Searching for an Efficient Way to Make Methanol

atoms on the surface of an industrial catalyst used in methanol production

Researchers from SLAC and Stanford have teamed with scientists at the Max Planck Institute to examine catalysts in an effort to find an efficient way to make methanol from the carbon dioxide that’s produced by burning fossil fuels, turning a global warming source into a global warming solution. What’s the best way to make methanol? […]

Cancer Cells May Grow More Easily than Thought

cancer cells may grow more easily

Geneticists at Harvard Medical School have discovered how a deletion in one gene from one parent, called a “hemizygous” deletion, can contribute to cancer, suggesting that cancer cells may grow more easily than researchers had hoped. Chromosomal deletions in DNA often involve just one of two gene copies inherited from either parent. But scientists haven’t […]

Evolution Shapes Ecology of Dammed Connecticut Lakes

Zooplankton (bosminia)

In a newly published study, Yale biologists describe how dams built 300 years ago in Colonial times fundamentally changed the structure of the alewife, the water flea that the alewife feeds upon and the food chain that supports them both. Environmental change is the selective force that preserves adaptive traits in organisms and is a […]

Physicists Realize New Quasiparticle in Ultracold Quantum Gas

Quasiparticles Realized

Physicists at the University of Innsbruck have succeeded for the first time in experimentally realizing a new quasiparticle, a repulsive polaron, in an ultracold quantum gas consisting of lithium and potassium atoms in a vacuum chamber. Ultracold quantum gases are an ideal experimental model system to simulate physical phenomena in condensed matter. In these gases, […]

Circumpolar Rivers are a Major Source of Mercury in the Arctic Ocean

study finds circumpolar rivers source of mercury in the Arctic

A new study from environmental scientists suggests that the mercury concentration in the Arctic Ocean is being fueled by both an atmospheric source, which was previously recognized, and by the flow of circumpolar rivers. Environmental scientists at Harvard have discovered that the Arctic accumulation of mercury, a toxic element, is caused both by atmospheric forces […]

Researchers Identify BAD as Key Seizure-Suppressing Protein

protein that plays a key role in suppressing epileptic seizures

New research from the Harvard Medical School and the Dana-Farber Cancer Institute examines why a diet high in fat and low in carbohydrates can reduce epileptic seizures. In mice, researchers used modified BAD protein to reduce glucose metabolism and increase ketone body metabolism in the brain, decreasing seizures and making BAD a promising target for […]

Leaf Vein Architecture Allows Predictions of Past Climate

leaf vein architecture allows predictions of past climate

A newly published report describes the mathematical linkages between leaf vein systems and leaf size from around the globe, improving scientists’ ability to predict and interpret climate of the deep past from leaf fossils. UCLA life scientists have discovered new laws that determine the construction of leaf vein systems as leaves grow and evolve. These […]

Crowding Causes Internal Cell Structure Alignment

alignment of the protein networks outside the cell

By mimicking the crowded environment in actual cells, a team of researchers found that certain molecules organize as they would in the body, inducing a dramatic alignment of the protein networks outside the cell and causing the cell to align its internal structure. When researchers conduct experiments on the way cells grow and respond to […]

Needleless Device Jet-Injects Drugs at the Speed of Sound

MIT-engineered device injects drug without needles

By using a design that incorporates a small, powerful magnet surrounded by a coil of wire that’s attached to a piston inside a drug ampoule, engineers have developed a device that delivers a tiny, high-pressure jet of medicine through the skin without the use of a hypodermic needle. Getting a shot at the doctor’s office […]

Calculations Show the Ideal Time to Study the Cosmos

ideal time to study the cosmos was more than 13 billion years ago

The time to study the cosmos is now. New calculations show that the expansion of the cosmos is accelerating, galaxies are being pushed beyond our horizon and the scale of gravitationally unbound structures is growing larger and will eventually stretch beyond our horizon as well. Cambridge, Massachusetts – The universe is a marvelously complex place, […]

Physical Properties of Stem Cells Predict What They Will Become

Physical properties predict stem cell use

New research from Brown University shows that the physical properties of adult stem cells derived from fat, such as liposuction waste, can predict whether they will turn into bone, cartilage, or fat, leading to a potential method of concentrating them for use in specialized healing. Providence, Rhode Island (Brown University) — To become better healers, […]

Oxygen Depletion and Acidification Accelerate Coral Death

coral death by a deadly chain reaction

To better understand how to protect coral reefs, a team of microbiologists are investigating how environmental changes, such as oxygen depletion and ocean acidification, create a chain reaction that leads to coral death. Most people are fascinated by the colorful and exotic coral reefs, which form habitats with probably the largest biodiversity. But human civilization […]
