Artemis I moon rocket is a step closer to launch countdown

Essentially the most highly effective rocket NASA has ever constructed, the Area Launch System is now prepared for a ultimate prelaunch take a look at for the uncrewed Artemis I mission. Generally known as a moist gown rehearsal, the trial contains loading the gasoline tanks and conducting a launch countdown.

In the end, the plan is to make use of the 322-foot (98-meter) rocket to land the primary girl and individual of coloration on the moon. The SLS will usher in a brand new period of deep area exploration.

However at the same time as NASA reaches for the celebrities, I used to be struck this week by how a lot of Earth’s floor nonetheless stays uncharted and the way dramatically it could change with out us figuring out.

I am Katie Hunt, standing in for Ashley Strickland on this version of Surprise Principle.

Ocean secrets and techniques

Marine scientists have found deep sinkholes — one bigger than a metropolis block of six-story buildings — and ice-filled hills which have shaped “terribly” quickly on a distant a part of the Arctic seafloor.

Mapping of Canada’s Beaufort Sea revealed the dramatic adjustments, which the researchers mentioned are happening because of thawing permafrost submerged beneath the seabed.

It is the primary time subsea permafrost has been tracked on this manner, and scientists mentioned it was shocking to see adjustments like these occurring in such a brief span of time — lower than a decade.

Permafrost is a frozen layer of earth, and it covers 1 / 4 of the Northern Hemisphere, together with beneath the ocean. Massive swaths of permafrost have been submerged as glaciers melted and sea ranges rose on the finish of the final ice age, round 12,000 years in the past.

On land, hotter temperatures have led to radical shifts within the Arctic panorama lately. Human-caused local weather change, nonetheless, did not induce these shifts within the seabed, the researchers mentioned.

Wild kingdom

When a pack of big hornets assaults a honeybee hive, the slaughter is brutal and fast. The marauders — generally described as homicide hornets — can decimate a hive in hours.

Whereas Asian bees have tailored to guard themselves from the predatory hornets, North American bees haven’t.

Researchers in China have discovered a strategy to lure the hornets into traps — doubtlessly stopping the unfold of the invasive species. Their secret weapon would possibly shock you. Trace: It includes the sport of attraction.

Penalties

Pollen seasons are increasing in length and intensity.

Allergy symptoms are way over a sneezy seasonal annoyance — hay fever could be tremendous disruptive to on a regular basis life. It is also an issue that is being exacerbated by the local weather disaster.

By the tip of the century, the pollen season might start as a lot as 40 days sooner than it has in latest a long time within the US due to local weather crises, in line with new analysis. Annual pollen counts might climb by as much as 250%.

Sometimes, completely different timber similar to birch, oak and pine launch pollen at completely different instances. However hotter and earlier spring climate signifies that completely different pollen varieties will overlap, making the pollen season extra intense.

Discoveries

Ewww. It seems your kitchen sponge can develop micro organism higher than a petri dish in a lab.

A sponge’s spatial partitioning — the way in which it is divided into completely different sectors of varied sizes — means it is a paradise for micro organism that thrive in secluded areas, in line with a brand new examine.

The purpose of the analysis is to assist scientists higher perceive habitats favored by microbial communities that might produce chemical compounds of medicinal worth, however they did share some tips about tips on how to hold your kitchen sponge comparatively germ-free.

Defying gravity

NASA astronaut Raja Chari is pictured tethered to the International Space Station during a six-hour and 54-minute spacewalk on March 15.
The astronauts on board the Worldwide Area Station are defying gravity … and politics.
The primary spacewalk of the yr befell outdoors the area station on Tuesday, whereas on Friday three new Russian crew members have been welcomed aboard, becoming a member of the 4 Individuals, one European and two Russians already there.

With Russia’s invasion of Ukraine, the cosmonauts’ arrival on the area station comes at a time of mounting geopolitical tensions which have seen former US astronaut Scott Kelly conflict on Twitter with the top of Roscosmos, the Russian area company.

