Scientists have discovered that over half a mile of DNA could hold over 360,000 terabytes of data.
Quantum computers will need large numbers of qubits to tackle challenging problems in physics, chemistry, and beyond. Unlike classical bits, qubits can exist in two states at once—a phenomenon called superposition. This quirk of quantum physics gives quantum computers the potential to perform certain complex calculations better than their classical counterparts, but it also means the qubits are fragile. To compensate, researchers are building quantum computers with extra, redundant qubits to correct any errors. That is why robust quantum computers will require hundreds of thousands of qubits.
Now, in a step toward this vision, Caltech physicists have created the largest qubit array ever assembled: 6,100 neutral-atom qubits trapped in a grid by lasers. Previous arrays of this kind contained only hundreds of qubits.
This milestone comes amid a rapidly growing race to scale up quantum computers. There are several approaches in development, including those based on superconducting circuits, trapped ions, and neutral atoms, as used in the new study.
The neutral-atom platform shows promise for scaling up quantum computers.
Heat is one therapy to help damage and kill cancer cells, according to the National Cancer Institute. Steam offers a targeted way to deliver heat into the body, according to Abreu.
Before the procedure, physicians use magnetic resonance imaging (MRI) to locate the tumor cells in the patient’s prostate. During the procedure, doctors use an ultrasound and prostate mapping to guide a thin catheter through the patient’s urethra and into the area of the prostate where the tumor is located.
Once the catheter is positioned, a fine needle is deployed in the tumor. Doctors then release a quick, targeted 10-second burst of steam from the needle, and more bursts as needed, to destroy the tumor.
‘This procedure is thought to be much gentler on the body than traditional therapies and is designed to target the cancerous tissue within the prostate,’ said Abreu. ‘We are exploring if steam may be effective at destroying cancer cells without damaging the surrounding organs.’

Alzheimer’s disease (AD) is a neurodegenerative disease marked by the accumulation of toxic amyloid-beta (Aβ) oligomers. These oligomers are thought to cause synaptic dysfunction and contribute to neurodegeneration. CT1812 is a small-molecule sigma-2 receptor antagonist that is currently being investigated and tested as a potential disease-modifying treatment for AD. CT1812 acts by displacing Aβ oligomers into the cerebrospinal fluid and preventing their interaction with receptors on neurons. Preclinical studies and early clinical trials of CT1812 show promising results and provide evidence for its potential to slow AD progression. This review outlines the role of Aβ oligomers in AD, CT1812’s mechanism of action, and the effectiveness and limitations of CT1812 based on preclinical and clinical studies.
People who treat others with compassion often feel more at ease themselves. This is the key finding of a new study by Majlinda Zhuniq, Dr. Friedericke Winter, and Professor Corina Aguilar-Raab from the University of Mannheim. Their study was recently published in the journal Scientific Reports.
While the link between self-compassion and well-being is well established, this effect has hardly been researched with respect to compassion for others. In a meta-analysis, the research team analyzed data from more than 40 individual studies.
The results showed that people who empathize with others, support them, or want to help them report greater overall life satisfaction, experience more joy, and see more meaning in life. On average, these people’s psychological well-being was higher. The link between compassion and a reduction in negative feelings, such as stress or sadness, was weaker. However, slight positive trends could also be seen in this respect.
Gemini North captured new images of Comet 3I/ATLAS after it reemerged from behind the sun on its path out of the solar system. The data were collected during a Shadow the Scientists session—a unique outreach initiative that invites students around the world to join researchers as they observe the universe on the world’s most advanced telescopes.
On 26 November 2025, scientists used the Gemini Multi-Object Spectrograph (GMOS) on Gemini North at Maunakea in Hawai’i to obtain images of the third-ever detected interstellar object, Comet 3I/ATLAS. The new observations reveal how the comet has changed after making its closest approach to the sun. Gemini North is one half of the International Gemini Observatory and operated by NOIRLab.
After emerging from behind the sun, 3I/ATLAS reappeared in the sky close to Zaniah, a triple-star system located in the constellation Virgo. These observations were taken as part of a public outreach initiative organized by NOIRLab in collaboration with Shadow the Scientists, an initiative created to connect the public with scientists to engage in authentic scientific experiments, such as astronomy observing experiences on world-class telescopes. The scientific program was led by Bryce Bolin, a research scientist from Eureka Scientific.
The microscopic processes taking place in superconductors are difficult to observe directly. Researchers at the RPTU University of Kaiserslautern-Landau have therefore implemented a quantum simulation of the Josephson effect: They separated two Bose-Einstein condensates (BECs) by means of an extremely thin optical barrier.
The characteristic Shapiro steps were observed in the atomic system. The research was published in the journal Science.
Two superconductors separated by a wafer-thin insulating layer—that’s how simple a Josephson junction looks. But despite its simple structure, it harbors a quantum mechanical effect that is now one of the most important tools of modern technology: Josephson contacts form the heart of many quantum computers and enable high-precision measurements—such as the measurement of very weak magnetic fields.
