Unilever to halve use of new plastic

Anglo-Dutch commercial giant Unilever said Monday it will cut its use of new plastic by half by 2025 as pressure grows on multinational companies to do more for the environment.

Speech recognition using artificial neural networks and artificial bee colony optimization

Over the past decade or so, advances in machine learning have paved the way for the development of increasingly advanced speech recognition tools. By analyzing audio files of human speech, these tools can learn to identify words and phrases in different languages, converting them into a machine-readable format.

Scientists have identified the presence of cancer-suppressing cells in pancreatic cancer

A research team led by Nagoya University has revealed that cells containing a protein called Meflin have a role in restraining the progression of pancreatic cancer, a type of cancer that is hard to treat with traditional anti-cancer drugs. The team has also shown that cancer progression can be limited by artificially increasing the amount of this protein in the cells. These findings could lead to the development of new therapies against pancreatic cancer. This study was published online in Cancer Research on Aug 22, 2019.

Partnership plans to produce Mo-99 to fill global demand for medical applications

SHINE Medical Technologies and partner Phoenix LLC have developed a new way to produce molybdenum-99 (Mo-99) for use in medical applications. They claim that testing has shown their new technology breaks the world record for the strongest nuclear fusion reactor in a steady-state system.

Novel AI chip design platform to give the semiconductor industry a boost in productivity and quality

A*STAR researchers have developed an AI chip design platform that has the potential to transform the multibillion-dollar global integrated circuit (IC) design industry by accelerating design optimisation, reducing IC design turnaround time, and improving productivity significantly by twofold.

Microscope prints patterns at the nanoscale

Researchers from AMOLF's 3-D-Photovoltaics group have used an atomic force microscope to electrochemically print at the nanoscale. This technique can print structures for a new generation of solar cells on chips. The researchers published their results today in the online journal Nanoscale.

A symbiotic boost for greenhouse tomato plants

Use of saline water to irrigate crops would bolster food security for many arid countries; however, this has not been possible due to the detrimental effects of salt on plants. Now, researchers at KAUST, along with scientists in Egypt, have shown that saline irrigation of tomato is possible with the help of a beneficial desert root fungus. This represents a new key technology for countries lacking water resources.

Trio win Nobel Medicine Prize for work on cells, oxygen

US researchers William Kaelin and Gregg Semenza and Britain's Peter Ratcliffe on Monday shared the Nobel Medicine Prize for discoveries on how cells sense and adapt to oxygen availability, the Nobel Assembly said.

More energy means more effects—in proton collisions

The higher the collision energy of particles, the more interesting the physics. Scientists from the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow have found further confirmation of this assumption, this time, in the high energy collision of protons with protons or lead nuclei.
