President Joe Biden's pick to lead the Federal Aviation Administration announced Saturday evening that he would withdraw his nomination after it became clear he lacked the votes for Senate confirmation.

Denver International Airport CEO Phillip Washington was criticized by Senate Republicans since being nominated eight months ago on a number of issues, including his slim credentials in aviation safety and potential legal entanglements. Transportation Secretary Pete Buttigieg confirmed Washington's withdrawal in a tweet late Saturday in which he blamed his failed nomination on "partisan attacks and procedural obstruction."

REPUBLICANS BLAST BIDEN FAA CHIEF NOMINEE: 'SIMPLY NOT QUALIFIED FOR THE JOB'

A White House official said in a statement to CNN that the administration would work to find a new nominee to lead the FAA, which has been without a Senate-confirmed leader since March 2022, when then-FAA Administrator Steve Dickson stepped down less than halfway through his five-year term.

Though Biden nominated Washington last July, he did not get a committee hearing until earlier this month. Washington — who ran transit agencies in Denver, Colorado, and Los Angeles, California — has only served in his current role as chief executive of the Denver International Airport for less than two years. This role is his only aviation experience. The longtime transit executive is a close Biden ally and led the 46th president's transition team for the Transportation Department, which includes the FAA.

Republicans remained unified in opposition to Washington over his resume and concerns about his name appearing in search warrants related to a corruption probe in Los Angeles. Washington had denied any wrongdoing and said he was not contacted by law enforcement.

Support among others on the Senate Commerce, Science, and Transportation Committee began to wane in recent weeks, which came to a head when Sen. Maria Cantwell (D-WA), who chairs the panel, abruptly called off a vote on Washington's nomination scheduled for Wednesday. The move appeared to indicate that Washington lacked the votes to move his nomination out of committee.

Sen. Kyrsten Sinema (I-AZ), a Democrat-turned-Independent who still caucuses with her former party and sits on the panel, had indicated her opposition, a person familiar with the matter told the . She had not publicly said how she planned to vote on the nomination ahead of Wednesday's being postponed. Sen. Tammy Duckworth (D-IL) told Politico that the vote was delayed due to "one person," though she would not say who.

Sens. Jacky Rosen (D-NV) and Jon Tester (D-MT), a moderate who faces a tough 2024 reelection fight, had also declined to say how they would vote on the nomination as the vote approached.

Sen. Eric Schmitt (R-MO), a Republican on the committee, told the Washington Examiner in an interview Wednesday that Washington's nomination was in more peril than Democrats wanted to admit at the time.

The FAA has faced scrutiny in recent months amid air safety and overall competency concerns after massive spikes in delayed or canceled flights and near-misses on runways.

After two years of work in Egypt, archaeologists have discovered hundreds of tombs with interconnected tunnels and mummies, in addition to a pyramid identifying a previously unknown queen.

The discoveries, made at Saqqara in Giza, the archaeological site near Cairo, Egypt, are believed to be from the New Kingdom period, dating to 1550-1070 B.C.

Among the finds, archaeologists discovered “300 beautiful coffins” containing mummies in surprisingly good condition.

"Burials from the New Kingdom were not known to be common in the area before, so this is entirely unique to the site," Zahi Hawass, an archaeologist and Egyptologist who formerly served as Egypt's minister of antiquities, told Live Science. "The coffins have individual faces, each one unique, distinguishing between men and women, and are decorated with scenes from the Book of the Dead. Each coffin also has the name of the deceased."

"This shows that mummification reached its peak in the New Kingdom," Hawass added. "Some coffins have two lids, and the most amazing coffin so far has a mask of a woman made completely of solid gold."

The discoveries were made on Nov. 4, the 100-year anniversary of unearthing King Tut’s tomb.

Due to the close proximity to King Tut’s tomb, researchers think the mummies may belong to those of his closest advisers and generals during his reign from 1333 B.C. until 1323 B.C.

Hawass said the burials were found in 22 newly discovered interconnected tunnels, which range from 30 to 60 feet deep.

Additionally, the archaeologists found a pyramid identifying the Egyptian queen Neith.

"It is amazing to literally rewrite what we know of history, adding a new queen to our records,” Hawass said.

