Hong Kong this week unveiled new stock exchange rules that will allow listings of unprofitable biotech companies, plus dual-class share structures.

Bottom line: The revised regs, which go into effect shortly, could attract some highly-valued U.S. biotech startups.

Conventional wisdom is that the new rules will act as a magnet for many Chinese companies that otherwise would list in the U.S., thus improving the odds of "holding onto" the next Alibaba.

More interesting is an argument we're hearing from stateside biotech investors, who believe many U.S.-based biotech "unicorns" will look east as a way to maintain their high valuations. Their idea is that there will be an initial deluge of Asia-based money because of the new diversification opportunity, and that could result in artificially high multiples. Sure it's cynical, but that doesn't make it wrong.

A viral TikTok challenge is leading students nationwide to shatter mirrors, steal fire alarms and intentionally clog toilets, The Washington Post reports.

Driving the news: Dubbed the the “Devious Licks challenge, students are showing off their "devious licks" on TikTok — with a sped-up version of "Ski Ski BasedGod" by rapper Lil’ B playing in the background.

Axios-Ipsos poll: People of color face more environmental threats

Americans of color are much less likely than white Americans to experience good air quality or tap water or enough trees or green space in their communities, and they're more likely to face noise pollution and litter, a new Axios-Ipsos poll finds.

The big picture: Our national survey shows Black and Hispanic Americans are more likely than their white counterparts to live near major highways or industrial or manufacturing plants — and to have dealt in the past year with water-boil notices or power outages lasting more than 24 hours.

FDA advisory panel recommends Pfizer boosters for those 65 and older

A key Food and Drug Administration advisory panel on Friday overwhelmingly voted against recommending Pfizer vaccine booster shots for younger Americans, but unanimously recommended approving the third shots for individuals 65 and older, as well as those at high-risk of severe COVID-19.

Why it matters: While the votes are non-binding, and the FDA must still make a final decision, Friday's move pours cold water on the Biden administration's plan to begin administering boosters to most individuals who received the Pfizer vaccine later this month.
