New Pill To Stop Strokes -- Express.co.uk

A PILL costing less than £3 a day is being hailed as the biggest breakthrough in stroke prevention in 50 years.

The drug, which slashes the risk of suffering a stroke by over a third, will help more than a million Britons.

Pradaxa is now available for use in the UK. In trials it was found to significantly reduce the risk of a stroke in patients with an irregular heartbeat, known as atrial fibrillation. This is one of the main causes of strokes.

The Impact Of High-Density Reactive Materials (HDRM)

High-Density Reactive Material (HDRM) missiles increase the chances of a "catastrophic kill," according to US military scientists.

US Military Develops 'Bigger Bang' Explosive Material -- BBC

The US Office of Naval Research says that it has successfully tested a new type of explosive material that can dramatically increase weapons' impacts.

Missiles made from the high density substance can explode with up to five times the energy of existing armaments.

The material mixes metals and polymers and is said to be as dense as steel but have the strength of aluminum.

New NASA Moon Rocket Could Cost $38 Billion -- L.A. Times

At that price tag, it would fly just twice in the next 10 years, according to internal NASA documents. That could pose big problems for NASA supporters in Congress.

Reporting from Washington — The rocket and capsule that NASA is proposing to return astronauts to the moon would fly just twice in the next 10 years and cost as much as $38 billion, according to internal NASA documents obtained by the Orlando Sentinel.

The money would pay for a new heavy-lift rocket and Apollo-like crew capsule that eventually could take astronauts to the moon and beyond. But it would not be enough to pay for a lunar landing or for more than one manned test flight, in 2021.

Possibility of Temporarily Reversing Aging in the Immune System -- Science Daily

ScienceDaily (Aug. 16, 2011) — Researchers have discovered a new mechanism controlling aging in white blood cells. The research, published in the September issue of the Journal of Immunology, opens up the possibility of temporarily reversing the effects of aging on immunity and could, in the future, allow for the short-term boosting of the immune systems of older people.

Weakened immunity is a serious issue for older people. Because our immune systems become less effective as we age we suffer from more infections and these are often more severe. This takes a serious toll on health and quality of life.

Melting Glaciers Alter Earth's Gravity -- Live Science

Melting glaciers can alter Earth's gravity field, scientists have found, a discovery that is shedding light on when Greenland and Antarctica began heavily melting.

Knowing the timing of this melting could help climate scientists make better estimates of the potential sea level rise resulting from melting ice pouring off these two massive ice sheets.

My comment: There is no details on how much of a shift in gravity has occurred. My suggestion .... compile the data between summer and winter, and look at the difference.

A One-Armed Personal Robot For The Rest Of Us

PR2 SE Half the arms, nearly half the price. Willow Garage

Willow Garage Introduces Discount PR2 SE, a One-Armed Personal Robot for the Rest of Us -- Popular Science

Willow Garage’s PR2 has provided a unique, open source robotics platform to all kinds of labs and institutions that otherwise wouldn’t have access to a complex robotics system--but not to that many. For all the absolutely cool things you can do with PR2, the $400,000 price tag is prohibitive--only about two dozen commercial and academic labs have their own PR2s. So, in an attempt to make their robot more accessible, Willow Garage is introducing the PR2 SE this week, a pared-down version of the same robot costing a mere $285,000.

Anti-Wave Tech Tricks Ocean Water Into Standing Still, Making Ships Efficient and Invisible -- Popular Science

We’ve already seen how future ships can be cloaked against sonar, and maybe someday even space and time. Now researchers say they can cloak the ships’ wakes, tricking water itself into acting as though nothing is there.

A new metamaterial cloaking system can trick water into standing still as an object moves through it, by eliminating the shear force and reducing water displacement, Duke University researchers say. This in turn reduces the amount of energy required to move an object — say, a ship — through the water, theoretically saving fuel.

My Comment: And this is the research that they are publicizing .... I would love to know what they are not telling us.

Military's Maple-Seed-Inspired Drone

Sneak Preview: Military's Maple-Seed-Inspired Drone, Plus More to Come at UAV Show Next Week -- Popular Science

After years of development and military funding setbacks, defense contractor Lockheed Martin is finally ready to debut its maple seed-inspired drone. The one-winged, one-foot-long SAMARAI drone just flew a test flight for the Associated Press ahead of its official unveiling at an unmanned vehicle conference next week.

The asymmetric UAV is modeled after maple seeds, called samara, that fly off trees and twirl through the air with the utmost efficiency. Originally, the SAMARAI was envisioned as a seed-sized drone that could deliver a 2-gram payload and send back streaming video, but that has since changed to a much bigger, whining drone.

My Comment: It appears that the future for UAVs is to be miniaturized .... the smaller the better.

SETI Project Is Back Online

SETI Project: We're Listening Again, ET -- Mercury News

E.T., you can phone home again.

Forty-two radio telescope dishes near Mount Shasta will again start listening for sounds of intelligent life in the universe this fall after donors -- including actress Jodie Foster -- came up with more than $200,000 to save the Mountain View-based SETI program, made famous by the movie "Contact."

