State of the Climate in Asia 2024

The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …

A little low?

A global positioning system (gps) receiver, a laptop computer and some software can be used to warn pilots if they are flying too close to the ground. California-based Dubbs and Severino has developed the software from technology originally researched by the US National Aeronautics and Space Administration. Military pilots are …

Cool magnets

ever since the first patent for mechanical refrigeration was granted to Jacob Perkins in 1834, the quest for more efficient and faster refrigeration has been on. Lately, the emphasis has also been on making refrigeration less damaging to the environment as the chloroflourocarbon (cfc) gases are harmful to the ozone …

Safe as milk

Ethyl lactate, an ecologically benign chemical, is all set to replace dangerous solvents

Safe as milk

a simple substitute made from ingredients found in a glass of wine and a milk bottle could have easily replaced the hazardous organic chemicals used in everything from paint thinners to solvents years ago, say scientists. But this substitute, till now, was far too expensive to be an economically-feasible alternative …

Keep talking

the easiest mode of communication, talking, and the one that we have always taken for granted, can prove to be difficult for many people. Those who have difficulties with speech are learning to pronounce words more clearly using an artificial palate that "tells' them exactly what their tongue is doing. …

Light relief

Researchers have developed a hybrid pollution sensor in the form of a bioluminescent bacteria placed on a standard microchip. A common bacteria is genetically altered to glow in the presence of certain pollutants. This is placed in a porous polymer on the surface of a chip which contains a photo-detector. …

Charged up

Detection of electric charge has now been made simpler with the development of a new nanometer-scale mechanical electrometer. Consisting of three electrodes, a mechanical element which moves in response to the force experienced by the electrodes in the presence of charge and a displacement detector to monitor the motion. Developed …

Structuring made easy

Nuclear Magnetic Resonance is a widely used technique to study the structure of materials ranging from proteins to catalysts. These machines have become an essential part of any laboratory. But now, the next-generation machines are all set to change this approach. These will use extremely powerful magnets and cost about …

Power of wood

Scientists at Fraunhofer Safety and Energy Technology, Germany, have devised a method to convert unwanted fuel into gas. The gas can be used to generate electricity and heat. The process uses "fluidised bed gasification' to convert the wood into gas that is cooled and used as engine fuel. Its overall …

Small wonders

human hands may soon become obsolete in the near future, because of a revolutionary technology that allows miniature robots

Ice talk

A talking refrigerator will go on sale in Japan very soon. Developed by one of the nation's technological giants, Matsushita, this "hi-tech' fridge warns its user if the food stored inside is in danger of going bad. Sensors linked to a microprocessor monitor the energy efficiency of the internal cooling …

Super power

if there is one device that has truly revolutionised our lives, it is the transistor. Since its invention in the late 1940s, this device has made the entire microelectronics revolution

Careful picking

A mechanical harvester with nylon arms is being tested by the US-based orange growers. The machine gently shakes ripe fruit off the tree. The growers are using the technique originally developed for picking blackberries. If the machine is found successful, it would help orange growers in the US to compete …

Crystal clear

sensors could soon become more accurate and economical with the help of a new material. These sensors could be used in a variety of applications such as to determine the levels of various compounds like glucose in the blood or the levels of toxic elements in drinking water. John Holz …

Flying safely

the mid-air collision over Charkhi Dadri near Delhi might not have taken place if the Saudia and Kazakhstan Airlines had been using a Traffic Alert Collision Avoidance System (tcas). tcas or Airborne Collision Avoidance System (acas) is the air-to-air communication system that issues audio-visual warnings to the pilots whenever two …

Innervating chips

Neurophysicist Jerome Pine and his colleagues have assembled the first neurochip at the California Institute of Technology, Pasadena, USA. A neurochip is silicon chip with living nerve cells or neurones. The scientists bored 16 tiny wells in the chip. An embryonic rat brain cell was introduced in each well. As …

Weld on

engineers have been attempting for long to develop a system so that welding could be performed underwater. A newly observed

Coping with rejection

studies in the us show that special proteins can prevent rejection of transplanted organs in monkeys without the need of immune suppressant drugs. If the same technique applies to human, patients would not have to take long-term drugs to avoid rejection of the foreign tissue. A brief course of protein …

Star s blueprint

the magnetic field of a star has been mapped for the first time by a team of researchers at the National Radio Astronomy Observatory, usa . The team led by Kemball and P Diamond has mapped the magnetic field of tx Camelopardalis ( tx Cam), a red giant star about …

Success matters

winning is important. A chemical signal that stimulates the nerves of crayfish, who win fights can have completely the opposite effect in those that lose. The findings by scientists in Atlanta, Georgia, show that events have the power to change the way the nervous system functions. The research might even …
