As expected, the entire iPhone 12 lineup is compatible with faster 5G networks, but Apple’s website confirms that support for high-frequency mmWave bands is limited to models sold in the United States. This includes compatibility with Verizon’s new 5G Ultra Wideband network, which as of today is available in 55 cities across the country.
mmWave is supported on all iPhone 12 models sold in the United States, ranging from the iPhone 12 mini to the iPhone 12 Pro Max. iPhone 12 models sold in all other countries and regions are limited to sub-6GHz bands for 5G.
mmWave is a set of 5G frequencies that promise ultra-fast speeds at short distances, making it best suited for dense urban areas. By comparison, sub-6GHz 5G is generally slower than mmWave, but the signals travel further, better serving suburban and rural areas. In most countries that offer 5G, sub-6GHz networks are more common.
Many of California’s 33 million acres of forests face widespread threats stemming from past management choices. Today the U.S. Forest Service estimates that of the 20 million acres it manages in California, 6-9 million acres need to be restored.
Forest restoration basically means removing the less fire-resistant smaller trees and returning to a forest with larger trees that are widely spaced. These stewardship projects require partnerships across the many interests who benefit from healthy forests, to help bring innovative financing to this huge challenge.
The California Wildfires in Photos
We are engineers who work on many natural resource challenges, including forest management. We’re encouraged to see California and other western states striving to use forest management to reduce the risk of high-severity wildfire.
But there are major bottlenecks. They include scarce resources and limited engagement between forest managers and many local, regional and state
For every two deaths attributed to COVID-19 in the U.S., a third American dies as a result of the pandemic, according to new data publishing Oct. 12 in the Journal of the American Medical Association.
The study, led by researchers at Virginia Commonwealth University, shows that deaths between March 1 and Aug. 1 increased 20% compared to previous years — maybe not surprising in a pandemic. But deaths attributed to COVID-19 only accounted for 67% of those deaths.
“Contrary to skeptics who claim that COVID-19 deaths are fake or that the numbers are much smaller than we hear on the news, our research and many other studies on the same subject show quite the opposite,” said lead author Steven Woolf, M.D., director emeritus of VCU’s Center on Society and Health.
The study also contains suggestive evidence that state policies on reopening early in April and May may have fueled the
It is assumed that the brain has homeostatic mechanisms to prevent the depletion of cellular energy, required for all cellular activities. For example, the blood flow increases, and oxygen and glucose are actively delivered in the brain region in which neural firing activity occurs. Besides, the cerebral blood flow and glucose uptake into the cells fluctuate accompanying the variations of cellular activities in the brain across the sleep-wake states of animals. Under these brain energy homeostatic mechanisms, it is assumed that the cellular energy status in the brain could be maintained constant in all physiological conditions including across the sleep-wake states of animals. However, this has not been experimentally proven.
To investigate whether the cellular energy status in the brain of living animals is always constant or variated, the researchers measured the neuronal intracellular concentration of adenosine 5′-triphosphate (ATP), the major cellular energy metabolite, using a fluorescent sensor in the
When a buddy of Russ Elliott‘s asked if he’d join him in starting a telecom company, he flat out said no. While his friend had been a great help building a website he needed, the venture didn’t have any financial backing and Elliott wasn’t versed in internet connectivity.
But when his friend took the unusual step of sending him a motivational postcard — something with an iceberg and a corny message about not knowing what’s out there unless you took a risk — it played on his mind. Elliott had an MBA. He had drive. He decided to embrace the inspirational cliché.
With that, some 20 years ago Elliott helped launch what became a successful business in Colorado called Brainstorm Internet, serving as its president for 13 years.
Female surgeons at a large academic medical center perform less complex surgical procedures than their male counterparts, according to a new study by researchers at Massachusetts General Hospital (MGH). This study, published in Annals of Surgery, is one of the first to measure the problem of underemployment among female surgeons in the United States, which can affect compensation, career advancement and job satisfaction.
Only about one in five surgeons practicing in U.S. is female. Unemployment is virtually nonexistent among surgeons, but many female surgeons, as well as professional women in other fields, experience underemployment — the underuse of skills — according to the Federal Reserve Bank. “Women in surgery talk among themselves about how they may be perceived as less confident or competent, and for those reasons they may have less opportunity to do exciting and challenging cases,” says Cassandra Kelleher, MD, a pediatric surgeon at MGH and senior
In a collaborative effort between scientists and personnel on military bases in 31 states in the continental U.S. and Puerto Rico, researchers surveyed for an infection caused by an emerging fungal pathogen that afflicts snakes. The effort found infected snakes on military bases in 19 states and Puerto Rico, demonstrating that the fungus is more widely distributed than was previously known. The team reports the findings in the journal PLOS ONE.
“Ophidiomycosis — formerly known as ‘snake fungal disease’ — is an emerging infectious disease caused by the fungus Ophidiomyces ophidiicola,” said Dr. Matt Allender, a professor in the veterinary diagnostic laboratory at the University of Illinois Urbana-Champaign who led the new study. “It has been documented in over 15 genera of wild and captive snakes. Infection with the pathogen causes a wide range of clinical signs in snakes, from difficulty shedding skin, to crusts and ulcers on the
NOAA/NASA’s Suomi NPP satellite captured another startling image of the August Complex of fires that has grown to over 1,000,000 acres burned (1,006,140 acres total) and because of that grim milestone the complex has been dubbed a “gigafire.” The August Complex is only 58% contained. Inciweb reports that: “In the northeast zone, active behavior continues. Structures in Hidden Valley, Trinity Pines/Post Mountain, Wildwood and Platina are threatened by fire spread. Short range spotting and fire spread toward Hidden Valley has increased potential for impact to structures.”
Another view that can be captured by Suomi NPP satellite is a false-color image. The false-color image is collected by the VIIRS (Visible Infrared Imaging Radiometer Suite) instrument suite using corrected reflectance bands. Burned areas or fire-affected areas are characterized by deposits of charcoal and ash, removal of vegetation and/or the alteration of vegetation structure. When bare soil becomes exposed, the brightness in Band
WASHINGTON (Reuters) – The U.S. Justice Department is expected to sue Alphabet’s Google <GOOGL.O> as soon as next week, and is currently urging state attorneys general to sign onto the lawsuit, according to three sources familiar with the process.
The lawsuit is expected to accuse Google, builder of the world’s dominant search engine, of looking to disadvantage rivals such as Microsoft’s Bing by depriving them of the data about users and user preferences that they need to improve and to advertise to people.
The Justice Department has also been investigating Google’s “search advertising,” the ads that appear under a search box if a person looks up a consumer item like “dishwasher.” Google controls the sale of the space under these searches, as well as the tools to make those ad sales.
Google has repeatedly denied any wrongdoing. The Justice Department declined to comment.
