Mysterious Drone Sightings; How Soundwaves Make Objects Levitate in Mid-Air; New Snowplow Driving Simulator Helps Get Roads Cleared Safer, More Efficiently.

COY WIRE, CNN 10 ANCHOR: Hello everyone, I`m Coy Wire, welcome to CNN 10, the best 10 minutes in news because of you. Happy Friday, it is Friday,

December 13th, and this is the last show of 2024. We`ve got winter break coming up, we hope you get lots of friends and family time over the

holidays, the most wonderful time of the year.

We start our final show of the year with some peculiar happenings in New Jersey, where weeks of unexplained drone sightings across the state have
 

peculiar [pɪˋkjuljɚ] adj. 奇怪的；乖癖的；罕见的

happening [ˋhæpənɪŋ] n. 事情，事件；即兴演出

prompted a joint federal and state investigation. The Federal Aviation Administration, or FAA, says the sighting started on November 18th near

Morris County, New Jersey. There isn`t a clear description of the airborne crafts, they often appear in clusters high in the sky when it`s dark, but
 

craft [kræft] n. 船；飞机；宇宙飞船

they`ve been reported to be about six feet in diameter, which is of course larger than the typical size of a drone that you might see someone flying

as a hobby.

So what are they? Who`s flying them? And where are they coming from? Nobody seems to know. Residents there are understandably freaked out, they`ve
 

freak out 暂时对自己失去控制, 发疯

frequently seen the drones hovering overhead and have noticed they seem to be hanging over critical sites like U.S. Military Research Facility or even

over President-elect Donald Trump`s golf course in Bedminster. This has escalated the security concerns of federal and state officials and even

prompted the FAA to issue temporary flight restrictions over the properties.

While New Jersey`s Governor Phil Murphy has said there is no known threat to the public, some state lawmakers briefed at the New Jersey State Police

headquarters this week are demanding more transparency into the investigation. CNN`s Josh Campbell has more on this mystery that`s baffling

baffle [ˋbæf!] v. 使困惑

folks all across the country.

(BEGIN VIDEOTAPE)

JOSH CAMPBELL, CNN CORRESPONDENT: All the ones over here, there`s two behind here.

UNIDENTIFIED FEMALE: I think the creepy part is not that it`s just a drone, that they`re so large.
 

creepy [ˋkripɪ] adj. 令人毛骨悚然的

CAMPBELL (voice-over): Growing frustration and demands for answers from New Jersey residents over a mystery in the skies.

UNIDENTIFIED MALE: Another drone.

CAMPBELL (voice-over): Weeks of mysterious nighttime drone sightings across the state, including near military sites and other critical

infrastructure, has left some residents unsettled.
 

unsettled [ʌnˋsɛt!d] adj. 焦虑不安的，心绪不宁的; nervous and worried; unable to relax

MARK TAYLOR, MAYOR FLORHAM PARK: They look like a small car to me. Their wingspans are probably six feet across.

CAMPBELL (on camera): Eyewitnesses say these spotted drones are much larger than those used by hobbyists. Law enforcement described one encounter.
 

eyewitness [ˋaɪˋwɪtnɪs] n. 目击者；见证人

hobbyist [ˋhɑbɪɪst] n. 业余爱好者

ANTHONY D`AMICO, OCEAN COUNTY SHERIFF`S DEPARTMENT: It was coming in our direction. It spun around 180 degrees, went back out the other way, then it

kind of looped around.
 

loop around 回路循环

CAMPBELL (voice-over): A task force of federal, state, and local law enforcement is now investigating, briefing concerned lawmakers Wednesday.
 

task force 专门小组；特别小组

Asked by CNN for comment on these sightings, the FBI said in the statement, "Witnesses have spotted the cluster of what look to be drones and a

possible fixed-wing aircraft." They`re asking anyone with information on the origin of these drones to call police.

(On camera): Now authorities say there`s no known threat to the public, but despite that, one congressman from New Jersey said that he`s been told

by sources that drones are being launched from an Iranian ship.

REP. JEFF VAN DREW (R-NJ): That mother ship is off, I`m going to tell you the deal, it`s off the east coast of the United States of America.

CAMPBELL: The Pentagon quickly shutting down those claims.

SABRINA SINGH, PENTAGON DEPUTY PRESS SECRETARY: There is not any truth to that. There is no Iranian ship off the coast of the United States and

there`s no so-called mother ship launching drones towards the United States.

WIRE: Pop quiz hot shot.

Through which state are sound waves unable to travel? Solids, liquids, a vacuum, or gases?

If you said vacuum, put your hands up. Sound waves need to travel through a medium, and there are no particles of matter present to vibrate or transmit

sound waves in a vacuum.

All right, if you could have any superpower, what would it be? Teleportation, invisibility, time travel? Might be a good question to ask
 

teleportation [ˌteləpɔˈteʃən] n.（想象中使用特别的科技或灵力而实现的）瞬移

each other and give your reasons why.

