Jeep is launching an electric Renegade for under $25,000

Posted by in category: transportation

An all-electric Jeep Renegade is finally confirmed. Even better, it will start at under $25,000 as Jeep expands into new markets. In the US, the Jeep Renegade EV will join two other all-electric Jeep vehicles, the Wagoneer S and Wangler-inspired Recon.

The news was confirmed during Stellantis 2024 Investor Day on Thursday. Jeep’s electric Renegade will be among three new EVs launching in North America.

Although Jeep was recently voted America’s most patriotic brand, sales have slipped over the past few years. After sales quadrupled in the US, reaching nearly 1 million in 2018, Jeep has struggled to gain momentum.

Tesla clears another hurdle to launching full self-driving in China

Posted by in categories: mapping, robotics/AI, transportation

Hong Kong (CNN) — Tesla is one step closer to launching full-self driving (FSD) technology in China after it clinched an agreement with Baidu to upgrade its mapping software.

The Chinese tech giant said Saturday that it was providing lane-level navigation services for Tesla cars. Baidu (BIDU) says this level of navigation can provide drivers with detailed information, including making lane recommendations ahead of upcoming turns, to enhance safety.

Dark matter turns out to be an echo of a parallel Universe

Posted by in categories: cosmology, particle physics, quantum physics

The study is based on several intriguing coincidences. First, observations show that there is about the same amount of ordinary and dark matter, which exceeds baryonic by about five times. And secondly, neutrons and protons have almost the same mass, which allows them to form stable atoms — this is a random but stable property of the quantum world, because otherwise our universe would not be home to any of the atoms that make up stars, planets and ourselves.

In fact, the theory suggests that there may be a parallel universe like ours in which neutrons and protons do not have such convenient symmetry in mass. In this world, there is a “soup” of subatomic particles that interact little, which explains why dark matter does not seem to clump together.

It is important to note that this is just one more of many hypotheses that try to explain the mystery of dark matter – an annoying and lingering unknown in our understanding of the universe.

Why many lung cancer patients who have never smoked have worse outcomes

Posted by in categories: biotech/medical, genetics

The reason targeted treatment for non-small cell lung cancer fails to work for some patients, particularly those who have never smoked, has been discovered by researchers from UCL, the Francis Crick Institute and AstraZeneca.

The study, published in Nature Communications, shows that lung cancer cells with two particular genetic mutations are more likely to double their genome, which helps them to withstand treatment and develop resistance to it.

In the UK, lung cancer is the third most common type of cancer and the leading cause of cancer death. Around 85% of patients with lung cancer have (NSCLC), and this is the most common type found in patients who have never smoked. Considered separately, “never smoked” lung cancer is the fifth-most common cause of cancer death in the world.

New Transformer architecture could enable powerful LLMs without GPUs

Posted by in category: computing

The researchers compared two variants of their MatMul-free LM against the advanced Transformer++ architecture, used in Llama-2, on multiple model sizes.

Interestingly, their scaling projections show that the MatMul-free LM is more efficient in leveraging additional compute resources to improve performance in comparison to the Transformer++ architecture.

The researchers also evaluated the quality of the models on several language tasks. The 2.7B MatMul-free LM outperformed its Transformer++ counterpart on two advanced benchmarks, ARC-Challenge and OpenbookQA, while maintaining comparable performance on the other tasks.
