research meaning english

English dominates scientific research – here’s how we can fix it, and why it matters

It is often remarked that Spanish should be more widely spoken or understood in the scientific community given its number of speakers around the world, a figure the Instituto Cervantes places at almost 600 million .

However, millions of speakers do not necessarily grant a language strength in academia. This has to be cultivated on a scientific, political and cultural level, with sustained efforts from many institutions and specialists.

The scientific community should communicate in as many languages as possible

By some estimates, as much as 98% of the world’s scientific research is published in English , while only around 18% of the world’s population speaks it. This makes it essential to publish in other languages if we are to bring scientific research to society at large.

The value of multilingualism in science has been highlighted by numerous high profile organisations, with public declarations and statements on the matter from the European Charter for Researchers , the Helsinki Initiative on Multiligualism , the Unesco Recommendation on Open Science , the OPERAS Multiligualism White Paper , the Latin American Forum on Research Assessment , the COARA Agreement on Reforming Research Assessment , and the Declaration of the 5th Meeting of Minsters and Scientific Authorities of Ibero-American Countries . These organisations all agree on one thing: all languages have value in scientific communication.

As the last of these declarations points out, locally, regionally and nationally relevant research is constantly being published in languages other than English. This research has an economic, social and cultural impact on its surrounding environment, as when scientific knowledge is disseminated it filters through to non-academic professionals, thus creating a broader culture of knowledge sharing.

Greater diversity also enables fluid dialogue among academics who share the same language, or who speak and understand multiple languages. In Ibero-America, for example, Spanish and Portuguese can often be mutually understood by non-native speakers, allowing them to share the scientific stage. The same happens in Spain with the majority of its co-official languages .

No hierarchies, no categories

Too often, scientific research in any language other than English is automatically seen as second tier, with little consideration for the quality of the work itself.

This harmful prejudice ignores the work of those involved, especially in the humanities and social sciences. It also profoundly undermines the global academic community’s ability to share knowledge with society.

By defending and preserving multilingualism, the scientific community brings research closer to those who need it. Failing to pursue this aim means that academia cannot develop or expand its audience. We have to work carefully, systematically and consistently in every language available to us.

The logistics of strengthening linguistic diversity in science

Making a language stronger in academia is a complex process. It does not happen spontaneously, and requires careful coordination and planning. Efforts have to come from public and private institutions, the media, and other cultural outlets, as well as from politicians, science diplomacy , and researchers themselves.

Many of these elements have to work in harmony, as demonstrated by the Spanish National Research Council’s work in ES CIENCIA , a project which seeks to unite scientific and and political efforts.

Academic publishing and AI models: a new challenge

The global academic environment is changing as a result the digital transition and new models of open access. Research into publishers of scientific content in other languages will be essential to understanding this shift. One thing is clear though: making scientific content produced in a particular language visible and searchable online is crucial to ensuring its strength.

In the case of academic books, the transition to open access has barely begun , especially in the commercial publishing sector, which releases around 80% of scientific books in Spain. As with online publishing, a clear understanding will make it possible to design policies and models that account for the different ways of disseminating scientific research, including those that communicate locally and in other languages. Greater linguistic diversity in book publishing can also allow us to properly recognise the work done by publishers in sharing research among non-English speakers.

Read more: Removing author fees can help open access journals make research available to everyone

Making publications, datasets, and other non-linguistic research results easy to find is another vital element, which requires both scientific and technical support. The same applies to expanding the corpus of scientific literature in Spanish and other languages, especially since this feeds into generative artificial intelligence models.

If linguistically diverse scientific content is not incorporated into AI systems, they will spread information that is incomplete, biased or misleading: a recent Spanish government report on the state of Spanish and co-official languages points out that 90% of the text currently fed into AI is written in English.

Deep study of terminology is essential

Research into terminology is of the utmost importance in preventing the use of improvised, imprecise language or unintelligible jargon. It can also bring huge benefits for the quality of both human and machine translations, specialised language teaching, and the indexing and organisation of large volumes of documents.

Terminology work in Spanish is being carried out today thanks to the processing of large language corpuses by AI and researchers in the TeresIA project, a joint effort coordinated by the Spanish National Research Council. However, 15 years of ups and downs were needed to to get such a project off the ground in Spanish.

The Basque Country, Catalonia and Galicia, on the other hand, have worked intensively and systematically on their respective languages. They have not only tackled terminology as a public language policy issue, but have also been committed to established terminology projects for a long time.

Multiligualism is a global issue

This need for broader diversity also applies to Ibero-America as a whole, where efforts are being coordinated to promote Spanish and Portuguese in academia, notably by the Ibero-American General Secretariat and the Mexican National Council of Humanities, Sciences and Technologies .

While this is sorely needed, we cannot promote the region’s two most widely spoken languages and also ignore its diversity of indigenous and co-official languages. These are also involved in the production of knowledge, and are a vehicle for the transfer of scientific information, as demonstrated by efforts in Spain.

Each country has its own unique role to play in promoting greater linguistic diversity in scientific communication. If this can be achieved, the strength of Iberian languages – and all languages, for that matter – in academia will not be at the mercy of well intentioned but sporadic efforts. It will, instead, be the result of the scientific community’s commitment to a culture of knowledge sharing.