Such assaults are “damaging” to the area station’s mission, a NASA official has warned. The company mentioned it is nonetheless working carefully with Roscosmos, and NASA astronaut Mark Vande Hei will “for certain” return from the ISS later this month aboard a Russian Soyuz spacecraft, as beforehand deliberate.

The surprise

Do not miss these eye-popping tales:

— Beneath Notre Dame cathedral in Paris, archaeologists have made a shocking discovery that might date to the 14th century.
A brand new species of armored dinosaur has been unearthed in southwestern China, and it has related options to a porcupine.
— Relaxation simple. NASA’s asteroid surveillance web received to flex its muscle tissues in actual time this week — and it is doing its job.

Tornado Confirmed in Northern California

Tornado Confirmed in Northern California

A winter storm in Northern California spawned a tornado on Friday, setting off a warning for people to seek shelter urgently.

The tornado was confirmed around 5:30 p.m. local time near Paynes Creek and Shingletown, the National Weather Service’s Sacramento office said in an alert on Friday. A tornado warning, which indicates an imminent life-threatening danger, was active until 6 p.m., the alert said.

The Weather Service shared a video captured by the University of California, San Diego, of a tornado passing a grassy area.

The warning urged residents to take cover because flying debris and damage to property was expected. The alert covered parts of Tehama and Shasta counties with an estimated population of 2,200 people, according to the Weather Service.

A winter storm that brought heavy snow and strong wind gusts spawned the tornado, said Katrina Hand, a meteorologist with the National Weather Service. There were no reports of injuries or damage, she added. A winter storm warning was active throughout the day, with eight to 12 inches of snow in areas above 5,500 feet and quarter-size hail forecast.

Tornadoes are not uncommon for that part of California and the storms in the region this time of year, Ms. Hand said. She added that the state averages about 10 tornadoes annually, most commonly in the northern half of the Central Valley, where the tornado was observed on Friday.

Less than a month earlier, the National Weather Service issued its first-ever tornado warning for San Francisco. The city was spared, but one touched down in nearby Santa Cruz County, where it downed power lines and caused vehicle crashes.

US stocks rally to shake off new year jitters amid light trading

US stocks rally to shake off new year jitters amid light trading

Stay informed with free updates

Stocks on Wall Street rallied on Friday to close out the first week of 2025 on an upbeat note amid fresh signs of manufacturing stability, bringing a halt to several days of losses.

The S&P 500 closed the day 1.3 per cent higher, posting its biggest rise since November 6 — the day after Donald Trump’s US election victory. The benchmark index’s gains on Friday also brought an end to five consecutive days of losses — the longest such streak since April.

The technology-heavy Nasdaq Composite added 1.8 per cent, helped by a rise of more than 8 per cent for electric-vehicle maker Tesla, whose shares had slipped a day earlier after announcing its first decline in annual vehicle deliveries in more than a decade. Semiconductor giant Nvidia advanced more than 4 per cent.

The gains came at the end of a week shortened by New Year’s Day, which can bring thinner trading volumes. Analysts noted some investors were simply preparing for the “real” start to 2025 on Monday.

But the day’s share price moves also came as a fresh reading on US manufacturing activity topped consensus forecasts, bolstering investor sentiment, and as Trump ally Mike Johnson was re-elected as Speaker of the US House of Representatives.

“It’s really a combination — I’ll call it a potpourri of different factors,” said Kristina Hooper, chief global markets strategist at Invesco. “First of all, we have seen some selling — and so at a certain point, I think investors recognise that there are buying opportunities created when you have multiple days of sell-offs.”

At the same time, Hooper added: “We got some good news today in terms of manufacturing [figures] and I think that certainly set a positive tone. We had a relatively smooth election in the House that also helped contribute to more positive sentiment.”

The ISM manufacturing purchasing managers’ index reading on Friday landed at 49.3 for December — below the threshold of 50 that marks expansion, but above economists’ forecasts and higher than a reading of 48.4 for November.

