But automatically calling something cancer can lead to aggressive treatment, even if the cancer in question is unlikely to cause problems. For prostate cancer, a biopsy showing a grade of Gleason 6 (also known as Grade Group 1) is considered low or very low risk. In breast cancer, diagnosis of ductal carcinoma in situ, or DCIS, is similarly low or very low risk, representing the very earliest, noninvasive stage of the disease. These findings make up about 20 percent to 25 percent of all prostate and breast cancer diagnoses in the United States, involving about 100,000 people annually. Accordingly, many make the understandable choice of aggressive treatment they don’t require.

What lies beneath Land mines left by Russian forces in Ukraine pose a deadly threat to Kyiv's military - and civilians in liberated territory. On average, anti-vehicle mines caused more incidents with multiple fatalities than anti-personnel mines did. GICHD has documented at least 12 types of anti-personnel mines and nine types of anti-vehicle mines in use in Ukraine. Formerly occupied towns in Kyiv; Sumy, Chernihiv, Mykolaiv and Kharkiv oblasts all saw a large number of mines, especially anti-personnel mines, left in place, Mathewson said. Ukraine is a signatory to the 1997 Convention on the Prohibition of the Use, Stockpiling, Production and Transfer of Anti-Personnel Mines and on their Destruction, and had been destroying its anti-personnel mines when the war began.

Explore the universe with news on fascinating discoveries, scientific advancements and more.CNN —Researchers using a cutting-edge technique have discovered hidden details in two ancient Egyptian paintings in the Theban Necropolis, near the River Nile, that date back more than 3,000 years. Using portable chemical imaging technology, the researchers identified alterations made by the artists that are rare in Egyptian paintings, commonly thought to be the product of highly formalized workflows. We want to understand how these paintings were made.”X-ray fluorescence in chemical imaging technology helps to reveal alterations made in Egyptian tomb paintings that may not seem obvious to the naked eye. “It demonstrates the potential value of quantitative data, obtained through scientific analysis, for a more comprehensive and less subjective interpretation of ancient Egyptian art,” she said. “And the adaption of portable (X-ray) instruments as mobile devices designed for use in the field is a very exciting advancement in the study of ancient Egyptian wall paintings.”

We have also learned over time that not all breast cancer tumors grow or spread at the same rate. For example, a type of breast cancer that I’ve studied, called ductal carcinoma in situ — also known as stage 0 breast cancer — may never progress to invasive disease in a person’s lifetime, and so may require less therapy. Detecting cancer becomes more challenging when trying to distinguish cancer, which also appears white on a mammogram, from dense breast tissue. The task force acknowledged that dense breasts can increase a woman’s risk of breast cancer and that certain race or ethnicity groups are at higher risk for early-onset breast cancer. Black women under 50, for example, die of breast cancer at twice the rate of white women under 50 in the United States.

CNN —Researchers have embarked on an ambitious global initiative to discover and record marine life hidden in the world’s oceans. Ocean Census aims to identify 100,000 unknown species in the next 10 years, allowing scientists to better understand and protect the deep-sea ecosystem. The initiative builds on past projects such as the Census of Marine Life, which concluded in 2010 and identified 6,000 potential new ocean species. Ocean Census will also help to identify how marine ecosystems are responding to the climate crisis, and assess how marine life could adapt to a warmer climate. The project is being led by Nekton, a UK-based marine science and conservation institute, and funded by The Nippon Foundation, a nonprofit foundation based in Japan.

Elon Musk said the destruction of the launch pad is his biggest concern about the Starship launch. The launch pad would melt if Starship "fireballed" on launch day, he said. SpaceX is scheduled to launch Starship on Monday, but Musk warned about possible delays. His biggest concern was that a "fireball" incident could melt the launch pad if one of the engines failed. "If we get far enough away from the launch pad before something goes wrong, I think I would consider that a success.

ORLANDO, Florida, April 14 (Reuters) - Engineering a soft landing is hard. Blinder posits that the soft landing parameters of avoiding recession completely are too narrow.

REUTERS/Todd KorolPrime Minister Justin Trudeau’s Liberal government is expected to table its long-awaited workforce transition bill this spring, ahead of economic changes expected as they pursue ambitious goals to slash climate-warming emissions. The government of Alberta, Canada’s main crude-producing province, says the legislation will dismantle the oil and gas industry that makes up 5% of Canada’s GDP. The oil and gas sector employs around 185,000 workers, making the bill a hot topic in Alberta ahead a provincial election in May.

☆ It's a myth that ancient Egyptians pulled mummy brains out by the nose — they likely scrambled them instead, says an expert who tried it

There's a good chance you were told ancient Egyptians pulled chunks of brains out through the nose. Experiments suggest there was a much easier way to do this: scrambling the brains, an expert said. It's likely embalmers used hooks to liquefy the brains and pour them out, he said. "'Hooking it out in pieces is not particularly efficient/successful," he told Insider in an email. For instance, Pharaoh Thutmose I, Queen Tiye, the main wife of pharaoh Amenhotep III, and Pharaoh Amenhotep I were all found with brain tissue still in place.

The Bank of Japan delivers the last G7 central bank policy decision of the year on Tuesday, and those hoping that a traditional dose of BOJ dovishness will ease the selling pressure currently slamming world markets may be disappointed. To be sure, the BOJ will almost certainly keep its key interest rate at an ultra-loose -0.10% and maintain its 'yield curve control' policy, but the winds of change are starting to blow. A hawkish turn from the BOJ would put a year-end rebound even further out of reach for world stocks. China's central bank, meanwhile, is likely to keep benchmark lending rates unchanged for a fourth straight month on Tuesday, although expectations for monetary easing are rising.