Mustafa Suleyman, DeepMind and Inflection Co-founder, joins Microsoft to lead Copilot

Mar 19, 2024 | Microsoft Corporate Blogs

  • Share on Facebook (opens new window)
  • Share on Twitter (opens new window)
  • Share on LinkedIn (opens new window)

Satya Nadella, Chief Executive Officer, shared the below communication today with Microsoft employees.

I want to share an exciting and important organizational update today. We are in Year 2 of the AI platform shift and must ensure we have the capability and capacity to boldly innovate.

There is no franchise value in our industry and the work and product innovation we drive at this moment will define the next decade and beyond. Let us use this opportunity to build world-class AI products, like Copilot, that are loved by end-users! This is about science, engineering, product, and design coming together and embracing a learning mindset to push our innovation culture and product building process forward in fundamental ways.

In that context, I’m very excited to announce that Mustafa Suleyman and Karén Simonyan are joining Microsoft to form a new organization called Microsoft AI, focused on advancing Copilot and our other consumer AI products and research.

Mustafa will be EVP and CEO, Microsoft AI, and joins the senior leadership team (SLT), reporting to me. Karén is joining this group as Chief Scientist, reporting to Mustafa. I’ve known Mustafa for several years and have greatly admired him as a founder of both DeepMind and Inflection, and as a visionary, product maker, and builder of pioneering teams that go after bold missions.

Karén, a Co-founder and Chief Scientist of Inflection, is a renowned AI researcher and thought leader, who has led the development of some of the biggest AI breakthroughs over the past decade including AlphaZero.

Several members of the Inflection team have chosen to join Mustafa and Karén at Microsoft. They include some of the most accomplished AI engineers, researchers, and builders in the world. They have designed, led, launched, and co-authored many of the most important contributions in advancing AI over the last five years. I am excited for them to contribute their knowledge, talent, and expertise to our consumer AI research and product making.

At our core, we have always been a platform and partner-led company, and we’ll continue to bring that sensibility to all we do. Our AI innovation continues to build on our most strategic and important partnership with OpenAI. We will continue to build AI infrastructure inclusive of custom systems and silicon work in support of OpenAI’s foundation model roadmap, and also innovate and build products on top of their foundation models. And today’s announcement further reinforces our partnership construct and principles.

As part of this transition, Mikhail Parakhin and his entire team, including Copilot, Bing, and Edge; and Misha Bilenko and the GenAI team will move to report to Mustafa. These teams are at the vanguard of innovation at Microsoft, bringing a new entrant energy and ethos, to a changing consumer product landscape driven by the AI platform shift. These organizational changes will help us double down on this innovation.

Kevin Scott continues as CTO and EVP of AI, responsible for all-up AI strategy, including all system architecture decisions, partnerships, and cross-company orchestration. Kevin was the first person I leaned on to help us manage our transformation to an AI-first company and I’ll continue to lean on him to ensure that our AI strategy and initiatives are coherent across the breadth of Microsoft.

Rajesh Jha continues as EVP of Experiences & Devices and I’m grateful for his leadership as he continues to build out Copilot for Microsoft 365, partnering closely with Mustafa and team.

There are no other changes to the senior leadership team or other organizations.

We have been operating with speed and intensity and this infusion of new talent will enable us to accelerate our pace yet again.

We have a real shot to build technology that was once thought impossible and that lives up to our mission to ensure the benefits of AI reach every person and organization on the planet, safely and responsibly. I’m looking forward to doing so with you.

The Effects of Climate Change

The effects of human-caused global warming are happening now, are irreversible for people alive today, and will worsen as long as humans add greenhouse gases to the atmosphere.

research meaning english

  • We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves.
  • Scientists predict global temperature increases from human-made greenhouse gases will continue. Severe weather damage will also increase and intensify.

Earth Will Continue to Warm and the Effects Will Be Profound

Effects_page_triptych

Global climate change is not a future problem. Changes to Earth’s climate driven by increased human emissions of heat-trapping greenhouse gases are already having widespread effects on the environment: glaciers and ice sheets are shrinking, river and lake ice is breaking up earlier, plant and animal geographic ranges are shifting, and plants and trees are blooming sooner.

Effects that scientists had long predicted would result from global climate change are now occurring, such as sea ice loss, accelerated sea level rise, and longer, more intense heat waves.

The magnitude and rate of climate change and associated risks depend strongly on near-term mitigation and adaptation actions, and projected adverse impacts and related losses and damages escalate with every increment of global warming.

research meaning english

Intergovernmental Panel on Climate Change

Some changes (such as droughts, wildfires, and extreme rainfall) are happening faster than scientists previously assessed. In fact, according to the Intergovernmental Panel on Climate Change (IPCC) — the United Nations body established to assess the science related to climate change — modern humans have never before seen the observed changes in our global climate, and some of these changes are irreversible over the next hundreds to thousands of years.

Scientists have high confidence that global temperatures will continue to rise for many decades, mainly due to greenhouse gases produced by human activities.

