Poisonous snakes need not look big and scary. In fact, the Namaqua dwarf adder, Bitis schneideri,
is the world’s shortest venomous snake. Found in southern Africa, this
sidewinder grows to an average length of 18-24cm, the length of a small
ruler! Typically, the Namaqua lives in desert habitats. Although its
venom is poisonous, the Namaqua rarely bites humans and has never been
reported as the cause of a person’s death.

The State Government of Tasmania has passed legislation aimed at
people who use their vehicles in an irresponsible and dangerous manner
in public places.
The Anti-Hooning law (Police Offences Act 1935) is now in effect, and police have confiscated 649 (as on 15 June 2007) vehicles since September 2004.
If you are caught this is what could happen to you:
- You could have your car confiscated.
- You could be arrested.
- You could lose your licence.
- You could be fined substantially.
- You could lose your freedom.
Here’s how it works.
If you are the driver of a car that is involved:
- In street racing or time trials.
- In making unnecessary and unreasonable noise (turning up your stereo system excessively).
- In an exhibition of speed, acceleration or loss of traction (burn-outs or donuts).
- Or, if the person in control of the vehicle refuses to leave
an area, or returns to an area after being given a direction from a
Police Officer.
The following action can be taken:
- The vehicle can be confiscated and impounded by police for up to two days.
- You may be arrested.
- Towing and storage fees need to be paid before the car is returned.
- You will be required to appear in court at a later date.
- You may be fined substantially.
- You may lose your licence for up to two years.
- You may face imprisonment for up to three months.
If you are caught committing any of the offences listed above for a second or third time, the following penalties apply:
- The vehicle can be confiscated for up to three months, or until
such a time that a resolution in court of the first and subsequent
offences has occurred.
- Police may also seek a forfeiture order (the car may be seized permanently).
Remember, it doesn’t matter if the car you are driving at the time of the offence is yours or not.

New Equipment Launched for Road Safety
Motorists who drink and drive now have an even greater chance of being caught, with the launch of a range of new road safety equipment for Tasmania Police.
The equipment includes extra speed detection devices, breath test equipment and drug wipe kits to assist traffic and uniform police in day-to-day road safety operations.
The new operational equipment, costing $360,000, was launched in Hobart by the Minister for Police and Emergency Management, Mr David Llewellyn.
“Tasmania Police do an outstanding job and it has long been the commitment of this government to ensure that they have the best equipment possible with which to carry out their duties,” Mr Llewellyn said.
“This ongoing commitment to operational policing, and the government’s road safety strategy, will see eight Ultralyte laser speed guns, 32 Lion SD 400 breath testing units, 400 reflective vests and 260 rechargeable torches, fitted with traffic wands, deployed to frontline policing.”
Mr Llewellyn said that in addition to the equipment, the government had purchased more Securetech drug wipe kits.
“Since Tasmania Police began the oral fluid testing in July 2005, more than 700 tests have been conducted on Tasmanian drivers with 234 directed to undertake a blood test following a positive response with the drug wipe,” he said.
“While speed and alcohol remain the major contributing factors to fatal and serious crashes on Tasmanian roads, those who drive with drugs present in their bodies are an equally serious risk to other road users and themselves.”
Also launched were two refurbished multi-purpose Mobile Command Centres, which will form an important part of frontline policing.
The Northern and Western Police Districts will each receive a Toyota Coaster bus.
“These vehicles are not only a Command Centre for use at major incidents on-site,” said Mr Llewellyn.
“They are also a mobile police station that can be used by the Public Order Response Teams, for major event management, road safety operations such as random drug and alcohol testing, and Search and Rescue co-ordination.”
Mr Llewellyn said the equipment will be immediately deployed throughout Tasmania.
“Motorists who contribute to the rate of crashes in our community by drinking and driving stand a greater chance of being caught,” he said.
“All of this equipment we have now provided is aimed at ensuring that the members of Tasmania Police are as well equipped as they can be to do their difficult job as safely as possible and to enforce the laws of this State as efficiently as they can.”

Future Helicopters Get SMART

Helicopters today are considered a loud, bumpy and inefficient mode for day-to-day domestic travel—best reserved for medical emergencies, traffic reporting and hovering over celebrity weddings.
But NASA research into rotor blades made with shape-changing materials could change that view.
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 traffic congestion around the nation's airports. But noise and vibration must be reduced significantly before the public can embrace the idea.
|  | "Today's limitations preclude us from having such an airplane," said William Warmbrodt, chief of the Aeromechanics Branch at NASA's Ames Research Center in California, "so NASA is reaching beyond today's technology for the future." The piezoelectric actuators can change and adapt the rotor blade while in motion. Image Credit: NASA
The solution could lie in rotor blades made with piezoelectric materials that flex when subjected to electrical fields, not unlike the way human muscles work when stimulated by a current of electricity sent from the brain.
Helicopter rotors rely on passive designs, such as the blade shape, to optimize the efficiency of the system. In contrast, an airplane's wing has evolved to include flaps, slats and even the ability to change its shape in flight.
NASA researchers and others are attempting to incorporate the same characteristics and capabilities in a helicopter blade.
NASA and the Defense Advanced Research Projects Agency, also known as DARPA, the U.S. Army, and The Boeing Company have spent the past decade experimenting with smart material actuated rotor, or SMART, technology, which includes the piezoelectric materials. "SMART rotor technology holds the promise of substantially improving the performance of the rotor and allowing it to fly much farther using the same amount of fuel, while also enabling much quieter operations," Warmbrodt said.
|  | There is more than just promise that SMART Rotor technology can reduce noise significantly. There's proof.
The only full-scale SMART Rotor ever constructed in the United States was run through a series of wind tunnel tests between February and April 2008 in the National Full-Scale Aerodynamics Complex at Ames. The SMART Rotor partners joined with the U.S. Air Force, which operates the tunnel, to complete the demonstration.
SMART rotor hub set up for testing in the 40- by 80-foot wind tunnel at NASA's Ames Research Center. Image Credit: NASA
A SMART Rotor using piezoelectric actuators to drive the trailing edge flaps was tested in the 40- by 80-foot tunnel in 155-knot wind to simulate conditions the rotor design would experience in high-speed forward flight. The rotor also was tested at cruise speed conditions of 124 knots to determine which of three trailing edge flap patterns produced the least vibration and noise. One descent condition also was tested.
Results showed that the SMART Rotor can reduce by half the amount of noise it puts out within the controlled environment of the wind tunnel. The ultimate test of SMART rotor noise reduction capability would come from flight tests on a real helicopter, where the effects of noise that reproduces through the atmosphere and around terrain could be evaluated as well.
The test data also will help future researchers use computers to simulate how differently-shaped SMART Rotors would behave in flight under various conditions of altitude and speed.
For now that remains tough to do.
"Today's supercomputers are unable to accurately model the unsteady physics of helicopter rotors and their interaction with the air," Warmbrodt said. "But we're working on it."