A toaster-sized device called MOXIE is tucked inside NASA's Perseverance rover, which landed on Mars in 2021. NASA's Perseverance rover descends onto Mars, on February 18, 2021. The oxygen atoms then combine with each other to produce oxygen gas. MOXIE splits carbon dioxide into carbon monoxide and oxygen atoms, before the single oxygen atoms combine to make breathable oxygen. Researchers imagine a jumbo version of MOXIE, approximately 100 times larger, could produce oxygen at the same rate as several hundred trees.

"Excluzând zonele de la periferia Groenlandei şi Antarcticii, deci păstrând în acest studiu 70% dintre gheţarii planetei, s-a trecut în 20 de ani de la o micşorare medie care depăşea cu puţin o treime de metru pe an, la o două treimi de metru pe an", a subliniat Romain Hugonnet. "În 20 de ani, s-a dublat viteza de micşorare. Este foarte îngrijorător", a adăugat el.Gheţarii din Alaska, din Alpi şi din Islanda fac parte dintre aceia care s-au micşorat cel mai repede.Concluziile generale ale studiului concordă cu cele formulate de Grupul interguvernamental de experţi în evoluţia climei (GIEC), care conţineau însă marje foarte mari de incertitudine. "Pe termen scurt, gheţarii care se topesc din ce în ce mai repede vor furniza tot mai multă apă către râuri, servind astfel ca un fel de tampon în anumite regiuni precum India sau în Anzi în perioadele aride. Dar, apoi, se va atinge un maxim, iar cantitatea de apă va scădea rapid, până când nu va mai exista deloc", a avertizat acelaşi cercetător, estimând că "peste câteva decenii, majoritatea regiunilor vor intra pe această pantă descendentă".

☆ NASA: Roverul Perseverance a reuşit o nouă performanţă, transformând dioxidul de carbon din atmosfera planetei Marte în oxigen
▼ + stars: | 2021-04-22 | by ( Publika.Md - Aici Sunt Știrile | ) www.publika.md time to read: +2 min

"Este o primă încercare crucială de a converti dioxidul de carbon în oxigen pe Marte", a declarat Jim Reuter, administrator asociat la NASA.Demonstraţia a avut loc pe 20 aprilie şi NASA speră că viitoarele versiuni ale instrumentului experimental folosit ar putea pregăti terenul pentru explorarea umană.Procesul nu numai că ar putea produce oxigen pentru ca viitorii astronauţi să respire, dar ar putea, de asemenea, să evite transportarea unor cantităţi mari de oxigen de pe Pământ, esenţiale pentru a propulsa racheta pentru călătoria de întoarcere. "Experimentul de utilizare a resursei de oxigen in-situ pe Marte" (Moxie) este o cutie aurie de mărimea unei baterii auto, situată în partea din faţă dreapta a rover-ului. Aceasta foloseşte electricitatea şi chimia pentru a diviza moleculele de CO2, producând oxigen şi monoxid de carbon.În primul său experiment, Moxie a produs cinci grame de oxigen, suficiente pentru ca un astronaut cu activitate normală să poată respira timp de zece minute.Inginerii responsabili de Moxie vor efectua acum mai multe teste şi vor încerca să mărească acest prim rezultat.Instrumentul a fost conceput pentru a genera până la zece grame de oxigen pe oră.Conceput de prestigiosul Institut de Tehnologie din Massachusetts (MIT), Moxie a fost fabricat cu materiale rezistente la căldură pentru a tolera temperaturi de 800 de grade Celsius, necesare funcţionării sale.Un strat subţire auriu îl împiedică să radieze căldura şi să deterioreze roverul.Potrivit inginerului MIT Michael Hecht, un Moxie de o tonă - acesta cântăreşte 17 kilograme - ar putea produce cele aproximativ 25 de tone de oxigen necesare unei rachete care să decoleze de pe Marte.Producerea oxigenului din atmosfera planetei Marte, compusă în proporţie de 96% din dioxid de carbon, s-ar putea dovedi mai uşoară decât extragerea gheţii de sub suprafaţa planetei pentru a produce oxigen prin electroliză.Perseverance a aterizat pe Marte pe 18 februarie cu misiunea de a căuta urme de viaţă fosilă.

De aceea, posibilitatea reconstrucției imediate a sânului se ia în calcul încă de la etapa de planificare a intervenției la Medpark. Toate studiile știintifice au demonstrat că reconstrucția sânului nu influențează riscul de recidivă locală. Reconstrucția sânului imediată după mastectomie îmbunătățește semnificativ calitatea vieții femeilor, reducând substanțial impactul psihologic negativ dat de pierderea sânului.”Alte avantaje ale intervenției combinate sunt:O singură administrare de anestezie. După intervenție pacienta este monitorizată, efectuează investigații postoperatorii, pansamente și tot acest proces va avea loc o singură dată.

Pe Marte, 96% din compoziția atmosferei este dioxid de carbon, în timp ce doar 0,13% este oxigen. Sistemul MOXIE (Mars Oxygen in Situ Resource Utilization Experiment) ar produce oxigen asemeni unui copac – preia dioxidul de carbon cu o pompă și îl transformă în oxigen printr-un proces electrochimic. În primă instanță, NASA va testa felul în care actualul echipament MOXIE de pe Marte, de dimensiunea unui toaster, funcționează și cât de eficient este în a produce oxigen. Lecțiile învățate vor fi aplicate pentru dezvoltarea unui sistem mai complex pentru viitoarea măsură. Un sistem final MOXIE ar putea fi de dimensiunea unui cuptor de bucătărie și ar cântări în jur de 1000 de kilograme.
