Dam construction has resulted in widely fluctuating river flow in the Mekong, threatening fish productivity, which is key to the region’s economy.
Large dams on the Mekong River in China’s Yunnan Province have considerable impacts on downstream river flows, new research by myself and colleagues at Aalto University in Finland and published recently in the Journal of Hydropower has shown.
The Mekong originates in China where it is known as the Lancang, before flowing through Thailand, Laos, Cambodia and Vietnam. China has built a cascade of six hydropower dam projects on the upper reaches of the Mekong River.
The first project, known as Manwan, (1,670 MW) became operational in 1993 and the latest, known as Nuozhadu, (5,850 MW) began operations in 2014. The cascade has the capacity to produce 15,000 MW of power and store over 23 square kilometres of water, 28 per cent of the annual river flow at the border of China and Thailand.
Downstream countries are also exploiting their hydropower resources – with Laos recently announcing it will start construction of a third contentious dam on the Mekong.
We found that major changes to the river flow began in 2011 and were the largest in 2014. Hydropower operations caused exceptionally high dry season flows and low wet season flows in northern Thailand.
In 2014 the dry season flows reached record highs of two to three times the long-term average. During the same year, wet season flows reached record low levels and were roughly two thirds of the long-term average.
These changes in flow were observed over 2000 km downstream in Cambodia, where the 2014 dry season flows increased by half.
New Evidence of Dam Impacts
In 2012, we used simulation models to predict how the hydropower cascade would change river flow, and in fact our predictions closely matched the observed fluctuations in flow.
Thus we have a fairly good understanding of the changes taking place. It is now clear that the construction of large dams on the upper reaches of the Mekong have resulted in widely fluctuating river flow, depending on the hydropower operations.
Changes in river flow play an important role in the ecology and economy of the Mekong River, which is rich in biodiversity and the source of livelihoods and food security for millions of people.
Fishing is particularly important to the people as the Mekong River is one of the world’s most productive inland fisheries, with an annual catch of 2.6 million tonnes.
The annual value of the river’s fisheries is estimated to be USD 3.9-7 billion. Over 1,000 fish species have been found in the Mekong, including giant sting ray, freshwater dolphin and giant catfish.
A key driver of the biodiversity and productivity of the Mekong River is the river flow regime driven by monsoon rains, often called the annual flood pulse.
The flood pulse transports large amounts of sediment and nutrients along the river and has created diverse floodplain habitats. As the river flow changes, we have observed an increased variability of this flow regime and a smaller annual pulse. In addition, the dams block nutrient-rich sediment that would otherwise be carried downstream.
Our research predicts that these changes are likely to lead to lowered ecosystem productivity, which may have significant impacts on the ecosystems and communities that depend on the Mekong.
Reports by Chinese scientists have already shown the negative effect of dams on the ecology along the Chinese part of Mekong River and a reduction in number of fish species during the construction period of the six dam cascade.
The effects on the ecology and people in the downstream countries since the completion of the dams are yet to be scientifically documented and published.

Google’s Search Dominance Is Unwinding, But Still Accounting 48% Search Revenue
Google is so closely associated with its key product that its name is a verb that signifies “search.” However, Google’s dominance in that sector is dwindling.
According to eMarketer, Google will lose control of the US search industry for the first time in decades next year.
Google will remain the dominant search player, accounting for 48% of American search advertising revenue. And, remarkably, Google is still increasing its sales in the field, despite being the dominating player in search since the early days of the George W. Bush administration. However, Amazon is growing at a quicker rate.
Google’s Search Dominance Is Unwinding
Amazon will hold over a quarter of US search ad dollars next year, rising to 27% by 2026, while Google will fall even more, according to eMarketer.
The Wall Street Journal was first to report on the forecast.
Lest you think you’ll have to switch to Bing or Yahoo, this isn’t the end of Google or anything really near.
Google is the fourth-most valued public firm in the world. Its market worth is $2.1 trillion, trailing just Apple, Microsoft, and the AI chip darling Nvidia. It also maintains its dominance in other industries, such as display advertisements, where it dominates alongside Facebook’s parent firm Meta, and video ads on YouTube.
To put those “other” firms in context, each is worth more than Delta Air Lines’ total market value. So, yeah, Google is not going anywhere.
Nonetheless, Google faces numerous dangers to its operations, particularly from antitrust regulators.
On Monday, a federal judge in San Francisco ruled that Google must open up its Google Play Store to competitors, dealing a significant blow to the firm in its long-running battle with Fortnite creator Epic Games. Google announced that it would appeal the verdict.
In August, a federal judge ruled that Google has an illegal monopoly on search. That verdict could lead to the dissolution of the company’s search operation. Another antitrust lawsuit filed last month accuses Google of abusing its dominance in the online advertising business.
Meanwhile, European regulators have compelled Google to follow tough new standards, which have resulted in multiple $1 billion-plus fines.

