In recent years, scientists have discovered that a family of enzymes called sirtuins can dramatically extend life in organisms as diverse as yeast, worms, and flies. They may also be able to control…

According to a recent paper published by MBARI geologists and their colleagues, methane gas bubbling through seafloor sediments has created hundreds of low hills on the floor of the Arctic Ocean.…

Cancer cells are sick, but they keep growing because they don't react to internal signals urging them to die. Now researchers at Washington University School of Medicine in St. Louis have found an…

Nanotechnology is one of the ‘next big things’ in our future.  People have elevated it to a level of near worship as the way to solve, and in some cases revolutionize a number of areas of human…

Physicists at JILA have demonstrated that the warmer a surface is, the stronger its subtle ability to attract nearby atoms, a finding that could affect the design of devices that rely on small-scale…

For women older than 35, amniocentesis is usually recommended. But the Society of Obstetricians and Gynaecologists of Canada (SOGC) is now presenting a new guideline system: All women should have…

Two biologists at Penn State have discovered a master regulator that controls metabolic responses to a deficiency of essential amino acids in the diet. They also discovered that this regulatory…

Physicists have for the first time stopped and extinguished a light pulse in one part of space and then revived it in a completely separate location. They accomplished this feat by completely…

A study at UCL (University College London) finds that a high-prevalence of male-killing bacteria active in many species of insect including the butterfly, actually increases female promiscuity and…

The largest climate change in central North America since the age of the dinosaurs 65 million years ago, a temperature drop of nearly 15 degrees Fahrenheit, is documented within the fossilized teeth…

New research findings may help refine the accepted models used by earth scientists over the past 30 years to describe the ways in which continents clash to form the Earth's landscape. Eric Calais, an…

A new analysis led by an MIT scientist describes a mechanism for capturing carbon dioxide emissions from a power plant and injecting the gas into the ground, where it would be trapped naturally as…

Pity the molecular biologist. The object of fascination for most is the DNA molecule. But in solution, DNA, the genetic material that hold the detailed instructions for virtually all life, is a…

"What is a supermodel?" People sometimes ask me. It has a few definitions and sometimes people argue over them, much the way Heidi Klum and Elle MacPherson fight over who is called "The Body." * But…

At last, neuroscience is having an impact on computer science and artificial intelligence (AI). For the first time, scientists in Tomaso Poggio’s laboratory at the McGovern Institute for Brain…

A first-of-its-kind study published in the February issue of the Journal of Neurosurgery: Pediatrics suggests endoscopic brain surgery, pioneered by surgeons at the University of Pittsburgh Medical…

The simultaneous effect of habitat fragmentation, overexploitation, and climate warming could accelerate the decline of populations and substantially increase their risk of extinction, a study…

A new computer-based technique could eliminate hours of manual adjustment associated with a popular cancer treatment. In a paper published in the Feb. 7 issue of Physics in Medicine and Biology,…

We may not be as fit as the people of ancient Athens, despite all that modern diet and training can provide, according to research by University of Leeds exercise physiologist, Dr Harry Rossiter. Dr…

Astronomers from the University of Virginia and other institutions have found that Enceladus, the sixth-largest moon of Saturn, is a “cosmic graffiti artist,” pelting the surfaces of at least 11…
