Entanglement Goes Steady

Two independent groups have demonstrated ways to entangle quantum bits without the need for precisely timed control pulses.

Quantum entanglement describes a link, or correlation, between the states of two or more quantum particles. For example, given a pair of entangled qubits—particles that can be in either a ground state or an excited state—measuring the state of one qubit can inform us about the state of the other. Entanglement is puzzling because it has no analogue in the classical world, where our physical intuition can be relied upon. In particular, entanglement appears to violate the principle of locality: The qubits’ states remain correlated even if we move them far apart before measuring them. But entanglement is more than a curiosity: It is also critical to quantum computing, where it serves as a resource for performing quantum algorithms and remote operations between distant qubits.

Can We Re-grow You?

For all of medical history, we’ve tried to persuade sick cells to behave better. What if instead we just swapped them out? Can we insert new brain cells grown from your own skin cells? And what does any of this have to do with sending one’s own cells into space, or rescuing animals on the very brink of extinction? Today Eagleman talks with stem cell biologist Jeanne Loring about the exciting next horizons.

A helpful review on immunological responses to adenoviral vectors, a widely used delivery system for gene therapies, anti-tumor therapies, and vaccines.

Adenovirus (AdV) is one of the most widely used vectors for gene therapy and vaccine studies due to its excellent transduction efficiency, capacity for large transgenes, and high levels of gene expression. When administered intravascularly, the fate of AdV vectors is heavily influenced by interactions with host plasma proteins. Some plasma proteins can neutralize AdV, but AdV can also specifically bind plasma proteins that protect against neutralization and preserve activity. This review summarizes the plasma proteins that interact with AdV, including antibodies, complement, and vitamin K-dependent coagulation factors. We will also review the complex interactions of these plasma proteins with each other and with cellular proteins, as well as strategies for developing better AdV vectors that evade or manipulate plasma proteins.

Nobel laureates among more than 200 experts urging action on AI’s economic impact

More than 200 researchers and economists, including 15 Nobel laureates and researchers at OpenAI, Anthropic and Google, have called for governments and technology leaders ‌to urgently create policies and institutions to address the economic impact of AI.

Battery-like device pulls CO₂ from air using electricity and saltwater chemistry

Engineers have developed a new way to pull carbon dioxide directly from the atmosphere using a process similar to charging and discharging a battery—an advance that could help address the planet’s excess CO2 problem.

A new collaborative study between scientists at the University of Illinois Urbana-Champaign and Toyota focuses on direct air capture, a technology designed to reduce new emissions and remove CO2 that has already accumulated in the atmosphere. Instead of using heat to absorb and release CO2, as many carbon capture methods do, the new method uses electricity and water-based chemistry within an electrochemical device.

The results of the study by mechanical engineering and science professor Kyle Smith, Illinois graduate students Paul Rozzi and JeongA Lee, and Chip Roberts and Tim Arthur from the Toyota Research Institute of North America are published in the journal Environmental Science & Technology.

Dead stars in our cosmic backyard: Astronomers spot four white dwarfs hiding under our noses

Researchers at the University of Warwick and the University of Colorado Boulder have directly observed, for the first time, four white dwarfs in binary star systems in our nearby region of space. These stellar binaries are all within 65 light-years of Earth, and one contains the ninth-closest white dwarf to the sun.

The four systems each include a red dwarf companion—a larger, brighter star—making the systems appear to be single-star systems. The new results, published in MNRAS, show that each of these nearby red dwarfs hosts a hidden white dwarf companion.

First author Dr. Mairi O’Brien, a research fellow at the University of Warwick, said, “Nearby isolated white dwarfs are usually easy to find, but we couldn’t see these four stars directly in visible wavelengths because their red dwarf companions were drowning out their light. It’s a reminder that even in our own cosmic neighborhood, we can still find surprises if we look in the right way, at the right wavelengths.”

Apple files lawsuit accusing ChatGPT maker OpenAI of stealing trade secrets

Sam Altman has repeatedly suggested that today’s smartphones are not the ideal interface for advanced AI. The ambition is to create what some observers describe as an “AI-native” device—one that could eventually become as important as the smartphone itself.

Apple on Friday accused OpenAI of stealing trade secrets as it seeks to build its own hardware for ChatGPT, a major rupture in a partnership between the iPhone maker and the artificial intelligence company.

Apple said in the lawsuit filed in a California federal court that OpenAI encouraged Apple employees it was recruiting to share confidential information, even guiding how to avoid scrutiny when taking jobs at the other company.

“This case is about Apple’s former employees stealing Apple’s trade secrets for the benefit of OpenAI,” the filing says. “Apple brings this suit to put a stop to it.”