The IPCC’s Sixth Assessment report, published in 2021, found that human emissions of heat-trapping gases have already warmed the climate by nearly 2 degrees Fahrenheit (1.1 degrees Celsius) since 1850-1900. 1 The global average temperature is expected to reach or exceed 1.5 degrees C (about 3 degrees F) within the next few decades. These changes will affect all regions of Earth.

The severity of effects caused by climate change will depend on the path of future human activities. More greenhouse gas emissions will lead to more climate extremes and widespread damaging effects across our planet. However, those future effects depend on the total amount of carbon dioxide we emit. So, if we can reduce emissions, we may avoid some of the worst effects.

The scientific evidence is unequivocal: climate change is a threat to human wellbeing and the health of the planet. Any further delay in concerted global action will miss the brief, rapidly closing window to secure a liveable future.

Here are some of the expected effects of global climate change on the United States, according to the Third and Fourth National Climate Assessment Reports:

Future effects of global climate change in the United States:

sea level rise

U.S. Sea Level Likely to Rise 1 to 6.6 Feet by 2100

Global sea level has risen about 8 inches (0.2 meters) since reliable record-keeping began in 1880. By 2100, scientists project that it will rise at least another foot (0.3 meters), but possibly as high as 6.6 feet (2 meters) in a high-emissions scenario. Sea level is rising because of added water from melting land ice and the expansion of seawater as it warms. Image credit: Creative Commons Attribution-Share Alike 4.0

More Droughts and Heat Waves

Droughts in the Southwest and heat waves (periods of abnormally hot weather lasting days to weeks) are projected to become more intense, and cold waves less intense and less frequent. Image credit: NOAA

2013 Rim Fire

Longer Wildfire Season

Warming temperatures have extended and intensified wildfire season in the West, where long-term drought in the region has heightened the risk of fires. Scientists estimate that human-caused climate change has already doubled the area of forest burned in recent decades. By around 2050, the amount of land consumed by wildfires in Western states is projected to further increase by two to six times. Even in traditionally rainy regions like the Southeast, wildfires are projected to increase by about 30%.

Changes in Precipitation Patterns

Climate change is having an uneven effect on precipitation (rain and snow) in the United States, with some locations experiencing increased precipitation and flooding, while others suffer from drought. On average, more winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century. Image credit: Marvin Nauman/FEMA

Frost-Free Season (and Growing Season) will Lengthen

The length of the frost-free season, and the corresponding growing season, has been increasing since the 1980s, with the largest increases occurring in the western United States. Across the United States, the growing season is projected to continue to lengthen, which will affect ecosystems and agriculture.

Arctic Is Very Likely to Become Ice-Free

Sea ice cover in the Arctic Ocean is expected to continue decreasing, and the Arctic Ocean will very likely become essentially ice-free in late summer if current projections hold. This change is expected to occur before mid-century.

U.S. Regional Effects

Climate change is bringing different types of challenges to each region of the country. Some of the current and future impacts are summarized below. These findings are from the Third 3 and Fourth 4 National Climate Assessment Reports, released by the U.S. Global Change Research Program .

  • Northeast. Heat waves, heavy downpours, and sea level rise pose increasing challenges to many aspects of life in the Northeast. Infrastructure, agriculture, fisheries, and ecosystems will be increasingly compromised. Farmers can explore new crop options, but these adaptations are not cost- or risk-free. Moreover, adaptive capacity , which varies throughout the region, could be overwhelmed by a changing climate. Many states and cities are beginning to incorporate climate change into their planning.
  • Northwest. Changes in the timing of peak flows in rivers and streams are reducing water supplies and worsening competing demands for water. Sea level rise, erosion, flooding, risks to infrastructure, and increasing ocean acidity pose major threats. Increasing wildfire incidence and severity, heat waves, insect outbreaks, and tree diseases are causing widespread forest die-off.
  • Southeast. Sea level rise poses widespread and continuing threats to the region’s economy and environment. Extreme heat will affect health, energy, agriculture, and more. Decreased water availability will have economic and environmental impacts.
  • Midwest. Extreme heat, heavy downpours, and flooding will affect infrastructure, health, agriculture, forestry, transportation, air and water quality, and more. Climate change will also worsen a range of risks to the Great Lakes.
  • Southwest. Climate change has caused increased heat, drought, and insect outbreaks. In turn, these changes have made wildfires more numerous and severe. The warming climate has also caused a decline in water supplies, reduced agricultural yields, and triggered heat-related health impacts in cities. In coastal areas, flooding and erosion are additional concerns.

What’s the difference between climate change and global warming?

“Global warming” refers to the long-term warming of the planet. “Climate change” encompasses global warming, but refers to the broader range of changes that are happening to our planet, including rising sea levels; shrinking mountain glaciers; accelerating ice melt in Greenland, Antarctica and the Arctic; and shifts in flower/plant blooming times.

Is it too late to prevent climate change?

Humans have caused major climate changes to happen already, and we have set in motion more changes still. However, if we stopped emitting greenhouse gases today, the rise in global temperatures would begin to flatten within a few years. Temperatures would then plateau but remain well-elevated for many, many centuries.
