Mauricio Diazgranados Is a Botanist in a Hurry
  + stars: | 2023-07-31 | by ( Jennie Erin Smith | ) www.nytimes.com   time to read: +2 min
A decade ago, when Dr. Diazgranados was head of Bogotá’s botanical garden, he took on the construction of a new herbarium and the largest greenhouse in the Americas, before a change in mayoral administrations swept out its leadership and he packed his bags for London. He published a world checklist of useful plants, a virtually boundless, searchable database of species that supply food, medicine, fiber and fuel, or help mitigate the effects of climate change. “What I need to do now is figure out how this institution can respond better to these challenges.”Dr. Diazgranados’s offices are in the garden’s glass-walled plant research laboratory, nestled in an old-growth oak forest. Here, researchers draw on collections of resins, seeds and plants preserved in spirits or in silica powder, along with vast banks of DNA samples and plant chemicals. The bridge between the botanical garden as a public attraction and a research facility is its living collection, whose plants are routinely sampled to help answer questions in plant genetics, structure and evolution.

At a time when the mighty woolly mammoth roamed the Earth, some 46,000 years ago, a minuscule pair of roundworms became encased in the Siberian permafrost. Millenia later, the worms, thawed out of the ice, would wriggle again, and demonstrate to scientists that life could be paused — almost indefinitely. The discovery, published this week in the peer-reviewed journal PLOS Genetics, offers new insight into how the worms, also known as nematodes, can survive in extreme conditions for extraordinarily long periods of time, in this case tens of thousands of years. In 2018, Anastasia Shatilovich, a scientist from the Institute of Physicochemical and Biological Problems in Soil Science RAS in Russia, thawed two female worms from a fossilized burrow dug by gophers in the Arctic.

Dr. Susannah Hills John AbbottTo my surprise, I was diagnosed with skin cancer on my scalp. Basal cell cancer. Still, it seemed so strange to me that my skin cancer showed up on my scalp, underneath a covering of hair. An exam should be done every year to monitor unusual skin changes, or if you are at higher risk for developing skin cancer. I learned the hard way that anyone can get skin cancer and it can show up where you least expect.

Scientists revived a 46,000-year-old worm that was living in Siberian permafrost. When they brought it back to life, the worm started having babies. When they revived it, the worm started having babies via a process called parthenogenesis, which doesn't require a mate. According to a press release, the worm spent thousands of years in a type of dormancy called cryptobiosis. This new species, however, called Panagrolaimus kolymaensis, was dormant for tens of thousands of years longer.

CNN —Scientists have revived a worm that was frozen 46,000 years ago — at a time when woolly mammoths, sabre-toothed tigers and giant elks still roamed the Earth. This a major finding,” he said, adding that other organisms previously revived from this state had survived for decades rather than millennia. Five years ago, scientists from the Institute of Physicochemical and Biological Problems in Soil Science in Russia found two roundworm species in the Siberian permafrost. The worm was found in the Siberian permafrost. But still, they didn’t know whether the worm was a known species.

When she celebrated her birthday last year, she told The Rye Record, “I’m glad I can still speak and have my sense of humor, but I would caution you not to try and live to be 112!”She had been the oldest known living person in New York State, according to LongeviQuest, which maintains a database of supercentenarians, people who have lived into a 12th decade. Mrs. Levy was one of more than 700 people, all 95 or older, recruited since 1998 to participate in a study by the Institute for Aging Research at the Albert Einstein School of Medicine in the Bronx to learn the genetic reasons for their unusually long, healthy lives. “It’s not luck,” Dr. Nir Barzilai, an endocrinologist who directs the institute, said by phone. “They exceeded luck. The biggest answer is genetics.”Using the blood and plasma of the test group, all Ashkenazi Jews — a comparatively homogeneous population whose genetic variations are easier to spot — the institute’s Longevity Genes Project has discovered gene mutations that are believed to be responsible for slowing the impact of aging on people like Mrs. Levy and protecting them against high cholesterol, heart disease, diabetes and Alzheimer’s disease.

Olive oil may lower risk of death from dementia
  + stars: | 2023-07-27 | by ( Kristen Rogers | ) edition.cnn.com   time to read: +5 min
Whether olive oil is linked with risk of dementia-related death had never been studied until now, according to the authors. Over a follow-up period of 28 years, regardless of diet quality, eating more than half a tablespoon of olive oil per day was associated with a 28% lower risk of dying from dementia, compared with participants who never or rarely consumed olive oil. Additionally, replacing a daily teaspoon of mayonnaise or margarine with the same amount of olive oil was correlated with an 8% to 14% lower risk of dementia-related death, the authors found. “It is also possible that olive oil has an indirect effect on brain health by benefiting cardiovascular health,” she added. Besides cooking with olive oil, you can also use it to make salad dressings or vinaigrettes, mayonnaise, pesto or bread dip.

However, when the scientists compared their horsehair worm genomes with genomic information from other animals, something was missing, Cunha told CNN. Two live tangled freshwater horsehair worms, scientifically called Gordionus violaceus, were found in Germany. Mysteries remain about the worms’ movementsAs useful as cilia are, horsehair worms seem to be doing just fine without them, the scientists reported. To date, scientists have identified several hundred species of freshwater horsehair worms and five species of marine horsehair worms. Marine horsehair worms spend their entire lives in water, but freshwater species are only aquatic as adults.

