One day, patients may be able to monitor their body's response to cancer therapy just by having their blood drawn. A new study has taken an important step in that direction by measuring a panel of cancer proteins in rare, individual tumor cells that float in the blood.
Moderate drinking is associated with a lower risk of several, but not all, cardiovascular diseases, finds a large study of UK adults. The finding that moderate drinking is not universally associated with a lower risk of all cardiovascular conditions suggests a more nuanced approach to the role of alcohol in prevention of cardiovascular disease is necessary.
Astronomers have uncovered a monster black hole that has been propelled out of the center of a distant galaxy, called 3C 186, by what could be the power of gravitational waves. A paper describing the discovery will appear in the March 30, 2017 issue of the journal Astronomy & Astrophysics (arXiv.org preprint). Though several other [...]
As wolf populations plummeted, the eastern coyote assumed the role of apex predator in forests along the Atlantic Coast. New research, however, shows that the eastern coyote is no match for the wolf. While the eastern coyote can bring down moose and other large prey, it prefers to attack smaller animals and to scavenge.
Through experimental and computational tests, new research expands on the theory of virus surface hydrophobicity. By being slightly water-repellent, the outer layers of proteins in virus capsids affect how it interacts with cells and the environment. Understanding this more can improve vaccine production and virus detection.
Scientists have developed a new method that can be used to construct custom hybrid structures using DNA and proteins. The method opens new opportunities for fundamental research in cell biology and for applications in biotechnology and medicine.
On the eve of this year's Earth hour (March 25), researchers propose a solution in the journal Science for the global economy to rapidly reduce carbon emissions. The authors argue a carbon roadmap, driven by a simple rule of thumb or 'carbon law' of halving emissions every decade, could catalyze disruptive innovation.
Scientists report data from a new study providing evidence that random, unpredictable DNA copying 'mistakes' account for nearly two-thirds of the mutations that cause cancer. Their research is grounded on a novel mathematical model based on DNA sequencing and epidemiologic data from around the world.
Astronomers have directly observed a pair of Milky Way-like galaxies seen when the universe was only eight percent of its current age. These progenitors of today's giant spiral galaxies are surrounded by 'super halos' of hydrogen gas that extend many tens-of-thousands of light-years beyond their dusty, star-filled disks.
Results from experiments and computational modeling studies that definitively identify the 'active site' of a catalyst commonly used for making methanol from CO2 will guide the design of improved catalysts for transforming this pollutant to useful chemicals.
It is well known that as plants grow, their stems and shoots respond to outside signals like light and gravity. But if plants all have similar stimuli, why are there so many different plant shapes? Using simple mathematical ideas, researchers have constructed a framework that explains and quantifies the different shapes of plant stems.
Carbapenems are among the 'antibiotics of last resort' and can fight infections for which other drugs have long lost their effectiveness. However, even carbapenem-resistant pathogenic strains have emerged over the last decades.
A special kind of small sulfur-rich proteins, the metallothioneins, have an extraordinarily large capability for binding heavy metals. An international team of scientists has now discovered that the marine common periwinkle, which is widely considered a delicacy, contains the largest version of the protein found yet, with one additional cadmium-binding domain and a one-third higher detoxification capacity. This feature may help the snail survive in heavy-metal-polluted environments.
Astronomers have identified a record breaking brown dwarf (a star too small for nuclear fusion) with the 'purest' composition and the highest mass yet known. The object, known as SDSS J0104+1535, is a member of the so-called halo -- the outermost reaches -- of our galaxy, made up of the most ancient stars.
Exoplanet hunters struck gold earlier this year with the discovery of seven rocky bodies orbiting around dwarf star TRAPPIST-1, a find that both raised hopes, and provided a new target, for understanding if life exists elsewhere in the cosmos. Now, new calculations from Harvard researchers suggest this populous planetary system could also help us understand [...]
