Interstellar space probes: Where's the brakes?!

Fri, 17 Nov 17 00:09:40 -0800

With a miniaturised space probe capable of being accelerated to a quarter of the speed of light, we could reach Alpha Centauri, our nearest star, in 20 to 50 years. However, without a mechanism to slow it down, the space probe could only collect data from the star and its planets as it zoomed past. A theoretical physicist at Goethe University Frankfurt has now examined whether interstellar spacecraft can be decelerated using 'magnetic sails'.

Thu, 16 Nov 17 00:06:40 -0800

Lobachevsky University (UNN) scientists, Associate Professor of the History and Theory of International Relations Department Alexander Petukhov and Head of the Department of Psychophysiology Sofya Polevaya, are studying the modeling of the cognitive dissonance phenomenon. They rely on the theory of information images and a mathematical model developed on the basis of this theory.

Researchers find diffusion plays unusual signaling role in drosophila embryos

Thu, 16 Nov 17 00:07:40 -0800

Researchers have found that diffusion plays an unexpected role in cell differentiation during the early stages of development in the embryos of Drosophila, or fruit flies. Instead of spreading a molecular signal out, it was found that diffusion, facilitated through a carrier molecule, actually concentrates the signal in one place.

NASA detects solar flare pulses at Sun and Earth

Thu, 16 Nov 17 00:00:10 -0800

Two recent studies show how solar flares exhibit pulses or oscillations in the amount of energy being sent out.

This is key information as humans and robotic missions venture out into the solar system, farther and farther from Earth.

Developing a new vaccination strategy against AIDS

Wed, 15 Nov 17 00:04:10 -0800

Infection researchers from the German Primate Center (DPZ) -- Leibniz Institute for Primate Research have in cooperation with international colleagues tested a new vaccination strategy against the HIV-related simian immunodeficiency virus (SIV) in rhesus monkeys. For this, the researchers used a vaccine that consisted of two components.

Three-dimensional nanomagnets for the computer of tomorrow

Wed, 15 Nov 17 00:04:00 -0800

Since the late 60's electronic devices have stored and transmitted information (bits) in two-dimensional circuits. Now, researchers at the University of Cambridge have been able to break this barrier by creating a nanoscale magnetic circuit capable of moving information along the three dimensions of space. This breakthrough could lead to an important increase in storage and processing capacities of electronic devices over those used today.

FIREBIRD II and NASA mission locate whistling space electrons' origins

Wed, 15 Nov 17 00:03:40 -0800

Pluto's hydrocarbon haze keeps dwarf planet colder than expected

Wed, 15 Nov 17 00:10:30 -0800

The gas composition of a planet's atmosphere generally determines how much heat gets trapped in the atmosphere. For the dwarf planet Pluto, however, the predicted temperature based on the composition of its atmosphere was much higher than actual measurements taken by NASA's New Horizons spacecraft in 2015. A new study published November 16 in Nature proposes a novel cooling mechanism controlled by haze particles to account for Pluto's frigid atmosphere.

Speedy collision detector could make robots better human assistants

Tue, 14 Nov 17 00:01:30 -0800

A faster collision detection algorithm could enable robots to work more fluidly in the operating room or at home for assisted living. The algorithm, dubbed 'Fastron,' runs up to 8 times faster than existing collision detection algorithms. It uses machine learning to help robots avoid moving objects and weave through complex, rapidly changing environments in real time.

The anatomy of a cosmic snake reveals the structure of distant galaxies

Mon, 13 Nov 17 00:14:10 -0800

We have a fair understanding of star formation, from the interstellar matter to the diffuse clouds whose gravitational contraction gives birth to stars. But observations of distant galaxies have questioned this picture, the size and mass of these distant stellar nurseries exceeding that of their local counterparts. Astrophysicists from the universities of Geneva and Zurich have tackled this inconsistency and found the first answers thanks to the observation of the cosmic snake.

Tue, 07 Nov 17 00:02:50 -0800

A Chalmers-led team of astronomers has for the first time observed details on the surface of an aging star with the same mass as the Sun. Alma:s images show that the star is a giant, its diameter twice the size of Earth's orbit around the Sun, but also that the star's atmosphere is affected by powerful, unexpected shock waves. The research is published in Nature Astronomy on Oct. 30, 2017.

Astronomers discover sunscreen snow falling on hot exoplanet

Thu, 26 Oct 17 00:08:20 -0700

Astronomers at Penn State have used the Hubble Space Telescope to find a blistering-hot giant planet outside our solar system where the atmosphere 'snows' titanium dioxide -- the active ingredient in sunscreen. These observations are the first detections of this 'snow-out' process, called a 'cold trap,' on an exoplanet. The research provides insight into the complexity of weather and atmospheric composition on exoplanets, and may someday be useful for gauging the habitability of Earth-size planets.

They presented their study in the Classical and Quantum Gravity journal.

How a neutron star collision proves Einstein's 100-year-old General Relativity prediction

Thu, 19 Oct 17 00:04:00 -0700

A hundred years ago, Albert Einstein published his General Relativity theory, predicting the existence of gravitational waves or ripples in space-time, due to violent motion of massive objects in the universe. Collision and merger of two neutron stars should produce gravitational waves and gamma rays simultaneously. Until a few weeks ago, that could not be proven scientifically. Then researchers saw the collision of two neutron stars on Aug. 17, 2017, and everything changed.

Discovered! Neutron star collision seen for the first time

Mon, 16 Oct 17 00:00:50 -0700

A team of Carnegie astronomers provided the first-ever glimpse of neutron stars colliding August 17. With UC Santa Cruz colleagues, they used the Swope telescope at Las Campanas Observatory to discover the light produced by the merger, pinpointing the origin of a gravitational wave signal less than 11 hours after it was detected. They also obtained the earliest spectra of the collision, which may allow them to explain the origin of the universe's heavy elements.
