Mechanism for Controlling Calcium Influx in Cells Identified

Mechanism for Controlling Calcium Influx in Cells Identified

In a newly published study, scientists identify the mechanism for controlling calcium influx in cells, helping researchers better understand the molecular causes of the disruption of brain functioning that occurs in stroke and other neurological disorders. When brain cells are overwhelmed by an influx of too many calcium molecules, they shut down the channels through […]

Thermal Cloak Molds the Flow of Heat Around an Object

Invisibility Cloak for Thermal Flow

Scientists from the Karlsruhe Institute of Technology have constructed a micro-structured thermal cloak that molds the flow of heat around an object. By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of […]

Study Suggests Europeans Are Closely Related

Geography of Recent Genetic Ancestry Across Europe

A newly published study suggests that Europeans are closely related, finding on a genealogical level that everyone in Europe traces back to nearly the same set of ancestors only a thousand years ago. From Ireland to the Balkans, Europeans are basically one big family, closely related to one another for the past thousand years, according […]

New Climate Model Suggests Boreal Forests to Shift North and Relinquish More Carbon Than Expected

As Climate Changes Boreal Forests to Shift North

New climate change research from the Berkeley Lab suggests that boreal forests will likely shift north and will relinquish more trapped carbon than most current climate models predict. It’s difficult to imagine how a degree or two of warming will affect a location. Will it rain less? What will happen to the area’s vegetation? New […]

Potential New Therapy Stops Tumor Growth

Monoclonal Antibody Therapy Stops Tumor Growth in Mice

Scientists have identified a way to flip a genetic switch off to halt tumor growth, demonstrating a potential new therapy in mice that impacts tumor growth in a significant way. Approximately 90 percent of cancers start within tissues that form the inner linings of various organs. Decades of accumulated genetic mutations can, on occasion, induce […]

Researchers Believe They Can Reliably Predict Snowstorms on Mars

Climate Model Helps Predict Snowstorms on Mars

Using a climate model adapted to the special conditions on Mars, researchers believe they can reliably predict snowstorms on Mars far in advance, helping future missions choose better routes that avoid heavy snowfall. Snowstorms lashing down at the northern hemisphere of Mars during the icy cold winters may be predicted several weeks in advance, say […]

Increased Parkin Gene Levels Can Delay the Aging Process

Boositng Parkin Gene Can Delay Aging

In a new study, UCLA researchers increased parkin levels in the cells of fruit flies, discovering that this extended their life span by more than 25 percent as compared with a control group that did not receive additional parkin. UCLA life scientists have identified a gene previously implicated in Parkinson’s disease that can delay the […]

New Metamaterial Doubles the Range of Light that Can Be Manipulated

Stanford Scientists Designing a Metamaterial that Doubles the Range of Light that Can Be Manipulated

By designing a broadband metamaterial that more than doubles the range of wavelengths of light that can be manipulated, Stanford scientists have taken an important step toward designing a metamaterial that works across the entire visible spectrum. All natural materials have a positive index of refraction – the degree to which they refract light. The […]

Scientists Reveal a New Species of Dinosaur

Scientists Reveal a New Species of Dinosaur

New research describes the newly discovered species of bone-headed dinosaur, named Acrotholus audeti, which lived about 85 million years ago. Scientists have named a new species of bone-headed dinosaur (pachycephalosaur) from Alberta, Canada. Acrotholus audeti (Ack-RHO-tho-LUS) was identified from both recently discovered and historically collected fossils. Approximately six feet long and weighing about 40 kgs […]

New Study Suggests Wind, Not Water, Formed Mount Sharp on Mars

New Study Suggests Wind Not Water Formed Mount Sharp

In a newly published study, scientists from Princeton University and the California Institute of Technology suggest that Mount Sharp most likely emerged as strong winds carried dust and sand into the 96-mile-wide crater in which the mound sits. A roughly 3.5-mile high Martian mound that scientists suspect preserves evidence of a massive lake might actually […]

A New Kind of Cosmic Flash May Reveal the Birth of a Black Hole

The Birth of a Black Hole

According to a newly published study from Caltech astrophysicist Anthony Piro, a new kind of cosmic flash may reveal the birth of a black hole. When a massive star exhausts its fuel, it collapses under its own gravity and produces a black hole, an object so dense that not even light can escape its gravitational […]
