Build the technology of the future. Protect the nation from attack. Buy a sports car.

These were some of the rewards of working in the semiconductor industry, 200 high school students learned at a recent daylong recruiting event for one of Taiwan’s top engineering schools.

“Taiwan doesn’t have many natural resources,” Morris Ker, the chair of the newly created microelectronics department at National Yang Ming Chiao Tung University told the students. “You are Taiwan’s high-quality ‘brain mine.’ You must not waste the intelligence given to you.”

The island of 23 million people produces nearly one-fifth of the world’s semiconductors, microchips that power just about everything—home appliances, cars, smartphones and more. Furthermore, Taiwan specializes in the smallest, most advanced processors, accounting for 69% of global production in 2022, according to the Semiconductor Industry Assn. and the Boston Consulting Group.

But a pandemic-induced chip shortage, along with rising geopolitical tensions in Asia, have highlighted the fragility of the current supply chain—and its reliance on an island under the specter of a takeover by China.

Across the U.S., Japan, South Korea, Taiwan and China, the semiconductor industry is already short hundreds of thousands of workers. In 2022, the consulting and financial services giant Deloitte estimated that semiconductor companies would need more than 1 million additional skilled workers by 2030.

Seeking to maintain Taiwan’s status as the chip-making capital of the world, the government and several corporations here helped the university—known as NYCU—create the microelectronics department last year to fast-track students into industry jobs. Now the department was recruiting its inaugural class.

Wu Min-han, 20, who sat front row with his mother, didn’t need much convincing.

He had first applied to college to major in mathematics, but dropped out after he lost interest in the subject. Then he read about the new microelectronics program and decided to apply. He’s waiting to hear.

“This department could have a pretty positive impact on my future career prospects,” he said.

Others were torn.

Lian Yu-yan, 18, said that while the new department seems impressive, she’s also interested in majoring in mechanical engineering and photonics. She hopes to find a high-paid tech job after graduating from college, but wants to keep her options open.

Her father, who accompanied her to the event, has worked in the semiconductor industry and sees high growth potential with the evolution of AI. However, that hasn’t done much to persuade his daughter.

“You can’t control Gen Z,” he said with a laugh and a shrug.

Many prospective students competing for the 65 slots in next semester’s program listed salary and job stability among their top considerations. In Taiwan, there are few industries that can compete with semiconductors on pay and prestige.

As the rise of electric vehicles, artificial intelligence and other advanced technologies demand more semiconductors, many nations are making chip self-sufficiency a top priority.

In the U.S., Europe and Asia, governments have announced more than $316 billion in tax incentives for the semiconductor industry since 2021, according to Semiconductor Industry Assn. and the Boston Consulting Group.

A May report by those organizations projected that private companies will spend an additional $2.3 trillion through 2032 to build more facilities that make semiconductors, also known as fabrication plants, or fabs.

Meanwhile, the expansion of chip-making capabilities is exacerbating another shortage: in the people trained to make them.

As the global battle for talent heats up and Taiwan loses manufacturing market share, the island has even more incentive to cultivate its next generation of workers.

Known as Taiwan’s “silicon shield,” the semiconductor industry is considered so critical to the global economy that it could deter Beijing, which lays claim to the island democracy, from launching a military assault. Taiwanese often refer to Taiwan Semiconductor Manufacturing Company, the world’s largest chipmaker and a major Apple supplier, as the “sacred mountain protecting the nation.”

In his presentation, Ker gave another example of the industry’s indispensability. When Taiwan’s worst earthquake in a quarter-century hit in April, factory workers were evacuated but quickly returned—a sign, Ker said, of the manufacturing hub’s resilience.

But to Su Xin-zheng, a second-year engineering student at NYCU, the natural disaster response was representative of the drudgery required to keep churning out so many of the world’s chips.

“People are always on call,” said Su, who added that he would prioritize having leisure time over a hefty salary. “We saw that they all went back in to protect the machines.”

Industry veterans evoke brutal hours and sacrifice when they describe how Taiwan built its semiconductor industry from the ground up. With black humor they speak, metaphorically, of ruining their livers by working through the night.

They fear that the younger generation is less inclined to such punishing work.

In particular, the growing emphasis on work-life balance is eroding interest in jobs at the fabrication plants that Taiwan and TSMC are known for.

For the past two years, labor demand in manufacturing has exceeded that of other parts of the chip-making process, such as designing the circuit boards or packaging them after they are made, according to the local recruitment platform 104 Job Bank. Engineering students enrolled at NYCU said such jobs seemed draining, with lower pay than research or design positions.