Google’s Search Dominance Is Unwinding
On top of that, the marketplace is becoming more difficult on its own.
TikTok, the fastest-growing social network, is expanding into the search market. And Amazon has accomplished something few other digital titans have done to date: it has established a habit.
When you want to buy anything, you usually go to Amazon, not Google. Amazon then buys adverts to push companies’ products to the top of your search results, increasing sales and earning Amazon a greater portion of the revenue. According to eMarketer, it is expected to generate $27.8 billion in search revenue in the United States next year, trailing only Google’s $62.9 billion total.
And then there’s AI, the technology that (supposedly) will change everything.
Why search in stilted language for “kendall jenner why bad bunny breakup” or “police moving violation driver rights no stop sign” when you can just ask OpenAI’s ChatGPT, “What’s going on with Kendall Jenner and Bad Bunny?” in “I need help fighting a moving violation involving a stop sign that wasn’t visible.” Google is working on exactly this technology with its Gemini product, but its success is far from guaranteed, especially with Apple collaborating with OpenAI and other businesses rapidly joining the market.
A Google spokeswoman referred to a blog post from last week in which the company unveiled ads in its AI overviews (the AI-generated text that appears at the top of search results). It’s Google’s way of expressing its ability to profit on a changing marketplace while retaining its business, even as its consumers steadily transition to ask-and-answer AI and away from search.

Google has long used a single catchphrase to defend itself against opponents who claim it is a monopoly abusing its power: competition is only a click away. Until recently, that seemed comically obtuse. Really? We are going to switch to Bing? Or Duck Duck Go? Give me a break.
But today, it feels more like reality.
Google is in no danger of disappearing. However, every highly dominating company faces some type of reckoning over time. GE, a Dow mainstay for more than a century, was broken up last year and is now a shell of its previous dominance. Sears declared bankruptcy in 2022 and is virtually out of business. US Steel, long the foundation of American manufacturing, is attempting to sell itself to a Japanese corporation.

2024 | Supreme Court Won’t Hear Appeal From Elon Musk’s X Platform Over Warrant In Trump Case
Washington — Trump Media, The Supreme Court announced Monday that it will not hear an appeal from social media platform X about a search warrant acquired by prosecutors in the election meddling case against former President Donald Trump.
The justices did not explain their rationale, and there were no recorded dissents.
The firm, which was known as Twitter before being purchased by billionaire Elon Musk, claims a nondisclosure order that prevented it from informing Trump about the warrant obtained by special counsel Jack Smith’s team violated its First Amendment rights.
The business also claims Trump should have had an opportunity to exercise executive privilege. If not reined in, the government may employ similar tactics to intercept additional privileged communications, their lawyers contended.

Two neutral electronic privacy groups also joined in, urging the high court to hear the case on First Amendment grounds.
Prosecutors, however, claim that the corporation never shown that Trump utilized the account for official purposes, therefore executive privilege is not a problem. A lower court also determined that informing Trump could have compromised the current probe.

Trump utilized his Twitter account in the weeks preceding up to his supporters’ attack on the Capitol on January 6, 2021, to spread false assertions about the election, which prosecutors claim were intended to create doubt in the democratic process.
The indictment describes how Trump used his Twitter account to encourage his followers to travel to Washington on Jan. 6, pressuring Vice President Mike Pence to reject the certification, and falsely claiming that the Capitol crowd, which battered police officers and destroyed glass, was peaceful.