REUTERS/Amir Cohen/File PhotoREHOVOT, Israel, July 17 - Every year, egg farmers kill 7 billion day-old male chicks because they cannot grow up to lay eggs and are the wrong breed for meat. A laboratory in Israel has a solution: what if the male eggs don't hatch? Day-old male chicks are normally "either macerated or suffocated or electrified. In some countries they do not even bother to cull their males properly,” explained Cinnamon, principal investigator at Israel’s Volcani Institute, which works to attain food security and food safety. The unhatched male eggs can be used for other purposes such as animal feed.

CNN —A number of high-profile Jewish groups are denouncing Democratic presidential contender Robert F. Kennedy Jr.’s false remarks that “Ashkenazi Jews and Chinese” people are “most immune” to Covid-19. “Covid-19 is targeted to attack Caucasians and Black people. While there are disproportionate rates of Covid-19 illness and death across different demographics, this has been attributed to racial disparities, not genetics. Black and Hispanic people also faced a higher risk of coronavirus infection and were more than twice as likely to be hospitalized. He also railed against the coronavirus vaccine and vaccine mandates.

Agriculture is extremely vulnerable to the impacts of changing climate conditions and although changes to temperature, rainfall patterns, and frost might extend a growing season or enable the cultivation of different crops, climate change also introduces major challenges for farming.

How often should you poop?
  + stars: | 2023-07-12 | by ( Kristen Rogers | ) edition.cnn.com   time to read: +6 min
CNN —Everyone poops, but it turns out we don’t all need to poop every day. It’s helpful to know what your poop looks like in addition to just how often you poop. But if you’re excessively straining when trying to poop or feeling like you haven’t totally emptied your bowel, you may need to make changes to either poop more often or have healthier stool quality, experts said. But if we’re stressed, hormones and nervous system changes can prevent poop from moving toward the rectum, resulting in constipation. But don’t delay — the right time to poop is when you’re feeling the urge to do so, experts said.

And now on the eve of her final Women’s World Cup, Rapinoe has taken aim at recent policies that aim to ban transgender women from competing in women’s sports. “We as a country are trying to legislate away people’s full humanity,” she told Time magazine in an interview. In recent months, transgender women’s participation in a number of sports has been prohibited with the introduction of new regulations. The House bill would prohibit transgender women and girls from playing on sports teams consistent with their gender identity. “I see trans women as real women.

Spider mites are tiny arachnids, distant cousins of spiders, smaller than the tip of a standard ballpoint pen. Living together in dense colonies can make for fierce competition in finding a mate, especially because female spider mites only use the sperm from the first male with which they mate. Males will guard females that are nearly mature, so that as soon as the females are set to mate, the males will be ready. While farmers and gardeners often revile spider mites as plant-eating pests, many biologists use them as model organisms. “I hope they are fascinated about what type of sophisticated behaviors have evolved, even in such tiny animals as spider mites,” he said.

CNN —The US Food and Drug Administration is expected to decide on Thursday whether to grant traditional approval to the Alzheimer’s drug Leqembi, the first medicine proven to slow the course of the memory-robbing disease. Leqembi, from drugmakers Eisai and Biogen, received accelerated approval in January based on evidence that it clears amyloid plaque buildups in the brain that are associated with Alzheimer’s disease. But because of an earlier coverage decision by CMS, which provides insurance coverage for many elderly patients with Alzheimer’s through Medicare, the drug hasn’t been widely used. People with more advanced forms of the disease may not benefit from the drug, he said, and may face increased safety risks. Broad Medicare coverage of Leqembi and similar types of medications to slow the progression of Alzheimer’s disease would probably have a big impact on the program’s spending.

Authorities in China took multiple steps to tighten rules and ethical standards affecting human gene editing in the wake of the revelations about his previous research. But the scientist’s release of a new proposal involving gene editing of embryos has scientists and medical ethics experts concerned – and confused. Genetic manipulation of human embryos – both viable and nonviable ones – is typically tightly controlled globally and some countries ban all such research, experts say. But there is robust global debate around allowing genome editing of human embryos to treat serious genetic conditions or expanding research. Chinese law does not allow gene-edited human embryos used in research to be implanted into humans, or developed for more than 14 days.

However, experts who treat and study menopause say the study is unable to draw a direct connection to later-life dementia and that the overall benefits of hormone replacement therapy, or HRT, far outweigh the risks for many patients. “One finding in the study was a link between dementia and the use of HRT for a very short time span, under a year. Researchers compared people with dementia who had used hormone therapy, even briefly, with those from the larger group who had not. The chance of being diagnosed with dementia went up with years spent on HRT, the study found. When women used 12 or more years of hormone therapy, the association with a diagnosis of dementia rose to 74%, Pourhadi said.

How to repel mosquitoes, according to science
  + stars: | 2023-06-24 | by ( Kate Golembiewski | ) edition.cnn.com   time to read: +8 min
Here’s the lowdown on how mosquitoes hunt us, what attracts them, and what scientists recommend for keeping them at bay. The science of mosquito bitesMost of the time, mosquitoes drink plant nectars and juices, and even help pollinate flowers. “How attractive you think you are to mosquitoes might not necessarily correlate with how attractive you actually are to the mosquitoes,” McMeniman said. The itchiness and discomfort from mosquito bites come later when the perpetrator is no longer at risk of getting swatted. No silver bullet exists to protect yourself from mosquito bites, but get a good bug spray and reapply it as needed.

But while muscle memory is real, that’s not what is actually going on in your body. Understanding how both kinds of muscle memory work can help you get off to a strong start if you’re establishing a new fitness routine or rebooting one after a break. Physiological muscle memoryThe physiological side of muscle memory has to do with the ability to quickly regain lost muscle. This form of muscle memory occurs because when you first build muscle, your body adds new cells to those muscles. Science says another type of muscle memory is related to the regrowth of actual muscle tissue.