Ting Cheng-wei, 23, frequents anonymous online forums to learn more about the salaries and job descriptions at different companies. That’s how he knows that manufacturing positions, which require full-body suits to guard against contamination and 12-hour shifts on two-day rotations, don’t appeal to him.

“Working in the fab seems like working as a laborer,” said Ting, a master’s student and teaching assistant at the university. “Why would I work at a fab when I can sit in an office with higher pay?”

He speculated that job shortages at semiconductor plants could be solved by simply offering more money.

That would be enough for 19-year-old Wei Yu-han, who was ambivalent about semiconductors after her first year studying mechanical engineering. After visiting a fab on a school trip, she thought the work seemed straightforward and well-paid.

“I probably just brainwashed myself into liking it,” she said. “I can give up my freedom for money.”

At the end of the introductory seminar, all students in attendance took a short entrance exam as part of their applications. Still, enrollment in the new department is restricted by another squeeze on human resources—Ker added that the school is desperately looking to hire more semiconductor teachers as well.

No traction for more positive economic developments

Say “inflation” these days and the minds of most Americans jump to steep grocery bills and high interest rates.

As highlighted by two recent papers by Stefanie Stantcheva, the Nathaniel Ropes Professor of Political Economy, the majority are much less likely to focus on the more positive economic trends of the past few years, including wage growth and strong employment prospects.

What’s more, Americans overwhelmingly oppose the tools that policymakers use to mitigate inflation‘s worst effects. In fact, many see inflation as only getting worse when the Federal Reserve raises interest rates, as it did 11 times between spring 2022 and last summer.

“There hasn’t been enough work to see how people understand inflation, what policies they want to support in order to fight inflation, and also how inflation actually impacts them,” Stantcheva said.

For a paper titled “People’s Understanding of Inflation,” Stantcheva and graduate student co-authors Francesco Nuzzi (Harvard) and Alberto Binetti (Princeton) conducted a large-scale survey through which they found that most Americans believe inflation has been caused by government action, trailed by supply-chain disruptions and other COVID-related issues. Respondents expressed skepticism about rate hikes as an effective countermeasure.

Clear partisan differences surfaced in the findings. Republicans were more likely to blame inflation on the government (more than 75% of GOP voters vs. 60% of Democrats) and less likely to blame private companies.

All respondents saw inflation as more harmful to lower-income people, but Republicans were less likely to support policies that might help these households, such as expanding access to food stamps (supported by 80% of Democrats vs. 50% of Republicans) or boosting the minimum wage (80% for Democrats vs. 50% of Republicans).

The most cited burden of inflation was the impact on family budgets, notably the way it raises the stakes on household purchases and standard of living.

Among the details that caught Nuzzi’s attention was the lack of ambiguity in survey responses. “People perceive inflation as unequivocally negative, rarely associating it with positive economic developments or with a good economy,” he said.

Discussing the second paper, “Why Do We Dislike Inflation?” Stantcheva noted that inflation typically plays out in one of two ways. The first is a product of a booming economy. “There’s high demand, things are going well, and that can actually generate inflation.”

The other possibility, “stagflation,” is associated with high unemployment and stagnant demand.

Most respondents viewed all inflationary episodes as “stagflation,” Stantcheva said. “There is a perception that inflation is unambiguously a bad thing.”

Views on the tools policymakers use in attempts to control inflation echoed findings from “People’s Understanding of Inflation.”

“People tend to think that policymakers do not face harsh trade-offs when it comes to fighting inflation,” she said.

This is important, she added, because “when you ask people what type of policies they support to fight inflation … contractionary monetary policies like increasing interest rates or reducing money supply have very low support.”

EU targets UAE telecoms firm in new anti-subsidy probe


Telecoms group e& signed an agreement in August 2023 to purchase EU telecoms assets
Telecoms group e& signed an agreement in August 2023 to purchase EU telecoms assets.

The European Union on Monday announced a formal anti-subsidy probe targeting an Emirati telecoms company, the first action under new rules to focus on a foreign bid to buy EU assets.

Brussels has ramped up its scrutiny of foreign investment into the bloc in a bid to defend European industry, usually from rising threats from China and the United States.

The latest probe is the first against a non-Chinese company under new EU rules.

Telecoms group e&, whose majority stakeholder is the United Arab Emirates government, signed a 2.15-billion-euro ($2.3-billion) agreement in August 2023 to purchase Czech PPF telecoms group’s assets in Bulgaria, Hungary, Serbia and Slovakia.

The European Commission said a preliminary probe “indicates that there are sufficient indications that e& has received foreign subsidies distorting the EU internal market”.

