THE MIT HUMANOID ROBOT: A DYNAMIC ROBOTIC THAT CAN PERFORM ACROBATIC BEHAVIORS
Creating robots that can perform acrobatic movements such as flips or spinning jumps can be highly challenging. Typically, in fact, these robots require sophisticated hardware designs, motion planners and control algorithms.
USING WASTE HEAT TO POWER AN ENVIRONMENTALLY SUSTAINABLE FUTURE
In his most recent published research, appearing in Applied Thermal Engineering, City, University of London’s Dr. Martin White explores a novel organic Rankine cycle system, based on a two-phase expansion through numerical simulations of the system.
GREEN ENERGY MAY REQUIRE INCREASED MINING IN THE U.K. IN THE SHORT TERM, EXPERTS SAY
As countries race to become carbon neutral, a new commentary from Prof Richard Herrington, Head of Earth Sciences Department at the Natural History Museum, has examined the cost of our green future and concludes that we may need accept an increase in UK mining in the short term.

EVIDENCE FOUND OF SUPERFLUIDITY IN EXTREMELY COLD 2D GAS OF FERMIONS
A team of researchers working at the Institut für Laserphysik, Universität Hamburg, has found evidence of superfluidity in an extremely cold 2D gas of fermions. In their paper published in the journal Science, the group describes their work with a 2D Fermi gas and what they learned from it.
NEW QUANTUM MATERIAL DISCOVERED
In everyday life, phase transitions usually have to do with temperature changes—for example, when an ice cube gets warmer and melts. But there are also different kinds of phase transitions, depending on other parameters such as magnetic field. In order to understand the quantum properties of materials, phase transitions are particularly interesting when they occur directly at the absolute zero point of temperature. These transitions are called “quantum phase transitions” or a “quantum critical points.”
GENERATING ELECTRICITY FROM HEAT USING A SPIN SEEBECK DEVICE
Thermoelectric (TE) conversion offers carbon-free power generation from geothermal, waste, body or solar heat, and shows promise to be the next-generation energy conversion technology. At the core of such TE conversion, there lies an all solid-state thermoelectric device which enables energy conversion without the emission of noise, vibrations, or pollutants. To this, a POSTECH research team proposed a way to design the next-generation thermoelectric device that exhibits remarkably simple manufacturing process and structure compared to the conventional ones, while displaying improved energy conversion efficiency using the spin Seebeck effect (SSE).

RESEARCHERS FIND GREENLAND GLACIAL MELTWATERS RICH IN MERCURY
New research shows that concentrations of the toxic element mercury in rivers and fjords connected to the Greenland Ice Sheet are comparable to rivers in industrial China, an unexpected finding that is raising questions about the effects of glacial melting in an area that is a major exporter of seafood.
SURGE IN NITROGEN HAS TURNED SARGASSUM INTO THE WORLD’S LARGEST HARMFUL ALGAL BLOOM
For centuries, pelagic Sargassum, floating brown seaweed, have grown in low nutrient waters of the North Atlantic Ocean, supported by natural nutrient sources like excretions from fishes and invertebrates, upwelling and nitrogen fixation. Using a unique historical baseline from the 1980s and comparing it to samples collected since 2010, researchers from Florida Atlantic University’s Harbor Branch Oceanographic Institute and collaborators have discovered dramatic changes in the chemistry and composition of Sargassum, transforming this vibrant living organism into a toxic “dead zone.”
SYNCHROTRON X-RAY EXPERIMENT REVEALS A SMALL NUDGE WITH BIG CONSEQUENCES
In a study published in the Nature Research journal Communications Materials, QUT researchers Dr. Christoph Schrank, Dr. Oliver Gaede, from the School of Earth and Atmospheric Sciences, and Master of Science graduate Katherine Gioseffi teamed up with the Australian Synchrotron and colleagues from the University of New South Wales and the University of Warsaw to study how gypsum dehydrates much faster under pressure.

CHINA’S MARS ROVER STARTS ROAMING THE RED PLANET
China’s Mars rover drove from its landing platform and began exploring the surface on Saturday, state-run Xinhua news agency said, making the country only the second nation to land and operate a rover on the Red Planet.
OBSERVATIONS SHED MORE LIGHT ON THE PROPERTIES OF PULSAR PSR J0740+6620
An international team of astronomers has carried out X-ray observations of a massive millisecond pulsar known as PSR J0740+6620. Results of the observational campaign, presented in a paper published May 14 on the arXiv pre-print repository, deliver important information regarding the properties of this pulsar.
MILKY WAY NOT UNUSUAL, ASTRONOMERS FIND
The first detailed cross-section of a galaxy broadly similar to the Milky Way, published today, reveals that our galaxy evolved gradually, instead of being the result of a violent mash-up. The finding throws the origin story of our home into doubt.

THE BIRTH OF A SUBNANOMETER-SIZED SOCCER BALL
Ever since the existence of molecules was proven and molecular reactions were predicted, humans have wanted to visually observe how such events proceed. Such observations of single-molecule reactions are highly important for the fundamental understanding of chemical sciences, which would aid in the development of novel catalysts, materials, or drugs, and help us decipher the complex biochemical processes. However, this was not possible for the longest time in modern chemistry, and so far the information of dynamical processes on the nanometer scale was obtained only from indirect methods because molecules were too small to be visualized.
RESEARCHERS FIRST SYNTHESIZE CONJOINED BISMACROCYCLE WITH ALL PHENYLENE UNITS
The research team led by Prof. Du Pingwu from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) first successfully synthesized an all-phenylene bismacrocycle (bis- means two) with Siamese-twin structure and used fullerene as guest molecules to assemble a peanut-shaped supramolecular complex. This study was published in Angewandte Chemie.
