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.

Study Offers New Detail on how COVID-19 Affects the Lungs

Posted by in category: biotech/medical

New research shows that ferroptosis, a form of cell death, occurs in severe COVID-19 patient lungs. Stopping it improves outcomes. In some severe cases of COVID-19, the lungs undergo extreme damage, resulting in a range of life-threatening conditions like pneumonia, inflammation, and acute respiratory distress syndrome. The root cause of those wide-ranging reactions in the lungs has until now remained unclear.

A new study by researchers at Columbia and the Columbia University Irving Medical Center sheds light on this mystery.

The study found that ferroptosis, a form of cell death first named and identified at Columbia in 2012, is the major cell death mechanism that underlies COVID-19 lung disease.
