Scientists Measure Meltwater on the Surface of the Greenland Ice Sheet

Scientists gather field data on the Greenland Ice Sheet to help verify climate models that are used to estimate future sea level rise and to incorporate the measurements into computer models that will create a simulation of the melt water runoff processes operating on the ice sheet. On Greenland’s ice sheet, a vast icy landscape […]

Physicists Use Cold Atoms to Probe Dark Energy

A team of physicists reproduced the low-density conditions of space to precisely measure dark energy, helping to reveal how strongly dark energy interacts with normal matter. Besides the atoms that make up our bodies and all of the objects we encounter in everyday life, the universe also contains mysterious dark matter and dark energy. The […]

This New Technology Could Transform Solar Energy Storage

Chemists at UCLA have developed a new technology that is capable of storing solar energy for up to several weeks — an advance that could change the way scientists think about designing solar cells. The materials in most of today’s residential rooftop solar panels can store energy from the sun for only a few microseconds […]

Diabetes Medicine Could Reduce Tumor Growth

Researchers from UCLA have identified a new mechanism that delivers glucose to cancer cells, providing evidence that drugs used to treat diabetes could be used to reduce tumor growth in pancreatic and prostate cancers. Cancer cells require high amounts of the sugar glucose to survive and grow, and long-standing research has established passive glucose transporters, […]

Researchers Identify Zebra-Like Stripes of Plasma in Space

A team of researchers from MIT and UCLA have identified zebra-like stripes of plasma in a region of space about 12,000 miles from Earth’s surface. The structure may help scientists identify radiation-remediation strategies in space. Since the early 1970s, orbiting satellites have picked up on noise-like plasma waves very close to the Earth’s magnetic field […]

Nanoparticles Shut Down Cancer Growth

Using nanoparticles to deliver a nucleic acid (siRNA) into tumor cells in mouse models, scientists from UCLA and City of Hope have become the first to inhibit the mechanism that drives cancer growth. When scientists develop cancer therapies, they target the features that make the disease deadly: tumor growth, metastasis, recurrence and drug resistance. In […]

Engineers Demonstrate a New Way to Harness Light Particles

By slicing up and entangle each photon pair into multiple dimensions, researchers from UCLA have demonstrated a new way to harness light particles. A team of researchers led by UCLA electrical engineers has demonstrated a new way to harness light particles, or photons, that are connected to each other and act in unison no matter […]

Study Reveals Bone-Building Protein’s Impact on Bone Stem Cells

In a newly published study, scientists from UCLA reveal that the protein NELL-1 stimulates significant bone formation through the regenerative ability of stem cells. These preclinical results could one day have an impact on the development of a treatment for osteoporosis, which affects more than 200 million people worldwide, as well as potentially help those […]

New Device Delivers Nanoparticles at the Rate of 100,000 Cells Per Minute

A newly developed device can deliver nanoparticles, enzymes, antibodies, bacteria and other “large-sized” cargo into mammalian cells at speeds up to 100,000 cells per minute. A new device developed by UCLA engineers and doctors eventually help scientists study the development of disease, enable them to capture improved images of the inside of cells and lead […]

Stars Forming in a Nearby Galaxy

An international team discovers a remarkable star cluster where more than a million young stars are forming in a hot, dusty cloud of molecular gases. The star cluster is buried within a supernebula in a dwarf galaxy known as NGC 5253, in the constellation Centaurus. The cluster has one billion times the luminosity of our […]

New Image of the Pillars of Creation

A new study from UCLA physicists offers a possible solution to the mystery of the origin of matter in the universe. Most of the laws of nature treat particles and antiparticles equally, but stars and planets are made of particles, or matter, and not antiparticles, or antimatter. That asymmetry, which favors matter to a very […]

Scientists Discover Organism That Hasn’t Evolved

Scientists from UCLA have discovered an organism that hasn’t evolved in more than 2 billion years. An international team of scientists has discovered the greatest absence of evolution ever reported — a type of deep-sea microorganism that appears not to have evolved over more than 2 billion years. But the researchers say that the organisms’ […]

Gullies Suggest Past Water on Vesta

A newly published study shows evidence that transient water flowed on the surface of Vesta, in a debris-flow-like process, and left distinctive geomorphologic features. Protoplanet Vesta, visited by NASA’s Dawn spacecraft from 2011 to 2013, was once thought to be completely dry, incapable of retaining water because of the low temperatures and pressures at its […]

Rivers of Glacial Meltwater Are Draining Greenland Quickly

Using satellite and field work after an extreme melt event in Greenland, new research shows that melt-prone areas on the ice sheet develop a remarkably efficient drainage system of streams and rivers that carry meltwater into moulins (sinkholes) and ultimately the ocean. As the largest single chunk of melting snow and ice in the world, […]

How Microbial Dark Matter Might Cause Disease

A landmark discovery reveals new insights on the biological, ecological and medical importance of TM7, and could lead to better understanding of other elusive bacteria. One of the great recent discoveries in modern biology was that the human body contains 10 times more bacterial cells than human cells. But much of that bacteria is still […]