The discoveries follow a trove of ancient artifacts, including the uncovering of 2,500-year-old coffins, found in May.

A selection of the discoveries will be displayed at the Grand Egyptian Museum in Giza, which is set to open next year.

Researchers believe they could have identified the youngest planet at any time observed in the galaxy.

The planet, thought to be about 1.5 million many years previous and positioned 395 light-weight-yrs from Earth, is nonetheless staying formulated, with gas and dust bordering it, according to study released in the Astrophysical Journal Letters.

PERSEIDS METEOR SHOWER PEAK Anticipated TO BE MUTED THIS 7 days

"If confirmed, this CPD-web hosting world would be a person of the youngest exoplanets detected to date. Observing planets at this young age makes it possible for us to position powerful constraints on the system and timescale of planet development, very important to attaining new insights into the development and evolution of large planets," the researchers wrote in the analysis.

For comparison, Earth is believed to be about 4.54 billion yrs aged. The planet is located in the constellation Ophiuchus in close proximity to a young star named AS 209, which is also about 1.5 million a long time outdated, according to the research.

Experts utilized a system known as the Atacama Big Millimeter/submillimeter Array and the ALMA telescope to accumulate details about the earth. They concluded that the planet has been enveloped by product that customarily will make planets, these types of as gasoline and dust, frequently referred to as circumstellar disks.

“It is like seeking at our own previous,” Myriam Benisty, an astronomer who co-authored the analyze, stated, according to the New York Times.

The discovery of the circumplanetary disk has presented proof that many planets are usually cradled by the material that types them for prolonged intervals of time during their formation, according to the research. It is not clear how substantial the Earth's circumplanetary disk was throughout its early many years, Anders Johansen, an astronomer who did not take part in the examine, informed the outlet.

NASA has taken a journey down under.

The area company declared on Tuesday that it has partnered with the privately owned spaceport Equatorial Start Australia to launch three suborbital sounding rockets in June and July from the company's spaceport in the Outback. NASA will use these rockets to conduct astrophysics experiments from a distinct point of view.

"This industrial start variety in Australia opens up new access to the Southern Hemisphere's evening sky, growing the opportunities for long term science missions," said Thomas Zurbuchen, NASA associate administrator for the Science Mission Directorate, in a press release.

“We’re enthusiastic to be able to launch critical science missions from the Southern Hemisphere and see targets that we just can't from the United States,” mentioned Nicky Fox, director for NASA’s Heliophysics Division. “The launches this summer season will enable us to investigate how a star’s mild can influence a planet’s habitability, amongst other factors."

Two of the 3 rockets will precisely concentration on two planets orbiting Alpha Centauri, one particular of the closest stars to the solar. The third rocket will analyze X-rays emanating from the clouds of fuel and particles that lingers in the house between stars.

The 3 unmanned rockets will launch among June 26 and July 12 while carrying instruments for facts collection into the atmosphere. These launches will be the very first despatched up by ELA's Arnhem House Center, primarily based in Dhupuma Plateau near Nhulunbuy, on the lands of the Yolngu people today.

"We are excited and very pleased that our Arnhem House Centre will be the first spaceport in Australia to conduct a business house launch," said Michael Jones, ELA government chairman and group CEO.

Australian leaders had superior factors to say about the start. “This task will convey alongside one another global and community business to take Australia’s area sector into a new era,” reported Primary Minister Anthony Albanese, in accordance to the Sydney Morning Herald.

"We've been doing work tough considering the fact that 2015 to construct the ASC to make ELA the preeminent multiuser business place launch organization in the environment," Jones reported. "Acquiring NASA as our 1st purchaser will let us to verify the capabilities of ELA and the ASC as nicely as the gains of launching close to the equator. It will imply that about the following 5 several years, the ASC will ramp up to be capable of launching far more than 100 launches a calendar year."

NASA previous released rockets from Australia in 1995 when it despatched many rockets into orbit from the military services-operated Royal Australian Air Power Woomera Selection Intricate.

K-9s may be perfectly outfitted to detect COVID-19, in accordance to a new examine.

Pet dogs could be utilized to examination crowds for coronavirus via sweat samples, which could expedite the process of testing crowds for COVID-19 in instances of mass infection, according to a new study posted Wednesday in PLOS Just one. The canine have been found to be as productive as PCR exams in detecting the virus, scientists claimed.

