WhatsApp faces legal challenge over privacy policy in India
NEW DELHI — WhatsApp is facing a legal challenge in India, its biggest market, after a petition was filed Thursday before Delhi High Court over the upcoming change in the Facebook-owned app’s data sharing policy. The petition alleges the new terms that WhatsApp requires its roughly 450 million users in the country to accept is a violation of their fundamental rights to privacy and poses a threat to national security. Through an in-app alert, WhatsApp has asked users in recent days to agree to new terms of conditions that grants the app the consent to share some personal data about them such as their phone number and location with Facebook. Users will have to agree to these terms by Feb.8, 2021 if they wish to continue using the app, the alert said. The change has been...

NYUAD has made an exhaustive review of the scientific literature surrounding the natural production of light, called bioluminescence.
NYUAD researchers shed new light on mysteries behind emission of fireflies
ABU DHABI — A team of researchers from the New York University Abu Dhabi’s (NYUAD) Smart Materials Lab (SML) led by Professor of Chemistry Panče Naumov has conducted an exhaustive review of the scientific literature surrounding the natural production of light, called bioluminescence, and developed conclusions that will help others in the field to direct their research and uncover the mysteries behind this natural phenomenon.In the new study "The Elusive Relationship Between Structure and Color Emission in Beetle Luciferases," which is featured on the cover of the journal Nature Reviews Chemistry, Naumov and colleagues provide the most comprehensive critical overview of the field of the bioluminescence of beetles, including fireflies, to date.The NYUAD researchers, including...

Researchers regenerate underwater biodiversity destroyed by human activity
BRUSSELS — In this special edition of Futuris, we report on one of the missions that the European Union is launching to find solutions to the main challenges of our time.Five missions shape this initiative, part of the incoming Horizon Europe initiative which will begin in 2021: Carbon-neutral and Smart Cities, Soil Health and Food, Adaptation to climate change, the Fight against Cancer and the Protection of our Oceans and Inland waters.Our seas, oceans, coastal zones, glaciers and inland waters produce around half of the oxygen we breathe and provide 16% of the animal proteins we consume. But these rich and fragile ecosystems are under threat from climate change, pollution, over-fishing and tourism.How do we protect these environments and preserve their socio-economic value?Pascal Lamy...

Satellites are mapping out every tree on Earth using AI
By Rosie FrostScientists have mapped 1.8 billion individual tree canopies across millions of kilometers of the Sahel and Sahara regions of West Africa. It is the first time ever that trees have been mapped in detail over such a large area.So how was it possible? Researchers analyzed a huge database of satellite images using artificial intelligence. They employed neural networks, which are able to recognize objects, like trees, based on their shapes and colors.To train it, the AI system was shown satellite images where trees had been manually traced. This involved lead author Martin Brandt going through the arduous process of identifying and labeling nearly 90,000 trees himself, beforehand.From these images, the computer learned what a tree looked like and could pick out individual canopies...

A controllable membrane to pull carbon dioxide out of exhaust streams
By David L. ChandlerA new system developed by chemical engineers at MIT could provide a way of continuously removing carbon dioxide from a stream of waste gases, or even from the air. The key component is an electrochemically assisted membrane whose permeability to gas can be switched on and off at will, using no moving parts and relatively little energy.The membranes themselves, made of anodized aluminum oxide, have a honeycomb-like structure made up of hexagonal openings that allow gas molecules to flow in and out when in the open state. However, gas passage can be blocked when a thin layer of metal is electrically deposited to cover the pores of the membrane. The work is described in the journal Science Advances, in a paper by Professor T. Alan Hatton, postdoc Yayuan Liu, and four...

Scientists uncover new clues about Parkinson’s disease
By Jennifer MichalowskiAs the brain processes information, electrical charges zip through its circuits and neurotransmitters pass molecular messages from cell to cell. Both forms of communication are vital, but because they are usually studied separately, little is known about how they work together to control our actions, regulate mood, and perform the other functions of a healthy brain.Neuroscientists in Ann Graybiel’s laboratory at MIT’s McGovern Institute for Brain Research are taking a closer look at the relationship between these electrical and chemical signals.“Considering electrical signals side by side with chemical signals is really important to understand how the brain works,” said Helen Schwerdt, a postdoc in Graybiel’s lab.Understanding that relationship is also...

Validating the physics behind the new MIT-designed fusion experiment
David L. ChandlerTwo and a half years ago, MIT entered into a research agreement with startup company Commonwealth Fusion Systems to develop a next-generation fusion research experiment, called SPARC, as a precursor to a practical, emissions-free power plant.Now, after many months of intensive research and engineering work, the researchers charged with defining and refining the physics behind the ambitious tokamak design have published a series of papers summarizing the progress they have made and outlining the key research questions SPARC will enable.Overall, says Martin Greenwald, deputy director of MIT’s Plasma Science and Fusion Center and one of the project’s lead scientists, the work is progressing smoothly and on track. This series of papers provides a high level of confidence...

IQM staff publishes a quantum-computer breakthrough in Nature
ESPOO, Finland — Prof. Mikko Möttönen's university research group and collaborators have engineered a fast and ultra-sensitive nanoscale bolometer that detects very faint microwave radiation. In fact, the radiation detected is so weak that heating up a cup of coffee at room temperature, for 1°C in a microwave oven would have taken 50 septillion times more energy. That is a 5 followed by 25 zeroes."The device is so tiny; it could even fit inside a bacterium," says Möttönen who is a joint Professor of Quantum Technology at Aalto University and VTT, and also a Co-Founder of IQM.The new bolometer can measure the energy of photons much more accurately and faster than before. This is essential for quantum computers, since measuring the energy of qubits, the quantum bits, is...

Engineers produce a fisheye lens that’s completely flat
By Jennifer ChuTo capture panoramic views in a single shot, photographers typically use fisheye lenses — ultra-wide-angle lenses made from multiple pieces of curved glass, which distort incoming light to produce wide, bubble-like images. Their spherical, multipiece design makes fisheye lenses inherently bulky and often costly to produce.Now engineers at MIT and the University of Massachusetts at Lowell have designed a wide-angle lens that is completely flat. It is the first flat fisheye lens to produce crisp, 180-degree panoramic images. The design is a type of “metalens,” a wafer-thin material patterned with microscopic features that work together to manipulate light in a specific way.In this case, the new fisheye lens consists of a single flat, millimeter-thin piece of glass...

Astronomers may have found a signature of life on Venus
By Jennifer Chu The search for life beyond Earth has largely revolved around our rocky red neighbor. NASA has launched multiple rovers over the years, with a new one currently en route, to sift through Mars’ dusty surface for signs of water and other hints of habitability.Now, in a surprising twist, scientists at MIT, Cardiff University, and elsewhere have observed what may be signs of life in the clouds of our other, even closer planetary neighbor, Venus. While they have not found direct evidence of living organisms there, if their observation is indeed associated with life, it must be some sort of “aerial” life-form in Venus’ clouds — the only habitable portion of what is otherwise a scorched and inhospitable world. Their discovery and analysis is published today in the journal...