The alleged subsidies “notably take the form of an unlimited guarantee from the UAE and a loan from UAE-controlled banks directly facilitating the transaction”, it added.

The commission said it will investigate whether the subsidies lead to “actual or potential negative effects” on the bid’s process or the EU’s internal market.

It will specifically look at whether the “support” allowed the UAE company “to deter or outbid other parties interested in the acquisition”.

The probe was launched under new rules known as the Foreign Subsidies Regulation (FSR), which came into force last year and seek to prevent foreign subsidies from undermining fair competition in the EU.

“Today we open our first in-depth investigation into a concentration under the Foreign Subsidies Regulation, the EU’s competition commissioner, Margrethe Vestager, said.

“The FSR allows us to tackle distortive support from third countries for the acquisition of businesses in the EU,” she added in a statement.

The commission has until October 15, 2024, to take a decision.

Brussels has already flexed its legal muscle with the new rules, forcing Chinese companies to withdraw from certain projects.

Chinese rail giant CRRC exited a tendered project in Bulgaria in March after the EU launched a probe into it over suspected subsidies.

And a similar investigation saw two Chinese-owned solar panel manufacturers withdraw from a public procurement tender in Romania last month.

As long as humans have been traveling into space, astronauts have experienced significant health effects from the extreme conditions of space flight, notably the reduction of gravity.

Two Buck scientists led a team that has revealed for the first time how the lack of gravity affects the cells of the immune system at single cell resolution. The co-senior authors, along with Christopher E. Mason, Ph.D. of Weill Cornell Medical College, Associate Professor David Furman, Ph.D. and Associate Professor Daniel Winer, MD, have published an extensive survey of how gravity affects immune cells, and the identification of “space nutraceuticals” to counter aberrant effects of microgravity on these cells. The work is published in Nature Communications

“We show how simulated microgravity shapes immune cells and how the changes in force alter the cells’ function at the single cell level,” said Winer. “This level of resolution is new and exciting in understanding the effects of microgravity on cells.”

Using cells in simulated microgravity, combined with data from space flight from astronauts and mice on the International Space Station, the researchers created a complete picture of how the different cells of the immune system in the peripheral blood are shaped by reduced gravity. These cells include lymphocytes and monocytes, which are the main players in immunity.

The study has potential implications for immune aging on Earth since the changes observed during aging resemble those captured during space travel.

The team additionally outlines a pathway for identifying compounds that can reverse the effects of near zero gravity, and demonstrates that one of the compounds, quercetin, shows promise for mitigating the damage caused by spaceflight and during normal aging on the ground.

“Our work provides a resource to better understand how and why the immune system changes in simulated microgravity and spaceflight,” said Furman. “We also provide a way to develop countermeasures to maintain normal immunity under these harsh conditions.”

Astronauts in low Earth orbit, such as on the International Space Station, suffer from immune system problems, especially infections, latent viruses reactivating, and skin sensitivity. These reactions occur even on short-term spaceflights.

Previous studies using actual or simulated microgravity conditions have found impaired function of various immune cells. However, the fundamental mechanisms, genes, and pathways that explain immune dysfunction in microgravity were mostly unclear, the researchers said. They wanted to understand what was happening on a cellular level to explain the changes.

The team, led by the study’s co-first authors Buck postdoctoral researcher Fei Wu, Ph.D. and graduate student Huixun Du, examined in depth how 25 hours of simulated microgravity affects the human peripheral blood mononuclear immune system, using samples from 27 healthy human donors between the ages of 20 and 46.

To simulate an environment with almost no gravity, the team grew the cells inside of a Rotating Wall Vessel, a device developed by NASA to simulate microgravity conditions.

To explore the changes caused by reduced gravity, the team used a number of techniques, including sequencing and super-resolution microscopy.

They then validated their findings by comparing their data with other space studies done in humans and mice, including the JAXA (Cell-Free Epigenome study) mission, SpaceX’s Inspiration 4 mission, NASA’s Twins Study, and spleens from mice housed on the International Space Station.

“Interestingly, changes in mechanical forces appear to orchestrate immune cell function,” said Winer, whose interest in studying space medicine grew from him delving into the emerging field of mechanoimmunology, or how environmental forces affect immune cell function. Parts of astroimmunology are related to mechanoimmunology, but it is proving its own as a new field, he said, paving the way to better understand how to help the immune system survive in space.

After unearthing several genes and biochemical pathways that are affected by microgravity, the team wanted to see if they could find any specific drugs or supplements that could protect the immune cells. To help them search, they used machine learning technology developed by Furman at the Buck, which can detect more than 2 million interactions between genes and different drugs and foods.

