Científicos dicen haber confirmado pruebas de que los humanos llegaron a América mucho antes de lo que se pensaba

Published Tue, 04 Mar 2025 21:36:59 GMT

(CNN) — Cuando en 2021 se hizo público el descubrimiento de huellas fosilizadas en lo que hoy es Nuevo México, la arqueología vivió un momento explosivo que parecía haber reescrito un capítulo de la historia de la humanidad. Ahora, nuevas investigaciones aportan más pruebas de su importancia.Aunque parece que podrían haber sido hechas ayer, las huellas fueron prensadas en el barro hace entre 21.000 y 23.000 años, según la datación por radiocarbono de las semillas de una planta acuática que se conservaron encima y debajo de los fósiles.Esta fecha hizo retroceder drásticamente la cronología de la historia de los humanos en América, la última masa continental en ser colonizada por pueblos prehistóricos. Las 61 huellas fechadas, que se descubrieron en la cuenca de Tularosa, cerca de la orilla de un antiguo lago del Parque Nacional de White Sands, se realizaron en una época en la que muchos científicos creen que las enormes capas de hielo habían sellado el paso de los humanos a Amé...

When should you switch to snow tires for the winter season?

Published Tue, 04 Mar 2025 21:36:59 GMT

DENVER (KDVR) — Freezing temperatures are almost here. Denver's forecast for Friday hits the upper 50s. While the warmth still lingers in early October, winter is on the way. As the cool weather moves in, it's time to start thinking about snow tires.For the Denver metro area, the rule of thumb is to switch to snow tires once temperatures drop consistently below 45 degrees, which happens quicker than you think, according to Skyler McKinley with AAA. How much snow could Denver get in October? While it can be around 80 degrees when the sun is up, it's below 50 degrees when the sun sets. Over the past five years in October, Denver has seen anywhere from trace amounts of snow to multiple inches. But it's not snow tire season just yet. Generally, McKinley marks the end of the leaf-peeping season as the time to put on snow tires. While it's still a little too early, appointments should be booked now, especially if you've never had snow tires before."You might want to make that appointmen...

EU climate chiefs back radical new 90 percent emissions target

Published Tue, 04 Mar 2025 21:36:59 GMT

Something quietly enormous occurred this week: The EU took a major step toward pledging to cut its greenhouse gas emissions by 90 percent by 2040, within a whisker of net zero before a child born today will finish school.The context was not promising. A fractious double hearing in the European Parliament where a former Shell oil company employee and a Slovakian with limited climate credentials were pitching for the two top jobs in global warming at the European Commission. But Dutchman Wopke Hoekstra and Slovak Maroš Šefčovič both pledged to “defend” a cut of “at least” 90 percent. They were then confirmed in their posts with the parliamentary committee’s approval. That sets a high bar for a legislative debate on the 2040 goal that is likely to preoccupy the EU next year. “The EU has and must continue to lead by example,” the pair said in a coordinated set of replies to the lawmakers. MEPs from the Greens in particular held up their approval until they had pers...

New treatment for Alzheimer’s disease shows promising signs in study by local researchers

Published Tue, 04 Mar 2025 21:36:59 GMT

A new treatment for Alzheimer’s disease is showing promising signs as researchers at Mass General Brigham recently found a monoclonal antibody treatment protected mice from proteins that cause the disease. Researchers published their study this week. Speaking with 7NEWS, one researcher discussed the origins of the work as well as the steps ahead. Doctors first studied individuals who were at high risk of getting Alzheimers but who did not get the disease. Doctors were then surprised at what they found in one subject.“By studying this one individual, we identified a gene that protected her and, inspired in that knowledge, we developed a new therapy that we hope can help other people that were not as lucky as her and don’t have that protected gene variant,” said researcher Dr. Joseph Arboleda-Velasquez.Researchers are optimistic they’re headed toward a cure and they hope everyone can use this antibody in the future. “My hope is that, if this new therapy is ...

Omar Apollo on his emotional new EP, ‘Live For Me,’ and ignoring the confines of genre

Published Tue, 04 Mar 2025 21:36:59 GMT

NEW YORK (AP) — In just four songs on his latest EP, “Live For Me,” Omar Apollo processes death, grief, acceptance and the lack of it — big, traumatic emotions — through intimate, lush sounds. The EP, out Friday, follows Apollo’s 2022 debut album “Ivory” and a 2023 Grammy nomination for best new artist. It’s also his first project since touring with SZA, and since his song “Evergreen (You Didn’t Deserve Me At All)” went viral on social media, bringing swaths of new listeners to his music.The singer-songwriter recently debuted the EP’s lead single at a show in London and went underground to preview the title track with TikTok’s latest sensation, “Tube Girl” Sabrina Bahsoon. Later this month, he’ll share New York’s Madison Square Garden stage with Daniel Caesar and Montell Fish at Caesar’s “Superpowers World Tour.”So, things are busy. But Apollo, 26, says all of it has felt productive, and inspiring. “I just feel like I’m doing and living. I feel alive now and … I th...

A look at the contenders for House speaker and the demands they’re facing from fellow Republicans

Published Tue, 04 Mar 2025 21:36:59 GMT

WASHINGTON (AP) — For Republicans, it’s a question with no clear answer: Who becomes House speaker after Kevin McCarthy?Despite former President Donald Trump’s endorsement of House Judiciary Chairman Jim Jordan of Ohio on Friday, it’s not at all certain that any of the GOP candidates will be able to round up enough votes — 218, if all lawmakers are present and voting — to ascend to one of the most powerful positions in government, second in line to the presidency. Jordan and a fellow longtime party stalwart and hard-liner, Majority Leader Steve Scalise of Louisiana, have begun making their case though phone calls and texts to colleagues.With the House trying to pick a new leader as soon as next week, others are waiting in the wings, including Oklahoma Rep. Kevin Hern, who as chair of the Republican Study Committee leads the largest faction of Republicans in the chamber.McCarthy’s chaotic election as speaker in January took 15 punishing rounds and left him in a weak...

Stock market today: Wall Street slips on worries that a too-hot job market will keep inflation high

Published Tue, 04 Mar 2025 21:36:59 GMT

NEW YORK (AP) — Worries about a too-hot job market are sending Wall Street lower Friday, keeping stocks on track to close out a fifth straight losing week.The S&P 500 was down 0.3% in morning trading and heading for its longest weekly losing streak in 16 months. The Dow Jones Industrial Average was down 117 points, or 0.4%, as of 10:30 a.m. Eastern time, and the Nasdaq composite was 0.1% lower.Once again, it was rising yields in the bond market pushing stocks lower. Yields leaped after a report said U.S. employers added nearly twice as many jobs last month as economists expected.Trading could be shaky through the day, though, as Friday’s jobs report also included some more encouraging nuggets for the inflation fighters at the Federal Reserve. Stocks pared their losses as the morning progressed.Strength in the job market is normally a good sign for financial markets because it means the economy is doing well and corporate profits can too. But in this new normal of high inflation,...