Well, if levitation is something that you think would be extraordinary, it may soon become ordinary. Scientists haven`t quite cracked the code on
 

levitation [͵lɛvəˋteʃən] n.（超自然力造成的）升空，飘浮

crack the code: to solve a difficult problem or mystery

moving objects with the mind, but they may be on to the next best thing. Moving objects with sound waves.

Our Nick Valencia shows us how a London-based startup is using sound to one day maybe revolutionize everyday practices in science.

(BEGIN VIDEOTAPE)

NICK VALENCIA, CNN CORRESPONDENT (voice-over): Levitating liquids and objects using just sound waves. Sounds out of the ordinary, even magical.
 

levitate [ˋlɛvə͵tet] v. 使..升空（或飘浮）

But a London-based startup says this could be revolutionary.

SRIRAM SUBRAMANIAN, ACOUSTOFAB CO-FOUNDER: We`ve been working on acoustic levitation for the last decade or decade and a half. We -- yes, we`ve
 

acoustic [əˋkustɪk] adj. 声学的

always been looking and exploring at ways in which we can float objects in mid-air using ultrasound.

And it was always a blue-sky idea until about a year ago when some of my co-founders were saying, oh, maybe there`s a commercial opportunity for
 

blue-sky idea (/thinking): creative ideas that are not limited by current thinking or beliefs

this.

VALENCIA: AcoustoFab has perfected the ability to pick up a droplet or a small particle, adjust it mid-air, then move it to a specific location
 

perfect [ˋpɝfɪkt] v. 使完美；改善，提高

doing all of this with only using sound waves.

The new technology uses a range of tiny speakers set at 40khz to generate the sound waves, outside of the audible range for humans.
 

speaker [ˋspikɚ] n. 扬声器，喇叭，扩音机

SUBRAMANIAN: The magic trick is we time the turning on and off of each individual speaker precisely. So when we turn them on and off at different

time intervals, they create a pattern and we can computationally using acoustic holography, shape the sound field in the far field however you want.
 

computationally [͵kɑmpjəˋteʃən!ɪ] adv. 从计算方面上讲

holography [həˋlɑgrəfɪ] n. 全像技术；全像摄影；雷射光摄影术

So for example, we can make them all come together to a point and they can we can make transducers from the bottom and from the top come to two
 

transducer [trænsˋdjusɚ] n. 传感器, 变频器

different points that are half a wavelength apart. Then if you put an object there, it`s going to be held in place.

VALENCIA: AcoustoFab has been demonstrating their sound levitation kit at tech fairs around the world. They say research labs can buy a basic kit for

academic use, starting at $3,100.

WIRE: When you think of professions that might require simulator training, maybe you`d think of airline pilots, special ops in the military, maybe a
 

simulator [ˋsɪmjə͵letɚ] n. 仿真训练装置

surgeon. Practicing critical skills in a controlled environment without real world risks has become a safe and reliable training method across a

number of professions.

Well, did you know that there is one city using simulator training for snowplow drivers? That`s right. The city of Nashville feels it`s important
 

snowplow [ˋsno͵plaʊ]n. 雪犁；除雪机

that their snowplow drivers down south are ready to roll even if there isn`t any snow to practice on.
 

down south【口】到南方; 在南方

CNN affiliate WSMV shows us why.

(BEGIN VIDEOTAPE)

UNIDENTIFIED FEMALE: Complete with power steering, plow control, and a salt spreader. It`s just like you`re driving a snowplow, but it`s all a

simulation.

UNIDENTIFIED MALE: I can kind of control all aspects of what`s going on in the cab right there. We can control day, night. It has ways on there we can

make it the road slicker, you know, sun glare.
 

slick [slɪk] adj. 光滑的；滑溜溜的; slippery

glare [glɛr] n. 刺眼的强光

UNIDENTIFIED FEMALE: It`s NDOT`s new technology that allows both new and experienced snowplow drivers a safe way to practice without wasting gas.

UNIDENTIFIED MALE: They can get up here and train and not, you know, not be burning fuel and then also not be putting them at risk of being on the

road, putting themselves at risk and putting, you know, everybody else in the road.

UNIDENTIFIED FEMALE: Safe enough that even we were allowed to test it out.

UNIDENTIFIED MALE: Now this controls your plow right here.

UNIDENTIFIED FEMALE: Scoring a barely passing 72 out of 100.

than 100,000 lights to help you have yourself a merry little Christmas.

And Rudolph the Red-Nosed Reindeer and friends, well they`re along for the ride helping to bring joy to the world. You see, CTA employees will deliver

around 400 holiday meal baskets to local charitable organizations. Slay all day.

All right, jolly old friends, it is time to close out this last show of 2024. We`ll be back January 6th. I`ll miss you during the winter break, so

follow me @coywire on Instagram and TikTok. I`ll be posting and replying, looking to share some holiday fun with all of you.

Now our last shout out of 2024 goes to Eleanor Roosevelt Middle School in Dubuque, Iowa. Dubuque the best.

Cue that Friday music, nadir. My team, we all wish you many blessings and hope you finish this year strong so we can take boundless energy into 2025.

Rise up. I`m Coy Wire and we are CNN 10.
