Physics news

New theory—If we want to detect dark matter we might need a different approach

Physicists suggest a new way to look for dark matter: They believe that dark matter particles annihilate into so-called dark radiation when they collide. If true, then we should be able to detect the signals from this radiation.

New data from Antarctic detector firms up cosmic neutrino sighting

Researchers using the IceCube Neutrino Observatory have sorted through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year to gather powerful new evidence in support of 2013 observations confirming the existence of cosmic neutrinos.

A detector shines in search for dark matter

Results of the XENON100 experiment are a bright spot in the search for dark matter. The team of international scientists involved in the project demonstrated the sensitivity of their detector and recorded results that challenge several dark matter models and a longstanding claim of dark matter detection. Papers detailing the results will be published in upcoming issues of the journals Science and Physical Review Letters.

Snaring a dark energy 'chameleon': Is dark energy hiding from us? Matter may be screening it from our view

If dark energy is hiding in our midst in the form of hypothetical particles called "chameleons," Holger Müller and his team at the University of California, Berkeley, plan to flush them out.

A new design for an easily fabricated, flexible and wearable white-light LED

Researchers from National Chiao Tung University, Taiwan have created highly flexible, efficient white LEDs with potential use in wearable displays and non-flat surfaces, such as curved and flexible television screens. While the design itself is new, the LED was completely fabricated from pre-existing technologies, allowing others to easily replicate and build on the platform.

Nanocrystals don't add up for reactor materials

Lawrence Livermore researchers have found that nanocrystalline materials do not necessarily resist radiation effects in nuclear reactors better than currently used materials.

New probe can monitor shock from hemorrhages without drawing blood

It's inefficient to periodically draw blood from someone's neck to check oxygen levels, especially when that person is in an intensive care unit for massive blood loss. Yet the invasive procedure is currently the go-to method for monitoring the status of hypovolemic and septic shock, the common consequence of hemorrhage that causes poor oxygen circulation and can lead to organ failure and death. In a quest for a better monitoring technique, researchers from the University of Electronic Science and Technology of China have developed a portable probe that uses near-infrared light to measure blood oxygen saturation in the tissue surrounding the central internal jugular vein in the neck – allowing doctors to continuously monitor a patient's recovery from shock without the hassle of continuously drawing and analyzing blood.

Small, inexpensive, and incredibly resilient: A new femtosecond laser for industry

A team at the University of Warsaw, Faculty of Physics has created a laser capable of generating ultrashort pulses of light even under extremely difficult external conditions. This unique combination of precision and resilience is due to the fact that the whole process of generating femtosecond laser pulses takes place within a specially-selected optical fiber.

Earth news

Research shows seawater involved in making diamonds beneath the Northwest Territories

Some of the rich diamond deposits in the Northwest Territories may have been formed as a result of ancient seawater streaming into the deep roots of the continent, transported by plate tectonics, suggests new research from an international team of scientists in Canada, the U.S. and the U.K. The discovery further highlights the role played by plate tectonics in "recycling" surface materials into deep parts of the earth, building on the groundbreaking discovery by a University of Alberta team last year of vast quantities of water trapped more than 500 kilometres underground.

Warming climate is deepening California drought

A new study says that global warming has measurably worsened the ongoing California drought. While scientists largely agree that natural weather variations have caused a lack of rain, an emerging consensus says that rising temperatures may be making things worse by driving moisture from plants and soil into the air. The new study is the first to estimate how much worse: as much as a quarter. The findings suggest that within a few decades, continually increasing temperatures and resulting moisture losses will push California into even more persistent aridity. The study appears this week in the journal Geophysical Research Letters.

World should heed lessons from Hurricane Katrina, economist says

A decade after Hurricane Katrina hammered America's Gulf Coast, measures are being taken there to protect against similar devastation from natural disasters—as well as against long-term, gradual impacts resulting from climate change.

The downs and ups of mountain building

In the D'Entrecasteaux Islands off Papua New Guinea, the rocks are giving rise to new ideas about the ways in which mountain chains form. A new scientific model inspired by data from the islands shows how the seemingly opposite processes of tectonic compression and extension can take place in the same region.  It also shows how sections of earth's crust that have been pushed deep under the surface can reverse course and rise in what in the geological time scale would be an instant. The model has implications for the understanding of how many mountain belts form.

World breaks new heat records in July: NOAA scientists

The world broke new heat records in July, marking the hottest month in history and the warmest first seven months of the year since modern record-keeping began in 1880, US authorities said Thursday.

