Deforestation across the ‘Maritime Continent’ is making El Niño-Southern Oscillation more unpredictable, finds study

Posted by in category: climatology

El Niño-Southern Oscillation (ENSO) is a climate phenomenon occurring every 2–7 years in the tropical Pacific Ocean, associated with changes in air pressure east to west.

During El Niño events equatorial blowing west weaken, causing changes in air pressure and that move warm surface water eastward from the western Pacific to coastal South America. This results in a deeper thermocline (the depth at which rapidly changes) that prevents the normal upwelling of cooler, nutrient-rich waters, having devastating impacts on marine food chains, as well as local communities reliant upon the fishing industry.

It also brings heavier and prolonged rainfall to South America, increasing the threat of flooding, while in Australia and Indonesia there is drought, posing hazards for water supply and irrigation for agriculture. During La Niña events, all off these conditions reverse.

Machine learning gives users ‘superhuman’ ability to open and control tools in virtual reality

Posted by in categories: robotics/AI, transportation, virtual reality

Researchers have developed a virtual reality application where a range of 3D modeling tools can be opened and controlled using just the movement of a user’s hand.

The researchers, from the University of Cambridge, used machine learning to develop ‘HotGestures’—analogous to the hot keys used in many desktop applications.

HotGestures give users the ability to build figures and shapes in without ever having to interact with a menu, helping them stay focused on a task without breaking their train of thought.

Increasing ocean wave energy observed in Earth’s seismic wavefield since the late 20th century

Posted by in category: energy

Ocean waves induce geographically extensive seafloor forces that excite a continuous and globally detectable seismic wavefield. This study infers global near-coastal average wave energy intensification at a rate of 0.27% per year since the late 1980’s, and 0.35% per year since January 2000.

Nuclear weapons are illegal at last

Posted by in categories: geopolitics, law, military, treaties

Nuclear arms are the most destructive, indiscriminate and monstrous weapons ever produced – but today, we can all celebrate a major milestone in the long march towards peace: the Treaty on the Prohibition of Nuclear Weapons (TPNW) is now part of international law!

The year 2021 also marks the 50th anniversary of Greenpeace, which began life in September 1971 when a small group of activists set sail to the island of Amchitka, off the west coast of Alaska, to try and stop nuclear weapons testing from taking place. Greenpeace could not be more delighted that in the anniversary year of our founding journey, we can join the celebration to mark this historic Treaty coming into force and pay our deepest respects to advocates for this momentous achievement, led by the International Campaign to Abolish Nuclear Weapons (ICAN).

Greenpeace France interviewed Jean-Marie Collin of ICAN France about the challenges and prospects that arise from the Treaty’s entry into force.

Nuclear Disarmament and UN Reforms

Posted by in categories: ethics, existential risks, geopolitics, military, nuclear weapons, policy, treaties

Although essentially the United Nations are now making nuclear weapons illegal with new treaties like nuclear disarmament. Russia currently has taken another route for globalization and possibly nuclear escalation. As currently the doomsday clock seems closer to midnight which could mean the end of the world scenarios due to Russias escalation and the possibility of all out nuclear war globally and then nuclear annihilation of the planet. Even with current wars are actually seemingly always going on but this global escalation of nuclear war is a zero sum game as no one would be the winner due to radiation levels circulating the planet. I do think that the us and china are in a treaty but so far Russia is still escalating which now holds the world now ransom.


This is a summary of Policy Brief 139 which is available with full references on the Toda Peace Institute’s website.

In January 2021, a global treaty came into force outlawing the bomb. The Treaty on the Prohibition of Nuclear Weapons (TPNW or Ban Treaty) is the most significant multilateral development in nuclear arms control since the Non-Proliferation Treaty’s (NPT) entry into force in 1970. It establishes a new normative settling point on the ethics, legality and legitimacy of the bomb.

PET scans may predict Parkinson’s disease and Lewy body dementia in at-risk individuals

Posted by in categories: biotech/medical, health, neuroscience

In a small study, researchers at the National Institutes of Health have found that positron emission tomography (PET) scans of the heart may identify people who will go on to develop Parkinson’s disease or Lewy body dementia among those at-risk for these diseases.

The findings, published in the Journal of Clinical Investigation and led by scientists at the National Institute of Neurological Disorders and Stroke (NINDS), part of NIH, may advance efforts to detect the earliest changes that years later lead to Parkinson’s disease and Lewy body dementia.

In 34 people with Parkinson’s disease risk factors, researchers conducted PET scans of the heart to gain insight into levels of the neurotransmitter norepinephrine. They found that the scans could distinguish individuals who would later be diagnosed with Parkinson’s or Lewy body dementia—both are brain diseases caused by abnormal deposits of the protein alpha-synuclein that form clumps known as Lewy bodies. The research was conducted at the NIH Clinical Center, currently the only location for 18 F-dopamine PET scanning.

Lung cancer researchers identify specific genetic change that predicts whether patients can respond to targeted therapy

Posted by in categories: biotech/medical, genetics

Squamous cell lung cancer is a lung cancer subtype that is particularly difficult to treat. A new study now has revealed a novel genetic alteration that occurs in some cases in this type of tumor and that may expose a weakness of the tumor for therapeutic intervention.

The University of Cologne researchers led by Professor Roman Thomas, director of the Department of Translational Genomics, was able to show that a certain genetic change occurs during tumor formation and that a previously unknown oncogene is produced. Oncogenes are genes that promote the growth of tumors. In some cases, they can be inhibited by targeted drug treatments.

This approach is often accompanied by a higher success rate and lower side effects compared to conventional chemotherapy. The scientists’ discovery could therefore be a first step toward a more successful therapy of this particular type of cancer.

An AI just negotiated a contract for the first time ever — and no human was involved

Posted by in categories: information science, law, robotics/AI

In a world first, artificial intelligence demonstrated the ability to negotiate a contract autonomously with another artificial intelligence without any human involvement.

British AI firm Luminance developed an AI system based on its own proprietary large language model (LLM) to automatically analyze and make changes to contracts. LLMs are a type of AI algorithm that can achieve general-purpose language processing and generation.

Jaeger Glucina, chief of staff and managing director of Luminance, said the company’s new AI aimed to eliminate much of the paperwork that lawyers typically need to complete on a day-to-day basis.
