7.2 Million-Year-Old Jawbone Indicates Oldest Hominin Lived in Europe, Not Africa

7.2 Million-Year-Old Jawbone Indicates Oldest Hominin Lived in Europe, Not Africa There’s good practical reason for that — East Africa is where many of the oldest (and most ape-like) hominid fossils have been found.This species is known from one fossilized jaw, recovered in Greece, and an upper molar found in Azmaka, Bulgaria.

ExoMars Lander Crashed Because It Thought It Was Underground

ExoMars Lander Crashed Because It Thought It Was Underground However, the Schiaparelli lander encountered issues during its descent and was lost.The saucer-shaped Schiaparelli lander undocked from the ExoMars Trace Gas Orbiter and started its descent on October 19th of last year.

Designer Virus Tells the Immune System How to Fight Cancer

Designer Virus Tells the Immune System How to Fight Cancer Most attempts to fight cancer with the body’s natural defenses are based on “disinhibiting” your immune system.However, stimulating the immune system to specifically fight the cancer is much more challenging.

Curiosity Data Suggests Ancient Martian Lake Could Have Harbored Life

Curiosity Data Suggests Ancient Martian Lake Could Have Harbored Life NASA has previously released data from Curiosity that supports the idea that liquid water once flowed in Gale Crater (above).The new study is based on a detailed analysis of data from three and a half years of drill samples from Curiosity.

Battery-Free Pacemaker Is Powered by Microwaves

Battery-Free Pacemaker Is Powered by Microwaves Now, researchers from Rice University have developed a battery-free pacemaker that can be implanted directly in heart.If the design is adopted, it could eliminate many of the common complications associated with pacemaker implantation.

Cosmic Rays Could Be Even More Dangerous to Mars Explorers Than Thought

Cosmic Rays Could Be Even More Dangerous to Mars Explorers Than Thought A new predictive model of radiation effects indicates we could be vastly underestimating the damaging effects of cosmic rays on astronauts.That means a trip to Mars could include a doubling of cancer risk compared with previous estimates.

NASA-Funded Startup to Build Fusion-Powered Rockets

NASA-Funded Startup to Build Fusion-Powered Rockets These reactors are big and (currently) inefficient, but a NASA-funded startup called Princeton Satellite Systems is working on a small-scale fusion reactor that could power advanced fusion rockets.All the forms of rocket propulsion we currently have involve accelerating propellant out of a nozzle.

Google Wants Your Help Documenting This Summer's Total Solar Eclipse

Google Wants Your Help Documenting This Summer's Total Solar Eclipse All across the US, citizen scientists will be snapping photos to create a film documenting the eclipse’s path.A total solar eclipse occurs when the sun is completely covered by the moon.

This Tiny Radioactive Implant is a Powerhouse for Treating Prostate Cancer

This Tiny Radioactive Implant is a Powerhouse for Treating Prostate Cancer ” Even though there does exist a less-extreme path that prostate cancer can take, there’s still a continuum of severity and aggression, just like there is for any kind of cancer.For those people who do require more aggressive treatments such as radiation, there’s a tiny implant among the relatively less-scary options for prostate cancer treatment.

Final Kepler Report Includes 219 New Potential Exoplanets

Final Kepler Report Includes 219 New Potential Exoplanets That’s what NASA’s Kepler space telescope has been doing these past eight years.These exoplanets were detected by Kepler using what’s known as the transit method.

Force Fields Become a Weapon in the Fight Against Prostate Cancer

Force Fields Become a Weapon in the Fight Against Prostate Cancer Scientists from the UK have figured out how to use a force field to separate cells, and it’s about to change prostate cancer research.One difference between normal and cancerous prostate cells is that where normal prostate cells use zinc to carry out their biologically ordained function, prostate cancers are devoid of zinc.

Single-Dose Radiation Found Effective for Prostate Cancer

Single-Dose Radiation Found Effective for Prostate Cancer Iridium also has isotopes that are useful in cancer treatment — and especially in prostate cancer treatment.The results of a two-year study from Europe have come in, concerning the use of iridium-192 in single-dose radiation therapy for prostate cancer.

New PillCam Uses Wireless Radio, CCD Cameras to Diagnose Heartburn

New PillCam Uses Wireless Radio, CCD Cameras to Diagnose Heartburn While the FDA has provisionally approved the PillCam for use, they only allow it after a patient has experienced an unsuccessful endoscopy or colonoscopy.There are three versions of the device: the PillCam ESO, for the esophagus, the PillCam SB for the stomach, and the PillCam Colon for the lower GI tract.

New Implants Could Treat Type 2 Diabetes Without Needles

New Implants Could Treat Type 2 Diabetes Without Needles Another condition that has resisted the implant approach is type 2 diabetes.But type 2 diabetes is more related to insulin insensitivity than it is to failure to produce insulin in the first place.

Possible Mars-sized Planet Detected in the Outer Solar System

Possible Mars-sized Planet Detected in the Outer Solar System A new paper published in the Astronomical Journal suggests that the unusual tilt of some Kuiper Belt objects could be explained by a Mars-sized planet lurking in the outer solar system.None of these are considered to be Kuiper Belt objects, all of which sit considerably closer to the sun.