“The S&P 500 saw a broad rally as [investors] took comfort from the orderly re-election of the US House Speaker, as that helps reduce political uncertainty,” said Dec Mullarkey, managing director at SLC Management.

Referring to the group of Big Tech names that have come to dominate the US stock market, he added “the Magnificent Seven, in particular, remain resilient even as valuations run high. Investors are still confident that the large outlays for [artificial intelligence] investment will pay dividends and secure a first-mover advantage.”

Even after Friday’s sharp rise, the S&P and Nasdaq still posted small weekly losses.

Invesco’s Hooper believed that “the overall environment is supportive of risk assets”, meaning “we’re likely to have more positive days than negative days” as the new year progresses. However, “there could very well be more volatility”, she said.

“Let’s face it: there’s more uncertainty, and as we get closer and closer to January 20 [the day of Trump’s inauguration] I think there will be more question marks around what’s likely to come from the new administration.”

Driver of exploding Cybertruck left letters of anguish: 'I needed to cleanse my mind'

Driver of exploding Cybertruck left letters of anguish: 'I needed to cleanse my mind'

A Green Beret who drove an explosives-laden Tesla Cybertruck to Las Vegas and detonated its payload at Trump International Hotel left a suicide note saying the spectacle was intended as a “wake up call” for America and was not intended as an act of terrorism, according to authorities.

“This was not a terrorist attack,” wrote Matthew Livelsberger, who police say fatally shot himself before Wednesday’s explosion. “It was a wake up call. Americans only pay attention to spectacles and violence. What Better way to get my point across than a stunt with fireworks and explosives?”

At a Friday news conference in Las Vegas, local and federal law enforcement officials released portions of a notes and letters that suggested the former Army master sergeant and Afghanistan war veteran was partly motivated by his experiences in combat, as well as his view of political events unfolding in the United States.

“Why did I personally do it it now? I needed to cleanse my mind of the brothers I’ve lost and relieve myself of the burden of the lives I took,” the 37-year-old wrote.

Suicide prevention and crisis counseling resources

If you or someone you know is struggling with suicidal thoughts, seek help from a professional and call 9-8-8. The United States’ first nationwide three-digit mental health crisis hotline 988 will connect callers with trained mental health counselors. Text “HOME” to 741741 in the U.S. and Canada to reach the Crisis Text Line.

Authorities have not released the soldier’s complete writings recovered on a cellphone found inside the destroyed vehicle.

“These are just excerpts,” Las Vegas Metropolitan Police Department Assistant Sheriff Dori Koren said.

“He does offer additional information that is varying on the spectrum in terms of political grievances, issues about conflicts elsewhere — not here — domestic issues, societal issues … including personal challenges as well,” Koren said.

The New Year’s Day blast came hours after a terrorist attack in New Orleans, where an Army veteran drove another truck through a crowded street, killing 14 and injuring about 30 others.

Given that both attacks appeared to be ideologically motivated, authorities wondered initially whether the two events might be connected. Investigators have since determined that the New Orleans attacker acted alone.

Among other writing excerpts released Friday were passages in which Livelsberger expressed frustration with the nation’s direction.

“Fellow servicemembers, veterans and all Americans. TIME TO WAKE UP! We are being led by weak and feckless leadership who only serve to enrich themselves”

He also wrote that also that the United States was the best country “to ever exist! But right now we are terminally ill and headed toward collapse.”

Livelsberger served as a Green Beret master sergeant in the Army. He spent the majority of his time at Ft. Carson in Colorado and in Germany, according to authorities. He was on approved leave from Germany at the time of his death.

On his Facebook profile, Livelsberger once criticized the withdrawal of U.S. armed forces from Afghanistan in 2021. He called it the “biggest foreign-policy failure in the history of the United States.”

Times staff writers Summer Lin, Hannah Fry, Richard Winton and Terry Castleman contributed to this report.
