Fish With Temperature-dependent Sex Determination: How Common Are They?

In vertebrates with separate sexes, sex determination can be genotypic (GSD) or temperature-dependent (TSD). TSD is very common in reptiles, where the ambient temperature during sensitive periods of early development irreversibly determines whether an individual will be male or female. The number of males and females in a population is the sex ratio, a key demographic parameter crucial for population viability.

Physicists Investigate Controversy over Room-Temperature Ice

(PhysOrg.com) -- By confining water in nano-sized spaces, physicists from Leiden University in the Netherlands have turned water into ice at room temperature. While it’s not the first time scientists have created room-temperature ice, Dutch physicists K. B. Jinesh and Joost Frenken hope that their findings will put the controversial subject of water under nanoscale confinement in a new light.

Quantum 'Traffic Jam' Revealed: Findings May Help Get Current Flowing At Higher Temperatures

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory, in collaboration with colleagues at Cornell University, Tokyo University, the University of California, Berkeley, and the University of Colorado, have uncovered the first experimental evidence for why the transition temperature of high-temperature superconductors -- the temperature at which these materials carry electrical current with no resistance -- cannot simply be elevated by increasing the electrons' binding energy.

Room temperature superconductivity: One step closer to the Holy Grail of physics

Scientists at the University of Cambridge have for the first time identified a key component to unravelling the mystery of room temperature superconductivity, according to a paper published in today's edition of the scientific journal Nature.

Animals can adapt to small temperature differences

Animals can sense large changes in temperatures and either move away or die. Now researchers have found they can perceive small variations in temperature as well, and adjust accordingly.

Scientists reveal effects of quantum 'traffic jam' in high-temperature superconductors

This image shows two states of a cuprate high-temperature superconductor simultaneously: Each circle represents the two electrons of a Cooper pair which exist at relatively low energy and can carry current with no resistance. In this image the superc ...

Digital Handheld Calibrator measures pressure, temperature.

July 2, 2008 - Designed to meet line-test application requirements, Heise® PTE-1 can be configured to measure ranges from 0-.25 in. H2O to 0-10,000 psi with Quick Select® modular sensor system. Quick Select® interface modules add temperature measurement with RTDs or thermocouples, while on-board jacks provide measurement of voltage and current. Dual sensor bays and twin LCDs simultaneously display any 2 measurements, and datalogging option enables calibration results to be stored for upload to PC.

Grain Moisture Measurements May Divert Mold, Insect Infestation

Grain storage bins are routinely monitored for temperature to control insect and mold problems. Now an Agricultural Research Service (ARS) scientist and his colleagues at Kansas State University (KSU) have preliminary research findings showing that monitoring carbon dioxide--along with humidity and temperature--also may help detect problems more effectively.

Liquid Metal CPU Heatsink Beats Water Cooling

unassimilatible writes "Bios Magazine is reporting that the world's first commercially available liquid-metal based CPU cooler is about to ship. Danamics, a Danish company, claims that its LM-10 outperforms standard air-cooled heatsinks and most watercooled systems with a mere 1W power draw. 'The liquid metal is a key component in Danamics cooling systems. Liquid metal has two major advantages when cooling high power density heat sources: Firstly it has superior thermo physical properties that decrease temperature — and temperature non-uniformity — on die and across chips. Secondly, the electrical properties of the liquid metal enables efficient, reliable and ultra compact electromagnetic pumping without the use of moving parts, shafts, seals, etc.

StarTrak Bolsters Intellectual Property With Key New Patent Applications

(EMAILWIRE.COM, August 23, 2008 ) Morris Plains, NJ – StarTrak Systems, a subsidiary of Alanco Technologies, Inc. (NASDAQ: ALAN), and the leader in transport refrigeration wireless monitoring and control systems, today announced that it has added three key patent applications to its intellectual property portfolio, now totaling fourteen pending and issued patents covering a broad spectrum of functionality related to wireless refrigerated transport (“reefer”) monitoring, including: • Sensing rapid reefer fuel loss and monitoring re-fueling events, allowing operators to detect leakage or theft and evaluate fuel consumption and costs • Capability to remotely broadcast multiple reefer power on and off settings, eliminating operator involvement • Remote temperature setting, allowing customers to assure reefer temperature is consistent with shi

How Hot Are The Planets in Our Solar System?

Venus ranks No. 1 for average temperature because its dense atmosphere acts as a greenhouse and heats the surface to above the melting point of lead (3,280 degrees Celsius). Don't try to visit.

Matsushita Develops Low-cost Recycling System for Low-concentration Solvents

Highly efficient recovery technology based on humidification: The temperature of the exhaust gas is lowered by a liquid concentrator, and the resultant gas is sprayed with water to be humidified. Then, the solvent is dissolved in condensate to be recovered. The method can efficiently recover low concentration solvents as well.