That case is now moving forward following the Supreme Court’s verdict in July, which granted Trump full immunity from criminal prosecution as a former president.
The warrant arrived at Twitter amid quick changes implemented by Musk, who bought the company in 2022 and has since cut off most of its workforce, including those dedicated to combating disinformation and hate speech.

The Supreme Court Turns Down Biden’s Government Appeal in a Texas Emergency Abortion Matter.
(VOR News) – A ruling that prohibits emergency abortions that contravene the Supreme Court law in the state of Texas, which has one of the most stringent abortion restrictions in the country, has been upheld by the Supreme Court of the United States. The United States Supreme Court upheld this decision.
The justices did not provide any specifics regarding the underlying reasons for their decision to uphold an order from a lower court that declared hospitals cannot be legally obligated to administer abortions if doing so would violate the law in the state of Texas.
Institutions are not required to perform abortions, as stipulated in the decree. The common populace did not investigate any opposing viewpoints. The decision was made just weeks before a presidential election that brought abortion to the forefront of the political agenda.
This decision follows the 2022 Supreme Court ruling that ended abortion nationwide.
In response to a request from the administration of Vice President Joe Biden to overturn the lower court’s decision, the justices expressed their disapproval.
The government contends that hospitals are obligated to perform abortions in compliance with federal legislation when the health or life of an expectant patient is in an exceedingly precarious condition.
This is the case in regions where the procedure is prohibited. The difficulty hospitals in Texas and other states are experiencing in determining whether or not routine care could be in violation of stringent state laws that prohibit abortion has resulted in an increase in the number of complaints concerning pregnant women who are experiencing medical distress being turned away from emergency rooms.
The administration cited the Supreme Court’s ruling in a case that bore a striking resemblance to the one that was presented to it in Idaho at the beginning of the year. The justices took a limited decision in that case to allow the continuation of emergency abortions without interruption while a lawsuit was still being heard.
In contrast, Texas has been a vocal proponent of the injunction’s continued enforcement. Texas has argued that its circumstances are distinct from those of Idaho, as the state does have an exemption for situations that pose a significant hazard to the health of an expectant patient.
According to the state, the discrepancy is the result of this exemption. The state of Idaho had a provision that safeguarded a woman’s life when the issue was first broached; however, it did not include protection for her health.
Certified medical practitioners are not obligated to wait until a woman’s life is in imminent peril before they are legally permitted to perform an abortion, as determined by the state supreme court.
The state of Texas highlighted this to the Supreme Court.
Nevertheless, medical professionals have criticized the Texas statute as being perilously ambiguous, and a medical board has declined to provide a list of all the disorders that are eligible for an exception. Furthermore, the statute has been criticized for its hazardous ambiguity.
For an extended period, termination of pregnancies has been a standard procedure in medical treatment for individuals who have been experiencing significant issues. It is implemented in this manner to prevent catastrophic outcomes, such as sepsis, organ failure, and other severe scenarios.
Nevertheless, medical professionals and hospitals in Texas and other states with strict abortion laws have noted that it is uncertain whether or not these terminations could be in violation of abortion prohibitions that include the possibility of a prison sentence. This is the case in regions where abortion prohibitions are exceedingly restrictive.
Following the Supreme Court’s decision to overturn Roe v. Wade, which resulted in restrictions on the rights of women to have abortions in several Republican-ruled states, the Texas case was revisited in 2022.
As per the orders that were disclosed by the administration of Vice President Joe Biden, hospitals are still required to provide abortions in cases that are classified as dire emergency.
As stipulated in a piece of health care legislation, the majority of hospitals are obligated to provide medical assistance to patients who are experiencing medical distress. This is in accordance with the law.
The state of Texas maintained that hospitals should not be obligated to provide abortions throughout the litigation, as doing so would violate the state’s constitutional prohibition on abortions. In its January judgment, the 5th United States Circuit Court of Appeals concurred with the state and acknowledged that the administration had exceeded its authority.
