From birth, it takes humans almost two decades to reach adulthood; for a fruit fly, it takes only about 10 days. During a fly embryo's initial stages of development, the insect looks different from minute to minute, and its body plan is defined in just a few hours. Caltech researchers have now gained new insights into how a fly's genes influence this fast period of development—work that ultimately
Enantiomeric molecules resemble each other like right and left hands. Both variants normally arise in chemical reactions. But frequently, only one of the two forms is effective in biology and medicine. Completely converting this mixture into the desired enantiomer has been deemed impossible. However, via a photochemical method, a team from the Technical University of Munich (TUM) has now achieved
Apollo 8 was supposed to be a test flight, meant to simulate atmospheric re-entry from the moon but never meant to go there. Hurtling toward Earth at 2,407.5 miles per hour is hairy business and NASA, having never done so before, needed practice. But then the USSR successfully launched two of its own moonshots (unmanned Zond 5 and 6) on the heels of President Kennedy's call for men on the moon by
The properties of matter are typically the result of complex interactions between electrons. These electrically charged particles are one of the fundamental building blocks of nature. They are well researched, and theoretical physics has determined the electronic structure of the majority of matter. However, the behavior of matter under extreme conditions is still largely unexplained. Such conditi

More than two-thirds of Canada's biodiversity is made up of species that occur within the country's borders only at the very northern edge of their range. Biologists have long debated how much effort should be dedicated to conserving these 'edge populations.' One argument in their favor is that they may be especially well suited to lead northward range shifts for their species as the climate warms
Harvester ants that eat weed seeds on the soil's surface can help farmers manage weeds on their farms, according to an international team of researchers, who found that tilling less to preserve the ants could save farmers fuel and labor costs, as well as preserve water and improve soil quality.
Infants and toddlers in low-income, rural areas may be at higher risk for second- and third-hand smoke than previously reported, according to new research.
Researcher shows the two most common means of resistance to BRAF and MEK inhibitors are actually connected processes and can be targeted by other therapies.
New research highlights a previously unexplored consequence of the global proliferation of wind energy facilities: a wake effect from upwind facilities that can reduce the energy production of their downwind neighbors.
A closer look at small earthquakes that took place at the Oroville Dam in California's Sierra Nevada foothills in February 2017 — near the time when the dam's spillway failed — suggest that the seismic activity was related to reservoir discharge that opened and closed fractures in the rock below the spillway.
Researchers have made a discovery about human papillomavirus (HPV) that could lead to new treatments for cervical cancer and other cancers caused by the virus, the most common sexually transmitted disease.
Scientists have deciphered how some types of 'swimming' bacteria have evolved to be able to escape when trapped in small spaces. The discovery could pave the way to finding new methods to stop the spread of certain bacteria, including species that cause food poisoning and stomach ulcers.
