NASA Detects Movement in Martian Sand Dunes

Advancing Dune in Nili Patera, Mars

Over the last two years researchers have been monitoring the sand movement on Mars with the HiRISE camera. They found that even with a thinner atmosphere and less high-speed wind, movement in sand dune fields occurs at about the same rate as in dune fields on Earth. Pasadena, California — NASA’s Mars Reconnaissance Orbiter has […]

Flavonoid Compound Shown to Prevent Blood Clots

therapeutic agent to prevent stroke, heart attack

Newly published findings from the Beth Israel Deaconess Medical Center describe how rutin was shown to inhibit the formation of blood clots in an animal model of thrombosis. Found in fruit, vegetables and over the counter supplements, this flavonoid proved to be a potent anti-thrombotic compound, inhibiting both platelet accumulation and fibrin generation during thrombus […]

Support for Climate Change Policies Dwindling

'Blue Marble' Image of the Earth

A new Stanford survey suggests that support for policies intended to reduce future climate change has dropped by 10 percent over the last two years. Americans’ support for government action on global warming remains high but has dropped during the past two years, according to a new survey by Stanford researchers in collaboration with Ipsos […]

Portable Diagnostics Use Vibration to Move Drops of Liquid

engineers try to shrink diagnostics

Scientists at the University of Washington are using nanotechnology manufacturing techniques to build and refine portable diagnostics that have surfaces with tiny posts of varying height and spacing. When shaken, the surface moves drops along certain paths to conduct medical or environmental tests. As medical researchers and engineers try to shrink diagnostics to fit in […]

Tidal Heating Suggests Less Habitable Planets

tidal-forces-heating-red-dwarf

Tidal heating, which is basically gravitational heating of a planet via tides, suggests that the number of habitable planets could be roughly half of what was previously thought. Tidal heating could shrink the habitable zone around the Milky Way’s most numerous stars, red dwarfs. Rory Barnes, an astrobiologist at the University of Washington in Seattle, […]

HDL Cholesterol Isn’t Always Good for Your Heart

Some HDL may not protect against heart disease

Contrary to popular belief, HDL cholesterol isn’t always good for your heart. A new study published by Harvard researchers describes how some high-density lipoprotein (HDL) cholesterols may contain a small protein, apolipoprotein C-III, which increases the risk of heart disease. A new study by Harvard School of Public Health (HSPH) researchers has found that a […]

Diminutive Mammoth Roamed Crete in the Pleistocene

mini-mammoth-size-comparison

Researchers have discovered by studying fossils on the island of Crete in the Mediterranean Sea that an extinct species of dwarf elephant was actually the smallest mammoth known to have existed. As an adult, Mammuthus creticus would stand no taller than a modern newborn elephant. M. creticus is supposed to be an extreme form of island […]

New Drug Fights Cancer by ‘Hijacking’ Existing T Cells

killing of three melanoma cells by a single non-cancer-specific Tcell

A new study describes how a team of researchers are exploring ways to manipulate the body’s existing T cells that normally kill viruses and redirect them to kill cancer cells instead. By engineering a new class of drugs called ImmTACs, they were able to show that ImmTAC could, potentially, result in the regression of established […]

Entropy and Particle Shape Cause Chirality in Dense Systems

Achiral triangles form chiral super-structures

To better understand why functional molecules in our bodies almost always occur in just one chiral form, UCLA scientists sought to discover how chirality occurs. By using lithography to create microscale particles, the researchers found that entropy and particle shape are enough to cause chirality to appear spontaneously in dense systems. The overwhelming majority of […]

Revealing Data from Super-Earth 55 Cancri e

light from a super-Earth

Sitting 40 million light-years away, researchers were able to gain a better understand of 55 Cancri e and its environment. Using observations from NASA’s Spitzer Space Telescope, the team found that its temperature is roughly 2,360 degrees Kelvin and that 55 Cancri e orbits its star much like the moon circles Earth. Scientists on a […]

Can Jupiter-Like Planets Lead to Earth-Like Planets?

Jupiter and its four planet-size moons

Scientists are searching for Earth-like planets by searching near Jupiter-like planets. Using data from NASA’s Kepler mission, scientists have identified 63 candidate hot Jupiter systems, but currently have not found any evidence for nearby companion planets. Washington, D.C.— In the search for Earth-like planets, it is helpful to look for clues and patterns that can […]

Nanoparticle Probes to Uncover the Secrets of Proteins

nanoparticle probes that may lead to a better understanding of diseases

(Video:Andrew Mueller, Vistamar School, El Segundo, Calif.) Studying and understanding protein behavior is about to take a major step forward. Scientists from the Berkley Lab have figured out how to grow light-emitting nanocrystals small enough not to disrupt cell activity but bright enough to be imaged one at a time, resulting in nanoparticle probes that […]

Pentamode Metamaterial Opens New Possibilities in Transformation Acoustics

stable four-leg structure is the basic element of the pentamode metamaterial

A team of scientists have created new material class through the manufacturing of a stable crystalline metafluid. The pentamode metamaterial is extremely light and displays mechanical behavior that is determined by the acuteness and length of the individual “sugar loaves.” A research team lead by Professor Martin Wegener at the Karlsruhe Institute of Technology (KIT) […]

Earth’s Water Supply Summed Up in One “Tiny” Bubble

Picture of Earth showing if all Earth's water

You’ve probably heard the saying that Earth is mostly water, roughly 70%. Well it turns out that many people have misunderstood the facts and that it’s only the Earth’s surface that is mainly water. To get a better understanding of the limited amount of water on Earth, the USGS gives a visual explanation with one […]