They identified dozens of potential compounds and chose one, the plant pigment quercetin (often found in red onions, grapes, berries, apples and citrus fruits among others) to explore further since it is widely available as an antioxidant and anti-aging supplement. Quercetin turned out to reverse approximately 70 percent of the changes caused by lack of gravity and protected the cells from reactive oxygen species excess.

“These findings define hallmarks of immune cell alteration in simulated microgravity, with correlation to spaceflight exposures in mice and humans,” said Winer.

“This work helps define avenues for future research in mechanoimmunology and astroimmunology and provides opportunities to develop countermeasures to maintain normal cellular function in space.”

Furman adds that this publication sets the standard for how to analyze the physiological changes that accompany space travel. “This is the first comprehensive study that provides the scientific community worldwide with an atlas to understand human biology in this extreme condition,” he says.

“The implications are huge, beyond humans in space,” he adds. The researchers are excited to explore the parallel changes they are finding that occur in aging humans on the ground, and to use the knowledge to design interventions that can potentially reverse the immune dysfunction that accompanies aging.

The plants bees need to maintain a healthy diet have been revealed

As critical pollinators, bees keep our agricultural systems going—but human-caused changes to the planet heavily impact their foraging options. To help protect our food security, we need more information about bees’ own dietary requirements. Scientists writing in Frontiers in Sustainable Food Systems have studied the nutritional value of 57 types of pollen and found that bees need to forage from a variety of plants to balance their diet between fatty acids and essential amino acids.

“Despite public interest and a rise in pollinator plantings, little is known about which plant species are best suited for bee health,” said Dr. Sandra Rehan of York University, senior author. “This study aimed to better understand the nutritional value of plant species. Based on their ideal protein to lipid ratios for wild bee nutrition, we recommend that pollen species from roses, clovers, red raspberry, and tall buttercup should be emphasized in wildflower restoration projects.”

The bees’ needs

Pollen and bees are heavily interdependent: Plants need bees to spread their pollen to reproduce, and bees need pollen to eat. While bees get their carbohydrates from nectar, pollen provides proteins, lipids, and other critical nutrients. Anthropic changes to the environment which alter the availability and the properties of pollen risk malnourished bees.

Bees especially need to consume high-quality foods containing non-esterified fatty acids like omega-6 and omega-3. Without these nutrients, bees live shorter lives, have weaker immune systems, and are less able to cope with environmental stressors—but if bees consume them in the wrong ratio, they experience cognitive problems. Bees also need essential amino acids, which are necessary for cognitive health and reproduction—but if they eat too much, they may be more susceptible to certain parasites.

To understand which plants are best for bees, the scientists collected pollen samples from 57 species found in North America, either from fresh flowers in the wild or from flowers dried in the lab. They chose the plant species based on their importance to species of wild northeastern bee and their prevalence. The pollen was processed and analyzed for levels of different amino acids, non-esterified fatty acids, and protein to lipid and omega-6:3 ratios, to determine which plants were best for bees.

The scientists also investigated whether closely related species of plant provided similar nutritional benefits, and whether species that had been introduced to the area where they were collected were less nutritious than endemic species.

Healthy eating habits

In general, plants from the same family offered bees quite different nutrients, with the exception of essential amino acids. Plants from the cabbage family, the legume family, and the daisy family all had similar levels of essential amino acids compared to other plants within the same family. Daisies, a very important plant for foraging bees, boasted particularly high levels of essential amino acids. Interestingly, plants that were high in essential amino acids were relatively low in non-esterified fatty acids, and vice versa.

“There is a potential tradeoff between fatty acid and amino acid content within pollen, suggesting that a diverse floral diet may benefit bees more than a single pollen source,” said Rehan. “No one plant species is optimal for generalized wild bee health.”

The scientists’ results indicated that feeding from many different flowers is best for most bees, and that feeding from endemic species of plant offers no nutritional advantage. Most pollen species contain most of the necessary nutrients, but to get the optimal levels of nutrients in their diets, bees would need to forage from several different plant species. The scientists suggested that this diversity of nutritional content reflects the diverse needs of different species of bees, especially the specialist species that favor particular plants. A wide variety of sources of nutrition with different properties means that all bees can forage on the plants that feed them best.

“We hope this work will help inform flowering plant selections for pollinator gardens,” said Rehan. “But here we examined only 57 plant species, and there are thousands to examine to understand nutritional profiles. We hope this will inspire future similar research as well as follow-up studies on the preference and survival of bees on different diets.”
