Wild migratory birds likely spread a deadly strain of bird flu to dairy cows in Texas and Kansas, state and federal officials announced this week.

It is believed to be the first time the virus, a highly pathogenic avian influenza (HPAI), has been found in cows in the US. Last week, officials in Minnesota confirmed finding an HPAI case in a young goat, marking the first time the virus has been found in a domestic ruminant in the US.

According to the Associated Press, officials with the Texas Animal Health Commission confirmed the flu virus is the Type A H5N1 strain, which has been ravaging bird populations around the globe for several years. The explosive, ongoing spread of the virus has led to many spillover events into mammals, making epidemiologists anxious that the virus could adapt to spread widely in humans.

When mega pop star Taylor Swift gave a series of concerts last August at the SoFi Stadium in Los Angeles, regional seismic network stations recorded unique harmonic vibrations known as "concert tremor." A similar "Swift quake" had occurred the month before in Seattle, prompting scientists from the California Institute of Technology and UCLA to take a closer look at seismic data collected during Swift's LA concert.

The researchers concluded that the vibrations were largely generated by crowd motion as "Swifties" jumped and danced enthusiastically to the music and described their findings in a new paper published in the journal Seismological Research Letters. The authors contend that gaining a better understanding of atypical seismic signals like those generated by the Swift concert could improve the analysis of seismic signals in the future, as well as bolster emerging applications like using signals from train noise for seismic interferometry.

Concert tremor consists of low-frequency signals of extended duration with harmonic frequency peaks between 1 and 10 Hz, similar to the signals generated by volcanoes or trains. There has been considerable debate about the source of these low-frequency concert tremor signals: Are they produced by the synchronized movement of the crowd, or by the sound systems or instruments coupled to the stage? Several prior studies of stadium concerts have argued for the former hypothesis, while a 2015 study found that a chanting crowd at a football game produced similar harmonic seismic tremors. However, a 2008 study concluded that such signals generated during an outdoor electronic dance music festival came from the sound system vibrating to the musical beat.

The US Supreme Court on Tuesday heard arguments in a case seeking to limit access to the abortion and miscarriage drug mifepristone, with a majority of justices expressing skepticism that the anti-abortion groups that brought the case have the legal standing to do so.

The case threatens to dramatically alter access to a drug that has been safely used for decades and, according to the Guttmacher Institute, was used in 63 percent of abortions documented in the health care system in 2023. But, it also has sweeping implications for the Food and Drug Administration's authority over drugs, marking the first time that courts have second-guessed the agency's expert scientific analysis and moved to restrict access to an FDA-approved drug.

As such, the case has rattled health experts, reproductive health care advocates, the FDA, and the pharmaceutical industry alike. But, based on the line of questioning in today's oral arguments, they have reason to breathe a sigh of relief.

Crooks are working overtime to anonymize their illicit online activities using thousands of devices of unsuspecting users, as evidenced by two unrelated reports published Tuesday.

The first, from security firm Lumen Labs, reports that roughly 40,000 home and office routers have been drafted into a criminal enterprise that anonymizes illicit Internet activities, with another 1,000 new devices being added each day. The malware responsible is a variant of TheMoon, a malicious code family dating back to at least 2014. In its earliest days, TheMoon almost exclusively infected Linksys E1000 series routers. Over the years it branched out to targeting the Asus WRTs, Vivotek Network Cameras, and multiple D-Link models.

In the years following its debut, TheMoon’s self-propagating behavior and growing ability to compromise a broad base of architectures enabled a growth curve that captured attention in security circles. More recently, the visibility of the Internet of Things botnet trailed off, leading many to assume it was inert. To the surprise of researchers in Lumen’s Black Lotus Lab, during a single 72-hour stretch earlier this month, TheMoon added 6,000 ASUS routers to its ranks, an indication that the botnet is as strong as it’s ever been.

Missouri Attorney General Andrew Bailey yesterday sued Media Matters in an attempt to protect Elon Musk and X from the nonprofit watchdog group's investigations into hate speech on the social network. Bailey's lawsuit claims that "Media Matters has used fraud to solicit donations from Missourians in order to trick advertisers into removing their advertisements from X, formerly Twitter, one of the last platforms dedicated to free speech in America."

Bailey didn't provide much detail on the alleged fraud but claimed that Media Matters is guilty of "fraudulent manipulation of data on X.com." That's apparently a reference to Media Matters reporting that X placed ads for major brands next to posts touting Hitler and Nazis. X has accused Media Matters of manipulating the site's algorithm by endlessly scrolling and refreshing.

Bailey yesterday issued an investigative demand seeking names and addresses of all Media Matters donors who live in Missouri and a range of internal communications and documents regarding the group's research on Musk and X. Bailey anticipates that Media Matters won't provide the requested materials, so he filed the lawsuit asking Cole County Circuit Court for an order to enforce the investigative demand.

Apple has announced dates for this year's Worldwide Developers Conference (WWDC). WWDC24 will run from June 10 through June 14 at the company's Cupertino, California, headquarters, but everything will be streamed online.

Apple posted about the event with the following generic copy:

Join us online for the biggest developer event of the year. Be there for the unveiling of the latest Apple platforms, technologies, and tools. Learn how to create and elevate your apps and games. Engage with Apple designers and engineers and connect with the worldwide developer community. All online and at no cost.

As always, the conference will kick off with a keynote presentation on the first day, which is Monday, June 10. You can be sure Apple will use that event to at least announce the key features of its next round of annual software updates for iOS, iPadOS, macOS, watchOS, visionOS, and tvOS.
