Dietary supplements containing Garcinia cambogia extract and green tea can cause similar liver, finds an analysis of the Drug-Induced Liver Injury Network.G. cambogia, alone or with green tea, are touted by companies who sell alternatives to medicine and bought by people who believe in them, commonly for weight loss. But the analysis reveals that in the period covered the drug-induced liver injury caused by the supplement led to 91% being hospitalized, while 2 died and 1 survived due to a liver transplant

Citrus canker, caused by the bacterium Xanthomonas citri, was first identified in the United States near the Florida-Georgia border in 1910 and then raged across southern states. It was considered eradicated in 1933, thanks to chemical intervention, but in 1995 it was found again in Miami-Dade County, Florida. This time, Florida found it impossible to eliminate and worked on containment. It moved to Louisiana in 2014 and 2016, USDA confirmed the presence of the Asiatic A strain, a more severe form of citrus canker, on two sour orange trees in Houston.

Microfossils found in rock samples retrieved in Australia more than 60 years ago (DOI 10.1126/science.abj2927) fill an approximately 25-million-year gap in knowledge by reconciling the molecular clock - or pace of evolution - with the fossil spore record - the physical evidence of early plant life gathered by scientists over the years.This reconciliation supports an evolutionary-developmental model connecting plant origins to freshwater green algae, or charophyte algae. The “evo-devo” model posits a more nuanced understanding of plant evolution over time, from simple cell division to initial embryonic stages, rather than large jumps from one species to another.

It's common when the subject of stupid behavior comes up, like belief in supplements or acupuncture over medicine, for someone to post a picture of Darwin or recommend them for a Darwin award.It's scientifically wrong - Aedes aegypti is an ecologically useless mosquito that is only a disease vector for yellow fever, dengue fever, Zika, etc. yet still exists - but it may also be a sign of dysfunctional psychological characteristics, such as exploitative attitudes towards others, hostility, and low self-esteem. At least according to survey results in PLOS ONE.

A new lightweight fabric is 3D-printed from nylon plastic polymers comprises hollow octahedrons (eight equal triangular faces) that interlock with each other.While soft, the fabric can be wrapped within a flexible plastic envelope and vacuum-packed, which makes it rigid - 25 times stiffer or harder to bend. This ‘wearable structured fabrics’ could be optimized to harden automatically, or tuned manually when needed. Modern chain mail, anyone? That LARP weekend just got a lot more fun to watch.

Urban people may believe nature is balanced and peaceful and pristine but biologists know that nature really just wants to suck the nutrients from your dead corpse.Insects have more nature to worry about, in the form of the delicate stalk and pretty white flowers of Triantha occidentalis, the first new carnivorous plant to be identified by botanists in 20 years. It is notable for the unusual way it traps prey with sticky hairs on its flowering stem.Triantha occidentalis in a bog at Cypress Provincial Park, British Columbia, Canada. Credit: Danilo Lima

Nearly 30 years ago, scientists agreed that for clinical trial results to be valid for both sexes, they needed more women.Yet women seem to be a lot less likely to sign up for clinical trials for cardiovascular disease. The authors of a new paper outline the issue as to why:Differential Care – Low rates of referral to cardiologists and specialty programs for more aggressive care might lead to fewer women being treated by specialists recruiting for clinical trials.

A fearsome beast soared above the ancient, vast inland sea once that once covered covering much of outback Queensland. This newly found pterosaur, named Thapunngaka shawi, was discovered in Wanamara Country, near Richmond in North West Queensland.It's the stuff of nightmares, with a spear-like mouth containing 40 giant teeth and a wingspan around 20 feet. We may imagine it to be like a big bird or a bat but that is not so, according to University of Queensland doctoral student Tim Richards: "Pterosaurs were a successful and diverse group of reptiles – the very first back-boned animals to take a stab at powered flight.”

Light that goes into that black hole doesn’t come out, so we shouldn’t be able to see anything behind one, but if a black hole is warping space, bending light and twisting magnetic fields around itself, then according to Einstein's theory of general relativity direct observation of light from behind a black hole should be possible.Now it has happened. Material falling into a supermassive black hole powers the brightest continuous sources of light in the universe, and as it does so, forms a corona around the black hole. This light – which is X-ray light – can be analyzed to map and characterize a black hole.

Smartphones tout 'dark mode' as an energy-saving feature, because darker-colored pixels use less power than lighter-colored pixels.It's mostly an intellectual placebo, finds a new study, because of the way most people use their phones on a daily basis. The study looked at six of the most-downloaded apps on Google Play: Google Maps, Google News, Google Phone, Google Calendar, YouTube and Calculator. The researchers analyzed how dark mode affects 60 seconds of activity within each of these apps on the Pixel 2, Moto Z3, Pixel 4 and Pixel 5.

A recent blood group analysis of three Neanderthals and one Denisovan confirm their African origin, Eurasian dispersal, and interbreeding with early Homo sapiens. Intriguingly, it also added evidence of low genetic diversity and possible demographic fragility.Neanderthals and Denisovans are extinct hominin lineages but were present throughout Eurasia from 300,000 to 40,000 years ago. This paper isn't the first time they have been sequenced but using the genes underlying blood groups in previously sequenced genomes of one Denisovan and three Neanderthal females who lived 100,000 to 40,000 years ago allowed scholars to identify their blood groups.

Blood pressure is a risk factor for a heart event and angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) are common prescriptions. Both types of medicines work on the renin-angiotensin-aldosterone system, a group of related hormones that act together to regulate blood pressure. ACE inhibitors lower blood pressure by blocking an enzyme early in the system so that less angiotensin, a chemical that narrows blood vessels, is produced, and blood vessels can remain wider and more relaxed. ARBs block receptors in the blood vessels that angiotensin attaches to, diminishing its vessel-constricting effect.
