Multifocus microscope pushes the limits of fast live 3D biological imaging

Researchers have developed a high-speed 3D imaging microscope that can capture detailed cell dynamics of an entire small whole organism at once. The ability to image 3D changes in real time over a large field of view could lead to new insights in developmental biology and neuroscience.

“Traditional microscopes are constrained by how quickly they can refocus or scan through different depths, which makes it difficult to capture fast, 3D without distortion or missing information,” said Eduardo Hirata Miyasaki, who performed the work while in Sara Abrahamsson’s lab at the University of California Santa Cruz (UCSC) and is now at the Chan Zuckerberg Biohub.

“Our new system extends the multifocus microscopy (MFM) technique Abrahamsson developed by using a 25-camera array to push the limits of speed and volumetric imaging. This leap in efficiency opens the door to studying small living systems in motion without disrupting them.”

Inspired by Death Valley, researchers mimic a mystery of nature to make ice move on its own

In Associate Professor Jonathan Boreyko’s Nature-Inspired Fluids and Interfaces Lab, Ph.D. student Jack Tapocik watched a disk-shaped chunk of ice resting on an engineered metal surface. As the ice melted, the water formed a puddle beneath.

Even after many seconds of melting, the ice disk remained adhered to the engineered surface. At first, Tapocik was tempted to conclude that nothing would happen, but he waited. His patience paid off. After a minute, the ice slingshot across the metal plate he designed, gliding along as if it was propelled supernaturally.

The results are important because they have a host of potential applications. The methods team members developed lay the foundation for rapid defrosting and novel methods of energy harvesting. Their work has been published in ACS Applied Materials & Interfaces.

What Are the Rules of the Universe? Google’s Quantum Computer Is Finding Out

Researchers used Google’s quantum processor to simulate fundamental physics, offering a new way to study the universe’s basic forces and particles. The fundamental forces that shape our universe are explained through intricate theoretical models. These models are notoriously difficult to study be

A Glimpse of New Physics? ATLAS Edges Closer to Unlocking Higgs Boson Secrets

The ATLAS collaboration has reported evidence for Higgs bosons decaying into muons and has enhanced the ability to detect Higgs boson decays involving a Z boson and a photon. At the 2025 European Physical Society Conference on High Energy Physics (EPS-HEP) in Marseille, France, research on the Hi

It’s Official: ‘Ghost Particle’ That Smashed Into Earth Breaks Records

The verdict is in. The detection of a cosmic neutrino that smashed into Earth with an unprecedented energy level is not a glitch or an error, but a real detection of a real particle.

In February 2023, a detector called KM3NeT, located deep under the Mediterranean Sea, picked up a signal that seemed to indicate a neutrino with a record-shattering energy of 220 petaelectronvolts (PeV). For reference, the previous record was a mere 10 PeV.

Now, an exhaustive analysis of all the data on and around the event, designated KM3-230213A, not only supports the conclusions that the signal was caused by a 220-PeV neutrino, but adds to the mystery about where the heck in the Universe it came from.

Star Trying to Swallow a Black Hole May Have Triggered a New Type of Supernova

In 2023, astronomers recorded one of the most extraordinary space explosions they had ever seen.

It took place some 750 million light-years away, flaring into the detectors of the Zwicky Transient Facility on 7 July. At first, it looked just like a normal supernova – the explosive death of a star – and astronomers named it SN 2023zkd.

Six months later, a search for cosmic anomalies flagged the explosion as a little odd. A look back at data collected since its initial discovery revealed SN 2023zkd had done something really weird: it brightened again.

New HTTP/2 ‘MadeYouReset’ Vulnerability Enables Large-Scale DoS Attacks

This attack is notable not least because it obviates the need for an attacker to send an RST_STREAM frame, thereby completely bypassing Rapid Reset mitigations, and also achieves the same impact as the latter.

In an advisory, the CERT Coordination Center (CERT/CC) said MadeYouReset exploits a mismatch caused by stream resets between HTTP/2 specifications and the internal architectures of many real-world web servers, resulting in resource exhaustion — something an attacker can exploit to induce a DoS attack.
