AV1 beats x264 and libvpx-vp9 in practical use case

Posted Posted in NEWS, Real

Improved video compression is important for delivering digital video files more quickly and with higher quality, while using less bandwidth and storage. Everything from 4K movie streaming to smartphone video chat to laptop screen sharing can be enhanced by making the video files smaller through better compression codecs.

The Alliance for Open Media — a consortium founded in 2015 and made up of video-on-demand providers including Amazon, Facebook, Google, Microsoft and Netflix, along with web browser developers and semiconductor firms — has just released AV1 (also known as AOMedia Video 1), a new open, royalty-free video format that promises to be a significant step forward in compression efficiency.

This wearable device can respond to your thoughts

Posted Posted in NEWS, Real

The signals the wearable picks up are given to a system that analyzes the data, associating specific signals with words.

MIT researchers have created a wearable device called AlterEgo that can recognize nonverbal prompts, essentially “reading your mind.” The system is made up of a device that loops around a user’s ear, follows their jawline, and attaches underneath their mouth, and a computer system. The wearable device has electrodes that pick up neuromuscular signals in your jaw and face that are triggered by internal verbalizations (aka saying words in your head) but can’t be seen by the human eye. These signals are then given to a machine learning system that analyzes the data, associating specific signals with words.

Hacking your brain(scan): security bugs in EEG software open hospitals to attack

Cisco Talos reveals “multiple vulnerabilities” in hardware common at hospitals.

Today, Cisco’s Talos security research group revealed five security vulnerabilities in NeuroWorks, a Windows-based software that is used in multiple electroencephalogram systems sold by Nautus. The Windows-based Natus Xltek NeuroWorks 8 software uses hospitals’ Ethernet networks to connect to EEG devices and integrate with patient data systems, and it is vulnerable to attacks that could allow remote code execution—allowing an attacker to gain access to the data on the device and to other systems on the hospital network—and denial of service. The systems hosting the software could then be used to stage wider attacks on hospital networks.

モスクワ物理工科大学(MIPT)とバイオテクノロジ会社のGEROの研究チームは、ウェアラブルデバイスから取得した活動データをもとに、寿命を計測可能なiPhone向けアプリ「Gero Lifespan」フリーベータ版を公開した。

Gero Lifespanを作った研究者たちは、生物学的年齢と患者の死亡リスクについて調べるために、ウェアラブルデバイスによる活動データと、2003年から2006年の米国国民健康栄養調査(NHANES: National Health and Nutrition Examination Survey)のデータを用いて、患者の1週間の活動をニューラルネットワークで学習させた。

Could tooth-mounted trackers be the next fitness wearables?

Posted Posted in Medical Care, NEWS, Real

Wireless wearable devices, like FitBit, track exercise and pulse, but this is a new departure.

Tooth-mounted trackers that keep a tally on how much food and calories people consume could be the next frontier in fitness monitoring. A research team is already experimenting with the tooth sensors at the Tufts University Biomedical Engineering Department.

“We have extended common RFID [radiofrequency ID] technology to a sensor package that can dynamically read and transmit information on its environment, whether it is affixed to a tooth, to skin, or any other surface,” Fiorenzo Omenetto, Ph.D., corresponding author and the Frank C. Doble Professor of Engineering at Tufts said in a statement.

Reduced-calorie diet shows signs of slowing ageing in people

Posted Posted in Medical Care, NEWS

Most comprehensive study yet demonstrates that cutting people’s energy intake dials down their metabolism.

A study of people who reduced the calories they consumed has found the strongest evidence yet that such restrictions can slow down human metabolism. The results raise hopes that a low-calorie lifestyle — or treatments that mimic the biological effects of restricted eating — could prolong health in old age and even extend life.

Past work in many short-lived animals, including worms, flies and mice, has shown that calorie restrictions reduce metabolism and extend lifespan. But experiments in longer-living humans and other primates are more difficult to conduct and have not yet drawn clear conclusions.

北極は今、1日24時間太陽が昇らない極夜の闇に包まれている。ところがデンマーク気象庁によると、気温は今週に入って零度を超え、同地の冬としては観測史上最高を記録した。 世界最北の陸地にあるモリスジェサップ岬測候所の観測では、グリーンランド東部と北極中部の2月の平均気温は、平年を約15度上回った。
