Small particles can have big consequences for electronics in space missions

Several space missions planned by the European Space Agency and NASA have their target set on Jupiter and its moons. The extraordinarily harsh radiation environments in the Jovian system will set some strict requirements for the electronics inside the spacecraft. To ensure the proper function of the spacecraft, it is important to understand and quantify the physical mechanisms causing the errors in the electronics, specifically by electrons. In her dissertation at University of Jyväskylä Maris Tali proved that single light particles, like electrons and low energy protons are capable of inducing effects in electronics that are usually not considered.

Observing Gaia from Earth to improve its star maps

Everything will connect to the internet someday, and this biobattery could help

In the future, small paper and plastic devices will be able to connect to the internet for a short duration, providing information on everything from healthcare to consumer products, before they are thrown away. Researchers at Binghamton University, State University of New York have developed a micro biobattery that could power these disposable sensors.

Floating power plants

Paper, tin cans, glass—the world recycles as much as possible. So why not declare the greenhouse gas carbon dioxide (CO2) a recycling product as well? Liquid fuels based on carbon will continue to play an important role in the future—despite international efforts to reduce them. So it seems sensible to recover the CO2 exhaust from the environment and use it again.

Physical inactivity risky for children and pre-teens

Cardio-respiratory capacity in children has dropped by 25 percent in 20 years, according to a study by the University of Adelaide in Australia. There are multiple reasons for this, from the social environment and the decreasing number of play areas to a more academic approach towards teaching physical education and the spread of new technologies. But at what age do children lose the desire to exercise? Researchers from the University of Geneva (UNIGE), Switzerland, followed 1,200 Geneva pupils, aged eight to 12, for two years. The team found out that from the age of 9, the positive reasons for exercising—it's fun and good for your health—begin to be replaced by more displaced incentives: to get a good mark or improve your image with others. These results, which are published in the journal Psychology of Sport and Exercise, call for a more detailed analysis of how PE is taught in schools to counter physical inactivity leading to a sedentary lifestyle from an early age.

New research explores the mechanics of how birds flock

Wildlife researchers have long tried to understand why birds fly in flocks and how different types of flocks work. A new study from the University of North Carolina at Chapel Hill explores the mechanics and benefits of the underlying flock structure used by four types of shorebirds. Understanding more about how these birds flock moves researchers a step closer to understanding why they flock.

Tolerance to stress is a 'trade-off' as fruit flies age

The consequences of aging are damage and degeneration of cells, which leads to loss of function, vulnerability to disease, and eventually, death. A hallmark of the aging process is the progressive decline of the nervous system, including both motor and cognitive functions. To complicate matters, natural variation in aging populations makes it difficult to study the factors that contribute to behavioral decline. Because the human aging process is typically slow, elucidating aging biomarkers and predicting individual differences has proven to be very challenging.

Salmon get a major athletic boost via a single enzyme

Salmon species, known for undertaking arduous upstream migrations, appear to owe a good deal of their athletic ability to the presence of a single enzyme.

Using population genetics, scientists confirm origins of root rot in Michigan ornamentals

Floriculture, the growing of flowering and ornamental plants for gardens and floristry, is an economically important industry in Michigan, which ranks third in the United States for the wholesale value of floriculture products. The health of these crops is threatened by many diseases, including Pythium ultimum, a water mold that infects the roots of popular plants including poinsettia and geranium. The mold results in plant stunting, reduced plant quality, and root and crown rot. Despite educated efforts to improve control of this pathogen, root rot occurs annually for many growers.

A combination of insecticides and mites weakens honeybees

Today, scientists at the Institute of Bee Health of the University of Bern and the honeybee research association COLOSS have published an article in the peer-reviewed journal Scientific Reports that shows a synergistic time-lag interaction between the parasitic mite Varroa destructor and neonicotinoid insecticides reducing survival of winter honeybees, Apis mellifera. This article emphasizes the need to develop sustainable agricultural and apicultural schemes.
