The discovery, made by an international team along with NASA researchers, and described in the paper published in Nature Communications, provides more evidence that chemical reactions in asteroids can make some of life's ingredients, which could have been delivered to ancient Earth by meteorite impacts or perhaps the infall of dust.

The growing problem of low egg reserve is one of the most significant factors contributing to lower fertility rates in urban women. Stress, pollution, pesticide exposure, and smoking and alcohol addiction are all major causes of this condition. A recent study found that one in every two women who were unable to conceive had a low egg reserve. Previously, it was a problem that arose with increasing age; however, this has changed. Low egg reserve is a common concern among today's young girls, with women as young as 27 years old experiencing infertility as a result.

For decades, astronomers have detected smaller black holes equal in mass either to a few suns or giant black holes with mass similar to millions of suns but the missing-link of black holes in between those sizes have eluded discovery. The existence of these intermediate-sized or massive black holes has long been theorised but finding them has proven difficult as the light emitted by objects falling into them is not easy to detect.

While studies have shown the efficacy of antidepressant medications for treatment of depression disorder, these medications' effect on patients' overall well-being and health-related quality of life remains controversial. Now, researchers from King Saud University in Saudi Arabia found that antidepressants are not associated with significantly better health-related quality of life.

According to the US Space Weather Prediction Center (SWPC), an X2.2 flare occurred at 11.57 p.m EDT on April 19. The flare erupted from a region just beyond the southwest limb of the Sun - likely former Region 2992. The strong flare was associated with multiple bursts on specific radio frequencies but did not result in coronal mass ejection (CME)."Forecasters are waiting for available coronagraph imagery from the NASA/SOHO LASCO instrument to confirm if a CME took place, and if so, analyse accordingly," SWPC said.

In an international collaborative study, researchers from Australia, Denmark and Finland investigated how individuals of the same population differ in their ability to survive on various diets. The researchers utilised a genetic reference panel consisting of roughly 200 closely related fruit fly strains (Drosophila melanogaster). The flies were fed six different diets containing high concentrations respectively of protein, sugar, starch, coconut oil or lard, or a combination of sugar and lard.

A team from Tel Aviv University showed that a mixture of the three food supplements, each approved by the US Food and Drug Administration (FDA), appears to be avery capable of inhibiting replication of RNA viruses in a remarkable way', Times of Israel reported.

The estimated diameter of the largest icy comet nucleus is approximately 80 miles (128 km), making it larger than the state of Rhode Island, NASA said on Tuesday, Xinhua news agency reported.

The 4-member multinational crew will launch on a SpaceX Falcon 9 rocket and will travel to and from the space station in a SpaceX-built Dragon spacecraft. The Ax-1 crew members are Commander Michael Lopez-Alegria of Spain and the US, Pilot Larry Connor of the US, and Mission Specialists Eytan Stibbe of Israel and Mark Pathy of Canada.

At least 17 solar eruptions from a single sunspot on the sun have blasted into space in recent days, and may reach Earth as moderate geomagnetic storms by Thursday. The sun eruptions originated from an overactive sunspot, called AR2975, which has been firing off flares since Monday (March 28). The stellar event may also cause some moderate sky storms on Earth, Space.com reported.
