A new scientific breakthrough could dramatically improve cancer treatments by helping bulky, hard-to-deliver drugs enter cells more efficiently.

Researchers from Duke University, the University of Texas Health Science Center at San Antonio, and the University of Arkansas have discovered a way to significantly boost the cellular uptake of a promising class of cancer therapies known as PROTACs. These drugs work by degrading harmful proteins in cells but are often too large to penetrate cell membranes on their own.

The team found that a naturally occurring cell surface protein, CD36, can act as a transporter, helping PROTACs cross the cellular barrier. By modifying the drugs to exploit this transport mechanism, the researchers achieved up to 22.3 times higher drug uptake, resulting in up to 23 times more powerful tumor suppression—all without sacrificing drug stability or solubility. Their findings, published April 17 in Cell, could breathe new life into many large-molecule drugs previously deemed too unwieldy for therapeutic use.

The development of increasingly advanced sensors is driving progress in fields such as robotics, security systems, virtual reality (VR), and high-tech prosthetics. Among these, multimodal tactile sensors—which detect various types of touch-related data like pressure, texture, and material composition—stand out for their potential to replicate the human sense of touch.

Despite significant advances in tactile sensor technology, two major challenges persist: detecting both the direction and magnitude of applied forces, and accurately identifying the materials that objects or surfaces are made from. Many existing sensors struggle to overcome these limitations.

Researchers at the University of Tokyo have developed a new method for growing lab-cultured chicken meat that mimics natural blood vessel systems, offering a potential breakthrough in the production of realistic, ethical alternatives to conventional meat. The team successfully produced nugget-sized pieces of chicken muscle using a bioreactor equipped with artificial vessels that deliver nutrients and oxygen evenly throughout the tissue—one of the major challenges in lab-grown meat production.

The innovation centers on a device called a perfusable hollow fiber bioreactor, which uses tiny, tube-like structures to replicate the function of blood vessels. These artificial vessels not only keep the cells alive by providing a steady supply of oxygen and nutrients but also guide muscle cell growth through microscopic anchors that help align the tissue properly.

Researchers at the National University of Singapore have developed a novel system that can convert falling raindrops into usable electricity, enough to power 12 LEDs for 20 seconds. The innovation relies on a process called plug flow, where falling droplets move uniformly through a narrow vertical tube, maximizing the charge generated by each drop.

Led by Associate Professor Siowling Soh, the team demonstrated how this flow pattern significantly enhances the generation of electricity from water movement. Unlike conventional hydroelectric systems that require large-scale infrastructure and abundant water sources, this setup uses a simple, compact design involving a metallic needle and a 12-inch (32 cm) tall, 2-millimeter-wide polymer tube.

A team of researchers at Montana State University has created a novel living building material made from fungal mycelium and bacterial cells, capable of self-repair and extended viability. Unlike traditional construction materials, which are inert and resource-intensive, this bio-based composite remains alive and functional for weeks, offering a new frontier for sustainable and regenerative architecture.

The material is produced at low temperatures and incorporates living cells, drastically reducing the carbon footprint compared to conventional options like cement, which accounts for approximately 8% of global CO₂ emissions. According to lead researcher Dr. Chelsea Heveran, while the material is not yet strong enough to replace concrete in all structural applications, ongoing efforts aim to enhance its mechanical properties for broader use in the construction industry.

On a clear spring morning, a hiker tested the Hypershell exoskeleton—a wearable robotic leg brace designed to assist with walking and climbing—on Ben Nevis, the tallest mountain in the UK. Developed by Shanghai-based tech company Hypershell, the device uses AI-powered motors to reduce strain on the legs and enhance mobility, particularly on inclines and long treks.

Weighing approximately 4.4 pounds, the exoskeleton is worn around the waist and thighs and is powered by rechargeable batteries. It features three assistance modes—Eco, Transparent, and Hyper—which determine the level of support the motor provides. The system pairs with a smartphone app for control, though functionality may pose challenges for less tech-savvy users.

Neutrinos are among the most elusive and enigmatic particles in the universe. These ghost-like particles pass through matter—including our own bodies—almost entirely undetected. Yet, despite their abundance, much about neutrinos remains unknown, especially their mass. Unlocking this mystery is critical to deepening our understanding of both cosmology and fundamental particle physics, as even a tiny mass could point to new physics beyond the Standard Model.

At the forefront of this quest is the KATRIN experiment (Karlsruhe Tritium Neutrino), an international collaboration designed to make the most sensitive direct measurement of the neutrino’s mass. By observing beta decay—specifically the decay of tritium, a radioactive isotope of hydrogen—KATRIN analyzes the energy of electrons emitted in the process. Since energy conservation links the electron’s energy to that of the neutrino, any deviation can offer a precise estimate of the neutrino’s mass.