The scientists, who hailed from French institutions, experienced a group of dogs to sniff samples of human sweat and sit down if they detected the virus. The methodology resembled that applied by police dogs to sniff out explosives or medications.

Scientists then took the canines to the Alfort School of Veterinary Medicine in France, in which they sniffed 335 sweat samples from human volunteers. The dogs' detection price was 97% correct in figuring out persons who experienced previously tested favourable for COVID-19 with a PCR exam and 100% accurate in detecting COVID-19 in individuals who had not seasoned signs and symptoms. The canine have been also noticeably more quickly at detecting the virus than antigen checks, the most frequent choice utilised at property.

The samples had been drawn from different areas of the human body, which includes the armpit, the back again of the neck, and worn facial area masks, the researchers noted.

Far more research will require to be accomplished to decide how pet dogs can sniff out the virus, scientists said.

The knowledge appear to correlate with related experiments in the earlier, but this experiment marked the initially recognised examine that compares the benefits to PCR and antigen assessments.

Illustration showing what exoplanet 55 Cancri e could seem like, based mostly on recent knowledge of the world. 55 Cancri e is a rocky planet with a diameter virtually twice that of Earth orbiting just .015 astronomical models from its Sun-like star. Mainly because of its tight orbit, the earth is exceptionally very hot, with dayside temperatures achieving 4,400 degrees Fahrenheit (about 2,400 degrees Celsius).

One not long ago investigated exoplanet seems to be the epitome of "hell on earth."

NASA declared options on Thursday to examine two exoplanets with the James Webb Area Telescope right after it finalizes its set up in the future couple weeks. One of these planets, regarded as "55 Cancri e," is regarded a "super-Earth" and seems to be a crimson-incredibly hot ball of lava and fireplace.

"Visualize if Earth ended up substantially, substantially nearer to the Sunlight," NASA claimed in a push statement. "So shut that an entire yr lasts only a couple of hours. So near that gravity has locked a person hemisphere in long lasting searing daylight and the other in countless darkness. So near that the oceans boil absent, rocks get started to soften, and the clouds rain lava."

55 Cancri e orbits much less than 1.5 million miles from its home star, or 1/25 the length amongst Mercury and the sunshine in our photo voltaic program.

A single of the many thoughts that NASA researchers wish to remedy features regardless of whether it is "tidally locked." Whilst most planets like 55 Cancri e do not usually rotate, the warmth signature of the exoplanet, or tremendous-Earth, appears to imply otherwise thanks to its shifting warmth condition.

"Observations of 55 Cancri e from NASA's Spitzer Room Telescope recommend that the most popular region is offset from the section that faces the star most instantly," NASA explained. "Although the complete amount of money of warmth detected from the day side does fluctuate."

A handful of theoretical explanations might provide insight, this kind of as the existence of a dynamic environment that forces the warmth to shift close to.

"55 Cancri e could have a thick ambiance dominated by oxygen or nitrogen," explained Renyu Hu of NASA's Jet Propulsion Laboratory in Southern California. This would contain the heat within the planet's environment and induce it to change all around depending on different planetary variables.

It is also probable that the earth is slowly rotating and so has a day-evening cycle.

"That could describe why the best aspect of the planet is shifted," stated Alexis Brandeker, a researcher from Stockholm College whose staff normally focuses on 55 Cancri e. "Just like on Earth, it would choose time for the floor to heat up. The hottest time of the working day would be in the afternoon, not ideal at noon."

The James Webb Place Telescope could help researchers recognize this remarkably heated planet. 55 Cancri e will be one particular of two planets to provide as the concentration for the initial 12 months of James Webb House Telescope's use. The other planet, regarded as "LHS 3844 b," is drastically cooler than 55 Cancri e and would offer you scientists an chance to analyze "strong rock on an exoplanet surface area." The telescope is currently being run as a result of various tests to verify the instrument's viability.

55 Cancri e was found in 2004 by researchers on the lookout for variants in a star's radial velocity. The earth is approximated to be 7.99 times as huge as Earth and is made up of notably large quantities of volcanic exercise.