The Allen Telescope Array was shut down in April when the SETI (Search of Extraterrestrial Intelligence) Institute ran short of of money for the project.

The Blackest Planet: Astronomers Uncover Alien World So 'Extraordinarily Dark' It Makes Coal Look Shiny -- Daily Mail

Astronomers have discovered the darkest known planet.

The exoplanet, known as TrES-2b, reflects less than 1 per cent of light, which makes it darker than any other planet or moon.

The discovery, detailed in the journal Monthly Notices of the Royal Astronomical Society, was made by analysing data from Nasa's Kepler spacecraft, which provides extremely precise measurements on the brightnesses of faraway stars.

Jodie Foster Helps Revive SETI Search For Aliens -- Live Science

E.T., the phone line is open and SETI is waiting for your call. And apparently Jodie Foster, too.

The nonprofit Search for Extraterrestrial Intelligence (SETI) Institute, which was forced earlier this year to shutter its Allen Telescope Array, used to listen for alien signals, due to budget issues, has raised enough money to resume the search for life beyond planet Earth.

The institute reached its goal last week of raising $200,000 to operate the telescope through the end of this year. The funds came from over 2,000 private donors, including the actress Jodie Foster, who played fictional SETI scientist Ellie Arroway in the 1997 movie "Contact."

U.S. Science Funding Will Soon Be Cut Because Of The Debt Deal

U.S. Debt Deal Could Dramatically Slash Science Funding In 2013 -- Scientific American

US science agencies avoid immediate pain but could be devastated by automatic cuts in 2013.

Scalpel or guillotine? Those are the possible fates in store for US science funding after Congress and the White House reached a deal to cut federal spending and raise the nation's self-imposed debt limit before a 2 August deadline.

The product of tumultuous negotiations, the deal largely spares science in the short term but puts a day of reckoning on the horizon: 2 January 2013. If politicians cannot agree on how to improve the government's fiscal outlook by then through targeted cuts and other means--the scalpel option--their failure will automatically trigger the guillotine: a deep cut applied across a range of expenditures, including research. In the worst case, the automatic cuts could mean shuttered laboratories and mass lay-offs at universities.

My Comment: The cutting has already happened .... look at NASA

Mars Rover Nears End Of Road

Eight Years And 34 Million Miles On, Mars Rover Nears End Of Road -- The Independent

It travelled at an average speed of 60cm an hour and it has arrived a year late. But the Mars rover Opportunity is finally approaching its destination, the rim of the vast Endeavour crater.

Nasa hailed the six-wheel Opportunity's approach to the 22.5km-wide crater last night as a "tremendous scientific success".

The ageing robotic field geologist has logged more than 32km since it was first parachuted on to the planet's surface in 2003, along with its twin rover Spirit, for a planned three-month mission after their 34 million-mile journey from Earth. Spirit emitted its last signal a year ago after becoming trapped in sand. Opportunity crawled out from a crater in 2008 and headed south to the Endeavour, a two-year journey in theory, which has taken longer because Opportunity had to drive backwards to prevent its front wheel from wearing out.

Sun Unleashes Largest Solar Flare In Five Years

Sun Unleashes Largest Solar Flare In Five Years, Sending 10Billion Ton Storm Cloud Hurtling Through Space At 5Million MPH -- Daily Mail

The sun unleashed an unusually powerful solar flare yesterday, the largest in nearly five years.

The eruption launched a ten billion ton storm cloud hurtling through space at five million miles per hour.

Scientists said the event took place on the side of the sun that was not facing Earth, so there will be little impact to satellites and communication systems.

Antimatter Belt Around Earth Discovered By Pamela Craft -- BBC

A thin band of antimatter particles called antiprotons enveloping the Earth has been spotted for the first time.

The find, described in Astrophysical Journal Letters, confirms theoretical work that predicted the Earth's magnetic field could trap antimatter.

The team says a small number of antiprotons lie between the Van Allen belts of trapped "normal" matter.

The researchers say there may be enough to implement a scheme using antimatter to fuel future spacecraft.

Working In An Office Is Bad For Your Brain -- The Telegraph

Working in an office is bad for your brain and can make you less productive, according to researchers.

A study has found that the hustle and bustle of modern offices can lead to a 32% drop in workers well being and reduce their productivity by 15%.

They have found that open plan offices create unwanted activity in the brains of workers that can get in the way of them doing the task at hand.

Open plan offices were first introduced in the 1950s and quickly became a popular as a way of laying out offices.

Having a clean and sterile desk can also leave employees with smaller brains, scientists claim.

Is Music A Powerful Antidepressant?

Making Music Proves To Be Powerful Antidepressant -- Live Science

Making music might help lift more depressed people out of the dumps than common antidepressant medications do, the results of a new study suggest.

That's not to say the people with depression should toss out their meds and pick up a guitar. The music therapy administered to patients in the new study was in addition to regular therapy, and the patients continued their regular medication routines. But about one out of four depression sufferers is likely to respond to music therapy, Finnish researchers reported in August in the British Journal of Psychiatry. In comparison, a 2009 review of research published in the journal Cochrane Database Systemic Review found that doctors must treat between seven and 16 people with tricyclic antidepressant drugs for one person to see improvement.