Boreal forests challenged by global change

Management of boreal forests needs greater attention from international policy, argued forestry experts from the International Institute for Applied Systems Analysis (IIASA), Natural Resources Canada, and the University of Helsinki in Finland in a new article published this week in the journal Science. The article, which reviews recent research in the field, is part of a special issue on forests released in advance of the World Forestry Congress in September.

Architecture of aquifers: Chile's Atacama Desert

The Loa River water system of northern Chile's Atacama Desert, in the Antofagasta region, exemplifies the high stakes involved in sustainable management of scarce water resources. The Loa surface and groundwater system supplies the great majority of water used in the region, and meets much of the municipal and agricultural demands. It is vital to regional copper mining, which constitutes ~50% of Chile's copper production, which in turn supplies one-third of the world's copper needs. However, a key property of the Loa system is the scarcity of surface water.

Europe hit by one of the worst droughts since 2003

Much of the European continent has been affected by severe drought in June and July 2015, one of the worst since the drought and heat wave of summer of 2003, according to the latest report by the JRC's European Drought Observatory (EDO).

Using traces of ancient comet to explore the history of the Solar System

Space: the final frontier – never were truer words spoken. We have currently explored less than 0.01% of the universe; in fact, it's much less than that. We've actually explored about as close to zero percent as it's possible to get. With so much left to discover, space is likely to remain a mystery for quite some time. But with the support of technological advances, scientists are making real progress, particularly when it comes to what planetary scientists regard as remainders from the 'building blocks of the solar system' – comets. 

How did Jupiter and Saturn form? The answer may lie with the humble pebble

After many decades of exploring the solar system, we still have much to learn about our closest celestial neighbours. One of the biggest remaining puzzles is how the giant gas planets managed to form in the early days of the solar system, with the leading theories suggesting that they could have formed by repeated collisions between objects about ten times smaller than our own moon.

Electrospray solves longstanding problem in Langmuir-Blodgett assembly

In the 1930s, Irving Langmuir and his colleague Katharine Blodgett were working long days in the General Electric Company's research laboratory. Together, they discovered that by spreading molecules with volatile organic solvents on the surface of water, they could create a one-molecule-thick film and use it as an anti-reflective coating for glass. Later named Langmuir-Blodgett assembly, this thin-film fabrication technique became popular for creating molecule or nanoparticle monolayers and is commonly used until this day.

Horizontal transfer of mitochondria in sickness and in health

(Medical Xpress)—Two of the most enticing ideas in cells biology have recently converged to create a paradigm shift of epic proportions. The first is that not only is it possible for mitochondria to emigrate from their host cell, they are in fact exchanged among cells much more regularly than has ever been imagined. The second is that while happenstance mutations are clearly associated with different aspects of a litany of cancers, the canonical force consistently driving tumor initiation, progression, and metastasis is now broadly understood to be the metabolic fickleness of their mitochondria.

Systematic review shows 'smart drug' modafinil does enhance cognition

The drug modafinil was developed to treat narcolepsy (excessive sleeping), but it is widely used off-licence as a 'smart drug' to promote cognitive enhancement, where qualities such as alertness and concentration are desired to assist someone with, for example, exam preparation. Past studies on sleep-deprived individuals have shown a strong positive effect of modafinil on these functions, but there has been less attention and scientific consensus on the drug's overall effectiveness as a cognitive enhancer in people that are not sleep-deprived - presumably the majority of people taking it. Now, a new systematic review, published online in the peer-reviewed journal European Neuropsychopharmacology shows that modafinil does indeed confer significant cognitive benefits in this group, at least on a particular subset of tasks.

Extracorporeal life support is 'bridge-to-life' for patients with sudden onset cardiogenic shock

Cardiogenic shock is when a patient's heart is so severely damaged that it is no longer able to pump blood to the organs of the body. When this occurs, mechanical circulatory support may be the only hope for survival. While different options are available, recovery of cardiac function with extracorporeal life support (ECLS) differs dramatically depending upon whether the cardiogenic shock results from an acute episode, such as a heart attack, or chronic cardiac deterioration. The results of a new study are reported in The Journal of Thoracic and Cardiovascular Surgery, the official publication of the American Association for Thoracic Surgery (AATS).

How long have primates been infected with viruses related to HIV?

Disease-causing viruses engage their hosts in ongoing arms races: positive selection for antiviral genes increases host fitness and survival, and viruses in turn select for mutations that counteract the antiviral host factors. Studying such adaptive mutations can provide insights into the distant history of host-virus interactions. A study published on August 20th in PLOS Pathogens of antiviral gene sequences in African monkeys suggests that lentiviruses closely related to HIV have infected primates in Africa as far back as 16 million years.
