First winner in space elevator competition
The contest requires their machines to climb 2,953 feet (nearly 1 kilometer) up a cable slung beneath a helicopter hovering nearly a mile high; the vehicle from the Kansas City-based LaserMotive zipped up to the top in just over four minutes and immediately repeated the feat, qualifying for at least a $900,000 second-place prize

First space hotel taking bookings for 2012 opening
Space tourism is nearing, with the first space hotel set to open in 2012; the Barcelona-based company is already taking bookings; the cost of three nights (plus a two-month training course on a Caribbean island beforehand) will be $4.4 million per guest

Robot fish could monitor water quality
Michigan State University researchers develop robots that use advanced materials to swim like fish to probe underwater environments; robotic fish — perhaps schools of them operating autonomously for months — could give researchers far more precise data on aquatic conditions, and the quality — and security — of the water supply

African desert rift confirmed as new ocean is forming
Geologists show that seafloor dynamics are at work in splitting African continent; scientists from several countries have confirmed that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world’s oceans, and the rift is indeed likely the beginning of a new sea

Space elevator competition to test alternatives to rocketry
The space elevator idea envisions replacing rockets with electrically powered vehicles which would run up and down a cable anchored to a ground structure and extending thousands of miles up to a mass in geosynchronous orbit — the kind of orbit communications satellites are placed in to stay over a fixed spot on the Earth; space elevator competition being held this week in the the Mojave Desert

New technology to boost food security
A scientist in the Philippines develops a new method for keeping food fresh; brine-immersion freezing, or BIF, allows fish and meat can be stored for two to three days in styrofoam boxes without using ice, and up to six months when stored in freezers or chillers

Day of quantum communications in the theater nears
The challenges so far with free space optical links, which use fibre optics for transmission, have been the turbulence or distortions from temperature differences that cause motion or wind in the atmosphere; researchers have established an optical link without distortion in test situations at a distance of 35km in stationary and flight situations

Nuclear energy central to climate debate
There are 104 power reactors in 31 states, providing one-fifth of the U.S. electricity; they are also producing 70 percent of essentially carbon-free power and are devoid of greenhouse gas emissions; a study by the industry-supported Electric Power Research Institute says 45 new reactors are needed by 2030; the Energy Information Administration puts the number at 70; an analysis by the Environmental Protection Agency (EPA) assumes 180 new reactors by 2050 for an 80 percent decline in greenhouse gas emissions

R. Brooks's robots are called upon to inspect pipes at nuclear power plants
The growing interest in nuclear power is good news for Brooks, a maker of remotely operated robotic inspection devices for pipes, especially in nuclear power plants; all power plants have intricate systems of pipes and systems whose internal condition is impossible to inspect by human eyes

Counterfeit chips may hobble advanced weapons
While most computer security efforts have until now been focused on software, tampering with hardware circuitry may ultimately be an equally dangerous threat; the Pentagon now manufactures in secure facilities run by American companies only about 2 percent of the more than $3.5 billion of integrated circuits bought annually for use in military gear

The brief
Vetting a chip with a hidden agenda is not easy, and chip makers cannot afford to test every chip; also, today only Intel and a few other companies still design and manufacture all their own chips in their own fabrication plants; other chip designers — including LSI Corp. and, most recently, Sony — have gone “fabless,” outsourcing their manufacturing to off-shore facilities known as foundries

Earthquake-proof airport terminal in Istanbul airport
Large swaths of Turkey are earthquake prone; the 1999 Kocaeli earthquake, for example, killed 17,000 people, injured 50,000, and destroyed 27,000 buildings, leaving 500,000 homeless; estimates of property losses range from $3 billion to $6.5 billion; engineers claim they have made the terminal at Istanbul Sabiha Gokcen International Airport earthquake-proof

Foundation for U.S. Breakthroughs Feels Shakier to Researchers
With each dollar of its grants, the National Institutes of Health —the world’s largest funder of biomedical research —generates, on average, $2.56 worth of economic activity across all 50 states. NIH grants also support more than 400,000 U.S. jobs, and have been a central force in establishing the country’s dominance in medical research. Waves of funding cuts and grant terminations under the second Trump administration are a threat to the U.S. status as driver of scientific progress, and to the nation’s economy.
