Take a virtual trip inside the human body at a cellular level to see how blood vessels grow to feed tumors. Stopping this growth is one of the primary lines of attack scientists take in trying to defeat diseases, cancer in particular.
Electronics made of graphene--sheets of carbon just an atom thick--could be considerably faster than those made of silicon.
Astute observations led a team of clinicians and researchers to uncover how this drug can also boost our bodies' bone stem cell production to the point that adults' bones appear to have the ability to heal at a rate typically seen when they w
A fierce battle between Roman defenders and invading Persians took place at Dura, a garrison city on the Euphrates River in what is now Syria. That was around a.d. 256, nearly seventeen centuries before the 1925 Geneva Protocol outlawed the use of po
Our teeth are put to the test every day, withstanding all the crunching and munching of meals and snacks. This remarkable resilience appears to be due to the microscopic "basket-weave" structure of human tooth enamel, a new study finds.
Contrary to what was known, all octopuses are venomous, a new study finds. Researchers knew that the blue-ringed octopus packed venom. Now they say all octopuses and cuttlefish, and some squid are venomous.
Patients recently diagnosed with type 1diabetes who received transplants of their own immune stem cells were able to go without insulin injections for nearly five years after the procedure, scientists report today.
A North Carolina man who was rendered sterile by cancer treatment as a teenager is now a father after doctors used a sperm sample he donated 22 years ago to impregnate his wife.
Jamie and Adam are not satisfied with the two semis not pancaking a compact and fusing together...so they go to New Mexico to get a rocket to smash into a car at 650 mph...watch the car pretty much erase. [oh, yes, boys and their toys]
Scientists have produced strong new evidence challenging one of the most fundamental assumptions in biology: that female mammals, including women, are born with all the eggs they will ever have.
Archaeologists working in an Egyptian oasis have found a necropolis containing dozens of brightly painted mummies dating back as far as 4,000 years. "The mission found dozens of mummies in 53 rock-hewn tombs dating to the Middle Kingdom"
We might not see anything," he continues, "but if we discover lots of asteroids around L4 or L5, it could lead to a mission to analyze the composition of these asteroids in detail. If that mission discovers the asteroids have the same compo
Places like Nigeria, Congo, Angola, Gabon, and Cameroon have similar reports of huge, long-necked monsters, some with a length of 75 feet! Native sightings have been confirmed by reports from missionaries, explorers, and even army personnel. The nati
The device works much the same as a traditional generator, except that fast-acting electronic switches can engage individual generator coils as needed to harvest energy effectively at different wind speeds. An intelligent controller turns
But Holdren noted that shooting particles into the air — making an artificial volcano as one Nobel laureate has suggested — could have grave side effects and would not completely solve all the problems from soaring greenhouse gas emissions.
The viruses, in effect, pull the needed compounds (gold and cobalt for the anode and iron phosphate and carbon for the cathode) into nanowires. Both the cathode and the anode for the battery were constructed by viruses, though the battery created is
During this work, the team demonstrated a new mode of bond generation between oxygen atoms and even defined the mechanism by which it takes place. In fact, it is the generation of oxygen gas by the formation of a bond between two oxygen atoms ori
Experts have pinpointed the part of the brain that guides people when they are battling with difficult moral dilemmas. Sophisticated brain scans show the response is linked to areas associated with primitive emotions of sex, fear and anger.
In a breakthrough for applied physics, North Carolina State University researchers have developed a magnetic semiconductor memory device, using GaMnN thin films, which utilizes both the charge and spin of electrons at room temperature.
A better method of making fuel from algal oil has got a lot of biofuel analysts excited: "This is the first economical way to produce biodiesel from algae oil," according to lead researcher Ben Wen, Ph.D., vice president of United Environme
Suppose scientists could erase certain memories by tinkering with a single substance in the brain. Could make you forget a chronic fear, a traumatic loss, even a bad habit. Researchers in Brooklyn have recently accomplished comparable feats
A drug given to kleptomaniacs took some of the fun out of stealing. "It gets rid of that rush and desire," said a study team member. "The difference in their behavior was significant, and these people were really troubled by their beha
When dark matter is destroyed, it leaves behind a burst of exotic particles, according to theory. Now scientists have found a possible signature of these remains. The discovery could help prove the existence of dark matter and reveal what it's ma
The alloy the team has found—a mixture of manganese, iron, phosphorus and germanium—is not merely the first near-room-temperature magnetocaloric to contain neither gadolinium nor arsenic—rendering it both safer and cheaper—but also it has such strong
The threat is worse than described. All our electrical devices will be fried. The internet disappears and all our household devices likely catch fire. They have wonderful coils to overload. All the replacement parts are also fried in our warehouses.
That cup of coffee that many gym rats, bikers and runners swill before a workout does more than energize them. It kills some of the pain of athletic exertion, a new study suggests. And it works regardless of whether a person already had a coffee habi
Twenty years from now, large rotorcraft could be making short hops between cities such as New York and Washington, carrying as many as 100 passengers at a time in comfort and safety. Routine transportation by rotorcraft could help ease air traffi
stronger than steel, as stretchy as rubber, and as light as air. The ribbons, which are made of long, entangled 11-nanometer-thick nanotubes, can stretch to more than three times their normal width but are stiffer and stronger than steel or Mylar len
An international team of scientists in Europe has created a silicon chip designed to function like a human brain. With 200,000 neurons linked up by 50 million synaptic connections, the chip is able to mimic the brain's ability to learn more close
The tissue creates a scaffold for nerve tissue regeneration.
