Humans colonized diverse environments in Southeast Asia and Oceania during the Pleistocene

Investigations into what it means to be human have often focused on attempts to uncover the earliest material traces of 'art', 'language', or technological 'complexity'. More recently, scholars have begun to argue that more attention should be paid to the ecological uniqueness of our species. A new study reviews the palaeoecological information associated with hominin dispersals into Southeast Asia and Oceania throughout the Pleistocene (1.25 Ma to 12 ka). from All Top News -- ScienceDaily https://www.sciencedaily.com/releases/2019/01/190128122236.htm

Converting Wi-Fi signals to electricity with new 2D materials

Imagine a world where smartphones, laptops, wearables, and other electronics are powered without batteries. Researchers have taken a step in that direction, with the first fully flexible device that can convert energy from Wi-Fi signals into electricity that could power electronics. from All Top News -- ScienceDaily https://www.sciencedaily.com/releases/2019/01/190128111718.htm

Apple Working on Games Service Subscription for the App Store: Report

Apple is working on a games service subscription for the App Store. This planned service would function like a 'Netflix for games', allowing users to pay a regular subscription fee for a host of titles. from RSS Feeds | APPLE - RSS Feed - NDTV Gadgets360.com https://gadgets.ndtv.com/apps/news/apple-working-on-games-service-subscription-for-the-app-store-report-1984577

Better safeguards for sensitive information

Despite being the most advanced quantum technology, secure encryption of information units based on a method called quantum key distribution (QKD) is currently limited by the channel's capacity to send or share secret bits. Scientists now show how to better approach the secret key capacity by improving the channel's lower boundary. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2019/01/190128101106.htm

3D virtual slicing of an antique violin reveals ancient varnishing methods

Italian violin-making masters of the distant past developed varnishing techniques that lent their instruments both an excellent musical tone and impressive appearance. Scientists have now developed a non-invasive 3D-scanning approach to gain insights into the main morphological features of the overlapping finishing layers used on violins. This could help scientists rediscover the procedures employed by ancient violin masters. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2019/01/190128101102.htm

Quantifying how much quantum information can be eavesdropped

The most basic type of quantum information processing is quantum entanglement. Researchers have now provided a much finer characterization of the distributions of entanglement in multi-qubit systems than previously available. These findings can be used in quantum cryptography to estimate the quantity of information an eavesdropper can capture regarding the secret encryption key. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2019/01/190128101120.htm

Manipulating cell networks with light: New frontiers in optical microscopy

A new optical microscope system called SIFOM (Stimulation and Imaging-based Functional Optical Microscopy) can stimulate multiple cells simultaneously by a holographic method and monitor cell activity after the stimulation using 3D (three-dimensional) measurements based on fluorescence holography. This system has potential applications as a tool for the reconstruction of lost nerve pathways, constructing artificial neural networks, and food resources development. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2019/01/190128091447.htm

Scientists observe a new form of strange matter

In a discovery that could provide new insights into the origin of mass in the universe following the Big Bang, scientists have used experiments with kaons and helium-3 to experimentally demonstrate, for the first time, the existence of an exotic nucleus containing two protons and a bound kaon. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2019/01/190128091440.htm
