April 3 - Today in Science History - Scientists born on April 3rd, died, and events - 0 views

  • First cell phone call
  • In 1973, the first portable phone call was placed by inventor Martin Cooper. The phone was 10 inches in height, 3 inches deep and an inch-and-a-half wide and weighed 30-oz. Since then, cell phones have shrunk to a mere palm-size weighing 4-oz, and are used by a billion people around the world. Cooper's first ''shoebox'' phone replaced a car phone of the time that weighed more than 30 pounds and cost thousands of dollars. A car phone owner had to drill a hole in his car to install the antenna and most of the phone sat in the trunk. A control unit with a handset was placed inside the car

ScienceShot: There's Cow in Your Smog - ScienceNOW - 0 views

  • people typically blame Southern California's smog on automobiles, a new study suggests that cows may be just as responsible, if not more so
  • large fraction of the region's smog, especially the particles smaller than 2.5 micrometers in diameter, is ammonium nitrate
  • particles form in the atmosphere when ammonia, which is generated by cars with certain types of catalytic converters and by bacteria that consume cattle waste, reacts with nitrogen oxides that are produced in large quantities in automobile emissions
  • ...3 more annotations...
  • Data gathered during low-altitude flights in and around the Los Angeles basin in May 2010 suggest that the region's 9.9 million autos generate about 62 metric tons of ammonia each day
  • ammonia emissions from dairy farms in the eastern portion of the basin—home to about 298,000 cattle—range between 33 and 176 metric tons per day
  • Ammonia emissions from the dairy farms are concentrated, boosting atmospheric levels of the gas to more than 100 times background levels, so efforts to curb the farms' emissions (perhaps by feeding the animals different diets) might reduce smog more than those targeting cars.

  • Glenn in orbit
  • In 1962, John Glenn piloted the Mercury-Atlas 6 Friendship 7 spacecraft on the first U.S. manned orbital mission. Launched from Kennedy Space Center, Florida, he completed three-orbits around the earth, at a maximum altitude of approx. 162 miles and an orbital velocity of approx. 17,500 mph. He spotted Perth, Australia, when that city's residents greeted him by switching on their house lights in unison. A four-cent U.S. stamp was put on sale the same day, making it the first U.S. stamp issued on the day of the event it commemorated. Glenn returned to space 36 years later, making 134 more orbits as a crew member of the space shuttle Discovery (29 Oct - 7 Nov 1998) for investigations on space flight and the aging process.
  • In 1986, the Soviet Union launched into orbit Mir, a new space station. Mir, the Russian word for peace, had six docking ports and special laboratories for scientific research. Weeks later, a veteran crew was sent to man the 56-ft-long and 13.6-ft wide station. The core module provided living quarters for the cosmonauts: galley/table, cooking elements and storage, individual crew cabins and personal hygiene area. They also had a working compartment for monitoring and commanding the core systems supported by an electric power system, thermal control system, computer systems, environmental control and life support, communications and tracking systems. Five additional modules were launched between Mar 1987 and April 1996

Designed by aeroengineer Waldo Dean Waterman (1894-1976), it evolved from the prototype Arrowplane, a project to design a simple, easy to fly, low cost airplane. The Studebaker Corporation, which supplied the 100 hp engines, eventually took delivery of five Arrowbiles

Cholesterol-lowering eye drops could treat macular degeneration - 0 views

  • A new study raises the intriguing possibility that drugs prescribed to lower cholesterol may be effective against macular degeneration, a blinding eye disease.
  • Researchers
  • have found that age-related macular degeneration, the leading cause of vision loss in Americans over 50, shares a common link with atherosclerosis
  • ...25 more annotations...
  • Both problems have the same underlying defect: the inability to remove a buildup of fat and cholesterol
  • researchers shed new light on how deposits of cholesterol contribute to macular degeneration and atherosclerosis and even blood vessel growth in some types of cancer
  • Patients who have atherosclerosis often are prescribed medications to lower cholesterol and keep arteries clear
  • This study suggests that some of those same drugs could be evaluated in patients with macular degeneration
  • we need to investigate whether vision loss caused by macular degeneration could be prevented with cholesterol-lowering eye drops or other medications that might prevent the buildup of lipids beneath the retina
  • The new research centers on macrophages, key immune cells that remove cholesterol and fats from tissues
  • In macular degeneration, the excessive buildup of cholesterol begins to occur as we age, and our macrophages begin to malfunction
  • In the "dry" form of age-related macular degeneration, doctors examining the eye can see lipid deposits beneath the retina
  • As those deposits become larger and more numerous, they slowly begin to destroy the central part of the eye, interfering with the vision needed to read a book or drive a car
  • As aging macrophages clear fewer fat deposits beneath the retina, the macrophage cells themselves can become bloated with cholesterol, creating an inflammatory process that leads to the formation of new blood vessels that can cause further damage
  • Those vessels characterize the later "wet" form of the disease
  • that inflammation creates a toxic mix of things that leads to new blood vessel growth
  • Most of the vision loss
  • is the result of bleeding and scar-tissue formation related to abnormal vessel growth
  • the scientists identified a protein that macrophages need to clear fats and cholesterol
  • As mice and humans age, they make less of the protein, and macrophages become less effective at engulfing and removing fat and cholesterol
  • team found that macrophages, from old mice and in patients with macular degeneration, have inadequate levels of the protein, called ABCA1, which transports cholesterol out of cells
  • As a result, the old macrophages accumulated high levels of cholesterol and couldn't inhibit the growth of the damaging blood vessels
  • when the researchers treated the macrophages with a substance that helped restore levels of ABCA1, the cells could remove cholesterol more effectively, and the development of new blood vessels was slowed
  • able to deliver the drug, called an LXR agonist, in eye drops
  • found that we could reverse the macular degeneration in the eye of an old mouse
  • could focus therapy only on the eyes, and we likely could limit the side effects of drugs taken orally
  • since macrophages are important in atherosclerosis and in the formation of new blood vessels around certain types of cancerous tumors, the same pathway also might provide a target for more effective therapies for those diseases
  • can reverse the disease cascade in mice by improving macrophage function, either with eye drops or with systemic treatments,
  • Some of the therapies already being used to treat atherosclerosis target this same pathway, so we may be able to modify drugs that already are available and use them to deliver treatment to the eye
