ACSH - July 10, 2017 - 6:00pm

Mycobacterium tuberculosis (Mtb), with its mere ~4,000 genes, has been outsmarting us for decades. One look at the numbers illustrates this clearly. The disease caused by Mtb, tuberculosis (TB), is one of the top ten causes of death in the world. It currently infects roughly 1.5 billion people worldwide and causes 1.8 million deaths every year - most commonly in India, Indonesia, China, Nigeria, Pakistan and South Africa.

600 Attend To Outreach Event In Venice

Science2.0 - July 10, 2017 - 2:56pm
On Saturday, July 8th, the "Sala Perla" of the Palazzo del Casinò was crowded by 600 attendees, who filled all seats and then some. The event, titled "Universo: tempo zero - breve storia dell'inizio", was organized in conjunction with the international EPS conference, which takes place until this Wednesday at Lido of Venice. It featured a discussion between the anchor, Silvia Rosa Brusin, and a few guests: Fabiola Gianotti, general director of CERN; Antonio Masiero, vice-president of INFN; and Mirko Pojer, responsible of operations of the LHC collider. The program was enriched by a few videos, and by readings by Sonia Bergamasco and jazz music by Umberto Petrin. -->

Taking the High Road: Marijuana Tester for Drivers Taking Shape

ACSH - July 7, 2017 - 5:58pm

Researchers have figured out how to accurately measure "a fundamental physical property" in THC, pot's primary active ingredient. This scientific achievement, never achieved before they say, lays the "technical groundwork for manufacturers to develop accurate devices" to measure impairment while driving.

The High Road: Marijuana Tester for Drivers Taking Shape

ACSH - July 7, 2017 - 5:58pm

As states across the country legalize marijuana use, either for medicinal or recreational purposes, a predictable outcome is that over time more drivers will get behind the wheel under its influence. However, as compared to drivers pulled over for suspicion of drinking and drunk driving, determining impairment from smoking is significantly harder to do.

Brain Performance Not Affected By Menstrual Cycle

Science2.0 - July 7, 2017 - 12:37pm
Men who worry that women may not make the right decisions during a menstrual cycle, and women who claim biology is a valid excuse for being a jerk, you're both out of luck.

An examination of three aspects of cognition across two menstrual cycles found that the levels of estrogen, progesterone and testosterone had no impact on working memory, cognitive bias or ability to pay attention to two things at once.

While some hormones were associated with changes across one cycle in some of the women taking part, these effects didn't repeat in the following cycle. Overall, none of the hormones the team studied had any replicable, consistent effect on study participants' cognition.

Gonorrhea That Will Never Be Gone

ACSH - July 7, 2017 - 12:30pm

In the 1980s, a case of gonorrhea would have been easily treated with a course of antibiotics. Today, this is not the case. An announcement by the World Health Organization calls attention to the increasing problem of antibiotic resistance in Neiserria gonorrheae – the bacteria that causes this sexually transmitted disease.

LHCb Unearths New Doubly-Charmed Hadron Where Marek Karliner And Jonathan Rosner Ordered It

Science2.0 - July 7, 2017 - 7:17am
[UPDATE: see at the bottom for some additional commentary following a post on the matter by our friend Lubos Motl in his blog, where he quotes this piece and disagrees on the interest of finding the Xi mass in perfect agreement with an a priori calculation.]

It is always nice to learn that a new hadron is discovered - this broadens our understanding of the extremely complicated fabric of Quantum Chromodynamics (QCD), the theory of strong interactions that govern nuclear matter and are responsible for its stability.  -->

'How Sweet It Is' Isn't Supposed to Refer to Swimming Pools!

ACSH - July 6, 2017 - 8:00pm

Though chlorine has been attacked as being "dangerous" to one's health, it's got a health-supporting side, too. In pools it combines with nitrogen-containing compounds to take them out of circulation. How do they get there in the first place? A recent study showed that (like it or not) people pee in pools — and the presence of artificial sweeteners proves it.
