced the evacuation of nearly 46,000 people from their homes, civil defence officials said Monday.
	2022 was a historic year for climate change policies. What's next for 2023? 2022 was a landmark year for climate change action—and repercussions.
	Viewpoint: 3 reasons local climate activism is more powerful than people realize Global warming has increased the number of extreme weather events around the world by 400% since the 1980s. Countries know how to stop the damage from worsening: stop burning fossil fuels and shift to renewable energy, electrify transportation and industry, and reduce the carbon intensity of agriculture.
	Pressure mounts on Biden administration for decision on giant Willow oil field project in Alaska A major oil prospect on federal land in Alaska is hanging in the balance as pressure mounts on the Biden administration for a final decision to approve, or reject, the project.
	Another above-average wildfire season for 2022. How climate change is making fires harder to predict and fight. Harlene Schwander didn't need a second warning from firefighters as a blaze burned toward her home in Klamath River, California, in July.

Astronomy and Space news

	Is the Milky Way normal? Studying the large-scale structure of our galaxy isn't easy. We don't have a clear view of the Milky Way's shape and features like we do of other galaxies, largely because we live within it. But we do have some advantages. From within, we're able to carry out close-up surveys of the Milky Way's stellar population and its chemical compositions. That gives researchers the tools they need to compare our own galaxy to the many millions of others in the universe.
	Is mining in space socially acceptable? Traditional mining has been subject to a negative stigma for some time. People, especially in developed countries, have a relatively negative view of this necessary economic activity. Primarily that is due to its environmental impacts—greenhouse gas emissions and habitat destruction are some of the effects that give the industry its negative image.
	NASA makes asteroid defense a priority, moving its NEO surveyor mission into the development phase There's an old adage in the engineering field—what gets funded gets built. So it's sure to be a happy time over at the Planetary Society, as NEO Surveyor, the project the organization has primarily supported over the past few years, has made it through NASA's grueling budgetary process to reach the "development" stage, with an eye for a launch of the system in 2028.

Chemistry news

	Highly sensitive infrared polarizer based on sulfur waste created Polarimetric images can provide information such as shading and surface morphologies by using polarizers that selectively reflect the transverse electric (TE) field and transmit the transverse magnetic (TM) field of unpolarized incident light. However, current IR polarizers are mainly based on expensive and brittle ceramics (such as semiconductors and chalcogenides) with nano-gratings usually fabricated by time- and cost-consuming interference lithography.
	Functional analyses of RNA-related enzymes using a next-generation DNA sequencer Genetic information encoded in genomic DNA is transcribed to mRNAs and then the codons on mRNA are decoded by transfer RNAs (tRNAs) during protein synthesis. tRNAs deliver amino acids to ribosomes and proteins are synthesized from the amino acids on the ribosomes according to the decoded genetic information. Therefore, tRNA plays a key role during the translation of genetic information.
	Time to strike antifreeze off your list of usable poisons? Ethylene glycol is the most common ingredient in automotive antifreeze. But for years, it was used in deadly poisonings.
	Enhancing the conversion efficiency of powdered photocatalysts that generate hydrogen from water under visible light In 2019, Shinshu University Special Contract Professor Domen Kazunari and colleagues developed the powdered oxysulfide photocatalyst Y2Ti2O5S2 that absorbs sunlight of wavelengths below 650 nm and splits water into hydrogen and oxygen.
	Revealing intermolecular hydrogen bond's important role in separation, purification of structurally similar compounds Coal tar, once considered waste, has become a huge treasure trove because hundreds of compounds can be isolated from it. Most of these compounds tend to be aromatic hydrocarbons, polycyclic aromatic hydrocarbons, and heterocyclic compounds.

Biology news

	Despite ban, small turtle online pet trade in the US found to be flourishing A team of researchers at the University of Rhode Island, working with a colleague at the University of Richmond, has found that despite laws banning the sale of hatchling turtles, there is a thriving online market for them in the U.S. In their paper published in the open-access journal PLOS One, the group describes their survey of online sites selling turtles and whether such sites were adhering to federal regulations.
	Brown algae removes carbon dioxide from the air and stores it in slime Brown algae take up large amounts of carbon dioxide from the air and release parts of the carbon contained therein back into the environment in mucous form. This mucus is hard to break down for other ocean inhabitants, thus the carbon is removed from the atmosphere for a long time, as researchers at the Max Planck Institute for Marine Microbiology in Bremen now show.
	A checkerboard pattern of inner ear cells enables us to hear A Japanese research group has become the first to reveal that the checkerboard-like arrangement of cells in the inner ear's organ of Corti is vital for hearing. The discovery gives new insight into how hearing works from the perspective of cell self-organization and will also enable various hearing loss disorders to be better understood.
	Unraveling the selective transport of sugar and a hormone that underlies male fertility in plants Researchers at Nagoya University, Japan, have discovered a mechanism for the selective transportation of sugar and hormones in plants. The results also clarify that sugar transportation is necessary for male fertility in plants, which means pollen production. The findings were published in Proceedings of the National Academy of Sciences.
	Eating viruses can power microorganism's growth and reproduction Over a single day, in the placid waters of a single pond, a million virus particles might enter a single-celled organism known for the minuscule hairs, or cilia, that propel it through those waters.
	Mystery Nevada fossil site could be ancient maternity ward Scientists have uncovered new clues about a curious fossil site in Nevada, a graveyard for dozens of giant marine reptiles. Instead of the site of a massive die-off as suspected, it might have been an ancient maternity ward where the creatures came to give birth.

	Fly away home: rare Eastern Sarus cranes released in Thailand As the sun came up, 13 Thai Eastern Sarus cranes were released over a rippling reservoir in northeast Thailand, the latest effort to revive the almost-extinct species in the kingdom.
	Ethereal color variant of mysterious plant is actually new species Green leaves and photosynthesis were once considered essential characteristics of plants. However, some plants have stopped performing photosynthesis and take the nutrients they need from other organisms instead. One such mycoheterotrophic plant is the ghostly-looking Monotropastrum humile, which is widely found across East and Southeast Asia. It often grows in woodlands where there is little sunlight, obtaining the nutrients it needs by feeding off the hyphae of fungi.
	Study reveals inconsistent effect of ramet connection in homogeneous environments Physiological or clonal integration is a key ecological benefit where stolon or rhizome connections between ramets allow for translocation of resources from source-sites to sink-sites (in patchy or heterogeneous environments) within the clone. However, negative effects of ramet connection have also been found in previous studies.
	Researchers build cell atlas using scattered single-cell datasets Imagine a virtual human body, rich in complexity and detail, that enables scientists to simulate experiments that can't be conducted in vivo or in vitro. A team of Chinese researchers brought this vision closer to reality by developing a framework for seamless cell-centric data assembly and built the human Ensemble Cell Atlas (hECA) using data collected from scattered public datasets.
	Producers getting better at making alcohol-free beer and wine: Here's how it's done Drinking alcohol has been part of Australian culture for at least 240 years, and perhaps millennia prior.
